Description

Technical Field

[0001] This invention relates to the field of metal stamping technology, specifically to a stamping die for producing aluminum foil lunch boxes. Background Technology

[0002] With the development of the disposable tableware industry, aluminum foil lunch boxes, as a lightweight and practical disposable tableware, are widely used in various occasions, such as airplanes, high-speed trains, hospitals, and cruise ships, due to their high temperature resistance, oil resistance, salt resistance, and good flavor retention. During the production of aluminum foil lunch boxes, stamping dies are used for stamping operations. Aluminum foil is a metal product, and its core component is metallic aluminum. Essentially, it is an ultra-thin metal sheet made of aluminum through rolling. The stamping machine tool used for aluminum foil lunch box production is a type of metal forming machine tool. The stamping die assembly is a major component of the stamping machine tool, consisting of a worktable, fixed die, moving die, and guide support assembly. The guide support assembly mainly consists of guide supports, guide sleeves, and guide sleeves.

[0003] However, existing stamping dies for aluminum foil food box production are not convenient for testing and sorting the sealing performance of the stamped aluminum foil food boxes, which affects the stamping quality.

[0004] Therefore, we propose a stamping die for the production of aluminum foil lunch boxes. Summary of the Invention

[0005] The purpose of this invention is to provide a stamping die for the production of aluminum foil lunch boxes, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stamping die for producing aluminum foil lunch boxes, comprising a guide pillar assembly, a fixed die, and a moving die arranged on a die assembly, wherein the guide pillar assembly comprises a guide pillar, a guide sleeve, and a return spring, and the top of the moving die is provided with a first detection mechanism for detecting the sealing performance of the stamped aluminum foil lunch box; The first detection mechanism includes an air pipe fixedly inserted into the top of the moving mold, and a first solenoid valve is fixedly connected to the upper end of the air pipe. A fan is fixedly connected to the upper end of the first solenoid valve. A moving ring is connected to the side wall of the moving mold through a moving mechanism. An air vent is fixedly inserted into the moving ring. A pressure sensor is provided on the side wall of the air pipe.

[0007] Preferably, the moving mechanism includes an L-shaped plate fixedly connected to the side wall of the moving mold, and two moving rods are inserted into the side wall of the L-shaped plate. A telescopic spring is sleeved on the side wall of each moving rod. One end of each moving rod is fixedly connected to a moving frame, and a moving ring is inserted into the moving frame. The moving ring is connected to the bottom of the moving frame through a lifting mechanism. The other end of each moving rod is fixedly connected to a moving block, and the movement of the moving block is driven by a pushing mechanism.

[0008] By adopting the above technical solution, the moving block is moved by the driving mechanism, which in turn drives the moving frame, moving ring and ventilation network to move synchronously.

[0009] Preferably, the pushing mechanism includes a pushing block, and the pushing block is connected to the moving block through a telescopic mechanism. The guide pillar has a support frame fixedly connected to its side wall, and a second pushing plate is fixedly connected to the upper end of the support frame. The bottom of the second pushing plate is provided with a second inclined surface, and the pushing block can slide on the second inclined surface.

[0010] By adopting the above technical solution, when the pushing block abuts against the second inclined surface, it can push the pushing block to move closer to the L-shaped plate. At the same time, the telescopic mechanism drives the moving block and the moving rod to move.

[0011] Preferably, the lifting mechanism includes an L-shaped block fixedly connected to the bottom of the moving ring, and the L-shaped block is connected to the bottom of the moving frame through a telescopic component. The bottom of the pushing block is fixedly connected to a first pushing plate, and the side wall of the first pushing plate is provided with a first inclined surface. The L-shaped block can slide on the first inclined surface.

[0012] By adopting the above technical solution, when the push block continues to move, it drives the first push plate to continue to move, so that the first inclined surface can abut against the side wall of the L-shaped block, thereby pushing the moving ring and the ventilation net to move upward, so that the moving ring abuts against the flange of the lunch box and presses it against the bottom of the moving mold. At this time, a sealed space can be formed between the lunch box and the moving mold.

[0013] Preferably, the telescopic assembly includes two first sleeve rods fixedly connected to the top of the L-shaped block. The side walls of the first sleeve rods are fitted with first sleeves, and the upper ends of the first sleeves are fixed to the bottom of the L-shaped plate. The side walls of each first sleeve are fitted with first springs.

[0014] By adopting the above technical solution, the first spring is compressed when the L-shaped block, the moving ring, and the ventilation net move upward.

[0015] Preferably, the telescopic mechanism includes two second sleeves fixedly connected to the side wall of the moving block, and a second sleeve rod is inserted into the second sleeve. The other end of the second sleeve rod is fixedly connected to a push block, and a second spring is sleeved on the side wall of each second sleeve.

[0016] By adopting the above technical solution, when the moving ring moves to the bottom of the lunch box, the telescopic spring can no longer be compressed. At this time, when the pushing block continues to move, the second spring can be compressed.

[0017] Preferably, the upper end of the guide pillar is provided with a lubrication mechanism for lubricating the inner wall of the guide sleeve. The lubrication mechanism includes an annular tube fixedly connected to the top of the guide pillar, and the side wall of the annular tube is provided with multiple oil outlet holes. The top of the guide pillar is provided with an oil supply assembly, which is used to supply grease into the annular tube.

[0018] By adopting the above technical solution, when the moving die is raised and lowered during stamping, it can drive the guide sleeve to slide on the side wall of the guide pillar. Lubricating grease is supplied into the annular tube through the oil supply component and applied to the inner wall of the guide sleeve through the oil outlet, thereby facilitating the lubrication of the guide sleeve and the guide pillar and ensuring its guiding effect.

[0019] Preferably, the oil supply assembly includes a support plate fixedly connected to the top of the guide pillar, and an oil storage tank is fixedly connected to the top of the support plate. A gravity block is slidably connected inside the oil storage tank. The oil storage tank is connected to an annular pipe through an L-shaped pipe, and a second solenoid valve is provided on the side wall of the L-shaped pipe.

[0020] By adopting the above technical solution, the second solenoid valve is opened, and under the gravity of the gravity block, the grease in the oil reservoir can be squeezed and enter the annular pipe through the L-shaped pipe.

[0021] Preferably, a second detection mechanism is provided at the upper end of the guide pillar, and the second detection mechanism is used to detect the gap between the guide pillar and the guide sleeve. The second detection mechanism includes multiple mounting brackets, and the side walls of each mounting bracket are rotatably connected to rollers via a rotating shaft. The mounting bracket is connected to the top of the guide pillar via a moving component. A roughness sensor can be installed on the mounting bracket to detect the roughness of the inner wall of the guide sleeve and is electrically connected to a second solenoid valve. When the roughness sensor detects that the roughness of the inner wall of the guide sleeve is large, the second solenoid valve is opened.

[0022] By adopting the above technical solution, when the moving mold performs the lifting mechanism, it can drive the guide sleeve to slide on the side wall of the guide pillar. At the same time, under the action of the moving component, the roller abuts against the inner wall of the guide sleeve. When the inner wall of the guide sleeve is worn, the gap between the guide sleeve and the guide pillar will increase. Under the action of the moving component, the mounting bracket and the roller move away from the connecting plate, ensuring that the roller and the inner wall of the guide sleeve remain abutted, which can play a certain guiding effect.

[0023] Preferably, the movable component includes two fifth sleeve rods fixedly connected to the side walls of each mounting bracket, and a fifth sleeve is fitted on the side wall of each fifth sleeve rod. The fifth sleeve is fixed to the top of the guide pillar through a connecting plate. A sixth spring is fitted on the side wall of each fifth sleeve, and a second distance sensor is fixedly inserted into the side wall of the connecting plate.

[0024] By adopting the above technical solution, under the action of the sixth spring, the roller abuts against the inner wall of the guide sleeve. When the inner wall of the guide sleeve is worn, the gap between the guide sleeve and the guide support will increase. Under the action of the sixth spring, the mounting bracket and the roller move away from the connecting plate, ensuring that the roller abuts against the inner wall of the guide sleeve. Furthermore, the movement stroke of the mounting bracket can be detected by the second distance sensor, thereby determining the degree of wear of the inner wall of the guide sleeve. This facilitates the detection of the gap between the guide sleeve and the guide support, ensuring the guiding effect and thus guaranteeing the stamping quality.

[0025] In summary, Advantage 1: It facilitates the inspection and sorting of the sealing of lunch boxes, ensuring the quality of stamping; Advantage 2: When the inner wall of the guide sleeve is not smooth enough, grease can be automatically applied to the inner wall of the guide sleeve, which facilitates automatic lubrication of the guide sleeve and guide support, ensuring its guiding effect, while avoiding the waste of lubricating oil, thereby ensuring the stamping quality; Advantage 3: It facilitates the detection of the gap between the guide sleeve and the guide support, ensuring the guiding effect and thus guaranteeing the stamping quality.

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.

[0029] Example 1 Please see Figures 1-7 The figure shows a stamping die for producing aluminum foil lunch boxes, including a guide pillar assembly 1101, a fixed die 1102, and a moving die 1103 mounted on the die assembly. The guide pillar assembly 1101 includes a guide pillar 1104, a guide sleeve 1105, and a return spring 1106. The fixed die 1102 is fixed on the machine tool's worktable, and the moving die 1103 is mounted on the machine tool's slider. The guide pillar assembly 1101 is located between the moving die 1103 and the worktable. These are all well-known technologies in this field and will not be described in detail here. The connecting parts of the guide pillar 1104 and the guide sleeve 1105 are detachably connected by a flange, and wiring can be routed from the top of the guide sleeve 1105 to ensure normal power supply to the first solenoid valve 1202, etc. The top of the moving die 1103 is provided with a first detection mechanism for detecting the sealing performance of the stamped aluminum foil lunch box. The first detection mechanism includes an air pipe 1201 fixedly inserted into the top of the moving mold 1103, with a first solenoid valve 1202 fixedly connected to the upper end of the air pipe 1201, and a fan 1203 fixedly connected to the upper end of the first solenoid valve 1202. A moving ring 1206 is connected to the side wall of the moving mold 1103 via a moving mechanism, and a ventilation net 1207 is fixedly inserted inside the moving ring 1206. A pressure sensor 1204 is provided on the side wall of the air pipe 1201. After stamping, this mechanism facilitates the detection and sorting of the sealing performance of the lunch box, ensuring the quality of stamping. It also facilitates the automatic application of grease to the inner wall of the guide sleeve 1105, thereby facilitating the automatic lubrication of the guide sleeve 1105 and the guide support 1104. At the same time, it facilitates the detection of the gap between the guide sleeve 1105 and the guide support 1104, ensuring the guiding effect and thus ensuring the quality of stamping.

[0030] The moving mechanism includes an L-shaped plate 401 fixedly connected to the side wall of the moving mold 1103, and two moving rods 402 are inserted into the side wall of the L-shaped plate 401. A telescopic spring 403 is sleeved on the side wall of the moving rod 402. One end of the moving rod 402 is fixedly connected to a moving frame 1205, and a moving ring 1206 is inserted into the moving frame 1205. The moving ring 1206 is connected to the bottom of the moving frame 1205 through a lifting mechanism. The other end of the moving rod 402 is fixedly connected to a moving block 404. The movement of the moving block 404 is driven by a pushing mechanism. The pushing mechanism drives the moving block 404 to move, and drives the moving frame 1205, the moving ring 1206 and the ventilation net 1207 to move synchronously.

[0031] The pushing mechanism includes a pushing block 412, which is connected to a moving block 404 via a telescopic mechanism. The guide pillar 1104 has a support frame 501 fixedly connected to its side wall, and a second pushing plate 502 is fixedly connected to the upper end of the support frame 501. A second inclined surface 503 is provided at the bottom of the second pushing plate 502, and the pushing block 412 can slide on the second inclined surface 503. When the pushing block 412 abuts against the second inclined surface 503, it can push the pushing block 412 to move towards the L-shaped plate 401. At the same time, the telescopic mechanism drives the moving block 404 and the moving rod 402 to move.

[0032] The lifting mechanism includes an L-shaped block 408 fixedly connected to the bottom of the moving ring 1206, and the L-shaped block 408 is connected to the bottom of the moving frame 1205 through a telescopic component. The bottom of the pushing block 412 is fixedly connected to a first pushing plate 413, and the side wall of the first pushing plate 413 is provided with a first inclined surface 414. The L-shaped block 408 can slide on the first inclined surface 414. When the pushing block 412 continues to move, it drives the first pushing plate 413 to continue to move, so that the first inclined surface 414 can abut against the side wall of the L-shaped block 408, thereby pushing the moving ring 1206 and the ventilation net 1207 to move upward, so that the moving ring 1206 abuts against the flange of the lunch box and presses it against the bottom of the moving mold 1103. At this time, a sealed space can be formed between the lunch box and the moving mold 1103.

[0033] The telescopic assembly includes two first sleeve rods 406 fixedly connected to the top of the L-shaped block 408. The side walls of the first sleeve rods 406 are fitted with first sleeves 405, and the upper end of the first sleeves 405 is fixed to the bottom of the L-shaped plate 401. The side walls of each first sleeve 405 are fitted with first springs 407. When the L-shaped block 408, the moving ring 1206 and the ventilation net 1207 move upward, the first springs 407 are compressed.

[0034] The telescopic mechanism includes two second sleeves 409 fixedly connected to the side wall of the moving block 404, and a second sleeve rod 410 is inserted into the second sleeve 409. A push block 412 is fixedly connected to the other end of the second sleeve rod 410, and a second spring 411 is sleeved on the side wall of each second sleeve 409.

[0035] The upper end of the guide pillar 1104 is provided with a lubrication mechanism for lubricating the inner wall of the guide sleeve 1105. To solve the technical problem of inconvenience in automatically lubricating the guide pillar and the guide sleeve during stamping, the lubrication mechanism includes an annular tube 201 fixedly connected to the top of the guide pillar 1104, and the side wall of the annular tube 201 is provided with multiple oil outlet holes 202. The top of the guide pillar 1104 is provided with an oil supply assembly, which is used to supply grease into the annular tube 201. During stamping, when the moving die 1103 moves up and down, it can drive the guide sleeve 1105 to slide on the side wall of the guide pillar 1104. The grease is supplied into the annular tube 201 through the oil supply assembly and applied to the inner wall of the guide sleeve 1105 through the oil outlet holes 202, thereby facilitating the lubrication of the guide sleeve 1105 and the guide pillar 1104 and ensuring their guiding effect.

[0036] The oil supply assembly includes a support plate 207 fixedly connected to the top of the guide pillar 1104, and an oil reservoir 204 fixedly connected to the top of the support plate 207. A gravity block 206 is slidably connected inside the oil reservoir 204. The oil reservoir 204 is connected to the annular pipe 201 through an L-shaped pipe 203. A second solenoid valve 205 is provided on the side wall of the L-shaped pipe 203. When the second solenoid valve 205 is opened, the grease in the oil reservoir 204 can be squeezed under the gravity of the gravity block 206 and enter the annular pipe 201 through the L-shaped pipe 203.

[0037] A second detection mechanism is provided at the upper end of the guide pillar 1104. This second detection mechanism is used to detect the gap between the guide pillar 1104 and the guide sleeve 1105. To solve the technical problem that it is inconvenient to detect the gap between the guide pillar and the guide sleeve during stamping, which affects the guiding effect, the second detection mechanism includes multiple mounting brackets 701. The sidewalls of each mounting bracket 701 are rotatably connected to rollers 703 via rotating shafts 702. The mounting brackets 701 are connected to the top of the guide pillar 1104 via a moving assembly. A roughness sensor can be installed on the mounting bracket 701 to detect the roughness of the inner wall of the guide sleeve 1105 and is electrically connected to the second solenoid valve 205. When the roughness sensor detects that the roughness of the inner wall of the guide sleeve 1105 is large, the second solenoid valve 205 is opened. When the moving mold 1103 performs the lifting mechanism, it can drive the guide sleeve 1105 to slide on the side wall of the guide pillar 1104. At the same time, under the action of the moving component, the roller 703 abuts against the inner wall of the guide sleeve 1105. When the inner wall of the guide sleeve 1105 is worn, the gap between the guide sleeve 1105 and the guide pillar 1104 will increase. Under the action of the moving component, the mounting bracket 701 and the roller 703 move away from the connecting plate 301 to ensure that the roller 703 abuts against the inner wall of the guide sleeve 1105, which can play a certain guiding effect.

[0038] The moving component includes two fifth sleeve rods 303 fixedly connected to the side walls of each mounting bracket 701, and a fifth sleeve tube 302 is sleeved on the side wall of each fifth sleeve rod 303. The fifth sleeve tube 302 is fixed to the top of the guide pillar 1104 via a connecting plate 301. A sixth spring 304 is sleeved on the side wall of each fifth sleeve tube 302, and a second distance sensor 305 is fixedly inserted into the side wall of the connecting plate 301. Under the action of the sixth spring 304, the roller 703 abuts against the inner wall of the guide sleeve 1105. When the inner wall of the guide sleeve 1105 is worn, the guide sleeve... The gap between 1105 and guide post 1104 will increase. Under the action of the sixth spring 304, the mounting bracket 701 and roller 703 will move away from the connecting plate 301, ensuring that the roller 703 keeps abutting against the inner wall of the guide sleeve 1105. Furthermore, the movement stroke of the mounting bracket 701 can be detected by the second distance sensor 305, which can determine the wear degree of the inner wall of the guide sleeve 1105. This facilitates the detection of the gap between the guide sleeve 1105 and guide post 1104, ensuring its guiding effect and thus ensuring the stamping quality.

[0039] Working principle: During use, the aluminum foil is conveyed and slides on the worktable. The moving mold 1103 is driven downward by the metal stamping equipment to stamp the aluminum foil into a lunch box. After stamping, the moving mold 1103 is driven upward by the stamping equipment. At the same time, the first solenoid valve 1202 is opened and the fan 1203 is started to perform a ventilation operation inside the moving mold 1103, which can attract the lunch box and make it move upward synchronously with the moving mold 1103. The moving frame 1205 and the moving ring 1206 are driven upward by the L-shaped plate 401.

[0040] When the pushing block 412 abuts against the second inclined surface 503, it can push the pushing block 412 to move closer to the L-shaped plate 401. At the same time, the second spring 411 pushes the moving block 404 and the moving rod 402 to move. The telescopic spring 403 is compressed, which drives the moving frame 1205, the moving ring 1206 and the ventilation net 1207 to move synchronously, and drives the first pushing plate 413 to move synchronously. When the moving ring 1206 moves to the bottom of the lunch box, the telescopic spring 403 can no longer be compressed. At this time, when the push block 412 continues to move, the second spring 411 is compressed, which drives the first push plate 413 to continue to move, so that the first inclined surface 414 can abut against the side wall of the L-shaped block 408, thereby pushing the moving ring 1206 and the ventilation net 1207 to move upward. At the same time, the first spring 407 is compressed, so that the moving ring 1206 abuts against the flange of the lunch box and presses it against the bottom of the moving mold 1103. At this time, a sealed space is formed between the lunch box and the moving mold 1103.

[0041] Next, the fan 1203 continues to draw air, creating negative pressure in the sealed space. The first solenoid valve 1202 and the fan 1203 are then closed. The change in gas pressure is observed by the pressure sensor 1204, which allows the sealing performance of the sealed space to be tested, and thus the sealing performance of the lunch box can be tested, making the process more convenient and faster.

[0042] When pressure sensor 1204 detects that the pressure in the sealed space has not increased, it indicates that the lunchbox's sealing performance is up to standard. At this time, the moving mold 1103 is moved downward by the stamping equipment, allowing the moving ring 1206 and the ventilation net 1207 to move and reset. Then, the first solenoid valve 1202 and the fan 1203 are opened, and the fan 1203 supplies air to the sealed space, allowing the lunchbox to fall normally. When pressure sensor 1204 detects that the pressure in the sealed space has increased, it indicates that the lunchbox's sealing performance is up to standard. If the food is found to be substandard, the first solenoid valve 1202 and the fan 1203 are opened to supply air into the sealed space, allowing the food container to fall onto the moving ring 1206 and the ventilation net 1207. Then, the stamping equipment drives the moving mold 1103 to move downward, allowing the moving ring 1206 and the ventilation net 1207 to move and reset. Finally, the substandard food container can be removed from the moving ring 1206 and the ventilation net 1207, thus facilitating the detection and sorting of the food container's sealing performance and ensuring the efficiency and quality of the stamping process.

[0043] During stamping, when the moving die 1103 operates the lifting mechanism, it can drive the guide sleeve 1105 to slide on the side wall of the guide pillar 1104. At the same time, under the action of the sixth spring 304, the roller 703 abuts against the inner wall of the guide sleeve 1105. When the roughness sensor detects that the inner wall of the guide sleeve 1105 is not smooth enough, the second solenoid valve 205 is opened. Under the gravity of the gravity block 206, the grease in the oil tank 204 is squeezed and enters the annular tube 201 through the L-shaped tube 203. It is then applied to the inner wall of the guide sleeve 1105 through the oil outlet 202, which facilitates automatic lubrication of the guide sleeve 1105 and the guide pillar 1104, ensuring their guiding effect and avoiding the waste of lubricating oil, thereby ensuring the stamping quality.

[0044] When the inner wall of the guide sleeve 1105 wears, the gap between the guide sleeve 1105 and the guide pillar 1104 will increase. Under the action of the sixth spring 304, the mounting bracket 701 and the roller 703 will move away from the connecting plate 301, ensuring that the roller 703 and the inner wall of the guide sleeve 1105 remain in contact, which can play a certain guiding role. Furthermore, the degree of wear of the inner wall of the guide sleeve 1105 can be determined by detecting the movement stroke of the mounting bracket 701 through the second distance sensor 305. This facilitates the detection of the gap between the guide sleeve 1105 and the guide pillar 1104, ensuring the guiding effect and thus ensuring the stamping quality.
