The manufacturer of permanent magnet hoist talks about the characteristics of the block and the method of winding

The block is a very important accessory for lifting equipment. The pulley block consists of a fixed pulley and a movable pulley with a rope. The rope passes in series between the pulleys. The manufacturer of the permanent magnet hoisting device tells you that the fixed block does not move, only the pulley rotates, and the moving block moves synchronously with the heavy object, saving effort. Moreover, the more pulleys in the block, the greater the effort, but the moving speed at noon is correspondingly slower. The manufacturer of permanent magnet hoisting device tells you that threading and winding of steel wire rope is an important and complicated task. The winding and winding quality of the wire rope directly affects the smooth progress of the lifting operation. If the windings are improperly wound, the resistance of the steel wire ropes in the group will change greatly during the movement, which will cause the upper and lower carriages to tilt. In severe cases, the heavy objects will lock themselves during the descending process. The manufacturer of the permanent magnet hoisting device tells you that sometimes due to the poor transmission of the wire rope, the wire rope part of the block is loose, which will cause sudden vibration when lifting heavy objects. When the impact load is large, the wire rope will break and cause an accident. The manufacturer of the permanent magnet hoist tells you that the threading and winding of the wire rope in the block should be carried out according to the specific conditions of the lifting operation, and appropriate threading and winding methods should be adopted. When buying a pulley block, first pay attention to whether the product design is reasonable and whether the quality meets the requirements for use. At the same time, pay more attention during use and check regularly as required. This is the correct way to use it. Zhejiang Kaixin Magnetic Machinery Co., Ltd. is one of the manufacturers of permanent magnet spreaders and vacuum spreaders. The main products are permanent magnet jacks, permanent magnet hoisting devices, electronically controlled permanent magnet chucks, etc. The products are distributed all over the country, and are widely used in machining, mold manufacturing, engineering machinery, shipbuilding and other industries.

The permanent magnet jack manufacturer tells you how to make the lifting belt last longer

The manufacturer of the permanent magnet lifter tells you that if you want to use the lifting belt for a longer time, you must first choose a regular manufacturer. In the basic principles and methods of lifting operations, you should first consider choosing a suitable spreader. In recent years, the spreader industry in my country has developed rapidly, but the technical standards are not perfect and there is a lack of mandatory standards. Some domestic enterprises produce arbitrarily, even lower the safety factor, some cases of contract processing and non-standard production. The actual quality of the sling is uneven, and there are certain safety risks. Therefore, it is necessary to choose a formal manufacturer and establish a corresponding management system. Before moving before factory inspection, the purchased sling must be produced and inspected by a professional manufacturer, and has a certificate and maintenance manual. The rated lifting weight, production number, production date and manufacturer of the product must be in obvious places that are not easy to wear. Name and other signs. The permanent magnet jack manufacturer tells you that if conditions permit, you can go to the supplier’s production plant for quality supervision. Add a load-bearing test. For bulk purchases, you can extract them for professional measurement to effectively check whether the rated load meets the requirements. The permanent magnet jack manufacturer tells you that if necessary, you can cut the sheath to check whether the number of core joints exceeds the standard and whether the material is qualified. Add a load-bearing test. For bulk purchases, you can extract them for professional measurement to effectively check whether the rated load meets the requirements. The permanent magnet jack manufacturer tells you that if necessary, you can cut the sheath to check whether the number of core joints exceeds the standard and whether the material is qualified. Strict inspection before use. In the daily inspection of certain units, it is not enough to damage the outer sheath and inner core of the lifting belt. Many units neglect the elasticity check of the flexible sling. The manufacturer of the permanent magnet jack tells you that the circumference should be re-measured according to the standard and compared with the standard circumference. Employees should be informed of the standard length of each sling and how much it cannot be stretched to determine whether it meets the flexibility requirements.

Talking about the manufacturer of permanent magnet hoist: how to use hoisting tackle efficiently

The lifting pulley is a simple lifting machine that vertically lifts the weight through a sprocket or reel. It is light, compact, easy to use, suitable for simple lifting work in construction. Depending on the number of wheels, the lifting and original supports can be divided into single-door slides, double-door pulleys and multi-door pulleys. There are four types of high-hook impactors, sprocket cyclists, suspension ring skateboards and sling pulleys are divided into hooks, sprocket cyclists, suspension ring sliding and sling pulleys. Efficient use of labor-saving vehicles can achieve half the effort. The following permanent magnet hoist manufacturers will take you to understand. The manufacturer of the permanent magnet hoisting device tells you that when the direction of the lifting pulley changes, or when the hook pulley is not used in high altitude operations, it is not recommended to use the hook pulley to prevent the hook from being removed. If hanging pulleys are used, protective measures should be taken. If after the hook, the hook is sealed with a thin wire so that the hook cannot be taken out; or use a hook with a tube, when the hook is hung, the hook is more convenient. Under the action of the spring, the Caucasian is bounced up and seals the hook. The manufacturer of the permanent magnet hoist tells you that the pulley cannot be overloaded. When there are cracks or defects, the pulley will not be put into use. Other parts, such as hooks, shafts, pull plates, etc., are not allowed to be used when required. When walling, you should pay attention to the angle of the wire rope in the pulley box. In any case, the deviation of the pulley shall not exceed 4°~6°. Because when the polarity of the wire rope is too large in the pulley box, the abrasion of the wire rope and the side of the pulley are intensified. On the other hand, the wire rope can easily slip out of the rope groove, so even if it is an accident, the lifting operation cannot be performed normally. If only one of these bags is used, the weight should be reduced accordingly, and the original weight cannot be used. The manufacturer of the permanent magnet hoist tells you that when the pulley block is worn out, you should try it first, check the part, there is no casing, friction or wire rope. If there is anything, it should be officially adjusted to formal. The rope that wears the sling or pulley block must meet the requirements of the pulley. When the diameter of the wire rope used exceeds the requirement of the pulley, we will increase the wear of the pulley, and the wear of the wire rope will also increase. The weight of the pulley must be equipped with corresponding thick steel wire.

What are the common problems of electronically controlled permanent magnet chuck

In the processing field, the electronically controlled permanent magnet chuck can be used as a machining center fixing device to install, position and fix the workpiece. Although many advantages of electronically controlled permanent magnet chuck fixtures cannot be replaced by traditional tooling fixtures, no tool can guarantee perfection. There are still some problems in the process from selection to use of the electronically controlled permanent magnet chuck. In order to make your electronically controlled permanent magnet chuck fixture use more smoothly, we have listed four problems and proposed countermeasures, hoping to help people who use electronically controlled permanent magnet chuck fixtures. Question 1: How to determine the appropriate electronically controlled permanent magnet chuck fixture? The choice of electronically controlled permanent magnet chuck fixture mainly depends on the user's purpose. There are different suction cups for different purposes. Common categories include suction cups for milling machines, suction cups for lathes, suction cups for grinders, suction cups for switch rails, and suction cups for high temperature quenching. Question 2: Will the processed workpiece material affect the adsorption effect? Generally speaking, as long as it is a magnetically conductive workpiece, there is no problem. If it is stainless steel or a material with high carbon content, you cannot use an electrically controlled permanent magnet chuck clamp. Question 3: What is the reason why the workpiece cannot be magnetized? First judge the material properties of the workpiece, and then check whether the workpiece is too small. Too small workpieces need to be fixed with clamps or guide blocks to increase resistance. If there is no problem, please check the rectifier to see if the fuse is blown and the power input and output are normal. Question 4: What is the reason why the new electronically controlled permanent magnet chuck fixing device cannot attract magnetism? First check whether the AC input power is connected and the voltage is correct. Then check whether the suction cup power cord is disconnected or disconnected, and then check whether the rectifier switch and display settings are correct and whether the fuse is burned. It is emphasized here that the use of the electronically controlled permanent magnet chuck should strictly follow the instructions.

Talking about the manufacturer of electronically controlled permanent magnet sucker: analysis of the cause of the heavy object falling in the use of sling

Spreaders, rigging and their end fittings are usually used for lifting operations. According to industry habits, we call the rigid retrieval equipment used for lifting operations as spreaders, such as hooks, grabs, clamps and suction cups. Dedicated slings, etc. The winding tool used to fasten the workpiece is called rigging, such as steel wire rope, chain, synthetic fiber sling and other commonly used end accessories including loops, shackles, rope clamps, etc. The manufacturer of electronically controlled permanent magnet suction cups will take you to analyze the causes of heavy objects falling in the use of slings. Falling heavy objects is an important blow injury in a lifting accident, including secondary injuries caused by scattered heavy objects. The manufacturer of the electronically controlled permanent magnet sucker tells you that the reasons for the fall include improper use of the sling, improper binding of heavy objects, unhooking of the hook, sudden power failure of the suction cup, and standardized application of the sling, which can improve the safety and reliability of the equipment itself Sex. Operation process. Work efficiency will play an important role. At the same time, the process and characteristics of the lifting operation determine that the lifting operation is a special operation with a higher degree of risk. As the operators conduct irregular inspections and improper use of these slings during use, accidents often occur. There are too many situations in this regard. Therefore, although the lifting sling is small, it is very important and should not be ignored. The electronically controlled permanent magnet suction cup manufacturer tells you that the statistical analysis of lifting accidents shows that the lifting accidents caused by incorrect selection of slings and improper use account for a large proportion of the lifting position of the workpiece, especially when lifting some large workpieces. Due to the low technical quality or low sense of responsibility of the people connecting with the cables, they often cause accidents and cause huge economic losses. For example, when the hook of a certain unit uses the steel wire rope in the double pocket to lift a total of about several tons of steel plate, the wire rope diameter is too small for overload lifting, and its edges and corners are not protected. During filling, when the steel plate is raised to a height of about 1 meter, the steel wire rope breaks at the corner, causing the steel plate to fall. To give another example, when the hook of a certain unit unloads a heavy workpiece from a flatbed truck, due to an illegal operation, the workpiece itself is fitted with a lifting ring, and only one of them is lifted. After lifting, the workpiece fell, and the impact force broke the wire rope, causing the workpiece to fall. Therefore, do not be careless in the use and management of the sling.

Talking about the manufacturer of electronically controlled permanent magnet chuck: how to use hoisting tackle efficiently

The operation of the lifting tackle is relatively simple, and heavy objects can be lifted vertically through the sprocket or the drum. Light weight, compact structure, easy to use, suitable for simple construction lifting work. According to the number of wheels, lifting tackle can be divided into single-door tackle, double-door tackle and multi-door tackle. According to the connection mode of the block and the hanging object, it can be divided into four types: hook block, chain link block, ring block and hanging block. Effective use of lifting tackle can achieve a multiplier effect with half the effort. The following electronically controlled permanent magnet suction cup manufacturers will take you to know the specific method: The manufacturer of the electronically controlled permanent magnet chuck tells you that when the direction of the force acting on the lifting block changes greatly, or when working at high altitudes, it is recommended not to use hooks to prevent unhooking. If a hook block is used, protective measures should be taken. For example, after hanging the hook, seal the opening of the hook with a thin wire so that the hook cannot be removed. Or use a hook with a cable board, which is more convenient to use. When the hook is hung, the cable plate bounces up under the action of the spring to seal the hook opening. The pulley should not be overloaded, and do not use the pulley if it is broken or damaged. If other parts do not meet the requirements for use, they are not allowed to be used, such as hooks, shafts and pull plates. The manufacturer of the electronically controlled permanent magnet sucker tells you that when threading the pulley block of the lifting tool, please pay attention to the angle of the wire rope in the pulley groove. In any case, the deflection angle of the pulley groove shall not exceed 4°~6°. Because, when the deflection angle of the wire rope in the pulley groove is too large, the wear on the side of the wire rope and the pulley groove increases. On the other hand, the wire rope is easy to slip out of the wire rope groove, so that the lifting operation cannot be performed normally, and an accident may even occur. The manufacturer of the electronically controlled permanent magnet sucker tells you that if only a few doors are used for multiple doors, the lifting capacity should be reduced accordingly after the conversion, and the original lifting capacity cannot be used. When the pulley block is used after tightening and winding, it should first be hoisted for testing. Check in detail whether each part is in good condition, and whether there is rope jamming, friction or friction between the wire ropes. If there is any problem, it should be lifted after adjustment. The manufacturer of the electronically controlled permanent magnet chuck tells you that the wire rope passed around the lifting tool block must meet the requirements of the block. When the diameter of the selected wire rope exceeds the requirement of the pulley, the wear of the pulley will increase, and the wear of the wire rope will also increase. A pulley with a certain lifting capacity should be equipped with a wire rope of corresponding thickness. Zhejiang Kaixin Magnetic Machinery Co., Ltd. was established in 2000.

Permanent magnet jacks are power-saving lifting equipment

The development of permanent magnet jacks has driven the development of many industries. In the past, electromagnetic jacks were the main products used to lift and transport ferromagnetic objects in industries such as shipbuilding, metallurgy and machinery manufacturing. By energizing the coil, and then through the magnetic field generated by the dotted coil, attracting the reminder object to achieve the purpose of attraction. In the working process, there are problems such as large size, self-weight, easy heating, short life and high power consumption, as well as the need to tow cables during work, high usage costs, many unsafe hidden dangers and heavy maintenance, which affect Workload. Permanent magnet jacks solve this problem, do not require electricity, and reduce costs. The basic feature of the permanent magnet jack is: in the process of lifting the adsorbed object, no external current is needed, and the strong magnetic force of the permanent magnet itself attracts and lifts ferromagnetic objects, such as steel. Therefore, compared with traditional electromagnetic jacks, the biggest advantage of permanent magnet jacks is to save energy. Because it can absorb heavy work without powering on, there will be no accidents due to power outages during work. Therefore, another advantage of permanent magnet jacks is that they are safe and reliable, and because they do not require power-off equipment, they are beneficial to reduce costs.
