Embodiment Construction

[0032] Combine below Figure 1 to Figure 7 , the present invention is further described:

[0033] Such as Figure 1-5 As shown, the embodiment of the present invention provides an upper die of a stamping die, which includes an upper die base 11 , an elastic element 12 , a guide pin 13 , a mounting plate 14 , a dowel 15 and a pressing core 16 . Wherein, the upper mold base 11 can be an integral casting, and its bottom (the bottom refers to the side for installing the elastic element 12 after the upper mold base 11 is manufactured) has a space for installing the elastic element 12, on which there is The installation part located between the binder core 1 and the space, the installation part can specifically adopt a plate-shaped structure that can be detachably installed with the upper die base 11 .

[0034] The mounting plate 14 is installed on the mounting portion, and there are generally multiple elastic elements 12, and the plurality of elastic elements 12 are installed bet...

Abstract

The invention relates to a stamping method of a stamping die. The stamping die comprises an upper die and a lower die, dowel bars (15), a mounting plate (14) and elastic elements (12) are arranged above a pressure core (16) of the upper die sequentially, one end of an air cylinder (23) of a stamped part pressing and limiting mechanism is fixed onto the side wall of a lower die seat (21) through an air cylinder fixing end (22), and the other end of the air cylinder (23) is connected with one end of a stamped part pressing lever (25) through an air cylinder connection bolt (24). The stamped part pressing lever (25) is connected with a lever support (27) through a pivot bolt (26), the lever support (27) is fixed to the top face of the lower die seat (21), and the other end of the stamped part pressing lever (25) is provided with a stamped part pressing portion with a U-shaped passage groove (251). One end of a positioning rod (29) is fixed to the top face of the lower die seat (21), the other end of the positioning rod (29) is inserted into the U-shaped passage groove (251), and the positioning rod (29) penetrates a positioning hole of a stamped part.

Description

technical field [0001] The invention relates to a die stamping method, in particular to a stamping die stamping method. Background technique [0002] With the rapid development of the automobile industry, the application of stamping dies has become more and more extensive. During the stamping process, the elastic elements installed in the upper die provide sufficient pressing force to prevent the movement of the sheet during the stamping process and cause the plate The problem of lower precision and lower quality of stamping parts. [0003] The currently commonly used stamping dies mainly include an upper die base, a side pin, a lower die base, a pressing core, a square spacer, an elastic element, a spring guide pin and a guide plate. Wherein the upper mold base is an integral casting structure, the side pin passes through the side wall of the upper mold base, and is fixed on the upper mold base through the fixing plate, and the side pin cooperates with the groove on the pr...
