The steel drag chain is composed of chain levers, support levers, shaft pins and other components, so that there is no relative movement between the cable or rubber tube and the drag chain, and no distortion occurs. The Steering Drag Link lever is chrome-plated with a novel appearance and reasonable structure, smart strength High rigidity, good rigidity, no deformation, good abrasion resistance and low resistance. It is generally used for traction and protection on cables, oil pipes, air pipes, water pipes, and air pipes of machine tools. Its application on the machine tool not only protects the cable, but also makes the machine look more beautiful. The selection of steel drag chains generally refers to the following factors:
What factors should be considered when purchasing steel drag chains?
First, determine the height hg of the chain plate and the model of the drag chain according to the maximum hole diameter Dma of the support plate.
Second, the bore diameter of the inner cavity of the support plate D1=d+ is approximately equal to 0.1d (take an integer). Where d = outer diameter of wire, cable, liquid and gas hose.
Third, determine the bending radius of the supporting plate type of the drag chain according to the functional requirements of the drag chain:
1. When the size of the pipe joint of the pipe cable is larger than the inner cavity of the support plate or frequent disassembly, assembly, maintenance, etc., a separate type support plate can be selected;
2. When the drag chain needs to carry a large pipe and cable load, a high-strength support plate type-one-piece type should be selected;
3. When there are many types of installation tubing and cable specifications, frame type support plates can be selected.
4. when the use of machine tool drag chains is restricted or affected by the environment, and steel belt protective support plates are required.
5.determine the width b1 of the support plate according to the number of cables installed, so that the width of the drag chain B is known.
