Description

Stamping die

Technical Field

The utility model belongs to the technical field of mechanical stamping, concretely relates to stamping die.

Background

In the production technology of automobile parts, the punching operation of various parts is often involved, hole sites of specific parts are formed or products are punched, in the punching process, the parts are often difficult to obtain final shapes through one-time punching, the parts need to be transported in different punching dies, and in the transporting process in different punching dies, the relative positions between the parts and the positioning grooves need to be ensured to have higher accuracy, when the deviation of the placement positions occurs or the punching acting force received is higher, the outer edge parts of the formed parts and the inner edge parts of the positioning grooves generate larger shearing acting force, and further the deformation of the parts is caused, therefore, the precision requirement of the placement positions of the parts by the existing punching dies is higher, and meanwhile, the risk of edge deformation is higher.

SUMMERY OF THE UTILITY MODEL

To the technical problem that exists, the utility model provides a stamping die to there is spare part to place the required precision height in solving current stamping die, has the problem that the edge deformation risk is high simultaneously, and this stamping die can cushion spare part edge part's atress in stamping process, avoids the emergence that spare part warp.

The utility model discloses a stamping die, include bed die, elastic component, go up mould, backup pad and elevating system, but go up the mould set up in but the oscilaltion ground in the top of bed die, the bottom of backup pad with the top of going up the mould is passed through elastic component interconnect, elevating system connects the backup pad, the product constant head tank has been seted up to the top surface of bed die, the inside of product constant head tank is encircleed and is provided with flexible circle, flexible circle with the packing has buffer material before the inner edge of product constant head tank, the bottom of product constant head tank has been seted up and has been link up the blanking hole of bed die, it corresponds to go up the mould bottom the position in blanking hole is provided with the cutter that punches a hole.

Further, the elastic member is a spring.

Furthermore, the stamping die further comprises a base, the lower die is located above the base, and a discharging channel is formed in the position, corresponding to the blanking hole, of the base.

Furthermore, a plurality of guiding holes are formed in the periphery of the upper die, a plurality of guiding columns are arranged on the base corresponding to the plurality of guiding holes, and the plurality of guiding columns penetrate through the plurality of guiding holes in a one-to-one correspondence mode.

This stamping die can with treat the punching press when carrying out spare part punching press operation place in inside the flexible circle of product constant head tank, through go up the mould and drive the punching press cutter punches a hole downwards, the waste material after the punching press by blanking hole discharge, this stamping die through set up in the flexible circle and the buffer material of product constant head tank inner edge can play direction and positioning action to the spare part before the punching press, reduce the requirement to the part precision of placing, play the cushioning effect to the shearing force that the spare part edge received when the punching press simultaneously, and then avoid the deformation at spare part edge, satisfy the edge and carry out the demand of punching press many times for the spare part of thin wall construction, improve product shaping yield.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic structural view of a stamping die.

Detailed Description

The utility model discloses a stamping die, this stamping die can cushion spare part edge part's atress at the stamping process, avoids the emergence that spare part warp.

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, only some embodiments, not all embodiments, of the present invention are described. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, the utility model discloses a stamping die, including bed die 3, elastic component 7, go up mould 1, backup pad 6 and elevating system 5, it can set up with oscilaltion in bed die 3's top to go up mould 1, the bottom of backup pad 6 with the top of going up mould 1 passes through elastic component 7 interconnect, elevating system 5 connects backup pad 6, product location groove 14 has been seted up to bed die 3's top surface, the inside of product location groove 14 is encircleed and is provided with flexible circle 11, flexible circle 11 with it has buffer material 10 to fill before the inner edge of product location groove 14, the bottom of product location groove 14 is seted up and is link up the blanking hole 13 of bed die 3, it is provided with punching tool 2 to go up mould 1 bottom corresponding the position of blanking hole 13.

The elastic member 7 is a spring.

The stamping die further comprises a base 4, the lower die 3 is located above the base 4, and a discharging channel 12 is formed in the position, corresponding to the blanking hole 13, on the base 4.
