Embodiment Construction

[0038] Next, the detailed structure, advantages and beneficial effects of the compound mold for simulating the continuous stamping forming characteristics of stamping parts according to the present invention will be described according to the accompanying drawings.

[0039] figure 1 It is a front cross-sectional view of a composite mold (hereinafter referred to as "die") for simulating the continuous stamping forming characteristics of stamping parts according to the present invention. Such as figure 1 As shown, the mold of the present invention has: the male and female mold adapter 1 connected with the main oil cylinder piston of the stamping machine (not shown); 1. A convex and concave mold body 20 with a convex and concave mold through hole 20a fixed on the convex and concave mold base 4;

[0040] Such as figure 1 As shown, the mold of the present invention also has a die part A and a blank holder part Y. The die part A includes a die body 19, a partial punch mount 10 mou...

Abstract

The invention discloses a compound die for simulating continuous drawing characteristics of stamped parts. The compound die is provided with a punch-die adapter (1), a punch-die part (T), and a local terrace die part (J), wherein the punch-die part comprises a punch-die base (4) and a punch-die body (20); and the local terrace die part (J) comprises a local terrace die body (12) and a local terrace die base (15), and is also provided with a die part (A) and a blank holder part (Y), a plurality of blank holder heating pipes (6) and at least one blank holder thermocouples (22) are arranged on the blank holder part, a plurality of punch-die heating pipes (7) and at least one two punch-die thermocouples (23) are arranged on the punch-die part, a plurality of die heating pipes (8) and at least one two die thermocouples (18) are arranged on the die part, and a plurality of local terrace die heating pipes (14) and at least one local terrace die thermocouple (13) are arranged on the local terrace die part. The compound die can reproduce the temperature rise state of the compound die after the stamped parts are continuously and rapidly heated, and can research the formation characteristic law of drawing and bulging of the stamped parts.

Description

technical field [0001] The invention relates to a mold, in particular to a composite mold for metal plastic processing which can be used to investigate the temperature rise of the mold and the deformation characteristics of the steel plate during continuous and rapid stamping of stamping parts for automobiles, and the influence of stamping process parameters on the forming process. Background technique [0002] In recent years, in order to improve market competitiveness, some domestic automobile manufacturers have introduced fast stamping production lines in the production of automotive stamping parts such as cover parts. The production frequency has nearly doubled and the stamping speed has been greatly increased. The parts that can be produced normally on the stamping line have the problem of a significant increase in the scrap rate on this fast line. [0003] In addition, this phenomenon often occurs in the production of automotive panels: a certain automotive panel is no...
