Pintle chain bending plate forming device

Abstract

The invention relates to a pintle chain bending plate forming device. The pintle chain bending plate forming device comprises an upper die structure and a lower die structure, wherein the upper die structure comprises an upper die plate, an upper base plate, an upper die base and an upper forming die, the upper die plate, the upper base plate and the upper die base abut against one another, the upper forming die is installed on the upper die base, the lower die structure comprises a positioning block, a lower forming die, a lower base plate, a bottom plate, a floating block, an ejector rod and an elastic block, a groove used for bending of a workpiece is formed in the center of the lower forming die, the positioning block is installed on the lower forming die, the floating block is arranged in the groove, the lower forming die and the bottom plate are installed in a matched mode through the lower base plate, ejector rod through holes are formed in the middle of the lower base plate and the middle of the bottom plate, the size of the groove is larger than that of the through hole in the middle of the lower base plate and that of the through hole in the middle of the bottom plate, the elastic block is fixed through an upper clamping plate and a lower clamping plate, one end of the ejector rod abuts against the floating block after penetrating through the through hole in the middle of the lower base plate and the through hole in the middle of the bottom plate, and the other end of the ejector rod is installed on the upper clamping plate and is in contact with the elastic block. According to the pintle chain bending plate forming device, the depth of parallelism of the two edges of a chain bending plate is increased, the precision of arcs bent by the chain bending plate is improved, the correction process and the chamfering process are omitted, and the quality of a chain is improved.

Description

technical field [0001] The invention relates to a forming device for a bent chain plate of a pinned chain, which belongs to the technical field of mechanical processing of base parts. Background technique [0002] At present, the forming of the curved chain plate for domestic sales is simple, the mold is simple, and the size after forming is difficult to meet the requirements at one time. A subsequent calibration process is required. There is a slippage problem during the forming process of the curved chain plate. The chamfering of the curved chain plate is an additional process. Therefore, there are problems of poor manufacturing quality and many processes. The present invention aims at these problems, ingeniously changes the mold, and completes the forming of the bent chain plate at one time, so as to solve the existing problems. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a pin-join...
