Abstract

The invention discloses a damping die punch which comprises a punch rod, a female die, a conical body, a damping spring and a buffer inner rod. The punch rod is mutually matched with the female die. An inner rod hole is formed in the punch rod. The buffer inner rod is connected with the inner rod hole. The conical body is connected wit the buffer inner rod. The damping spring is connected with the inner rod hole. Slide edges are formed on the lateral sides of the buffer inner rod. Slide grooves are formed in the inner rod hole. A limit block is disposed at the bottom end of each slide groove. By the arrangement, impact of the punch rod is reduced through the spring, abrasion of the die punch rod is lowered, and the service life of the die punch rod is prolonged.

Description

Bradyseism mold and punching head
Technical field
The present invention relates to mould applications, relate in particular to a kind of bradyseism 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, there are high-speed steel drift and wolfram steel drift etc., and high-speed steel is the most frequently used material, conventional have CR12, CR12MOV, asp23, skd11, skd51, skd61 etc., and wolfram steel material is generally 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 bradyseism mold and punching head, and this bradyseism mold and punching head makes plunger rod reduce impulsive force by spring, thereby has reduced the wearing and tearing of mold and punching head bar, has increased the service life of mold and punching head bar.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of bradyseism mold and punching head, comprising: bar in plunger rod, die, cone, bradyseism spring and buffering, and described plunger rod and described die cooperatively interact;
Described plunger rod is provided with interior bar hole;
In described buffering, bar is connected with described interior bar hole;
Described cone is connected with bar in described buffering;
Described bradyseism spring is connected with described interior bar hole;
In described buffering, bar side is provided with sliding rib;
Described interior bar is provided with chute in hole;
Described chute bottom is provided with limited block.
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, described sliding rib matches with described chute.
In a preferred embodiment of the present invention, match with bar in described buffering in described interior bar hole.
The invention has the beneficial effects as follows: bradyseism mold and punching head of the present invention makes plunger rod reduce impulsive force by spring, thereby has reduced the wearing and tearing of mold and punching head bar, has increased the service life of mold and punching head bar.
Accompanying drawing explanation
Fig. 1 is the structural representation of bradyseism mold and punching head of the present invention.
Structural representation when Fig. 2 is the work of bradyseism mold and punching head of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, plunger rod; 2, die; 3, cone; 4, bradyseism spring; 5, bar in buffering; 6, slide rib; 7, chute; 8, locating piece; 9, forming hole; 10, interior bar 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 and Fig. 2, the embodiment of the present invention comprises: a kind of bradyseism mold and punching head, comprising: bar 5 in plunger rod 1, die 2, cone 3, bradyseism spring 4 and buffering, and described plunger rod 1 cooperatively interacts with described die 2, make mould molding more accurate, quality is higher.
Described plunger rod 1 is provided with interior bar hole 10, and in described buffering, bar 5 is connected with described interior bar hole 10, and matching with bar 5 in described buffering in described interior bar hole 10, is conducive to the bumper and absorbing shock of device.
Described cone 3 is connected with described plunger rod 1, and the angular range of described cone 3 is 60 ° to 120 °, according to the different described cone 3 of the different choice of machining kinds.
Described bradyseism spring 4 is connected with described interior bar hole 10, and described bradyseism spring 4 has played the effect that reduces at work described plunger rod 1 impulse force.
In described buffering, bar 5 sides are provided with sliding rib 6, in described interior bar hole 10, are provided with chute 7, and described sliding rib 6 matches with described chute 7, make bar 5 in described buffering in the 10 interior slips of described interior bar hole, thereby compress described bradyseism spring 4, to make to reduce impulsive force.
Described chute 7 bottoms are provided with limited block 8, thereby when described limited block 8 can be worked as device return, avoid bar 5 in described buffering to depart from and cause to use next time with described interior bar hole 10.
In described die 2, be provided with forming hole 9, play into the effect of mould.
Below the operation principle of bradyseism mold and punching head of the present invention is described in detail.
During use, plate is placed on die 2, cone 3 center lines of bar 5 in buffering are alignd with the axle center of forming hole 9, during work, plunger rod 1 moves down, cone 3 contact materials, the now chute 7 interior slip of the sliding rib 6 of bar 5 sides in interior bar hole 10 in buffering, 4 compressions of bradyseism spring, make cone 3 that plate is extruded into mould from forming hole 9, and during return, bradyseism spring 4 ejects, in buffering, the sliding rib 6 of bar 5 sides contacts with limited block 8, avoids cushioning interior bar 5 separated with interior bar hole 10.
Compared with prior art, bradyseism mold and punching head of the present invention makes plunger rod reduce impulsive force by spring, thereby has reduced the wearing and tearing of mold and punching head bar, has increased the service life of mold and punching head bar.
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 description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
