Abstract
The invention provides a closed type double-acting punching mold. The closed type double-acting punching mold comprises an upper mold and a lower mold, wherein a forging piece is placed between the upper mold and the lower mold; a punching head is arranged above the upper mold and below a punching head fixing plate; an upper mold bottom plate is arranged on the punching head fixing plate; and a lower mold bottom plate is arranged below the lower mold. The closed type double-acting punching mold is characterized in that a punching head guide column is arranged below the punching head fixing plate; a compression spring is sheathed on the punching head guide column; the lower end of the compression spring is fixed on the top surface of the upper mold; the upper mold is sheathed on an upper mold guide column; the top of the upper mold guide column is provided with a locking nut; and a return spring is sheathed on the upper mold guide column. According to the closed type double-acting punching mold provided by the invention, the punching processing of the forging piece is carried out in a closed space, so that the deformation of the forging piece is completely avoided.
Description
Technical field
The present invention relates to forge the punching processing when producing, specifically, relate 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.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical problem, provide a kind of forging of avoiding to produce the mould that forges the punching distortion.
Concrete technical scheme of the present invention is as follows:
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, described patrix is the patrix that floats, and the drift targeting port is offered at the patrix middle part.
As further improvement, described patrix guide pillar is provided with guide pin bushing, and back-moving spring is between guide pin bushing and following baffle plate.
Beneficial effect:
Enclosed double action punching die of the present invention, forging is before finishing the punching action, the patrix base moves down, the patrix that floats is owing to thereby the elastic force that is subjected to being installed in the compression spring on the patrix base moves 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 finish 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 a preparation status architecture schematic diagram of the present invention;
Structural representation when Fig. 2 compresses forging for patrix of the present invention is moved downward to counterdie;

Fig. 5 is the side-looking structural representation of enclosed double action punching die of the present invention;
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 the accompanying drawings, below the present invention is described further.
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.
Described patrix 7 is the patrix that floats, and drift targeting port 14 is offered at patrix 7 middle parts; Described 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 specific embodiments of the invention, obviously, the invention is not restricted to above examples of implementation, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
