Embodiment Construction

[0016] Such as Figure 5 , 6 , 7, and 8, a dual-purpose mold for drawing and flanging includes a punch 11 and a die 20 that are opened and closed with each other, and at least one of the punch 11 and the die 20 is driven by a drive unit. The reciprocating motion is used to realize the opening and closing action. The cavity of the die 20 is stepped and the large end of the cavity faces downward. The edge of the punch 20 is provided with a detachable insert 111. When the When the insert 111 is mounted on the punch 11, the size of the punch 11 is adapted to the size of the large end of the cavity. When the insert 111 is removed, the size of the punch 11 is adapted to the size of the small end of the cavity. The periphery of the punch 11 is also provided with a first clamping plate 12 for cooperating with the end face of the die 20 to clamp the sheet material 30 to be processed. The direction is parallel to the mold opening direction, and the bottom of the first clamping plate 1...

Abstract

The invention belongs to the technical field of cold punching dies of pressure manufacturing process equipment, and particularly relates to a drawing and flanging two-purpose die, which comprises a convex die and a concave die, wherein the convex die and the concave die are arranged in a mutual opening and closing way, at least one of the convex die and the concave die is driven by a driving unit to do reciprocating movement so as to realize the opening and closing action, a concave cavity of the concave die is in a step shape, the large end of the concave die faces downwards, and the edge of the convex die is provided with a detachable embedding block. When the embedding block is arranged on the convex die, the size of the convex die corresponds to the size of the large end of the concave die; when the embedding block is detached, the size of the convex die corresponds to the size of the small end of the concave die. The drawing and flanging two-purpose die has the advantages that the drawing and flanging two-purpose die can be simultaneously used for the drawing process and the flanging process, the effect of one die with two purposes is realized, the trial cost is reduced, the cost investment of a trial die is reduced, and the casting pollution is reduced; meanwhile, the switching is convenient, the die replacement time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of cold stamping dies in pressure manufacturing process equipment, and in particular relates to a common die structure used for drawing and flanging in the trial production process of an outer cover of an automobile body. Background technique [0002] Prototype vehicle trial production is a very important link in the entire automobile development process. During the development process, the virtual engineering design is developed through various rapid development means to approach the process of mass production and meet the requirements of design verification experiments. A process of prototyping, such as the manufacture of rapid prototypes and the manufacture of soft mold parts. In the trial production stage, the average cost of stamping parts for each sample car is usually calculated at 100,000 RMB. Therefore, to reduce the development cost of prototype cars, it is necessary to start with the investment in...
