Integrated stamping forming process for attached plate of film clamping chain

Abstract

The invention discloses an integrated stamping forming process for an attached plate of a film clamping chain. The integrated stamping forming process comprises the following processing steps of: a, stamping guide positioning holes and a process hole; b, stamping and pressing a groove, and stamping an inner hole of the attached plate; c, stamping and concaving, extruding a lug boss and performinghole-flanging; d, trimming twice; e, pressing a bevel edge; f, pre-bending by 45 degrees for a first time, performing fine stamping and bending by 90 degrees for a first time; g, performing hole extrusion; h, pre-bending by 45 degrees for a second time and pre-bending by 90 degrees for a second time; i, performing product blanking; and j, cutting off waste. In case of reducing equipment and procedures needed for processing, the integrated stamping forming process improves the attached plate groove processing quality, the lug boss processing quality, bending precision and comprehensive quality,and improves the qualification rate of stamping and processing an attached plate part.

Description

Technical field [0001] The present invention relates to the technical field of clip film chains, in particular to an integrated stamping forming process for the outer attachment plate of the clip film chain, which is suitable for pressing groove shapes, punching bosses, turning holes, and multiple bending processes of the outer attachment plate of the sandwich film chain. Components. Background technique [0002] For a long time, the external attachment plate is a characteristic component of the sandwich chain chain, such as Figure 2 to 5 As shown, the characteristics of the attached board: ① There are symmetrical guide bosses on both sides, the flatness and parallelism of the bosses on both sides after pressing are relatively high, and the precision of the fit needs to be ensured; ②The top surface has Turn the hole, and the position is required to guide the center of the boss on both sides; ③There is a groove on the top surface. After the groove is stamped and formed, the groove...

AI Technical Summary

Problems solved by technology

[0004] 1) The forming groove produces material flow deformation, and the difficulty of trimming after forming is relatively large, which has buried hidden dangers for product quality. For example, the relative position of the groove and the turning hole is deviated due to deformation, which affects the matching accuracy of the assembly

[0005] 2) Changing the positioning references of the process of bending, punching the boss, and pressing the groove many times reduces the precision of the stamping forming and reduces the quality of the parts. After forming, some parts need to be reshaped

[0006] 3) Due to the single-process processing, each process requires manual feeding and positioning, resulting in low stamping accuracy of the parts and easy to produce unqualified products

[0007] 4) The whole processing process has many procedures, takes up a lot of equipment, requires a lot of labor, complex operation, high energy consumption, and low production efficiency
