The bottom surface of the mold 16 is provided with a cross-shaped groove 17 and a top groove 15 that cooperate with the cross plate 4 and the bottom plate 18. The mold 16 can sit on the disc 3, and the cross plate 4 and the bottom plate 18 are inserted into the cross-shaped groove 17 and the top groove 15. The cylinder 10 is fixedly installed at the center of the top of the box 1. The telescopic end of the cylinder 10 is inside the box 1 and is fixedly connected to the mounting plate 13. A connecting rod 14 is rotatably installed at the center of the lower bottom surface of the mounting plate 13. The lower end of the connecting rod 14 is provided with a top retaining plate 6, and a top retaining groove 15 is provided at the center of the upper surface of the mold 16. The extension end of the cylinder 10 can extend to allow the top retaining plate 6 to be inserted into the top retaining groove 15. The spinning mechanism includes a spinning roller 7, an electric vertical moving component 8, and a horizontal moving component 9. The vertical moving component 8 is provided on the inner side wall of the housing 1, the horizontal moving component 9 is fixedly provided on the moving end of the vertical moving component 8, and the spinning roller 7 is fixedly provided on the moving end of the horizontal moving component 9. The spinning roller 7 can move the mold 16. The sheet metal is spun and formed; multiple limiting rods 12 are provided on the upper surface of the mounting plate 13 near the edge, and limiting holes 11 are provided on the top of the housing 1 corresponding to the positions of the limiting rods 12, with the limiting rods 12 vertically moving through the limiting holes 11; the top plate 6 is rectangular in shape, and the shape of the top slot 15 matches the shape of the top plate 6, allowing the top plate 6 to be inserted into the top slot 15; a plane bearing 19 is provided between the bottom of the disc 3 and the support plate 2; a chamfer 21 is provided on the upper edge of the bottom plate 18.

[0015] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows: According to the instruction manual Figure 1-4As can be seen, when this utility model is in operation, the personnel select the corresponding mold 16 according to the product model to be processed. It is necessary to pre-approve multiple models of mold 16, but all molds 16 are provided with cross slots 17 and bottom slots 5 of the same size at the bottom, and top slots 15 of the same size at the top. During installation, the personnel open the box door, place the mold 16 on the disc 3, and align the cross slots 17 and bottom slots 5 with the cross plates 4 and bottom plates 18. The cross plates 4 and bottom plates 18 are inserted into the cross slots 17 and bottom slots 5 to ensure circumferential and radial stability. The personnel then put the sheet metal material onto the mold 16. It should be understood that the sheet metal material is a semi-finished part, which is annular or frustum-shaped, which is common knowledge to those skilled in the art. At this time, the telescopic end of cylinder 10 extends, driving the mounting plate 13, connecting rod 14, and top clamping plate 6 to move downwards and insert into the top clamping groove 15 at the top of mold 16, ensuring the axial stability of mold 16. Motor 20 drives disc 3 and mold 16 to rotate. The horizontal moving component 9 and vertical moving component 8 in the spinning mechanism are both electric and can use a lead screw and lead nut to control the position of spinning roller 7, realizing the spinning forming of sheet metal raw materials. After processing, the top clamping plate 6 is lifted by cylinder 10 to remove the workpiece. When it is necessary to change the processed product, the top clamping plate 6 is lifted by cylinder 10, and the personnel can lift mold 16 upwards to remove it. This utility model, while facilitating the installation of sheet metal raw materials and ensuring the stability of mold 16 during operation, makes the disassembly and installation of mold 16 simple, convenient, and quick, allowing personnel to work easily and improving replacement efficiency.

[0016] The mounting plate 13 has multiple limiting rods 12 on its upper surface near the edge. The top of the housing 1 has limiting holes 11 corresponding to the positions of the limiting rods 12. The limiting rods 12 move vertically through the limiting holes 11 to ensure the stability of the vertical movement of the mounting plate 13, connecting rod 14 and top clamping plate 6 driven by the cylinder 10, and to increase the circumferential stability of the cylinder 10's extension end.

[0017] The top plate 6 is rectangular in shape, and the top slot 15 matches the shape of the top plate 6. The top plate 6 can be inserted into the top slot 15. The upper end of the connecting rod 14 is rotatably connected to the bottom surface of the mounting plate 13. Generally, a bearing is used. The top plate 6 is designed to be rectangular and fits into the top slot 15 of the mold 16, so that the connecting rod 14 and the mold 16 cannot rotate relative to each other, thus reducing wear between them.

[0018] A planar bearing 19 is provided between the bottom of the disc 3 and the support plate 2 to ensure the stability of the disc 3 and the mold 16 when they rotate.

[0019] The bottom plate 18 has a chamfer 21 on its upper edge to facilitate inserting the mold 16 into the top plate 6.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
