The punching device has the advantages of simple structure, convenient replacement of punching quantity by using the same group of dies, time and labor saving, work efficiency improvement and production cost reduction.
Description
Technical Field
The utility model relates to a die, in particular to a die capable of rapidly switching the number of punched holes.
Background
At present, holes in a metal plate are mostly punched by using a punching machine, wherein the punching mold comprises an upper mold base and a lower mold base, an upper fixing plate is fixed below the upper mold base, an upper discharging plate is arranged below the upper fixing plate, the upper discharging plate is connected to the upper fixing plate or the upper mold base through springs and equal-length bolts, a female mold is fixed on the lower mold base, and a plurality of punches connected to the upper fixing plate penetrate through the upper discharging plate and are matched with a plurality of corresponding punched holes in the female mold. The upper die holder is fixed on the slider of punching machine upper portion, and the die holder is fixed on the workstation, and the part is arranged on the die, and the punch cooperates with the punching a hole on the die to punch out the hole with the part when punching a hole, and the hole number on the part is the same with the number of punch. If the number of holes in the part changes, another set of dies needs to be replaced to ensure that the number of punches is the same as the number of holes required in the part. The defects are very troublesome, time-consuming, labor-consuming and low in working efficiency.
Disclosure of Invention
The utility model aims to provide the die capable of quickly switching the punching quantity, which has a simple structure, is convenient to replace the punching quantity by using the same group of dies, saves time and labor, improves the working efficiency and reduces the production cost.
The die for rapidly switching the punching quantity comprises an upper die holder and a lower die holder, wherein an upper fixing plate is fixed below the upper die holder, an upper discharging plate is arranged below the upper fixing plate, the upper discharging plate is connected to the upper fixing plate or the upper die holder through springs and equal-length bolts, a female die is fixed above the lower die holder, a plurality of punches connected to the upper fixing plate penetrate through the upper discharging plate and are matched with a plurality of corresponding punching holes on the female die, a sliding groove is formed in the upper end of each punch and is positioned on the upper fixing plate, a sliding base plate is inserted into each sliding groove, and one end of each sliding base plate is positioned outside.
The die for rapidly switching the number of punched holes is simple in structure, the die does not need to be replaced after the number of holes of the part to be punched is changed, and the die can be conveniently adjusted, so that time and labor are saved, the working efficiency is improved, and the production cost is reduced.

Detailed Description
As shown in fig. 1 and 2: the utility model relates to a die capable of rapidly switching the number of punched holes, which comprises an upper die holder 1 and a lower die holder 5, wherein an upper fixing plate 2 is fixed below the upper die holder 1, an upper stripper plate 3 is arranged below the upper fixing plate, the upper stripper plate 3 is connected to the upper fixing plate 2 or the upper die holder 1 through springs and equal-length bolts, a female die 4 is fixed on the lower die holder 5, and a plurality of punches 7 connected to the upper fixing plate 2 penetrate through the upper stripper plate 3 and are matched with a plurality of corresponding punched holes 10 on the female die 4. A sliding groove 9 is formed in the upper end of each punch 7 and located on the upper fixing plate 2, a sliding base plate 6 is inserted into each sliding groove 9, and one end of each sliding base plate 6 is located on the outer side.
As in fig. 1 and 2: when a plurality of punches 7 need to punch the component 8 at the same time, the sliding pad 6 at the upper end of the corresponding punch 7 can be inserted into the chute 9, the upper end of the punch 7 is abutted against the bottom surface of the sliding pad 6, the sliding pad 6 at the upper end of the punch which does not need to be punched is pulled out, and the upper end of the punch is separated, at this time, the required holes can be punched at the corresponding positions on the component 8, if the number and the positions of the holes on the component 8 are changed, the positions of the sliding pads 6 can be adjusted (pulled out or inserted in). The punching device has the advantages of simple structure, convenient replacement of punching quantity by using the same group of dies, time and labor saving, work efficiency improvement and production cost reduction.
