Mechanism capable of achieving continuous trimming of aluminum plate die

Abstract

The invention provides a mechanism capable of achieving continuous trimming of an aluminum plate die. The mechanism at least comprises a rotating waste cutter, an upper die trimming cutter, a lower die waste cutter and a lower die ejecting block. The rotating waste cutter is installed on the lower surface of the upper die trimming cutter through a rotating shaft. A spring is vertically arranged on the top face of a cutter tail of the rotating waste cutter, and the top face of the spring is connected with the lower surface of the upper die trimming cutter. The upper die trimming cutter is installed on an upper die, and a trimming cutting edge of the upper die trimming cutter is attached to a cutter head of the rotating waste cutter. The lower die waste cutter and the lower die ejecting block are installed on the top face of a lower die, and the lower die ejecting block is located under the cutter tail of the rotating waste cutter. The mechanism capable of achieving continuous trimming of the aluminum plate die is reasonable in design, simple and compact in structure, stable in running and capable of achieving continuous trimming and reducing aluminum plate trimming fragments, and therefore the limitation on the aspect of structure design of the kind of dies is reduced, the die stability is improved, and the manufacturing cost of parts is reduced.

Description

Technical field [0001] The invention relates to a mold trimming mechanism, in particular to a mechanism capable of realizing continuous trimming of aluminum plate molds. Background technique [0002] At present, the application of aluminum plates on car bodies is becoming more and more extensive, and the output of aluminum plate molds is also increasing, which also promotes the continuous improvement of aluminum plate mold technology. In the steel plate mold, the trimming has a step difference in the scrap cutter section, and the trimming is not continuous. When applied to the aluminum plate trimming, it is easy to generate debris. Therefore, the continuity of the trimming must be ensured in the aluminum plate mold. Complete cutting of waste. [0003] At present, continuous trimming of aluminum plates is mostly achieved by floating scrap knives. The cutting of the scrap part is achieved by the scrap knives of the lower die contacting the floating knives of the upper die, pushing t...

AI Technical Summary

Problems solved by technology

[0003] At present, the continuous trimming of aluminum plates is mostly realized by floating waste knives. The cutting of the waste part is through the waste knife of the lower mold contacting the floating knife of the upper mold. Partial cutting, because both the scrap knife and the floating knife have an irregular surface structure, they are easily damaged under the impact of high stamping times, which affects the yield rate and production efficiency, and its structure is more duplicated, and the space is larger, and the structural design will have a certain impact. limitations
