Problems solved by technology
[0003] At present, it is necessary to process a hardware part for a mobile phone. The shape of the finished product is as follows Figure 12 As shown, including the part body, there is a lock screw hole on the part body, and many bumps are set around the lock screw hole. One end of the part body is provided with a bend, and the other end is also provided with multiple bends, one of which is bent to the same The body of the part is parallel, so the processing will be relatively complicated, and it cannot be bent and formed at one time. Moreover, the design standard of this part is high, and the existing forming process is difficult to meet the design standard of this part; therefore, a special-purpose is designed for this part. stamping process to solve the above problems

Embodiment
[0046] Example: such as figure 1 ~ Figure 13 As shown, a metal stamping process, the hardware includes a part body, the part body is provided with a locking screw hole, a circle of convex points is provided around the locking screw hole, a bending part is provided at one end of the part body, and a bending point is provided at the other end. There are several bending places and one of the plates is bent parallel to the part body. The stamping process includes the first die, the second die, the third die, the fourth die, the fifth die, the sixth die, the seventh die, the first die eighth mold, ninth mold and tenth mold;
[0047] Such as figure 1 As shown, the first mold includes a first stripping entry 103, a first blanking punch 102 arranged in the middle of the first stripping entry 103 and a first stripping punch 102 arranged below the first stripping entry 103 through and up and down. A feeding knife edge 104;
[0048] Such as figure 2 As shown, the second mold in...

The invention provides a stamping process for hardware. The stamping process comprises the following process steps of: punching, bending, bending and adjusting, bending by 90 degrees, bending by 135 degrees, bending by 180 degrees, forming salient points and the like. According to the stamping process, a material is treated through a series of processes, so that each structure therein is molded in place; and a high-precision product is obtained by pre-bending to meet the design standard. Compared with the traditional rapid bending in place, the stamping process has the advantages that the deformation is less, the accuracy is high, the reclassification for multiple shaping is not needed, the labor cost is reduced, the relative efficiency is relatively high, the cost is relatively low, and the practicability is high.
Description
technical field [0001] The invention relates to the field of mold processing, in particular to a stamping process of hardware parts. Background technique [0002] The stamping process is a metal processing method, which is based on the plastic deformation of the metal, using the mold and stamping equipment to exert pressure on the sheet, so that the sheet is plastically deformed or separated, so as to obtain a product with a certain shape, size and performance. parts (stampings). [0003] At present, it is necessary to process a hardware part for a mobile phone. The shape of the finished product is as follows Figure 12 As shown, including the part body, there is a lock screw hole on the part body, and many bumps are set around the lock screw hole. One end of the part body is provided with a bend, and the other end is also provided with multiple bends, one of which is bent to the same The body of the part is parallel, so the processing will be relatively complicated, and it...
