1. Parts Analysis Figure 1 shows the temperature sensor of the evaporator parts. The material is 2A02 aluminum plate with a material thickness of 0.5mm. Since the part needs to be vulcanized together with the evaporation plate, the surface quality and flatness are required to be high, and defects such as warpage, scratching, embossing, wrinkling, and cracking are not allowed. Since the product is in a small batch trial stage, the process is defined as: blanking-draw-cutting. First calculate the dimension of the part, draw the expanded view, and then calculate the amount of deformation of the part to determine whether it can be drawn at one time. It can be drawn at one time by calculation. The blanking size is 44mm×52mm, which is rounded up to increase the drawing coefficient of the corner.
