Description
Technical Field
The utility model relates to a round bending machine, in particular to an auxiliary rolling bending mechanism of a horizontal numerical control round bending machine.
Background
At present, a vertical type rounding machine or a horizontal type rounding machine is selected according to the processing requirements of different workpieces, such as the weight of the workpieces, the shape required to be formed and the like. The conventional horizontal type rounding machine comprises three working rolls, wherein two working rolls are utilized to form a supporting surface, and then the rest one working roll is utilized to apply pressure to the supporting surface, so that the profile is bent, but when the working rolls apply pressure to the supporting surface, the working rolls vibrate in the moving process, the three working rolls self-rotate, but the two working rolls forming the supporting surface do not limit the profile, so that the profile on two sides is bent due to vibration, deflection and other factors while rounding, and machining errors are caused. Because the traditional horizontal rounding machine only has three working rolls, different processing requirements are difficult to meet, and the work is single.
The bending machine is a machine capable of bending thin plates or tubular profiles and comprises a support, a workbench, a numerical control system and a hydraulic pump, wherein the workbench is arranged on the support, a cylindrical pressing die and a cylindrical pressure bearing die are arranged on the workbench, a through hole is formed in the workbench, and a piston rod capable of moving back and forth is arranged on the hydraulic pump. When the hydraulic press is used, the hydraulic pump pushes the pressing die to move forwards to cause pressure on the profile after being electrified, so that the profile is bent. The existing rounding machine has the defect that pressing dies with different sizes and specifications are required to be adopted when profiles with different shapes are processed, so that the pressing dies are required to be replaced frequently, and the production efficiency is reduced. Since the roll bending forming process is a process in which the material is elastically deformed, the rebound of the part is an unavoidable phenomenon, which is mainly represented by restoration of the bending angle and the radius of curvature of the part after the forming. The spring back phenomenon can affect the final shape and dimensional accuracy of the part, resulting in a part that does not meet the accuracy requirements.
