Description

Technical Field

[0001] This invention relates to the field of aluminum pot manufacturing and processing technology, and in particular to a device for thickening the rim of an aluminum non-stick pot by spinning and the thickening process thereof. Background Technology

[0002] Aluminum alloys are alloys with aluminum as the base and a certain amount of other alloying elements added. They are a type of lightweight metal material with high strength, a specific strength close to that of high alloy steel, and a specific stiffness exceeding that of steel. They also have good casting and plastic processing properties, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials. They are widely used in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily consumer goods.

[0003] Existing spinning pots are usually made of iron. Iron pots are prone to cracking during spinning. In addition, the thickness of the rim of existing iron pots is the same as the thickness of the body, which makes the structural strength of the rim less than ideal. When the pot is dropped, it is easy to break at the rim. This needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a device and process for thickening the rim of an aluminum non-stick pan by spinning, which can thicken the rim through secondary spinning, effectively improve processing accuracy and efficiency, and reduce manufacturing costs.

[0005] The above-mentioned technical objective of this invention is achieved through the following technical solution: a device for thickening the rim of an aluminum non-stick pan by spinning, comprising: The pot body spinning die is installed at the output end of the spinning machine; A feeding rack is used to continuously supply aluminum sheets; The multi-axis feeding mechanism includes a rotary pressure head, which is used to press and position the aluminum sheet on the pot body spinning mold. The spinning machine can drive the pot body spinning mold to drive the rotary pressure head to rotate synchronously through the aluminum sheet. The bottom periphery of the rotary pressure head is provided with an adsorption structure, which adsorbs and cooperates with the upper end surface of the aluminum sheet. The lifting and traversing mechanism and the rotating wheel are provided. The output end of the lifting and traversing mechanism is fixedly equipped with a mounting box. A drive arm is rotatably provided in the mounting box via a rotating shaft. A drive control adjustment mechanism is provided in the mounting box corresponding to the drive arm. The rotating wheel is rotatably mounted on the end of the drive arm. The rotating wheel includes a first spinning part and a second spinning part. The drive arm is adjusted and positioned in the mounting box by the drive control adjustment mechanism. The lifting and traversing mechanism can drive the drive arm to rotate along the rotating shaft through the drive control adjustment mechanism, so that the first spinning part or the second spinning part of the rotating wheel can be spun into a pot body spinning mold. The system includes a locking mechanism and a sensing control mechanism. The locking mechanism is located between the drive arm and the mounting box. The sensing control mechanism is used to detect the relative position of the drive arm with respect to the mounting box. When the drive control adjustment mechanism drives the drive arm to rotate, so that the first or second spinning part of the rotary wheel engages with the pot body spinning mold, the sensing control mechanism controls the locking mechanism to lock the drive arm with the mounting box.

[0006] By adopting the above technical solution, the multi-axis feeding mechanism uses the adsorption structure around the rotating pressure head to adsorb and transport the aluminum sheet from the feeding rack to the pot body spinning die. Then, the multi-axis feeding mechanism drives the rotating pressure head to press the aluminum sheet onto the pot body spinning die. Simultaneously, the lifting and traversing mechanism moves the mounting box to the side of the pot body spinning die. Then, the drive control adjustment mechanism makes the first spinning part of the rotating wheel contact the aluminum sheet. When the drive arm rotates and the first spinning part contacts the aluminum sheet, the induction control mechanism acts on the locking mechanism to lock the drive arm and the mounting box. The spinning machine drives the pot body spinning die to rotate. The pot body spinning die and the rotating pressure head clamp and cooperate to drive the aluminum sheet to rotate at high speed. The lifting and traversing mechanism drives the rotating wheel to move in space to change the spinning feed of the rotating wheel, thereby making the first spinning part of the rotating wheel cooperate with the pot body spinning die to form a pot body blank on the pot body spinning die. After the first stage of spinning is completed, the induction control mechanism acts on the locking mechanism to release the platen. The lock releases the drive arm from the mounting box. The drive control adjustment mechanism rotates the drive arm 45° within the mounting box. Simultaneously, the lifting and traversing mechanism drives the second spinning part of the rotating wheel to contact the pot blank. When the drive arm rotates and the second spinning part contacts the aluminum sheet, the sensing control mechanism activates the locking mechanism to lock the drive arm to the mounting box. The spinning machine drives the pot spinning die to rotate. The pot spinning die and the rotating pressure head clamp and cooperate to drive the aluminum sheet to rotate at high speed. The lifting and traversing mechanism drives the rotating wheel to move in space to change the spinning feed amount, thereby enabling the second spinning part of the rotating wheel to cooperate with the pot spinning die. Utilizing the plastic deformation of the aluminum material, the aluminum material on the bottom side of the pot blank is spun to the perimeter of the pot opening, achieving a thicker pot opening. This allows the pot body of the same weight to have stronger structural performance, indirectly saving manufacturing costs. It has the effect of thickening the pot opening through secondary spinning, effectively improving processing accuracy and efficiency, and reducing manufacturing costs.

[0007] A further configuration of the present invention is as follows: the drive control adjustment mechanism includes a drive control component, a first screw, an ejector sleeve, and a linkage rod installed in the mounting box; the drive control component can drive the first screw to rotate; the ejector sleeve has a first internal thread hole; the ejector sleeve is threadedly engaged with the first screw through the first internal thread hole; the drive arm includes a first rotating arm portion and a second rotating arm portion integrally formed; one end of the linkage rod is hinged to the ejector sleeve; and the other end of the linkage rod is hinged to the first rotating arm portion.

[0008] By adopting the above technical solution, the drive control component drives the first screw to rotate. The threaded engagement between the first screw and the ejector sleeve enables the ejector sleeve to make linear motion to push the linkage rod. Then, the linkage rod pushes the first rotating arm to drive the second rotating arm to rotate. By utilizing the linear ejection of the ejector sleeve and the linkage between the linkage rod and the drive arm, the present invention can improve the rotational driving force of the drive arm, enabling the present invention to provide a stronger output force for the rotation of the drive arm.

[0009] A further configuration of the present invention is as follows: the drive control assembly includes a drive motor, a worm gear, and a double gear; the first screw is provided with a gear engagement portion; the drive motor can drive the worm gear to rotate; and the worm gear is connected to the gear engagement portion via the double gear.

[0010] By adopting the above technical solution, the drive motor drives the worm to rotate, and the meshing action of the double gear with the worm and gear joint drives the first screw to rotate, thereby realizing the linear motion of the ejector sleeve.

[0011] A further configuration of the present invention is as follows: the locking mechanism includes a locking sleeve, a first locking hole, and a second locking hole; the locking sleeve is slidably disposed on the mounting box; the first locking hole and the second locking hole are formed on the mounting box; a second screw is rotatably disposed inside the driving arm; the sensing control mechanism can drive the second screw to rotate; the locking sleeve is provided with a second internal threaded hole; the second screw is threadedly engaged with the locking sleeve through the second internal threaded hole to drive the locking sleeve to extend and lock into the corresponding first locking hole and second locking hole.

[0012] By adopting the above technical solution, when the first or second spinning part of the spinning wheel presses the aluminum sheet on the spinning mold of the pot body, the locking force of the locking mechanism prevents the drive arm from rotating relative to the mounting box, thereby improving the running stability of the spinning process of the present invention.

[0013] A further configuration of the present invention is as follows: the second screw has a positive thread portion and a negative thread portion at both ends, and two locking sleeves are provided, the two locking sleeves respectively corresponding to the positive thread portion and the negative thread portion for threaded engagement, and the rotation of the second screw drives the locking sleeves on both sides to move closer or further apart.

[0014] By adopting the above technical solution, the symmetrically arranged locking sleeves can extend out relative to each other and lock with the two side walls of the mounting box, effectively improving the locking reliability between the drive arm and the mounting box of the present invention.

[0015] A further configuration of the present invention is as follows: the sensing control mechanism includes a motor drive module, a sensing switch, a first magnetic component and a second magnetic component, the first magnetic component corresponding to the first lock hole and the second magnetic component corresponding to the second lock hole are respectively fixed on the mounting box, the sensing switch is disposed on the drive arm, the sensing switch is inductively engaged with the first magnetic component or the second magnetic component, and controls the motor drive module to drive the second screw to rotate.

[0016] By adopting the above technical solution, when the drive arm rotates along the rotating shaft, and the first or second spinning part of the rotary wheel is spun into contact with the pot body spinning mold, the induction switch senses the first or second magnetic component at the corresponding position on the mounting box, and then feeds back to control the locking mechanism to quickly switch from the released state to the locked state.

[0017] A further feature of the present invention is that a suction hole is vertically opened in the middle of the pot body spinning mold, and a vacuum generating device connected to the suction hole is provided in the spinning machine, the vacuum generating device being used to create a vacuum adsorption force in the suction hole.

[0018] By adopting the above technical solution, when the aluminum sheet is placed on the pot body spinning die for spinning, the vacuum generator uses the suction hole to firmly suck the aluminum sheet onto the pot body spinning die, which can effectively reduce the deformation of the pot body due to centrifugal force during the spinning process, improve the processing accuracy of the pot body, and ensure the dimensional uniformity of each aluminum sheet after it is processed into a pot body.

[0019] A further feature of the present invention is that it also includes a defective product rejection mechanism, which includes a waste collection frame and a vision detection module electrically connected to the multi-axis feeding mechanism. The vision detection module is used to detect the aluminum sheet to be conveyed on the feeding rack and control the multi-axis feeding mechanism to convey the aluminum sheet to the pot body spinning mold or the waste collection frame.

[0020] By adopting the above technical solution, the aluminum sheet at the top of the feeding rack can be visually inspected in advance using the vision inspection module. If the aluminum sheet to be transported is found to be a qualified product, the multi-axis feeding mechanism will transport the aluminum sheet to the pot body spinning mold. If the aluminum sheet to be transported is found to be a defective product, the multi-axis feeding mechanism will transport the aluminum sheet to the waste collection box.

[0021] A further configuration of the present invention is as follows: the feeding rack has a loading cavity, the loading cavity is provided with a top plate and an elastic element, the upper end of the feeding rack has a clearance opening communicating with the loading cavity, and the diameter of the clearance opening is smaller than the diameter of the aluminum sheet, the side wall of the loading cavity has a feeding port communicating with the loading cavity and the clearance opening, and the elastic element always has a tendency to drive the top plate to push the aluminum sheet towards the clearance opening.

[0022] By adopting the above technical solution, the multi-axis feeding mechanism uses the adsorption structure of the rotating pressure head to remove the uppermost aluminum sheet in the feeding chamber. After the uppermost aluminum sheet of the feeding rack is removed, the elastic element uses its own elastic force to lift the top plate upward and push the lower aluminum sheet to the feeding port position.

[0023] Another technical objective of this invention is to provide a thickening process for an aluminum non-stick pan rim thickening device, comprising the following steps: S1: Aluminum sheet feeding: The multi-axis feeding mechanism uses the adsorption structure around the rotating pressure head to adsorb the aluminum sheet on the feeding rack and transport it to the pot body spinning mold. Then, the multi-axis feeding mechanism drives the rotating pressure head to press the aluminum sheet onto the pot body spinning mold. S2: Adjust the position of the spinning wheel: Move the mounting box to the side of the pot body spinning mold through the lifting and horizontal movement mechanism, and then use the drive control adjustment mechanism to make the first spinning part of the spinning wheel contact the aluminum sheet; S3: Locking: When the drive arm rotates and the first spinning part contacts the aluminum sheet, the sensing control mechanism acts on the locking mechanism to lock the drive arm and the mounting box in place. S3: First-stage spinning: The spinning machine drives the pot body spinning die to rotate. The pot body spinning die and the rotating pressure head clamp and cooperate to drive the aluminum sheet to rotate at high speed. The lifting and traversing mechanism drives the spinning wheel to move in space to change the spinning feed of the spinning wheel, thereby making the first spinning part of the spinning wheel cooperate with the pot body spinning die to form a pot body blank on the pot body spinning die. S4: Unlock: After the first stage of spinning is completed, the induction control mechanism unlocks the locking mechanism, so that the drive arm and the mounting box are in the released state; S5: Adjust the position of the rotating wheel: Drive the drive arm to rotate 45° in the mounting box through the drive control adjustment mechanism, and at the same time use the lifting and horizontal movement mechanism to drive the second spinning part of the rotating wheel to contact the pot blank. S6: Locking: When the drive arm rotates and the second spinning part contacts the aluminum sheet, the sensing control mechanism acts on the locking mechanism to lock the drive arm and the mounting box in place. S7: Secondary spinning: The spinning machine drives the pot body spinning die to rotate. The pot body spinning die and the rotating pressure head clamp and cooperate to drive the aluminum sheet to rotate at high speed. The lifting and traversing mechanism drives the spinning wheel to move in space to change the spinning feed of the spinning wheel. In turn, the second spinning part of the spinning wheel cooperates with the pot body spinning die to spin the aluminum material on the bottom side of the pot blank to the perimeter of the pot opening to achieve pot opening thickening.

[0024] In summary, the present invention has the following beneficial effects: The method employs a feeding rack, a multi-axis feeding mechanism, and a lifting and traversing mechanism located near the pot body spinning die. The multi-axis feeding mechanism uses an adsorption structure around the rotating pressure head to attract and transport aluminum sheets from the feeding rack to the pot body spinning die. Then, the multi-axis feeding mechanism drives the rotating pressure head to press the aluminum sheets firmly onto the pot body spinning die. The lifting and traversing mechanism and the drive control adjustment mechanism work together to adjust the rotating wheel so that its first or second spinning part is engaged with the pot body spinning die. In addition, a locking mechanism and a sensing control mechanism are set between the drive arm and the mounting box. The sensing control mechanism is used to detect the relative position of the drive arm with respect to the mounting box and control the locking mechanism to lock the drive arm and the mounting box in place. This method has the advantages of thickening the pot opening through secondary spinning, effectively improving processing accuracy and efficiency, and reducing manufacturing costs.

Detailed Implementation

[0038] The invention will now be further described with reference to the accompanying drawings.

[0039] A device for thickening the rim of an aluminum non-stick pan by spinning, such as... Figures 1-2 and Figure 4As shown, the machine includes a protective frame 10 with an automatic swing door. Inside the protective frame 10 are a pot body spinning die 1, a feeding rack 2, a multi-axis feeding mechanism 3, a lifting and traversing mechanism 4, a rotating wheel 41, a locking mechanism, and a sensing control mechanism. The pot body spinning die 1 is installed at the output end of the spinning machine 101. The feeding rack 2 continuously supplies aluminum sheets 9. The multi-axis feeding mechanism 3 includes an X-axis linear module 301, a Y-axis linear module 302, a Z-axis linear module 303, and a rotating pressure head 31. The Y-axis linear module 302 is driven by an electric cylinder, and the Z-axis linear module 303 is driven by a hydraulic cylinder 403. The rotating pressure head 31 presses and positions the aluminum sheets 9 onto the pot body spinning die 1. The spinning machine 101 can... The pot body spinning mold 1 drives the rotating pressure head 31 to rotate synchronously through the aluminum sheet 9. The bottom periphery of the rotating pressure head 31 is provided with an adsorption structure, which adsorbs and cooperates with the upper end surface of the aluminum sheet 9. In this embodiment, the adsorption structure is set as an adsorption hole opened in the bottom periphery of the rotating pressure head 31. The rotating pressure head 31 is provided with a vacuum mechanism to provide adsorption force to the adsorption hole. The lifting and horizontal movement mechanism 4 includes a vertically arranged lead screw pair structure 401, a sliding seat 402, and a hydraulic cylinder 403. The sliding seat 402 is fixed to the output end of the lead screw pair structure 401, the hydraulic cylinder 403 is horizontally fixed on the sliding seat 402, and the mounting box 40 is fixed to the piston rod end of the hydraulic cylinder 403. The mounting box 40 is rotatably provided with a drive arm 42 through a rotating shaft 420. In this embodiment, the drive arm 42 is assembled from two parts by fastening. A drive control adjustment mechanism 5 is provided within the mounting box 40 corresponding to the drive arm 42. A rotating wheel 41 is rotatably mounted at the end of the drive arm 42. The rotating wheel 41 includes a first spinning part 411 and a second spinning part 412. The drive arm 42 is adjusted and positioned within the mounting box 40 via the drive control adjustment mechanism 5. The lifting and traversing mechanism 4, through the drive control adjustment mechanism 5, can drive the drive arm 42 to rotate along the rotating shaft 420, causing the first spinning part 411 or the second spinning part 412 of the rotating wheel 41 to engage with the pot body spinning mold 1. A locking mechanism is located between the drive arm 42 and the mounting box 40. A sensing control mechanism is used to detect the relative position of the drive arm 42 relative to the mounting box 40. When the drive control adjustment mechanism... 5. Drive the drive arm 42 to rotate, so that when the first spinning part 411 or the second spinning part 412 of the spinning wheel 41 is spun into the pot body spinning mold 1, the sensing control mechanism controls the locking mechanism to lock the drive arm 42 into the mounting box 40; the pot body spinning mold 1 is provided with positioning mechanisms on both sides, and the positioning mechanisms are used to adjust the position of the aluminum sheet 9 placed on the spinning mold. The positioning mechanisms include Y-shaped positioning push rods 11 symmetrically arranged on both sides of the pot body spinning mold 1. The forked end of the Y-shaped positioning push rod 11 near the pot body spinning mold 1 is vertically provided with a positioning column. The cylinders on both sides push the Y-shaped positioning push rods 11 on both sides to approach each other and clamp the aluminum sheet 9 on the pot body spinning mold 1, so that the aluminum sheet 9 can be positioned and found on the pot body spinning mold 1;A suction hole 1a is vertically opened in the middle of the pot body spinning die 1. A vacuum generator connected to the suction hole 1a is installed inside the spinning machine 101. The vacuum generator creates a vacuum suction force within the suction hole 1a. When the aluminum sheet 9 is placed on the pot body spinning die 1 for spinning, the vacuum generator, acting on the suction hole 1a, firmly suctions the aluminum sheet 9 onto the pot body spinning die 1. This effectively reduces the deformation of the pot body due to centrifugal force during spinning, improves the processing accuracy of the pot body, and ensures the dimensional uniformity of each aluminum sheet 9 after processing into a pot body.

[0040] like Figures 5-10 As shown, the drive control adjustment mechanism 5 includes a drive control component 51, a first screw 52, ​​an ejector sleeve 53, and a linkage rod 54 installed in the mounting box 40. The drive control component 51 can drive the first screw 52 to rotate. The ejector sleeve 53 has a first internal threaded hole 53a, and the ejector sleeve 53 is threadedly engaged with the first screw 52 through the first internal threaded hole 53a. The drive arm 42 includes an integrally formed first rotating arm portion 421 and a second rotating arm portion 422. One end of the linkage rod 54 is hinged to the ejector sleeve 53, and the other end of the linkage rod 54 is hinged to the first rotating arm portion 421. The drive control component 51 drives the first screw 52 to rotate. By utilizing the threaded engagement between the first screw 52 and the ejector sleeve 53, the ejector sleeve 53 can make linear motion to push the linkage rod 54. Then, the linkage rod 54 pushes the first rotating arm portion 421. The second rotating arm 422 is driven to rotate. This invention utilizes the linear ejection of the ejector sleeve 53 and the linkage between the linkage rod 54 and the drive arm 42 to improve the rotational driving force of the drive arm 42, enabling the invention to provide a stronger output force for the rotation of the drive arm 42. The drive control component 51 includes a drive motor 511, a worm gear 512, and a double gear 513. The first screw 52 is provided with a gear engagement part 521. The drive motor 511 can drive the worm gear 512 to rotate. The worm gear 512 is connected to the gear engagement part 521 through the double gear 513. The drive motor 511 drives the worm gear 512 to rotate. By utilizing the meshing action of the double gear 513 with the worm gear 512 and the gear engagement part 521, the first screw 52 is driven to rotate, thereby realizing the linear movement of the ejector sleeve 53.

[0041] like Figures 8-12As shown, the locking mechanism includes a locking sleeve 61, a first locking hole 40a, and a second locking hole 40b. The locking sleeve 61 is slidably mounted on the mounting box 40. The first locking hole 40a and the second locking hole 40b are formed on the mounting box 40. A second screw 62 is rotatably mounted inside the drive arm 42. A sensing control mechanism can drive the second screw 62 to rotate. The locking sleeve 61 has a second internal threaded hole 61a. The second screw 62 is threadedly engaged with the locking sleeve 61 through the second internal threaded hole 61a, which drives the locking sleeve 61 to extend and lock into the corresponding first locking hole 40a and second locking hole 40b. This prevents the drive arm 42 from being positioned relative to the aluminum sheet 9 on the pot body spinning die 1 when the first spinning part 411 or the second spinning part 412 of the spinning wheel 41 presses the aluminum sheet 9. The installation box 40 rotates, thereby improving the operational stability of the spinning process of the present invention. The second screw 62 has a positive thread 621 and a negative thread 622 at both ends. Two locking sleeves 61 are provided, each corresponding to a threaded engagement with the positive thread 621 and the negative thread 622, respectively. The rotation of the second screw 62 drives the locking sleeves 61 to move closer or further apart. The symmetrically arranged locking sleeves 61 can extend relative to each other and lock against the side walls of the installation box 40, effectively improving the locking reliability between the drive arm 42 and the installation box 40. Furthermore, the locking sleeves 61 have protruding sliding portions 611 on both sides. The drive arm 42 has sliding holes corresponding to the locking sleeves 61 and the sliding portions 611, allowing the locking sleeves 61 to slide through the sliding portions 611. The induction control mechanism includes a motor drive module 71, an induction switch 72, a first magnetic element 404, and a second magnetic element 405. The first magnetic element 404 is fixed to the first locking hole 40a, and the second magnetic element 405 is fixed to the second locking hole 40b. The induction switch 72 is located on the drive arm 42. The induction switch 72 engages with the first magnetic element 404 or the second magnetic element 405 and controls the motor drive module 71 to drive the second screw 62 to rotate. When the drive arm 42 rotates along the rotating shaft 420, causing the first spinning part 411 or the second spinning part 412 of the rotating wheel 41 to engage with the pot body spinning mold 1, the induction switch 72 senses the first magnetic element 404 or the second magnetic element 405 at the corresponding position on the mounting box 40. The component 405 provides feedback control to quickly switch the locking mechanism from the released state to the locked state. In this embodiment, the motor drive module 71 includes a micro motor 711, an active bevel gear 712, and a driven bevel gear 713. The micro motor 711 drives the active bevel gear 712 to rotate. The driven bevel gear 713 is coaxially fixed in the middle of the second screw 62, and the active bevel gear 712 and the driven bevel gear 713 mesh. A rolling damping structure is provided between the mounting box 40 and the drive arm 42. The rolling damping structure includes a track groove 406 and a reduction gear 423. The reduction gear 423 is rotatably mounted on the drive arm 42, and the track groove 406 is provided on the mounting box 40. The reduction gear meshes with the toothed track 406a inside the track groove 406.

[0042] like Figures 1-3 As shown, the protective frame 10 also includes a defective product rejection mechanism 8. The defective product rejection mechanism 8 includes a waste collection frame 81 and a vision inspection module 82 electrically connected to the multi-axis feeding mechanism 3. The vision inspection module 82 is used to detect the aluminum sheet 9 to be conveyed on the feeding rack 2 and controls the multi-axis feeding mechanism 3 to convey the aluminum sheet 9 to the pot body spinning mold 1 or the waste collection frame 81. The vision inspection module 82 can pre-visually inspect the aluminum sheet 9 at the top of the feeding rack 2. If the aluminum sheet 9 to be transported is detected as a qualified product, the multi-axis feeding mechanism 3 transports the aluminum sheet 9 to the pot body spinning mold 1. If the aluminum sheet 9 to be transported is detected as a defective product, the multi-axis feeding mechanism 3 transports the aluminum sheet 9 to the waste collection frame 81. In section 1; the feeding rack 2 has a loading cavity 2a, and the loading cavity 2a has a top plate 21 and an elastic element 22. The upper end of the feeding rack 2 has a clearance opening 2b that connects to the loading cavity 2a, and the diameter of the clearance opening 2b is smaller than the diameter of the aluminum sheet 9. The side wall of the loading cavity 2a has a feeding port 2c that connects the loading cavity 2a and the clearance opening 2b. The elastic element 22 always has the tendency to drive the top plate 21 to push the aluminum sheet 9 toward the clearance opening 2b. The multi-axis feeding mechanism 3 uses the adsorption structure of the rotating pressure head 31 to remove the uppermost aluminum sheet 9 in the loading cavity 2a. After the uppermost aluminum sheet 9 of the feeding rack 2 is removed, the elastic element 22 uses its own elastic force to push the top plate 21 upward and push the lower aluminum sheet 9 to the feeding port 2c position.

[0043] The basic working principle of this invention is as follows: The multi-axis feeding mechanism 3 uses the adsorption structure around the rotating pressure head 31 to adsorb and transport the aluminum sheet 9 on the feeding rack 2 to the pot body spinning mold 1. Then, the multi-axis feeding mechanism 3 drives the rotating pressure head 31 to press the aluminum sheet 9 onto the pot body spinning mold 1. At the same time, the lifting and traversing mechanism 4 drives the mounting box 40 to move to the side of the pot body spinning mold 1. Then, the drive control adjustment mechanism 5 makes the first spinning part 411 of the rotating wheel 41 contact the aluminum sheet 9. When the drive arm 42 rotates, the first spinning part 411 contacts the aluminum sheet 9. Upon contact, the induction control mechanism activates the locking mechanism to lock the drive arm 42 and the mounting box 40 in place. The spinning machine 101 drives the pot body spinning die 1 to rotate. The pot body spinning die 1 and the rotating pressure head 31 clamp and cooperate to drive the aluminum sheet 9 to rotate at high speed. The lifting and traversing mechanism 4 drives the spinning wheel 41 to move in space to change the spinning feed of the spinning wheel 41, thereby making the first spinning part 411 of the spinning wheel 41 engage with the pot body spinning die 1 to form a pot body blank on the pot body spinning die 1 with the aluminum sheet 9. After the first stage of spinning is completed, the induction control mechanism activates... The locking mechanism unlocks, releasing the drive arm 42 from the mounting box 40.

Simultaneously, the lifting and traversing mechanism 4 drives the second spinning part 412 of the rotating wheel 41 to contact the pot blank. When the drive arm 42 rotates and the second spinning part 412 contacts the aluminum sheet 9, the sensing control mechanism activates the locking mechanism to lock the drive arm 42 to the mounting box 40. The spinning machine 101 drives the pot body spinning mold 1 to rotate, and the pot body spinning mold 1 clamps and engages with the rotating pressure head 31. The aluminum sheet 9 is driven to rotate at high speed, and the lifting and traversing mechanism 4 drives the rotating wheel 41 to move in space to change the spinning feed of the rotating wheel 41. This causes the second spinning part 412 of the rotating wheel 41 to cooperate with the pot body spinning mold 1. By utilizing the plastic deformation of the aluminum material, the aluminum material on the bottom side of the pot body blank is spun to the periphery of the pot mouth to thicken the pot mouth. This allows the pot body of the same quality to have stronger structural performance, indirectly saving manufacturing costs. It has the effect of thickening the pot mouth through secondary spinning, effectively improving processing accuracy and efficiency, and reducing manufacturing costs.

S2: Adjust the position of the spinning wheel: Move the mounting box to the side of the pot body spinning mold through the lifting and horizontal movement mechanism, and then use the drive control adjustment mechanism to make the first spinning part of the spinning wheel contact the aluminum sheet; S3: Locking: When the drive arm rotates and the first spinning part contacts the aluminum sheet, the sensing control mechanism acts on the locking mechanism to lock the drive arm and the mounting box in place. S3: First-stage spinning: The spinning machine drives the pot body spinning die to rotate. The pot body spinning die and the rotating pressure head clamp and cooperate to drive the aluminum sheet to rotate at high speed. The lifting and traversing mechanism drives the spinning wheel to move in space to change the spinning feed of the spinning wheel, thereby making the first spinning part of the spinning wheel cooperate with the pot body spinning die to form a pot body blank on the pot body spinning die. S4: Unlock: After the first stage of spinning is completed, the induction control mechanism unlocks the locking mechanism, so that the drive arm and the mounting box are in the released state; S5: Adjust the position of the rotating wheel: Drive the drive arm to rotate 45° in the mounting box through the drive control adjustment mechanism, and at the same time use the lifting and horizontal movement mechanism to drive the second spinning part of the rotating wheel to contact the pot blank. S6: Locking: When the drive arm rotates and the second spinning part contacts the aluminum sheet, the sensing control mechanism acts on the locking mechanism to lock the drive arm and the mounting box in place. S7: Secondary spinning: The spinning machine drives the pot body spinning die to rotate. The pot body spinning die and the rotating pressure head clamp and cooperate to drive the aluminum sheet to rotate at high speed. The lifting and traversing mechanism drives the spinning wheel to move in space to change the spinning feed of the spinning wheel. In turn, the second spinning part of the spinning wheel cooperates with the pot body spinning die to spin the aluminum material on the bottom side of the pot blank to the perimeter of the pot opening to achieve pot opening thickening.
