Plastic Nylon Materials For Cnc Router Machine

1, the upper cover plate and the lower cover plate and the upper connector and the lower connector only use interference fit connection, in order to achieve a certain structural strength, the need to use a larger amount of interference, even plastic materials will be difficult to assemble, and plastic parts are easy to be affected by temperature and production process, which may lead to insufficient interference at some joints and lead to the cover plate falling off. The interference of part of the joint is too large, which makes the cover plate difficult to assemble and disassemble.

2, the use of interference fit connection, in the mechanical reciprocating movement, the cover plate relative to the connector will have a small displacement, long-term high strength use is easy to make the cover plate because of the accumulation of small displacement and fall off from the connector;

3, the cover plate is only set through the hole, disassembly, the worker usually through the screwdriver in the middle of a cover plate, the knife edge is placed under the adjacent cover plate, through the lever principle to warp one end of the cover plate, and then hold the cover plate by hand, fold to the other end of the cover plate, the operation is easy to make the plastic near the through hole distortion, and affect the structural strength when assembling again.

Structure

Drag Chain looks like the tank chain drg chain, consists of alot of link. Link is composed of the up and down or so four sections, each section can open, convenient installation, open the cover plate after put in the cable, tubing, the trachea, etc.

Material and Performance

Material: Reinforced nylon, good toughness and wear resistance, acid and alkali resistant ability.
Operating Life: Under normal use, up to 5 million reciprocating motion.

 Drag Chain Selection

High: Select the built-in cable, tubing, the trachea and conduit maximum height for reference, the height of the drag chain at least 10% of the remaining space.

Wide: Choose the built-in cable, tubing, trachea, the sum of its outer diameter for reference, the width of the drag chain at least 10% of the remaining space.
