Abstract

The invention relates to a drag chain, in particular to an easy-to-assemble drag chain with high anti-twisting strength and a preparation method thereof. The drag chain consists of a chain links which are distributed continuously in sequence, wherein each chain link comprises a pair of symmetrically distributed chain plates; the chain plates are positioned through a supporting plate; the head of each chain plate is provided with a head connecting end; the tail part of each chain plate is provided with a tail connecting end; the head connecting end is provided with a positioning boss; the tail connecting end is provided with a positioning hole; the head connecting end of one chain link is fixedly matched with the tail connecting end of another chain link; the positioning boss and the positioning hole are fixed through a positioning pin; each chain plate consists of a single piece of chain plate; a cable through hole is formed in the supporting plate. The preparation method comprises the following steps: blanking and forming, forming and heating, cooling, deburring, machining the positioning boss and the positioning hole, and electroplating. The easy-to-assemble drag chain with high anti-twisting strength and the preparation method thereof have the advantages of compact structure and capabilities of improving the aerial property, increasing the bearing capacity and enhancing the anti-twisting strength.

Description

technical field [0001] The invention relates to a towline, in particular to an easy-to-assemble towline with high anti-torsion strength and a preparation method thereof. Background technique [0002] The chain plates in the drag chains in the prior art are all formed by spot welding of two single pieces, which leads to cumbersome assembly procedures and high manufacturing costs. [0003] Chinese patent 200880112506.4 discloses a cable drag chain, which is formed by connecting a plurality of frames to each other rotatably. Long objects such as cables are arranged in the guide part surrounded by each frame. It is characterized in that it has : a rotation angle limiting mechanism that limits the rotation angle of the frame; and a brake mechanism that applies a brake to the rotation of the frame before the limit of the rotation angle, the rotation angle limiting mechanism is composed of a brake integrally formed on each frame The brake plate and the brake receiver are formed,...
