Abstract
The utility model provides a multi-combination replaceable type cold heading/punching bearing roller plunger chip, consisting of a through straight jacket and two shaping mould cores, wherein the through straight jacket is sheathed on the outer sides of the two shaping mould cores and further is in interference fit with the shaping mould cores; the outer end faces of the two shaping mould cores are aligned with the end face of the through straight jacket; moreover, a circular shaping recess is formed in the center of the end face of each shaping mould core; and the center of each shaping recess is provided with a round boss. Therefore, the multi-combination replaceable type cold heading/punching bearing roller plunger chip is not only simple in structure, but also available for the replacement of the mould cores; and in addition, the waste is decreased, the resource is saved and the use effect is good.
Description
Technical field
The utility model relates to a kind of cold-heading machine tool mould accessory, many combinations 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, and 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 many combination changeable types 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 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: make up changeable type cold-heading/impulse bearing roller punch more, formed by perfectly straight overcoat and two formation die cores, perfectly straight overcoat be enclosed within two formation die cores outside and with the formation die core interference fit, the outer face of two formation die cores is equal with perfectly straight overcoat end face, and be provided with the shaping groove of annular at the center of this formation die core end face, the shaping groove center is provided with round boss.
The edge of two end faces of perfectly straight overcoat described in the utility model is provided with chamfering.
The sidewall of perfectly straight overcoat described in the utility model is provided with the steam vent that connects perfectly straight overcoat inside and outside wall.
Be provided with pad between two formation die cores described in the utility model.
Perfectly straight outer casing outer wall described in the utility model is provided with holddown groove.
The utility model beneficial effect is:
1, perfectly straight overcoat and formation die core interference fit make between perfectly straight 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, perfectly straight 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 perfectly straight overcoat can continue to use, and save cost, reduce the wasting of resources.
3, perfectly straight outer putting is provided with steam vent, and the air that produces in dress core rod process is discharged by steam vent, prevents from producing the air mineralization pressure between two core rod bottom surfaces, and two core rod bottom surfaces are fitted tightly.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of embodiment 1 of the present utility model.
Fig. 2 is the sectional structure schematic diagram of embodiment 2 of the present utility model.
Fig. 3 is perspective view of the present utility model.
Among the figure: 1, perfectly straight overcoat, 101, chamfering, 102, steam vent, 103, holddown groove, 2, formation die core, 201, round boss, 202, shaping groove, 203, pad.
The specific embodiment
As shown in the figure, many combination changeable types cold-heading/impulse bearing roller punch, formed by perfectly straight overcoat 1 and two formation die cores 2, perfectly straight overcoat 1 be enclosed within two formation die core 2 outsides and with formation die core 2 interference fit, the outer face of two formation die cores 2 is equal with perfectly straight overcoat 1 end face, and be provided with the shaping groove 202 of annular at the center of these formation die core 2 end faces, shaping groove 202 centers are provided with round boss 201.
The edge of 1 two end faces of described perfectly straight overcoat is provided with chamfering 101.
The sidewall of described perfectly straight overcoat 1 is provided with the steam vent 102 that connects perfectly straight overcoat 1 inside and outside wall.
Be provided with pad 203 or do not need pad between described two formation die cores 2.
Described perfectly straight overcoat 1 outer wall is provided with holddown groove 103, is used for installing drift, and the shape of holddown groove and size are decided according to installation situation.
Three combination changeable type cold-heading/impulse bearing roller punchs, formed by perfectly straight overcoat 1 and two formation die cores 2, perfectly straight 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.
Perfectly straight overcoat 1 and formation die core 2 are interference fit, and perfectly straight 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.
Perfectly straight overcoat 1 and formation die core 2 are interference fit, drift in use, formation die core 2 part losses are fast, and perfectly straight overcoat 1 loss 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 perfectly straight overcoat 1, reduce use cost.
Embodiment 1
A drift is provided with two formation die cores, when the one side service failure, drift can be turned the formation die core that uses another side, two formation die cores are split type setting, and an end of two formation die cores fits, and perfectly straight outer putting is provided with steam vent, steam vent is arranged on the junction of two formation die cores, the air that produces in dress core rod process is discharged by steam vent, prevents from producing the air mineralization pressure between two core rod bottom surfaces, and two core rod bottom surfaces are fitted tightly.
A drift is provided with two formation die cores, when the one side service failure, drift can be turned the formation die core that uses another side, two formation die cores are split type setting, between two formation die cores, be provided with pad, the pad center is provided with an aperture that is used for exhaust, and pad is used for reducing the impulsive force that two formation die cores produce because of mutual extruding in use procedure.
Put outside perfectly straight and be provided with steam vent, steam vent is located at any one formation die core and pad junction, and the air that produces in dress core rod process is discharged by steam vent, prevents from producing air between two core rod bottom surfaces, mineralization pressure.
