In 1953, Professor Dr Gilbert waninger of Germany invented the world's first steel drag chain. Dr Waldrich, the holder of kabelschlepp jiabora, believes that drag chain is a new market, which can create huge demand. He began to promote * drag chains to the market in 1954.
Now many original steel drag chain models have been improved to all kinds of steel and plastic drag chains, which are widely used in many fields. Kabelschlepp jiabora company has successfully created more: Portable drag chain, 3D drag chain and connectionless drag chain. An idea more than 50 years ago created today's huge market.
It is generally used in the protection of machine tools, air pipes, oil pipes, drag pipes, etc.
The use of drag chain originated in Germany at first, and then the structure was quoted and innovated in China.
Now the drag chain has been widely used on the machine tool, which protects the cable and makes the whole machine tool look more beautiful.
Drag chain, rectangular metal hose, protective sleeve, bellows and plastic coated metal hose all belong to cable protection products. Drag chain is divided into steel drag chain and plastic drag chain. Steel drag chain is composed of steel and aluminum and can be customized. Plastic drag chain is also known as engineering drag chain and tank chain.
The drag chain can be divided into bridge drag chain, fully closed drag chain and semi closed drag chain according to the use environment and use requirements.
Application and characteristics of plastic drag chain
(1) It is suitable for the occasion of reciprocating motion, and can traction and protect the built-in cables, oil pipes, gas pipes, water pipes, etc.
(2) Each section of the drag chain can be opened to facilitate installation and maintenance. Low noise and wear resistance during movement, and can move at high speed.
(3) Drag chain has been widely used in CNC machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, injection molding machine, manipulator, overweight transportation equipment, automatic warehouse and so on.
Structure of plastic drag chain
(1) The shape of the drag chain is like a tank chain, which is composed of many unit links, and the links rotate freely.
(2) The inner height, outer height and pitch of the same series of drag chains are the same, and the inner width and bending radius r of the drag chain can be selected differently.
(3) The unit chain link is composed of left and right chain plates and upper and lower cover plates. Each link of the drag chain can be opened for convenient assembly and disassembly without threading. After opening the cover plate, the cable, oil pipe, air 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 needed.
Basic parameters of plastic drag chain
(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 temperature, and can be used outdoors.
(2) Resistance: resistant to oil and salt, and has certain acid and alkali resistance.
(3) Depending on the operating speed and acceleration.
(4) Operating life.
