Description

Technical Field

[0001] The utility model relates to the technical field of spinning, in particular to a tube spinning fixture tooling. Background Technique

[0002] Spinning is to fix a flat or hollow blank on the mold of a spinning machine. While the blank rotates with the main shaft of the machine tool, a spinning wheel or a driving bar is used to apply pressure to the blank, causing local plastic deformation. Spinning is a special forming method. Various processes such as deep drawing, flanging, necking, bulging, and curling of rotating bodies of various shapes can be completed by spinning methods.

[0003] For example, the publication number CN218534098U discloses a tube spinning fixture tooling, belonging to the technical field of spinning. The tube spinning fixture tooling includes a mounting base; a mounting plate fixedly connected to the upper end of the mounting base; a mounting rod rotatably connected to one end of the mounting plate; a connecting plate fixedly connected to the circumferential surface of the mounting rod. When it is necessary to clamp and fix a workpiece, the workpiece can be placed on the circumferential surface of the mounting rod, and then the electric telescopic rod is started to make it extend and retract, thereby pushing the connecting ring to move. At this time, the clamping mechanism will be activated and the workpiece will be clamped, thus improving the stability of the workpiece placed on the circumferential surface of the mounting rod and preventing insufficient grinding of the workpiece due to insufficient fixation during the processing.

[0004] During the use of this device, only a single-sided electric push rod is used to drive the clamping jaws to fix it. This fixing method will cause a pressure difference between the upper and lower clamping forces of the clamped workpiece, resulting in insecure clamping. Therefore, a tube spinning fixture tooling is proposed to solve the above problems. Content of the Utility Model
