Abstract

The invention relates to a stamping and drawing die which comprises an upper die and a lower die matched with the upper die. A material pressing plate is arranged on an upper bottom plate of the upper die and located in the concentrated flowing position of stamping part panels of the upper bottom plate. The material pressing plate is provided with an ejector rod arranged vertically. The top end of the ejector rod is fixed to the material pressing plate. The bottom end of the ejector rod is suspended and is close to the edge of the lower die. A blank holder is arranged on the edge of the lower die. A swing wedge mechanism used for abutting against the ejector rod is arranged on the lower die and is close to the blank holder. In the process that the upper die and the lower die are assembled, the swing wedge mechanism abuts against the ejector rod. According to the stamping and drawing die, while the effect that stamping parts are not damaged due to pressing during normal production of the die is guaranteed, due to the fact that the upper material pressing plate is arranged in the over-concentrated flowing position of the stamping part panels, the stamping parts are formed in the compressed state, the flowing uniformity of materials is guaranteed, and the problem that the stamping parts are wrinkled is well solved.

Description

technical field [0001] The invention relates to a die, in particular to a stamping and drawing die. Background technique [0002] In the drawing process of stamping parts, for places where the surface is more complicated and difficult to form, when the stamping parts are pressed, the board is prone to wrinkling or cracking, and there will also be a drawing board that is not in place These problems will greatly reduce the quality of drawing, and will also increase the workload of on-site commissioning personnel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stamping and drawing die, which can ensure normal production and avoid crushing stamping parts while solving the problem of stamping parts wrinkling. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a stamping and drawing die, comprising an upper die and a lower die matched with the upp...
