Description
Technical Field
[0001] This invention relates to the field of punching equipment technology, specifically to a punching device for the outer shell of a rice cooker. Background Technology
[0002] An electric rice cooker is a kitchen appliance specifically designed for cooking rice. It cooks rice by heating and generating steam. An electric rice cooker generally consists of an inner pot, a heating plate, and an outer shell. The outer shell of the electric rice cooker is the external protective shell that covers the internal structure of the rice cooker. It is usually made of metal materials, such as stainless steel or aluminum alloy. It serves to protect the internal components of the rice cooker, insulate against heat and the external environment, and also provides a beautiful appearance and easy cleaning.
[0003] To facilitate user observation and operation of the rice cooker's status, punching machines are used to perforate the rice cooker's outer shell during production. This allows for the installation of displays, indicator lights, or other control panel components. Furthermore, the rice cooker generates heat during operation; punching holes in the shell adds ventilation openings or heat dissipation holes, improving heat dissipation and preventing overheating. Rice cooker shells are typically made of metal materials such as stainless steel or aluminum alloy. Different materials have different elasticity and plasticity properties; softer or thin-walled materials are more prone to deformation. This results in unevenness or concavity at the punching locations on stainless steel or aluminum alloy rice cooker shells. To meet product quality and appearance requirements, workers must meticulously correct these unevennesses after punching, increasing production time and efficiency, and also increasing the workload for workers. Therefore, we propose a rice cooker shell punching device. Summary of the Invention

[0008] Preferably, the curved surface of the abutment plate is the same as the inner curved surface of the rice cooker shell, and the surface of the abutment plate is provided with a connecting groove that is the same shape as the punched hole in the shell.
[0009] Preferably, the inner wall of the rotating cylinder is provided with a rotating component that can drive the rotating cylinder to rotate. The rotating component includes a drive plate that is slidably connected to the inner wall of the rotating cylinder. A compression spring is fixedly connected to the bottom of the drive plate. One end of the compression spring is fixedly connected to the main body of the punch press. A locking block is fixedly connected to the end of the drive plate away from the compression spring. A locking groove that can engage with the locking block is opened on the inner wall of the piston plate. A rubber block that can drive the rotating cylinder to rotate is fixedly connected to the outer side of the drive plate. A limiting groove that can slidably connect with the rubber block is opened on the inner wall of the rotating cylinder.
[0010] Preferably, the limiting groove has two descending sections and two ascending sections. One end of the ascending section is connected to the bottom of the descending section, and the other end of the ascending section is connected to the top of the remaining descending section. The depth of the descending section increases from shallow to deep, and the depth of the ascending section decreases from deep to shallow.
[0011] Preferably, the two ascending sections are respectively provided with limiting members at the intersection to prevent the rubber block from slipping onto the wrong track.

Compared to existing technologies where, to meet product quality and appearance requirements, workers still need to meticulously correct any unevenness on the rice cooker's outer shell after punching, increasing production time and efficiency, and also increasing workload, this application addresses this issue by using a pressing mechanism to reshape the rice cooker's outer shell during the punching process. The inner side of the punching position is squeezed to prevent the nearby metal from bulging towards the rotating cylinder when the punch press body punches the rice cooker shell, thus reducing the deformation of the rice cooker shell. After punching, the abutting mechanism will drive the rotating cylinder and the rice cooker shell to the shaping mechanism. Through the cooperation of the abutting mechanism and the shaping mechanism, the punching position of the rice cooker shell can be adjusted again to ensure that the appearance of the rice cooker shell does not change significantly after punching. This makes it easier for workers to observe whether the punching of the rice cooker shell meets the requirements, reduces the production process, and improves the production efficiency of rice cooker shells.

Detailed Implementation
[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.
[0028] Example 1
[0029] Please see Figure 1-7 This invention provides a technical solution: a punching device for the outer shell of a rice cooker, comprising a punching machine body 1, a hydraulic rod 2 fixedly connected to the surface of the punching machine body 1, and a fixed plate 3 fixedly connected below the hydraulic rod 2; a support plate 4, located above the punching machine body 1 and below the fixed plate 3, with a rotating cylinder 5 fixedly connected below the support plate 4, and the rotating cylinder 5 rotatably connected to the inner wall of the punching machine body 1; an abutting mechanism 6, located outside the rotating cylinder 5, capable of pressing the punching position on the inner wall of the rice cooker outer shell; and a shaping mechanism 7, located on the surface of the punching machine body 1, capable of shaping the punching position of the outer shell after punching the rice cooker outer shell.
[0030] During use, the operator places the rice cooker shell upside down on top of the support plate 4, activates the hydraulic rod 2, and the hydraulic rod 2 pushes the fixing plate 3 downward. The fixing plate 3 and the support plate 4 clamp and fix the rice cooker shell. Simultaneously, the downward movement of the fixing plate 3 activates the abutment mechanism 6, which presses against the punched area on the inner wall of the rice cooker shell. The punching machine body 1 is activated, and depending on the punching requirements, some or all of the punching equipment on the surface of the punching machine body 1 operates to punch holes in the rice cooker shell. The abutment mechanism 6 presses against the inner side of the punched area during the punching process, thus preventing the punching machine body 1 from pressing against the rice cooker shell. When the rice cooker shell is punched, the nearby metal protrudes towards the rotating cylinder 5, reducing the degree of deformation of the rice cooker shell. The operation of the punching equipment of the punching body will drive the shaping mechanism 7 into the preparation stage. After the punching is completed, the abutting mechanism 6 drives the rotating cylinder 5 and the rice cooker shell to rotate, so that the punching position of the rice cooker shell moves to correspond with the position of the shaping mechanism 7. Through the cooperation of the abutting mechanism 6 and the shaping mechanism 7, the punching position of the rice cooker shell can be adjusted again to ensure that the appearance shape of the rice cooker shell does not change significantly after punching. This makes it convenient for the staff to observe whether the punching of the rice cooker shell meets the requirements, reduces the production process, and improves the production efficiency of the rice cooker shell.
[0031] The abutting mechanism 6 includes a fixed box 60 fixedly connected to the outside of the rotating cylinder 5. A moving rod 61 is slidably connected to the inner wall of the fixed box 60. An abutting plate 62 is fixedly connected to the end of the moving rod 61 away from the fixed box 60. The curved surface of the abutting plate 62 is the same as the inner curved surface of the rice cooker shell so that the abutting plate 62 can fit against the inner surface of the rice cooker shell. A connecting groove 68 with the same shape as the punching hole in the shell is opened on the surface of the abutting plate 62 so that when the punching equipment of the punching machine body 1 punches the shell, the punching equipment can pass through the connecting groove 68. A driving member 63 is provided on the inner wall of the fixed box 60 to push the moving rod 61 to slide on the inner wall of the fixed box 60.
[0032] After the worker places the outer shell upside down on the outside of the support plate 4, the hydraulic rod 2 pushes the fixed plate 3 closer to the support plate 4. The fixed plate 3 drives the drive component 63 to work, and the drive component 63 drives the moving rod 61 to slide along the inner wall of the fixed box 60. The moving rod 61 drives the abutment plate 62 to move, so that the abutment plate 62 abuts against the inner wall surface of the rice cooker outer shell. Thus, when the punching body 1 punches the surface of the rice cooker outer shell, the abutment plate 62 abuts against the inner wall of the rice cooker outer shell, which can prevent the punching body 1 from causing the nearby metal to bulge towards the rotating cylinder 5 when punching the rice cooker outer shell, thus reducing the degree of deformation of the rice cooker outer shell. After punching is completed, the hydraulic rod 2 retracts and drives the fixed plate 3 to rise, so that the drive component 63 drives the rotating cylinder 5 and the abutment plate 62 to rotate. The pressure of the abutment plate 62 on the rice cooker outer shell causes the rice cooker outer shell to rotate, so that the punching position of the rice cooker outer shell rotates to correspond with the shaping mechanism 7, so that when the hydraulic rod 2 drives the fixed plate 3 again... During descent, the fixed plate 3 and the support plate 4 press against each other to secure the rice cooker shell. The descent of the fixed plate 3 drives the drive component 63, increasing the pressure exerted by the abutment plate 62 on the inner wall of the rice cooker shell. Simultaneously, the shaping mechanism 7 operates automatically, positioned near the punching location on the rice cooker shell. This allows the shaping mechanism 7 to work with the abutment plate 62 to adjust the uneven areas of the rice cooker shell, ensuring that the shell's appearance does not significantly change after punching. This facilitates observation by staff to ensure the punching meets requirements. After shaping, the hydraulic rod 2 again lifts the fixed plate 3, which in turn drives the drive component 63. The drive component 63 causes the rotating cylinder 5 and the rice cooker shell to rotate in the opposite direction. As the fixed plate 3 resets, the abutment plate 62 releases its contact with the inner wall of the rice cooker shell, allowing staff to easily remove the punched rice cooker shell. The rotating cylinder 5 then resets to prepare for punching the next rice cooker shell.
[0033] The driving component 63 includes a piston plate 64 that is slidably connected to the inner wall of the fixed box 60. One end of the piston plate 64 is fixedly connected to the inner wall of the moving rod 61. A vent pipe 65 is fixedly connected to the end of the fixed box 60 away from the abutment plate 62. One end of the vent pipe 65 is connected to the fixed box 60, and the other end of the vent pipe 65 is connected to the bottom of the rotating cylinder 5. A connecting rod 66 is fixedly connected to the bottom of the fixed plate 3. A piston plate 67 is fixedly connected to one end of the connecting rod 66. The piston plate 67 can be slidably connected to the inner wall of the rotating cylinder 5.
[0034] When the fixed plate 3 descends, it drives the connecting rod 66 to descend. The connecting rod 66 drives the piston plate 67 to descend and slide into the inner wall of the rotating cylinder 5. When the piston plate 67 slides down along the inner wall of the rotating cylinder 5, it transports the air in the inner wall of the rotating cylinder 5 to the inner wall of the fixed box 60 through the vent pipe 65, thereby pushing the piston plate 64 to move. The piston plate 64 drives the moving rod 61 to move. The moving rod 61 drives the abutment plate 62 to approach the inner wall of the rice cooker shell and squeeze the inner wall of the rice cooker shell. When the punching machine body 1 punches the rice cooker shell, the abutment plate 62 can squeeze the area around the punching position of the rice cooker shell, thereby preventing the metal near the punching position of the rice cooker shell from bulging towards the rotating cylinder 5.
[0035] After the punching body 1 completes punching, the fixed plate 3 will drive the connecting rod 66 to rise a certain distance. The connecting rod 66 will then drive the piston plate 67 to slide upward along the inner wall of the rotating cylinder 5. The piston plate 67 sliding upward along the inner wall of the rotating cylinder 5 will reduce the pressure of the gas at the bottom of the fixed cylinder, thus reducing the squeezing force of the abutment plate 62 on the inner wall of the rice cooker. However, at this time, there is still a squeezing force between the abutment plate 62 and the outer shell of the rice cooker. Therefore, when the rotating part 69 drives the rotating cylinder 5 to rotate, the rotating cylinder 5 will drive the fixed box 60 to rotate. The fixed box 60 drives the moving rod 61 to rotate, and the moving rod 61 drives the abutment plate 62 to rotate. Since there is a squeezing between the abutment plate 62 and the outer shell of the rice cooker, and the fixed plate 3 no longer squeezes the top of the outer shell of the rice cooker, the abutment plate 62 can drive the outer shell of the rice cooker to rotate. This allows the punching position of the outer shell of the rice cooker to move to the position of the shaping mechanism 7. The abutment plate 62, together with the shaping mechanism 7, can perform secondary shaping on the punching position of the outer shell of the rice cooker, so that the appearance shape of the outer shell of the rice cooker will not change significantly after punching.
[0036] The inner wall of the rotating cylinder 5 is provided with a rotating component 69 capable of driving the rotating cylinder 5 to rotate. The rotating component 69 includes a drive plate 610 slidably connected to the inner wall of the rotating cylinder 5. A compression spring 611 is fixedly connected to the bottom of the drive plate 610. One end of the compression spring 611 is fixedly connected to the punch press body 1. A locking block 612 is fixedly connected to the end of the drive plate 610 away from the compression spring 611. The locking block 612 is polygonal in shape. The inner wall of the piston plate 67 is provided with a locking groove 613 that can engage with the locking block 612. The engagement of the locking block 612 with the locking groove 613 prevents the drive plate 610 from rotating. A rotating component 69 capable of driving the rotating cylinder 5 to rotate is fixedly connected to the outer side of the drive plate 610. The rubber block 614 of the rotating cylinder 5 can slide along the inner wall of the limiting groove 615 due to the elasticity of the rubber. The inner wall of the rotating cylinder 5 is provided with a limiting groove 615 that can slide with the rubber block 614. The limiting groove 615 is provided with two descending sections 616 and two ascending sections 617. One end of the ascending section 617 is connected to the bottom of the descending section 616, and the other end of the ascending section 617 is connected to the top of the remaining descending section 616. The depth of the descending section 616 increases from shallow to deep, and the depth of the ascending section 617 decreases from deep to shallow. The two ascending sections 617 intersect, so that the rubber block 614 can circulate within the limiting groove 615.
[0037] As piston plate 67 moves downward along the inner wall of rotating cylinder 5, locking block 612 slides into locking groove 613 at the bottom of piston plate 67. As piston plate 67 continues to move downward, it pushes drive plate 610 downward. At this time, piston plate 67 remains sealed to the inner wall of rotating cylinder 5. Drive plate 610 drives rubber block 614 from the upper end of the descending section 616 of limiting groove 615 to the lower end of the descending section 616. Drive plate 610 compresses spring 611. When fixed plate 3 rises, fixed plate 3 drives piston plate 67 to slide upward along the inner wall of rotating cylinder 5 via connecting rod 66. At this time, the compressed spring 611 pushes drive plate 610 upward. Because there is a discontinuity at the junction of the ascending section 617 and the descending section 616 of limiting groove 615, the drive plate 610... When the moving plate 610 pushes the rubber block 614 upward, the rubber block 614 can only slide along the rising section 617 of the limiting groove 615 and move to the top of another descending section 616. The rubber block 614 slides on the inner wall of the rising section 617. The squeezing of the rubber block 614 and the inner wall of the rising section 617 pushes the rotating cylinder 5 to rotate on the inner wall of the punch body 1, so that the punching position of the rice cooker shell can be moved to the position of the shaping mechanism 7. Then the hydraulic rod 2 pushes the fixed plate 3 downward again. The fixed plate drives the connecting rod 66 to move. The connecting rod 66 drives the piston plate 67 to move downward along the inner wall of the rotating cylinder 5. The piston plate 67 drives the drive plate 610 to move downward, and makes the rubber block 614 slide downward along the descending section 616 of the limiting groove 615 to cooperate in continuing to compress the air at the bottom of the rotating cylinder 5.
[0038] After the shaping mechanism 7, in conjunction with the abutment plate 62, completes the shaping of the rice cooker shell, the hydraulic rod 2 drives the fixed plate 3 to reset. The fixed plate 3, through the connecting rod 66, drives the piston plate 67 to slide upward and out of the inner wall of the rotating cylinder 5. The compression spring 611, which is in a compressed state, pushes the drive plate 610 to slide upward. The drive plate 610 drives the rubber block 614 to move upward along the rising section 617 of the limiting groove 615. Through the compression of the rubber block 614 and the inner wall of the rising section 617, the rotating cylinder 5 is pushed to rotate in the opposite direction to cooperate with the punching and shaping of the next rice cooker shell.
[0039] The shaping mechanism 7 includes multiple support seats 70 fixedly connected to the surface of the punch press body 1. The multiple support seats 70 correspond to the positions of the rotating abutment plate 62. A hydraulic push rod 71 is fixedly connected to one side of the support seat 70. A shaping plate 72 is fixedly connected to the output end of the hydraulic push rod 71. The curved surface of the shaping plate 72 is the same as the outer curved surface of the rice cooker shell. After the abutment plate 62 drives the rice cooker shell to rotate, the hydraulic push rod 71 automatically works to push the shaping plate 72 close to the rice cooker shell and cooperate with the abutment plate 62 to squeeze the rice cooker shell to flatten the uneven parts on the surface of the rice cooker shell. This ensures that the appearance shape of the rice cooker shell does not change significantly after punching, making it convenient for workers to observe whether the punching of the rice cooker shell meets the requirements, reducing the production process and improving the production efficiency of the rice cooker shell.
[0040] Example 2
[0041] like Figure 8-9 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the two ascending sections 617 are respectively provided with limiting members 8 at the intersection to prevent the rubber block 614 from sliding off track. The limiting member 8 includes a baffle 80 attached to the inner wall of the ascending section 617. The baffle 80 is made of elastic materials such as rubber and silicone. One end of the baffle 80 is fixedly connected to the inner wall of the ascending section 617. When the rubber block 614 slides on the inner wall of the ascending section 617 in the limiting groove 615, the rubber block 614 pushes the baffle 80 blocking the inner wall of the ascending section 617 to one side, so that the baffle 80 blocks the fork of the other ascending section 617, preventing the rubber block 614 from sliding off track. Since the baffle 80 is made of elastic materials such as rubber and silicone, the baffle 80 can be reset after the rubber block 614 passes through the baffle 80 to cooperate with the next cycle.
