An integrated stamping forming process for the external attachment plate of the clip film chain

Abstract

The invention discloses an integrated punching and forming process for an external attachment plate of a clip film chain, comprising the following processing steps: a. punching guide positioning holes and process holes; b. punching holes, pressing grooves, and punching inner holes of the external attachment plate; c. Press concave, extrude boss, turn hole; d. Trimming twice; e. Press beveled edge; f. One pre-bending 45 degrees, fine punching, one bending 90 degrees; g. Extruding holes; h. The second pre-bending is 45 degrees, and the second bending is 90 degrees; i. Product cutting; j. Cutting off waste. This process realizes the reduction of equipment and procedures required for processing, improves the processing of external attachment plate grooves, bosses, bending accuracy and comprehensive quality, and improves the pass rate of stamping processing of external attachment plate parts.

Description

technical field [0001] The invention relates to the technical field of clip film chains, in particular to an integrated stamping and forming process for the external attachment plate of the clip film chain, which is suitable for processing the external attachment plate of the clip film chain in groove shape, punching bosses, turning holes, and multiple bending processes. Components. Background technique [0002] For a long time, the external attachment plate is a characteristic component part of the clip film chain, such as Figures 2 to 5 As shown, the features of the external attached plate: ① There are guide boss features symmetrically on both sides. Flip the hole, and the position is required to guide the center of the boss on both sides; ③ There is a groove on the top surface. After the groove is stamped and formed, the depth and straightness of the groove must be maintained, and there must be no stamping collapse, burrs, etc. The turning hole has a higher positional a...

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
