Embodiment 1

[0038] like Figure 1 to Figure 3 As shown, the profile forward and reverse bending mechanism of the present invention includes a first forming wheel assembly 1, a second forming wheel assembly 2 and a forming wheel distance driving assembly, wherein the first forming wheel assembly 1 is provided with a first forming wheel 1.1, a second forming wheel The wheel assembly 2 is provided with a second forming wheel 2.1. The diameters of the first forming wheel 1.1 and the second forming wheel 2.1 are different, and the first forming wheel 1.1 can make a circular motion with the center of the second forming wheel 2.1 as the center of the circle. The forming wheel 2.1 can move in a circle with the center of the first forming wheel 1.1 as the center of the circle. The distance between the first forming wheel assembly 1 and the second forming wheel assembly 2 is adjusted by the forming wheel distance driving assembly. The position between the first forming wheel 1.1 and the second form...

Embodiment 2

[0051] The difference between this embodiment and the first embodiment is only that: the forward and reverse bending method of the profile of the present invention comprises the following steps:

[0052] Step 1: Move the first forming wheel assembly to the center of the rotating base, control the first forming wheel assembly and the second forming wheel assembly to rotate synchronously on the circular plane to adjust the rotation angle of the second forming wheel assembly, and control the profile bending process. Push the position to realize the positive bending of the profile;

[0053] Step 2, move the first forming wheel assembly away from the center of the rotating base, move the second forming wheel assembly to the center of the rotating base, and control the first forming wheel assembly and the second forming wheel assembly to rotate synchronously in the opposite direction on the circular plane to adjust The rotation angle of the first forming wheel assembly controls the ...

Abstract

The invention provides a forward and reverse bending mechanism and a bending method thereof. The forward and reverse bending mechanism includes a first forming wheel assembly, a second forming wheel assembly and a forming wheel distance driving assembly; the first forming wheel assembly is provided with a first forming wheel , the second forming wheel assembly is provided with a second forming wheel; the first forming wheel can perform circular motion with the center of the second forming wheel as the center of circle, and the second forming wheel can perform circular motion with the center of the first forming wheel as the center of circle; The distance between the first forming wheel assembly and the second forming wheel assembly is adjusted through the forming wheel distance drive assembly; the position between the first forming wheel and the second forming wheel is used as a profile bending station; during work, By controlling and adjusting the relative positions of the first forming wheel assembly and the second forming wheel assembly, the forward and reverse bending of the variable curvature of the profile is realized. The invention can realize forward bending and reverse bending with variable curvature of the profile, thereby improving the bending efficiency of the profile and the quality of the profile bending process.

Description

technical field [0001] The invention relates to the technical field of profile processing, and more particularly, to a forward and reverse bending mechanism for a profile and a bending method thereof. Background technique [0002] Bending profiles are widely used in automotive, aerospace, pipeline engineering, construction machinery, petrochemical and other industrial fields, occupying a very important position. With the continuous development of science and technology, curved profiles are widely used in various industries, and the quality of curved profiles will directly affect the safety, reliability and rationality of product structures in these industries. [0003] Most of the existing bending mechanisms on the market are based on the principle of three points forming a circle, and use the relative position change and rotational movement of the work rolls to produce continuous plastic deformation of the profile to obtain a profile workpiece of a predetermined shape. If ...
