Description

Technical Field

[0001] This invention relates to the field of metal sheet cutting device technology, specifically a metal sheet cutting device for the production of daily-use metal products. Background Technology

[0002] Metal sheet cutting equipment cuts metal sheets into specific sizes through mechanical cutting, making it easier to assemble them into metal products.

[0003] Patent publication number CN216097466U relates to a quantitative cutting and pressing device for metal sheets, including a quantitative feeding mechanism, a cutting mechanism, and a bending mechanism. The quantitative feeding mechanism includes a quantitative guide rail with a movable clamping block on it and a fixed clamping block at its rear end. The cutting mechanism includes a guide block with a guide groove aligned with the channel of the fixed clamping block. A cutting table is located at the rear end of the guide block, and a cutting blade driven by a cutting cylinder is positioned above the cutting table. The bending mechanism includes a support plate with its upper edge flush with the cutting table, and a bending block driven by a bending cylinder is positioned above the support plate. The movable and fixed clamping blocks of the quantitative feeding mechanism cooperate to quantitatively feed the metal sheet. The cutting mechanism cuts the metal sheet, ensuring that the metal sheet at the bending mechanism is of a fixed length. Finally, the bending mechanism presses down to bend the long strip of metal sheet into a U-shape. The overall design is compact and suitable for automated production lines.

[0004] In the aforementioned patent, quantitative feeding is achieved through the cooperation of the moving and fixed clamping blocks of the quantitative feeding mechanism. The metal sheet is then cut by the cutting mechanism, ensuring that the metal sheet at the bending mechanism is of a fixed length. Finally, the bending mechanism presses down to bend the long strip of metal sheet into a U-shape. The overall connection and cooperation are compact, making it suitable for automated production lines. This effectively improves the processing efficiency and quality of stators and reduces production costs. However, during the cutting process, the surface of the metal sheet will warp due to the pressure of the cutting device, causing the metal sheet to bend and deform at the cutting point, resulting in uneven cutting and an uneven cut surface. Burrs are also easily left after cutting. After cutting, the metal sheets need to be manually stacked neatly, which is inefficient. Metal debris left on the surface of the metal sheet after cutting can easily scratch the surface of the metal sheet. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a metal sheet cutting device for the production of daily-use metal products, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal sheet cutting device for the production of daily-use metal products, comprising a base and a clamp, wherein the clamp is slidably mounted on the surface of the base, and an electric telescopic rod is provided on the surface of the base, the free end of which is fixedly connected to the clamp. The electric telescopic rod pushes the clamp to move, moving the metal sheet to the cutting area. A motor is provided on the surface of the base, and a cutter is fixedly mounted on the output end of the motor. A fixing frame is fixedly mounted on the surface of the base, and a pressure roller is sleeved on the fixing frame. The pressure roller is positioned on the moving path of the metal sheet, and during the cutting process, the cut-off portion is always... The metal sheet is pressed by the pressure roller to prevent it from warping upwards due to the shearing force of the cutter during the cutting process. This keeps the metal sheet straight throughout the cutting process and ensures a neat cut surface. The pressure roller has a screw groove on its surface, and a hook is slidably mounted on the surface of the fixing frame. A spring is installed between the hook and the fixing frame. As the metal sheet moves, it pushes the pressure roller to rotate. When the screw groove on the surface of the pressure roller rotates, it pushes the hook to move. When the hook moves, it squeezes the spring, which contracts and accumulates elastic force. This elastic force is then transmitted to the surface of the pressure roller through the hook. The pressure roller applies a pushing force to the surface of the metal sheet, causing the cut part of the metal sheet to separate from the body along a straight path, resulting in a uniform and neat cut surface.

[0007] According to the above technical solution, a stop bar is fixedly installed on the surface of the fixed frame, a collar is slidably installed inside the pressure roller, and connecting rods are hinged to both sides of the collar. A sliding frame is slidably installed inside the pressure roller, and grinding blocks are slidably installed on both sides of the sliding frame. The grinding blocks are hinged to the connecting rods. When the pressure roller pushes out the metal sheet, the grinding blocks extend from inside the pressure roller. As the pressure roller rotates and resets, the grinding blocks drive the cutting surface to grind the end of the cutting surface, remove burrs, and make the cutting surface smoother.

[0008] According to the above technical solution, a first torsion spring is provided between the pressure roller and the fixed frame. The elastic force of the first torsion spring causes the pressure roller to rotate and reset. A first spring is provided between the grinding block and the slide frame. The elastic force of the first spring causes the grinding block to reset. At the same time, it provides support force between the connecting rod and the grinding block. When the collar moves, the connecting rod first pushes the slide frame to move. When the slide frame presses against the inner wall of the pressure roller, the connecting rod pushes the grinding block to move.

[0009] According to the above technical solution, the base surface is provided with a hollow and an inclined plate. After the pressure roller pushes out the metal sheet, the metal sheet slides down the inclined plate onto the base surface for stacking. An alignment plate is slidably installed on the base surface. The alignment plate is sleeved on the surface of the pressure roller. When the pressure roller moves, it drives the alignment plate to move, pushing the metal sheet so that the stacked metal sheets are aligned with each other, stacked neatly, and saving stacking space. Several sliding rollers are provided between the hollow inner wall and the inclined plate. The rolling of the pressure roller reduces the friction force on the bottom of the metal sheet, allowing the metal sheet to move under the push of the pressure roller.

[0010] According to the above technical solution, a push plate is slidably installed on the surface of the base, a push rod is sleeved on the surface of the push plate, a second spring is provided between the push plate and the push rod, a hook plate is slidably installed on the surface of the clamp, a third spring is provided between the hook plate and the clamp, a notch is opened on the surface of the base, and each time the hook plate moves to the bottom of the notch, the hook plate will spring up and enter the notch, a rotating block is rotatably installed on the surface of the push rod, a second torsion spring is provided between the rotating block and the push rod, the rotating block is reset under the elastic force of the second torsion spring, and a stop block is fixedly installed on the surface of the push rod near the rotating block.

[0011] According to the above technical solution, a slider is slidably mounted on the surface of the alignment plate, and a rocker arm is rotatably mounted on the surface of the alignment plate near the slider. When the stacked metal sheets reach a specified height, the slider will be squeezed and moved by the metal sheets when the alignment plate pushes towards the metal sheets again. When the slider moves, it squeezes the rocker arm to rotate. A third torsion spring is provided between the rocker arm and the alignment plate. The elastic force of the third torsion spring causes the rocker arm to return to its original position. A slide bar is slidably mounted on the surface of the alignment plate near the rocker arm. After the rocker arm rotates, it squeezes the slide bar to move. A fourth spring is provided between the slide bar and the alignment plate. The elastic force of the fourth spring causes the slide bar to return to its original position. A slider is slidably mounted on the surface of the push plate. The slider and... A fifth spring is provided between the push plates. A hook is rotatably mounted on the surface of the slider. The hook surface is provided with an inclined surface. A baffle is fixedly installed on the surface of the alignment plate near the push plate. When the hook is reset, the baffle presses against the inclined surface of the hook surface, and the hook rotates upward. The top of the baffle has a slot and a notch. The hook is in the slot. The push plate is limited by the hook being sleeved in the slot. When the slide rod pushes the slider to move, it drives the hook to align with the notch, releasing the limitation on the push plate. The push plate pushes out the stacked metal sheets under the push rod, realizing automatic stacking of metal sheets. Each stack of metal sheets has a uniform height, which is convenient for workers to sort and recycle.

[0012] According to the above technical solution, the surface of the push plate is provided with several air holes, which are connected to the interior of the push plate. When the push plate is fixed, the push rod moves and squeezes the gas inside the push plate, causing the gas to be discharged from the air holes. Under the action of the airflow, the metal debris on the surface of the stacked metal sheets falls off. The surface of the base is provided with several slots, and a collection drawer is installed inside the base. The collection drawer is located below the slots, and the fallen metal debris falls through the slots into the collection drawer for centralized collection.

[0013] According to the above technical solution, a plurality of rotating bars are rotatably installed on the surface of the base near the trough, a reciprocating plate is slidably installed on the surface of the base, an inclined surface is provided on the side of the reciprocating plate near the alignment plate, a plurality of protruding rods are fixedly installed on the surface of the reciprocating plate, an opening is opened on the surface of the rotating bars, and the protruding rods are sleeved in the opening. When the reciprocating plate moves, it drives the protruding rods to push the opening, causing the rotating bars to rotate and tilt, pouring the debris on the surface into the collection drawer. A sixth spring is provided between the reciprocating plate and the base.

[0014] This invention provides a metal sheet cutting device for the production of daily-use metal products. It has the following beneficial effects: (1) The invention uses a pressure roller to limit the metal sheet, which prevents the metal sheet from warping during the cutting process and keeps the metal sheet straight throughout the cutting process, ensuring a flat cutting surface. At the same time, the pressure roller assists the metal sheet to detach, preventing the end connection of the metal sheet from warping when it is about to separate from the body, which would cause uneven cutting. During the process of the pressure roller pushing the metal sheet out, the internal grinding block extends to grind the residual burrs on the cutting surface of the metal sheet, making the cutting surface flatter.

[0015] (2) In this invention, the pressure roller pushes out the metal sheet so that the metal sheet is stacked on the base surface. The movement of the alignment plate makes the metal sheet align with each other and stack neatly. Whenever the metal sheet is stacked to a specified height, the push plate pushes out the metal sheet to stack the next pile of metal sheets, realizing the stacking of metal sheets. Moreover, the height of each pile of metal sheets is uniform, eliminating the need for workers to manually place the metal sheets, making it easier for workers to sort and recycle the metal sheets, and improving work efficiency.

[0016] (3) In this invention, when the stacked metal sheets do not reach the specified height, the push rod squeezes the gas inside the push plate, causing the gas to be discharged from the air hole. Through the airflow, the metal debris on the surface of the stacked metal sheets falls off, ensuring that the surface of the metal sheets is clean and avoiding scratches caused by friction between the metal sheets and debris during subsequent transfer. Under the reciprocating movement of the alignment plate, the rotating bar rotates and tilts, pouring the debris on the surface into the collection drawer, accelerating the movement of the debris away from the base surface.

[0019] 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.

[0020] Please see Figures 1-11 One embodiment of the present invention is: a metal sheet cutting device for the production of daily-use metal products, including a base 1 and a clamp 2. The clamp 2 is slidably mounted on the surface of the base 1. An electric telescopic rod 3 is provided on the surface of the base 1. The free end of the electric telescopic rod 3 is fixedly connected to the clamp 2. The clamp 2 is moved by the electric telescopic rod 3 to move the metal sheet to the cutting area. A motor 4 is provided on the surface of the base 1. A cutter 5 is fixedly mounted on the output end of the motor 4. A fixed frame 6 is fixedly mounted on the surface of the base 1. A pressure roller 7 is sleeved on the fixed frame 6. The pressure roller 7 is set on the moving path of the metal sheet. During the cutting process, the cut-off part is always crushed by the pressure roller 7 to prevent it from warping upward due to the shearing force of the cutter 5 during the cutting process. A screw groove 8 is opened on the surface of the pressure roller 7. A hook 9 is slidably mounted on the surface of the fixed frame 6. A force-accumulating spring 10 is provided between the hook 9 and the fixed frame 6. During the movement of the metal sheet, the pressure roller 7 is pushed to rotate. When the screw groove 8 on the surface of the pressure roller 7 rotates, it pushes the hook 9 to move. When the hook 9 moves, it squeezes the force-accumulating spring 10. The force-accumulating spring 10 contracts and accumulates elastic force.

[0021] A stop bar 11 is fixedly installed on the surface of the fixed frame 6. A collar 12 is slidably installed inside the pressure roller 7. A connecting rod 13 is hinged to both sides of the collar 12. A sliding frame 15 is slidably installed inside the pressure roller 7. Grinding blocks 14 are slidably installed on both sides of the sliding frame 15. The grinding blocks 14 are hinged to the connecting rod 13. When the pressure roller 7 pushes out the metal sheet, the grinding blocks 14 extend out from inside the pressure roller 7. As the pressure roller 7 rotates and resets, it drives the grinding blocks 14 to grind the end of the cut surface.

[0022] A first torsion spring is provided between the pressure roller 7 and the fixed frame 6. The elastic force of the first torsion spring causes the pressure roller 7 to rotate and return to its original position. A first spring is provided between the grinding block 14 and the slide frame 15. The elastic force of the first spring causes the grinding block 14 to return to its original position.

[0023] In this embodiment, the metal sheet to be cut is placed in the clamp 2 and clamped. The equipment is started, and the motor 4 and the electric telescopic rod 3 begin to work. The output end of the motor 4 drives the cutter 5 to rotate, and the electric telescopic rod 3 drives the clamp 2 to move, pushing the metal sheet towards the cutter 5. The metal sheet is cut by the high-speed rotation of the cutter 5. After the metal sheet approaches the cutter 5, it enters the bottom of the pressure roller 7. During the cutting process, the cut portion is always crushed by the pressure roller 7 to prevent it from warping upwards due to the shearing force of the cutter 5. This keeps the metal sheet straight and the cut surface neat throughout the cutting process. At the same time, as the metal sheet moves at the bottom of the pressure roller 7, it pushes the pressure roller 7 to rotate. When the pressure roller 7 rotates, it drives the surface groove 8 to rotate. When the groove 8 rotates, it pushes the hook 9 to move. After the hook 9 moves, it squeezes the storage. The spring 10 contracts and deforms, accumulating elastic force. At the same time, the hook 9 pulls the pressure roller 7, transferring the accumulated elastic force of the spring 10 to the surface of the pressure roller 7. When the cut part of the metal sheet is about to detach from the body, the pressure roller 7 immediately moves the metal sheet out and quickly separates it from the body through the elastic force of the spring 10. During the cutting process of the metal sheet, the surface of the metal sheet will be subjected to the pressure of the cutter 5. The cut part of the metal sheet will warp with the cutting point of the cutter 5 as the fulcrum. The closer to the end of the cutting, the lower the rigidity of the connection between the cut part and the body. During the separation process from the body, the end connection will be twisted under the warping phenomenon, resulting in an uneven end of the cut surface. The pressure roller 7 applies a pushing force to the surface of the metal sheet, so that the cut part of the metal sheet separates from the body in a straight path, making the end of the cut surface uniform and neat.

[0024] After the pressure roller 7 moves, the collar 12 contacts the abutment rod 11. The abutment rod 11 squeezes the collar 12, pushing the collar 12 to move. The collar 12 pushes the slide frame 15 to move through the connecting rod 13. After the slide frame 15 moves, it drives the grinding block 14 to extend out from inside the pressure roller 7. When the slide frame 15 presses against the inner wall of the pressure roller 7, it stops moving. The collar 12 continues to move and squeezes the connecting rod 13 to deflect and push the grinding block 14 to slide out from the surface of the slide frame 15. As the pressure roller 7 rotates and resets, it drives the grinding block 14 to rotate and rub and grind the metal sheet cutting surface to eliminate burrs on the cutting surface and make the cutting surface smoother.

[0025] Please see Figures 1-11 Based on the above embodiments, in another embodiment of the present invention, the surface of the base 1 is provided with a hollow and an inclined plate 17 is provided. After the pressure roller 7 pushes out the metal sheet, the metal sheet slides down the inclined plate 17 to the surface of the base 1 for stacking. An alignment plate 18 is slidably installed on the surface of the base 1. The alignment plate 18 is sleeved on the surface of the pressure roller 7. When the pressure roller 7 moves, it drives the alignment plate 18 to move, pushing the metal sheet so that the stacked metal sheets are aligned with each other, stacked neatly, and saving stacking space. A number of sliding rollers 16 are provided between the hollow inner wall and the inclined plate 17. The rolling of the sliding rollers 16 reduces the friction force on the bottom of the metal sheet.

[0026] A push plate 19 is slidably mounted on the surface of the base 1, and a push rod 20 is sleeved on the surface of the push plate 19. A second spring is provided between the push plate 19 and the push rod 20. A hook plate 22 is slidably mounted on the surface of the clamp 2, and a third spring is provided between the hook plate 22 and the clamp 2. The elastic force of the third spring causes the hook plate 22 to lift up. A notch 23 is opened on the surface of the base 1. Each time the hook plate 22 moves to the bottom of the notch 23, the hook plate 22 will spring up and enter the notch 23. A rotating block 21 is rotatably mounted on the surface of the push rod 20. A second torsion spring is provided between the rotating block 21 and the push rod 20. The rotating block 21 is reset under the elastic force of the second torsion spring. A stop block 24 is fixedly mounted on the surface of the push rod 20 near the rotating block 21. The stop block 24 limits the rotating block 21 on one side, so that the rotating block 21 can only rotate in one direction.

[0027] A slider 26 is slidably mounted on the surface of the alignment plate 18. A rocker arm 27 is rotatably mounted on the surface of the alignment plate 18 near the slider 26. When the stacked metal sheets reach a specified height, the slider 26 will be squeezed and moved by the metal sheets when the alignment plate 18 pushes the metal sheets again. When the slider 26 moves, it squeezes the rocker arm 27 to rotate. A third torsion spring is provided between the rocker arm 27 and the alignment plate 18. The elastic force of the third torsion spring causes the rocker arm 27 to return to its original position. A slider 28 is slidably mounted on the surface of the alignment plate 18 near the rocker arm 27. After the rocker arm 27 rotates, it squeezes the slider 28 to move. A fourth spring is provided between the slider 28 and the alignment plate 18. The elastic force of the fourth spring causes the slider 28 to return to its original position. A slider 29 is slidably mounted on the surface of the push plate 19. A fifth spring is provided between the push plate 19 and the slide 29. The elastic force of the fifth spring causes the slide 29 to return to its original position. A hook 30 is rotatably mounted on the surface of the slide 29. The surface of the hook 30 is provided with an inclined surface. A baffle 25 is fixedly installed on the surface of the base 1 of the alignment plate 18 near the push plate 19. When the hook 30 returns to its original position, the baffle 25 presses against the inclined surface of the hook 30, causing the hook 30 to rotate upward. The top of the baffle 25 has a slot 31 and a notch 32. The hook 30 is located in the slot 31. The push plate 19 is limited by the hook 30 being fitted in the slot 31. When the slide rod 28 pushes the slide 29 to move, it causes the hook 30 to align with the notch 32, releasing the limitation on the push plate 19. The push plate 19 pushes out the stacked metal sheets under the push of the push rod 20. In this embodiment, during operation: the metal sheet cutting section separates from the main body under the push of the pressure roller 7, and after rolling transition through the sliding roller 16, slides down along the inclined plate 17 and stacks on the surface of the base 1, eliminating the need for manual removal and improving work efficiency. Simultaneously, the pressure roller 7 rotates and resets under the elastic force of the first torsion spring, pushing the alignment plate 18 towards the stacked metal sheets, aligning them neatly and saving stacking space. Meanwhile, when the clamp 2 moves, it drives the hook plate 22 to move. After the hook plate 22 moves, it pushes the rotating block 21 to rotate past the rotating block 21. After the rotating block 21 rotates, it resets under the elastic force of the second torsion spring. When the clamp 2 resets after cutting, it drives the hook plate 22 to reset, hooking the rotating block 21 and moving it to move the push rod 20 towards the push plate 19. The push plate 19 is connected to the push rod 20 via a second spring. At this time, the push plate 19 is limited by the hook 30 hanging on the surface of the baffle 25 and will not be pushed by the push rod 20. When the metal sheets are stacked to a certain height, when the alignment plate 18 pushes the metal sheets again, the metal sheets will squeeze the slide bar 26 to move. After the slide bar 26 moves, it squeezes the rocker arm 27 to rotate. After the rocker arm 27 rotates, it pushes the slide bar 28 to move and push the slider 29 open. The slider 29 drives the hook 30 to move to align with the notch 32, releasing the limitation of the slot 31 on the hook 30. At this time, when the push rod 20 moves towards the push plate 19, it can indirectly push the push plate 19 to move through the second spring. The push plate 19 removes the stacked metal sheets. The alignment plate 18 neatly stacks the cut metal sheets each time, and pushes them out when they are stacked to a certain height, realizing automatic stacking of metal sheets. Each stack of metal sheets has a uniform height, which is convenient for workers to sort and recycle.

[0028] Please see Figures 1-11 Based on the above embodiments, in another embodiment of the present invention, the surface of the push plate 19 is provided with a plurality of air holes 33, which are connected to the interior of the push plate 19. When the push plate 19 is fixed, the push rod 20 moves and squeezes the gas inside the push plate 19, causing the gas to be discharged from the air holes 33. Under the action of the airflow, the metal debris on the surface of the stacked metal sheet falls off, avoiding the metal debris from scratching the surface of the metal sheet. The surface of the base 1 is provided with a plurality of slots 34, and a collection drawer 35 is installed inside the base 1. The collection drawer 35 is located below the slots 34, and the fallen metal debris falls through the slots 34 into the collection drawer 35 for centralized collection.

[0029] Several rotating bars 36 are rotatably installed on the surface of the base 1 near the trough 34. A reciprocating plate 37 is slidably installed on the surface of the base 1. An inclined surface is provided on the side of the reciprocating plate 37 near the alignment plate 18. Several protruding rods 38 are fixedly installed on the surface of the reciprocating plate 37. An opening 39 is opened on the surface of the rotating bars 36. The protruding rods 38 are sleeved in the opening 39. When the reciprocating plate 37 moves, it drives the protruding rods 38 to push the opening 39, causing the rotating bars 36 to rotate and tilt, pouring the surface debris into the collection drawer 35. A sixth spring is provided between the reciprocating plate 37 and the base 1. The elastic force of the sixth spring causes the reciprocating plate 37 to return to its original position.

[0030] In this embodiment, when the stacked metal sheets do not reach the specified height, the push rod 20 cannot push the push plate 19 to move. Instead, it pushes and pulls inside the push plate 19, squeezing the gas inside the push plate 19 and causing the gas inside the push plate 19 to be discharged through the air hole 33. Under the action of airflow, the metal debris on the surface of the stacked metal sheets falls off, ensuring the surface of the metal sheets is clean and avoiding scratches caused by friction between the metal sheets and debris during subsequent transfer. The fallen metal debris falls through the trough 34 into the collection drawer 35 for centralized collection, ensuring the cleanliness of the working area on the surface of the base 1. At the same time, the alignment plate 18 will squeeze the inclined surface of the reciprocating plate 37 during each movement and reset, pushing the reciprocating plate 37 to move. When the reciprocating plate 37 moves, it drives the protruding rod 38 to push the opening 39 to make the rotating bar 36 rotate and tilt, pouring the debris on the surface into the collection drawer 35, and accelerating the removal of debris from the surface of the base 1.
