Abstract
The invention discloses a die punch. The die punch is characterized by comprising a punch body, a female die, a cone and sliding balls, the punch body is matched with the female die, the cone is mounted at the center of the bottom end of the punch, the sliding balls are mounted in the female die, an angle range of the cone is from 60 degrees to 120 degrees, a forming hole is formed in the female die, and the sliding balls are arranged in an upper port and a lower port of the forming hole and are in a ring array by centering in the axis of the forming hole. By the means, friction of the die punch is reduced through the sliding balls, so that wear of the die punch is reduced, and service life of the die punch is prolonged.
Description
Technical field
The present invention relates to mould applications, relate in particular to a kind of mold and punching head.
Background technology
Drift is mounted in the metal parts in diel, is applied to contact with the direct of material, makes material generation deformation, cuts material.
Mold and punching head generally adopts high-speed steel and wolfram steel etc. as material, high-speed steel drift and wolfram steel drift etc. are arranged, and high-speed steel is the most frequently used material, commonly used have CR12, CR12MOV, asp23, skd11, skd51, skd61 etc., and the wolfram steel material generally is used on the punching and shearing die of having relatively high expectations.
In routine duties, drift can produce wearing and tearing, and main wearing and tearing comprise: mechanical wear and thermal wear, reduced quality and the precision of mould, and need often to change drift, greatly increased the production cost of mould.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of mold and punching head, and this mold and punching head reduces by the friction that makes drift of advance ball, thereby has reduced the wearing and tearing of mold and punching head, has increased the service life of mold and punching head.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of mold and punching head, it is characterized in that, and comprising: drift, die, cone and advance ball, described drift and described die cooperatively interact;
Described cone is arranged on described drift bottom center;
Described advance ball is arranged in described die.
In a preferred embodiment of the present invention, the angular range of described cone is 60 ° to 120 °.
In a preferred embodiment of the present invention, in described die, be provided with forming hole.
In a preferred embodiment of the present invention, upper port and the lower port of described forming hole are provided with advance ball.
In a preferred embodiment of the present invention, described advance ball be take described forming hole axle center as center of circle circular array.
The invention has the beneficial effects as follows: mold and punching head of the present invention reduces by the friction that makes drift of advance ball, thereby has reduced the wearing and tearing of mold and punching head, has increased the service life of mold and punching head.
The accompanying drawing explanation
Fig. 1 is the structural representation of mold and punching head of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, drift; 2, die; 3, cone; 4, advance ball; 5, forming hole.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises: a kind of mold and punching head, it is characterized in that, and comprising: drift 1, die 2, cone 3 and advance ball 4, described drift 1 cooperatively interacts with described die 2, makes mould molding more accurate, and quality is higher.
Described cone 3 is arranged on described drift 1 bottom center, and the angular range of described cone 3 is 60 ° to 120 °, the different described cone according to the different choice of machining kinds.
Be provided with forming hole 5 in described die 2, play into the effect of mould.
The upper port of described forming hole 5 and lower port are provided with advance ball 4, and described advance ball 4 contacts with described drift 1, have reduced the friction of described drift 1 and described die 2, adopt upper and lower double-layer structure to make location more accurate.
It is center of circle circular array that described advance ball 4 be take described forming hole 5 axle center, the precision while being conducive to increase described drift 1 work.
Below the operation principle of mold and punching head of the present invention described in detail.
During use, plate is placed on die 2, the cone of drift 13 center lines are alignd with the axle center of forming hole 5, during work, drift 1, by contacting with forming hole 5 upper and lower end advance balls 4, makes cone 3 that plate is extruded into to mould from forming hole 5.
Compared with prior art, mold and punching head of the present invention reduces by the friction that makes drift of advance ball, thereby has reduced the wearing and tearing of mold and punching head, has increased the service life of mold and punching head.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
Claims (5)
