Embodiment 1

[0078] This embodiment provides a deep-drawing die for deep-drawing ribbed parts, including a male die device, a female die device, and a cutting assembly for cutting a blank into a predetermined shape, such as Figure 5 , The ribbed part is the top cover 22 in this embodiment.

[0079] Such as figure 2 As shown, the male mold device is a lower mold device in this embodiment, comprising: a male mold base 7; , and the bead forming part 17 of the male mold, and the deep drawing forming part 16 of the male mold can be movably arranged on the male mold base 7 along the moving direction of the female mold base, and when there is no external force, the male mold deep drawing The forming part 16 is reset to the initial position under the action of the first reset structure; the male mold release plate 5 that can be movably arranged on the male mold base 7 along the moving direction of the female mold base, and when there is no external force, the The male mold release plate 5 can ...

Embodiment 2

[0093] This embodiment provides a method for deep drawing of a part with ribs, including a compacting step, a deep drawing step, and a bead pressing step. Specifically, on the same mold, the female mold device is driven to move to the pressing position, and the blank placed on the male mold device is pressed; the female mold device is driven to continue to move to the drawing position, and the blank is drawn into the preliminary processing without ribs. Parts; continue to drive the master mold device to move from the drawing position to the beading position, and perform beading on the pre-processed parts formed by deep drawing to form ribbed parts. In this embodiment, a cutting step is also included between the pressing step and the drawing step, the cutting step includes driving the master mold device on the same mold to move from the pressing position to the cutting position, and cutting the blank into the blank of a predetermined shape . The ribbed part in this embodiment ...

Abstract

The invention provides a deep-drawing die and a deep-drawing forming method for parts provided with ribs. The deep-drawing die comprises a male die device and a female die device; the male die devicecomprises a male die seat, a male die and a male die stripping plate; the male die comprises a male die deep-drawing forming part and a male die ribbing forming part; the male die deep-drawing formingpart can be movably arranged on the male die seat in the moving direction of a female die seat and can be restored to the initial position under the action of a first restoration structure without the external force; the male die stripping plate can be movably arranged on the male die seat in the moving direction of the female die seat and can be restored to the initial position under the actionof a second restoration structure without the external force; the female die device comprises a female die seat, a female die and a female die stripping plate; the female die comprises a female die deep-drawing forming part and a female die ribbing forming part; and the female die stripping plate is arranged on the female die seat. Materials are stressed to flow and are deformed evenly during forming, and bad phenomena such as corrugation, cracking and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a deep-drawing die and a method for drawing and forming parts with ribs. Background technique [0002] Deep drawing is a cold stamping process that uses a die to draw a flat blank or a semi-finished blank into an open hollow part. The shapes of the products that can be made by the deep drawing process are: cylindrical, stepped, spherical, conical, rectangular and other various irregular opening hollow parts. The basic principle of deep drawing is: during deep drawing, the blank holder first compresses the middle plate blank, and the punch moves downward, forcing the material (flange part) under the blank holder to undergo plastic deformation and flow into the gap between the punch and die to form the cylinder side. wall. The deformation of the deep-drawing material mainly occurs in the flange part. The process of deep-drawing deformation is essentially that the material at the f...
