Process for cold spinning of surface pattern on stainless steel vessel

Abstract

This invention discloses a cold spinning process for creating patterns on the surface of stainless steel containers. The process includes a spindle housing, a control console, a spinning mechanism, a mounting frame, and a base. A forming mold is fixedly mounted on one side of the top of the spindle housing. One side of the spindle housing is fixedly connected to one end of the base. The control console is fixedly mounted on the outer wall of the spindle housing. By holding a movable rod and rotating a steering plate, the spinning roller is controlled to move closer to the outside of the sheet metal. The operator controls the rotation shaft to apply a certain force, causing the spinning roller to apply pressure to the sheet metal, deforming it to conform to the surface of the forming mold. Repeating the rotation of the movable rod and steering plate multiple times applies pressure to the sheet metal surface. As the sheet metal rotates, it undergoes continuous point-by-point deformation, gradually forming the pattern. The use of wear-resistant and high-temperature-resistant spinning rollers significantly reduces workload, multiplies efficiency, and improves the working environment. Furthermore, it allows for better contact and forming of the pattern between the sheet metal and the surface of the forming mold.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A rotating shaft 322 is movably sleeved on the outer wall of the pressure rod 321. A spinning roller 325 is rotatably connected to one end of the rotating shaft 322. The spinning roller 325 is made of a special wear-resistant and high-temperature resistant plastic material (polyurethane material, high temperature resistance and wear resistance). A support plate 326 is provided on one side of the spinning roller 325. One end of the support plate 326 is fixedly connected to the outer wall of the rotating shaft 322.

A limit groove 39 is provided on the bottom surface of the adjusting shaft 39. 1. A locking block 392 is movably connected to the inner wall of the limiting groove 391. A second spring 393 is fixedly connected between the locking block 392 and the inner wall of the limiting groove 391. The pressure block 43 is pushed by the hydraulic cylinder 41 to press the sheet metal tightly against the forming mold 11. The motor of the main spindle housing 1 is started to drive the forming mold 11 to rotate at high speed, causing the sheet metal and the pressure block 43 to rotate synchronously. By holding the movable rod 324 and rotating the steering plate 32, the spinning roller 325 is controlled to move closer to the outside of the sheet metal. The operator controls the rotating shaft 322 to rotate and apply a certain force to make the spinning roller 325 apply pressure to the sheet metal, causing the sheet metal to deform and adhere to the surface of the forming mold 11. During the spinning process of the sheet metal, the steering plate 32 is moved to make the sheet metal... The adjusting shaft 39 moves within the slot 33 to adjust the rotation center of the steering plate 32. The elastic deformation of the second spring 393 causes the locking block 392 to contract during the movement of the adjusting shaft 39, automatically engaging with the inner wall of the slot 33. The rotation of the movable rod 324 and the steering plate 32 is repeated multiple times, causing the spinning roller 325 to apply pressure to the surface of the sheet material. As the sheet material rotates, it undergoes continuous point-by-point deformation and gradually takes shape. The spinning roller 325, which is wear-resistant and high-temperature resistant, greatly reduces the workload and increases efficiency several times over. The working environment is significantly improved, and the sheet material and the surface pattern of the forming mold 11 make better contact and take shape. The pattern is clear and polished after processing. No further processing is required to meet the quality requirements.

By placing the stainless steel sheet to be processed on the placement groove 371, the center of the sheet is automatically aligned with the axis of the forming mold 11, which facilitates the user to quickly perform the feeding operation and improves the processing efficiency.

[0036] according to Figure 5 - Figure 6 As shown, a shrinkage groove 372 is provided at one end of the placement groove 371. A movable block 373 is provided inside the shrinkage groove 372.

The bottom end of the first spring 374 is fixedly connected to the bottom surface of the inner wall of the shrinkage groove 372. The movable block 373 provides a certain limit to stabilize the plate material. When the plate material is pushed, the movable block 373 shrinks in the shrinkage groove 372. After the plate material is clamped, the first spring 374 automatically rebounds.

[0037] according to Figure 5 As shown, a telescopic plate 38 is fixedly connected to one end of the feeding table 37.

With the setting of the telescopic plate 38, the user can place a certain number of plates on the telescopic plate 38. The telescopic plate 38 extends and retracts, causing the limit plate 381 to clamp and fix the plates, which makes it convenient for the user to quickly remove the plates for subsequent processing after processing, making it convenient for the user.

[0038] according to Figure 1 - Figure 3As shown, a protective plate 5 is provided on the side of the base 6 away from the spinning mechanism 3.

[0039] according to Figure 4 As shown, one end of the base 6 is fixedly installed with the servo motor 62, and the shaft end of the servo motor 62 is fixedly connected with the lead screw 63. One end of the lead screw 63 passes through the interior of the traction block 64 and is rotatably connected to the outer wall of the spindle housing 1. The lead screw 63 and the traction block 64 are threadedly connected. The servo motor 62 drives the lead screw 63 to rotate, thereby moving the traction block 64 and adjusting the position of the fixing frame 4 on the spindle housing 1.

[0040] according to Figure 1 and Figure 5 As shown, a guide shaft 7 is fixedly connected to the outer wall of the front of the base 6. One end of the guide shaft 7 is fixedly connected to the outer wall of the main shaft housing 1. A slider 71 is movably sleeved on the outer wall of the guide shaft 7. One side of the slider 71 is fixedly connected to the outer wall of the fixing plate 31. A locking bolt 35 is threadedly connected to the lower outer wall of the fixing plate 31. One end of the locking bolt 35 contacts the outer wall of the guide shaft 7. By moving the slider 71 on the guide shaft 7, the user can adjust the position of the spinning mechanism 3. The outer wall of the guide shaft 7 is pressed and fixed by the rotation of the locking bolt 35, which makes it easier for the steering plate 32 to better control the spinning range of the spinning roller 325, thus facilitating better spinning and forming of the sheet metal.

[0041] according to Figure 5 As shown, a fixed block 323 is fixedly connected to one end of the rotating shaft 322 away from the spinning roller 325. One end of the movable rod 324 passes through the outer wall of the fixed block 323. The movable rod 324 is movably connected to the fixed block 323. The movement of the movable rod 324 on the fixed block 323 makes it easy for the user to adjust the extension length of the movable rod 324, thereby making it easier for the user to control the spinning roller 325 to apply pressure to the sheet material with less effort, which is convenient for the user.

[0042] The operating method and working principle of this device are as follows: First, the stainless steel sheet to be processed is placed on the placement groove 371. The movable block 373 is used to limit the placement of the sheet to ensure its stability. Then, the hydraulic cylinder 41 pushes the pressure block 43 to press and fix the sheet on the placement groove 371 tightly against the forming mold 11. Then, the handle 51 is used to pull the protective plate 5 to shield and protect the top of the forming mold 11. The motor of the main spindle housing 1 is started to drive the forming mold 11 to rotate at high speed, causing the sheet and pressure block 43 to rotate synchronously. Then, the operator holds the movable rod 324 and the steering plate 32 to rotate and control the spinning roller 325 to move closer to the outside of the sheet. The guide wheel 327 guides the sheet to contact and move. The operator controls the rotation shaft 322 to rotate and apply pressure. A certain force is applied to the spinning roller 325 to press the sheet metal, causing the sheet metal to deform and adhere to the surface of the forming mold 11. During the spinning process, the operator moves the steering plate 32 to move the adjusting shaft 39 within the slot 33. The elastic deformation of the second spring 393 causes the locking block 392 to retract during the movement of the adjusting shaft 39, automatically locking the inner wall of the slot 33. By repeatedly rotating the movable rod 324 and the steering plate 32, the spinning roller 325 applies pressure to the surface of the sheet metal. As the sheet metal rotates, it undergoes continuous point-by-point deformation and gradually takes shape. After processing, the operator activates the hydraulic cylinder 41 to retract the pressure block 43, releasing the pressure between the formed part and the forming mold 11, and then removes the formed part from the forming mold 11.
