Abstract
Description
Technical Field
[0001] This invention belongs to the field of air fryer pot body processing technology, and in particular relates to a stamping and cutting mold for an air fryer pot body and its usage method. Background Technology
[0002] As the core structural component and main heating chamber of an air fryer, the pot body's processing quality and production efficiency directly affect the overall product's capacity and manufacturing cost. In current air fryer pot body manufacturing processes, a multi-stage assembly line operation is typically employed. Specifically, the traditional processing technology, in sequence, includes: cutting the sheet material, stamping the sheet material, cutting the sides, punching holes, bending, and blanking, among other steps.
[0003] In actual production line layouts, each of the above processing steps requires a separate processing station, and adjacent processing stations also need to be equipped with transfer mechanisms. This not only results in a longer overall production cycle time and a larger equipment footprint, but also leads to higher production costs. Furthermore, multiple transfers can easily introduce processing errors, which is detrimental to ensuring the dimensional accuracy of the produced pots. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a stamping and cutting mold for an air fryer pot body and a method for using it, which helps to shorten the production cycle, reduce the floor space, and ultimately reduce production costs.
[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a stamping and cutting mold for an air fryer pot body, including a worktable, a fixed mold and a movable mold located above the fixed mold and movable up and down, the upper end of the fixed mold is recessed downward to form a contour groove, the bottom of the contour groove is provided with a mounting hole, a pusher is inserted into the mounting hole, the lower end of the pusher is connected to a reset component, the reset component is used to make the pusher extend upward out of the mounting hole so that the upper end surface of the pusher is flush with the upper end surface of the fixed mold in the initial state; The lower end of the moving mold is provided with a punching head and an annular cutter for shearing sheet metal. The annular cutter surrounds the periphery of the punching head. The punching head includes a fixed head and a floating head distributed vertically. The fixed head is fixedly connected to the moving mold. The floating head is sleeved on the fixed head and slides vertically with the fixed head. The fixed mold is provided with a clearance groove corresponding to the annular cutter. During the process of the moving mold moving down and cooperating with the fixed mold to stamp the sheet metal, the floating head first cooperates with the pusher to clamp the sheet metal, then the annular cutter cooperates with the clearance groove to shear the sheet metal, and finally the fixed head and the floating head force the sheet metal into the contour groove to complete the stamping of the pot body.
[0006] Preferably, the reset assembly includes a U-shaped conduit and a counterweight. One end of the U-shaped conduit is connected to the lower end of the mounting hole, and the other end of the U-shaped conduit is provided with a housing. The counterweight is disposed in the housing and slides vertically against the inner wall of the housing. A piston extending into the U-shaped conduit is fixedly disposed at the lower end of the counterweight. The lower end of the pusher extends into the U-shaped conduit. A sealed space is formed in the U-shaped conduit between the piston and the pusher. The sealed space is filled with liquid. The total weight of the counterweight and the piston is greater than the sum of the weights of the pusher and the floating head in the non-pressing state, so as to provide a constant clamping force before pressing.
[0007] Preferably, the mounting hole includes an upper hole section and a lower hole section that are coaxially distributed, the inner diameter of the upper hole section is larger than the inner diameter of the lower hole section, and a limiting step surface is formed at the connection between the upper hole section and the lower hole section. The pushing member includes an upper rod body and a lower rod body, the upper rod body is adapted to the upper hole section, and the lower rod body passes through the lower hole section and extends into the U-shaped guide tube.
[0008] Preferably, the housing includes a shell with an opening at the top and a cover that covers the top of the shell. A displacement sensor is installed on the cover for real-time monitoring of the vertical displacement of the counterweight. The displacement sensor is electrically connected to a controller and is used to determine the stamping depth and reset status of the stamping head.
[0009] Preferably, the upper end of the fixing head protrudes outward along the circumferential direction to form a first flange, and the lower end of the first flange is provided with an annular groove and an annular limiting plate. The upper end of the floating head is provided with a groove that matches the fixed head. The upper end of the floating head protrudes outward along the circumferential direction to form a second flange. The second flange is movably accommodated in the annular groove. The annular limiting plate blocks the lower end of the second flange. When the floating head is pressed and moves upward relative to the fixed head to its limit position, the bottom of the groove abuts against the lower end of the fixed head, and at the same time, the upper end of the second flange abuts against the bottom of the annular groove, so that the fixed head and the floating head cooperate to form a rigid whole.
[0010] Preferably, a waste collection mechanism is provided on the side of the workbench away from the box. The waste collection mechanism includes a vertical moving module, a horizontal moving module, a U-shaped frame, and a material frame. The vertical moving module is used to drive the horizontal moving module to move up and down, and the horizontal moving module is used to drive the U-shaped frame to move horizontally. Multiple suction cups for grabbing waste are provided below the U-shaped frame. The U-shaped frame can reciprocate between the top of the fixed mold and the top of the material frame under the coordinated drive of the vertical moving module and the horizontal moving module.
[0011] And a method for using a stamping and cutting die for an air fryer pot body, including the following steps: S1. Loading: Lay the sheet material to be processed flat on the upper surface of the fixed mold; S2, Positioning and clamping: The moving mold moves down, so that the floating head abuts against the plate to be processed, and the floating head and the pusher cooperate to clamp the plate; S3, Shearing: The moving die continues to move downward, and the annular cutter and the clearance groove cooperate to shear the sheet material to be processed. The sheet material inside the annular cutter forms a stamped sheet, and the sheet material outside the annular cutter becomes waste. S4. Merging stamping heads: The moving die continues to move downward, and the floating head is obstructed and slides upward relative to the fixed head until the bottom of the groove abuts against the lower end of the fixed head. At the same time, the upper end of the second flange abuts against the bottom of the annular groove, and the fixed head and the floating head merge into a rigid stamping head. S5, Stamping: The moving die continues to move downward, and the combined stamping head presses the stamping sheet to overcome the pushing force of the reset component and enter the contour groove to form a pot body. During this process, the pushing component moves downward and the counterweight moves upward. S6. Reset and demolding: The moving mold moves upward, the counterweight moves downward under the action of gravity, and the pusher moves upward. The pusher automatically pushes the formed pot body out of the contour groove. S7. Transferring the pot body: The robotic arm picks up the pot body and transfers it to the next processing station; S8. Waste cleaning: The up-and-down moving module and the lateral moving module of the waste collection mechanism work together to grab the waste left on the fixed mold through the suction cup on the U-shaped frame and transfer it into the material frame.
[0012] Compared with the prior art, the advantages of the present invention are as follows: 1. This solution integrates shearing and stamping functions. After one mold closing stroke, the moving mold can automatically, continuously and accurately complete the outer cutting of the sheet metal and the stamping of the pot body, realizing multiple uses of one mold. This not only helps to reduce procurement costs and factory floor space, but also eliminates the secondary positioning error caused by the transfer of sheet metal between different workstations, significantly improving the production cycle and the dimensional consistency of the final pot body. 2. The reset assembly uses components such as U-shaped conduit, liquid and counterweight. The constant gravity of the counterweight is conducted through the liquid to provide a relatively stable thrust for the pusher during the entire stamping process. Compared with the nonlinear elastic force of traditional spring pressure material that increases dramatically with the amount of compression, it has better stability. 3. An innovative composite stamping head was designed, including a fixed head and a floating head with independent sliding stroke. Relying on the mechanical interference between the components when the moving die moves downward, the strict process sequence of the floating head pre-clamping, the ring cutter closing and shearing, and the merging of the stamping heads is realized. This sequence does not require the intervention of active electronic control systems such as servo motors and sensors, and has a high fault tolerance rate and stable and reliable operation.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0016] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0017] Example 1: As Figure 1 and Figure 2 As shown, a stamping and cutting die for an air fryer pot body includes a workbench 1, a fixed die 2 on the workbench 1, and a movable die 3 located above the fixed die 2 and movable up and down. The upper end of the fixed die 2 is recessed downward to form a contour groove 21. A through mounting hole 22 is provided at the center of the bottom of the contour groove 21. A pusher 4 is slidably inserted in the mounting hole 22. The lower end of the pusher 4 is connected to a reset assembly 5. The reset assembly 5 is used to apply an upward pushing force to the pusher 4, so that the pusher 4 extends upward out of the mounting hole 22, so that the upper end surface of the pusher 4 is flush with the upper end surface of the fixed die 2 in the initial state.
[0018] In this embodiment, the lower end of the moving die 3 is provided with a punching head 31 and an annular cutter 32 for shearing sheet metal, and the annular cutter 32 surrounds the periphery of the punching head 31. The punching head 31 is a composite structure, including a fixed head 311 and a floating head 312 distributed vertically. The fixed head 311 is fixedly connected to the moving die 3, and the floating head 312 is sleeved on the fixed head 311 and slides vertically with the fixed head 311. The fixed die 2 is provided with a relief groove 23 corresponding to the annular cutter 32.
[0019] During the process of moving mold 3 moving down and cooperating with fixed mold 2 to stamp the sheet metal, floating head 312 first cooperates with pusher 4 to clamp the sheet metal, then annular cutter 32 cooperates with clearance groove 23 to cut the sheet metal, and finally the fixed head 311 and floating head 312 force the sheet metal into the contour groove 21 to complete the stamping of the pot body.
[0020] It should be noted that this solution uses the reset component 5 to make the upper surface of the pusher 4 flush with the upper surface of the fixed mold 2 in the initial state, providing support for the placed sheet metal. At the same time, it provides an upward thrust to the pusher 4 before stamping, thereby cooperating with the floating head 312 to pre-clamp the sheet metal, which can prevent the sheet metal from deforming, wrinkling or misaligning when subjected to shearing force, thus ensuring that the annular cutter 32 accurately cuts the sheet metal.
[0021] Example 2: Figure 2 and Figure 3As shown, the rest of the components are the same as in Embodiment 1, except that the reset assembly 5 adopts a purely mechanical-hydraulic structure, including a U-shaped conduit 51 and a counterweight 52. One end of the U-shaped conduit 51 is connected to the lower end of the mounting hole 22, and the other end of the U-shaped conduit 51 is provided with a housing 53. The counterweight 52 is disposed in the housing 53 and slides up and down with the inner wall of the housing 53. The lower end of the counterweight 52 is fixedly provided with a piston 521 extending into the U-shaped conduit 51. The lower end of the pusher 4 extends into the U-shaped conduit 51. The U-shaped conduit 51 forms a closed space between the piston 521 and the pusher 4. The closed space is filled with liquid 54 (such as hydraulic oil). The overall weight of the counterweight 52 and the piston 521 is set to be greater than the sum of the weights of the pusher 4 and the floating head 312 in the non-pressing state, so as to provide a constant clamping force before pressing. It should be noted that the U-shaped conduit 51 has an injection port with a sealing plug in the middle (not shown in the figure) for injection or pressure relief maintenance.
[0022] In this embodiment, the mounting hole 22 is a stepped hole, including an upper hole section 221 and a lower hole section 222 coaxially distributed. The inner diameter of the upper hole section 221 is larger than the inner diameter of the lower hole section 222, and a limiting step surface is formed at the connection between the upper hole section 221 and the lower hole section 222. Correspondingly, the pusher 4 includes an upper rod body 41 and a lower rod body 42. The upper rod body 41 is adapted to the upper hole section 221, and the lower rod body 42 passes through the lower hole section 222 and extends into the U-shaped guide tube 51. The lower rod body 42 also serves as a piston. With this structural design, during stamping, the upper rod body 41 moves downward and abuts against the limiting step surface. The limiting step surface can improve the supporting force and prevent the upper rod body 41 from moving downward excessively.
[0023] In this embodiment, the housing 53 includes a shell 531 with an opening at the top and an upper cover 532 covering the upper end of the shell 531. A displacement sensor 6 is installed on the upper cover 532 for real-time monitoring of the vertical displacement of the counterweight 52. The displacement sensor 6 is electrically connected to a controller (not shown in the figure) and is used to determine the stamping depth and reset status of the stamping head 31. Details are as follows: 1. In the initial state (before mold closing), the height of counterweight 52 is H1; 2. When the plate is pre-clamped, the height of the counterweight 52 is H2; 3. When the mold is closed, the height of the counterweight 52 is H3; 4. When the mold is demolded and the pot body is pressed on the pusher 4, the height of the counterweight 52 is H4.
[0024] By pre-setting safety thresholds for the aforementioned height parameters within the controller, the system monitors the height of the counterweight 52 at each action node in real time. When a value deviates from the threshold range, the system triggers an alarm to alert personnel to inspect or maintain the equipment. This non-contact monitoring method effectively avoids the harsh stamping environment, significantly extends sensor lifespan, and helps ensure the reliability of automated mold operation.
[0025] Example 3: Figure 2 and Figure 4 As shown, the rest of the parts are the same as in Embodiment 1, except that the upper end of the fixing head 311 protrudes outward along the circumferential direction to form a first flange 3111, and the lower end of the first flange 3111 is provided with an annular groove 3112 and an annular limiting plate 3113.
[0026] In this embodiment, the upper center of the floating head 312 is provided with a groove 3121 that matches the fixed head 311, and the upper end of the floating head 312 protrudes outward in the circumferential direction to form a second flange 3122. During assembly, the second flange 3122 is movably accommodated in the annular groove 3112, and the annular limiting plate 3113 blocks the lower end of the second flange 3122 to prevent the floating head 312 from falling off.
[0027] When the floating head 312 is pressed and moves upward relative to the fixed head 311 to its limit position, the bottom of the groove 3121 abuts against the lower end of the fixed head 311, and at the same time the upper end of the second flange 3122 abuts against the bottom of the annular groove 3112, so that the fixed head 311 and the floating head 312 cooperate to form a rigid whole.
[0028] This method innovatively designs a composite stamping head 31, with a floating head 312 having an independent sliding stroke. Relying on the mechanical interference between the components when the moving die 3 moves downward, it realizes a strict process sequence such as pre-clamping of the floating head 312, closing shearing of the annular cutter 32, and merging of the stamping head 31. This sequence does not require the intervention of active electronic control systems such as servo motors and sensors, and has a high fault tolerance rate and stable and reliable operation.
[0029] Example 4: Figure 1 , Figure 2 and Figure 5As shown, the rest of the parts are the same as in Embodiment 1, except that a waste collection mechanism 7 is provided on the side of the workbench 1 away from the box 53. The waste collection mechanism 7 includes a vertical moving module 71, a horizontal moving module 72, a U-shaped frame 73 and a material frame 74. The vertical moving module 71 is used to drive the horizontal moving module 72 to move up and down, and the horizontal moving module 72 is used to drive the U-shaped frame 73 to move horizontally. Multiple suction cups 75 for grabbing waste are provided below the U-shaped frame 73. The U-shaped frame 73 can reciprocate between the top of the fixed mold 2 (grabbing position) and the top of the material frame 74 (dispensing position) under the coordinated drive of the vertical moving module 71 and the horizontal moving module 72.
[0030] Furthermore, the middle part of the U-shaped frame 73 is connected to the transverse moving module 72, and the opening of the U-shaped frame 73 faces the fixed mold 2 to adapt to the shape of the waste material while avoiding the stamped pot body; the suction cup 75 is usually a vacuum suction cup.
[0031] In actual automated production line layouts, stamping and cutting dies, as the core processing link, are typically arranged sequentially along a straight line with other loading and unloading equipment (e.g., distributed along the X-axis). The feeding end of the stamping and cutting die is equipped with a conveying mechanism, which lays the sheet metal to be processed flat onto the upper surface of the fixed die 2. The discharge end of the stamping and cutting die is equipped with a robotic arm, which transfers the stamped pot body to the next workstation. The aforementioned conveying mechanism and robotic arm are conventional technologies in this field and will not be elaborated upon here. It should be noted that, in order to achieve spatial avoidance in assembly line operations and prevent interference between mechanisms, the waste collection mechanism 7, the center of the workbench 1, and the box 53 in this embodiment are distributed along the Y-axis (i.e., perpendicular to the material flow direction of the production line).
[0032] Example 5: A method for using the stamping and cutting die for the air fryer pot body described in Examples 1 to 4 above, comprising the following steps: S1. Loading: Lay the sheet material to be processed flat on the upper surface of the fixed mold; S2, Positioning and clamping: The moving mold moves down, so that the floating head abuts against the plate to be processed, and the floating head and the pusher cooperate to clamp the plate; S3, Shearing: The moving die continues to move downwards. While the sheet metal is clamped, the annular cutter and the clearance groove work together to shear the sheet metal to be processed. The sheet metal inside the annular cutter forms a stamped sheet, while the sheet metal outside the annular cutter becomes waste. S4. Merging stamping heads: The moving die continues to move downward, and the floating head is obstructed and slides upward relative to the fixed head until the bottom of the groove abuts against the lower end of the fixed head. At the same time, the upper end of the second flange abuts against the bottom of the annular groove, and the fixed head and the floating head merge into a rigid stamping head. S5, Stamping: The moving die continues to move downward, and the combined stamping head presses the stamping sheet to overcome the pushing force of the reset component and enter the contour groove to form a pot body. During this process, the pushing component moves downward and the counterweight moves upward. S6. Reset and demolding: The moving mold moves upward, the counterweight moves downward under the action of gravity, and the pusher moves upward. The pusher automatically pushes the formed pot body out of the contour groove. S7. Transferring the pot body: The robotic arm picks up the pot body and transfers it to the next processing station; S8. Waste cleaning: The up-and-down moving module and the lateral moving module of the waste collection mechanism work together to grab the waste left on the fixed mold through the suction cup on the U-shaped frame and transfer it into the material frame.
[0033] It should be noted that steps S7 and S8 can be performed simultaneously.
[0034] As can be seen, this solution integrates shearing and stamping functions. The moving mold can automatically, continuously and accurately complete the outer cutting of the sheet metal and the stamping of the pot body after one mold closing stroke, realizing multiple uses of one mold. This not only helps to reduce procurement costs and factory floor space, but also eliminates the secondary positioning error caused by the transfer of sheet metal between different workstations, significantly improving the production cycle and the dimensional consistency of the final pot body.
[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.

S5, Stamping: The moving die continues to move downward, and the combined stamping head presses the stamping sheet to overcome the pushing force of the reset component and enter the contour groove to form a pot body. During this process, the pushing component moves downward and the counterweight moves upward. S6. Reset and demolding: The moving mold moves upward, the counterweight moves downward under the action of gravity, and the pusher moves upward. The pusher automatically pushes the formed pot body out of the contour groove. S7. Transferring the pot body: The robotic arm picks up the pot body and transfers it to the next processing station; S8. Waste cleaning: The up-and-down moving module and the lateral moving module of the waste collection mechanism work together to grab the waste left on the fixed mold through the suction cup on the U-shaped frame and transfer it into the material frame.
