Abstract
The invention relates to a combined turning rolling device used for processing a taper hole, wherein, two mechanically processing procedures are combined reasonably, so that the turning technology and the rolling technology can be achieved in the processing procedures during one cutting feed process, the matching quality can be improved, and processing cost is lowered; in addition, the surface roughness of an inner wall of the taper hole can be reduced to one to two stages by adopting the rolling technology, and the rigidity and the fatigue strength of an inner surface of the taper hole can be improved.
Description
Technical field
The present invention relates to a kind of turning roll extrusion composite set of processing taper hole, belong to taper hole process tool technical field.
Background technology
Technical disadvantages such as surface roughness is too high, dimensional uniformity difference appear in taper hole that present taper hole process technology is processed easily.In order to reduce the surface roughness of taper hole, subsequent technique often adopts grinding machine that taper hole is carried out grinding, increases this technology and not only prolongs the duration but also increased production cost.
Chinese patent CN201632807U discloses a kind of taper hole rolling tools, is characterized in that the milled head conical surface is provided with roller, and the conical surface of the rolling surface protrusion milled head of roller carries out roll extrusion through rolling surface extruding taper hole inwall, improves the fineness of taper hole inwall.The deficiency of this patent is obvious: only have single roll extrusion function, and do not possess this technical characterictic of turning function.This shows that will seek out desirable conical surface effect need increase one procedure, does not obviously meet the production standard of efficient energy-saving.
Summary of the invention
In order to solve above technical problem, the present invention discloses a kind of turning roll extrusion composite set that is specifically designed to the processing taper hole, and it not only can realize the turning to taper hole, and can carry out roll extrusion to the taper hole after the turning simultaneously.
Technical program of the present invention lies in:
A kind of turning roll extrusion composite set of processing taper hole; Comprise knife bar, carbide cutter tool and support set, the front end of described knife bar is set with bolt, and support set is enclosed within on the bolt and is fixedly connected with knife bar through nut; It is characterized in that; First half at support set raises tool bore and downward modulation tool bore to running through to be provided with crosswise, and the bottom of downward modulation tool bore tilts to the direction away from knife bar, raises tool bore and downward modulation tool bore co-axially align; Described carbide cutter tool runs through to be arranged on and raises in tool bore, the downward modulation tool bore, and the carbide cutter tool shank is fixed by micrometer adjusting screw, and described micrometer adjusting screw is threaded with raising tool bore, in reducing tool bore, is provided with hold-down bolt; Align and between support set and knife bar, be set with pressure roller with the downward modulation tool bore, the outer rim of said pressure roller and the vertical range between the cutter spindle are greater than the point of a knife of carbide cutter tool and the vertical range between the cutter spindle.
Angular range between the axis of said rise tool bore, downward modulation tool bore and the longitudinal axis of support set is 100 °-110 °.
The end that said support set and knife bar are relative is provided with boss.The purpose that boss is set is, fixedly pressure roller.
Characteristics of the present invention:
First half at support set raises tool bore and downward modulation tool bore to running through to be provided with crosswise; Making the setting of carbide cutter tool no longer is vertical each other with the axis of support set; The accurate preset press polish of outside micrometer easy to use allowance provides corresponding techniques to guarantee for accurately processing taper hole; Wherein the carbide cutter tool shank is fixed by micrometer adjusting screw; Described micrometer adjusting screw is threaded with the rise tool bore; Can be through the convenient position of regulating point of a knife of micrometer adjusting screw; Not only reduce the frequency of changing carbide cutter tool, prolong the service life of alloy knife, and can also adapt to the taper hole of processing different angles; Align and between support set and knife bar, be set with pressure roller with the downward modulation tool bore; The advantage of this technical characterictic is; With twice machining operation reasonable combination, make its one-pass in manufacturing procedure just can accomplish turning and two kinds of technologies of roll extrusion, improve fit quality; Not only practice thrift processing cost, and the taper hole dimensional uniformity that processes is good.
Compared with prior art, excellent results of the present invention is:
1, with twice machining operation reasonable combination, make its one-pass in manufacturing procedure just can accomplish turning and two kinds of technologies of roll extrusion, improve fit quality, not only practice thrift processing cost, and the taper hole dimensional uniformity that processes is good;
2, adopt roll extrusion, the surface roughness one that reduces the taper hole inwall is to two-stage; Utilize the cold plasticity characteristics of metal, the inner surface of taper hole is applied certain pressure, make the endosexine metal produce plastic flowing, be filled in the original residual indentation trough, reduce and reach the surface of the work roughness value through pressure roller at the normal temperature state.
3, improve the hardness of taper hole inner surface, stress deformation is eliminated, hardness improves HV >=4 °, improves fatigue strength 30%;
