Abstract

The invention provides a forming machining mold for a vehicle exhaust system thermally-insulated shield. The forming machining mold for the vehicle exhaust system thermally-insulated shield can solve the problem that material plates formed by one-time stamping are prone to crack. According to the technical scheme, the forming machining mold for the vehicle exhaust system thermally-insulated shield comprises an upper installing plate and a lower installing plate. The forming machining mold for the vehicle exhaust system thermally-insulated shield is characterized by comprising a pre-forming module and a forming module, and the pre-forming module and the forming module are both installed between the upper installing plate and the lower installing plate.

Description

technical field [0001] The invention relates to a forming processing die for an automobile exhaust system heat shield, which relates to the technical field of forming automobile parts, in particular to the stamping processing and forming field of automobile exhaust system parts, specifically a forming processing die for an automobile exhaust system heat shield. Background technique [0002] Process a kind of automobile exhaust system heat shield 50, see figure 1 , the traditional one-piece casting method is used for processing and forming. Because of the complex structure of the heat shield, the traditional one-piece casting method is not only difficult to form, but also has poor processing quality, low efficiency and high cost. In order to overcome the above problems, the heat shield is now divided into the left half shell 51 and the right half shell 52, which are formed and processed separately and then welded, and in order to improve the processing efficiency, integral st...
