Abstract
The invention discloses a flanged shaft connecting hole spline extrusion die structure which reduces punch break risk. The flanged shaft connecting hole spline extrusion die structure comprises a punch sleeve and a punch seat connected with the punch sleeve, wherein a guiding groove is formed in the lower end of the punch seat; a punch matched with flanged shaft connecting hole is arranged below the punch seat; a chamber matched with the guiding groove is arranged on the upper end of the punch; a screw is arranged in the middle of the punch; a guiding head is arranged on the lower end of the punch; a female die, a lower female die and a pressure block are arranged sequentially outside a flanged shaft workpiece from upper to lower; a material returning ejection rod is arranged in the middle of the pressure block; and a material returning boss and a punch returning ejection rod are arranged on the upper end of the material returning ejection rod.
Description
Technical field
The present invention relates to a kind of flange shaft connecting hole spline structure of extrusion.
Background technology
Need to process the spline of flange shaft connecting hole in flange shaft process, conventional mold and punching head adopts integral type, the axiality of drift and upper and lower mould will be debugged before extruding spline, otherwise drift is subject to radial load, easily fracture accident, increases manufacturing cost, and safely threat is produced to operator, and debug length consuming time, and once drift fracture, reforming, drift feed consumption is large, the cycle is long.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of flange shaft connecting hole spline structure of extrusion reducing drift risk of breakage.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: flange shaft connecting hole spline structure of extrusion, comprise: drift overlaps the punch holder be connected with drift cover, at the lower end direction recess of described punch holder, the drift cooperatively interacted with it with flange shaft connecting hole is provided with in the below of described punch holder, the chamfering cooperatively interacted with direction recess is provided with in the upper end of drift, the middle part of drift is provided with screw thread, the lower end of drift is provided with guiding head, the outside of flange shaft workpiece is disposed with die from top to bottom, lower cavity die and pressure block, the middle part of described pressure block is provided with material returned push rod, be provided with material returned boss in the upper end of described material returned push rod and move back drift push rod.
Advantage of the present invention is: above-mentioned flange shaft connecting hole spline structure of extrusion, solid punch is decomposed into punch holder and drift, drift intensity after shortening increases greatly, reduce the risk of drift fracture, in conjunction with the material returning structure of material returned bar, make to produce assembling and production process more simple and fast, eliminate the factor producing time waste product because solid punch axiality is bad simultaneously, be applicable to cold extrusion and product that is higher or the thinner frangibility of upper punch is required to upper and lower mould axiality.
Accompanying drawing explanation
Fig. 1 is the structural representation of flange shaft connecting hole spline structure of extrusion of the present invention.
In figure: 1, drift cover, 2, punch holder, 3, direction recess, 4, flange shaft connecting hole, 5, drift, 6, chamfering, 7, screw thread, 8, guiding head, 9, flange shaft workpiece, 10, die, 11, lower cavity die, 12, pressure block, 13, material returned push rod, 14, material returned boss, 15, move back drift push rod.
Detailed description of the invention
Particular content of the present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, flange shaft connecting hole spline structure of extrusion, comprise: drift cover 1 overlaps 1 punch holder be connected 2 with drift, at the lower end direction recess 3 of described punch holder 2, the drift 5 cooperatively interacted with it with flange shaft connecting hole 4 is provided with in the below of described punch holder 2, the chamfering 6 cooperatively interacted with direction recess 3 is provided with in the upper end of drift 5, the middle part of drift 5 is provided with screw thread 7, guiding head 8 is provided with in the lower end of drift 5, the outside of flange shaft workpiece 9 is disposed with die 10 from top to bottom, lower cavity die 11 and pressure block 12, the middle part of described pressure block 12 is provided with material returned push rod 13, be provided with material returned boss 14 in the upper end of described material returned push rod 13 and move back drift push rod 15.
As shown in Figure 1, flange shaft connecting hole spline structure of extrusion, flange shaft workpiece 9 is placed in after in die 10, the guiding head 8 of drift 5 lower end is inserted in the flange shaft connecting hole 4 in flange shaft-like work 9, make drift 4 can standing upright, start to carry out crowded spline to the flange shaft connecting hole 4 of flange shaft workpiece 9 after drift cover 1 and punch holder 2 come downwards to the upper-end contact of baseplane and drift 5 with slider of oil press, punch holder 2 is with after slide block backhaul, and drift 5 is still embedded in flange shaft workpiece 9; During the material returned, drift 5 first ejects by the drift push rod 15 that moves back of material returned push rod 13 upper end, and flange shaft workpiece 9 ejects by material returned boss 14.
Above-mentioned flange shaft connecting hole spline structure of extrusion, solid punch is decomposed into punch holder and drift, drift intensity after shortening increases greatly, reduce the risk of drift fracture, in conjunction with the material returning structure of material returned bar, make to produce assembling and production process more simple and fast, eliminate the factor producing time waste product because solid punch axiality is bad simultaneously, be applicable to cold extrusion and product that is higher or the thinner frangibility of upper punch is required to upper and lower mould axiality.
