Description
Technical field
The utility model is related to a kind of Cold header bed dieparts, specially a kind of two-sided punch.
Background technology
Roller bearing is the rolling bearing for making rolling element with short cylindrical, circular cone or drum-shaped roller.Mainly there is centripetal short circle
The structural shapes such as column roller, double-row spherical roller, taper roller and thrust roller.Roller in roller bearing is in existing skill
It is to be produced using pressing in art, material is first made to the shape of stamping die, the shape of mold and roller to be processed
Match, material is then squeezed into scheduled shape using punch.
At present, market upper bearing (metal) cold-heading/punch used in stamping die is process after cutting by bar, punch one end
For forming recess, the other end is installation end to be mounted in punch holder, is become after use after a period of time, forming recess exists
The requirement of processing has been not achieved in the defects of shape, crackle, accuracy decline, just needs to abandon punch at this time, such punch makes
It is relatively low with rate, cause certain waste；Moreover, during punch is processed by bar, the meeting between two punches in bar
Certain clout is generated, the utilization rate of bar can be reduced again in this way.
Utility model content
The purpose of this utility model is to provide a kind of two-sided punch, improves the utilization rate of bar and punching used in punch processing
The utilization rate of head, and then material is saved, reduce production cost.
In order to solve the above-mentioned technical problem, technical solution is used by the utility model：A kind of two-sided punch, two-sided punching
Head ontology is cylinder, symmetrical cavity is machined with respectively at the axial both ends of two-sided punch ontology, at the center of cavity bottom
Position is equipped with protrusion, and annular convex platform, the center of circle of annular convex platform and the cavity are circumferentially machined at the middle part of two-sided punch ontology
The center of circle be respectively positioned on the central axis of two-sided punch ontology, circumferentially respectively set at the edge at annular convex platform axial direction both ends
There is annular slope, the inclined direction of two annular slopes positioned at the both sides of annular convex platform on two-sided punch ontology on the contrary, be respectively provided with
Around the two-sided punch ontology technology groove of one week, slot bottom one end of technology groove is on the end face of annular convex platform, the other end and double
Inclined surface is formed between the side of face punch ontology.
Further, the height of the protrusion is less than the depth of cavity.
The protrusion is cylindrical.
Further, the angle of inclination of the annular slope is 45 °.
Further, the edge at the axial both ends of the two-sided punch ontology is machined with chamfering respectively.
The chamfering is 30 °.
Further, the cavity is circular groove shape.
Compared with prior art, the beneficial effects of the utility model are：
First, the utility model is machined with symmetrical cavity at the both ends of punch respectively, so in actual use, when
When the cavity of wherein one cannot be used continuously, the other end that can replace punch is continuing with, and can thus improve punch
Utilization rate, furthermore, the punch of the utility model is during processing, it is possible to reduce the surplus that bar cutting generates and carries
The utilization rate of high bar, so play the role of save material reduce cost.
Secondly, the middle part of punch is equipped with annular convex platform in the utility model, and the punch ontology of annular convex platform and both sides is formed
Step structure, after being installed in punch holder again in this way, which can play the role of fast accurate positioning, prevent
The axial float of punch, and can interact with punch holder, the stamping press suffered by a part of punch is offset, improves making for punch
Use the service life；Moreover, because annular convex platform is arranged on the middle part of punch, after punch is installed, punch is located at the part in punch holder
Length is more than the length that punch is exposed, and therefore, can also improve punch holder in use in radial directions to the pact of punch
Beam force.

Fig. 1 is the structure diagram of the utility model；
It is marked in figure：1st, two-sided punch ontology, 2, cavity, 3, protrusion, 4, annular convex platform, 5, technology groove, 6, annular slope.
Specific embodiment
Below in conjunction with the accompanying drawings, by specific embodiment, the technical solution of the utility model is further described.
As shown in the figure, a kind of two-sided punch, the cylindrical being process by bar, axial the two of two-sided punch ontology 1
The edge at end is circumferentially machined with the chamfering in 30 ° respectively, and the center at the two-sided axial both ends of punch ontology 1 then processes respectively
There is symmetrical cavity 2,2 rounded slot of cavity is equipped with tubular raised 3 in the center of 2 bottom of cavity, protrusion 3
Highly it is less than the depth of cavity 2, the specific size of the cavity 2 according to processing select, two-sided punch ontology 1
Middle part circumferentially processes annular convex platform 4, and about the annular convex platform 4 axisymmetricly, the annular convex platform 4 is same with cavity 2 for the cavity 2
Axis, the i.e. center of annular convex platform 4 and the center of cavity 2 are respectively positioned on the central axis of two-sided punch ontology 1, positioned at annular convex platform
4 both sides are on two-sided punch ontology 1 rotating around the two-sided punch ontology one annular technology groove 5 of processing in 1 one weeks, technology groove 5
Diameter be less than the diameter of two-sided punch ontology 1, and an annular is circumferentially respectively processed at the edge at the axial both ends of annular convex platform 4
Inclined-plane 6, the inclined direction of two annular slopes 6 is on the contrary, angle of inclination is 45 °, and slot bottom one end of technology groove 5 is vertically pushed up in the axial direction
On the end face of annular convex platform 4, the other end then forms an annular inclined surface between the side of two-sided punch ontology 1.
In the embodiment above, the shape of protrusion 3 is not limited to cylindrical, or other shapes, it is described
Chamfering and the angle of annular slope can also have other selections, it is not limited to the limitation of above example.
