Description
Technical field
The present invention relates to tubing bending field, particularly relate to a kind of process for tubing bending.
Background technology
Tubing bending is the requirement that mechanical field usually needs to relate to, existing tubing bending mainly comprises CNC Digit Control Machine Tool manufacture method and stamping manufacture method, wherein CNC Digit Control Machine Tool manufacture method is the shape polishing tubing bending on the tubing basis much larger than bending tubing, the method causes tubing and wastes greatly, inefficiency, stamping manufacture method chooses the diameter that transverse cross-sectional diameter is greater than required tubing to carry out punching press bending, again the damaged part of bending is polished, complex procedures, inefficiency, therefore existing brake techniques is all unfavorable on a large scale, the tubing bending of high request manufactures.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of process for tubing bending, grasping tubing by adopting with the gripper that pipe geometry fits, adopting rotating direction and tubing to push the identical roller in direction to carry out bending tubing, both with the use of, screen resilience when fully absorbing tubing bending, substantially reduce the mechanical damage of bending part, improve the smoothness of bending part, operation simplifies, efficiency improves, economical and practical, the process for tubing bending universal on have market prospects widely.
For solving the problems of the technologies described above, the invention provides a kind of process for tubing bending, comprising the following steps:
(1) tubing is chosen: selection cross section is circle, the uniformity is good, diameter range is that the tubing of 0.1-20mm is as tubing to be produced;
(2) hole: use the first drill bit in the boring of the front end of the tubing chosen, use the second drill bit to hole at the tail end of tubing;
(3) bending: use gripper to grasp tubing and treat that the inner side of bending part pushes forward, use roller to treat that the outside of bending part applies certain pressure and makes it bend at tubing simultaneously, the top of described gripper is provided with groove, described groove and described tubing fit, described roller and described gripper are located along the same line move toward one another, the rotating direction of described roller is identical with the propelling movement direction of described tubing, screen resilience when absorbing tubing bending by the motion of roller, thus reduce mechanical damage, improve the smoothness on surface;
(4) polishing: carry out polishing, grinding to tubing, makes its smooth surface.
In a preferred embodiment of the present invention, the diameter of the lateral cross section of described tubing is 2mm.
In a preferred embodiment of the present invention, the surface of described first drill bit is provided with screw thread.
In a preferred embodiment of the present invention, the diameter of the lateral cross section of described first drill bit and described second drill bit is all less than the diameter of the lateral cross section of described tubing.
In a preferred embodiment of the present invention, the cross section of described groove is circular arc.
The invention has the beneficial effects as follows: the present invention is used for the process of tubing bending and has that operation simplifies, reduces damage, smooth surface, raises the efficiency, the advantage such as economical and practical, has market prospects widely popularizing of the process for tubing bending.
