Abstract
The high-low punching die comprises an upper die base and a lower die base, wherein an upper base plate is installed on the lower side of the upper die base, an upper clamping plate is installed on the lower portion of the upper base plate, a stripper plate is installed on the lower side of the upper clamping plate, countersunk holes with different depths are formed in the lower side of the upper base plate, and the upper end of a punch is installed in the countersunk holes; the lower die base is provided with a lower backing plate, and the upper part of the lower backing plate is provided with a lower die plate. The utility model discloses a height is towards punching die, the counter sink through the different degree of depth realizes the poor installation of the punch head height section that punches a hole, and the drift can not contact the product simultaneously because the section is poor the reason among the stamping process, reduces the blanking power and the stress of punching press simultaneously, and original mould relatively has reduced mould and cost of labor, can also guarantee the plane degree of product, because the drift quantity of punching press simultaneously reduces, and noise can greatly reduced, and rupture phenomenon can not appear in the drift yet.
Description
Technical Field
The utility model relates to the technical field of molds.
Background
The existing punching die can bear the side punching force required by punching only in a mode of increasing the die set number because the punching force is too large when punching the parts with a plurality of holes; and a large number of punches are simultaneously used for making holes, so that the punches are easy to break due to stress, the flatness of a product is not good, and noise pollution is too large.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned problem that current porous drift mould exists, the utility model provides a height dashes towards hole mould.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the high-low punching die comprises an upper die holder 1 and a lower die holder 9, wherein an upper base plate 4 is arranged on the lower side of the upper die holder 1, an upper clamping plate 5 is arranged on the lower portion of the upper base plate 4, a stripper plate 6 is arranged on the lower side of the upper clamping plate 5, countersunk holes 15 with different depths are formed in the lower side of the upper base plate 4, and the upper end of a punch 12 is arranged in the countersunk hole 15; the lower die base 9 is provided with a lower cushion plate 8, and the upper part of the lower cushion plate 8 is provided with a lower die plate 7.
An upper back plate 3 is arranged at the front and the rear of the lower side of the upper die base 1, an upper backing plate 4 is fixed on the upper back plate 3, and a high-strength rubber 2 is arranged between the upper backing plate 4 and the upper die base 1.
And a stroke limiting block 13 and an outer guide pillar 14 are arranged between the upper die holder 1 and the lower die holder 9.
The lower side of the lower die base 9 is provided with a lower cushion block 10, and the lower part of the lower cushion block 10 is connected with a lower supporting plate 11.
The utility model discloses a height is towards punching die, the counter sink through the different degree of depth realizes the poor installation of the punch head height section that punches a hole, and the drift can not contact the product simultaneously because the section is poor the reason among the stamping process, reduces the blanking power and the stress of punching press simultaneously, and original mould relatively has reduced mould and cost of labor, can also guarantee the plane degree of product, because the drift quantity of punching press simultaneously reduces, and noise can greatly reduced, and rupture phenomenon can not appear in the drift yet.
Drawings
Fig. 1 is a top view structural diagram of the high-low punching die of the present invention.
Fig. 2 is a left side view structural diagram of the high-low punching die of the present invention.
In the figure: 1. the die comprises an upper die base, 2 parts of a high-strength rubber, 3 parts of an upper back plate, 4 parts of an upper backing plate, 5 parts of an upper clamping plate, 6 parts of a stripper plate, 7 parts of a lower die plate, 8 parts of a lower backing plate, 9 parts of a lower die base, 10 parts of a lower backing block, 11 parts of a lower supporting plate, 12 parts of a punch, 13 parts of a stroke limiting block, 14 parts of an outer guide pillar, 15 parts of a counter bore.
Detailed Description
The structure of the high-low punching die of the utility model is shown in fig. 1 and fig. 2, and comprises an upper die base 1 and a lower die base 9, wherein a lower cushion block 10 is arranged at the lower side of the lower die base 9, the lower part of the lower cushion block 10 is connected with a lower supporting plate 11, an upper padding plate 4 is arranged at the lower side of the upper die base 1, an upper clamping plate 5 is arranged at the lower part of the upper padding plate 4, a stripper plate 6 is arranged at the lower side of the upper clamping plate 5, counter bores 15 with different depths are arranged at the lower side of the upper padding plate 4, and; the lower die base 9 is provided with a lower cushion plate 8, and the upper part of the lower cushion plate 8 is provided with a lower die plate 7. An upper back plate 3 is arranged at the front and the rear of the lower side of the upper die holder 1, an upper backing plate 4 is fixed on the upper back plate 3, and a high-strength rubber 2 is arranged between the upper backing plate 4 and the upper die holder 1. A stroke limiting block 13 and an outer guide post 14 are arranged between the upper die holder 1 and the lower die holder 9.
The operation process of the die comprises the following steps: the method comprises the steps of raw material feeding, punching and stripping, and is a complete process, wherein back countersunk heads 15 with different depths are finely machined on the back surface of an upper padding plate 4 of a punching die, so that an upper die punching punch protrudes out to have different heights of a stripping plate 6, a lower die plate 7 of the punching die is installed on a corresponding lower die, and when the die runs, the upper die punching punch 12 can contact a product in batches due to different protruding heights to be inserted into the punching die and complete a punching process, so that the number of punched holes at each time is reduced, the noise and stress can be reduced simultaneously, the punch is not easy to bend, and the number of the die can be reduced properly. The guiding device comprises an outer guide post 14 and a guide sleeve, and the upper die base 1 moves up and down along the guide post.
