The invention discloses a manufacturing method of a camping part. The method comprises the steps of performing stamping to obtain a first semifinished product, wherein the first semifinished product is provided with a positioning hole; performing first-time trimming on the first semifinished product along a first-time trimming line to obtain a second semifinished product, wherein the positioning hole is formed between the first-time trimming line and a second-time trimming line; performing second-time trimming on the second semifinished product along the second-time trimming line to obtain a workpiece with no positioning hole. According to the manufacturing method of the stamping piece, first-time trimming is performed on the first semifinished product along the first-time trimming line, and the second semifinished product with the positioning hole is obtained, so that second-time trimming is performed on the second semifinished product along the second-time trimming line, and a finalneeded workpiece is obtained. In the stamping manufacturing process, when second-time trimming is performed through the positioning hole, accurate positioning is provided for the stamping piece, and the stamping accuracy of the stamping piece is improved.
Description
technical field [0001] The technical field of stamping of the present invention, in particular, relates to a method for manufacturing a stamping part and a semi-finished product of the stamping part. Background technique [0002] In related technologies, in the field of machinery, especially in the direction of vehicles, the use of stamping parts is very common. However, for some relatively flat stamping parts (for example: door outer panels, machine covers, etc.), when the stamping and trimming are completed and the next process is carried out, errors will be caused by inaccurate positioning of the stamping parts, thereby reducing the quality of the product. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a method for manufacturing a stamping part, which can realize precise positioning of the stamping part during the stamping process an...
