CNC sheet profiling spinning machine

Abstract

The invention discloses a numerically controlled thin plate profiling spinning machine, which comprises a frame, a main shaft equipped with a round die base, a thimble mechanism capable of clamping and positioning the metal sheet on the round die base, and a spinner for spinning the thin plate. Pressing mechanism, and the numerical control drive assembly that drives the movement of the above-mentioned spinning mechanism, the key point of its design is that the spinning mechanism includes a seat body and a slide plate mounted on the seat body that can slide back and forth, and the seat body is provided with a preload for pushing the slide plate outward. The spring is equipped with a roller assembly for spinning on the slide. The object of the present invention is to provide a numerically controlled sheet profiling spinning machine capable of adaptively adjusting the interaction force between the spinning mechanism and the sheet.

Description

[technical field] [0001] The invention relates to a numerically controlled sheet profiling spinning machine for forming thin metal sheets by spinning in the field of mechanical forming. [Background technique] [0002] Spinning forming is a processing method that uses a spinning mechanism to spin the metal sheet along the outer peripheral shape of the forming die. It can be applied to metal products with axisymmetric processing centers, such as kettles, pots, and bowls. Kitchen utensils such as bowls, electrical parts such as lampshades and loudspeaker parts, automobile parts such as wheels and wheel covers, and the processing of various jars, containers, covers and other products. [0003] The spinning mechanism of the existing spinning equipment generally uses numerical control to control the movement of the spinning mechanism to improve processing efficiency. However, the roller tool on the existing spinning mechanism directly presses the thin plate, so that the thin plat...

Problems solved by technology

Due to the error in the movement of the drive assembly driving the spinning mechanism through the program control of the external controller, the walking path of the roller cutter on the spinning mechanism is not unique, and the roller cutter is in rigid contact with the thin plate during spinning, and the thickness of each thin plate is different. , some thin plates are thicker, and some thin plates are relatively thin, so that when the roller cutter presses the thicker sheet, the force on the roller assembly is large, and vibration is prone to cause the surface of the pressed workpiece to be uneven. At the same time, the roller cutter is stressed and easily Damage deformation
