Description

Technical Field

[0001] This invention belongs to the field of stamping processing, specifically a multi-station stamping and cutting equipment for intelligent door lock shells. Background Technology

[0002] Stamping is a metal forming process that uses a press and dies to apply external force to metal sheets and strips, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of specific shapes and sizes. This process is suitable for mass production and has advantages such as high production efficiency, high material utilization, good product consistency, and the ability to process complex shapes. Multi-station punching, on the other hand, is a processing method in which different punching processes are completed sequentially through multiple stations on a single punch press or production line.

[0003] Door lock housing punching is a blanking process in stamping, which uses special molds to separate or trim metal sheets to form mounting holes, slots and the outline of the housing.

[0004] Traditional multi-station stamping equipment often uses multiple stamping stations placed side by side, along with transfer equipment such as robotic arms, to control the workpieces to gradually pass through multiple stamping stations. The multiple workpieces placed side by side occupy a large area, and with the addition of complex transfer equipment, the cost is not only high, but the transfer equipment also has certain limitations when dealing with lightweight thin sheets or thick-cut heavy sheets, and it is difficult to perfectly adapt to the workpieces. In addition, if the high-precision transfer equipment fails, the stamping process can only be stopped and waited for, which affects the processing efficiency.

[0005] Therefore, the present invention provides a multi-station stamping and cutting equipment for intelligent door lock shells. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a multi-station stamping and cutting equipment for intelligent door lock shells, including an inclined stamping tunnel box, the stamping tunnel box being composed of multiple workstations, each workstation including a stamping cabinet that runs through the front and back, the stamping cabinet being provided with an upper template and a lower template that can be lifted and opened, the bottom inner side of the stamping cabinet being equipped with a deflector plate that can be rotated, and both the surface of the deflector plate and the inner side of the stamping cabinet being provided with adsorption components that can adsorb workpieces; This setup not only enables multi-station workpiece stamping but also shifts some of the original horizontal space to the air, improving space utilization. Furthermore, the workpiece transfer process eliminates the need for complex transport equipment, utilizing gravity and tilting sliding to ensure smooth transfer between multiple workstations. Because the workpiece remains in contact with the inner wall of the equipment throughout the process, it can handle both thin, lightweight and thick, heavy workpieces effectively. The simple structure reduces the likelihood of malfunctions, ensuring a long-term, orderly process. For thin, lightweight workpieces, the sliding motion against the inner wall during transfer prevents issues such as center settlement and transfer vibration that could affect positioning accuracy and processing quality. For thicker, heavy workpieces, high-powered lifting and transport equipment is unnecessary; the workpiece's own weight suffices for transport, reducing the difficulty of inter-station transport and ensuring finished product quality.

[0008] Preferably, both the upper and lower ends of the stamping cabinet are fixedly connected to vertically arranged recovery pipes. The upper and lower templates are respectively located in the upper and lower recovery pipes. The upper and lower templates can be completely removed from the recovery pipes. With the setting of the recovery pipes, when the workpiece slides, the upper and lower templates are respectively located in the recovery pipes. Due to the limitation of the recovery pipes, the upper and lower templates can be accurately matched. If necessary, suitable positioning parts can be added to the surface of the upper and lower templates. When it is necessary to replace the upper and lower templates, they are controlled to completely detach from the recovery pipes for replacement.

[0009] Preferably, a hydraulic platform is provided on the outside of the stamping tunnel box. Multiple synchronous rods are provided on the top and bottom of the hydraulic platforms. The synchronous rods are used to control the synchronous lifting and lowering of the upper and lower templates. The outside of the hydraulic platform also needs to be supported by support frames or other equipment, and the side of the hydraulic platform closest to the stamping tunnel box is fixed to the stamping tunnel box. The synchronous lifting and lowering is controlled by the hydraulic platform to ensure that the upper and lower templates of multiple workstations perform synchronous stamping work. The lifting amplitude needs to be adjusted according to different mold sizes, and the lifting distance of the upper and lower templates is also different.

[0010] Preferably, a transmission arm is fixedly connected to the outer side of both the upper and lower templates, and a connecting platform is fixedly connected to the end of the transmission arm. A synchronization platform is provided at both the upper and lower ends of the stamping tunnel box. Multiple locking platforms are installed on the side of the synchronization platform facing the stamping tunnel box. The locking platform is connected to the connecting platform. The locking platform can be separated from the connecting platform, and the connecting platform, transmission arm and mold can be directly removed to facilitate fine adjustment of the mold. Then the connecting platform is directly fixed to the locking platform to complete the installation.

[0011] Preferably, the inner bottom surface of the stamping tunnel box is provided with a flush groove for placing the deflector plate. The flush groove is located at the top of the lower recovery pipe. The top of the deflector plate is rotatably connected to the stamping tunnel box through a rotating shaft. Under normal conditions, the deflector plate is flush with the bottom wall of the stamping cabinet to ensure the smooth sliding process of the workpiece. When the workpiece is lifted by the lower template, it can rotate around the rotating shaft at the top of the deflector plate as the center, ensuring that it is in a horizontal state when it rotates to the final state, thereby performing the most accurate stamping work.

[0012] Preferably, the stamping tunnel box has pressing frames on both sides near the top. Each pressing frame includes a long strip and an embedded plate. The long strip is connected to the embedded plate, and the embedded plate is slidably engaged inside the stamping cabinet. The maximum processing size of the stamping tunnel box is a workpiece with a width equal to the inner width of the stamping tunnel box. When supporting the workpiece, raw materials of the same width can be used for stamping each time. In the first few stamping stages, the required punching requirements such as key holes can be processed first. In the final stamping stage, edge punching and cutting are performed to cut out the finished product of the required size. At this time, the finished product cannot be completely separated from the edge material, and some sprue needs to be left. The finished product and the edge material need to be discharged together from the bottom of the equipment. After cutting the sprue, the required finished product can be obtained. In the processing flow of the workpiece with the maximum processing size, the pressing frame is not required. When the width of the raw material workpiece is smaller than the maximum processing size, the pressing frame needs to be added. The two pressing frames need to be just engaged on both sides of the workpiece to ensure that the workpiece does not rotate during sliding. The long strip of the pressing frame is of various types to adapt to different workpieces.

[0013] Preferably, the adsorption component includes an adsorption block with ventilation holes around it. A negative pressure fan connected to the ventilation holes is fixed to the outside of the stamping cabinet. The workpiece is usually made of a metal material that can be magnetized and can be directly magnetically attracted using the adsorption block. The adsorption block has a built-in electromagnet module to generate a magnetic attraction effect. When the workpiece cannot be magnetized, a negative pressure fan is used to generate negative pressure for adsorption and fixation.

[0014] Preferably, the inside of the stamping cabinet is covered with a cover plate, the top surface of which has a through-hole extending to the bottom. The bottom inner side of the stamping cabinet has a connecting valve adapted to the cover plate. The surface of the cover plate is rotatably connected to a synchronous plate with the same structure as the deflection plate. When the workpiece is short and cannot directly cross the recovery pipe, or when the mold size is small and cannot adapt to the recovery pipe, a cover plate can be laid inside the stamping cabinet. The cover plate has a variety of through-hole sizes to accommodate various molds and workpieces, ensuring that the workpiece can be processed smoothly. The air pressure and circuit are connected through the connecting valve. An adsorption component is also installed on the lower part of the top surface of the cover plate to determine the position of the workpiece.

[0015] Preferably, the punching holes on the surface of the lower template extend to the top of the locking platform, and multiple exhaust vents are installed on the lower synchronous platform. The exhaust vents face the locking platform, and the debris generated by punching will fall onto the lower synchronous platform through the punching holes. The airflow is blown out through the exhaust vents to discharge the debris to all sides, ensuring the normal lifting and lowering of the lower template.

[0016] Preferably, a recycling component is installed on the inner side of the stamping cabinet near the top. The top of the recycling component is close to the recycling pipe located above. A pneumatic module is provided on the top of the recycling component. Some debris may remain on the surface of the workpiece. When the workpiece slides down, it will pass through the recycling component. The recycling component can be an elastic tube with a hollow center. It can intercept the debris on the surface of the workpiece when it passes through. At the same time, the pneumatic module above can provide negative pressure to the recycling component to absorb the debris, ensuring that the workpiece is not affected by debris during the processing of the equipment.

[0017] The beneficial effects of this invention are as follows: 1. The multi-station stamping and cutting equipment for intelligent door lock shells described in this invention, through the setting of an inclined stamping tunnel box, not only realizes the multi-station workpiece stamping function, but also transfers part of the original horizontal space to the air, improving space utilization. At the same time, the workpiece transfer process does not require complex transportation equipment. It utilizes the combination of gravity and inclined sliding to ensure the transfer of workpieces on multiple workstations. Since the workpiece is in contact with the inner wall of the equipment throughout the process, it can handle both thin and light workpieces and thick and heavy workpieces well. Moreover, the structure is simple, not prone to failure, and ensures the long-term and orderly operation of the process.

[0018] 2. The multi-station stamping and cutting equipment for intelligent door lock shells described in this invention, through the setting of a deflection plate, is flush with the bottom wall of the stamping cabinet in normal state, ensuring the smooth sliding process of the workpiece. When the workpiece is lifted by the lower template, the top of the workpiece is fixed on the deflection plate by the adsorption component, and the workpiece can rotate along the rotation axis at the top of the deflection plate as the center, ensuring that it is in a horizontal state when it rotates to the final state, thereby performing the most accurate stamping work.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 8 As shown in the figure, a multi-station stamping and cutting equipment for a smart door lock shell according to an embodiment of the present invention includes an inclined stamping tunnel box 1. The stamping tunnel box 1 is composed of multiple workstations 5. Each workstation 5 includes a stamping cabinet 6 that runs through the front and back. The stamping cabinet 6 is provided with an upper template 12 and a lower template 14 that can be lifted and opened. A deflection plate 13 that can be rotated is installed on the inner bottom of the stamping cabinet 6. The surface of the deflection plate 13 and the inner interior of the stamping cabinet 6 are provided with adsorption components that can adsorb workpieces. The door lock shell workpiece to be stamped is fed into the stamping tunnel box 1 from above. Initially, the workpiece is a flat metal sheet. The workpiece is placed against the inner bottom surface of the stamping tunnel box 1, and then released, allowing it to slide downwards under gravity. When it reaches the desired predetermined position, it is fixed by two suction components at the bottom and top of the workpiece. A simple sensing system can be used for positioning. For example, a sensor can be installed on the bottom suction component. When the workpiece covers the sensor, the bottom suction component activates, simultaneously activating the top suction component. This ensures accurate workpiece positioning with an error not exceeding millimeters. After fixation, the lower suction component is released, leaving only the upper suction component fixed (i.e., the suction component of the deflection plate 13 remains fixed). Then, the upper template 12 and lower template 14 are controlled to move towards the center. During the closing process, the workpiece is gradually pressed together. Because the top of the workpiece is fixed by the suction components... Furthermore, the deflection plate 13 can rotate, so the workpiece will rotate around the deflection plate 13 as the axis. The highest position that the lower template 14 can be raised to is exactly the height of the workpiece when the deflection plate 13 rotates to a horizontal position. With this setting, the workpiece can be smoothly deflected to a horizontal state under the support of the lower template 14. At the same time, the upper template 12 and the lower template 14 close together to perform the stamping process. After the stamping is completed, as the lower template 14 sinks, the workpiece returns to the state of being in contact with the bottom of the stamping tunnel box 1, releasing the adsorption of the adsorbent and allowing the workpiece to slide down under the action of gravity and enter the stamping cabinet 6 of the next workstation 5 for stamping work. At this time, a new workpiece can be put into the top for stamping work, and the stamping time of the previous workpiece will coincide with that of the previous workpiece, and the work will be carried out synchronously on different workstations 5. When the workpiece is discharged from the bottom of the stamping tunnel box 1, the workpiece has completed the stamping work of all workstations. The equipment can be placed using a support frame or other structure, fixed to the outside of the stamping tunnel box 1, so that it is kept in an inclined and suspended state. This setup not only enables multi-station workpiece stamping but also shifts the original horizontal footprint to the air, improving space utilization. Furthermore, the workpiece transfer process eliminates the need for complex transport equipment, utilizing gravity and tilting sliding to ensure smooth transfer across multiple workstations. Because the workpiece remains in contact with the equipment's inner wall throughout the process, it can handle both thin, lightweight and thick, heavy workpieces effectively. The simple structure reduces the risk of malfunctions, ensuring a long-term, orderly process. For thin, lightweight workpieces, the sliding motion against the inner wall during transfer prevents issues like center settlement or transfer vibration that could affect positioning accuracy and processing quality. For thicker, heavy workpieces, high-powered lifting and transport equipment is unnecessary; the workpiece's own weight suffices for transport, reducing the difficulty of inter-station transport and ensuring finished product quality.

[0023] The upper and lower ends of the stamping cabinet 6 are both fixed with vertically arranged recycling pipes 7. The upper template 12 and the lower template 14 are respectively located in the upper and lower recycling pipes 7. The upper template 12 and the lower template 14 can be completely removed from the recycling pipes 7. During operation, the upper template 12 and lower template 14 are located in the recycling pipe 7 when the workpiece slides, thanks to the setting of the recycling pipe 7. Due to the limitation of the recycling pipe 7, the upper template 12 and lower template 14 can be accurately matched. If necessary, suitable positioning parts can be added to the surface of the upper template 12 and lower template 14. When it is necessary to replace the upper template 12 and lower template 14, the two are controlled to completely detach from the recycling pipe 7 for replacement.

[0024] A hydraulic platform 3 is provided on the outside of the stamping tunnel box 1. Multiple synchronous rods 4 are provided on the top and bottom of the multiple hydraulic platforms 3. The synchronous rods 4 are used to control the upper template 12 and the lower template 14 to rise and fall synchronously. During operation, the outer side of the hydraulic table 3 also needs to be supported by support frames and other equipment, and the side of the hydraulic table 3 closest to the stamping tunnel box 1 is fixed to the stamping tunnel box 1; the hydraulic table 3 controls the synchronous rod 4 to lift and lower synchronously, thereby ensuring that the upper template 12 and lower template 14 of multiple workstations perform synchronous stamping work; the lifting amplitude needs to be adjusted according to different mold sizes, and the lifting distance of the upper template 12 and lower template 14 is also different.

[0025] The upper template 12 and the lower template 14 are both fixedly connected to the outer side of the transmission arm 8, and the end of the transmission arm 8 is fixedly connected to the connecting platform 9. The upper and lower ends of the stamping tunnel box 1 are both provided with a synchronous platform 2. Multiple locking platforms 22 are installed on the side of the synchronous platform 2 facing the stamping tunnel box 1. The locking platform 22 is connected to the connecting platform 9. During operation, the locking platform 22 can be separated from the connecting platform 9. The connecting platform 9, the transmission arm 8, and the mold can be removed directly to facilitate fine-tuning of the mold. Then, the connecting platform 9 can be directly fixed to the locking platform 22 to complete the installation.

[0026] The inner bottom surface of the stamping tunnel box 1 is provided with a flush groove for placing the deflection plate 13. The flush groove is located at the top of the lower recovery pipe 7. The top of the deflection plate 13 is rotatably connected to the stamping tunnel box 1 through a rotating shaft. During operation, the deflection plate 13 is flush with the bottom wall of the stamping cabinet 6 in its normal state, ensuring the smooth sliding process of the workpiece. When the workpiece is lifted by the lower template 14, it can rotate around the rotation axis at the top of the deflection plate 13, ensuring that it is in a horizontal state when it rotates to the final state, thus performing the most accurate stamping work.

[0027] The stamping tunnel box 1 has pressing frames 16 installed on both sides near the top inside. The pressing frame 16 includes a long strip plate and an embedded plate. The long strip plate is connected to the embedded plate, and the embedded plate is slidably engaged inside the stamping cabinet 6. During operation, the maximum processing size of the stamping tunnel box 1 is a workpiece with a width equal to the inner width of the stamping tunnel box 1. When supporting the workpiece, the same width of raw material can be used for stamping each time. In the first few stamping stages, the required punching requirements such as lock holes can be processed first. In the final stamping stage, edge punching and cutting are performed to cut out the finished product of the required size. At this time, the finished product cannot be completely separated from the edge material, and some sprue needs to be left. The finished product and the edge material need to be discharged from the bottom of the equipment together. After cutting the sprue, the required finished product can be obtained. In the processing flow of the workpiece with the maximum processing size, the pressing frame 16 is not required. When the width of the raw material workpiece is smaller than the maximum processing size, the pressing frame 16 needs to be added. The two pressing frames 16 need to be just stuck on both sides of the workpiece to ensure that the workpiece does not rotate when sliding. The long strips of the pressing frame 16 are of various types to adapt to different workpieces.

[0028] The adsorption component includes an adsorption block 24, and ventilation holes are provided around the adsorption block 24. A negative pressure fan 11 connected to the ventilation holes is fixed to the outside of the stamping cabinet 6. During operation, the workpiece is usually made of non-magnetizable metal material and can be directly attracted by magnetic attraction using the adsorption block 24. The adsorption block 24 has a built-in electromagnet module to generate magnetic attraction. When the workpiece cannot be magnetized, the negative pressure fan 11 is used to generate negative pressure for adsorption and fixation.

[0029] The inside of the stamping cabinet 6 is covered with a cover plate 17. The top surface of the cover plate 17 has a through hole 19 extending to the bottom. The bottom inner side of the stamping cabinet 6 has a connecting valve 23 adapted to the cover plate 17. The surface of the cover plate 17 is rotatably connected to a synchronization plate 18 with the same structure as the deflection plate 13. During operation, when the workpiece is too short to directly cross the recycling pipe 7, or when the mold size is too small to fit the recycling pipe 7, a cover plate 17 can be laid inside the stamping cabinet 6. The cover plate 17 has many through holes 19 of various sizes to accommodate different molds and workpieces, ensuring that the workpiece can be processed smoothly. The air pressure and circuit are connected through the connecting valve 23. The top surface of the cover plate 17 is also equipped with an adsorption component to determine the position of the workpiece.

[0030] The punching holes 20 on the surface of the lower template 14 extend to the top of the locking platform 22. Multiple exhaust ports 21 are installed on the synchronization platform 2 located below, and the exhaust ports 21 face the locking platform 22. During operation, the debris generated by stamping will fall onto the synchronous table 2 below through the stamping hole 20, and the airflow will blow out through the exhaust port 21 to discharge the debris to all sides, ensuring that the lower template 14 can rise and fall normally.

[0031] A recycling component 15 is installed on the inner side of the stamping cabinet 6 near the top. The top of the recycling component 15 is close to the recycling pipe 7 located above it, and a pneumatic module is provided on the top of the recycling component 15. During operation, some debris may remain on the surface of the workpiece. As the workpiece slides down, it passes through the recovery component 15, which can be a hollow elastic tube in the center. This component can trap the debris on the surface of the workpiece as it passes through. At the same time, the air pressure module above can provide negative pressure to the recovery component 15 to absorb the debris, ensuring that the workpiece is not affected by debris during processing.

[0032] During operation, the door lock shell workpiece to be stamped is fed into the stamping tunnel box 1 from above. Initially, the workpiece is a flat metal sheet. The workpiece is placed against the inner bottom surface of the stamping tunnel box 1, and then released, allowing it to slide downwards under gravity. When it reaches the desired predetermined position, it is fixed by two suction components at the bottom and top of the workpiece. A simple sensing system can be used for positioning. For example, a sensor can be installed on the bottom suction component. When the workpiece covers the sensor, the bottom suction component activates, simultaneously activating the top suction component. This ensures accurate workpiece positioning with an error not exceeding millimeters. After fixation, the lower suction component is released, leaving only the upper suction component fixed (i.e., the suction component of the deflection plate 13 remains fixed). Then, the upper template 12 and lower template 14 are controlled to move towards the center. During this closing process, the workpiece is gradually pressed together. Because the top of the workpiece is held in place by the suction components... The workpiece is fixed and the deflection plate 13 can rotate, so the workpiece will rotate around the deflection plate 13 as the axis. The highest position that the lower template 14 can be raised is exactly the height of the workpiece when the deflection plate 13 rotates to the horizontal position. With this setting, the workpiece can be smoothly deflected to the horizontal position under the support of the lower template 14. At the same time, the upper template 12 and the lower template 14 close together to perform the stamping process. After the stamping is completed, as the lower template 14 sinks, the workpiece returns to the state of being in contact with the bottom of the stamping tunnel box 1, releasing the adsorption of the adsorbent and allowing the workpiece to slide down under the action of gravity and enter the stamping cabinet 6 of the next workstation 5 for stamping. At this time, a new workpiece can be put into the top for stamping, and the stamping time of the previous workpiece will coincide with that of the previous workpiece, and the stamping will be carried out synchronously on different workstations 5. When the workpiece is discharged from the bottom of the stamping tunnel box 1, the workpiece has completed the stamping work of all workstations. The equipment can be placed using a support frame or other structure, fixed to the outside of the stamping tunnel box 1, so that it is kept in an inclined and suspended state. This setup not only enables multi-station workpiece stamping but also shifts the original horizontal footprint to the air, improving space utilization. Furthermore, the workpiece transfer process eliminates the need for complex transport equipment, utilizing gravity and tilting sliding to ensure smooth transfer across multiple workstations. Because the workpiece remains in contact with the equipment's inner wall throughout the process, it can handle both thin, lightweight and thick, heavy workpieces effectively. The simple structure reduces the risk of malfunctions, ensuring a long-term, orderly process. For thin, lightweight workpieces, the sliding motion against the inner wall during transfer prevents issues like center settlement or transfer vibration that could affect positioning accuracy and processing quality. For thicker, heavy workpieces, high-powered lifting and transport equipment is unnecessary; the workpiece's own weight suffices for transport, reducing the difficulty of inter-station transport and ensuring finished product quality.

[0033] With the setting of the recovery tube 7, when the workpiece slides, the upper template 12 and the lower template 14 are respectively located in the recovery tube 7. Due to the limitation of the recovery tube 7, the upper template 12 and the lower template 14 can be accurately matched. If necessary, suitable positioning parts can be added to the surface of the upper template 12 and the lower template 14. When it is necessary to replace the upper template 12 and the lower template 14, control both to completely detach from the recovery tube 7 for replacement.

[0034] The outside of the hydraulic table 3 also needs to be supported by support frames and other equipment, and the side of the hydraulic table 3 closest to the stamping tunnel box 1 is fixed to the stamping tunnel box 1; the hydraulic table 3 controls the synchronous rod 4 to lift and lower synchronously, thereby ensuring that the upper template 12 and lower template 14 of multiple workstations can perform synchronous stamping work; the lifting amplitude needs to be adjusted according to different mold sizes, and the lifting distance of the upper template 12 and lower template 14 is also different.

[0035] The locking platform 22 can be separated from the connecting platform 9. The connecting platform 9, the transmission arm 8 and the mold can be removed directly to facilitate fine-tuning of the mold. Then, the connecting platform 9 can be directly fixed to the locking platform 22 to complete the installation.

[0036] In normal conditions, the deflection plate 13 is flush with the bottom wall of the stamping cabinet 6, ensuring the smooth sliding process of the workpiece. When the workpiece is lifted by the lower template 14, it can rotate around the rotation axis at the top of the deflection plate 13, ensuring that it is in a horizontal state when it rotates to the final state, thus performing the most accurate stamping work.

[0037] The maximum processing size of the stamping tunnel box 1 is: a workpiece with a width equal to the inner width of the stamping tunnel box 1. When supporting the workpiece, the same width of raw material can be used for stamping each time. In the first few stamping stages, the required punching requirements such as lock holes can be processed first. In the final stamping stage, edge punching and cutting are performed to cut out the finished product of the required size. At this time, the finished product cannot be completely separated from the edge material, and some sprue needs to be left. The finished product and the edge material need to be discharged from the bottom of the equipment together. After cutting the sprue, the required finished product can be obtained. In the processing flow of the workpiece with the maximum processing size, the pressing frame 16 is not required. When the width of the raw material workpiece is smaller than the maximum processing size, the pressing frame 16 needs to be added. The two pressing frames 16 need to be just stuck on both sides of the workpiece to ensure that the workpiece does not rotate when sliding. The long strips of the pressing frame 16 are of various types to adapt to different workpieces.

[0038] The workpiece is usually made of non-magnetizable metal material and can be directly attracted by magnetic attraction using adsorption block 24. Adsorption block 24 has a built-in electromagnet module to generate magnetic attraction. When the workpiece cannot be magnetized, negative pressure is generated by negative pressure fan 11 to attract and fix it.

[0039] When the workpiece is too short to directly cross the recycling pipe 7, or when the mold size is too small to fit the recycling pipe 7, a cover plate 17 can be laid inside the stamping cabinet 6. The cover plate 17 has many through holes 19 of various sizes to accommodate different molds and workpieces, ensuring that the workpiece can be processed smoothly. The air pressure and circuit are connected through the connecting valve 23. The top surface of the cover plate 17 is also equipped with an adsorption component to determine the position of the workpiece.

[0040] The debris generated during stamping will fall onto the synchronous table 2 below through the stamping hole 20, and will be blown outward through the exhaust port 21 to discharge the debris to all sides, ensuring that the lower template 14 can rise and fall normally.

[0041] Some debris may remain on the surface of the workpiece. When the workpiece slides down, it will pass through the recovery component 15. The recovery component 15 can be an elastic tube with a hollow center. It can trap the debris on the surface of the workpiece when it passes through. At the same time, the air pressure module above can provide negative pressure to the recovery component 15 to absorb the debris and ensure that the workpiece is not affected by the debris during the processing of the equipment.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
