Description

Technical Field

[0001] This invention belongs to the field of door and window processing technology, specifically relating to a multi-angle synchronous cutting device for door and window processing. Background Technology

[0002] During the installation and production of metal doors and windows, cutting machines are usually required to cut the door and window profiles. The cutting equipment includes laser cutters and saw blade cutters.

[0003] For example, a metal door and window profile cutting device with angle adjustment function (publication number: CN119035800A) includes a machine body. A limiting component is installed on the outer wall of the machine body, a fixing component is installed on the upper side of the machine body, a support mesh component and an auxiliary debris removal component are installed in the middle of the machine body, a sliding seat is slidably connected to the outer wall of the machine body, a laser cutter is installed above the support mesh component, and an air blowing mechanism and a lubrication mechanism are installed inside the sliding seat. This metal door and window profile cutting device with angle adjustment function, through the use of the sliding seat, air blowing mechanism, and trapezoidal block two, allows the sliding seat to blow dust and debris from the surface of the machine body onto the support mesh body during sliding, reducing the contact between the sliding seat and dust and debris during sliding and ensuring that the device can continuously cut metal door and window profiles at multiple angles.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it is known that the aforementioned equipment only supports conventional vertical angle cutting. For special angles required for some doors and windows (such as 30°, 60°, 120°, etc.), manual adjustment or replacement of special fixtures is required, which is cumbersome and has low angle accuracy. Furthermore, laser cutters can only achieve single-dimensional angle adjustment and cannot take into account the combined angle adjustment of horizontal and vertical directions, making it difficult to adapt to complex door and window splicing requirements. Therefore, we propose a multi-angle synchronous cutting device for door and window processing to solve the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-angle synchronous cutting device for door and window processing.

[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. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. 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] This invention provides, for example Figure 1-7 The multi-angle synchronous cutting equipment for door and window processing shown includes a frame 1, a fixing component 2, a sliding plate 3, a multi-angle moving mechanism, a groove 8, a drive component 9, a chip collection chamber 10, a support net 11, a chip discharge door 12, and a dust collection component 13; like Figure 1 As shown, fixing components 2 are installed on the top of both ends of the frame 1 to fix the ends of the doors and windows. Specifically, the frame 1 is welded from high-strength alloy steel and has anti-slip and shock-absorbing pads installed at the bottom, which improves the overall stability of the equipment and avoids vibration and displacement during the cutting process; the installation positions of the two sets of fixing components 2 can fix doors and windows of different lengths and are also compatible with door and window profiles of different specifications, thereby expanding the applicability of the equipment and ensuring that the fixing force at both ends of the doors and windows is uniform. In addition, the two sets of sliding plates 3 are symmetrically slidably installed on the two side walls of the frame 1; the sliding surfaces are coated with wear-resistant grease, which reduces sliding friction resistance and ensures the moving accuracy of the sliding plates 3. Among them, the multi-angle moving mechanism is installed on the top of the two sets of sliding plates 3; by setting the multi-angle moving mechanism to integrate the functions of horizontal movement, lifting and angle adjustment, and the modular design of each component, the effect of simplifying the structural layout and facilitating later maintenance and repair is achieved. like Figure 3 and 4 As shown, the multi-angle moving mechanism includes a transverse moving component 4, a lifting component 5, a cutting angle adjusting component 6, and a laser cutter 7; The lifting assembly 5, the cutting angle adjustment assembly 6, and the laser cutter 7 are all provided in two sets. The two sets of lifting assemblies 5 are respectively installed on the two moving ends of the transverse assembly 4. The laser cutter 7 is installed on the moving end of the lifting assembly 5 through the cutting angle adjustment assembly 6. The two moving ends of the transverse assembly 4 move synchronously, respectively driving the laser cutter 7 on the two sets of lifting assemblies 5 to adjust its position according to the width of the door and window, and adjusting the cutting angle of the laser cutter 7 through the cutting angle adjustment assembly 6. Specifically, by setting up two sets of laser cutters 7 that can be independently controlled and operate synchronously, the angle adjustment range covers 0-180°, achieving the effect of meeting different angle cutting needs and improving processing efficiency; like Figure 1 As shown, the side walls on both sides of the frame 1 are symmetrically opened with two sets of grooves 8, each of which is equipped with a drive assembly 9 that drives the two sets of sliding plates 3. Specifically, groove 8 provides installation space for drive component 9; like Figure 2 As shown, the chip collection chamber 10 is located inside the frame 1, with an inclined structure at the bottom to facilitate chip removal. A chip removal door 12 is hinged to one side, and a support net 11 is fixedly installed on the top. Specifically, by setting the support mesh 11 to be made of hollow stainless steel with a hole diameter of 5mm, and the chip discharge door 12 to be equipped with a sealing buckle, the support mesh 11 can filter and isolate large chips, while allowing small chips to fall smoothly into the chip collection chamber 10, and at the same time ensuring the sealing effect of the chip collection chamber 10. like Figure 1 , 2 As shown in Figure 6, the dust collection component 13 is installed in the reserved cavity at one end of the frame 1 to cooperate with the negative pressure adsorption of dust and debris generated during door and window cutting in the chip collection cavity 10. Specifically, by setting the dust suction component 13 and the chip collection chamber 10 to form a fully enclosed negative pressure circuit, the effect of efficiently adsorbing cutting dust and fine chips and improving the processing environment is achieved. like Figure 3 and 4As shown, the transverse component 4 in this embodiment includes a fixed housing 41, a bidirectional threaded rod 42, a transverse motor 43, and a sliding block 44; The fixed housing 41 is fixedly installed on the top of the two sets of sliding plates 3 (e.g., by bolts or welding), the bidirectional threaded rod 42 is rotatably installed inside the fixed housing 41 (e.g., by bearings), the transverse motor 43 is installed at one end of the fixed housing 41 and is fixedly connected to one end of the bidirectional threaded rod 42 by a coupling, and the outer walls of both ends of the bidirectional threaded rod 42 are threaded with sliding blocks 44, and the two sets of lifting components 5 are respectively installed on the top of the two sets of sliding blocks 44; Specifically, the fixed housing 41 has a lubricating grease storage groove inside, and the bidirectional threaded rod 42 adopts a trapezoidal thread structure, which reduces thread wear and ensures the stability of the transverse transmission. The transverse motor 43 adopts a servo motor, and the sliding block 44 and the inner wall of the fixed housing 41 adopt a clearance fit, which achieves the effect of high-precision synchronous movement of the sliding block 44 and controlling the cutting position error in the width direction of the door and window.

[0021] like Figure 3 and 4 As shown, the lifting assembly 5 in this embodiment includes an assembly frame 51, a first threaded rod 52, a lifting motor 53, and a lifting block 54; The assembly frame 51 is fixedly installed on the top of the sliding block 44. The first threaded rod 52 is rotatably installed on one side of the assembly frame 51 through the support block. The top of the first threaded rod 52 passes through the assembly frame 51 and is fixedly connected to the lifting motor 53 through a coupling. The lifting block 54 is threadedly installed on the outer wall of the first threaded rod 52. The cutting angle adjustment component 6 is fixedly installed on one side wall of the lifting block 54. Specifically, the assembly frame 51 adopts an integrated aluminum alloy structure, and the surface of the first threaded rod 52 is hardened to improve the structural strength of the lifting assembly 5 and enhance the wear resistance of the threaded rod. The lifting motor 53 adopts a stepper motor and is equipped with a position encoder. Wear-resistant nut sleeves are installed in the threaded holes of the lifting block 54 to achieve precise control of the lifting height.

[0022] In addition, such as Figure 4 As shown, it also includes two sets of guide rails 55; the two sets of guide rails 55 are symmetrically fixedly installed on one side surface of the assembly frame 51 and located on both sides of the first threaded rod 52. A guide groove corresponding to the two sets of guide rails 55 is opened on one side of the lifting block 54, and the outer wall of the guide rail 55 is slidably connected to the inner wall of the guide groove. Specifically, the guide rail 55 adopts a ball bearing guide rail with chrome plating, which further improves the smoothness of the movement of the lifting block 54 and reduces the shaking during the lifting process. The fit clearance between the guide rail 55 and the guide groove is 0.02mm. Wear-resistant lining is pasted on the inner wall of the guide groove to prevent the lifting block 54 from jamming during lifting and to ensure the guiding accuracy.

[0023] like Figure 5 As shown, the cutting angle adjustment component 6 in this embodiment includes a first fixing frame 61, a first adjustment motor 62, a second fixing frame 64, a rotating shaft 65, a large gear 66, a second adjustment motor 67, and a small gear 68; The lifting block 54 is fixedly mounted on one side of a first fixed frame 61. The first adjusting motor 62 is fixedly mounted on the inner surface of the first fixed frame 61 via a reducer. The output end of the reducer passes through the first fixed frame 61 and is fixedly connected to the top of the second fixed frame 64. The rotating shaft 65 is rotatably mounted on one side wall of the second fixed frame 64 (such as a bearing installation). One end of the rotating shaft 65 passes through the second fixed frame 64 and is fixedly mounted on one side of the laser cutter 7 via a mounting plate. A large gear 66 is fixedly sleeved on the outer wall of the other end of the rotating shaft 65. A small gear 68 meshes with the top side of the large gear 66. The second adjusting motor 67 is fixedly mounted inside the second fixed frame 64 via a bracket. The output end of the second adjusting motor 67 is connected to a reducer. The output end of the reducer is fixedly mounted to the small gear 68. Specifically, both the first fixed frame 61 and the second fixed frame 64 adopt a steel plate welded structure, and the gear transmission ratio is set to 3:1, which achieves the effect of improving the rigidity of the angle adjustment component and realizing the effect of fine-tuning the angle; both the first adjustment motor 62 and the second adjustment motor 67 adopt servo motors, equipped with angle encoders, and the reducer reduction ratio is 10:1, which achieves the effect of realizing multi-angle adjustment of the laser cutter 7 in both horizontal and vertical dimensions, with an angle control accuracy of ±0.5°.

[0024] like Figure 5 As shown, it also includes a first turntable bearing 63 and a second turntable bearing 69; The first turntable bearing 63 is fixedly embedded in one side wall of the first fixed frame 61, and the bottom of the first turntable bearing 63 is fixedly connected to the top of the second fixed frame 64. The second turntable bearing 69 is fixedly embedded in the second fixed frame 64 on the outside of the rotating shaft 65, and one side of the second turntable bearing 69 is fixedly connected to the mounting plate on one side of the laser cutter 7. Specifically, the turntable bearing adopts a high-precision crossed roller bearing, which is filled with grease to reduce frictional resistance during angle adjustment and ensure rotational stability. The outer ring of the turntable bearing is interference-fitted with the fixed frame, and the inner ring is rigidly connected to the connecting parts, which enhances the load-bearing capacity of the angle adjustment component and prevents the laser cutter 7 from shifting during operation.

[0025] like Figure 6 As shown, the dust collection assembly 13 in this embodiment includes a dust collection box 131, a three-way pipe 132, a dust collection hood 133, a dust collection fan 134, a filter screen 135, and a dust discharge box 136; The dust collection box 131 is fixedly installed in the reserved cavity at one end of the frame 1 by a bracket. The three-way pipe 132 is fixedly connected to the air inlet of the dust collection box 131. Both ends of the three-way pipe 132 are fixedly connected to the dust suction hood 133 by pipes. Both sets of dust suction hoods 133 are installed on the side wall of the frame 1 through the reserved slots on both sides of the frame 1. The dust suction hood 133 is connected to the inside of the dust collection cavity 10. The air outlet on one side of the dust collection box 131 is fixedly connected to the dust suction fan 134. The air inlet of the dust suction fan 134 is fixedly installed with a filter screen 135. An installation slot is opened on one side of the dust collection box 131. A dust discharge box 136 is inserted into the installation slot. A rubber ring is installed between the dust discharge box 136 and the slot of the installation slot. Specifically, the dust collection box 131 is made of cold-rolled steel plate welded together and the inside is rust-proofed. The three-way pipe 132 is made of PVC material, which improves the sealing of the dust collection component 13 and prevents pipe corrosion. The dust collection hood 133 adopts a trumpet-shaped structure, the filter 135 is a HEPA high-efficiency filter, and the dust discharge box 136 adopts a drawer-type design, which expands the dust collection range, achieves a filtration accuracy of 0.3μm, and facilitates the cleaning of collected debris and dust.

[0026] like Figure 6 As shown, the drive assembly 9 in this embodiment includes a second threaded rod 91, a drive motor 92, and a moving block 93; The second threaded rod 91 is rotatably mounted on one side of the inner wall of the groove 8 (e.g., mounted via a bearing), the drive motor 92 is fixedly connected to the other end of the second threaded rod 91 via a coupling, the moving block 93 is threadedly mounted on the outer wall of the second threaded rod 91, and the side wall of the sliding plate 3 is fixedly connected to one side of the moving block 93. Specifically, the second threaded rod 91 adopts a ball screw structure, and the drive motor 92 is equipped with a brake device, which achieves the effect of improving the moving accuracy of the sliding plate 3 and preventing the sliding plate 3 from moving on its own after power failure; the drive motor 92 adopts a servo motor, and a guide slider is installed between the moving block 93 and the inner wall of the groove 8, which achieves the effect of realizing the precise movement of the sliding plate 3 along the length direction of the frame 1, and the moving speed can be adjusted within the range of 0-50mm / s.

[0027] It is worth noting that the outer wall of the second threaded rod 91 is provided with a telescopic protective cover (not shown in the figure), which is made of a telescopic material and adapted to the length of the threaded rod, and is fitted over the outside of the threaded rod. When the threaded rod drives the related components to move, the protective cover can extend or retract accordingly with the extension or movement of the threaded rod, always tightly wrapping the threaded rod.

[0028] It is worth noting that the two sets of drive motors 92 use the same model of servo motor (such as Panasonic MSMF series), and are equipped with planetary reducers and absolute encoders with the same reduction ratio (10:1), which achieves the effect of ensuring consistent motor output characteristics and uniform position signal acquisition accuracy; the power cables of the two sets of motors are symmetrically routed with shielded wires, and the encoder signals are connected to the dual-axis control interface of the same motion control card (such as Advantech PCIe-1285), which achieves the effect of reducing electromagnetic interference and ensuring signal transmission synchronization; Control logic design The motion control card adopts a "master-slave axis synchronization mode," designating one set of drive motors 92 as the master axis and the other set as the slave axis. The slave axis follows the position and speed signals of the master axis in real time, achieving the effect of completely consistent motion trajectories between the two axes. By adding an "electronic gear ratio calibration" function to the control program, the synchronization coefficient is calculated based on the lead screw lead and the motor encoder resolution (such as a 17-bit encoder). The formula is: electronic gear ratio = (lead screw lead × encoder resolution) / (displacement per revolution of the motor), which achieves the effect of accurately matching mechanical transmission and motor control and eliminating accumulated errors.

[0029] like Figure 7 As shown, the fixing component 2 in this embodiment includes a support plate 21, a concave frame 22, a first cylinder 23, and a pressure plate 24; Among them, the support plate 21 is fixedly installed on the surface of one end of the frame 1, the concave frame 22 is fixedly installed on the top of the support plate 21, and two sets of first cylinders 23 are symmetrically fixedly installed on the top of the concave frame 22. The bottom of the extension and retraction ends of the two sets of first cylinders 23 are fixedly connected to the pressure plate 24 through the concave frame 22. Specifically, the surface of the support plate 21 is covered with anti-slip rubber pads, and the concave frame 22 is welded from channel steel, which enhances the friction when fixing the door and window profiles and improves the structural stability of the fixing component 2. By setting the working pressure of the first cylinder 23 to 0.4-0.6MPa and installing an elastic buffer pad at the bottom of the pressure plate 24, the door and window profiles can be quickly clamped and released, while avoiding excessive clamping force that could damage the surface of the profiles.

[0030] It is worth noting that the two sets of first cylinders 23 use the same model of double-acting cylinder (such as SMC MGPM series), with a cylinder diameter of 50mm and a stroke of 80mm, achieving the effect of ensuring consistent cylinder output force and movement speed; the air inlet and outlet of the two sets of cylinders are connected in parallel to the same air pipeline through a three-way connector, and a pressure regulating valve (adjusting pressure 0.4-0.6MPa) and a flow control valve (adjusting flow 0.2-0.5m³ / min) are installed at the air source end, achieving the effect of ensuring that the air inlet / exhaust pressure and flow of the two cylinders are exactly the same; the two sets of cylinders are controlled by the same solenoid directional valve (such as SMC VF series), with a valve core response time ≤5ms, and the control signal of the solenoid directional valve is triggered by the same PLC output port (such as Q0.0 of Siemens S7-1200), achieving the effect of synchronous issuance of action commands for the two cylinders.

[0031] like Figure 3 As shown, it also includes two sets of centering components 14, which are respectively installed on two sets of sliding plates 3. In this embodiment, the centering component 14 includes a second cylinder 141, an L-shaped plate 142, a rotating roller 143 and a limiting rod 144. The second cylinder 141 is fixedly installed on one side wall of the sliding plate 3. One end of the extension end of the second cylinder 141 passes through the sliding plate 3 and is fixedly connected to an L-shaped plate 142. Several sets of rotating rollers 143 are rotatably installed on one side of the L-shaped plate 142. Limiting rods 144 are slidably inserted into both sides of the sliding plate 3 located on the second cylinder 141. One end of each of the two sets of limiting rods 144 is fixedly connected to one side of the L-shaped plate 142. Specifically, the L-shaped plate 142 is formed by bending steel plate, and the surface of the rotating roller 143 is covered with polyurethane material, which improves the structural strength of the centering component 14 and prevents scratches on the surface of the door and window profiles. Two sets of second cylinders 141 are set synchronously. The second cylinders 141 drive the rotating roller 143 on the L-shaped plate 142 to fit against the door and window, so that the door and window are centered. The limit rod 144 adopts an optical axis and a linear bearing to achieve automatic centering and positioning of the door and window profiles, with the centering error controlled within ±0.2mm, while ensuring the smooth movement of the L-shaped plate 142.

[0032] Working principle: The two ends of the door and window profile to be processed are placed on the support plates 21 of the two sets of fixing components 2; the second cylinder 141 of the centering component 14 is activated, which drives the two sets of L-shaped plates 142 to move inward synchronously. The door and window profile is automatically centered by the rotating roller 143, and the limit rod 144 ensures that the L-shaped plate 142 moves smoothly; after the centering is completed, the first cylinder 23 of the fixing component 2 extends and drives the pressure plate 24 to move downward, pressing and fixing the two ends of the door and window profile to prevent displacement during the cutting process; According to the width requirements of door and window processing, start the transverse motor 43 of the transverse component 4 to drive the bidirectional threaded rod 42 to rotate, so that the two sets of sliding blocks 44 move closer or further away at the same time, and adjust the position of the two sets of laser cutters 7 in the width direction; at the same time, start the drive motor 92 of the drive component 9 to drive the second threaded rod 91 to rotate, and drive the sliding plate 3 to move along the length direction of the frame 1 through the moving block 93, and adjust the cutting position of the laser cutter 7 in the length direction. According to the cutting angle requirements, the first adjustment motor 62 of the cutting angle adjustment component 6 is activated, which drives the second fixed frame 64 to rotate around the first turntable bearing 63 through the reducer, thereby realizing the angle adjustment of the laser cutter 7 in the horizontal dimension; the second adjustment motor 67 is activated, which drives the small gear 68 to rotate through the reducer, meshing and driving the large gear 66 and the rotating shaft 65 to rotate, thereby realizing the angle adjustment of the laser cutter 7 in the vertical dimension. The two sets of adjustment motors work together to achieve arbitrary angle adjustment within the range of 0-180°. The angle encoder provides real-time feedback of position information to ensure adjustment accuracy. Start the lifting motor 53 of the lifting assembly 5 to drive the first threaded rod 52 to rotate, so that the lifting block 54 moves up and down along the guide rail 55, adjust the cutting height of the laser cutter 7, ensure that the laser focus is accurately aligned with the cutting surface, and ensure that the guide rail 55 ensures that the lifting block 54 moves smoothly without shaking. After all positions and angles are adjusted, the laser cutter 7 is started to cut the door and window profiles simultaneously; at the same time, the dust suction fan 134 of the dust suction component 13 is started, and a negative pressure is formed in the dust collection box 131. The dust and debris generated during cutting are adsorbed through the three-way pipe 132 and the dust suction hood 133, so that a certain negative pressure is formed at the bottom of the support net 11, so that the smoke and dust generated during cutting pass through the support net 11 and enter the chip collection chamber 10. The smoke and dust enter the dust suction hood 133, and after being filtered by the filter screen 135, the debris and some dust fall into the dust discharge box 136. Small debris falls into the bottom of the chip collection chamber 10. Larger debris on the support net 11 is cleaned manually after cutting.
