Abstract

The utility model provides a closed double-action punching die, which comprises an upper die and a lower die, wherein a forge piece is arranged between the upper die and the lower die; a punch is arranged above the upper die and below a punch fixing plate; an upper die baseplate is mounted on the punch fixing plate; and a lower die baseplate is mounted below the lower die. The closed double-action punching die is characterized in that a punch guide pillar is arranged below the punch fixing plate, a compression spring is sleeved on the punch guide pillar, the lower end of the compression spring is fixed on the top surface of the upper die, the upper die is sleeved on an upper die guide pillar, a lock nut is mounted at the top of the upper die guide pillar, and a return spring is sleeved on the upper die guide pillar. Due to the adoption of the closed double-action punching die, the punch processing of the forge piece is carried out in the closed space so that deformation of the forge piece is completely avoided.

Description

Enclosed double action punching die
Technical field
The utility model relates to the punching processing of forging when producing, and specifically, relates to a kind of enclosed double action punching die.
Background technology
At present, common forging punching die is the open type punching.Because in punch process, patrix does not compress forging, forging makes its buckling deformation in punching moment owing to shear the tension that produces, and has a strong impact on product quality.
The utility model content
The purpose of the utility model is to overcome above-mentioned technical problem, provides a kind of forging of avoiding to produce the mould that forges the punching distortion.
The concrete technical scheme of the utility model is following:
A kind of enclosed double action punching die comprises upper die and lower die, places forging between patrix and the counterdie, and the patrix top is provided with drift, and drift is installed in drift fixed head below, installs baffle plate on the drift fixed head, and baffle plate is down installed in the counterdie below; It is characterized in that: drift fixed head below is provided with the drift guide pillar, sheathed compression spring on the drift guide pillar, and compression spring lower end is fixed on the patrix end face, and Upper Die-sleeve is on the patrix guide pillar, and locking nut, sheathed back-moving spring on the patrix guide pillar are installed in patrix guide pillar top.
As a kind of improvement, said patrix is the patrix that floats, and the drift targeting port is offered at the patrix middle part.
As further improvement, said patrix guide pillar is provided with guide pin bushing, and back-moving spring is between guide pin bushing and following baffle plate.
Beneficial effect:
The enclosed double action punching die of the utility model; Forging is before accomplishing the punching action; The patrix base moves down; Thereby the patrix that floats is owing to receive the elastic force of the compression spring that is installed on the patrix base and move downward, up to Work-sheet pressing and with near closed hollow ring of the sturdy formation of counterdie till, this moment drift just the postorder follow-up accomplish punching processing.Carry out in enclosure space with regard to the punching processing that has formed forging like this, avoided the generation of forging distortion fully.
Description of drawings
Fig. 1 is the utility model preparation status architecture sketch map;
Structural representation when Fig. 2 compresses forging for the utility model patrix is moved downward to counterdie;
Structural representation when Fig. 3 gets into the drift targeting port of patrix for the utility model drift;
Structural representation when Fig. 4 accomplishes the punching action downwards for the utility model drift;
Fig. 5 is the side-looking structural representation of the enclosed double action punching die of the utility model;
Among the figure: the last baffle plate of 1-, 2-drift fixed head, 3-drift guide pillar, the 4-drift, 5-compresses spring, 6-locking nut, 7-patrix, 8-guide pin bushing, 9-back-moving spring, 10-patrix guide pillar, 11-counterdie, baffle plate under the 12-, 13-forging, 14-drift targeting port.
The specific embodiment
In conjunction with accompanying drawing, do further describing down in the face of the utility model.
A kind of enclosed double action punching die comprises patrix 7, counterdie 11, places forging 13 between patrix 7 and the counterdie 11; Patrix 7 tops are provided with drift 4; Drift 4 is installed in drift fixed head 2 belows, installs baffle plate 1 on the drift fixed head 2, and baffle plate 12 is down installed in counterdie 11 belows; It is characterized in that: drift fixed head 2 belows are provided with drift guide pillar 3; Sheathed compression spring 5 on the drift guide pillar 3, compression spring 5 lower ends are fixed on patrix 7 end faces, and patrix 7 is enclosed within on the patrix guide pillar 10; Locking nut 6, sheathed back-moving spring 9 on the patrix guide pillar 10 are installed in patrix guide pillar 10 tops.
Said patrix 7 is the patrix that floats, and drift targeting port 14 is offered at patrix 7 middle parts; Said patrix guide pillar 10 is provided with guide pin bushing 8, and back-moving spring 9 is between guide pin bushing 8 and following baffle plate 12.
At last, it is also to be noted that what more than enumerate only is the practical implementation example of the utility model, obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought the protection domain of the utility model.
