[0019] like Figure 1-4 As shown: a punching die for a vehicle frame straight connecting plate, comprising a punching upper die 1 and a punching lower die 2; a first station and a second station are arranged at the middle of the punching lower die 2; a first locating pin 25 and a plurality of second locating pins 26 are arranged at the first station; a third locating pin 27 is arranged at the second station.

[0020] The left and right sides of the punching lower die 2 are provided with grooves 21, the bottom wall of the groove 21 is provided with a plurality of guide pillars 22, and the side wall of the groove 21 is provided with a plurality of first guide plates 23 for positioning.

[0021] A first anti-side block 24 is provided in the middle of the punching lower die 2 and on both sides of the first and second positions to prevent rollover.

[0022] The left and right sides of the punching upper die 1 are provided with protrusions 11 matching with the grooves 21 , the top wall of the protrusion 11 is provided with a plurality of guide holes 12 matching with the guide pillars 22 , and the side wall of the protrusion 11 is provided with a plurality of second guide plates 13 matching with the first guide plates 23 .

[0023] A plurality of stripping plate guide pins 15 are arranged in the middle of the punching upper die 1 for stripping materials; a second anti-side block 14 cooperating with the first anti-side block 24 is arranged in the middle of the punching upper die 1 and on both sides of the stripping plate guide pins 15 .

[0024] Working principle: When in use, first place the blank of the vehicle frame straight connecting plate on the first station of the punching lower die 2, and position it through the first positioning pin 25 and the two second positioning pins 26; use the punching upper die 1 to perform the first punching process on the blank;

[0025] When the punching upper die 1 is used for punching again, another blank can be placed at the first station of the punching lower die 2, and the part processed at the first station can be placed at the second station of the punching lower die 2. The first punching of the part is positioned by two third positioning pins 27, and then the punching upper die 1 is used to perform the first punching of the blank and the second punching of the part processed at the first station. This realizes the merging of the punching contents of the mold and reduces the mold investment cost. It avoids various problems existing in the early stage in structure and improves the reliability and quality stability of the mold.
