Introduction to Selection Principles of Machine Tool Chains

Introduction to Selection Principles of Machine Tool Chains The following is the selection principle of the machine drag chain:

1, support plate cavity diameter D1 = d + about equal to 0.1d (take an integer). Where d = the outside diameter of the wire, cable, liquid, and air hose.

2, according to the maximum aperture Dmax support plate to determine the chain height hg and drag chain model.

3, according to the drag chain function requirements to determine the support plate type of drag chain bending radius:

1) When the towline is required to carry a large pipe or cable load, the high-strength support plate type-block type shall be used;

2) When the size of pipe joints is greater than the bore diameter of the support plate or it must be frequently disassembled, repaired, etc., a separate type support plate may be used;

3) When the variety of specifications of the installation cable is large, the frame type support plate can be used;

4. The width b1 of the support plate is determined according to the number of installed tube cables, so that the width B of the drag chain is known.

5. When the use of drag chains is restricted or affected by the environment, it is necessary to use a steel belt protective support plate.
