Abstract
The invention relates to a turning method of an excircle of a hollow metal tube, which comprises the following steps: filling filler in the metal hollow pipe, and sealing two ends of the metal hollow pipe by using plugs; two ends of the hollow metal pipe are mounted on a lathe through a tip, and one end of the hollow metal pipe is fixed on a lathe chuck through a chuck, so that the hollow metal pipe rotates along with the lathe chuck; the metal hollow pipe body is limited by the follower rest. The method is simple and easy to implement, low in cost, obvious in shockproof effect and capable of ensuring the processing quality.
Description
Technical field
The invention belongs to field of machining, and in particular to a kind of turning processing method of metal hollow pipe outer circle.
Background technique
Stainless hardness of steel is high, plasticity is good, and processing hardening is serious when cutting, and resistance to cutting is big, and cutting temperature is high, leads to cutter
Serious wear, easy damaged workpiece machined surface, influences part quality, and productivity is extremely low.
Under the action of cutting force (particularly radial cutting force), it is easy to produce vibration and deformation, influences the size of workpiece
Precision, shape, position precision and surface roughness.
The rigidity of thin-wall part is poor, can often generate vibration in turning process, and when turning stainless steel elongated tubular is especially tight
Weight, causes workpiece surface roughness numerical value to become larger, and reduce tool life.It is easy because of deformation when turning thin-wall workpiece
Cause to vibrate, and the deformation of workpiece will be aggravated by vibrating, the two is interrelated.
Summary of the invention
The object of the present invention is to provide a kind of turning processing methods of metal hollow pipe outer circle, comprising the following steps:
Filler is filled up in metal hollow pipe, and is closed at the both ends of metal hollow pipe with plug；The metal hollow
The both ends of pipe are installed on lathe by top, and metal hollow pipe is fixedly installed on lathe chuck by a heart carrier, is made
Metal hollow pipe is obtained to rotate with lathe chuck；Metal hollow pipe pipe shaft is limited by follow-rest.
Further, the filler is sawdust or plastic pellet.
Further, the plug is bakelite.
Further, there is braided fabric interlayer between the plug and metal hollow pipe.
Further, the braided fabric is cloth.
Further, the bearing claw of follow-rest and the material of plug are identical.
Further, the radian of bearing claw is corrected, so that bearing claw is bonded with the outer circle of metal hollow pipe.
Further, the collet is heart carrier.
The beneficial effect of present system is that this method is simple and easy, and low in cost, shockproof effect is obvious, processing quality
It is guaranteed.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is metal hollow pipe clamping schematic diagram of the present invention.
Fig. 2 is the A-A diagrammatic cross-section of Fig. 1.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
Referring to Fig. 1,2, a kind of turning processing method of metal hollow pipe outer circle includes the following steps: in metal hollow pipe 3
Filler 4 is filled up, when Vehicle Processing rotates, under the influence of centrifugal force, filler 4 can provide one to 3 tube wall of metal hollow pipe
Power radially, can partial offset Vehicle Processing cutting force, improve machinability；At the both ends of metal hollow pipe 3 by upper stifled
First 2, the both ends of metal hollow pipe 3 are axially fixed on lathe by first, second top 1,5, are provided more for clamping
Supporting point further improves machinability to improve the rigidity of metal hollow pipe 3；Metal hollow pipe 3 is solid by heart carrier
Dingan County is loaded on lathe chuck, so that metal hollow pipe 3 is rotated with lathe chuck, follow-rest 6 resists the pipe shaft of metal hollow pipe 3
It realizes limit, increases supporting point, further increase rigidity, improve machinability.
The filler 4 be sawdust or plastic pellet, it is simple and convenient, it is low in cost.Filler may be other forms,
As long as can fill in metal hollow pipe 3.
Plug 2 is bakelite material, has braided fabric interlayer between plug 2 and metal hollow pipe 3, which is preferably
Cloth, easy to use, low in cost, effect is good.The braided fabric may be other forms, as long as frictional force can be improved.
Above-mentioned follow-rest 6 includes frame body, and frame body is frame shape, and adjustable bearing claw 7, the number of bearing claw 7 are equipped on frame body
Amount is two or more, is preferably three, symmetrical in aplysia punctata, completes supporting role with least quantity, frame body is annular
Framework.Bearing claw 7 is identical as 2 material of plug.And the radian of bearing claw 7 is corrected, so that the pipe of bearing claw 7 and metal hollow pipe 3
Body fitting, so that follow-rest 6 plays better stabilization to metal hollow pipe 3, cooperates above-mentioned processing method, processing quality is more
It is high.
This programme is particularly suitable for the turning processing method of coaxial metal hollow pipe 3, especially stainless steel coaxial metal pipe
Turning processing method.
The invention has the advantages that this method is simple and easy, low in cost, shockproof effect is obvious, and processing quality has guarantor
Card.
