Problems solved by technology

[0004] However, the stamping parts produced by the existing stamping technology have defects such as cracking, stacking, waves, roughening, deformation, burrs, lack of material, and inconsistent dimensions, which affect the quality of the stamping parts. Therefore, we propose a stamping part production process

Embodiment 1

[0021] First blanking, punching along the closed curve with a die, the punched part is a part, used to manufacture flat parts of various shapes, punching along a closed curve with a die, the punched part is waste, and then trimming, the formed part The edge is trimmed neatly or cut into a certain shape, and separated by punching along an unclosed curve with a die; the sheet blank is formed into various open hollow parts, and the edge of the sheet or semi-finished product is formed along a certain curve according to a certain curvature. Form a vertical edge, improve the dimensional accuracy of the formed part or obtain a small fillet radius by shaping, make a vertical edge on a pre-punched sheet or semi-finished product or an unpunched sheet, and bend the sheet The material is bent into various shapes along a straight line to obtain parts with complex shapes.

Embodiment 2

[0023] First blanking, punching along the closed curve with a die, the punched part is a part, used to manufacture flat parts of various shapes, punched along a closed curve with a die, the punched part is waste, during the punching process, the convex and concave dies are guaranteed The processing accuracy and assembly quality ensure the verticality of the punch and the side pressure and the entire punch must have sufficient rigidity. When installing the punch, ensure the correct gap between the punch and the die and make the punch and die installed firmly on the mold fixing plate. Up and down The end face of the mold should be kept parallel to the working surface of the press; the mold structure should be increased with a pressure plate (or support plate) plate that is in contact with the plane of the pressure plate and has a certain pressure. Check the cutting edge of the die if there is a reverse taper Then the cutting edge of the die must be properly trimmed. When the shap...

Abstract

The invention discloses a stamping part production process. The stamping part production process comprises the following steps that (1) separation is carried out, specifically, blanking is carried outfirstly, stamping is carried out through a stamping die along a closed curve, the portion stamped off is a part which is used for manufacturing flat plate parts in various shapes, stamping is carriedout through the stamping die along the closed curve, the portion stamped off is scraps, then trimming is carried out, the edge of the formed part is trimmed to be regular or to be in a certain shape,and stamping is carried out through the stamping die along a non-closed curve to generate separation; and (2) molding is carried out, specifically, a plate blank is made into various opening hollow parts, the edge of a plate or a semi-finished product is made to be vertical along a certain curve at certain curvature, and the size precision of the molded part is improved or small corner radius isobtained in a shaping mode. Various measures are taken for defects, the quality of stamping parts is ensured, and the problem that due to the defects of cracking, stacking, waving, galling, deformation, burrs, material lack, unqualified size and the like of stamping parts produced by an existing stamping technology, the quality of the stamping parts is affected is solved.

Description

technical field [0001] The invention relates to the technical field of part processing, in particular to a stamping part production process. Background technique [0002] Stamping parts are formed by applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. [0003] Stamping parts are mainly formed by stamping metal or non-metal sheet materials through stamping dies under the pressure of a press. It mainly has the following characteristics: (1) Stamping parts are manufactured by stamping on the premise of low material consumption Its parts are light in weight and good in rigidity, and after the sheet metal is plastically deformed, the internal st...
