Specifically, the lower die is further provided with a lower die plate located below the material pressing plate, and the material supporting block is embedded into the lower die plate.

Furthermore, a fool-proof notch is arranged on one corner of the material supporting block.

Furthermore, a pressing block used for pressing the material supporting block is fixed on the lower template, and a notch avoiding the pressing block is formed in the punch.

Further, the bottom of the punch is provided with a hollow structure.

The utility model discloses technical scheme's beneficial effect is:

the utility model discloses a set up a plurality of location backer on profile modeling locating component, let the similar product that the processing position is the same can all accomplish processing with one set of die, saved the die sinking cost.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 7, the utility model discloses a common type punch die, including lower mould and last mould, the lower mould is including the support piece 21 that has blanking hole 211 and the profile modeling locating component 22 that is located support piece 21 one side, it has just to the drift 31 of blanking hole 211 and surrounds the pressure flitch 32 that can float in the drift 31 outside to go up the mould, be equipped with first location backer 221 and second location backer 222 on the profile modeling locating component 22, first location backer 221 is the spill structure and has the last domatic 2211 of slant support piece 21 top, be equipped with two first reference columns 2212 on the last domatic 2211, second location backer 222 has the side domatic 2221 of slant side, be equipped with two second reference columns 2222 on the side domatic 2221. The upper slope surface 2211 and the side slope surface 2221 are for adapting to the shape of the workpiece, the first positioning column 2212 and the second positioning column 2222 can be positioned by using a hole position on a non-punching part of the workpiece, and the number of the first positioning column 2212 and the second positioning column 2222 can be increased or decreased according to the use requirement. In actual work, the a workpiece 1a positions the two corresponding fixing holes 12 by means of the first positioning columns 2212 on the first positioning backer 221, the cut-off part 11 is positioned on the material supporting block 21, then the die is closed, the material plate 32 presses the material around the cut-off part 11 of the a workpiece 1a, and then the punch 31 cuts down into the blanking hole 211 to complete the die cutting; when the B workpiece 1B is machined, only the positioning position at the upper part is replaced by the second positioning post 2222 on the second positioning backer 222, and the second positioning post 2222 positions the two corresponding fixing holes 12 on the B workpiece 1B, and then the die assembly is performed in the above manner. The utility model discloses a set up a plurality of location backer 221, 222 on profile modeling locating component, let the similar product that the processing position is the same can all accomplish processing with one set of die, saved the die sinking cost.

As shown in fig. 3, 6 and 7, the lower die further has a lower die plate 23 located below the material pressing plate 32, and the carrier block 21 is embedded in the lower die plate 23. The supporting block 21 can be a replaceable part, and only part of the supporting block 21 needs to be modified when the mould is changed, so that the research and development investment is saved.

As shown in fig. 5, a fool-proof notch 212 is provided on one corner of the carrier block 21. Because the installation direction of the supporting block 21 is fixed, and the direction needs to be identified when the lower template 23 is installed, the judgment can be accelerated by the fool-proof notch 212, and the misplacement can be prevented.

As shown in fig. 3, 4, 6 and 7, a pressing block 24 for pressing the supporting block 21 is further fixed on the lower template 23, and the punch 31 is provided with a notch 311 for avoiding the pressing block 24. The position of the pressing block 24 does not interfere with blanking, but the position of the material supporting block 21 can be fixed, so that the phenomenon that the punching precision is influenced due to looseness of the material supporting block is avoided, and the action of the punch 31 is not hindered.

As shown in fig. 4, the bottom of the punch 31 has a hollow structure 312. The outside of the hollow structure 312 is the part of the punch 31 contacting with the material, and the design can concentrate the shearing force of the punch 31 on the cut surface, so that the material section is smoother.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
