Damage-free automatic chain bending mechanism for high-intensity metal round link chains

Abstract

The invention belongs to the technical field of knitting metal round link chains, specifically relating to an automatic chain bending device for producing medium and large-scale high-intensity metal round link chains. The automatic chain bending device comprises a main chain bending oil cylinder, a chain bending slide carriage, a left chain bending mechanism and a right chain bending mechanism, wherein the main chain welding oil cylinder is a power and control mechanism for shifting the chain bending slide carriage; the left and right chain bending mechanisms are symmetrically installed on both sides of the chain bending slide carriage, are in the same structures and respectively comprises a chain bending oil cylinder, a lever connecting plate, a chain bending lever, a roller support, a roller shaft and a roller which are main executing mechanisms for bending bar stocks into chain links. The invention has the advantage of ingenious and reasonable structure; due to the adoption of the roll forming technique, the metal bar stocks have no damages in the chain welding process, and the fabricated metal round link chains have high intensity.

Description

High-strength metal round link chain without damage automatic chain bending mechanism technical field The invention belongs to the technical field of metal circular link chain knitting, and in particular relates to a non-damaging automatic chain bending mechanism for producing medium, large, and high-strength metal circular link chains. Background technique During the fully automatic production and knitting process of medium and large-sized high-strength metal round link chains, the metal bars must not be damaged during the chain bending process to ensure the strength of the high-strength metal round link chains. At present, in the production of medium and large-scale high-strength metal round link chains in China, the method of stamping or extruding bending chains is generally adopted for metal bar bending chains. Increased the strength of the metal ring chain. There are also some advanced automatic knitting equipment imported from abroad to complete by rolling, but the ...

At present, in the production of medium and large-scale high-strength metal round link chains in China, the method of stamping or extruding bending chains is generally adopted for metal bar bending chains. Increased the strength of the metal ring chain

There are also some advanced automatic knitting equipment imported from abroad that are completed by rolling, but the price of this imported equipment is high, and it is difficult to maintain and replace spare parts. For ordinary manufacturers, it is unacceptable.
