Abstract：

The continuous forming process of automobile brake housing was mainly analyzed to formulate an advanced process that benchmarked its international advanced production technology, and according to the production process, the production die was processed and manufactured. In the early stage, the actual production results were predicted and guided to a certain extent by selecting reasonable stamping process parameters and applying numerical simulation, and the most suitable transitional drawing shape for this type of housing was designed in the simulation environment so as to formulate the appropriate process passes. Then, according to the process sequence, the multi-station progressive die used in the production was designed, including die base, guiding device, unloading device and ranging device and so on, the progressive die assembly drawing and part drawing of the housing were drawn, and the die was processed and assembled. Finally, through the actual production experiment, the housing products that were in accordance with the strength, structure size and other aspects were produced, and the benchmarking was completed with the advantages of domestic traditional technology and foreign advanced technology in the conclusion, which brought a guiding reference for the subsequent production of such housings.
