Description

A kind of punching tooling

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of punching tooling, particularly a kind of diaphragm punching tooling.

Background technology

Diaphragm is the important component part of valve, and the general valve that is used for having self-regulating function is used for responding to the pressure reduction between the indoor fluid of valve body inner septum sheet upper and lower cavity.Diaphragm is generally in the form of annular discs, and the center of diaphragm has through hole, and this through hole is used for stationary links, and diaphragm is connected with spool.

In the valve process of manufacture, when producing diaphragm, need to carry out perforation processing to diaphragm, at present, due to the process mould problem, the diaphragm of producing does not comprise mesopore, and this just need to carry out perforation processing to it after diaphragm production is completed.Because diaphragm is generally to be made by elastomeric material, rubber has certain elasticity, existing puncher is when hitting the hole to diaphragm, some deviations often appear in the position in the hole of being up to, and the size in aperture also is difficult to guarantee to meet the requirements, product percent of pass is low, and production efficiency is low.

Summary of the invention

The purpose of this utility model is for the above-mentioned problems in the prior art, and a kind of high punching tooling of precision of producing is provided.

The purpose of this utility model can realize by following technical proposal: a kind of punching tooling, comprise base, it is characterized in that, be fixed with framework on described base, be connected with motion bar on described framework, also be provided with handwheel on described framework, has transmission mechanism between described handwheel and motion bar, the bottom of described motion bar is connected with drill bit, be fixed with upper cover on described drill bit, described base is provided with subiculum in the form of annular discs, and the center of described subiculum has groove, and groove and above-mentioned drill bit are over against setting.

The shape of the subiculum of this punching tooling and the shape of processed diaphragm are complementary, diaphragm evagination dome and subiculum outer rim match, and when diaphragm is carried out perforation processing, diaphragm are enclosed within on subiculum, the groove that makes the center of diaphragm and subiculum center over against, rotate handwheel, motion bar is moved down, drill bit rushes at groove, it is the center of diaphragm, upper cover is pressed in diaphragm on subiculum, and blocking diaphragm can be not flexible inwards because of extruding, and punching is realized at the center of diaphragm.Cooperation by subiculum and upper cover can not be moved diaphragm when punching, the center of diaphragm is overlapping with the groove of subiculum center all the time, and the position during punching is accurate, and pore size is consistent, and the production precision is high.

In above-mentioned a kind of punching tooling, be fixed with installing plate on described framework, has the track that slides for motion bar on described installing plate, described transmission mechanism comprises that a side of above-mentioned motion bar has tooth bar, the end of described handwheel is fixed with gear one, and described gear one is connected with above-mentioned tooth bar by gear two.Handwheel rotates counterclockwise, handwheel driven gear one rotates counterclockwise, gear one driven gear two clockwise rotates, clockwise rotating of gear two moves down motion bar, thereby drill bit is moved down, until drill bit is pressed on subiculum, realize the punching to diaphragm, drive mechanism is simple, and transmission accuracy is high.

In above-mentioned a kind of punching tooling, be provided with back-moving spring between described motion bar and framework, above-mentioned back-moving spring one end is connected with the top of motion bar, and the other end is fixed on framework.After frock is completed once punching, unclamp handwheel, back-moving spring is because the elastic force of self is stretched to initial position with motion bar, this punching tooling is not under there is no External Force Acting the time, back-moving spring also is stretched to initial position with motion bar, uses back-moving spring, and is simple in structure.

In above-mentioned a kind of punching tooling, the end face of described drill bit is 15 ° of inclinations, and the bottom surface of described groove is 15 ° of inclinations, and described groove and above-mentioned drill bit are complementary.Drill bit is 15 ° of inclinations, makes drill bit and diaphragm contact area less, increases the active force that diaphragm is subject to, and punching is convenient, and punching speed is fast, and the deformation quantity that diaphragm is subject to is less, and drilling precision is high, and the bottom surface of groove also is 15 °, is in order to match with drill bit.

In above-mentioned a kind of punching tooling, be connected by screw thread between described drill bit and motion bar, described upper cover and drill bit welding are connected.Drill bit is threaded with motion bar, for the diaphragm of different model, is convenient for changing the drill bit of obstructed model specification, and upper cover and drill bit welding are connected, and can reduce operating procedure, need not manually upper cover be pressed on diaphragm.

In above-mentioned a kind of punching tooling, be connected by screw thread between described subiculum and base.Subiculum is connected with whorl of base, for the diaphragm of different model, is convenient for changing the subiculum of obstructed model specification.

Compared with prior art, the punching tooling that provides of the utility model has the following advantages:

1, the subiculum that this punching tooling uses and diaphragm is complementary is diaphragm fixedly, determines the center of diaphragm, and when punching, upper cover is pushed down diaphragm, and diaphragm can not stretched inwards because of extruding, and machining accuracy is high

2, the drill bit of this punching tooling and upper cover are to be connected by welding, manually upper cover are pressed in the step on diaphragm when reducing punching, and working (machining) efficiency is high.

3, the subiculum of this punching tooling and drill bit are threaded with base and connecting rod respectively, can change subiculum and the diaphragm of different model specification for the diaphragm of different model, and the scope of application is wide.

4, this punching tooling back-moving spring is installed, the every punching once, drill bit automatically returns to initial position, production efficiency is high.
