Description
Technical field
The utility model relates to a kind of precision tapered roller quantitative discharging device, is a kind of precision tapered roller quantitative discharging device 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 is washed, stress relief annealing, front cleaning, Quenching Treatment, cold treatment, tempering for the first time, grind, magnetic powder inspection, superfinishing, clean, outward appearance, product inspection, size separation, sampling observation surface quality, oiling and counting packaging process, wherein four station Balance mechanisms, it is made up of four extrusion process and a shearing blanking operation, what raw material adopted is through drawing, annealing, surface-treated bearing steel disk biscuit, disk material is suspended on uncoiler, after twice alignment of straightener vertical-horizontal, by drawing-inroller, material is passed through to feed conduit successively, dead knife, after movable knife, arrive clipped position, the blank of cutting is delivered to lower four extrusion positions successively through manipulator, finally product is sent on conveyer belt outside arrival machine.
For shearing blanking operation, what adopt at present is that dead knife and movable knife are used in conjunction with, fixing due to the gap between wire rod and dead knife, movable knife and wire rod, if the method that adopts conventional little gap to shear, upper and lower two end faces of blank that obtain can be crushed, be ellipticity, two ends cylindrical has and subsides, and after the first station shaping, at both ends of the surface cylindrical, place still has significantly and subsides, to affect the quality of forging, and upsetting pressure mould is had to damage simultaneously.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of precision tapered roller quantitative discharging device 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 precision tapered roller quantitative discharging device, comprise feed mechanism, dead knife cutter hub, movable knife cutter hub and buting iron, adopt bearing steel disk wire rod, be sent to dead knife cutter hub by feed mechanism, between movable knife cutter hub and buting iron, sheared by movable knife cutter hub, its innovative point is: described dead knife cutter hub, movable knife cutter hub, and buting iron sets gradually along the direction of propulsion of wire rod, described movable knife cutter hub is made up of shell A and mold core A, described dead knife cutter hub is made up of shell B and mold core B, the mold core A of the mold core B of this dead knife cutter hub and described movable knife cutter hub and described wire rod are suitable, described movable knife cutter hub is coaxially arranged on described dead knife cutter hub top, the upper surface of the lower surface of this movable knife cutter hub and dead knife cutter hub leaves gap on the moving direction of wire rod.
Further, the upper surface of the lower surface of movable knife cutter hub and dead knife cutter hub is on the moving direction of wire rod, and this gap is 0.15mm-0.25mm.
The utility model has the advantage of: be 1. sent between dead knife cutter hub, movable knife cutter hub and buting iron by feed mechanism, sheared by movable knife cutter hub, by regulating buting iron, realize quantitative shearing Len req wire rod; 2. described in, movable knife cutter hub is coaxially arranged on described dead knife cutter hub top, the upper surface of the lower surface of this movable knife cutter hub and dead knife cutter hub leaves gap on the moving direction of wire rod, on the blank end face that makes to shear, there is the unnecessary material of a fritter, make up the deficiency of cylindrical material with this material, can prevent that movable knife from producing material end face burn in transport process with wire rod friction simultaneously; 3. the upper surface of the lower surface of movable knife cutter hub and dead knife cutter hub is on the moving direction of wire rod, and this gap is 0.15mm-0.25mm, and the product percent of pass that makes forging and stamping obtain within the scope of this reaches 99%; Pass through.
Brief description of the drawings
Fig. 1 is the structural representation of circular cone roller.
Fig. 2 is the structural representation of a kind of precision tapered roller quantitative discharging device of the present utility model.
Detailed description of the invention
As shown in Figure 2, a kind of precision tapered roller of the utility model quantitative discharging device, comprise feed mechanism, dead knife cutter hub, movable knife cutter hub and buting iron 4, adopt bearing steel disk wire rod 5, be sent between dead knife cutter hub, movable knife cutter hub and buting iron 4 by feed mechanism, sheared by movable knife cutter hub
Described dead knife cutter hub, movable knife cutter hub and buting iron 4 set gradually along the direction of propulsion of wire rod 5, described movable knife cutter hub is made up of shell A6 and mold core A 7, described dead knife cutter hub is made up of shell B8 and mold core B 9, the mold core B 9 of this dead knife cutter hub is suitable with described wire rod 7 with the mold core A 7 of described movable knife cutter hub, described movable knife cutter hub is coaxially arranged on described dead knife cutter hub top, and the upper surface of the lower surface of this movable knife cutter hub and dead knife cutter hub leaves gap H on the moving direction of wire rod.
Following table is depicted as the relation of gap H and product percent of pass
| Gap H(mm) | 0.1 | 0.15-0.25 | 0.3 |
| Stock outward appearance after shearing | Fast pig's tongue, wire rod end face burn | ||
| Product appearance after upsetting pressure | Burr | Crackle | |
| Upsetting pressure mould | Mould damage | ||
| Product percent of pass | 95% | 99% | 90% |
As seen from the above table, gap H is arranged on 0.15mm-0.25mm, and the qualification rate of product is high, and does not damage mould.
When use, be sent between dead knife cutter hub, movable knife cutter hub and buting iron 4 by feed mechanism, sheared by movable knife cutter hub, by regulating the distance of buting iron 4 to movable knife cutter hub, realize quantitative shearing Len req wire rod.
