Description
Technical field
The utility model is related to a kind of processing utensil, more particularly to it is a kind of be applied to the industry productions such as metallurgy, machinery without
Stitch the boring machine cutting tool of the ring pass machining of steel pipe.
Background technology
At present, seamless steel pipe is a kind of common metallurgical product, and uses cold-rolling deformation processing to be production seamless steel pipe
Major way, wherein, two roller periodic seamless steel pipe cold-rolling mills are to apply the most commonly used cold rolling life in cold-rolling deformation processing
Production equipment, the interval length of the specific rolling deformation of the cold-rolling mill, stability is good, without wedge stress the features such as, and matched nothing
The annular distance type cold-rolling deformation technology of steel pipe is stitched, is also widely used by the two rollers periodic seamless steel pipe cold-rolling mill.
The annular distance type processed of seamless steel pipe is used in pairs in cylinder, and core is machined with manhole, sets interference
Measure and by temperature differential method assembled orientation on the roll shaft of roll device.Process rectangular channel on one transverse plane of annular distance type, for
The positioning of roll device roll shaft, it is determined that the initial point position (entrance point for rolling groove) of rolling groove.The cylindrical weekly form of annular distance type
Face is machined with the cone constituted after the groove (rolling groove) of section semicircular in shape, groove planar development in full curve, seamless
Steel pipe is exactly to have big to realizing that metal cold deformation adds after small be extruded in the closed groove constituted in upper and lower two pieces annular distance type
Work.Therefore the crudy of annular distance type, especially rolls the machining accuracy of groove, directly determines that seamless steel pipe cold-rolling deformation is processed
Quality and efficiency.
And the current cold rolling material with seamless steel pipe annular distance type is H13 (steel grade model), and need to forge steel billet, it is seamless
Steel pipe is by machining.Generally require by cutting (sawing), forging, turning (horizontal lathe processing excircles and plane), boring
(special boring mill roughing rolling Slot shaping is stayed for hole (lathe process endoporus), recessing (horizontal lathe processes isometrical rolling groove), boring
Surplus), planing (horizontal planer locating and machining groove), heat treatment (quenching), (surface grinding machine is processed plane, cylindrical grinder and added for grinding
Work is cylindrical, internal grinder processing endoporus etc.), slot boring (special boring mill precision processing rolling groove), examine, storage (upper grease, bag
Dress) etc. process.
Wherein, one of critical process of ring pass machining Boring machine processing rolling groove process, be exactly will through Overheating Treatment with
And the annular distance type after grinding machine finishing, it is placed in pairs in the lathe bed plane of boring machine on two relatively independent vertical rotating shafts solid
It is fixed (special positioner to be provided between annular distance type and rotary shaft, and determining of matching is selected according to different processing specifications
Position device), using machining tools (tool rest and blade unit), using the high speed rotary motion of cutter, to around the center of circle from
The ring groove rolling groove turned carries out precision machining, complies with technical requirements.By rolling groove is by full curve institute group
Into cone, therefore cutting tool for boring is in the presence of special pattern, along vertical direction displacement (reducing), realizes time processing
The function of not isometrical rolling groove.The process will directly determine the final product quality of annular distance type, once there is deviation, whole inner loop pass
It will scrap, or change a social system other specifications, therefore it is exactly the pass in whole annular distance type machining operation to roll the boring processing of groove
Key process.
So, in the manufacturing procedure of seamless steel pipe ring groove rolling groove, cutting tool for boring plays the effect of key.And it is existing
Cutter under technology is made up of fixed tool rest and ceramic tip, and the fixed tool rest is in the stepped cylindrical body in different footpaths with one heart
Four circular holes are machined with structure, the big footpath cylinder in bottom, for tool rest to be integrally attached into boring machine water using soket head cap screw
Square to cutting spindle end face, fixed tool rest front end is shaft portion, has big to small transition, has in the front end of shaft portion
Screw tightening member, by the clamping action for screwing generation of screw, the ceramic tip for fixing rectangular configuration.Pass through level
The cutting spindle high-speed motion in direction, so as to drive cutter at high speeds to rotate, by the ceramic tip of cutter foremost, to through overheat
The rolling groove of processing quenching carries out precision machining.
Due to enterprise development and the change of the market demand, the specification of seamless steel pipe production is more and more, especially greatly
The product of specification progressively turns into the main product of enterprise, therefore annular distance type processing capacity corresponding to larger product progressively increases,
And the boring machine cutter under prior art can only meet export processing end internal diameter (production tube external diameter)Rolling groove
It is required that, and the rolling groove more than 42mm can not just be processed due to the radius of machining reason of cutter, can only be used other processing sides
Formula, result in processing, time-consuming, uncontrolled, costly.
In order to solve this problem, prior art is to employ the method for customizing big specification boring machine cutting tool, and being exactly will
The tool rest front end shaft portion diameter increase of cutter, meets the requirement that the big specifications of more than 42mm roll groove, but due to processing every time
Rolling groove specification it is different, it is therefore desirable to frequent dismounting and change cutter, subsidiary operation time is so both added, while often tearing open
Fill and the screwed hole of horizontal direction cutting spindle and positioning hole etc. also adversely affected, in addition, the cutter procurement price customized compared with
Height, virtually also increases production cost.
Utility model content
The problem of in order to solve to exist under prior art, the utility model provides one kind and added for seamless steel pipe annular distance type
The boring machine cutting tool of work, by being changed accordingly with ring groove rolling groove cutting tool for boring to existing seamless steel pipe is cold rolling
Enter, applicability of the increase cutting tool for boring when processing different size rolling groove can meet the need of ring groove rolling groove cutting processing
Ask, and production cost can be reduced, be easy to routine maintenance work.
