[0037] Example 1

[0038] See also Figure 1-Figure 13 As shown, the purpose of this embodiment is to provide a metal cutting machine tool with sustainable feeding, including a frame component 1. The frame component 1 provides a stable base for installing and supporting all other components. Its design ensures the stability of the machine tool under high-speed operation or heavy-load conditions, reduces vibration, and thus improves processing accuracy and the service life of the machine tool. A laser cutter 2 is arranged above the frame component 1. The laser cutter 2 cuts the metal plate. The laser cutter 2 reduces the use of traditional cutting fluid and reduces the impact on the environment. At the same time, it improves the processing speed and cutting quality to achieve a cleaner and more efficient production process. A loading component 3 is arranged on one side of the laser cutter 2. Several metal plates to be processed are placed above the loading component 3. The loading component 3 approaches the laser cutter 2 to realize automatic loading of the metal plates, which not only improves the loading efficiency and reduces manual operation, but also reduces the safety risks during operation. The frame component 1 transports the metal plate to the bottom of the laser cutter 2, and a clutch device 4 is arranged on the side of the frame component 1 away from the loading component 3. The clutch device 4 drives the frame assembly 1 to transport the metal plate. The precise control of the clutch device 4 can ensure the smooth movement of the metal plate during the transportation process, reduce the damage of the plate, and improve the processing efficiency and the response speed of the machine tool. A clamping assembly 5 is arranged 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 specified 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, so that the position of the metal plate below the laser cutter 2 is fixed. This linkage mechanism ensures that after the metal plate is fixed, the feeding system of the machine tool can stop in time, providing a stable processing platform for the laser cutter 2, thereby improving the processing accuracy and production efficiency.

[0039] The frame assembly 1 includes a placing frame 11, on which a plurality of rollers 12 are rotatably mounted. The plurality of rollers 12 are connected by belts to form a continuous conveying system. Such a design enables the metal sheet to move smoothly inside the machine tool, reduces the friction and damage of the sheet during the conveying process, and improves the continuity and efficiency of the processing process. A first bevel gear 13 is fixedly sleeved at one end of a roller 12. Such a design allows the roller 12 to transmit power to other rollers 12 through a belt when rotating, thereby realizing continuous conveying of the metal sheet. A first connecting shaft 14 is arranged below the first bevel gear 13, and the top end of the first connecting shaft 14 is meshed with the first bevel gear 13 through a second bevel gear 142. When the first connecting shaft 14 rotates, the plurality of rollers 12 are driven to rotate through the first bevel gear 13, and the plurality of rotating rollers 12 transport the metal sheet. Such a design ensures the effective transmission of power, enables the metal sheet to move at a constant speed, improves the processing accuracy and stability, and also reduces the 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, and the rotating shaft of the motor 41 is fixedly connected to the second connecting shaft 42, so that the motor 41 can directly transmit power to the second connecting shaft 42, thereby improving the efficiency of power transmission and reducing energy loss. It is also convenient for maintenance and replacement of the motor 41, thereby improving the reliability and maintainability of the machine tool. A second gear 43 is rotatably sleeved on the second connecting shaft 42. This design allows the second connecting shaft 42 to transmit power to other components through the second gear 43 when rotating. This gear transmission method not only improves the efficiency of power transmission, but also reduces maintenance costs and failure rates, while also reducing noise and vibration, thereby improving the working environment. A first gear 141 is fixedly mounted below the second bevel gear 142, and the first gear 141 is coupled to the second gear 43. The meshing ensures that power can be smoothly transmitted from the second connecting shaft 42 to the first gear 141, realizing 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, and the second connecting shaft 42 drives the first gear 141 to rotate through the second gear 43. The second bevel gear 142 and the first bevel gear 13 are meshed to drive several rollers 12 to rotate. This design makes the transportation of metal sheets inside the machine tool more stable and precise, reduces the displacement and vibration of the sheets during transportation, and improves the processing quality. At the same time, this power transmission method also reduces energy consumption, because the direct drive of the roller 12 reduces the energy loss in the intermediate links, and realizes more efficient energy utilization.

[0041] A sliding sleeve 44 is provided below the second gear 43. A plurality of pins 431 are provided below the second gear 43. A plurality of pin holes are provided above the sliding sleeve 44. The pins 431 are inserted into the pin holes so that the sliding sleeve 44 drives the second gear 43 to rotate. Through this insertion method, the sliding sleeve 44 can effectively drive the second gear 43 to rotate, thereby ensuring the stable transmission of power. This design not only improves the reliability of the transmission system, but also reduces the power loss caused by the gap between components, thereby improving the working efficiency of the machine tool. A reset spring 45 is provided below the sliding sleeve 44, which pushes the sliding sleeve 44 upward. The pin 431 is always kept in the pin hole. This mechanism ensures the stability of the sleeve 44 in the working state and provides the necessary elasticity so that the system can adjust quickly when the load changes to maintain smooth operation. The power of the motor 41 is transmitted to the first connecting shaft 14 through the 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 close to the motor 41, thereby realizing efficient transportation of the metal plate, which not only improves the processing efficiency, but also reduces the loss of materials during transportation.

[0042] The clamping assembly 5 includes a connecting rod 52 that is arranged below the roller 12 and slides up and down. The end of the connecting rod 52 close to the motor 41 is fixedly connected to a slip ring 441. The slip ring 441 is rotatably engaged with the outside of the sliding sleeve 44. This engagement mode allows the sliding sleeve 44 to slide up and down on the second connecting shaft 42 driven by the slip ring 441, thereby achieving precise control of the clamping assembly 5, ensuring stable clamping of the metal sheet during processing, and improving the safety and reliability of processing. The connecting rod 52 drives the sliding sleeve 44 to slide up and down on the second connecting shaft 42 through the slip ring 441, so that the pin 431 is inserted into the pin hole or detached from the pin hole, thereby achieving The rotation of the roller 12 is controlled precisely by the second gear 43, thereby improving the response speed and processing efficiency of the machine tool. A plurality of splines are arranged on the side wall of the second connecting shaft 42, and a plurality of spline grooves are opened on the side wall of the sleeve 44. The sleeve 44 slides on the second connecting shaft 42 or rotates with the second connecting shaft 42 through the spline grooves. This spline connection method provides a stable and flexible transmission mechanism, so that the sleeve 44 can slide smoothly on the second connecting shaft 42 while maintaining synchronous rotation with the second connecting shaft 42, thereby ensuring the continuity and stability of power transmission and improving the working efficiency and processing accuracy of the machine tool.

[0043] A support plate 111 is fixedly mounted on the placement frame 11 between the rollers 12. The metal plate stops sliding when it slides onto the support plate 111. This design ensures that the metal plate can stop accurately after reaching the predetermined position, providing stable support for subsequent cutting processing, while also reducing processing errors and material waste caused by the sliding of the metal plate. The laser cutter 2 is fixedly mounted above the support plate 111, and the rollers 12 cut the metal plate above the support plate 111, ensuring the stability and accuracy of the laser cutter 2 during the processing. The processing efficiency and the quality of the finished product are improved. Two fixing plates 54 are slidably installed under the supporting plate 111. The fixing plates 54 clamp and fix the metal plate from both sides, so 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. A hinge rod 53 is hinged at the bottom of the fixing plate 54, and 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 two The hinged rod 53 is hinged at both ends of the hinged seat 521. This hinged structure enables the fixed plate 54 to flexibly clamp and release the metal plate, thereby improving the response speed and operation convenience of the clamping assembly 5. A second cylinder 51 is arranged 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 slides downward by pulling the connecting rod 52 downward through the piston rod, and the two hinged rods 53 slide downward through the hinged seat 521, driving the two fixed plates 54 to move closer to the metal plate on the supporting plate 111. The cylinder drive mode realizes the rapid movement of the clamping assembly 5, improves the processing efficiency and the degree of automation of the operation; at the same time, the connecting rod 52 sliding downward drives the sliding sleeve 44 through the slip ring 441 to squeeze the reset spring 45 downward, so that the pin 431 is disengaged from the pin hole, so that the second connecting shaft 42 no longer drives the second gear 43 to rotate, and the plurality of 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 the processing accuracy and production efficiency.

[0044] The loading assembly 3 includes a sliding frame 32, and one side of the sliding frame 32 close to the motor 41 is set as an opening. Several metals to be processed are placed between the openings of the sliding frame 32, so that the metal plates to be processed can be placed in the loading area of ​​the machine tool in an orderly manner, which is convenient for the automated loading process, improves the processing efficiency and the convenience of operation, and the opening is provided with two notches on the side close to the motor 41. The two notches are respectively arranged on both sides of the metal plate, and the upper clamping plate 34 and the lower baffle plate 33 are sequentially arranged in the upper and lower grooves. This structural design allows the upper clamping plate 34 and the lower baffle plate 33 to slide alternately, control the movement and positioning of the metal plate, ensure the stability of the metal plate during the processing, reduce the processing error caused by the movement or vibration of the plate, and improve In order to ensure the safety and reliability of processing, the lower baffle 33 and the upper clamping plate 34 slide alternately, so that the metal plates to be processed fall one by one, and the two upper clamping plates 34 clamp several metal plates to be processed from both sides, and the two lower baffles 33 slide in the direction away from the metal plates, so that a metal plate falls from between the two lower baffles 33 onto the roller 12. This design allows the metal plate to be smoothly transferred from the loading area to the processing area, reduces manual intervention, and improves the level of automation and processing efficiency. The metal plate is transported to the bottom of the laser cutter 2 for cutting through several rollers 12. This continuous transportation method not only improves the processing efficiency of the metal plate, but also reduces the damage to the plate during the processing, thereby improving the product yield.

[0045] A slide bar 321 is rotatably installed in the slot. This design allows the slide bar 321 to rotate freely in the slot, reducing the friction of the metal plate during the sliding process, ensuring that the metal plate can move smoothly in the loading assembly 3, and improving the fluency and efficiency of the loading process. A second inclined groove 341 is provided on the upper clamping plate 34, and a first inclined groove 331 is provided on the lower baffle plate 33. The first inclined groove 331 and the second inclined groove 341 are both arranged to be inclined and have 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 symmetry axis. This symmetrical inclined groove design allows the metal plate to be dropped when it is dropped. The first cylinder 31 is arranged on the side of the sliding frame 32 away from the motor 41, and the piston rod of the first cylinder 31 is fixedly connected to the sliding frame 32. The first cylinder 31 drives the two slide bars 321 on the sliding frame 32 to slide horizontally through the piston rod, and drives the slide bars 321 to squeeze the side walls of the first inclined groove 331 and the second inclined groove 341. This squeezing action enables the upper clamping plate 34 and the lower baffle plate 33 to slide along the inclined groove to achieve the clamping and release of the metal plate. This design makes the feeding process of the metal plate more automated. , reducing manual operations, improving production efficiency and safety. When the telescopic rod approaches the motor 41, it drives the two upper clamping plates 34 to squeeze the side walls of the metal plate, so that the two lower baffles 33 slide in the direction away from the metal plate; when the telescopic rod approaches the first cylinder 31, it drives the two upper clamping plates 34 to slide in the direction away from the metal plate. Under the action of gravity, the metal plate falls downward, and the two lower baffles 33 slide from the bottom of the metal plate to the direction close to the metal plate to support the upper metal plate. 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 moves toward the motor again 41 approaches, driving the two upper clamps 34 to squeeze the side walls of the metal plate, and at the same time making the two lower baffles 33 slide in the direction away from the metal plate. At this time, the lowest metal plate falls onto the rotating roller 12, and the piston rod of the first cylinder 31 is extended and retracted, so that the lower baffles 33 and the upper clamps 34 slide alternately in the direction perpendicular to the rotating roller 12, and the metal plates are dropped one by one from the opening of the sliding frame 32 onto the rotating roller 12 through the two lower baffles 33 and the two upper clamps 34 on both sides of the metal plate. This continuous dropping mechanism ensures that the metal plate can be continuously transported to the bottom of the laser cutter 2 for cutting, thereby improving the continuity and efficiency of the overall processing flow.

[0046] When this embodiment is used, the metal sheet to be processed is placed between the openings of the sliding frame 32 of the loading assembly 3 to ensure that the metal sheet is placed correctly for the subsequent automated loading process. The telescopic rod of the extended first cylinder 31 supports the metal sheet from the bottom with two lower baffles 33, and the upper clamping plate 34 of the telescopic rod of the retracted first cylinder 31 clamps the metal sheet from both sides to ensure the stability of the sheet during processing. The piston rod of the first cylinder 31 drives the slide bar 321 on the sliding frame 32 to slide horizontally, squeezing the side walls of the first chute 331 and the second chute 341 of the chute. The movement of the slide bar 321 drives the upper clamping plate 34 to squeeze the side wall of the metal sheet, so that the lower baffle 33 slides away from the metal sheet, causing the metal sheets to fall onto the roller 12 one by one; the roller 12 transports the metal sheet from one side of the placement frame 11 to the bottom of the laser cutter 2 for cutting, and the metal sheet is cut on the roller 12. During the movement on the plate, the clutch device 4 controls the power transmission to ensure that the plate reaches the cutting position accurately, and the laser cutter 2 accurately cuts the metal plate located above the supporting plate 111. The piston rod of the second cylinder 51 of the cylinder pulls the connecting rod 52 to slide downward, driving the hinged rod 53 and the fixed plate 54 to approach the metal plate for clamping, thereby ensuring the stability of the plate 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 reset spring 45, so that the pin 431 is disengaged from the pin hole, and the power transmission to the roller 12 is stopped, so that the feeding is stopped. 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 the processing accuracy and production efficiency. Through the cycle of the above steps, the continuous loading, clamping, cutting and releasing of the metal plate are realized, thereby improving the processing efficiency and production capacity.
