Abstract

The utility model discloses a self pressure discharging detachable self-locking punch which comprises a clamp and a punch. A neck provided with the punch is formed in the clamp. A threaded hole is formed in the lateral side of the clamp and inclined towards the inner end of the punch in a drilling mode. A screw is screwed in the threaded hole. A plane corresponding to the end face of the screw is arranged on one side, corresponding to the inner end portion of the threaded hole, of the punch. Detachable replacement of the punch is achieved, and a self-locking function is ensured. Meanwhile, the punch has a self pressure discharging function, degree of damage under a high pressure stamping environment is reduced, and service life is prolonged.

Description

From release dismountable self-locking drift
Technical field
The utility model relates to a kind of drift, relates in particular to a kind of from release dismountable self-locking drift.
Background technology
Although the plunger chip die that uses has at present had rapid progress and raising, in the employed drift of existing press machine, drift will be mostly in use in case after damaging, if can not in time change drift, will cause unitary mould all to be scrapped; Because in punching course, drift has born huge pressure, and existing drift has aggravated again the process that drift damages all without from pressure relief, and under long-term impacting with high pressure, in a single day drift damages, and just will slow down manufacturing schedule.
Summary of the invention
The purpose of this utility model provides a kind of from release dismountable self-locking drift.
The purpose of this utility model is achieved through the following technical solutions:
Of the present utility model from release dismountable self-locking drift, comprise anchor clamps and drift, described anchor clamps 1 are provided with the draw-in groove that drift is installed, the side of described anchor clamps, interior extreme direction inclination auger shell pit to drift, DRIVE SCREWS in the screwed hole mills out the plane that the end face with screw adapts at the position of the corresponding screwed hole of side the inner of drift.
Can be found out by the technical scheme that above-mentioned the utility model provides, the utility model embodiment provide from release dismountable self-locking drift, because anchor clamps are provided with the draw-in groove that drift is installed, the side of described anchor clamps, interior extreme direction inclination auger shell pit to drift, DRIVE SCREWS in the screwed hole mills out the plane that the end face with screw adapts at the position of the corresponding screwed hole of side the inner of drift.Realize the detachable replacing of drift, and guarantee to have auto-lock function.It is possessed from decompression function, reduce the damaged condition under the high pressure punching press environment, life-extending.
Description of drawings
The Facad structure schematic diagram from release dismountable self-locking drift that Fig. 1 provides for the utility model embodiment;
Fig. 2 for the utility model embodiment provide from the side of release dismountable self-locking drift sectional structure schematic diagram.
The specific embodiment
The below will be described in further detail the utility model embodiment.
Of the present utility model from release dismountable self-locking drift, its better specific embodiment is:
Comprise anchor clamps and drift, described anchor clamps are provided with the draw-in groove that drift is installed, and the side of described anchor clamps is to the interior extreme direction inclination auger shell pit of drift, DRIVE SCREWS in the screwed hole mills out the plane that the end face with screw adapts at the position of the corresponding screwed hole of side the inner of drift.
Described anchor clamps are rectangular jig.
Described screw is interior six side's screws or crosshead screw or manifold screw.
Of the present utility model from release dismountable self-locking drift, be on the basis of existing plunger chip die, guaranteeing on original punching precision.According to drift processing, realize the detachable replacing of drift, and guarantee to have auto-lock function.It is possessed from decompression function, reduce the damaged condition under the high pressure punching press environment, life-extending.Fixedly the gap of drift and mould prevents in use, and deviation occurs in the drift position, causes work piece to damage.
Specific embodiment:
As shown in Figure 1 and Figure 2, the anchor clamps 1 and the drift 3 that comprise a rectangle, stamp out the area of drift 3 sizes of required installation and the draw-in groove of the degree of depth at anchor clamps 1, side at anchor clamps, interior extreme direction inclination auger shell pit to drift 3, six side's screws 2 in screwed hole screws in mill out the plane that the end face with interior six side's screws 2 adapts at the position of drift 3 one sides correspondence screwed hole the inner.After drift 3 and anchor clamps 1 assemble, screw interior six side's screws 2, drift 3 is fixing with anchor clamps 1.
The beneficial effect that technical solutions of the utility model are brought:
Because this utility model does not have excessive body to change, thus cost do not increased, good in economic efficiency.The utility model is simple in structure, and is easily manufactured;
This utility model has solved the non-detachable problem of original plunger holder drift, in the situation that drift damages, is convenient for changing the drift of damage, enhances productivity, and reduces production costs;
In anchor clamps and drift assembling, make drift in use, high pressure is unloaded voluntarily, the protection drift reduces the infringement that punching press causes.Further improve drift service life, reduce financial cost;
The rake angle boring of anchor clamps side, six square nuts in using when being that drift is fixedly, reach the firm maximum effect of clamping;
The utility model is that drift miller angle position cooperates with the angle of anchor clamps screwed hole and interior six square nuts, makes its firm chucking.Has its auto-lock function.Simultaneously can unload in use most of stamping pressure to drift in the anchor clamps internal structure, reduce the drift wearing and tearing, prolong drift service life.Interior six square nuts that use special substance to make.Sturdy and durable.But iterative cycles uses, and makes things convenient for the drift dismounting.
The utility model patent is compared with existing several patents of invention, following some advantage is arranged with different.
The utility model is in existing impact machine bed diel, transforms, and only needs can use through special processing.Do not improve design cost.Can maximumly transform and use diel.
The utility model use special substance make in six square nuts, can be repeatedly removing damaged drift, and will all not changing by whole plunger chip die, Cost reduction is enhanced productivity.
This punching clamp with the drift assembling process in, fully take into account the pressure transmission effects.Through special processing, but drift possess from pressure relief, reduced the drift surge, improve drift service life.
The utility model drift not only possesses changes the detachable function of drift, and interior six square nuts that are used in conjunction with through special processing and special angle.Make it possess auto-lock function, chucking firmly.
The utility model, simple in structure, easily manufactured, be connected firmly.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
