Abstract
The utility model discloses a single-head replaceable cold heading/stamping bearing roller punching head, which is provided with a punching head jacket. A punching head groove is arranged in the center of the punching head jacket; a process hole for replacement, communicated with the punching head groove and a lower end surface, is arranged in the center of the punching head groove; and a molding die core which is in interference fit with the punching head jacket is arranged in the punching head groove. Not only is the single-head replaceable cold heading/stamping bearing roller punching head simple in structure, but also the replacement of the die core can be carried out; the waste is reduced; resources are saved; the service life is long; and the use effect is good.
Description
Technical field
The utility model relates to a kind of cold-heading machine tool mould accessory, the single head changeable type cold-heading of using in the lathe specifically/impulse bearing roller punch.
Background technology
Existing market upper bearing (metal) cold-heading/stamping head of stamping die is monolithic mold, this mould remains in defective in concrete use procedure, the bearing roller drift in punching course because of discontinuity, because occurring easily expanding even slight crack, service life is short, prior art has seriously reduced the quality of production, has increased production cost.Simultaneously, when the bearing roller drift of making can not use, whole mould can only be thrown away, can not reuse, the waste resource.
The utility model content
The utility model provides single head changeable type cold-heading/impulse bearing roller punch, and it is not only simple in structure, can carry out core rod and change, and reduces waste, saving resource, and long service life, result of use is good.
The utility model is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is: single head changeable type cold-heading/impulse bearing roller punch, be provided with the drift overcoat, drift overcoat center is provided with the drift groove, drift groove center is provided with the replacing fabrication hole that is communicated with drift groove and lower surface, be provided with the formation die core with drift overcoat interference fit in the drift groove, the end face of formation die core flushes with the upper surface of drift overcoat, the center of formation die core is provided with the shaping groove of annular, and the shaping groove center is provided with round boss.
Two end faces of drift overcoat described in the utility model are provided with chamfering.
Drift outer casing outer wall described in the utility model is provided with holddown groove.
The utility model beneficial effect is:
1, drift overcoat and formation die core interference fit make between drift overcoat and the formation die core and produce interaction force, make the bearing roller drift offset in use a part of stamping press, the service life of lift shaft bearing roller drift.
2, drift overcoat and formation die core are split-type structural, when formation die core can't use, formation die core can be unloaded, and change, and the drift overcoat can continue to use, and save cost, reduce the wasting of resources.
3, drift puts outward and is provided with the Replacement procedure hole, can't change without this hole forming core rod.。
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is the sectional structure schematic diagram of drift overcoat of the present utility model
Fig. 3 is perspective view of the present utility model.
Among the figure: 1, drift overcoat, 101, chamfering, 102, change and use fabrication hole, 103, the drift groove, 104, holddown groove, 2, formation die core, 201, round boss, 202, shaping groove.
The specific embodiment
As shown in the figure, single head changeable type cold-heading/impulse bearing roller punch, be provided with drift overcoat 1, drift overcoat 1 center is provided with drift groove 103, drift groove 103 centers are provided with the replacing fabrication hole 102 that is communicated with drift groove 103 and lower surface, be provided with the formation die core 2 with drift overcoat 1 interference fit in the drift groove 103, the end face of formation die core 2 flushes with the upper surface of drift overcoat 1, the center of formation die core 2 is provided with the shaping groove 202 of annular, and shaping groove 202 centers are provided with round boss 201.
1 two end faces of described drift overcoat are provided with chamfering 101.
Described drift overcoat 1 outer wall is provided with holddown groove 104, is used for the installation of drift.
Single head changeable type cold-heading/impulse bearing roller punch, formed by drift overcoat 1 and formation die core 2, drift overcoat 1 and formation die core 2 are split-type structural, and formation die core 2 is solid, and both adopt interference fit to assemble, mutually extruding between the two, produce interaction force, and drift is when being used, this interaction force can be offset a part of stamping press, indirectly reduce drift consumption, promoted the service life of drift.
Drift overcoat 1 and formation die core 2 are interference fit, drift in use, formation die core 2 part losses are fast, and 1 loss of drift overcoat is slow, when formation die core 2 can't use, formation die core 2 can be unloaded, new formation die core 2 is installed again, has been saved drift overcoat 1, reduce use cost.
Drift overcoat 1 and formation die core 2 are interference fit, and drift overcoat and formation die core can adopt unlike material to make, and formation die core can adopt the high-strength impact-resistant material, promote the drift quality.
When formation die core need to be changed, can with fabrication hole formation die core be ejected by changing, improve formation die core and change efficient, change more convenient.
