Embodiment Construction

[0035] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0036] In order to overcome the problem of post-sequence positioning of shallow drawn parts and overcome its defects, the technical solution adopted by the present invention is: during the drawing process, positioning holes are punched out in the waste part of the product. figure 1 The drawing and punching mechanism shown is installed on a flat plane with a minimum diameter of φ40mm in the waste area. When the drawing process is nearly complete, the first Figure 4 and Figure 6 The shown punching concave-convex die punches out the positioning holes required by the subsequent sequence, and then Figure 5 The pressing sleeve and bushing shown in the figure compress the hole and the surrounding area and press out a certain shape stock, which can alleviate the deformation of the hole to a...

Abstract

The invention relates to a punching device for a drawing die and a plate positioning method. The punching device comprises a support (1), a punching female die (2), a lining (3), a punching male die (5) and a material pressing sleeve (6), wherein the punching female die (2) is arranged on the lower part of the support (1); the punching male die (5) is arranged on the upper part of the support (1); the punching female die (2) and the punching male die (5) above the punching female die (2) are matched in shape and used for punching; the lining (3) is arranged in the punching female die (2); the material pressing sleeve (6) is sleeved outside the punching male die (5); and the lining (3) and the material pressing sleeve (6) above the lining (3) are matched in shape and used for pressing shaped stock.

Description

technical field [0001] The invention relates to a drawing die structure, in particular to a punching device and a plate positioning method for the drawing die. Background technique [0002] With the rapid development of the automobile industry, each OEM has entered into all-round competition in terms of brand, service, quality, and cost. As the focus of investment in the production preparation process, how to improve the quality of parts, especially the surface quality of outer covers It has become the subject of competing research by various OEMs and mold factories. [0003] After large-scale stamping parts are drawn and formed, the positioning on the subsequent trimming die generally adopts surface positioning to achieve a good positioning effect, but some drawing depths are shallow and the positioning accuracy of the surface cannot meet the requirements. If the profile positioning is still used in the first trimming of the parts, many problems will occur, and the positio...
