Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, and in particular to a horizontal double-wheel hot spinning and closing spinning machine. Background Technology

[0002] Spinning is a sheet metal forming process in which a flat or hollow blank is fixed on a die of a spinning machine and rotates with the spindle; simultaneously, pressure is applied to the blank through a spinning wheel or guide rod, causing localized plastic deformation. This process can form sheet metal parts with various complex geometric features and is a special sheet metal forming method. Spinning can be used to manufacture various complex geometric shapes such as deep drawing, flanging, necking, bulging, and curling. For example, patent document CN113385571A, entitled "A CNC Tube and Sheet Spinning Machine," discloses a CNC tube and sheet spinning machine. The machine uses a fixed clamp and an auxiliary hydraulic clamp to fix the workpiece. A motor drives the fixed clamp to rotate, causing the workpiece to rotate. A feeding mechanism and a hydraulic cylinder control the horizontal and vertical movement mechanisms to adjust the position of the spinning rollers. The spinning rollers then shape the workpiece by spinning. The machine frame adopts a symmetrical double-gantry structure, which is highly rigid. The symmetrical arrangement of the spinning rollers ensures that the lateral forces exerted on the workpiece by the spinning rollers during spinning are mutually canceled, protecting the bushing in the fixed clamp and extending its service life.

[0003] However, the above-mentioned technical solution suffers from insufficient spinning strength when spinning harder pipes. Therefore, it is necessary to develop a newer technical design that is compact in structure and can heat and soften the pipe before spinning to solve the above problems. Utility Model Content

At least two third receiving rollers 91 are provided, forming a "V" shaped groove between them. In this embodiment, after the push transmission assembly drives the push hook to push the workpiece out of the "V" shaped groove formed by the first receiving roller, the workpiece moves to the "V" shaped groove formed between the second receiving rollers and passes through the receiving hole, then moves to the "V" shaped groove formed between the third receiving rollers. Of course, this is not limited to this; other components that can achieve the same function can be used.

[0045] Working Principle: During operation, the workpiece is clamped by the clamping assembly. The heating horizontal movement assembly drives the heating conduit forward, and the heating height adjustment assembly drives the heating conduit up and down, allowing it to be fitted over the workpiece for heating. After heating, the heating horizontal movement assembly and the heating height adjustment assembly drive the heating conduit away from the workpiece. Then, the tail-end cylinder drives the ejector assembly to extend and retract within the tail-end seat, and the tail-end transmission assembly drives the tail-end seat to move, thus securing the ejector assembly to the workpiece. Subsequently, the power unit drives the spindle to rotate via the gear assembly. The transverse and longitudinal feed transmission assemblies achieve transverse and longitudinal feed machining of the spinning roller. Simultaneously, the heating compensation transmission motor drives the heating compensation transmission screw to rotate, which in turn moves the spray gun mounting block along the heating compensation transmission rail, allowing the heating compensation spray gun to adjust according to the heating requirements. The workpiece is moved to a suitable position, and a heat-compensating spray gun heats it to maintain a constant temperature required for processing. After the spinning wheel completes the processing, the transverse and longitudinal feed transmission components drive the spinning wheel to retract. The pusher motor drives the pusher screw to rotate, which in turn moves the pusher seat on the pusher slide rail. The pusher seat then moves the pusher rod within the mandrel, pushing the workpiece out of the fixture after processing. The receiving cylinder pushes the receiving base upwards, and the pusher rod pushes the workpiece into the "V" groove formed by the receiving roller one. Subsequently, the pusher transmission component drives the pusher hook to push the workpiece out of the "V" groove formed by the receiving roller one. After the pusher transmission component drives the pusher hook to push the workpiece out of the "V" groove formed by the receiving roller one, the workpiece moves to the "V" groove formed between the receiving roller two and passes through the receiving hole. Then, it moves to the "V" groove formed between the receiving roller three.
