Abstract
The utility model discloses a double-head replaceable cold heading/stamping bearing roller punching head, and relates to a die fitting of a cold heading machine tool. The double-head replaceable cold heading/stamping bearing roller punching head consists of a punching head jacket and a molding die core; the punching head jacket is sleeved at the outer side of the molding die core and is in interference fit with the molding die core; a ring-shaped molding groove I and a circular molding groove II are respectively arranged in the center of two end surfaces of the molding die core; and a circular boss is arranged in the center of the molding groove I. Not only is the double-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 double end changeable type cold-heading of using in the lathe specifically/impulse bearing roller punch.
Background technology
Roller bearing is a kind of as bearing, be widely used in the fields such as various big machineries, vehicle, roller in the roller bearing utilizes pressing to produce in the prior art, first material is made diel, then the shape of mould and the form fit of roller to be processed use drift that material is squeezed into predetermined shape.
At present, market upper bearing (metal) cold-heading/stamping die head 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, has now seriously to have 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 double end 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 the 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: double end changeable type cold-heading/impulse bearing roller punch, formed by drift overcoat and formation die core, the drift overcoat be enclosed within the formation die core outside and with the formation die core interference fit, the center of two end faces of formation die core is respectively equipped with shaping groove I and the circular shaping groove II of annular, and shaping groove I center is provided with round boss.
Two end faces of drift overcoat described in the utility model are provided with chamfering.
The outer wall of drift overcoat 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.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is perspective view figure of the present utility model.
Among the figure: 1, drift overcoat, 101, chamfering, 102, holddown groove, 2, formation die core, 201, round boss, 202, the shaping groove I, 203, the shaping groove II.
The specific embodiment
As shown in the figure, double end changeable type cold-heading/impulse bearing roller punch, formed by drift overcoat 1 and formation die core 2, drift overcoat 1 be enclosed within formation die core 2 outsides and with formation die core 2 interference fit, the center of two end faces of formation die core 2 is respectively equipped with shaping groove I 202 and the circular shaping groove II 203 of annular, and shaping groove I 202 centers are provided with round boss 201.
1 two end faces of described drift overcoat are provided with chamfering 101.
The outer wall of described drift overcoat 1 is provided with holddown groove 102, is used for drift is installed, and the shape size of holddown groove can be made according to the drift installation situation.
Double end 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, adopt interference fit to assemble, mutually extruding produces interaction force between the two, and drift is when being used, this interaction force can be offset a part of stamping press, indirectly reduces drift consumption, has promoted the service life of drift.
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.
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.
Claims (3)
