It is usually used to manufacture thin-walled cylinders or conical parts with complex shapes, such as water tanks, boiler shells, automobile fuel tanks, etc. The spinning technology is applicable to the processing of stainless steel and other metal materials. In the spinning process, the stainless steel plate is fixed on the workbench of the spinning machine tool, and at the same time, a rotating tool applies uniform pressure to the plate. During the rotation process, the plate is subjected to gradually increasing pressure, causing the plate to plastically deform, so as to obtain the expected shape; the stainless steel plate spinning devices in the prior art usually cannot achieve fully automatic stainless steel plate spinning, and have a large number of power sources and complex controls. Summary of the Invention

[0004] Further, the installation mechanism includes a fixed disk fixedly installed on the placing table, a rotating disk is rotatably installed on the fixed disk, a central gear is fixedly installed on the rotating disk, a protruding column is arranged below the pressing block, and holes corresponding to the protruding column of the pressing block are arranged on the rotating disk and the stainless steel plate.

[0006] After the stainless steel plate is placed on the rotating disk through the pressing block, the centers of the stainless steel plate, the pressing block and the rotating disk are concentric. The motor drives the motor gear to rotate, thereby driving the lower gear, the side shaft, the upper gear and the top gear to rotate, thereby driving the central gear and the rotating disk to rotate, and thereby driving the stainless steel plate to rotate.

[0007] Further, the spinning mechanism includes a lower rotating plate rotatably installed on the placing table, a spinning plate is rotatably installed on the lower rotating plate, a strong spring is arranged between the spinning plate and the lower rotating plate, and a spinning wheel is rotatably installed on the spinning plate.

[0008] Further, an inner rotating rod is rotatably installed on the lower rotating plate, an internally threaded block is rotatably installed on the inner rotating rod, a vertical lead screw is rotatably installed on the placing table, an upper docking gear is fixedly installed on the vertical lead screw, the upper docking gear meshes with the upper gear, and the vertical lead screw and the internally threaded block form a screw drive.

[0009] The rotation of the upper gear drives the rotation of the upper docking gear and the vertical lead screw, thereby driving the upward movement of the internally threaded block. Then, the lower rotating plate is driven to rotate through the inner rotating rod, so that the spinning wheel contacts the lower surface of the stainless steel plate. And in cooperation with the rotation of the stainless steel plate, the stainless steel plate is folded and pressed onto the pressing block by the spinning wheel. When the stainless steel plate is closely attached to the pressing block, the lower rotating plate continues to rotate, so that the spinning wheel moves along the stainless steel plate, and the spinning plate rotates relative to the lower rotating plate, and the strong spring is stretched. Furthermore, the spinning wheel presses the entire stainless steel plate onto the pressing block, completing the spinning of the stainless steel plate. At this time, the upper surface of the stainless steel plate is completely attached to the lower surface of the pressing block.

[0010] Further, the feeding mechanism includes a bottom oil cylinder fixedly installed on the bottom plate. A rotating rod is rotatably installed at the output end of the bottom oil cylinder. An upper sliding arm is rotatably installed on the rotating rod. A vertical rod is rotatably installed on the upper sliding arm, and the vertical rod is fixedly installed with the bottom plate. A placing seat is fixedly installed on the bottom plate. A placing column is arranged on the placing seat. The stainless steel plate to be processed is placed on the placing seat, and the hole on the stainless steel plate is located on the placing column of the placing seat.

[0011] Further, a sliding frame is slidably installed on the upper sliding arm. A horizontal electric cylinder is rotatably installed on the sliding frame.

A connecting frame is fixedly installed below the moving seat, and the connecting frame is fixedly installed with the pressing block.

[0012] Further, a vacuum generator is arranged inside the pressing block.

[0013] During use, the bottom oil cylinder extends slightly. The contraction of the horizontal electric cylinder drives the sliding frame to slide along the upper sliding arm, causing the pressing block to reach above the placement seat. At this time, the horizontal electric cylinder contracts to the innermost position. Subsequently, the bottom oil cylinder contracts, causing the protruding column at the bottom of the pressing block to insert into the hole of the stainless steel plate located on the placement seat. Then, the vacuum generator inside the pressing block is activated, causing the stainless steel plate to be adsorbed below the pressing block. Subsequently, the upper sliding arm extends to the longest, and the bottom oil cylinder extends to the longest. The moving seat slides along the inclination of the upper sliding arm towards the vertical rod through the rollers. When the moving seat moves to the limit position, the pressing block and the stainless steel plate are located above the rotating disk. Subsequently, the bottom oil cylinder contracts, causing the stainless steel plate to be docked with the rotating disk, and the protruding column of the pressing block to insert into the hole of the rotating disk. After the spinning of the stainless steel plate is completed, the vacuum generator inside the pressing block is turned off, causing the stainless steel plate to stay on the rotating disk. Under the action of the bottom oil cylinder and the upper sliding arm, the pressing block moves above the placement seat again for the next feeding of the stainless steel plate, and the operator removes the spun stainless steel plate on the rotating disk.

[0014] The beneficial effects of the present invention compared with the prior art are as follows: (1) The installation mechanism provided in the present invention drives the stainless steel plate to be spun to rotate, and through three sets of continuously rising spinning mechanisms, the stainless steel plate is continuously pressed onto the pressing block, thereby spinning the stainless steel plate into a shape that fits the pressing block, with high spinning efficiency; (2) The lower rotating plate and the spinning plate of the spinning mechanism provided in the present invention can rotate relative to each other and are connected by a strong spring, so that the spinning wheel always presses the stainless steel plate against the pressing block during the upward movement along with the internal thread block, resulting in good spinning effect; (3) The feeding mechanism provided in the present invention can automatically move the stainless steel plate to be spun onto the installation mechanism, and automatically move the spun stainless steel plate out of the installation mechanism after spinning. There is no need for personnel to position and install the stainless steel plate above the spinning mechanism, reducing potential safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following further describes the detailed embodiment of the present invention with reference to the accompanying drawings.

[0024] Embodiment: Refer to Figures 1-7 , a stainless steel plate spinning device, including an installation mechanism for installing the stainless steel plate 4 to be spun. The installation mechanism includes a placement table 101 and a pressing block 105. A base 102 is fixedly installed below the placement table 101.

[0025] As Figures 2-4 shown, the installation mechanism includes a fixed disk 103 fixedly installed on the placement table 101. A rotating disk 104 is rotatably installed on the fixed disk 103. A central gear 106 is fixedly installed on the rotating disk 104. A protruding column is provided below the pressing block 105. Holes corresponding to the protruding column of the pressing block 105 are provided on the rotating disk 104 and the stainless steel plate 4.

[0026] As Figures 2-4 shown, three motors 107 are fixedly installed on the placement table 101. A motor gear 108 is fixedly installed on the motor shaft of the motor 107. Three side shafts 109 are rotatably installed on the placement table 101. A top gear 112, an upper gear 111 and a lower gear 110 are fixedly installed on the side shaft 109. The lower gear 110 meshes with the motor gear 108, and the top gear 112 meshes with the central gear 106.

[0027] After the stainless steel plate 4 is placed on the rotating disk 104 by the pressing block 105, the centers of the stainless steel plate 4, the pressing block 105 and the rotating disk 104 are concentric, and the motor 107 drives the motor gear 108 to rotate, thereby driving the lower gear 110, the side shaft 109, the upper gear 111 and the top gear 112 to rotate, thereby driving the central gear 106 and the rotating disk 104 to rotate, thereby driving the stainless steel plate 4 to rotate.

[0029] like Figure 5 As shown, an inner rotating rod 205 is rotatably installed on the lower rotating plate 201, an inner thread block 206 is rotatably installed on the inner rotating rod 205, a vertical screw rod 207 is rotatably installed on the placement table 101, an upper docking gear 208 is fixedly installed on the vertical screw rod 207, the upper docking gear 208 is meshed with the upper gear 111, and the vertical screw rod 207 and the inner thread block 206 form a threaded transmission.

[0030] The rotation of the upper gear 111 drives the upper docking gear 208 and the vertical screw rod 207 to rotate, thereby driving the internal thread block 206 to rise, thereby driving the lower rotating plate 201 to rotate through the inner rotating rod 205, so that the spinning wheel 204 contacts the lower surface of the stainless steel plate 4, and cooperates with the rotation of the stainless steel plate 4 to fold the stainless steel plate 4 and press it onto the pressing block 105 through the spinning wheel 204. When the stainless steel plate 4 is close to the pressing block 105, the lower rotating plate 201 continues to rotate, so that the spinning wheel 204 moves along the stainless steel plate 4, and the spinning plate 202 and the lower rotating plate 201 rotate relative to each other, and the strong spring 203 is stretched, so that the spinning wheel 204 presses the stainless steel plate 4 completely onto the pressing block 105, completing the spinning of the stainless steel plate 4. At this time, the upper surface of the stainless steel plate 4 is completely in contact with the lower surface of the pressing block 105.

[0031] like Figure 6 , Figure 7 As shown, the loading mechanism includes a bottom cylinder 302 fixedly mounted on a bottom plate 301, a rotating rod 304 is rotatably mounted on the output end of the bottom cylinder 302, an upper sliding arm 305 is rotatably mounted on the rotating rod 304, a vertical rod 303 is rotatably mounted on the upper sliding arm 305, the vertical rod 303 is fixedly mounted on the bottom plate 301, a placing seat 308 is fixedly mounted on the bottom plate 301, a placing column is arranged on the placing seat 308, a stainless steel plate 4 to be processed is placed on the placing seat 308, and the holes on the stainless steel plate 4 are located on the placing columns of the placing seat 308.

[0032] like Figure 6 ,Figure 7 As shown, a sliding frame 307 is slidably mounted on the upper sliding arm 305. A horizontal electric cylinder 306 is rotatably mounted on the sliding frame 307. The output end of the horizontal electric cylinder 306 is rotatably mounted with the upper sliding arm 305. A moving seat 309 is slidably mounted in the upper sliding arm 305. A roller 310 is rotatably mounted on the moving seat 309. The roller 310 rolls in the upper sliding arm 305. A connecting frame 311 is fixedly mounted below the moving seat 309. The connecting frame 311 is fixedly mounted with the pressing block 105.

[0033] As Figure 6 、 Figure 7 shown, a vacuum generator is provided in the pressing block 105.

[0034] During use, the bottom oil cylinder 302 extends slightly. The contraction of the horizontal electric cylinder 306 drives the sliding frame 307 to slide along the upper sliding arm 305, so that the pressing block 105 reaches above the placing seat 308. At this time, the horizontal electric cylinder 306 contracts to the innermost. Then the bottom oil cylinder 302 contracts, so that the protruding column at the bottom of the pressing block 105 is inserted into the hole of the stainless steel plate 4 located on the placing seat 308. Then the vacuum generator in the pressing block 105 is started, so that the stainless steel plate 4 is adsorbed below the pressing block 105. Then the upper sliding arm 305 extends to the longest, and the bottom oil cylinder 302 extends to the longest. The moving seat 309 slides along the inclination of the upper sliding arm 305 towards the vertical rod 303 through the roller 310. When the moving seat 309 moves to the limit position, the pressing block 105 and the stainless steel plate 4 are located above the rotating disc 104. Then the bottom oil cylinder 302 contracts, so that the stainless steel plate 4 is docked with the rotating disc 104, and the protruding column of the pressing block 105 is inserted into the hole of the rotating disc 104. After the stainless steel plate 4 is spin-pressed, the vacuum generator in the pressing block 105 is turned off, so that the stainless steel plate 4 stays on the rotating disc 104. Under the action of the bottom oil cylinder 302 and the upper sliding arm 305, the pressing block 105 moves above the placing seat 308 again for the next loading of the stainless steel plate 4. The operator takes away the spin-pressed stainless steel plate 4 on the rotating disc 104.

[0035] The working principle of a spinning device for stainless steel plates disclosed in the present invention is as follows: When in use, the bottom oil cylinder 302 extends slightly. The contraction of the horizontal electric cylinder 306 drives the sliding frame 307 to slide along the upper sliding arm 305, so that the pressing block 105 reaches above the placement seat 308. At this time, the horizontal electric cylinder 306 contracts to the innermost position. Subsequently, the bottom oil cylinder 302 contracts, so that the protruding column at the bottom of the pressing block 105 is inserted into the hole of the stainless steel plate 4 located on the placement seat 308. Then, the vacuum generator in the pressing block 105 is started, so that the stainless steel plate 4 is adsorbed below the pressing block 105. Subsequently, the upper sliding arm 305 extends to the longest, the bottom oil cylinder 302 extends to the longest, and the moving seat 309 slides along the inclination of the upper sliding arm 305 towards the vertical rod 303 through the rollers 310. When the moving seat 309 moves to the limit position, the pressing block 105 and the stainless steel plate 4 are located above the rotating disk 104. Subsequently, the bottom oil cylinder 302 contracts, so that the stainless steel plate 4 is docked with the rotating disk 104, and the protruding column of the pressing block 105 is inserted into the hole of the rotating disk 104. After placing the stainless steel plate 4 on the rotating disk 104 through the pressing block 105, the centers of the stainless steel plate 4, the pressing block 105, and the rotating disk 104 are concentric. The motor 107 drives the motor gear 108 to rotate, thereby driving the lower gear 110, the side shaft 109, the upper gear 111, and the top gear 112 to rotate, thereby driving the central gear 106 and the rotating disk 104 to rotate, and thus driving the stainless steel plate 4 to rotate. The rotation of the upper gear 111 drives the upper docking gear 208 and the vertical lead screw 207 to rotate, thereby driving the internal thread block 206 to rise, and thus driving the lower rotating plate 201 to rotate through the internal rotating rod 205, so that the spinning wheel 204 contacts the lower surface of the stainless steel plate 4, and in cooperation with the rotation of the stainless steel plate 4, the stainless steel plate 4 is folded and pressed onto the pressing block 105 through the spinning wheel 204. When the stainless steel plate 4 is closely attached to the pressing block 105, the lower rotating plate 201 continues to rotate, so that the spinning wheel 204 moves along the stainless steel plate 4, and the spinning plate 202 rotates relative to the lower rotating plate 201, and the strong spring 203 is stretched. Furthermore, the spinning wheel 204 presses the entire stainless steel plate 4 onto the pressing block 105 to complete the spinning of the stainless steel plate 4. At this time, the upper surface of the stainless steel plate 4 is completely attached to the lower surface of the pressing block 105. After the spinning of the stainless steel plate 4 is completed, the vacuum generator in the pressing block 105 is turned off, so that the stainless steel plate 4 stays on the rotating disk 104. Under the action of the bottom oil cylinder 302 and the upper sliding arm 305, the pressing block 105 moves above the placement seat 308 again for the next feeding of the stainless steel plate 4, and the operator takes away the spun stainless steel plate 4 on the rotating disk 104.

[0036] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
