Description

[0002] The mobile phone housing is one of the external structures of the mobile phone, and is made of materials such as metal, plastic, and glass. For the production of some metal mobile phone rear housings, the method of stamping and shaping followed by polishing and grinding is adopted. Since camera slots and flash slots need to be left on the rear housing, one-time stamping is likely to cause deformation of the metal raw material plate, resulting in a low qualified rate. Moreover, in order to prevent scratches during the transportation of the metal raw material plate, a protective film is mostly covered on the back. Before stamping, it is manually peeled off, and then the metal raw material plate is positioned and stamped. There are many manual operation processes, and the overall operation efficiency is low.

Another group of hydraulic rods 14 push the second shaping upper die 43 to descend. The second shaping upper die 43 and the second shaping lower die 42 stamp out the slots for installing the camera hole and the slot for installing the flash hole;

[0056] Step 4: The third group of suction cups 691 retracts and descends to adsorb the completely stamped mobile phone housing, and then advances to place the mobile phone housing in the subsequent material receiving and processing device for edge polishing;
