Embodiment 1

[0028] Such as figure 1 as shown, figure 1 It is a flow chart of Embodiment 1 of the present invention. Embodiment 1 of the present invention provides a method for controlling bending of a pipe bender after strong force, and the steps of the method are as follows:

[0029] S1: Read the angle of the elbow, clamp the mold, and push the auxiliary clamp;

[0030] The bending angle C, bending radius R and wheel mold radius are read by the pipe bending machine control system, and the pipe fittings are clamped by the clamping die and the auxiliary push shaft after loading;

[0031] S2: Calculate the feeding length and auxiliary feeding length;

[0032] According to the elbow bending radius R and bending angle C technical parameters read by S1, the feeding feed length Y and auxiliary feed length F are calculated; the calculation method is as follows:

[0033] Known: bending radius R, bending angle C, coefficient K ranges from 0.8 to 1.2;

[0034] Suppose: the feeding length is Y, ...

Embodiment 2

[0047] Such as figure 2 As shown, Embodiment 2 of the present invention also proposes a post-bend boost control system. The control system uses the powerful post-bend tube bend control method of the above-mentioned Embodiment 1 to achieve 1.5D small bending To meet the production requirements of curved pipes with a radius, the control system includes feeding shaft 1, auxiliary pushing shaft 2, wheel mold 3 and clamping die 4. One end of the pipe fitting 5 is clamped by the feeding shaft 1, and the other end is clamped by the clamping die 4. The auxiliary pushing shaft The shaft 2 is arranged outside the middle part of the pipe fitting 5, and the auxiliary pushing shaft 2 is close to the pipe fitting 5, and the figure 2 The direction of the arrow in the figure is the direction of the bent pipe, which is only for illustration and does not limit the present invention.

[0048] Through the implementation of Embodiment 2 and Embodiment 1, compared with the traditional bending mo...

Abstract

The invention discloses a strong rear propelling tube bending control method of a tube bending machine and a system, and belongs to the technical field of bent tube production control. The method comprises the steps that: S1: a tube bending angle is read, and a clamp die and an auxiliary pusher clamp materials; S2: the feeding lengths of a material supplying device and the auxiliary pusher are calculated; S3: synchronous feeding of a tube bending shaft, the material supplying device and the auxiliary pusher is carried out and output torque control over a material supplying shaft is conducted;S4: tube bending ceases, and the clamp die and the auxiliary pusher are loosened; and S5: a rotating mechanism rotates by a processing angle to conduct next tube bending processing, and step S2 is resumed. The system comprises the material supplying shaft, an auxiliary pushing shaft, a wheel mold, and the clamp die; a tube is clamped by the material supplying shaft and the clamp die; and the auxiliary pushing shaft is closely against the tube. According to the method and the system, the technical requirement that a tube is bent by a small bending radius of less than 1.5D can be met; differentdata are input for different radiuses, and then the system can automatically calculate a propelling route and a propelling torque; requirements of vehicle exhaust pipes, air conditioning pipes and special aeronautic tubes can be met; and the mechanical structure is simple, technical modification can be conveniently performed by equipment manufacturers and the universality is high.
