Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a side trimming structure for stamping dies to prevent lateral force. Background Technology

[0002] The existing side trimming anti-lateral force structure adds a guide plate between the side trimming insert and the lower die base to prevent lateral forces. However, in the current method, when side-cutting large scrap, the anti-lateral guide plate must avoid the scrap and cannot be placed close to the line of action, resulting in poor anti-lateral force performance. The specific description is as follows: When side trimming starts, the side trimming insert is subjected to force A in the direction of the arrow. When the insert is working, it opens in the direction of the arrow A, causing a deviation between the actual trimming and the theoretical trimming, and the boundary quality of the parts is unstable during production.

[0003] The applicant found through a search that Chinese patent document with publication number 203316555U disclosed on December 4, 2013, a trimming tool for a trimming mold. The upper mold base of the trimming mold is provided with a pressure core and an upper trimming tool, and the lower mold of the trimming mold is provided with a lower trimming tool. The cutting edge of the upper trimming tool used for vertical trimming is an inclined plane at an angle to the horizontal plane. This device also cannot solve the above-mentioned technical problem.

[0004] Therefore, in order to improve or solve at least one of the above problems, it is necessary to provide a side trimming anti-lateral force structure for stamping dies that can avoid the displacement of the side trimming insert due to force, which would lead to a reduction in trimming accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a side trimming anti-lateral force structure for stamping dies that can prevent the side trimming insert from being displaced by force, thus reducing the trimming accuracy.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a side trimming and anti-lateral force structure for stamping dies, including a pressure plate; a punch is provided on the pressure plate; a side trimming insert is provided at the bottom of the pressure plate; an anti-side block is provided on the side trimming insert; the anti-side block is connected to the pressure plate; and the side trimming insert abuts against the punch.

[0007] The bottom of the pressure device is provided with a limiting block; the limiting block is provided on both sides of the pressure device; an installation groove is provided between adjacent limiting blocks; the punch is provided in the installation groove.

[0008] The side-repairing insert abuts against the limiting block; a connecting groove is provided on the top surface of the side-repairing insert; the anti-side block is connected in the connecting groove.

[0009] The anti-side block includes a support block; a limiting block is provided on one side of the support block; the limiting block is connected to the pressure device.

[0010] The pressure feeder is provided with a guide block on the side near the side trimming insert; one end of the guide block abuts against the top surface of the side trimming insert; the other end of the guide block abuts against the limiting block.

[0011] The top surface of the side trimming block is provided with a protrusion; the limiting block abuts against the protrusion.

[0012] The punch includes a trimming section; one side of the trimming section abuts against the limiting block; the bottom surface of the trimming section abuts against the protrusion.

[0013] The beneficial effects of this application are as follows:

[0014] The side trimming punch of this application is mounted on the pressure plate, and the anti-side block is fixedly connected to the side trimming insert and can move together with the side trimming insert. Before the side trimming insert contacts the punch by 5mm, the anti-side block begins to contact the pressure plate. The bottom surface of the limit block begins to contact the top surface of the guide slide. The side trimming insert continues to move along the side trimming direction and begins side trimming. At this time, the bottom surface of the limit block has overlapped with the top surface of the guide slide by 5mm. At this time, a force B can be generated between the limit block and the guide slide, thereby offsetting the lateral force A of the limit block on the side trimming insert, reducing the outward expansion tendency of the side trimming insert, and ensuring stable punch boundary quality during production.
