Abstract

The invention provides a shaping die for an automobile exhaust system shell product. The shaping die for the automobile exhaust system shell product comprises an upper die base and a lower die base. Astripper plate is arranged under the upper die base, side shaping slotting tools are arranged on two sides of the upper die base, and a side shaping puncher chip is arranged under the stripper plate.The lower die base is provided with a side shaping block, the side shaping block is located under the side shaping puncher chip and matched with the side shaping puncher chip, side shaping sliding blocks are arranged on two sides of the side shaping block, and the side shaping sliding blocks and the side shaping slotting tools can move relatively. Compared with common shaping dies, the shaping die for the automobile exhaust system shell product is provided with movable sliding blocks, is convenient to maintain, achieves convenient and safe operation due to adjustability, and meets various machining conditions. The shaping sliding blocks are installed on the movable sliding blocks, and thus R-angle springback and material stacking occurring due to the fact that parts are in arc shapes andare provided with no reinforcing ribs can be avoided. Otherwise, three dies need to be produced, and manpower and material resources are wasted.

Description

technical field [0001] The invention relates to a plastic mold for automobile exhaust system shell products. Background technique [0002] Stamping processing is a production technology that uses the power of conventional or special stamping equipment to directly stamp the sheet or strip in the mold to be deformed and deformed, so as to obtain product parts with a certain shape, size and performance required by the drawings. Sheet metal, mold and equipment are the three elements of stamping processing. According to the stamping processing temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineering technology. Forming processing is a...
