Abstract
A piercing punch head comprises a guide part and a work part, wherein the work part comprises a hole squeezing zone and a piercing zone; an oil groove is formed between the hole squeezing zone and the piercing zone; the hole squeezing zone is connected with the guide part; the outer diameter of the piercing zone is the minimum limit value of the pierced hole diameter; and the outer diameter of the hole squeezing zone is the maximal limit value of the pierced hole diameter. The utility model pierces and processes holes, thereby not only improving the working efficiency, but also prolonging the service life of the piercing punch head, and reducing the production cost. In the situation that the size of the hole squeezing zone does not exceed the piercing tolerance range, the piercing punch head can be used all the time. The practice proves that the service life of the piercing punch head of the utility model made of the same materials as the common punch head can reach up to more than sixty thousand times; and the structure combining the piercing and squeezing can not only ensure the punching accuracy, but also improve the euphotic zone level of the holes.
Description
Technical field
The utility model relates to a kind of punch of cold punching die, particularly a kind of pierce punch that is used for the stamping-out hole.
Background technology
The pierce punch that generally uses in the industry, be about 20,000 normal service life, but in the actual use because rubbing always with steel part, cause wearing and tearing, caused the size in the hole that processes changing always, precision less than assurance, the situation of wear out failure also occurs repeatedly.If when needing requirement on machining accuracy than higher hole, just need the frequent drift of changing, wasted the time and artificial, reduced production efficiency; Usually the means that promote drift service life are to be coated with one deck abrasion-resistant coating at the drift working portion, but the drift price of producing like this is very expensive, is tens times even hundreds of times of general drift, and under little in batches situation, it is very high that its cost just seems.
Summary of the invention
Problem to be solved in the utility model is: existing common pierce punch wearing and tearing are big, can not satisfy user demand, and wear-resisting drift cost height, need provide a kind of cheap, long service life, dependable performance pierce punch.
The technical solution of the utility model is: pierce punch, comprise targeting part and working portion, working portion comprises crowded porose area and punch area, between crowded porose area, punch area, be provided with oil groove, squeeze porose area and connect targeting part, the external diameter of punch area is the aperture minimum limit value of institute's punching, and the external diameter that squeezes porose area is the aperture maximum limit of institute's punching.
The degree of depth of the utility model oil groove is less than 1mm, prevents from that the working portion intensity of pierce punch is low excessively to cause fracture; Targeting part, crowded porose area, punch area, oil groove are integrated.
The external diameter of the utility model punch area is the aperture minimum limit value of institute's punching, and the external diameter that squeezes porose area is the aperture maximum limit of institute's punching, to squeezing behind the local subpunch of wanting punching, finishes punch work jointly by punch area and crowded porose area during use.
The utility model carries out the stamping-out machining hole, can enhance productivity, can prolong again pierce punch service life, reduce production costs, do not exceed under the margin of tolerance situation of institute's punching in crowded porose area size, the utility model can use always, facts have proved that the utility model pierce punch that adopts the same material of common drift to make can reach more than 60,000 times its service life; The structure of impact extrusion combination not only can guarantee the precision of punching, can also improve the euphotic belt level in hole.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises targeting part 1 and working portion, working portion comprises crowded porose area 2 and punch area 3, between crowded porose area 2, punch area 3, be provided with oil groove 4, squeeze porose area 2 and connect targeting part 1, targeting part 1, crowded porose area 2, punch area 3 and oil groove 4 are integrated, and the external diameter of punch area 3 is the aperture minimum limit value of institute's punching, the external diameter that squeezes porose area 2 is the aperture maximum limit of institute's punching, and the depth H of oil groove 4 is less than 1mm.
When the utility model uses, according to the aperture of want punching and the pierce punch of required precision selection suitable dimension, the punch area 3 of pierce punch can be gone out the aperture minimum of a value in required hole earlier, squeezing porose area 2 makes the aperture expand the aperture maximum of institute's punching to again, punch area 3 and crowded porose area 2 are finished punch work jointly, the oil groove 4 that is provided with can help to reduce the wearing and tearing of punch workpiece to the punching punch head surface, wearing and tearing when punch area 3 and crowded porose area 2 have been shared punching, even be subjected to some wearing and tearing, the punch area of two-part and crowded porose area can guarantee that also the aperture of institute's punching is in the required precision scope.
The utility model is the workpiece of stamping-out thickness≤4mm directly, if desired during Jia Gong thickness of workpiece＞4mm, directly stamping-out may cause workpiece deformation, and increase one-off hole-piercing operation according to the size of workpiece and the big I in hole this moment, processes with pierce punch after leaving and taking suitable surplus again.
Claims (3)
