Description
Technical Field
The utility model relates to a stamping die's field, concretely relates to bits structure is prevented jumping by punching press suitable for regular appearance.
Background
In the stamping process, when the shape of the scrap is more regular, the periphery of the punched scrap is uniformly contracted towards the center and has a uniform gap with the cutting edge of the female die, so that the contact area between the scrap and the side wall of the female die is reduced, the gripping force is reduced, and the scrap is easily jumped out of the female die, and the occurrence rate of personal accidents is increased due to the scrap cleaning; on the other hand, the product is scrapped, the mold is damaged, and other serious quality and safety problems are caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a bits structure is prevented jumping by punching press suitable for regular appearance, effectively solved the material area and jumped out the problem of die easily at the bits material that the punching press in-process produced.
The purpose of the utility model is accomplished through following technical scheme: the punching scrap-jumping-prevention structure suitable for the regular shape comprises a lower cutter opening component A and a lower cutter opening component B, wherein female dies of the lower cutter opening component A and the lower cutter opening component B are mutually attached to form a lower cutter opening, a material belt is arranged right above the lower cutter opening and is punched downwards through an upper punch to generate scrap materials, scrap-jumping-prevention grooves are formed in the positions of the female die cutting edges of the lower cutter opening component A and the lower cutter opening component B, and the scrap-jumping-prevention grooves are inclined towards the outer side of the female die cutting edge, so that scrap-jumping-prevention ribs are formed in the positions, corresponding to the scrap-jumping; the lower knife edge gradually expands outwards from top to bottom to form a horn-shaped blanking groove for discharging scraps.
According to the preferable technical scheme, two chip-jumping-preventing grooves are formed in the female die cutting edge of the lower cutting edge component A, and two chip-jumping-preventing grooves are also formed in the corresponding positions of the lower cutting edge component B.
As a further technical scheme, the depth of the chip-jumping prevention groove is adjusted according to the thickness of the material belt.
The utility model has the advantages that: the scraps are effectively prevented from jumping out of the lower knife edge, and the maintenance cost of the die is reduced; the inclined chip-jumping-preventing groove design can avoid the phenomenon of side turning and can effectively prevent the generation of a piston effect; the chip-jumping prevention structure is suitable for structures with all regular shapes, and the depth of the chip-jumping prevention groove is only required to be properly adjusted according to the thickness of the material belt.

Description of reference numerals: the punching machine comprises an upper punch 1, a material belt 2, a lower knife edge assembly A3, a lower knife edge assembly B4, chips 5, a chip jumping prevention groove 6, a blanking groove 7 and a chip jumping prevention rib 8.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in fig. 1, the punching scrap-jumping-prevention structure suitable for regular shapes comprises a lower cutter edge assembly A3 and a lower cutter edge assembly B4, wherein female dies of the lower cutter edge assembly A3 and the lower cutter edge assembly B4 are mutually attached to form a lower cutter edge, a material belt 2 is arranged right above the lower cutter edge and is punched downwards by an upper punch 1 to generate scraps 5 (shown in fig. 2), scrap-jumping-prevention grooves 6 are formed in the female die cutter edges of the lower cutter edge assembly A3 and the lower cutter edge assembly B4, and the scrap-jumping-prevention grooves 6 are inclined towards the outer side of the female die cutter edge, so that scrap-jumping-prevention ribs 8 are formed in positions, corresponding to the scrap-jumping-prevention; as shown in fig. 5, the lower knife edge gradually expands from top to bottom to form a trumpet-shaped charging chute 7 for discharging the chips 5; as shown in fig. 4, two chip-jumping-preventing grooves 6 are formed at the die cutting edge of the lower cutting edge assembly a3, and two chip-jumping-preventing grooves 6 are also formed at corresponding positions on the lower cutting edge assembly B4. Preferably, the depth of the chip-jumping prevention groove 6 is adjusted according to the thickness of the material belt 2, so that the chip-jumping prevention groove 6 is suitable for all the chips 5 with regular shapes.
The utility model discloses a theory of operation: as shown in fig. 1, during stamping, the upper punch 1 descends to cooperate with the lower cutting edge assembly a3 and the lower cutting edge assembly B4 to cut the material belt 2 to generate scrap 5 (as shown in fig. 2), under the action of the scrap jumping prevention groove 6, the scrap 5 can form a scrap jumping prevention rib 8 (as shown in fig. 3), under the action of the scrap jumping prevention rib 8, a large biting force can be generated between the scrap 5 and the side wall of the lower cutting edge, and no inclination phenomenon occurs, so that the scrap 5 smoothly passes through the effective cutting edge, reaches the chute 7 of the lower cutting edge (because the chute 7 is horn-shaped, the scrap 5 cannot be stuck in the chute), and is discharged downwards.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
