Description

Technical Field

[0001] This invention relates to the field of laser cutting technology for metal sheets, and more specifically, to a metal cutting machine tool with continuous feeding. Background Technology

[0002] Laser cutting machines use a laser beam emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting. When processing metal sheets, metal sheet laser cutting machines are also required. Many companies still rely on manual operation during the loading and unloading process of metal cutting machine tools. This is not only inefficient but also prone to worker fatigue and workplace accidents, increasing the company's production costs. Existing automated loading devices mostly use robotic arms. These robotic arms often require a large gripping radius, resulting in an excessively large required safe operating area. At the same time, the complex structural design of these automated loading devices leads to a large overall size of the lathe and high manufacturing costs, which is not conducive to widespread application. Summary of the Invention

[0003] The purpose of this invention is to provide a metal cutting machine tool with continuous feeding to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a continuously feeding metal cutting machine tool is provided, comprising a frame assembly, a laser cutter disposed above the frame assembly, the laser cutter cutting a metal plate, a feeding assembly disposed on one side of the laser cutter, a plurality of metal plates to be processed being placed above the feeding assembly, the feeding assembly moving towards the laser cutter and transporting a metal plate to the top of the frame assembly, the frame assembly transporting the metal plate to below the laser cutter, a clutch device disposed on the side of the frame assembly away from the feeding assembly, the clutch device driving the frame assembly to transport the metal plate, a clamping assembly disposed below the laser cutter, the clamping assembly sliding downward and clamping the metal plate below the laser cutter from both sides, the clamping assembly sliding downward causing the clutch device to slide downward, so that the clutch device no longer drives the frame assembly to rotate, thus fixing the position of the metal plate below the laser cutter.

[0005] As a further improvement to this technical solution, the frame assembly includes a placement frame on which a plurality of rotating rollers are rotatably mounted. The plurality of rotating rollers are connected to each other by a belt. A first helical gear is fixedly sleeved on one end of each rotating roller. A first connecting shaft is provided below the first helical gear. The top end of the first connecting shaft meshes with the first helical gear through a second helical gear. When the first connecting shaft rotates, it drives the plurality of rotating rollers to rotate through the first helical gear. The plurality of rotating rollers transport the metal plate.

[0006] As a further improvement to this technical solution, the clutch device includes a motor fixedly installed on one side of the placement frame. The motor's rotating shaft is fixedly connected to a second connecting shaft. A second gear is rotatably sleeved on the second connecting shaft. A first gear is fixedly installed below the second helical gear. The first gear meshes with the second gear. The motor drives the second connecting shaft to rotate through the rotating shaft. The second connecting shaft drives the first gear to rotate through the second gear. The meshing of the second helical gear and the first helical gear drives several rotating rollers to rotate.

[0007] As a further improvement to this technical solution, a sliding sleeve is slidably fitted below the second gear, and several pins are provided below the second gear. Several pin holes are opened above the sliding sleeve, and the pins are inserted into the pin holes, causing the sliding sleeve to drive the second gear to rotate. A return spring is fitted below the sliding sleeve, and the return spring pushes the sliding sleeve upward, causing the pins to be inserted into the pin holes. The power of the motor is transmitted to the first connecting shaft through the sliding sleeve and the second gear, driving several of the rotating rollers to rotate, and transporting the metal plate from the side of the placement frame away from the motor to the side closer to the motor.

[0008] As a further improvement to this technical solution, the clamping assembly includes a connecting rod that slides up and down below the rotating roller. A slip ring is fixedly connected to one end of the connecting rod near the motor. The slip ring rotates and fits into the outside of the sliding sleeve. The connecting rod drives the sliding sleeve to slide up and down on the second connecting shaft through the slip ring, so that the pin is inserted into or disengaged from the pin hole. Several splines are provided on the side wall of the second connecting shaft, and several spline grooves are provided on the side wall of the sliding sleeve. The sliding sleeve slides on the second connecting shaft or rotates with the second connecting shaft through the spline grooves.

[0009] As a further improvement to this technical solution, a support plate is fixedly installed on the placement frame between several of the rotating rollers. The metal plate stops sliding when it slides onto the support plate. The laser cutter is fixedly installed above the support plate. The rotating rollers cut the metal plate above the support plate. Two fixing plates are slidably installed below the support plate. The fixing plates clamp and fix the metal plate from both sides. A hinge rod is hinged to the bottom of the fixing plate. A hinge seat is fixedly connected above the end of the connecting rod away from the fixing plate. The end of the hinge rod away from the fixing plate is connected to the connecting rod. The connecting rods are hinged together, with two hinged rods hinged at both ends of the hinge seat. A second cylinder is located below the middle section of the connecting rod, and the piston rod of the second cylinder is connected to the connecting rod. The connecting rod is pulled downward by the piston rod, causing it to slide downward. The hinge seat pulls the two hinged rods downward, causing the two fixed plates on the support plate to move closer to the metal plate. At the same time, the downward sliding connecting rod drives the sliding sleeve through the slip ring to press the return spring downward, causing the pin to disengage from the pin hole, so that the second connecting shaft no longer drives the second gear to rotate, and the several rollers stop rotating.

[0010] As a further improvement to this technical solution, the feeding assembly includes a sliding frame with an opening on the side of the sliding frame near the motor. Several metal plates to be processed are placed between the openings of the sliding frame. Two slots are formed on the side of the opening near the motor, and the two slots are respectively set on both sides of the metal plate. An upper clamping plate and a lower baffle are arranged sequentially in the slots. The lower baffle and the upper clamping plate slide alternately, causing the metal plates to be processed to fall one by one. The two upper clamping plates clamp several metal plates to be processed from both sides, and the two lower baffles slide away from the metal plates, causing a metal plate to fall from between the two lower baffles onto the rotating rollers. The metal plate is then transported to the bottom of the laser cutter for cutting by several rotating rollers.

[0011] As a further improvement to this technical solution, a sliding rod is rotatably installed in the slot, a second through-hole is opened on the upper clamping plate, and a first through-hole is opened on the lower baffle. The first and second inclined grooves are both inclined with opposite inclination angles. The two first and two second inclined grooves on both sides of the metal plate are symmetrically arranged with the center line of the metal plate as the axis of symmetry. A first cylinder is provided on the side of the sliding frame away from the motor. The piston rod of the first cylinder is fixedly connected to the sliding frame. The first cylinder drives the two sliding rods on the sliding frame to slide horizontally through the piston rod. The sliding rods press against the side walls of the first and second inclined grooves. Through the extension and retraction of the piston rod of the first cylinder, the lower baffle and the upper clamping plate slide alternately along the direction of the vertical roller. Through the two lower baffles and two upper clamping plates on both sides of the metal plate, the metal plates fall one by one from the opening of the sliding frame onto the roller.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. In this continuously feeding metal cutting machine tool, several metal plates to be processed are clamped from both sides by two upper clamping plates, and two lower baffles slide away from the metal plates, so that a metal plate falls from between the two lower baffles onto the rotating roller. This design allows the metal plate to be smoothly transferred from the feeding area to the processing area, reducing manual intervention and improving the level of automation and processing efficiency.

[0014] 2. In this continuously feeding metal cutting machine tool, the connecting rod is pulled down by the second cylinder, which drives the slip ring and the slip sleeve to press down the return spring, causing the pin to disengage from the pin hole. This prevents the second connecting shaft from driving the second gear to rotate and stops the rotation of several rollers. This design ensures that the feeding system can stop in time after the metal plate is clamped and fixed, providing a stable processing platform for the laser cutter, thereby improving processing accuracy and production efficiency.

[0015] 3. In this continuously feeding metal cutting machine tool, the connecting rod is pulled down by the second cylinder, which drives the two fixed plates slidably installed below the support plate to clamp and fix the metal plate from both sides. This ensures that the metal plate can be firmly clamped during the cutting process, preventing processing errors caused by vibration or movement, and improving the safety and stability of the processing.

[0037] Example 1

[0038] Please see Figures 1-13 As shown, the purpose of this embodiment is to provide a metal cutting machine tool with sustainable feeding, including a frame assembly 1. The frame assembly 1 provides a stable base for mounting and supporting all other components. Its design ensures the stability of the machine tool under high-speed operation or heavy load conditions, reduces vibration, thereby improving machining accuracy and the service life of the machine tool. A laser cutter 2 is arranged above the frame assembly 1. The laser cutter 2 cuts the metal plate. The laser cutter 2 reduces the use of traditional cutting fluid, reduces the environmental impact, and improves machining speed and cutting quality, achieving a cleaner and more efficient production process. A feeding assembly 3 is arranged on one side of the laser cutter 2. Several metal plates to be processed are placed above the feeding assembly 3. The feeding assembly 3 moves closer to the laser cutter 2 to realize automatic feeding of the metal plates. This not only improves feeding efficiency and reduces manual operation, but also reduces safety risks during operation. The frame assembly 1 transports the metal plates to the area below the laser cutter 2. A clutch device 4 is arranged on the side of the frame assembly 1 away from the feeding assembly 3. The clutch device 4 drives the frame assembly 1, causing the frame assembly 1 to transport the metal plate. The precise control of the clutch device 4 ensures the smooth movement of the metal plate during the transport process, reducing damage to the plate and improving processing efficiency and machine tool response speed. A clamping assembly 5 is installed below the laser cutter 2. The clamping assembly 5 slides downward and clamps the metal plate below the laser cutter 2 from both sides. After the metal plate reaches the designated position, the clamping assembly 5 slides downward and clamps the metal plate from both sides to fix its position. This clamping method ensures the stability of the metal plate during the cutting process, prevents the processing accuracy from being affected by the movement or vibration of the plate, and also protects the safety of the operator. When the clamping assembly 5 slides downward, it drives the clutch device 4 to slide downward, so that the clutch device 4 no longer drives the frame assembly 1 to rotate, thus fixing the position of the metal plate below the laser cutter 2. This linkage mechanism ensures that the machine tool's feeding system can stop in time after the metal plate is fixed, providing a stable processing platform for the laser cutter 2, thereby improving processing accuracy and production efficiency.

[0039] The frame assembly 1 includes a placement frame 11 on which several rollers 12 are rotatably mounted. These rollers 12 are connected by belts to form a continuous conveying system. This design allows the metal sheet to move smoothly inside the machine tool, reducing friction and damage during conveying and improving the continuity and efficiency of the processing. One end of each roller 12 is fixedly fitted with a first helical gear 13. This design allows the roller 12 to transmit power to other rollers 12 via belts when it rotates, achieving continuous conveying of the metal sheet. A first connecting shaft 14 is located below the first helical gear 13. The top end of the first connecting shaft 14 meshes with the first helical gear 13 via a second helical gear 142. When the first connecting shaft 14 rotates, it drives the several rollers 12 to rotate via the first helical gear 13. The rotating rollers 12 transport the metal sheet. This design ensures effective power transmission, allowing the metal sheet to move at a constant speed, improving processing accuracy and stability, and reducing material waste caused by speed fluctuations.

[0040] The clutch device 4 includes a motor 41 fixedly mounted on one side of the placement frame 11. The motor 41's shaft is fixedly connected to a second connecting shaft 42, allowing the motor 41 to directly transmit power to the second connecting shaft 42. This improves power transmission efficiency, reduces energy loss, and facilitates maintenance and replacement of the motor 41, enhancing the machine tool's reliability and maintainability. A second gear 43 is rotatably mounted on the second connecting shaft 42. This design allows the second connecting shaft 42 to transmit power to other components via the second gear 43 during rotation. This gear transmission method not only improves power transmission efficiency but also reduces maintenance costs and failure rates, while also reducing noise and vibration, thus improving the working environment. A first gear 141 is fixedly mounted below the second helical gear 142, and the first gear 141 is in contact with the second gear 43. The meshing ensures that power can be smoothly transmitted from the second connecting shaft 42 to the first gear 141, achieving efficient power transmission. Through precise gear meshing, the machine tool can achieve precise speed control and synchronization, ensuring the processing accuracy of the metal sheet. The motor 41 drives the second connecting shaft 42 to rotate through the rotating shaft. The second connecting shaft 42 drives the first gear 141 to rotate through the second gear 43. The meshing of the second helical gear 142 and the first helical gear 13 drives several rotating rollers 12 to rotate. This design makes the conveying of the metal sheet inside the machine tool more stable and precise, reduces the offset and vibration of the sheet during the conveying process, and improves the processing quality. At the same time, this power transmission method also reduces energy consumption because the direct drive of the rotating rollers 12 reduces energy loss in intermediate links, achieving more efficient energy utilization.

[0041] A sliding sleeve 44 is slidably fitted below the second gear 43. Several pins 431 are located below the second gear 43, and several pin holes are formed above the sliding sleeve 44. The pins 431 are inserted into these pin holes, causing the sliding sleeve 44 to drive the second gear 43 to rotate. This insertion method ensures that the sliding sleeve 44 effectively drives the second gear 43 to rotate, guaranteeing stable power transmission. This design not only improves the reliability of the transmission system but also reduces power loss caused by component gaps, thereby increasing the machine tool's working efficiency. A return spring 45 is fitted below the sliding sleeve 44, which pushes the sliding sleeve 44 upwards. This mechanism ensures that the pin 431 remains in the pin hole, guaranteeing the stability of the sliding sleeve 44 during operation. It also provides the necessary elasticity, allowing the system to adjust quickly and maintain smooth operation when the load changes. The power of the motor 41 is transmitted to the first connecting shaft 14 through the sliding sleeve 44 and the second gear 43, driving several rollers 12 to rotate. This power transmission method ensures that the metal plate is transported from the side of the placement frame 11 away from the motor 41 to the side closer to the motor 41, achieving efficient transport of the metal plate. This not only improves processing efficiency but also reduces material loss during transportation.

[0042] The clamping assembly 5 includes a connecting rod 52 that slides up and down below the rotating roller 12. A slip ring 441 is fixedly connected to one end of the connecting rod 52 near the motor 41. The slip ring 441 rotatably engages with the outside of the sliding sleeve 44. This engagement allows the sliding sleeve 44 to slide up and down on the second connecting shaft 42 under the drive of the slip ring 441, achieving precise control of the clamping assembly 5, ensuring stable clamping of the metal sheet during processing, and improving processing safety and reliability. The connecting rod 52 drives the sliding sleeve 44 to slide up and down on the second connecting shaft 42 via the slip ring 441, causing the pin 431 to insert into or disengage from the pin hole, thus achieving… Precise control of the second gear 43 controls the rotation of the roller 12, improving the machine tool's response speed and processing efficiency. Several splines are provided on the side wall of the second connecting shaft 42, and several spline grooves are provided on the side wall of the sliding sleeve 44. The sliding sleeve 44 slides on the second connecting shaft 42 or rotates with the second connecting shaft 42 through the spline grooves. This spline connection provides a stable and flexible transmission mechanism, enabling the sliding sleeve 44 to slide smoothly on the second connecting shaft 42 while maintaining synchronous rotation with the second connecting shaft 42, ensuring the continuity and stability of power transmission, and improving the machine tool's working efficiency and processing accuracy.

[0043] A support plate 111 is fixedly installed on the placement frame 11 between several rotating rollers 12. When the metal plate slides onto the support plate 111, it stops sliding. This design ensures that the metal plate can accurately stop after reaching the predetermined position, providing stable support for subsequent cutting processing. It also reduces processing errors and material waste caused by the sliding of the metal plate. The laser cutter 2 is fixedly installed above the support plate 111. The rotating rollers 12 cut the metal plate above the support plate 111, ensuring the stability and accuracy of the laser cutter 2 during the processing. This design improves processing efficiency and finished product quality. Two fixing plates 54 are slidably installed below the support plate 111. The fixing plates 54 clamp and fix the metal plate from both sides, ensuring the metal plate is firmly held during cutting and preventing processing errors caused by vibration or movement. This enhances processing safety and stability. A hinge rod 53 is hinged below the fixing plate 54. A hinge seat 521 is fixedly connected above the end of the connecting rod 52 away from the fixing plate 54. The end of the hinge rod 53 away from the fixing plate 54 is hinged to the connecting rod 52. The hinge rod 53 is hinged to both ends of the hinge seat 521. This hinge structure allows the fixed plate 54 to flexibly clamp and release the metal plate, improving the response speed and ease of operation of the clamping assembly 5. A second cylinder 51 is provided below the middle section of the connecting rod 52. The piston rod of the second cylinder 51 is connected to the connecting rod 52. The connecting rod 52 is pulled downward by the piston rod, causing it to slide downward. The hinge seat 521 pulls the two hinge rods 53 downward, causing the two fixed plates 54 to move closer to the metal plate on the support plate 111. The cylinder-driven method enables the clamping assembly 5 to move quickly, improving processing efficiency and the degree of automation. At the same time, the downward sliding connecting rod 52 drives the sliding sleeve 44 to press down the return spring 45 through the slip ring 441, causing the pin 431 to disengage from the pin hole, so that the second connecting shaft 42 no longer drives the second gear 43 to rotate, and the several rotating rollers 12 stop rotating. This design ensures that the feeding system can stop in time after the metal plate is clamped and fixed, providing a stable processing platform for the laser cutter 2, thereby improving processing accuracy and production efficiency.

[0044] The feeding assembly 3 includes a sliding frame 32. The side of the sliding frame 32 closest to the motor 41 has an opening. Several metal sheets to be processed are placed between the openings of the sliding frame 32, allowing the metal sheets to be processed to be placed orderly in the feeding area of ​​the machine tool. This facilitates the automated feeding process, improving processing efficiency and ease of operation. Two slots are provided on the side of the opening closest to the motor 41, respectively positioned on both sides of the metal sheet. An upper clamping plate 34 and a lower baffle plate 33 are sequentially arranged in the slots. This structural design allows the upper clamping plate 34 and the lower baffle plate 33 to slide alternately, controlling the movement and positioning of the metal sheet. This ensures the stability of the metal sheet during processing, reduces processing errors caused by sheet movement or vibration, and improves efficiency. To ensure processing safety and reliability, the lower baffle 33 and the upper clamping plate 34 slide alternately, causing the metal plates to be processed to fall one by one. The two upper clamping plates 34 clamp several metal plates to be processed from both sides, and the two lower baffles 33 slide away from the metal plates, causing a metal plate to fall from between the two lower baffles 33 onto the rotating roller 12. This design allows the metal plate to be smoothly transferred from the feeding area to the processing area, reducing manual intervention and improving the level of automation and processing efficiency. The metal plate is transported to the bottom of the laser cutter 2 for cutting by several rotating rollers 12. This continuous transportation method not only improves the processing efficiency of metal plates, but also reduces damage to the plates during processing and improves the yield of products.

[0045] A sliding rod 321 is rotatably installed in the slot. This design allows the sliding rod 321 to rotate freely in the slot, reducing friction of the metal plate during sliding and ensuring that the metal plate can move smoothly in the feeding assembly 3, improving the smoothness and efficiency of the feeding process. A through second inclined groove 341 is opened on the upper clamping plate 34, and a through first inclined groove 331 is opened on the lower baffle 33. Both the first inclined groove 331 and the second inclined groove 341 are set to be inclined with opposite inclination angles. The two first inclined grooves 331 and the two second inclined grooves 341 on both sides of the metal plate are symmetrically arranged with the center line of the metal plate as the axis of symmetry. This symmetrical inclined groove design ensures that the metal plate can move smoothly when falling. The metal plate slides smoothly during the process, reducing the possibility of displacement or jamming during the fall, thus improving the accuracy and reliability of the feeding. A first cylinder 31 is installed on the side of the sliding frame 32 away from the motor 41. The piston rod of the first cylinder 31 is fixedly connected to the sliding frame 32. The first cylinder 31 drives the two sliding rods 321 on the sliding frame 32 to slide horizontally through the piston rod, causing the sliding rods 321 to press against the side walls of the first inclined groove 331 and the second inclined groove 341. This pressing action allows the upper clamping plate 34 and the lower baffle 33 to slide along the inclined groove, realizing the clamping and release of the metal plate. This design makes the metal plate feeding process more automated. This reduces manual operation and improves production efficiency and safety. When the telescopic rod approaches the motor 41, it drives the two upper clamping plates 34 to press against the side wall of the metal plate, causing the two lower baffles 33 to slide away from the metal plate. When the telescopic rod approaches the first cylinder 31, it drives the two upper clamping plates 34 to slide away from the metal plate. Under the action of gravity, the metal plate falls downwards, and the two lower baffles 33 slide from the bottom of the metal plate towards the metal plate, supporting the metal plate above. This alternating sliding action allows the metal plates to fall onto the rotating roller 12 one by one, realizing continuous feeding of the metal plates and improving processing efficiency. The telescopic rod then moves towards the motor again. 41 approaches, causing the two upper clamping plates 34 to press against the side wall of the metal plate, while simultaneously causing the two lower baffles 33 to slide away from the metal plate. At this time, the lowest metal plate falls onto the rotating roller 12. Through the extension and retraction of the piston rod of the first cylinder 31, the lower baffles 33 and the upper clamping plates 34 slide alternately along the direction perpendicular to the rotating roller 12. Through the two lower baffles 33 and the two upper clamping plates 34 on both sides of the metal plate, the metal plates fall one by one from the opening of the sliding frame 32 onto the rotating roller 12. This continuous falling mechanism ensures that the metal plates can be continuously transported to the laser cutter 2 for cutting, improving the continuity and efficiency of the overall processing flow.

[0046] In this embodiment, the metal sheet to be processed is placed between the openings of the sliding frame 32 of the feeding assembly 3 to ensure correct placement for subsequent automated feeding. The extension rod of the extended first cylinder 31 supports the metal sheet from the bottom via two lower baffles 33. The retracting extension rod of the first cylinder 31 clamps the metal sheet from both sides via upper clamping plates 34, ensuring stability during processing. The piston rod of the first cylinder 31 drives the sliding rod 321 on the sliding frame 32 to slide horizontally, pressing against the sidewalls of the first and second inclined grooves 331 and 341. The movement of the sliding rod 321 causes the upper clamping plate 34 to press against the sidewalls of the metal sheet, causing the lower baffles 33 to slide away from the metal sheet, resulting in the metal sheets falling one by one onto the rotating roller 12. The rotating roller 12 transports the metal sheet from one side of the placement frame 11 to below the laser cutter 2 for cutting. During the movement, the clutch device 4 controls the power transmission to ensure that the sheet metal accurately reaches the cutting position. The laser cutter 2 precisely cuts the metal sheet metal located above the support plate 111. The piston rod of the second cylinder 51 pulls the connecting rod 52 downward, causing the hinge rod 53 and the fixed plate 54 to move closer to the metal sheet for clamping, ensuring the stability of the sheet metal during the cutting process. At the same time, the piston rod of the second cylinder 51 drives the sliding sleeve 44 through the connecting rod 52 to squeeze the return spring 45, causing the pin 431 to disengage from the pin hole, stopping the power transmission to the rotating roller 12, and stopping the feeding. This design ensures that the feeding system can stop in time after the metal sheet metal is clamped and fixed, providing a stable processing platform for the laser cutter 2, thereby improving processing accuracy and production efficiency. Through the cycle of the above steps, the continuous feeding, clamping, cutting and releasing of the metal sheet metal is realized, improving processing efficiency and production capacity.
