Engineering plastic drag chain is divided into plastic engineering drag chain and steel engineering drag chain according to raw materials. According to the structure, it is divided into bridge engineering drag chain and fully enclosed engineering drag chain. The engineering plastic drag chain has beautiful shape, light weight, and can be adjusted at will. The engineering plastic drag chain is suitable for use in reciprocating motion. It can pull and protect the built-in cables, oil pipes, gas pipes, water pipes, etc. Each section of the drag chain can be opened to facilitate installation and repair. Low noise, wear resistance and high-speed movement. Drag chain has been widely used in CNC machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, injection molding machine, manipulator, lifting and transportation equipment, automated warehouse, etc. Structure of drag chain: the drag chain looks like a tank chain and is composed of many unit links. The links roll freely. The inner height, outer height and pitch of the drag chain of the same series are the same, and the inner height and zigzag radius r of the drag chain can be selected differently. The unit chain link is composed of a swing chain plate and upper and lower cover plates. Each section of the drag chain can be opened for easy assembly and disassembly without threading. After opening the cover plate, the cable, oil pipe, gas pipe, etc. can be put into the drag chain.

The engineering plastic drag chain is applicable to CNC machine tools, machining centers, automatic machinery, production lines and other machine tools, robots, transportation machinery, measuring instruments, transfer equipment and other drive controls. As the protective equipment for wires, cables, liquid and gas hoses, it can operate in coordination with the moving parts of machines, machinery and equipment, reflect the ability of safety protection and guidance, and extend the protected wires, cables, liquid The service life of air hoses can reduce consumption, greatly improve the scattered and disordered condition of wires, cables, liquid and air hoses of machine tools and mechanical equipment, make them orderly and orderly placed together, and enhance the overall artistic appearance effect of machine tools and mechanical equipment.

Specification for model selection of engineering plastic drag chain: inner diameter height: the built-in cable shall be selected. The thickest of the oil pipe, gas pipe, water pipe, etc. is taken as the reference height. Add at least 10% of the height space as the inner cavity height of the drag chain. Assuming that the cable oil pipe, gas pipe, water pipe, etc. need to be stacked, the actual cavity height after stacking shall be taken as the reference height.

(1) the drag chain looks like a tank chain, which is composed of many unit connections, and the connections roll freely.

(2) the inner height, outer height and pitch of the drag chain of the same series are the same, and the inner width and zigzag radius r of the drag chain can be selected differently.

(3) the unit chain link is composed of a swinging chain plate and upper and lower cover plates. Each section of the drag chain can be opened for easy installation and disassembly without threading. After opening the cover plate, the cable, oil pipe, gas pipe, water pipe, etc. can be put into the drag chain.

(4) separators can also be provided to separate the space in the chain as required.
