Description

Punching die

Technical Field

The utility model relates to a mould punching press technical field, concretely relates to cut-out press.

Background

At present, all the product is scrapped or is drilled with the drilling machine usually, and the loss of scrapping is big, and the hole position that the drilling machine bored is inaccurate, and the size in hole is also not unified, can cause very big puzzlement for the equipment, and leaks easily and punch, even partial product reworking handles, nevertheless still can scrap because the size is poor too far, causes the punching press cost height of product a lot.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a punching die, punching die simple structure, the processing cost is low, can guarantee to make the product of doing over again qualified, the expense of greatly reduced punching press production.

The utility model discloses a concrete technical scheme does:

the utility model provides a punching die, includes upper die portion, lower die portion and is used for measuring the outer spacing post of distance between upper die portion and the lower die portion, goes up the mould position on lower die portion, and is equipped with outer spacing post between the two, the below of upper die portion be equipped with the drift, be provided with elastic construction on the drift, lower die portion on be equipped with and punch a hole with the drift of mutually supporting, when the drift downstream when punching a hole, can compress elastic construction.

Furthermore, at least 1 positioning pin is arranged between the upper die part and the lower die part, and the upper die part can move up and down relative to the lower die part through the positioning pin.

Furthermore, the height of the elastic structure is not less than that of the outer limiting column.

Furthermore, the elastic structure is a high-strength rubber.

The upper die part comprises an upper die plate, a clamping plate connected with the upper die plate is further arranged below the upper die plate, and the punch is connected with the clamping plate.

Furthermore, the clamping plate is provided with a through hole, and the punch is connected with the upper die plate through the through hole.

Furthermore, the elastic structure is connected with the clamping plate.

The lower die part comprises a lower template, and the lower end of the positioning pin is positioned in the lower template and fixedly connected with the lower template.

Furthermore, the height of the positioning pin is greater than that of the outer limiting column.

The utility model discloses a beneficial achievement is: through using the utility model provides a cut-out press can carry out secondary operation to the semi-manufactured goods that leak and punch, has reduced disability rate and manufacturing cost, and does not exert an influence to the product quality.

Note: 1, mounting a template; 2, punching; 3, clamping plates; 4, high-tenacity glue; 5, preparing a product; 6, lower template; 7 positioning pins.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1

As shown in fig. 1, the utility model provides a punching die, constitute including last mould portion and lower mould portion, last mould portion be located lower mould portion on, be provided with 1 at least locating pin 7 between the two, last mould portion can move from top to bottom through locating pin 7.

The upper die part comprises an upper template 1 and a punch 2, and the punch 2 is arranged below the upper template 2 and is vertically connected with the upper template 1. A clamping plate 3 connected with the upper template 1 is further arranged below the upper template 1, and a through hole is formed in the clamping plate 3. The punch 2 is fixedly connected with the upper die plate 1 through a through hole in the clamping plate 3, and the through hole plays a role in fixing the punch 2. The lower die part comprises a lower template 6, and punched holes matched with the punch 2 are formed in the position, corresponding to the punch 2, of the lower template 6. The upper part of the punch is placed with the product 5 to be punched. And the positioning pin 7, namely a guide post, is arranged in the clamping plate 3, and the lower end of the positioning pin extends into the lower template 6 and is used for guiding the die opening and die closing of the die.

Punch 2 on still the cover be equipped with the dominant force and glue 4, the upper end and the splint 3 of dominant force glue 4 be connected. When the acrylic rubber 4 is in a non-stretching or compressing state, the height of the acrylic rubber 4 is not less than that of the outer limiting column. When the punch 2 moves downwards and penetrates through the product 5 to be punched, the high-strength glue 4 can be pressed on the product 5 at the periphery of the punched hole, and the product 5 at the two ends of the punched hole is prevented from tilting due to the punching force of the punch 2.

The upper die part is fixed to the upper table surface of the punch press and the lower die part is fixed to the lower table surface of the punch press in a closed die state during production. After the die height is adjusted, the punch is started to move, when the punch moves upwards to the highest point position, the positioning pin 7 for positioning the upper die and the lower die is taken away, the product 5 is placed on the lower die plate 6, and the part to be punched is opposite to the punched hole. When the punch moves downwards, the high-strength rubber 4 presses the product 5, the punch 2 punches through the product 5, and holes which are not punched on the product 5 are machined. When the punch returns to move upwards, the punch 2 is driven to move upwards, and at the moment, the high-strength rubber 4 has elasticity, so that the punch 2 is conveniently separated from the product 5, and the purpose of reworking and punching the product 5 is achieved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the concept of the present invention, and these improvements and decorations should also be considered as the protection scope of the present invention.
