Abstract
The invention discloses a punching die for cylindrical walls. The punching die comprises a lower die base and a die shank. A female die frame and a female die block which are detachably connected are fixedly connected to the lower die base. A male die is detachably connected to the die shank. The working faces of the female die block and the male die are arc-shaped and have the same radian. The normal of the working face of the male die and the center line of the die shank are non-collinear. The punching die is mainly used for punching from the interior of cylindrical parts; through matching of the female die block and the male die which are detachably connected, different female die blocks and male dies can be produced and replaced according to the cylindrical parts in different specifications; the normal of the working face of the male die and the center line of the die shank are non-collinear, so that the die shank can be kept away from the distance between a cylinder punching position and a cylinder end during punching.
Description
Technical field
The invention belongs to diel, be specifically related to cylindrical wall perforating die.
Background technology
Diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacture.In diel field, for part miscellaneous, all can design corresponding upper and lower mould, to can realize batch production.Just the process requirements of perforate on cylindrical wall part, very high to the processing request precision of punching, because being is adding man-hour to thin cylinder part, therefore needs a kind of cylindrical wall perforating die that adapts to the cylinder part barrel punching processing of different size.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cylindrical wall perforating die that adapts to the cylinder part barrel punching of different size.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: cylindrical wall perforating die, comprise die shoe and die shank, the die piece that is fixedly connected with die frame on die shoe and removably connects with it, is removably connected with punch on die shank; The working face of die piece and punch is circular arc, and both circular arc radians are identical; The working face normal of punch and the center line of die shank be conllinear not.
Technique scheme is mainly used in carrying out the processing needs of punching in cylinder part cylinder, under the cooperation of the die piece removably connecting and punch, can manufacture and change different die piece and punch according to the cylinder part of different size (if barrel radian, punching position are apart from the distance at cylinder two ends etc.), the working face normal of punch and the center line of die shank not conllinear are in order to allow die shank avoid the distance of cylinder punching position and cylinder termination in punching course.The technical program has realized the process requirements of the cylinder part of different size being carried out to punching, has also met the process requirements from starting punching press in cylinder simultaneously.
As the further optimization of technique scheme, for fear of die shank, in punching course, touch the barrel relative with the position of wanting punching with punch, on die shoe, be also provided with the limited block that limits punch displacement amount.
As the further optimization of technique scheme, in order to fix better the position of cylinder part, make not occur in process that part fixes unsettled problem, near limited block, be provided with baffle plate.
Accompanying drawing explanation
Fig. 1 is the structural representation of cylindrical wall perforating die of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further detailed explanation:
As shown in Figure 1, cylindrical wall perforating die, comprises die shoe 7 and die shank 1, and the die piece 6 that is fixedly connected with die frame 5 on die shoe 7 and removably connects with it, is removably connected with punch 4 on die shank 1; Die piece 6 is circular arc with the working face of punch 4, and both circular arc radians are identical; The working face normal of punch 4 and the center line of die shank 1 be conllinear not, is also provided with the limited block 3 that limits punch displacement amount on die shoe 7, is also provided with the baffle plate 2 of stablizing cylinder part on limited block 3.
Above-described is only the preferred embodiment of the present invention, should be understood that for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
Claims (3)
