Description

Technical Field

[0001] This utility model relates to the field of vertical spinning machine technology, and in particular to a vertical spinning machine with automatic demolding and clamping. Background Technology

[0002] Vertical spinning machines primarily utilize the relative motion between a rotating workpiece and a pressing tool to induce plastic deformation in metal materials under pressure, thereby achieving the desired shape and size. Spin forming is a plastic processing method that uses a spinning tool to apply pressure to a rotating blank, causing continuous localized plastic deformation to form the desired hollow rotating part. It is a commonly used process for manufacturing thin-walled rotating parts, capable of performing various forming processes such as deep drawing, flanging, and end closing. It offers advantages such as high product manufacturing precision and lightweight construction, and holds an important position in the fields of aerospace, military, and other precision metal machining technologies.

[0003] In existing vertical spinning machines with automatic demolding and clamping, the fixing device needs to be replaced when fixing molds of different sizes, which consumes a lot of time and greatly reduces the overall work efficiency, thus limiting its practicality. Therefore, we propose a vertical spinning machine with automatic demolding and clamping to solve this problem. Utility Model Content

Since the pressure plate is in contact with the workpiece and the mold, this rotation is also transmitted to the workpiece and the mold. At the same time, since the worktable is rotatable, when the pressure plate, workpiece, and mold rotate together, the worktable will also rotate, thereby ensuring that the workpiece obtains a uniform processing effect during the spinning process.

Two guide posts 26 are fixedly installed on the top of the U-shaped bracket 23. The top of each guide post 26 is fixedly installed on the bottom of the circular push block 25. The top of the U-shaped bracket 23 is fixedly installed with a hydraulic cylinder 24. The output end of the hydraulic cylinder 24 is fixedly connected to the bottom of the circular push block 25, so that by starting the hydraulic cylinder 24, the circular push block 25 can be moved vertically, which in turn moves the circular top plate 6 that is in contact with it vertically, thereby causing the circular top plate 6 to push out the workpiece processed in the mold 5, thus realizing rotational demolding.

[0024] In this embodiment, an L-shaped support plate 2 is fixedly installed on the top of the base 1. A second hydraulic cylinder 27 is fixedly installed on the inner side of the top of the L-shaped support plate 2. A connecting plate 28 is fixedly connected to the output end of the second hydraulic cylinder 27. Multiple second guide columns 34 are fixedly installed on the inner side of the top of the L-shaped support plate 2. The bottom of the multiple second guide columns 34 is fixedly installed on the top of the connecting plate 28. A second motor 29 is fixedly installed on the bottom of the connecting plate 28. A rotating shaft 30 is fixedly connected to the output end of the second motor 29.

[0025] In this embodiment, the bottom end of the threaded rod 13 is rotatably installed in the bottom wall of the cavity. Multiple telescopic columns 22 are fixedly installed on the top of the rotary table 3. The top ends of the multiple telescopic columns 22 are all fixedly installed on the bottom of the support plate 15. A No. 1 motor 9 is fixedly installed on the outside of the rotary table 3. The output end of the No. 1 motor 9 is fixedly connected to one end of the rotating shaft 10, so that the rotating shaft 10 can be rotated by the No. 1 motor 9.

[0026] In this embodiment, a plurality of movable holes 21 are fixedly installed on the top of the workbench 4, and the outer sides of a plurality of L-shaped movable plates 19 are slidably connected to the corresponding movable holes 21, so that the L-shaped movable plates 19 are more stable when moving through the movable holes 21.

[0027] In this embodiment, when it is necessary to fix molds 5 of different sizes, the first motor 9 is started, which drives the rotating shaft 10 to rotate, thereby driving the first bevel gear 11 to rotate, which in turn drives the second bevel gear 12 meshing with the first bevel gear 11 to rotate, which in turn drives the threaded rod 13 to rotate, which in turn drives the threaded cylinder 14 threadedly connected to the threaded rod 13 to rotate, which in turn drives the support plate 15 to move vertically, which in turn drives the first hinge seat 16 to move vertically, which in turn drives the drive rod 17 to rotate, which in turn drives the second hinge seat 18 and the L-shaped moving part to rotate. The moving plate 19 begins to move along the moving hole 21, which in turn drives the clamping plate 20 to move along the moving hole 21, further removing the clamping plate 20 from fixing the mold 5. This facilitates the replacement of the mold 5, the circular top plate 6, and the T-shaped slider 7. After the replacement is completed, the above operation is repeated in reverse so that the clamping plate 20 re-fixes the mold 5, eliminating the need to replace the fixing device, thus reducing time consumption and greatly improving overall work efficiency and versatility. After the mold 5 is replaced, the nut 33 is disengaged from the screw 32 by turning the nut 33. The pull screw 32 facilitates the removal of the fixed connection between the rotating shaft 30 and the pressure plate 31, allowing for easy replacement of the pressure plate 31 that matches the mold 5. The workpiece is then placed inside the matching mold 5. The second hydraulic cylinder 27 is activated, causing the pressure plate 31 to move downwards into the mold 5, applying pressure to the workpiece. The second motor 29 is then activated, causing the rotating shaft 30 to rotate, which in turn rotates the pressure plate 31. Since the pressure plate 31 is in contact with the workpiece and mold 5, this rotation is also transmitted to the workpiece and mold 5. Simultaneously, due to the worktable... 4 is rotatable, so when the pressure plate 31, the workpiece, and the mold 5 rotate together, the worktable 4 will also rotate, thus ensuring that the workpiece obtains a uniform processing effect during the spinning process. After the workpiece is processed, the pressure plate 31 is disengaged from the mold 5 by activating the second hydraulic cylinder 27, and then the first hydraulic cylinder 24 is activated to drive the circular push block 25 to move vertically, which in turn drives the circular top plate 6, which is in contact with it, to move vertically, so that the circular top plate 6 pushes the processed workpiece out of the mold 5, thereby realizing rotational demolding, which greatly improves the processing efficiency.
