Example Embodiment

[0020] Example one:

[0021] First, blank the material, use a die to punch along the closed curve, the punched part is used to manufacture flat parts of various shapes, use the die to punch along the closed curve, the punched part is waste, and then trim, the formed part The edges are trimmed neatly or cut into a certain shape, and punched along an unclosed curve with a die to produce separation; the sheet blank is formed into various open hollow parts, and the edge of the sheet or semi-finished product is formed into a certain curvature along a certain curve. Form an upright edge, improve the dimensional accuracy of the formed parts or obtain a small fillet radius through shaping, and make an upright edge on a pre-punched sheet or semi-finished or unpunched sheet, and the board is bent The material is bent into various shapes along a straight line to obtain parts with complex shapes.

Example Embodiment

[0022] Embodiment two:

[0023] Firstly, blanking, punching along the closed curve with a die, the punched part is a part, used to manufacture flat parts of various shapes, with a punching die along the closed curve, the punched part is waste, the punching process, ensure the convex and concave mold The machining accuracy and assembly quality of the punch are ensured to ensure the verticality and side pressure of the punch and the entire punch must have sufficient rigidity. When installing the punch, ensure the correct clearance of the punch and the concave mold and make the punch and concave mold be installed firmly on the mold fixing plate. The end surface of the die should be kept parallel to the working table of the press; the die structure is increased by the pressure plate (or support plate), and the plate and the pressure plate are in contact with the pressure plate, and there is a certain pressure. Check the die edge if there is a reverse taper. The cutting edge of the di...

[0024] Embodiment three:

[0025] In the second embodiment, the following steps are added:

[0026] Firstly, blanking, punching along the closed curve with a die, the punched part is a part, used to manufacture flat parts of various shapes, with a punching die along the closed curve, the punched part is waste, the punching process, ensure the convex and concave mold The machining accuracy and assembly quality of the punch are ensured to ensure the verticality and side pressure of the punch and the entire punch must have sufficient rigidity. When installing the punch, ensure the correct clearance of the punch and the concave mold and make the punch and concave mold be installed firmly on the mold fixing plate. The end surface of the die should be kept parallel to the working table of the press; the die structure is increased by the pressure plate (or support plate), and the plate and the pressure plate are in contact with the pressure plate, and there is a certain pressure.

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...
