AI Technical Summary

Technical Problem

The existing branch scissor blade forming process cannot meet the customer's good product standards, and insufficient edge density leads to a short service life of the blade.

Method used

A new branch scissor edge forming process is adopted, including plate preparation, cutting and unloading, folding, red punching, milling and flanging, milling chamfering, deburring, heat treatment and surface treatment. Among them, the red punching step is realized by heating the transmission assembly, and the blade is heated and forged with the heating track and the red punching die to form a denser blade.

Benefits of technology

By increasing the blade density, the strength of the blade is enhanced, thereby extending the service life of the blade and meeting the customer's good product standards.

Abstract

The invention discloses a forming process for a cutting edge of a pair of branch scissors. The forming process comprises the following steps: S100, preparing a plate; s200, cutting and blanking are conducted, specifically, the whole plate is cut into a blank; s300, edge folding is conducted, specifically, the blank is subjected to edge folding, and the folded edge is the positioning piece; s400, red punching is carried out; s500, milling and flanging are conducted, specifically, multiple materials of the semi-finished product subjected to hot punching are flanged, and folded edges are removed; s600, chamfer milling is conducted, specifically, a chamfer on the product is machined on the semi-finished product; s700, deburring is carried out; s800, heat treatment, wherein the hardness of the product is improved; s900, surface treatment is carried out; wherein the step of S400 hot punching comprises the substeps that S410, a blade of a blank is heated; s420, forging and pressing the heated cutting edge to plasticize a cutting edge; and S430, naturally cooling the semi-finished product to improve the toughness of the product. The branch shear blade forming process is reasonable in design, the blade density of the blade is improved, the strength of the blade is guaranteed, and therefore the service life of the blade is prolonged.
