Problems solved by technology

[0003] The stamping process has very high requirements on the precision of the process. If one process cannot meet the process requirements, the subsequent process will further increase the error of the workpiece, so that the sheet metal parts cannot be used, resulting in the scrapping of the workpiece.
The stamping forming of the arc surface has higher requirements on the processing technology, because it is easy to produce gaps in the process of arc surface processing, and due to the continuous stamping process of the mold, the arc surface of the workpiece is not enough, and it is easy to produce arc surface deformation. At the same time, The process of embossing and punching on the arc surface is also an important issue in the forming process

Embodiment Construction

[0016] The technical solutions in the embodiments of the present invention are clearly and completely described below.

[0017] A stamping process for sheet metal parts, comprising the following process steps:

[0018] a. Punching and trimming: Punching and punching the workpiece to be processed, and then punching the edge of the workpiece to obtain the required shape and size of the workpiece;

[0019] b. Embossing and embossing: embossing the workpiece, and then embossing the completed mold for embossing;

[0020] c. Arcing: use the characteristics of the upper and lower molds of the mold to complete the forming of the workpiece from the plane to the arc;

[0021] d. Interruption and bending: the formed arc surface is broken and bent, and the two sides of the arc surface are diagonally bent, and the bending angle is 30°;

[0022] e. Side pushing and flattening: Use the side pushing and flattening devices on both sides of the mold to push and flatten the partial surface of ...

Abstract

The invention relates to the sheet metal industry, in particular to a sheet metal part stamping process. The sheet metal part stamping process comprises the following steps: a, punching and trimming; b, raising and deburring; c, cambering; d, removing offsets and bending; and e, side pushing and leveling. The sheet metal part stamping process is reasonable in structure, the quality problem in the cambered surface molding process is effectively relieved, the precision of a molded cambered surface is guaranteed, meanwhile, damage to a die in the molding process is effectively reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to the sheet metal industry, in particular to a stamping process for sheet metal parts. Background technique [0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to a sheet metal material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] The stamping process has very high requirements on the precision of the process. If one process cannot meet the process requirements, the subsequent process will further increase the error of the workpiece, so that the sheet metal parts cannot be used, resulting in the scrapping of the workpiece. The stamping forming of the arc surface has higher requirements on the processing technology, because it is easy to produce gaps in the process of arc surface processing, and due to the continuous stamping process of the mold, the arc surface of the workpiece is not enough, and it is easy to produce ar...
