Description
Technical Field
The invention relates to a rounding machine, in particular to a horizontal numerical control rounding machine.
Background
At present, according to the processing requirements of different workpieces, such as the weight of the workpiece, the shape required to be formed and the like, a vertical type rounding machine or a horizontal type rounding machine is selected. The traditional horizontal type rounding machine comprises three working rollers, wherein two working rollers are utilized to form a supporting surface, then the rest working roller is utilized to apply pressure to the supporting surface, so that the sectional material is bent, when the working rollers apply pressure to the supporting surface, the working rollers can vibrate in the movement process, the three working rollers can self-rotate, but the two working rollers forming the supporting surface do not limit the sectional material, so that the sectional materials at two sides are bent due to vibration, deviation and other factors while rounding is easily caused, and the machining error is caused. Because the traditional horizontal type rounding machine only has three working rolls, different processing requirements are difficult to meet, and the work is single.
The rounding machine is a machine capable of rounding a thin plate or a tubular section, 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 bearing die are arranged on the workbench, a through hole is formed in the workbench, and a piston rod moving back and forth is arranged on the hydraulic pump. When the device is used, the hydraulic pump pushes the pressure application die to move forwards to generate pressure on the section bar after being electrified, so that the section bar is bent and rounded. The existing rounding machine has the defect that when the sectional materials with different shapes are processed, pressing dies with different sizes and specifications are required to be adopted, so that the pressing dies are required to be frequently replaced, and the production efficiency is reduced. Since the roll bending forming process is a process of elastic-plastic deformation of a material, the rebound of a part is an inevitable phenomenon, and the rebound phenomenon is mainly represented by the recovery of a bending angle and a curvature radius of the part after the part is formed. The spring back phenomenon affects the final shape and dimensional accuracy of the part, resulting in the part not meeting the accuracy requirements.
The domestic roll bending forming process is researched late, the same competitive products cannot reach the level of foreign products, and foreign high-end section bar roll bending equipment is introduced into domestic and multi-family civil engineering enterprises for production successively in recent years. However, as the core technology of the control system is still mastered in foreign enterprises, many aircraft roll bending parts can not be produced independently so far and need to be imported, and the control system is restricted by people and seriously influences the development progress of new products.
