Forming die for expanded metal meshes for supplementary restraint systems

Abstract

A forming die for expanded metal meshes for supplementary restraint systems comprises an upper die body and a lower die body. Inner guide posts and inner guide sleeves which are in guide fit are arranged between the upper die body and the lower die body correspondingly. The upper die body comprises an upper die base, an upper die plate and a stripper plate, the upper die plate is fixed to the bottom of the upper die base, the striper plate is relatively spaced from the upper die plate and is connected below the upper die plate in a hung mode through elastic connecting pieces arranged at the four corners, and a punching pin set and a cuter set are sequentially fixed to the bottom of the upper die plate in a front and back mode in the steel plate feeding direction. The lower die body comprises a lower die base and a lower die plate fixed to the top of the lower die base. When the forming die for expanded metal meshes for supplementary restraint systems is used for machining steel plates,punching and cutting forming of steel plates can be achieved on one punching machine, and machining and forming efficiency is high. The problem that when materials are transferred and positioned again, unqualified products and scrapped products are generated due to positioning reference deviation is avoided, and thus the percent of pass of products is effectively increased.

Description

technical field [0001] The invention relates to the field of airbag filter screen processing, in particular to a steel mesh forming die for an airbag. Background technique [0002] Expanded mesh is widely used as a screen protector in the airbag field. At present, the forming process of expanded metal mesh requires two processes, namely punching and cutting. Firstly, the whole plate is made into a perforated plate on a punching machine, and then the material is transferred to a cutting machine for cutting to achieve the required shape of the steel plate for the airbag. However, when the material is transferred, not only the processing efficiency is low, but also when the material is repositioned on the cutting machine after the transfer, it is easy to cause unqualified products and scrapped products due to the deviation of the positioning reference. Contents of the invention [0003] In view of the above problems, the present invention provides an expanded metal mold for...
