Description

Technical Field

[0001] The utility model relates to the technical field of punching, in particular to a punching die which is easy to position. Background Art

[0002] At present, blanking dies play an indispensable role in the manufacturing industry. Their wide application and significant advantages make them an important tool in the field of metal sheet processing. However, there is no certain positioning mechanism in the process of blanking parts, which leads to part deformation and material waste. Therefore, a blanking die that is easy to position is needed for operation.

[0003] A precisely positioned blanking die is disclosed in the Chinese utility model patent application disclosure CN 105363883 A. This device, by adding a limit column structure, can prevent the lower die seat from moving too far downward and causing excessive wear of the blade at the end of the punch when the upper die seat and the lower die seat are blanking, thereby helping to extend the service life of the die. By adding limit blocks in the front and sides of the feeding direction, the accuracy of the position of the strip material when it is fed is guaranteed, thereby ensuring the reasonable utilization rate of the material. However, this type of blanking die is simple and fixed and is not convenient to disassemble, replace and install. In addition, there is no certain auxiliary discharge mechanism, which may cause the parts to be stuck in the groove after the blanking is completed, resulting in subsequent inability to operate.
