Embodiment Construction

[0034] refer to Figure 5 , at this time the cold stamping drawing die is in the mold closing state. The lower mold base 3 is provided with a convex mold 31, and the convex mold 31 is either integrally cast with the lower mold base 3, or assembled together after being molded separately. combine Figure 5 , Figure 8 , Figure 9 and Figure 10 Visible, with Figure 1 to Figure 4 The difference of the prior art shown in is that in this embodiment, as the guide slide mechanism between the upper die base 1 and the blank holder 2, the upper die guide plate 11 on the upper die base 1 is changed from the original upper die The two ends in the length direction of the seat 1 are transferred to both sides in the width direction, and correspondingly, the guide sliding surface 21 on the blank holder 2 is also transferred to both sides in the width direction of the blank holder 2; at the same time, as In the guide-sliding mechanism between the blank holder 2 and the punch 31, blank h...

Abstract

The invention provides a cold stamping drawing die which comprises an upper die base, a blank holder and a lower die base. A convex die is arranged on the lower die base. A gap is formed in the blank holder. A material supporting mechanism is arranged inside the gap and provided with a modeling part and a pressing-down part. A first spring is arranged below the material supporting mechanism so that the modeling part can be higher than the blank holder in the die sinking mode. A second spring is arranged on the upper die base. In the die assembling process, the second spring presses down the pressing-down part so that the modeling part and the blank ring can form a complete modeling face. According to the cold stamping drawing die, an operator can be more conveniently move stamping parts out of the cold stamping drawing die.

Description

technical field [0001] The invention relates to the field of stamping dies. Background technique [0002] The development of new models has a rigid demand for mold tooling, and mold is also the tooling with the largest investment in the production and manufacturing equipment of various automobile companies. For the design of stamping dies, full consideration should be given to stamping formability, operation convenience, safety, smooth discharge of workpieces and waste materials, and the cost of mold tooling should also be considered. At present, body stamping parts are mainly realized by cold stamping, and the forming process mainly includes drawing, trimming, flanging, shaping and other work contents. [0003] The cold stamping drawing die of prior art is as Figures 1 to 4 As shown, it mainly includes upper mold base 1, blank holder 2 and lower mold base 3. Such as figure 1 As shown in detail, the upper die guide plate 11 and the blank holder ring guide sliding surfac...
