[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figure 1-Figure 4 A CNC spinning forming equipment for cookware includes an operating table 1, a mold 4 on the operating table 1, a support 2 fixedly installed on the operating table 1, a movable component 6 in the support 2, a movable frame 64 in the movable component 6, a telescopic component 7 connected to one side of the movable frame 64, a frame 76 in the telescopic component 7, a motor 71 installed inside the frame 76, a threaded rod 72 connected to the output end of the motor 71, the threaded rod 72 being rotatably disposed inside the telescopic frame 73, the telescopic frame 73 being fixedly connected to the frame 76, a telescopic plate 74 adapted and slidably disposed inside the telescopic frame 73, the telescopic plate 74 being helically connected to the threaded rod 72, a movable rod 75 fixedly installed on the telescopic plate 74, the movable rod 75 passing through the telescopic frame 73 and fixedly connected to a connecting plate 8, and a pressure roller 81 installed on the connecting plate 8;

[0023] One end of the connecting plate 8 is equipped with a flame nozzle 9, which is connected to the gas supply pipe 91. The gas supply pipe 91 passes through the limiting frame 92, which is fixedly installed on the movable frame 64.

[0024] The movable frame 64 in the movable component 6 is screwed to the threaded rod 62. The threaded rod 62 is rotatably mounted on the bracket 2. The two sides of the threaded rod 62 are parallel and vertically arranged with slide rods 63. The movable frame 64 is slidably mounted on the slide rods 63. The threaded rod 62 is connected to the output end of the motor 61.

[0025] Specifically, firstly, the moving component 6 and the telescopic component 7 are used to control the position and movement of the pressure roller 81. The second motor 61 is started, driving the second threaded rod 62 to rotate. Since the moving frame 64 is spirally connected to the second threaded rod 62 and slides on the slide rod 63, the moving frame 64 can move precisely in the vertical direction, which can quickly and accurately position the pressure roller 81 at the appropriate height above the metal sheet and the mold 4. At the same time, the first motor 71 is started, driving the first threaded rod 72 to rotate. Since the telescopic plate 74 is spirally connected to the first threaded rod 72, the telescopic plate 74 slides inside the telescopic frame 73. The telescopic plate 74 drives the moving rod 75, which in turn moves the connecting plate 8 and the pressure roller 81 closer to the metal sheet, preparing for spinning.

[0026] The metal sheet is placed on the mold 4 on the operating table 1. The mold 4 determines the basic shape and size of the cookware. The mold 4 starts to rotate under the drive, causing the metal sheet to rotate as well. At this time, under the coordinated control of motor 71 and motor 61, the pressure roller 81 applies pressure to the rotating metal sheet with specific pressure, feed speed and motion trajectory according to the preset CNC program. Under the action of the pressure roller 81, the metal sheet gradually conforms to the shape of the mold 4, realizing spin forming.

[0027] During the spinning process, when auxiliary heating of the metal sheet is required, gas is supplied to the burner 9 through the gas pipe 91, and the burner 9 emits flames to heat the metal sheet. The limiting bracket 92 is used to fix the gas pipe 91 to ensure that the burner 9 can stably heat the sheet during movement. This helps to improve the plasticity of the material and better complete the spinning process, especially for the processing of cookware with high hardness.

[0028] By combining the motor and the screw (motor 2 61 and screw rod 2 62, motor 1 71 and screw rod 1 72), the position of the pressure roller 81 can be precisely controlled, thereby ensuring the accuracy of parameters such as the feed amount and pressing depth of the pressure roller 81 during the spinning process, thus improving the dimensional and shape accuracy of the cookware, and ultimately achieving precise completion of the cookware forming according to the design requirements.

[0029] Example 2:

[0030] To achieve mold 4 replacement and stable rotation, please refer to... Figure 1-Figure 4 Based on embodiment 1, mold 4 is mounted on turntable 13, and positioning rod 14 is fixedly provided on turntable 13. Positioning rod 14 is adapted to the groove at the bottom of mold 4. Turntable 13 is connected to the output end of motor 3 12. Motor 3 12 is mounted on operating table 1 through support platform 11.

[0031] An electric telescopic rod 3 is installed on the bracket 2. The center of the electric telescopic rod 3 and the turntable 13 are on the same axis. A pressure plate 5 is rotatably connected to the output end of the electric telescopic rod 3.

[0032] Specifically, the mold 4 is mounted on the turntable 13, and the positioning rod 14 on the turntable 13 is adapted to the groove at the bottom of the mold 4. This not only serves a positioning function during the installation of the mold 4, but also prevents radial displacement of the mold 4 during rotation. At the same time, the electric telescopic rod 3 and the pressure plate 5 fix the mold 4 from above through the metal plate, keeping the mold 4 stable in the vertical direction. The combination of upper and lower fixing methods ensures that the mold 4 will not shake or shift during high-speed rotation, thereby ensuring the stability and precision of the spinning process.

[0033] When mold 4 needs to be replaced, first stop the operation of motor 12 to stop the turntable 13 from rotating. Then, retract the electric telescopic rod 3, causing the pressure plate 5 to lift upwards and detach it from above mold 4. Next, by pulling mold 4 upwards along positioning rod 14, the original mold 4 can be removed from turntable 13. When installing the new mold 4, align the groove at the bottom of mold 4 with positioning rod 14 on turntable 13, and then insert mold 4 downwards along positioning rod 14, ensuring that mold 4 is accurately placed on turntable 13, completing the replacement of mold 4. Afterwards, after placing the metal sheet on mold 4, activate the electric telescopic rod 3 to move the pressure plate 5 downwards, pressing it onto the newly installed mold 4 for easy spinning.

[0034] Working principle: When the equipment is in use, start motor 61 and motor 71. Motor 61 drives threaded rod 62 to rotate, causing the moving frame 64 to move precisely vertically with the help of the spiral connection with threaded rod 62 and the guide of slide rod 63, positioning the pressure roller 81 at a suitable height above the metal sheet and mold 4. Motor 71 drives threaded rod 72 to rotate, causing telescopic plate 74 to slide within telescopic frame 73, moving moving rod 75, connecting plate 8 and pressure roller 81 closer to the metal sheet, preparing for spinning. The metal sheet is then placed on the mold mounted on turntable 13. On plate 4, mold 4 is positioned and installed by fitting the positioning rod 14 on turntable 13 through the bottom slot. The electric telescopic rod 3 on bracket 2 extends, causing the pressure plate 5 at the output end to press onto the metal plate, combining with mold 4 to fix the metal plate and ensure its stability. Motor 3 12 can drive turntable 13 to rotate the metal plate. At this time, under the coordinated control of motor 1 71 and motor 2 61, pressure roller 81 applies pressure to the rotating metal plate with specific pressure, feed speed and motion trajectory according to the preset CNC program, so that the metal plate gradually conforms to the shape of mold 4, realizing spin forming. If heating assistance is required during processing, gas is delivered to the flame nozzle 9 through gas pipe 91 to heat the metal plate, which is beneficial for cookware processing.
