8 cooperations, described carbide blade 11 working rake angle is γ, γ=24 °, and roller finder 2 is installed in the side of described drive link 4, imitates
Shape roller 2 is located at the sidepiece of lathe tool 1, and the sidepiece of described drive link 4 installs slide key 5, the slip that moveable combination of guide rod 6 side wall opens up
Groove 13, the sliding tray 13 that slide key 5 and moveable combination of guide rod 6 side wall open up coordinates, described carbide blade 11 working orthogonal clearance α, α
The span of angle is 7～9 °.
Tool rest 7 of the present utility model is fixed on lathe carriage, and lathe tool 1 utilizes bolt presses in moveable combination of guide rod 6, lives
Equipped with the roller finder 2 contacting with surface of the work on dynamic guide rod 6, the spring 8 being arranged on knife rest afterbody occurs to stretch immediately, sliding
Dynamic key 5 makees corresponding slip therewith, and lathe tool 1 does contour turning campaign, thus completing whole body turning, roller finder 2 can achieve
Profiling, working special-shaped workpiece.Due to elongated thin-walled glass steel pipe（Band core）Integrated artistic system rigidity is poor, radiating condition
Difference, in profiling, easily tool marks and ripple in finished surface, and during this utility model turning, carbide blade 11 adopts γ
=24 ° of big working rake angle adopts working orthogonal clearance α simultaneously, and the span of α angle is 7～9 °, in conjunction with spring 8 and roller finder
The profiling effect of 2 generations, so can substantially reduce heat in metal cutting, the economiclife of lathe tool 1 can extend 10%-12%, simultaneously
The vibration producing in turnery processing can be reduced, it is to avoid tool marks and ripple easily in finished surface, due to elongated thin-walled glass steel pipe
（Band core）Integrated artistic system rigidity is poor, and radiating condition is poor, for such as nonmetallic glass-reinforced plastic material fragile material, work
Anterior angle γ directly affects sharpness and the cutting edge strength of lathe tool main cutting edge.Working rake angle γ increases, and the angle of shear is with increase, edge
The frictional force of rake face reduces, and therefore cutting force reduces, and heat in metal cutting also reduces.Facts have proved the work from conventional γ=0 °～20 °
Make anterior angle, find tube surfaces in addition to its colour changed into yellow color, also local aliquation and phenomenon of rupture.And working rake angle γ is increased to
When 24 °, tube surfaces no longer turn to be yellow, and phenomenon of rupture also.By the equal processing tasks of workload, the economy of lathe tool 1 makes
Use life longer 10%-12%.When working rake angle continues to increase to more than 24 ° by 24 °, experiment is successively read 25 ° to 29 °

Installation bolt 9 on described tool rest 7, bolt 9 and the cooperation of tool rest 7 screw thread, the screw mandrel end of bolt 9 is connected with spring 8.
Bolt 9 of the present utility model can adjust the compression degree of spring 8 thus adjusting profiling effect by rotation.
The sidepiece of described drive link 4 installs slide key 5, and the sliding tray that slide key 5 and moveable combination of guide rod 6 side wall open up is joined
Close, the sliding tray that the slide key 5 of utility model and moveable combination of guide rod 6 side wall open up coordinates drive link 4 can be avoided to rotate.
Described lathe tool 1 tool cutting edge angle κ r, r=75 ° of κ.Because the course of processing incision need to carry out turning, tool cutting edge angle κ in the middle of body
R adopts 75 ° of angles, reduces the load in unit sword length, improves cutting wear.When tool cutting edge angle κ r is set to 75 °, with workpiece and
The probability that imitation shape piece interferes is minimum, it is therefore preferable that tool cutting edge angle κ r is set to 75 °.
Described lathe tool 1 working orthogonal clearance α, the span of α angle is 7～9 °.Elongated thin-walled glass steel pipe is mainly by glass
Glass fiber wound and solidified molding, quality is harder, crisp.Little working orthogonal clearance α during turning, the span of α angle is 7～9 °
When can increase after knife face and fiberglass body contact area, the vibration producing in turnery processing can be reduced, it is to avoid processing table
Easily tool marks and ripple in face.
Phenomenon during working orthogonal clearance change in working angles
| Relief angle α | 7 °～8 ° | 8 °～9 ° | 10 °～14 ° |
| Heavy wall body | Cutting continuously sense without friction | Cutting continuously sense without friction | Cutting is continuous, sense without friction, non-ripple |
| Thin-walled body | The no obvious vibratory sensation of course of processing middle tube body, non-ripple | The no obvious vibratory sensation of course of processing middle tube body, non-ripple | Course of processing middle tube body has slight vibratory sensation, no obvious ripple |
In terms of observation situation from upper table, working orthogonal clearance α all reaches 10 ° and during with upper angle, to heavy wall body, does not find
Oscillation phenomenon, but to thin-walled body, due to process system poor rigidity, then create vibration, finished surface creates oscillation ripple,
Have a strong impact on surface quality and the performance of part.The oscillation phenomenon producing in turnery processing therefore to be eliminated, just need to reduce work
Relief angle, the contact area of knife face and fiberglass body after increase, it is to avoid oscillation mark easily in finished surface, and working orthogonal clearance takes 7
～9 ° more suitable.Find through quality testing, the body items Testing index processing is well.
Working cutting edge angle κ r is mainly and changes lathe tool 1 heat dispersal situations, and adapts to the rigidity of lathe one cutter one chucking appliance system
Need.It mainly affects the stability of tool strength, durability and process system processing.By the Wrapping formed pipe of reinforced plastic glass fibre
Body, elasticity is big, and poor rigidity is it is considered to the directivity of glass reinforced plastic winding layer and core act on, according to cutting force decomposition formula：Fy=
Fxycosκr；Fx=Fxysin κ r understands, working cutting edge angle κ r increases, and so that Fy is reduced, Fx increases, and this is conducive to mitigating workpiece
Deformation and the vibration of system.Cutting fine long thin-walled tube body fiberglass class workpiece, due to the course of processing need to cut in the middle of body into
Driving is cut, using κ r be 75 ° of tool cutting edge angles, reduce radial component Fy, reduce unit sword length on load, be reduce cutting temperature,
Improve important measures of cutting wear.Fact proved that equal processing conditionss can only cut 1 body in process of production
Cutter can be continuing with 1.5h.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.This practicality is new
The technology contents of the not detailed description of type are known technology.
