Sheet material bending and stamping integrated forming method

Abstract

The invention belongs to the technical field of sheet material machining, and particularly relates to a sheet material bending and stamping integrated forming method. The sheet material bending and stamping integrated forming method comprises the following steps that a controller is used for automatically adjusting the bending angles of a variable upper tool array and a variable lower tool array to the needed bending angles; a sheet material is taken, a bending line is drawn, and the sheet material is put under the variable lower tool array; the controller is used for controlling the variableupper tool array to be aligned with the bending line of the sheet material downwards in the vertical direction and compress the sheet material; the controller is used for controlling the variable upper tool array to freely bend the sheet material, and when the sheet material and a tool edge of the variable lower tool array are attached, the variable upper tool array corrects and bends the sheet material to form a bent part; and the controller controls a pressing module to ascend, a lifting module drives the variable upper tool array to automatically reset, the controller controls the variablelower tool array to automatically expand the tool edge, and the bent part is jacked out and taken down. The bending angle of the sheet material is accurate by automatically adjusting the bending angleof the sheet material, and the forming yield of the bent part is improved.

[0002] The essence of the CNC bending machine is a CNC bending machine mold for bending thin plates. The CNC system controls the up and down movement of the hydraulic cylinder, thereby driving the mold installed on the slider to move up and down, and the lower mold installed on the workbench Extrusion is generated to realize the bending of the workpiece. In the process of bending the workpiece, the bending angle is often uncontrollable, and the accuracy of the angle of the bending piece cannot be achieved. After bending, many parts need to be corrected before they can be bent. In the final forming, there are many plates that are not easy to manually beat for bending correction due to their thicker materials. They need to be baked to bend the bent parts to the required angle, which is time-consuming and labor-intensive, especially for new product trial production. Parts suppliers have higher requirements. The dimensional inspection of each new product must be within the specified error range. If the error exceeds the error, it will be unqualified. If the trial production of new product parts fails, the new product will be sent back for redo, or the OEM Orders to parts suppliers will be canceled

[0003] In the new product trial production workshop, there are many kinds of products and heavy tasks. The products that often need to be processed are not produced before. When bending the plate, the product needs to be adjusted to various angles, and the required bending is performed manually. It is troublesome, time-consuming, labor-intensive, and inefficient, which seriously affects the completion of production tasks. At the same time, some products are not only The bending process needs to be carried out, and stamping is also required. Therefore, changing the machine tool for stamping after bending the plate or changing the machine tool for bending after stamping the plate will affect the efficiency of plate processing and forming
