Description
Technical field
This utility model relates to machinery manufacturing technology field, especially a kind of die-cut punch of modified model.
Background technology
Mould is punched in actual production very important effect, and punch is the important component part of mould, and by coordinating with die cutter, cutting goes out the product of required form, existing integral-typed punch, and waste of material is serious, and service life is short.
Summary of the invention
In order to overcome the deficiency that existing integral-typed punch waste of material is serious and service life is short, this utility model provides a kind of die-cut punch of modified model, die-cut punch by bi-material double-layer structure pattern, materials do not affect the using effect of punch while saving, and increase regrinding number of times, cutting die cutter block can be individually replaced, improve the service life of punch, reduce cost.
This utility model solves its technical problem and be the technical scheme is that a kind of die-cut punch of modified model, including punch cutter and punch edge bearing plate, punch cutter is fixedly connected on punch edge bearing plate by screw, punch cutter is cut into four pieces, the incision band of punch cutter is gradient, is provided with inclination angle at the cutting edge of punch cutter.
According to another embodiment of the present utility model, the incision gradient farther including punch cutter is 5 °.
According to another embodiment of the present utility model, farther including inclination angle at the cutting edge of punch cutter is 2 °.
According to another embodiment of the present utility model, farther including uniform six passages on punch cutter, passage runs through punch edge bearing plate.
According to another embodiment of the present utility model, farther including punch cutter material is high-speed steel.
According to another embodiment of the present utility model, farther including punch edge bearing panel material is pre-hardening plastic die steel.
The beneficial effects of the utility model are, by being provided with the structure of upper and lower two-layer bi-material, closely combine together by 4 punch cutter blocks, have both saved material, the most do not affected using effect；Punch cutter block is convenient for changing and reconditioning simultaneously, improves the service life of punch, reduces cost.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
Fig. 3 is top view of the present utility model.
1. punch cutter, 2. edge bearing plate, 3. screw, 4. passage in figure.
Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of die-cut punch of modified model, including punch cutter 1 and punch edge bearing plate 2, punch cutter 1 is fixedly connected on punch edge bearing plate 2 by screw 3, punch cutter 1 is cut into four pieces, the incision band of punch cutter 1 is gradient, it is provided with inclination angle at the cutting edge of punch cutter 1, the incision gradient of punch cutter 1 is 5 °, at the cutting edge of punch cutter 1, inclination angle is 2 °, uniform six passages 4 on punch cutter 1, and passage 4 runs through punch edge bearing plate 2, punch cutter 1 material is high-speed steel, and punch edge bearing plate 2 material is pre-hardening plastic die steel.
This punch preparation process is first to be holed by punch cutter 1, then cuts four pieces of hypotenuses, then the spelling of four pieces of edges is one and is integrally attached on punch edge bearing plate 2, and slow wire feeding cuts overall dimensions.During declivous cutting edge Dies ' Blanking, owing to cutting edge is to tilt, during stamping-out, cutting edge is not to cut simultaneously, but the most die-cut material, this reduces die-cut cross-sectional area, thus reduce blanking pressure, so the punch of bowl cover die cutting die is made declivous cutting edge, die is made flat edge, when designing oblique sword, it should be noted that make oblique sword be arranged symmetrically with, other effect that cutting edge tilts: 1. reduce the negative pressure between concave-convex mold, producing negative pressure during concave-convex mold Guan Bi, bringing out so easily bowl cover complete for stamping-out being held when concave-convex mold separates；2. increase blanking size.
The advantage that inlaid type made by punch cutter 1: increasing with die gap due to abrasion after a period of time that works when punch cutter 1 is for monoblock type, cause blanking to have burr or the problem that can't cut, now gap cannot adjust, and punch cutter 1 is scrapped；If working when punch cutter is inlaid type, a period of time occurs that gap increases problem, can unclamp screw 3 to external-adjuster cutter block, fix screw 3 after being transferred to reasonable clearance again, and punch cutter 1 can be continuing with, and when one of punch cutter 1 tipping damages, can be individually replaced.
Otch (four cutter block contact surfaces) makes the reason of inclination: when using inlaid type, respective cut tilts, when otch is vertical when, four cutter blocks first unload any block and can lift down, that is after four cuttves are packaged on convex template, stationarity is bad, has one piece to loosen and arises that blanking quality problems；When otch makes inclination, four cutter blocks will be stuck mutually, as long as last that fixing cutter block is motionless, other cutter block would not move, thus increases cutter block fixed performance on convex template, it is ensured that blanking quality.
Described above it is merely exemplary for this utility model; and nonrestrictive, those of ordinary skill in the art understand, in the case of the spirit and scope limited without departing from claims; many amendments, change or equivalence can be made, but fall within protection domain of the present utility model.
