The gasket punching die comprises an upper die, a lower die, guide columns connected with the upper die and the lower die and a punching head, wherein a push part is arranged on the upper die; the punching head is connected with the push part through a punching head seat; a punching slot is arranged on the part, which is opposite to the punching head, of the lower die; and the gasket punching die also comprises an upper blade connected with the push part and a lower blade arranged on the lower die. By adopting the technical scheme, the technical problems can be effectively solved.

Description

A kind of pad punch die

Technical field

The utility model belongs to mechanical equipment technical field, relates to a kind of pad punch die.

Background technology

Pad is a kind of parts that often relate in the frame for movement, and the production of pad normally with the steel plate cutting, is carried out punching to the steel plate after the cutting then; Generally, these operations are all by accomplishing, because manually-operated punching effect is difficult to guarantee manually; At present the equipment that punching occurred much being specifically designed to is arranged also, for example, Chinese utility model patent " pad hole punched device " (patent No. ZL 200720032812.X) discloses a kind of pad hole punched device; This device comprises pedestal, and the centre of pedestal is provided with groove, has through hole and lower through-hole in the last lower base of groove; Pedestal is connected with depression bar through connecting rod, is provided with jumper bar between depression bar and the pedestal, jumper bar overcoat back-moving spring; Jumper bar passes the fairlead in the through hole, and the lower end of jumper bar is connected with upper blade, and the upper surface of groove is equipped with demoulding baffle plate; The lower surface of groove is equipped with down towards sword in the middle of the former seat is installed, and is installed in same axle center towards sword and lower through-hole down; Following to sword and the same axle center of upper blade, and the external diameter of upper blade equates with following internal diameter towards sword.

This device has promoted the quality of pad, has solved following problem: pad out-of-flatness, problem such as deformable folding is serious, and interchangeability is poor, and burr is many, and outward appearance is nonstandard.

The utility model content

Though more existing devices can solve the problem of the difficult quality guarantee that manually-operated brings; But the utility model is found existing pad hole punched device and basically all two processes of punching and cutting is separated; Also be that the pad hole punched device can only carry out punch operation, so just reduced the efficient that pad is made greatly, thus; The utility model provides a kind of pad punch die, and this punch die can carry out punching and cutting fully simultaneously.

Said a kind of pad punch die; The lead and the drift that comprise upper die and lower die, connection upper die and lower die; Patrix is provided with push mechanism; Drift is connected with push mechanism through punch holder, and counterdie and drift opposite position are provided with the punching groove, it is characterized in that said pad punch die also comprises the cutter that is connected with push mechanism and is arranged on the bottom knife on the counterdie.

Drift and cutter promote by push mechanism, therefore, tablet put into counterdie after, just can be along with the promotion of push mechanism is carried out punching and cutting to tablet respectively by drift and cutter.

For strengthening the linkage of cutter and punching, said cutter is connected with push mechanism through punch holder.

Realization is carried out punching and is sheared to tablet after, also need consider tablet is carried out the sequencing of punching and shearing, this point can not be ignored; In practice, if the utility model discovery is carried out punching and cutting process simultaneously, so because when shearing; Cutter has a power of pullling to insert orientation to tablet, drift receive easily this power effect and by being broken, therefore one preferably scheme be not make the process of cutting and punching superimposed; Also be that the technical staff can make punch process carry out earlier; Then cut again, cutting process is carried out earlier, then carry out punching again.

The utility model has provided a kind of structure of punching again that can realize cutting then earlier, and promptly the cutter blade is in same plane from bottom knife farthest and drift bottom surface.Thereby after cutter was accomplished the cutting to tablet, drift just carried out punching immediately.

Certainly, said cutter blade place straight line and bottom knife blade place straight line intersect, so that cutting.

The specific embodiment

Embodiment

See Fig. 1 to 4; A kind of pad punch die comprises patrix 6, counterdie 11, connects the lead 10 and the drift 8 of patrix 6 and counterdie 11, and patrix 6 is provided with and promotes piston 1; Punch holder 7 is connected with promotion piston 1; Drift 8 is connected with punch holder 7 through punch holder contiguous block 21, and counterdie 11 is provided with punching groove 20 with drift 8 opposite positions, and said pad punch die also comprises cutter 3 and is arranged on the bottom knife 5 on the counterdie 11; Said cutter 3 is fixed on the punch holder 7 through cutter fixed block 2, and cutter fixed block 2 is blocked by the block that blocks pad 4.

Said cutter 3 blades are with respect to bottom knife 5 edge tilted; And cutter 3 blades are in same plane from bottom knife 5 farthest and drift 8 bottom surfaces; Like this, after the shearing that cutter 3 and bottom knife 5 are accomplished tablet 9, drift 8 begins tablet 9 is carried out punching immediately; Avoid producing the power of pullling to cutter 3 directions that causes by shearing, thereby drift 8 can not receive the effect of this power yet and broken.

Said punch holder contiguous block 21 is provided with punch holder contiguous block 21 is fixed on fixing hole 12 on the punch holder 7, the fixedly bore of the punch 13 and the locating hole 14 of drift 8; Bore of the punch 13 can be arranged to a plurality of with the distance between adjusting drift 8 and cutter 3 shearings place according to reality processing needs, thereby can be used for producing the pad of different size.

More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
