Description

Stamping die buffer

Technical Field

The utility model relates to a technical field is made to the mould, specifically is a stamping die buffer.

Background

The application of the existing mold relates to each product (such as automobiles, spaceflight, daily necessities, electrical appliance communication, medical product equipment and the like), and the mold can be used for producing a large number of products, and is an integral part of the mold. At present, the precision requirement of the mold can be determined according to different levels and product requirements, and the rong mark and the translational mold can be just matched with different requirements of various customers to provide proper supply.

The die is a semi-finished product of the die and is composed of various steel plates matched with parts, so to speak, the framework of the whole die. Because the processing related to the die and the die is very different, a die manufacturer can choose to order the die from the die manufacturer, and the production advantages of the two parties are utilized to improve the overall production quality and efficiency.

In the existing stamping die, an upper die and a lower die are in rigid contact when stamping work is carried out, and the acting force between the upper die and the lower die is large and easy to damage due to the fact that the pressure output by a press machine is large.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.

The utility model provides a stamping die buffer, includes mould, lower mould, and the bottom fixed mounting who goes up the mould has the terrace die, has the die that corresponds with the terrace die on the lower mould, and the bottom elastic connection of going up the mould has the clamp plate, has the terrace die guide hole on the clamp plate, and the terrace die is arranged in the terrace die guide hole and with it sliding fit, and the bottom of terrace die is no longer than the lower extreme of terrace die guide hole under the die sinking state, and the bottom fixedly connected with supporting baseplate of lower mould corresponds the shaping with the die on the supporting baseplate and has.

Furthermore, a round hole is formed in the pressing plate, a pressing plate guide pillar which penetrates through the round hole and is fixedly connected with the bottom of the upper die is arranged in the round hole, and a spring connected between the bottom of the upper die and the top of the pressing plate is sleeved on the pressing plate guide pillar.

Furthermore, the bottom end of the round hole is expanded outwards to form a limiting groove, and a limiting flange corresponding to the limiting groove is formed at the bottom end of the pressure plate guide pillar.

Furthermore, a buffer gasket is connected between the bottom of the lower die and the supporting bottom plate.

Furthermore, the diameter of the blanking hole is gradually enlarged from top to bottom.

Furthermore, the upper die, the pressing plate, the lower die and the supporting bottom plate are formed with guide holes on the same vertical line, and guide rods which penetrate through the upper die, the pressing plate, the lower die and the supporting bottom plate and are in sliding fit with the upper die, the pressing plate, the lower die and the supporting bottom plate are arranged in the guide holes.

Compared with the prior art, the utility model discloses the beneficial effect who gains does: the utility model discloses novel structure adopts the clamp plate structure, carries out the pre-compaction to the material in stamping process and fixes, prevents the skew, avoids direct punching press to lead to work piece size deviation because the material rises, utilizes the elastic buffer structure simultaneously, goes up the impact force between mould, the lower mould when reducing the punching press, and protection die avoids impaired.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
