Description
Technical field
The utility model relates to a kind of taper roller blanking special metals cutter, is a kind of taper roller blanking special metals cutter that can improve product percent of pass specifically.
Background technology
Bearing roller is the important component part of bearing, has taper roller, spherical roller, cylindrical roller etc., and it is widely used in all kinds of machinery, has especially application more widely in automotive axle, wheel hub.
As shown in Figure 1, it is conical that taper roller is, and the two ends up and down of its circular cone are respectively large end 1 and small end 2, on large end end face, is also provided with pit 3.
At present, the manufacturing process flow of taper roller is: four station high speed cold-heading moldings, hot acid are washed, stress relief annealing, front cleaning, Quenching Treatment, cold treatment, tempering for the first time, grinding, magnetic powder inspection, superfinishing, cleaning, outward appearance, product inspection, size separation, sampling observation surface quality, oiling and counting packaging process, four station Balance mechanisms wherein, it is comprised of four extrusion process and a shearing blanking operation.
For shearing blanking operation, what adopt at present is that dead knife and movable knife are used in conjunction with, the lower surface of movable knife and the upper surface of dead knife are level, when shearing wire rod, the stock that shearing obtains produces Bending Deformation, and upper and lower two end faces meeting out-of-flatness, generation burr damage cutter hub simultaneously.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of bearing roller shearing blanking movable knife that can improve product percent of pass and strengthen upsetting pressure die life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of taper roller blanking special metals cutter, described cutter comprises movable knife cutter hub and lower dead knife cutter hub, adopt bearing steel disk wire rod, by feed mechanism, be sent between upper movable knife cutter hub and lower dead knife cutter hub, by upper movable knife cutter hub, coordinate shearing with lower dead knife cutter hub, its innovative point is: described upper movable knife cutter hub is comprised of shell A and mold core A, described lower dead knife cutter hub is comprised of shell B and mold core B, the mold core A of the mold core B of this lower dead knife cutter hub and described upper movable knife cutter hub and described wire rod are suitable, described upper movable knife cutter hub is coaxially arranged on described lower dead knife cutter hub top, on this, coordinate the working face of shearing with lower dead knife cutter hub be two symmetrical outer arcuate faces to movable knife cutter hub.
Further, the angle of described outer arcuate face and horizontal plane is 2 °.
The utility model has the advantage of: upper movable knife cutter hub coordinates the working face of shearing with lower dead knife cutter hub be two symmetrical outer arcuate faces, make the stock flatness after shearing high, and can tool setting not there is damage, strengthened the service life of cutter; The angle of outer arcuate face and horizontal plane is 1.5 °-2.5 °, makes the stock quality of shearing better, has improved the qualification rate of product after upsetting pressure.
Accompanying drawing explanation
Fig. 1 is the structural representation of circular cone roller.
Fig. 2 is the structural representation of a kind of taper roller blanking special metals cutter of the present utility model.
The specific embodiment
As shown in Figure 2, a kind of taper roller blanking of the utility model special metals cutter, comprise movable knife cutter hub and lower dead knife cutter hub, adopt bearing steel disk wire rod 4, by feed mechanism, be sent between upper movable knife cutter hub and lower dead knife cutter hub, by upper movable knife cutter hub, coordinate shearing with lower dead knife cutter hub, described upper movable knife cutter hub is comprised of shell A5 and mold core A 6, described lower dead knife cutter hub is comprised of shell B7 and mold core B 8, the mold core B 8 of this lower dead knife cutter hub is suitable with described wire rod 4 with the mold core A 6 of described upper movable knife cutter hub, described upper movable knife cutter hub is coaxially arranged on described lower dead knife cutter hub top, on this, coordinate the working face of shearing with lower dead knife cutter hub be two symmetrical outer arcuate faces 9 to movable knife cutter hub.
In the present embodiment, preferred, the angle α of described arcwall face and horizontal plane is 1.5 °-2.5 °, and in the present embodiment, angle α is 2 °, makes the stock quality of shearing better, has improved the qualification rate of product after upsetting pressure.
Following table is depicted as the relation of angle α and product percent of pass
| Angle α (°) | 1 | 1.5-2.5 | 3 |
| Stock outward appearance after shearing | Surface has | There is radian on surface | |
| Cutter | Tool surface has wearing and tearing | ||
| Product appearance after upsetting pressure | Burr | Crackle | |
| Product percent of pass | 95% | 99% | 90% |
As seen from the above table, α is arranged on 1.5 °-2.5 °, and the qualification rate of product is high, and does not damage cutter.
During use, by wire rod 4 being passed successively to the mold core B 8 of lower dead knife cutter hub and the mold core A 6 of upper movable knife cutter hub, the upper movable knife cutter hub that then slides, completes the shearing to wire rod 4.
Claims (2)
1. a taper roller blanking special metals cutter, described cutter comprises movable knife cutter hub and lower dead knife cutter hub, adopt bearing steel disk wire rod, by feed mechanism, be sent between upper movable knife cutter hub and lower dead knife cutter hub, by upper movable knife cutter hub, coordinate shearing with lower dead knife cutter hub, it is characterized in that: described upper movable knife cutter hub is comprised of shell A and mold core A, described lower dead knife cutter hub is comprised of shell B and mold core B, the mold core A of the mold core B of this lower dead knife cutter hub and described upper movable knife cutter hub and described wire rod are suitable, described upper movable knife cutter hub is coaxially arranged on described lower dead knife cutter hub top, on this, coordinate the working face of shearing with lower dead knife cutter hub be two symmetrical outer arcuate faces to movable knife cutter hub.
