Abstract
The utility model discloses a two-way feeding worm rod hobbing cutter, which is shaped like a circular ring as a whole, wherein a plurality of main cutting edges and assistant cutting edges are convexly arranged on the circumferential surface of the hobbing cutter at equal intervals in the circumferential direction; and in the axial line direction of the hobbing cutter, first feeding cutting edges are arranged at the outer sides of the main cutting edges while second feeding cutting edges are arranged at the outer sides of the assistant cutting edges. After the two-way feeding worm rod hobbing cutter is used, both sides of the cutting edges of the worm rod hobbing cutter are abraded evenly; and the worm rod hobbing cutter can be utilized sufficiently. Therefore, the manufacturing cost is lowered greatly, and the machining numbers of the worm rod hobbing cutter can be increased by times. In addition, the usage rate of the rod hobbing cutter is increased by times and the service life of the rod hobbing cutter is prolonged by times.
Description
Technical field:
The utility model relates to a kind of two-way feed worm hob.
Background technology:
The characteristics of worm hob design: because of the worm spiral lift angle very large, need the whole length by workpiece in the hobboing cutter process, need simultaneously whole rolling cuts during the cutter rolling cut, the time of processing whole worm screw is relevant with the length of cutter, so tool length goes out completely to design as shortest length take rolling cut.
The external form of former worm hob design only has the monolateral feeding cutting edge that has, during the rolling cut feeding, cutter can only be from a direction feeding, because the length of hobboing cutter is a complete tooth pitch, be difficult for long, so the main cutting edge that hobboing cutter can't be avoided having worn and torn by moving the cutter mode is because cutter can't move cutter, for guaranteeing the precision of product, must carry out sharpening after the worm hob wearing and tearing, the service life of worm hob is very limited.
Analyze from the worm screw process, in the rolling cut process, the both sides abrasion condition of main cutting edge is inconsistent.Because worm hob is to enter from an end-grain cutting when rolling cut, the other end cuts out, one side of cutting edge is that the main cutting edge wearing and tearing are more serious, because be that most surplus needs cutting when rolling cut, and opposite side is front cutting edge, because not participating in most processing, be that processing is repaired by tooth section during cutting, so wearing and tearing are less.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of two-way feed worm hob, manufacturing cost reduces greatly, and the processing number of packages of worm hob obtains increase at double, and utilization rate, the life-span of worm hob all are able to increase at double simultaneously.
The utility model technical solution problem adopts following technical scheme:
A kind of two-way feed worm hob, described hobboing cutter integral body is annular, along the circumferential direction interval etc. is arranged with a plurality of outstanding main cutting edges and front cutting edge on the periphery of hobboing cutter, on the axis direction of hobboing cutter, the outside of described main cutting edge is provided with the first feeding cutting edge, and the outside of described front cutting edge is provided with the second feeding cutting edge.
A plurality of described main cutting edges along the circumferential direction round on the periphery of hobboing cutter, and are interval etc. and minute distribute; A plurality of described front cutting edges and a plurality of described main cutting edge are distribution side by side on the axis direction of hobboing cutter.
The utility model worm hob arranges respectively the feeding cutting edge in the both sides near end face, and each feeding cutting edge is the tapering cutting edge, by changing the direction of rotation of worm hob, realizes the processing of two-way feed mode in machining.Be the less opposite side of wearing and tearing of main cutting edge because participating in the cutting edge that cuts use, the wearing and tearing of cutting edge are less, so the worm accuracy after processing is guaranteed.The cone of tangents degree of the other end by increasing worm hob realizes that worm hob enters cutting from an other end.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the use of process two-way feed worm hob, cutting edge two lateral wearings of worm hob are more even, simultaneously, this two-way feed formula worm hob makes worm hob can access sufficient utilization, the large reduction of manufacturing cost, the processing number of packages of worm hob obtains increase at double, and utilization rate, the life-span of worm hob all are able to increase at double simultaneously.
2, the utility model worm hob low cost of manufacture, economical and practical, be beneficial to popularization.
Description of drawings:
Fig. 1 is the front view of the utility model hobboing cutter; Fig. 2 is the cutaway view of hobboing cutter; Fig. 3 is the stereogram of hobboing cutter; Fig. 4 is the stereogram of processed worm screw; Fig. 5,6 is the stereogram of hobboing cutter during from the both direction machining worm.
Number in the figure: 1 hobboing cutter, 2 main cutting edges, 3 front cutting edges, 4 first feeding cutting edges, 5 second feeding cutting edges, 6 worm screws, 7 chip pockets.
Below pass through the specific embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
The specific embodiment:
Embodiment: in conjunction with Fig. 1-3, the two-way feed worm hob of the present embodiment, hobboing cutter 1 integral body is annular (roughly being the solid tyre shape), and hobboing cutter is fixed on rotating shaft by its centre bore, rotates the machining worm screw.Along the circumferential direction interval etc. is arranged with a plurality of outstanding main cutting edges 2 and front cutting edge 3 on the periphery of hobboing cutter, and a plurality of main cutting edges 2 along the circumferential direction round on the periphery of hobboing cutter, and is interval etc. and minute distributes; A plurality of front cutting edges 3 are distribution side by side with a plurality of main cutting edges (2) on the axis direction of hobboing cutter.Form chip pocket 7 between adjacent two main cutting edges and adjacent two front cutting edges, hold iron filings when the cutting worm screw.
Shown in Fig. 3,5,6, in order to realize the two-way feed of hobboing cutter, from the axis direction of hobboing cutter, a circle is provided with the first feeding cutting edge 4 in the outside of main cutting edge 2, and the outside of front cutting edge 3 is provided with the second feeding cutting edge 5.
Shown in Figure 5, when machining worm 6, from the right side to the left during feeding, what worm screw was cut successively is the first feeding cutting edge 4, main cutting edge 2 when hobboing cutter, and this moment, the main cutting edge wearing and tearing were larger, and front cutting edge 3 is that processing is repaired by tooth section, weares and teares less.Shown in Figure 6, when hobboing cutter backward rotation feed reversing, be at first that the second feeding cutting edge is processed cutting to worm screw, this moment front cutting edge and main cutting edge effect and just now formed transposition.Be the effect that front cutting edge has played main cutting edge, wear and tear larger.Make major and minor cutting edge replace the main cutting effect, two-way feed, alternately wearing and tearing.This two-way feed formula worm hob makes worm hob can access sufficient utilization, the large reduction of manufacturing cost, and the processing number of packages of worm hob obtains increase at double, and utilization rate, the life-span of worm hob all are able to increase at double simultaneously.
