Abstract
The invention discloses a vertical stripping processing technology for manufacturing a seamless thin wall pipe, comprising the following steps: a. a machine tool with a perpendicular mold core column is prepared to be arranged; b. a thin wall plate is paved on the top of the mold core column; and c. through a perpendicular relative movement between a stripping roller and the mold core column, the thin wall plate is stripped. Three stripping rollers are provided, which are averagely distributed according to the circumference of the mold core column. In the process of stripping, the mold core column drives the thin wall plate continuously to turn; and the turning direction at every time is opposite to the rotation direction in the process of stripping at a former time. Cooling liquid is continuously splashed in the process of stripping. After the process of stripping, the manufactured thin wall pipe is processed by means of annealing and distressing. The mold core column is perpendicularly positioned instead of being transversely positioned previously; the thin wall plate is not needed to be processed into cap-shaped semi-finished products but directly into the desired thin wall pipe at one time; and the processing quality of the thin wall pipe can not be influenced by the function of the gravity.
Description
Technical field:
The present invention relates to a kind of stripping processing technology of producing seamless thin wall pipe.
Background technology:
Printer, the print quality of PRN device such as duplicator and facsimile machine depends on that to a great extent inner thin-walled tubing (comprises fixing roller, developer roll etc.) wall thickness influence, all require it to have heat conductivity and hear resistance efficiently to these thin-wall pipes, it is thin that this just requires that the thin-wall pipes wall thickness tries one's best, present processing technology all is earlier thin-wall boards to be carried out a deep draw processing, process cap shape semi-finished product, as shown in Figure 1, then these cap shape semi-finished product are placed on the mold core column of laterally putting, clamp the brim of a hat simultaneously, add motion back and forth about man-hour, the strip roller was done, mold core column drives the rotation that cap shape semi-finished product work does not stop simultaneously, and this processing industry process as shown in Figure 2.This technology is owing to be laterally to place adding the man-hour mold core column, and light-wall pipe is subjected to the influence of gravity to be easy to generate off-centre in the process of moulding, causes evenness of wall thickness, cylinder and flatness all poor, influences the print quality of PRN device.
Summary of the invention:
The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, a kind of vertical one-time formed stripping processing technology of producing seamless thin wall pipe is provided.
For achieving the above object, technical scheme provided by the invention is: a kind of vertical stripping processing technology of producing seamless thin wall pipe, and its processing step is as follows:
A. prepare to be equipped with the lathe of perpendicular mold core column;
B. spread a thin-wall boards at the top of mold core column;
C. do vertical relative motion by strip roller and mold core column, thin-wall boards is carried out strip processing.
Described strip roller is provided with three altogether, and they are evenly distributed by the mold core column circumference.
In the strip process, mold core column drives the rotation that thin-wall boards does not stop together, and each rotation direction with last time strip to add the direction of rotation in man-hour opposite.
Carry out the strip process not stop-spraying spill cooling fluid.
The rotating speed of mold core column is between 2300～2700rpm.
After finishing strip processing, the destressing of annealing is handled to the light-wall pipe of producing.
After adopting technique scheme, mold core column changes vertical placement into by original horizontal placement, need not reprocess out cap shape semi-finished product, but directly the thin-wall boards time processing be gone out required light-wall pipe, the process light-wall pipe can not be subjected to the effect of gravity, and influences crudy.
Description of drawings:
Fig. 1 is the structural representation of deep draw processing in the existing technology production process;
Fig. 2 is the process structure figure that existing technology is carried out the strip process;
Fig. 3 is a machining process schematic diagram of the present invention.
The specific embodiment:
Now 3 elaborate the present invention in conjunction with the accompanying drawings:
The vertical stripping processing technology of this production seamless thin wall pipe, its processing step is as follows:
A. mold core column is vertically mounted on the lathe, the controlled molding core of this lathe stem stem is done clockwise or counterclockwise autobiography motion, and the control mold core column axially moves back and forth;
B. spread the thin-wall boards that a wall thickness is 0.5mm, the sprinkling position of adjusting cooling fluid at the top of mold core column;
C., three strip rollers evenly are set near the top circumference limit of thin-wall boards, and the gap between adjusting strip roller and the mold core column is to the wall thickness thickness of required light-wall pipe;
D. start the strip roller, make the strip roller do the autobiography motion, do vertical relative motion with mold core column simultaneously, thin-wall boards is done strip processing along mold core column, add man-hour, mold core column is made the autobiography of rotating speed between 2300～2700rpm, constantly cools off to strip roller and thin-wall boards contact position sprinkling cooling fluid.
In the strip process, mold core column drives the rotation that thin-wall boards does not stop together, and each rotation direction with last time strip to add the direction of rotation in man-hour opposite, can effectively offset the internal stress that strip adds material internal generation in man-hour like this.After finishing strip processing, the destressing of annealing is handled to the light-wall pipe of producing.
By this new technology, can cancel and stamp out the half-finished step of cap shape in the prior art, save pressing equipment, strip process light-wall pipe can not be subjected to the influence of gravity again, the light-wall pipe thickness that processes is very even, cylinder and flatness are all very good, and can process thickness easily at the thick ultra-thin light-wall pipe of 0.03mm～0.09mm, greatly improve the print quality of PRN device.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
