Description

Technical Field

[0001] This invention relates to the field of cutting and blanking technology, specifically to a rapid blanking device for sheet metal parts after laser cutting. Background Technology

[0002] Laser cutting, also known as laser cutting, is a modern metal processing technology that uses lasers to cut metal into specific shapes. This technology generally requires a computer-controlled laser cutting machine. After laser cutting, the sheet metal parts need to be removed. With the increasing market demand for sheet metal parts, laser cutting equipment, with its high precision, high efficiency, and high-quality cutting results, can meet the needs of manufacturing enterprises for sheet metal processing, thus having a broad market prospect. It utilizes a high-energy-density laser beam to irradiate the sheet metal material, causing the material to melt or vaporize instantly, thereby achieving precise cutting. The cut sheet metal parts are then separated from and removed from the raw material.

[0003] Traditional sheet metal processing requires operators to frequently and manually place individual sheet metal pieces onto the processing table, cut them, and then manually remove them. This results in long equipment idle times, low production efficiency, and the separate processes of loading, unloading, positioning, cutting, and unloading, making continuous production impossible. Each sheet metal requires individual laser positioning (edge ​​finding, origin finding), which takes up cutting time. Traditional laser cutting machines, loading machines, and unloading machines are often independent units, requiring additional conveyor belts or robots for connection, resulting in a huge floor space for the entire production line. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rapid unloading device for sheet metal parts after laser cutting, thus solving the problem.

[0006] Preferably, a limiting lifting frame is suspended above the support frame, a laser receiving platform is fixed inside the limiting lifting frame, a cutting slide is embedded in the top of the limiting lifting frame, and laser cutting elements are provided at both ends of the cutting slide.

[0007] Preferably, the central gear disk rotates on the top of the component frame and is located between the component frame and the bearing working groove. A short-distance traction rod is fixed to the top axis of the central gear disk, and the long-distance traction rod rotates at the end of the short-distance traction rod away from the central gear disk.

[0008] Preferably, the misaligned output mechanism includes an embedded slide block that slides within a closed-loop limiting groove.

[0014] Preferably, the bidirectional rail has a retaining spring structure embedded inside, and is disposed between the material feeding channel and the bidirectional rail.

[0015] This invention provides a rapid unloading device for sheet metal parts after laser cutting. It has the following beneficial effects: 1. This invention features high integration and automation: The equipment integrates the input hopper, laser cutting area, and output function into one unit, realizing continuous feeding, cutting, and unloading of strip sheet metal parts without manual intervention, greatly reducing downtime. It is suitable for mass production scenarios. Through the coordination of traction belt, closed-loop track, and push mechanism, the equipment automatically completes feeding and cutting in horizontal reciprocating motion and triggers unloading action at specific positions, forming a closed-loop production process and significantly improving production efficiency.

[0016] 2. This invention features an ingenious mechanical transmission design: a traction belt drives the reciprocating motion of the reversing traction card and component frame, ensuring precise and controllable linear displacement of the carrying work trough and input hopper. Simultaneously, the reversing design allows for dual-sided utilization of the belt, improving transmission efficiency and lifespan. The embedded slide slides within the closed-loop traction rail, achieving smooth turning through the docking collar, ensuring stable operation of the mechanism in complex trajectories. The inclined platform and the ramp of the pushing shaft engage, triggering the lifting action only at specific positions, precisely controlling the material feeding timing. The meshing design of the pushing gear rack and the central gear disc ensures reliable power transmission, triggering the feeding action only when the mechanism reaches its end, avoiding misoperation and ensuring synchronization between the pushing rhythm and the cutting cycle.

[0017] 3. This invention has flexible production adaptability: the position of the cutting carriage on the limiting lifting frame can be adjusted, allowing users to flexibly set the cutting area according to the sheet metal parts specifications and cutting requirements, adapting to workpieces of different sizes and processing requirements. Through the gravity reset design of the pushing limiting mechanism, the feeding action is only triggered when the equipment runs to a specific position, and feeding stops at other times, avoiding redundant operations, while supporting the needs of different production cycles.

[0018] 4. This invention features optimized spatial layout: the horizontal movement of the component frame and the vertical lifting action of the jacking mechanism are separated, reducing mechanical interference, optimizing space utilization, making the equipment structure compact and highly integrated. The laser receiving platform is stationary, while the workpiece is moved relative to the workpiece in the working material placement channel, reducing the need for laser emitter movement, simplifying the system structure, and improving cutting accuracy and stability.

[0019] 5. This invention features high reliability and easy maintenance: the top-pushing limit mechanism relies on gravity for reset, and the push-pull key rack automatically disengages from the meshing position, reducing reliance on electrical or sensor components, lowering the failure rate and maintenance costs. The input hopper, misaligned output mechanism, and material discharge traction mechanism are relatively independent, making them easy to disassemble, replace, or repair, thus improving the maintainability and service life of the equipment.

[0020] 6. This invention is suitable for high-intensity continuous operation: the input hopper can temporarily store multiple sheet metal parts, and the material is continuously supplied through the circulating pushing mechanism, supporting long-term continuous production and meeting the high load requirements in industrial scenarios. The traction belt, closed-loop track and key meshing parts adopt durable materials and structural design to ensure that the equipment maintains long-term stable operation in frequent reciprocating motion.

The top of the card 17 has a rotating traction displacement shaft 16. A shifting traction groove 15 is provided in the middle of the component frame 4. The top of the traction displacement shaft 16 slides inside the shifting traction groove 15. A working material placement channel 18 is fixed at the center of the top of the component frame 4, and a cutting passage is provided in the middle. The inlet of the working material placement channel 18 is connected to the outlet of the input hopper 10 for conveying. A material unloading traction mechanism 21 is also provided at the top of the component frame 4, in front of the carrying working channel 5. A limiting lifting frame 7 is suspended above the bearing frame 1. A laser receiving platform 8 is fixed inside the limiting lifting frame 7. A cutting carriage 9 is embedded and slidable at the top of the limiting lifting frame 7. Laser cutting elements are provided at both ends of the cutting carriage 9. A guide groove 19 is provided between the carrying working channel 5 and the working material placement channel 18, simultaneously... The bottom wall of the material feeding trough 18 is provided with a limiting groove 20. A fixing clip 22 is fixed to the side wall of the component frame 4. A suspension shaft 23 is fixed to the bottom of the fixing clip 22. A closed-loop traction rail 24 is fixed to the top of the support frame 1 and surrounds the outside of the traction belt 13. A closed-loop limiting groove 26 is provided inside the closed-loop traction rail 24. A misalignment output mechanism 25 is embedded inside the closed-loop limiting groove 26. A traction suspension frame 27 slides on the top of the closed-loop traction rail 24. A pushing toothed key 28 is fixed to the top of the traction suspension frame 27. A pushing limiting mechanism 29 is fixed to one end of the traction suspension frame 27 extending into the closed-loop traction rail 24. A bidirectional locking rail 30 is fixed to the bottom of the input hopper 10. The bidirectional locking rail 30 has a two-layer slide structure with interconnected slides. A pusher insertion channel 31 is fixed to the bottom of the inner side wall. A retaining spring structure is embedded inside the bidirectional retaining rail 30 and is located between the pusher insertion channel 31 and the bidirectional retaining rail 30. An auxiliary rail 32 is fixed to the bottom of the bidirectional retaining rail 30. The auxiliary rail 32 extends through the side wall of the bearing working groove 5 into the interior of the bearing working groove 5 and is located between the bearing working groove 5 and the component frame 4. A linkage input mechanism 33 is provided at the lower part of the input hopper 10. A through groove structure is provided in the middle of the pusher insertion channel 31. This equipment is designed for laser cutting of strip sheet metal parts and includes synchronous input and output unloading operations. The strip sheet metal parts are first placed in batches inside the input hopper 10. By opening the suspension frame 14, the rotational torque generated is output to the traction wheel 12 installed through the opposing plate frame 11.The rotation of a single traction wheel 12 simultaneously transmits torque to the traction wheel 12 mounted on the other side of the opposing plate frame 11 via the traction belt 13. The traction belt 13 itself also operates simultaneously, and the reversing traction clamp 17 fixed to the outer surface of the traction belt 13 also moves with the operation of the traction belt 13, following its shape. After completing the operation on one side of the traction belt 13, the reversing traction clamp 17 moves to the other side of the traction belt 13. The traction displacement shaft 16 mounted on its top also slides back and forth inside the reversing traction groove 15 set in the component frame 4, causing the component frame 4 to move linearly left and right along the two side slides 2 set on the top of the bearing slide 3 on the bearing frame 1, until it moves to one end and the other end of the traction belt 13. The bearing working groove 50 fixed on the top of the component frame 4... The component frame 4 moves along with the displacement of the component frame 4. At the same time, the input hopper 10, which temporarily stores the strip-shaped sheet metal parts, also moves along with the displacement of the bearing working groove 5. As the component frame 4 moves, the misaligned output mechanism 25, which is fixed by the fixing clip 22 and the suspension shaft 23, slides along the closed-loop limiting groove 26 inside the closed-loop traction rail 24 at the top of the bearing frame 1. The external shape of the closed-loop traction rail 24 is the same as that of the traction belt 13, so that the misaligned output mechanism 25 can slide along the trajectory of the closed-loop traction rail 24. Displacement: As the equipment drives the bearing working groove 5 and component frame 4 to move back and forth, the laser receiving table 8 passes through the guide groove 19 set between the bearing working groove 5 and the working material placement groove 18, and in a static state, forms a relative reciprocating motion with the working material placement groove 18 and the meter head inside the working material placement groove 18. At the same time, the bottom of the strip-shaped sheet metal part moves linearly back and forth on the laser receiving table 8, while the cutting carriage 9 suspended on the top of the limiting lifting frame 7 is located on the sheet metal part carried by the working material placement groove 18. Above, as the sheet metal part moves back and forth along the working material placement channel 18, it reciprocates in contact with the laser cutting elements at both ends of the cutting carriage 9. In conjunction with the central section of the working material placement channel 18, it performs laser cutting on the sheet metal part. Simultaneously, the position of the cutting carriage 9 on the limiting lifting frame 7 can be adjusted to change the cutting area of ​​the sheet metal part. When the misalignment output mechanism 25 enters the curved section of the closed-loop traction rail 24 and the closed loop... When the traction rail 24 slides on the other side, the push-up inclined platform 252 disengages from the push-up shaft 291, causing the push-up limiting mechanism 29 to fall due to gravity, pulling the traction suspension frame 27 and the pushing gear key 28. The pushing gear key 28 moves away from the height of the unloading traction mechanism 21, and the reciprocating unloading traction mechanism 21 stops operating, thus stopping the feeding until the next set of strip sheet metal parts is pushed in. At the same time, the previously processed strip sheet metal parts are pushed out, achieving the ability to simultaneously feed and discharge strip sheet metal parts while cutting them in batches.

[0025] Please see the appendix Figure 1 - Appendix Figure 5The unloading traction mechanism 21 includes a central gear disk 211 and a long-distance traction rod 213. The central gear disk 211 rotates on the top of the component frame 4 and is located between the component frame 4 and the bearing working groove 5. A short-distance traction rod 212 is fixed to the top axis of the central gear disk 211. The long-distance traction rod 213 rotates at the end of the short-distance traction rod 212 away from the central gear disk 211. The pushing key bar 28 rises to the height of the unloading traction mechanism 21 inside the component frame 4. At this height, the pushing key bar 28 can be aligned with the central gear disk 211 included in the unloading traction mechanism 21. 11. After the central gear disk 211, which has been displaced to the position of the push key bar 28, contacts and meshes with the push key bar 28, it drives the central gear disk 211 to rotate through the key meshing relationship. The short-distance traction rod 212, which is fixed on the axis of the central gear disk 211, also rotates. The outer end of the short-distance traction rod 212 simultaneously drives one end of the long-distance traction rod 213 to perform centrifugal rotation. Meanwhile, the linkage input mechanism 33, which is installed and docked on the other end of the long-distance traction rod 213, also operates inside the bidirectional clamping rail 30 and auxiliary rail 32 set at the bottom of the input hopper 10.

[0026] Please see the appendix Figure 1 - Appendix Figure 7 The misalignment output mechanism 25 includes an embedded slide 251, which slides within a closed-loop limiting groove 26. A pushing ramp 252 is provided inside the embedded slide 251. A docking collar 253 is fixed to the side wall of the embedded slide 251, and the inner ring of the docking collar 253 is fixed to the bottom end of the suspension shaft 23. The embedded slide 251 of the misalignment output mechanism 25 slides along the closed-loop limiting groove 26 provided inside the closed-loop traction rail 24. When encountering a bend in the closed-loop traction rail 24, the docking collar 253 fixed to the side of the embedded slide 251 will... Rotating on the shaft 23 allows the embedded slide 251 to make turns and slide. When the misalignment output mechanism 25 moves with the component frame 4 to the end of the side slide 2 and the traction suspension 27, the misalignment output mechanism 25 directly contacts the push limiting mechanism 29 located at the bottom of the traction suspension 27 and inside the closed-loop traction rail 24. The ramp structure of the push ramp 252 fixed inside the embedded slide 251 contacts the push ramp 292 structure at the end of the push shaft 291, and the push shaft 291 is lifted as a whole inside the closed-loop limiting groove 26.

[0027] Please see the appendix Figure 1 - Appendix Figure 8The push-limiting mechanism 29 includes a push-shaft 291, which is fixed to the bottom end of the traction suspension 27. The push-shaft 291 is set in the closed-loop limiting groove 26. A push-incline 292 is provided on one side of the push-shaft 291. The height of the push-shaft 291 is lower than the groove depth of the closed-loop limiting groove 26. The misalignment output mechanism 25 directly contacts the push-limiting mechanism 29 located at the bottom end of the traction suspension 27 and inside the closed-loop traction rail 24. The slope structure of the push-incline 252 fixed inside the slide block 251 contacts the push-incline 292 structure at the end of the push-shaft 291. The push-shaft 291 is lifted as a whole inside the closed-loop limiting groove 26. At the same time, the traction suspension 27 and the push-pull key 28 fixed at the top of the push-shaft 291 are lifted as a whole.

[0028] Please see the appendix Figure 1 - Appendix Figure 11 The linkage input mechanism 33 includes an embedded pull rod 331, which slides on the lower part of the bidirectional rail 30. The bottom end of the embedded pull rod 331, near the bearing working groove 5, rotates to the outer end of the long-distance traction rod 213. An extension push rod 332 is fixed to the top of the embedded pull rod 331 on the side away from the bearing working groove 5. An input push plate 333 is fixed to the top of the extension push rod 332. The input push plate 333 slides on the side wall of the material insertion channel 31. Under the centrifugal motion of one end of the long-distance traction rod 213, the embedded pull rod 331 included in the linkage input mechanism 33 begins to move along the auxiliary rail 32 toward the interior of the bearing working groove 5. At the same time, the extension push rod 332 added to the top of the embedded pull rod 331 also moves along the auxiliary rail 32 toward the interior of the bearing working groove 5. The bidirectional rail 30 is displaced and pushes the spring structure between the bidirectional rail 30 and the pusher insertion channel 31 to compress. The embedded pull rod 331 also extends into the pusher insertion channel 31 through the through groove structure at the bottom of the pusher insertion channel 31. The strip-shaped sheet metal parts temporarily stored in the input hopper 10 fall along the structure of the input hopper 10, so that the bottommost strip-shaped sheet metal parts fall onto the pusher insertion channel 31. The input push plate 333 at the top of the extension push rod 332 slides inside the pusher insertion channel 31, pushing the entire strip-shaped sheet metal part into the working material placement channel 18, and causing the strip-shaped sheet metal part to move along the cutting slide 9 on the side wall of the laser receiving table 8 to the laser receiving table 8 fixed at the top of the limiting lifting frame 7.

[0029] Working Principle: This equipment is designed for laser cutting of strip-shaped sheet metal parts. It includes synchronous input and output unloading operations. The strip-shaped sheet metal parts are first placed in batches inside the input hopper 10. By opening the suspension frame 14, the rotational torque generated is output to the traction wheel 12 mounted on the opposing plate frame 11. The rotation of a single traction wheel 12 simultaneously transmits the torque to the traction wheel 12 mounted on the other side of the opposing plate frame 11 via the traction belt 13. The traction belt 13 itself also operates simultaneously, and the reversing traction clamp 17 fixed to the outer surface of the traction belt 13 also moves accordingly. The traction belt 13 moves in accordance with its external structure. After the reversing traction clamp 17 completes the operation on one side of the traction belt 13, it moves to the other side of the traction belt 13. At the same time, the traction displacement shaft 16 installed on its top slides back and forth inside the reversing traction groove 15 set in the component frame 4. Simultaneously, the component frame 4 moves linearly left and right along the two side slides 2 set on the top of the bearing slide 3 on the bearing frame 1, until it moves to one end and the other end of the traction belt 13. The bearing working groove 50 fixed on the top of the component frame 4... The component frame 4 moves along with the component frame 4. Simultaneously, the input hopper 10, which temporarily holds the strip-shaped sheet metal parts, moves along with the bearing work trough 5. As the component frame 4 moves, its misaligned output mechanism 25, fixed via the fixing clip 22 and suspension shaft 23, slides along the closed-loop limiting groove 26 inside the closed-loop traction rail 24 at the top of the support frame 1. The external shape of the closed-loop traction rail 24 is the same as the traction belt 13, allowing the misaligned output mechanism 25 to slide along the trajectory of the closed-loop traction rail 24. The embedded slide 251 included in the misaligned output mechanism 25 slides along the closed-loop limiting groove 26 inside the closed-loop traction rail 24. When encountering a bend in the closed-loop traction rail 24, the mating collar 253 fixed to the side of the embedded slide 251 rotates on the suspension shaft 23, allowing the embedded slide 251 to make a turning motion. When the misaligned output mechanism 25 moves with the component frame 4 to the end of the side slide 2, the traction suspension... When the frame 27 is in motion, the misaligned output mechanism 25 directly contacts the push-limiting mechanism 29 located at the bottom of the traction suspension frame 27 and inside the closed-loop traction rail 24. The ramp structure of the push-up inclined platform 252 fixed inside the slide block 251 contacts the push-up inclined rail 292 structure at the end of the push-up shaft 291. The push-up shaft 291 is lifted as a whole inside the closed-loop limiting groove 26. At the same time, the traction suspension frame 27 and the push-moving key bar 28 fixed at the top of the push-up shaft 291 are lifted as a whole, so that the push-moving key bar 28 rises to the height of the unloading traction mechanism 21 inside the component frame 4. At this height, the push-moving key bar 28 can contact and mesh with the central gear plate 211 included in the unloading traction mechanism 21. After the central gear plate 211, which has moved to the position of the push-moving key bar 28, contacts the push-moving key bar 28, it pushes the central gear plate 211 to rotate through the key meshing relationship. The short-pitch traction rod 212 fixed on the axis of the central gear plate 211 also rotates accordingly.The outer end of the short-distance traction rod 212 simultaneously drives one end of the long-distance traction rod 213 to perform centrifugal rotation. Meanwhile, the linkage input mechanism 33, which is connected to the other end of the long-distance traction rod 213, also operates within the bidirectional guide rail 30 and auxiliary rail 32 located at the bottom of the input hopper 10. Under the centrifugal motion of one end of the long-distance traction rod 213, the embedded pull rod 331 within the linkage input mechanism 33 begins to move along the auxiliary rail 32 towards the interior of the bearing working trough 5. The extension top rod 332 mounted on the top of the embedded pull rod 331 also moves along the bidirectional guide rail 30 and pushes the retaining spring structure between the bidirectional guide rail 30 and the material insertion channel 31 to compress. The embedded pull rod 331 also... The strip-shaped sheet metal parts temporarily stored inside the input hopper 10 fall along the structure of the input hopper 10 through the through groove structure at the bottom of the feeding insertion channel 31. This causes the lowest strip-shaped sheet metal part to fall onto the feeding insertion channel 31. Meanwhile, the input push plate 333 at the top of the extension push rod 332 slides inside the feeding insertion channel 31, pushing the entire strip-shaped sheet metal part into the working material placement channel 18. The strip-shaped sheet metal part is then moved along the cutting slide 9 on the side wall of the laser receiving table 8 to the laser receiving table 8 fixed at the top of the limiting lifting frame 7. As the equipment drives the bearing working channel 5 and the component frame 4 to move back and forth, the laser receiving table 8 passes through the bearing working channel 5. The guide groove 19, located between the work trough 5 and the work material placement channel 18, forms a reciprocating motion relative to the work material placement channel 18 and the meter head within it when stationary. Simultaneously, the bottom of the strip-shaped sheet metal part linearly moves back and forth on the laser receiving table 8. The cutting carriage 9, suspended on top of the limiting lifting frame 7, is positioned above the sheet metal part carried by the work material placement channel 18. As the sheet metal part moves back and forth with the work material placement channel 18, it reciprocates in contact with the laser cutting elements at both ends of the cutting carriage 9. This, combined with the central section of the work material placement channel 18, laser cuts the sheet metal part. The position of the cutting carriage 9 on the limiting lifting frame 7 can be adjusted to change the cutting area of ​​the sheet metal part. The system performs laser cutting on sheet metal parts. Simultaneously, the position of component 9 can be adjusted relative to component 7 to change the cutting area. When the offset output mechanism 25 enters the curved section of the closed-loop traction rail 24 and the slide rail on the other side of the closed-loop traction rail 24, the push-up inclined platform 252 disengages from the push-up shaft 291. This causes the push-up limiting mechanism 29 to fall due to gravity, pulling the traction suspension frame 27 and the pushing gear key 28 down. The pushing gear key 28 moves away from the height of the unloading traction mechanism 21, stopping the reciprocating displacement of the unloading traction mechanism 21 and thus stopping the feeding until the next set of strip sheet metal parts is pushed in. Simultaneously, the previously processed strip sheet metal parts are pushed out, achieving the ability to simultaneously feed and discharge strip sheet metal parts while cutting them in batches.
