Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 to Fig. 8 shows a kind of special-shaped punch mechanism with liftout, comprises top convex portions and bottom female mold part.Top convex portions comprises spring-loaded plunger 1, special-shaped plunger chip 2 and drift mount pad 3, and spring-loaded plunger 1 is arranged in special-shaped plunger chip 2, and special-shaped plunger chip 2 is arranged in drift mount pad 3, is undertaken fastening by stud 4 by special-shaped plunger chip 2 and drift mount pad 3.
Special-shaped plunger chip 2 center is processed with centre bore with mounting spring plunger 1, spring-loaded plunger 1 is threaded with the internal thread 21 of centre bore on special-shaped plunger chip 2 by the external screw thread 111 on himself fairlead 11, and the head of spring-loaded plunger 1 stretches out the length in cutting face, special-shaped plunger chip 2 lower end at about 5mm.Drift mount pad 3 center has through hole to install special-shaped plunger chip 2, and the cross sectional shape of through hole and the cross sectional shape of special-shaped plunger chip 2 adapt.Special-shaped plunger chip 2 and drift mount pad 3 product adopt tight fit, adopt mode of slightly knocking to be squeezed in drift mount pad 3 through hole on special-shaped plunger chip 2 top, until special-shaped plunger chip 2 upper surface is concordant with the upper end installed surface 33 of drift mount pad 3 during installation.Then, then stud 4 and the screw thread 34 on drift mount pad 3 are carried out threaded engagement, until stud 4 snaps in the groove 22 of special-shaped plunger chip 2 and compresses special-shaped plunger chip 2, thus locking special-shaped plunger chip 2.Upper end installed surface 33 and the upper mould body of drift mount pad 3 are fitted, and use screw and pin and die ontology to be connected and fixed respectively by screw hole 31, pin hole 32.
Bottom female mold part comprises die case 5, and the lower mould body that is direct and mould of the lower end installed surface 53 on die case 5 is fitted, and uses screw and pin are connected with lower mould body and fix respectively by installing hole 51, locating hole 52.Have in the middle of die case 5 special-shaped through hole with abnormal-shaped punch 2 cooperating, special-shaped through hole bottom is horn-like so that waste material 61 is discharged.
Top convex portions and bottom female mold part entirely on the center in assembling process, and according to common punching press punching require mate.
Special-shaped plunger chip 2, drift mount pad 3, die case 5 need use alloy tool steel to make, and first carry out the preliminary working of all models face, inner die cavity, and the processing of special-shaped plunger chip 2 internal thread 21; Heat-treat again, finally carry out the fine finishining of connection and compatible portion.
In the concrete course of work, the upper part of mechanism moves downward with the patrix of punching die, and the head of spring-loaded plunger 1 first contacts plate 6; Along with moving downward further of patrix, the head of spring-loaded plunger 1 will constantly compress, and have certain pressure to plate 6.Thereupon, special-shaped plunger chip 2 contacts with plate 6, and starts to carry out stamping-out to plate 6; After punched scrap 61 is cut-off, punched scrap 61 departs from from plate 6, enter die case 5, utilize the strength of spring-loaded plunger 1, directly punched scrap 61 is headed into a segment distance to die case 5, be convenient to the smooth discharge of punched scrap 61, avoid because of self-control special-shaped plunger chip 2, make not high waste material 61 jam caused of special-shaped die case 5 precision by oneself, and damage special-shaped plunger chip 2, be split up die case 5.
After waste material 61 ejects downwards by spring stick harness 1, telescopic head, also by the spring action because of its inside, is released, is returned to the state do not stressed by spring stick harness 1.If there is a small amount of tablet in die case 5 not to be pushed out, after stamping-out completes, patrix moves upward in process, spring stick harness 1 is also by the spring action because of its inside, progressively telescopic head is released, until spring stick harness 1 is separated with waste material 61, now, the head of spring stick harness 1 also can return to the state do not stressed.
The utility model can according to the jam quantity of waste material 61, select whether grind die case 5, or use the telescopic head of specific purpose tool regulating spring stick harness 1 to regulate overhang relative to special-shaped plunger chip 2 cutting face, that carrys out regulating spring stick harness 1 pair of waste material 61 ejects strength.
By reference to the accompanying drawings exemplary description is carried out to the utility model above; obvious realization of the present utility model is not subject to the restrictions described above; as long as have employed the various improvement that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all in protection domain of the present utility model without to improve.
