Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to a mold edge replacement structure. Background Technology

[0002] Die blanking is a key process in metal stamping. It refers to the process of applying pressure to the edge of the blank through a blanking device (such as a blanking ring) during the stamping process to restrict material flow, prevent defects such as wrinkling and cracking in the stamped parts, and ensure forming accuracy and quality. In forming processes such as deep drawing and bending, the edge of the blank is prone to instability and wrinkling due to tangential compressive stress. Blanking force can suppress material buckling.

[0003] In actual manufacturing scenarios, when the edge structures of two products differ, traditional manufacturing methods often require changing to a suitable mold based on the specific shape of the product's edge. For example, if one product has a stepped edge structure and the other has a beveled edge structure, due to the specificity of the mold structure, the company needs to prepare two sets of dedicated molds to meet the needs of alternating production. This model requires double the mold purchase cost, thereby increasing the actual production cost. Utility Model Content

[0004] The purpose of this invention is to provide a mold edge-changing structure, aiming to solve the problem that in actual processing scenarios, when the edge structures of two products differ, traditional manufacturing methods often require changing to a suitable mold based on the specific shape of the product's edge. For example, if one product has a stepped edge structure and another has a beveled edge structure, due to the specificity of the mold structure, the company needs to prepare two sets of dedicated molds to meet the needs of alternating production. This model requires double the mold purchase cost, thus increasing the actual production cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold pressing edge replacement structure, including a lower mold, a pressing edge component installed on the surface of the lower mold, the top of the pressing edge component being connected to the bottom of an upper mold, and a punch head being movably installed in a through hole at the top of the upper mold;

[0006] Two side strips are respectively provided on both sides of the pressing component. The bottom of each side strip is locked to the pressing component by a bolt threaded connection. The top of each side strip is locked to the outer wall of the upper mold by a first bolt threaded connection. A set of second bolts is threaded downward near the end corner of the pressing component, and the second bolts penetrate the pressing component and are threaded to the lower mold threaded connection.

[0007] To make the connection between the upper end of the side strip and the pressing edge component more flexible, as a mold pressing edge replacement structure of this utility model, preferably, the upper end of the side strip is provided with a longitudinal through hole, and the area to which the longitudinal through hole belongs is located on one side of the pressing edge component, corresponding to the first bolt passing through the longitudinal through hole and docking with the pressing edge component.

[0008] In order to ensure that the pressing component can be firmly installed on the lower mold, as a mold pressing replacement structure of this utility model, preferably, a third bolt is provided on one side of each second bolt, and the third bolt thread passes through the pressing component and connects with the lower mold.

[0009] As a mold pressing edge replacement structure of the present invention, preferably, the pressing edge component includes a first pressing edge plate, and a second step is provided on the outer wall of the first pressing edge plate near the central through hole. A first step is also provided on the outer wall of the first pressing edge plate around the second step, and the height of the first step is higher than the height of the second step.

[0010] As a mold pressing edge replacement structure of the present invention, preferably, the pressing edge component includes a second pressing edge plate, and a third step is provided on the outer wall of the second pressing edge plate near the central through hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When it is necessary to replace the blank holder component, the two first bolts on the side strip can be removed, thus detaching the upper mold from the blank holder component. Next, the second and third bolts are removed sequentially, thereby releasing the fixing structure between the blank holder component and the lower mold. At this point, the appropriate first or second blank holder plate can be installed between the lower and upper molds using the side strip, first bolts, second bolts, and third bolts, as needed. This allows for quick replacement of the blank holder component as required. Thus, one set of lower and upper molds can be used to accommodate two different blank holder components, thereby saving production costs. Attached Figure Description
