Heavy-duty engineering plastic drag chains are suitable for reciprocating motion environments. Their main function is to pull and protect built-in cables, oil pipes, air pipes, water pipes, etc.

Technical parameters

Inner height: Select the thickest cable, oil pipe, air pipe, water pipe as the reference height, and add at least 10% of the space as the inner height Hi of the drag chain. If overlap occurs, the actual height after overlap should be used as the reference height.

Inner width: Select thicker cables, oil pipes, air pipes, and water pipes, and their total outer diameter as a reference for the inner width of the drag chain, and ensure that there is at least 10% of the width space.

Bending radius: Select the largest bending radius of the built-in cables, oil pipes, air pipes, and water pipes as the reference value, and reserve more than 10% of the space.

Placement principles

The placement of cables, oil pipes, water pipes and air pipes in the drag chain should follow the following principles: Keep 15% of the remaining space so that the built-in cables, oil pipes, etc. can move freely, and do not apply tension to the drag chain in the radial direction. Wires with large diameter differences should be arranged separately, and the weight should be evenly distributed. If necessary, they can be separated by separators. When running at high speed or high frequency, the wires should be separated on the horizontal plane as much as possible to avoid overlapping. When there are a large number of cables, air pipes and oil pipes, it is recommended to use separators.

Features and applications

The load-bearing engineering plastic drag chain has the following characteristics:

Each section can be opened for easy installation and maintenance.

Low noise and good wear resistance during movement, and high-speed movement can be achieved.

It is widely used in many fields, including CNC machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, injection molding machines, manipulators, lifting and transportation equipment, and automated warehouses.

Structural features

1. The drag chain looks like a tank chain and is composed of multiple unit links that can rotate flexibly.

2. The inner height, outer height and pitch of the same series of drag chains are the same. The inner height and bending radius R of the drag chain can be selected in different sizes according to needs.

3. The unit chain link consists of left and right chain plates and upper and lower covers. Each section can be opened, which is easy to assemble and disassemble without threading. After opening the cover, cables, oil pipes, air pipes, etc. can be placed in the drag chain.

4. In addition, separators can be provided to divide the space in the chain.
