Further, a guide pillar is vertically arranged between the upper die plate and the supporting base, and the upper die plate is slidably mounted on the guide pillar.
Further, the bottom of the upper die plate is provided with a base plate, the top end of the punch is fixed to the bottom of the base plate in a threaded mode, and the base plate is installed on the guide pillar in a sliding mode.
Furthermore, the middle part of the top surface of the upper template is provided with a connecting hole connected with a piston rod of the air cylinder.
Furthermore, the support base and the lower template are both provided with discharge holes for punching the iron sheet after falling out in a penetrating manner, and the discharge holes and the punch are arranged coaxially.
Further, be provided with the cushion between support base and the pressfitting piece, the cushion is rectangular form, is located support base top bilateral symmetry sets up, support through the bolt fastening between base, cushion and the pressfitting piece, form and be used for holding the punching hole groove that the sheet metal component passed.
The utility model has the advantages that: the utility model discloses when punching a hole the operation to long banding sheet metal component, the front end dashes the aperture earlier, and the rear end dashes the macropore again, and the process is reasonable, can effectively reduce the impact resistance that the drift bore when punching a hole, prolongs the life of drift, reduces the plant equipment maintenance replacement cost.

Detailed Description
The invention will be described in detail with reference to the following drawings and specific embodiments:
as shown in fig. 1-5, the punching die for punching sheet metal parts of the present invention comprises an upper die plate 1 and a lower die plate 2 which are oppositely arranged from top to bottom, a punching assembly is arranged between the upper die plate 1 and the lower die plate 2, the punching assembly comprises a supporting base 3, a pressing block 4 arranged on the supporting base 3 and punches 5 vertically sliding and penetrating through the pressing block 4, the top ends of the punches 5 are fixedly connected with the upper die plate 1, the punches 5 are provided with two groups, each group has three punches, the punches are distributed in an isosceles triangle shape, the diameter of one group of punches 5 is smaller than that of the other group of punches 5, the two groups of punches 5 extend along the moving direction of the sheet metal part 6, the sheet metal part 6 penetrates between the supporting base 3 and the pressing block 4 from one end provided with the small-diameter punch 5, penetrates between the supporting base 3 and the pressing block 4 from one end provided with the large-diameter punch, the pressing block 4 is used for preventing the sheet metal part 6 from warping upwards when punching holes to cause uneven hole edges. When punching the operation to rectangular form sheet metal component, the front end is earlier with the drift 5 towards the aperture of minor diameter, and the rear end is again with the drift 5 towards the macropore of major diameter, and the process is reasonable, can effectively reduce the impact resistance that drift 5 bore when punching a hole, prolongs the life of drift 5, reduces the plant equipment maintenance replacement cost.
