Due to the widespread application and excellent characteristics of drag chains, they can be perfectly applied on machine tools. Drag chains mainly play a certain role in traction and protection of cables on machine tool equipment. So what are the commonly used drag chains on machine tools? It can be roughly divided into plastic drag chains, steel drag chains, conduit protective sleeves, and rectangular hoses. So what are the performance and uses of the common types of drag chains on these types of machine tools?
drag chain
1.Introduction to steel drag chains
Structure
The main body of the TL series steel drag chain is composed of components such as a chain wrench (high-quality steel plate chrome plated), a support wrench (extruded aluminum alloy), a shaft pin (alloy steel), etc., which prevents relative movement and distortion between the cable or rubber tube and the drag chain. The chain wrench is chrome plated, with a novel and reasonable appearance, high flexibility and strength, good rigidity, easy installation, reliable use, and easy disassembly, especially using high-strength wear-resistant materials, Alloy copper is used as the pivot pin, which improves the wear resistance of the product, makes bending more flexible, reduces resistance, and reduces noise, thereby ensuring long-term use without deformation and sagging.
characteristic
1.The drag chain can adapt to a maximum movement speed of 40 meters/minute.
2.At the maximum moving speed of the drag chain, the noise sound pressure level shall not exceed 68 decibels.
3．The safe service life of the drag chain shall not be less than 1 million times (reciprocating).
2．Introduction to plastic drag chains
Structure
（1）The drag chain is shaped like a tank chain and consists of numerous unit links that rotate freely between them.
（2）The inner height, outer height, and pitch of the same series of drag chains are the same, and there are different options for the inner width and bending radius R.
（3）The unit chain link is composed of left and right chain plates and upper and lower cover plates. Each section of the drag chain can be opened, making it easy to assemble and disassemble without the need for threading. After opening the cover plate, cables, oil pipes, gas pipes, water pipes, etc. can be placed in the drag chain.
（4）Separaters can also be provided to separate the space within the chain as needed.
Characteristic
（1）Material: Reinforced nylon, with high pressure and tensile load, good toughness, high elasticity, and wear resistance, flame retardant, stable performance at high and low temperatures, suitable for outdoor use.
（2）Resistance: Oil and salt resistant, with a certain degree of acid and alkali resistance.
（3）Operating speed and acceleration (specific speed and acceleration depend on operating conditions).
（4）Long operating life.
Use to
（1）Suitable for use in reciprocating motion situations, it can provide traction and protection for built-in cables, oil pipes, air pipes, water pipes, etc.
（2）Each section of the drag chain can be opened for easy installation and maintenance. Low noise during exercise, wear-resistant, and able to move at high speeds.
（3）Drag chains have been widely used in CNC machine tools, electronic equipment, firefighting machinery, stone machinery, glass machinery, door and window machinery, injection molding machines, robotic arms, overweight transportation equipment, automated warehouses, and so on.
Principles for selecting drag chains：
1、Determine the height hg of the chain plate and the model of the drag chain based on the maximum aperture Dma of the support plate.
2、The inner cavity aperture of the support plate D1=d+is approximately equal to 0.1d (rounded to an integer). Where d=outer diameter of wires, cables, liquid and gas hoses.
3、Determine the bending radius of the supporting plate type drag chain based on the functional requirements of the drag chain：
1）When the size of the pipe joint of the cable is larger than the inner diameter of the support plate or requires frequent disassembly, repair, etc., a separate type of support plate can be selected；
2）When the drag chain needs to bear a larger pipe or cable load, it should choose a high-strength support plate type - whole block type;
3）When there are many specifications and varieties for installing pipe cables, frame type support plates can be selected.
4）When the use of machine tool drag chains is restricted or affected by environmental conditions, it is necessary to use steel strip protective support plates.
5）Determine the width b1 of the support plate based on the number of installed pipe cables, in order to determine the width B of the drag chain. Ad/201903113262.20 Desp Sample.pdf
