Split wedge mechanism

Abstract

The invention discloses a split type wedge mechanism. The split type wedge mechanism comprises a sliding block and a lower driving base, wherein the sliding block is in sliding connection with the lower driving base. The split type wedge mechanism further comprises an upper base, sliding guiding plates and nitrogen spring assemblies, wherein the number of the sliding guiding plates is at least two, every two adjacent sliding guiding plates are connected through a connecting limiting block, a sliding groove is formed between every two adjacent sliding guiding plates, each nitrogen spring assembly is installed in the corresponding sliding groove in a slidable manner, the bottom of each nitrogen spring assembly is fixedly connected with the top of the corresponding sliding block, the sliding guiding plates are fixedly installed at the bottom of the upper base, and operation holes formed corresponding to the nitrogen spring assemblies one to one are formed in the upper base. With the split type wedge mechanism, the phenomenon that machining cannot be carried out with a tool because of structural depth, slope angle and the like can be avoided, parts can be more universal and more convenient to maintain and replace, component structures are optimized, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a wedge mechanism, in particular to a split wedge mechanism. Background technique [0002] At present, automobile stamping parts are mainly realized by cold stamping. The forming process mainly includes drawing, trimming and punching, shaping, side trimming, side punching, side shaping, etc. For larger stamping parts, the side trimming , Side punching, and side shaping are mainly realized through a large wedge mechanism. In order to ensure the precise, stable and safe movement of the wedge mechanism, a guide slider and safety bolt parts are usually designed in the wedge slider, and a corresponding guide slide surface and safety surface are designed on the upper die base. [0003] figure 1 is the axonometric drawing of the wedge mechanism commonly used in the prior art, figure 2 It is a schematic diagram of the structure of the wedge mechanism assembled on the upper die base, combined with figure 1 and figure 2 , the guid...
