Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window processing technology, and in particular to a continuous fixed-length cutting device for aluminum materials used in the production of aluminum alloy door and window frames. Background Art

[0002] Aluminum is extruded into key profiles for aluminum alloy doors and windows, with a rectangular cross-section for easy installation. After slotting, door and window frames can be assembled, and glass windows or doors can be installed. Due to its light weight, high strength, excellent corrosion resistance, and aesthetic appeal and durability, it is widely used in the field of building decoration. Different building scenarios require door and window frames of various sizes, so cutting aluminum to a certain length is an essential process.

[0003] For example, the continuous fixed-length aluminum cutting device for aluminum alloy door and window frame production, authorized by announcement number "CN221134240U", requires the longitudinal driving structure to control the longitudinal traveling table to approach the cutting structure to complete the cutting each time. This ensures that the length of the aluminum material remains constant each time. However, this cutting device clamps the aluminum material through a fixed-length plate, an adjusting plate, and an end clamping plate. But the hole spacing of the adjusting plate is fixed, which makes it inaccurate for non-standard or special-specification aluminum materials. If there is a very small or very large dimensional deviation, it is difficult to fix it accurately, affecting the cutting accuracy and quality. Moreover, each fixation requires manual rotation of the bolts, which increases the workload of the operator. At the same time, aluminum alloy door and window frames have diverse designs, and the fixed angle of the cutting blade of this cutting device greatly restricts product design and cannot meet the diverse cutting methods. Summary of the Invention

[0004] This utility model aims to solve the problems existing in the prior art by providing a continuous fixed-length cutting device for aluminum materials used in the production of aluminum alloy door and window frames. This device can clamp and fix aluminum materials of various specifications without the need for manual rotation of bolts or adjustment of the cutting blade angle.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This continuous fixed-length cutting device for aluminum alloy door and window frame production includes a base and a first bending block. The rear end of the base is fixedly connected to the first bending block. The inner wall of the first bending block is fixedly connected to a second electric telescopic rod. The output end of the second electric telescopic rod is fixedly connected to a block. The inner wall of the block is slidably connected to a first housing. The inside of the first housing is provided with a cutting blade angle adjustment structure. The left end of the base is fixedly connected to a third servo motor. The output shaft of the third servo motor is fixedly connected to a threaded rod. Both the left and right ends of the threaded rod are rotatably connected to the base through bearings.

[0006] To further improve the design, the cutting blade angle adjustment structure includes a multi-stage electric push rod. The outer wall of the multi-stage electric push rod is fixedly connected to the first housing. The output end of the multi-stage electric push rod is fixedly connected to a rack. The upper end of the rack is slidably connected to a first slide rod. Both ends of the first slide rod are fixedly connected to the first housing. The rack meshes with a first gear. The rotation shaft of the first gear is fixedly connected to a round rod. Both ends of the rotation shaft of the round rod are rotatably connected to the first housing through bearings. The lower end of the round rod is fixedly connected to a first servo motor. The output shaft of the first servo motor is fixedly connected to the cutting blade.

[0007] Further improvements include: the end of the first housing is fixedly connected to the third electric telescopic rod; the third electric telescopic rod is slidably connected to the first bent block via a protrusion machined at its end; the threaded rod is threadedly connected to the threaded block; and the lower end of the threaded block is slidably connected to the third sliding rod.

[0008] Further improvements include fixing both ends of the third slide rod to the base, sliding the threaded block to the base via a protrusion machined at the upper end, and fixing a square plate to the upper end of the threaded block.

[0009] Further improvements include the addition of a second housing fixedly connected to the upper ends of both the square plate and the base, with an aluminum positioning and clamping structure inside the second housing, and a processing table fixedly connected to the upper right side of the base.

[0010] Further improvements include the following aluminum positioning and clamping structure: a second servo motor, the outer wall of which is fixedly connected to a second housing; a second gear is fixedly connected to the output shaft of the second servo motor; the second gear meshes with a third gear; both ends of the rotating shafts of the second and third gears are rotatably connected to the second housing via bearings; connecting rods are fixedly connected to the outer walls of the rotating shafts at the ends of the second and third gears; a cylinder is fixedly connected to the end of the connecting rod; the outer wall of the cylinder is slidably connected to a groove frame; the inner walls of the upper and lower sides of the groove frame are slidably connected to a second sliding rod; both ends of the second sliding rod are fixedly connected to the second housing; the outer wall of the groove frame is slidably connected to the second housing; a second bent block is fixedly connected to the upper end of the second housing; and a first electric telescopic rod is fixedly connected to the inner wall of the second bent block.

[0011] The beneficial effects of this utility model are as follows: In this utility model, through the cooperation of the aluminum material positioning and clamping structure and the second housing, the output shaft of the second motor rotates, driving the second gear to rotate, and the second gear rotates, driving the third gear to rotate. At this time, the second gear and the third gear rotate in opposite directions. The rotation of the second gear and the third gear drives the two connecting rods to rotate relative to each other. The rotation of the connecting rods causes the cylinder to slide up and down in the groove frame. Because the groove frame causes the cylinder to slide up and down, the cylinder causes the groove frame to slide relative to the second slide rod until the inner wall of the second slide rod is pressed against the aluminum material, thus completing the positioning of the aluminum material. At this time, the aluminum material is centered, which facilitates subsequent cutting operations. The output end of the first electric telescopic rod moves downward. The output end of the first electric telescopic rod is equipped with a pressure plate until the pressure plate is pressed against the aluminum material, thus completing the fixing of the aluminum material.

[0012] By cooperating with the cutting blade angle adjustment structure and the first housing, the output end of the multi-stage electric push rod moves, causing the rack to slide on the first slide rod. The rack moves, causing the gear to rotate. The gear rotates, causing the round rod to rotate. The round rod rotates, causing the first servo motor to rotate. The first servo motor rotates, causing the cutting blade to rotate, thereby achieving the purpose of adjusting the cutting blade angle. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] See attached document Figure 1-7 In this embodiment, a continuous fixed-length cutting device for aluminum alloy door and window frame production includes a base 1 and a first bending block 2. The rear end of the base 1 is fixedly connected to the first bending block 2. The inner wall of the first bending block 2 is fixedly connected to a second electric telescopic rod 12.

[0023] The first housing 3 has a cutting blade angle adjustment structure 4 inside. The left end of the base 1 is fixedly connected to a third servo motor 8. The output shaft of the third servo motor 8 is fixedly connected to a threaded rod 9. The rotation of the output shaft of the third servo motor 8 drives the threaded rod 9 to rotate. Both ends of the threaded rod 9 are rotatably connected to the base 1 through bearings. The threaded rod 9 rotates in the base 1 through the bearings.

[0025] See attached document Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The cutting blade angle adjustment structure 4 includes a multi-stage electric push rod 401. The model of the multi-stage electric push rod 401 is selected according to actual needs, and only those that meet the working requirements are selected. The outer wall of the multi-stage electric push rod 401 is fixedly connected to the first housing 3. The output end of the multi-stage electric push rod 401 is fixedly connected to the rack 402. The movement of the output end of the multi-stage electric push rod 401 drives the rack 402 to move. The upper end of the rack 402 is slidably connected to the first slide rod 404. The rack 402 slides on the first slide rod 404. Both ends of the first slide rod 404 are fixedly connected to the first housing 3. The rack 402 is meshed with the first gear 403. The movement of the rack 402 drives the first gear 403 to rotate.

[0026] The rotating shaft of the first gear 403 is fixedly connected to the round rod 405. The rotation of the first gear 403 drives the round rod 405 to rotate. Both ends of the rotating shaft of the round rod 405 are rotatably connected to the first housing 3 through bearings. The round rod 405 rotates inside the first housing 3 through the bearings. The lower end of the round rod 405 is fixedly connected to the first servo motor 406. The rotation of the round rod 405 drives the first servo motor 406 to rotate. The first servo motor 406 is connected to the battery through wires. The battery is connected to a switch, which is connected to an external control device. The output shaft of the first servo motor 406 is fixedly connected to the cutting blade 407. The rotation of the output shaft of the first servo motor 406 drives the cutting blade 407 to rotate.

[0027] See attached document Figure 1 , Figure 2 , Figure 4 and Figure 5The aluminum positioning and clamping structure 6 includes a second servo motor 601. The outer wall of the second servo motor 601 is fixedly connected to the second housing 5. The output shaft of the second servo motor 601 is fixedly connected to a second gear 602. The rotation of the output shaft of the second servo motor 601 drives the second gear 602 to rotate. The second gear 602 is meshed with a third gear 603. The rotation of the second gear 602 drives the third gear 603 to rotate. The rotation directions of the second gear 602 and the third gear 603 are opposite.

[0028] The two ends of the rotating shafts of the second gear 602 and the third gear 603 are rotatably connected to the second housing 5 through bearings. The second gear 602 and the third gear 603 rotate within the second housing 5 through bearings. The outer walls of the rotating shafts at the ends of the second gear 602 and the third gear 603 are fixedly connected to connecting rods 604. The rotation of the second gear 602 and the third gear 603 drives the two connecting rods 604 to rotate in opposite directions. The ends of the connecting rods 604 are fixedly connected to cylinders 605. The rotation of the connecting rods 604 drives the cylinders 605 to rotate. The outer wall of the cylinders 605 is slidably connected to the groove frame 606. The cylinders 605 slide within the groove frame 606.

[0029] The inner walls of the upper and lower sides of the groove frame 606 are slidably connected to the second slide rod 607. The groove frame 606 slides on the second slide rod 607.

The groove frame 606 slides inside the second housing 5. The upper end of the second housing 5 is fixedly connected to the second bent block 608. The inner wall of the second bent block 608 is fixedly connected to the first electric telescopic rod 609. The output end of the first electric telescopic rod 609 is equipped with a pressure plate. The pressure plate is made of medium carbon steel 45 steel, which has good hardness and toughness, can prevent deformation and wear, and has toughness to ensure that it will not break under sudden overload, thus ensuring stable clamping of aluminum material.

[0030] Work away from:

[0031] Continuous fixed-length cutting operation of aluminum materials used in the production of aluminum alloy door and window frames:

[0032] Placement of aluminum materials:

[0033] Place the aluminum material between the two sets of recessed frames 606, connect the external power supply to the left-side second motor 601, and start the left-side second motor 601. The output shaft of the second motor 601 rotates, driving the second gear 602 to rotate (as shown in the image). Figure 4The rotation of the second gear 602 drives the rotation of the third gear 603. At this time, the second gear 602 and the third gear 603 rotate in opposite directions. The rotation of the second gear 602 and the third gear 603 drives the two connecting rods 604 to rotate relative to each other. The rotation of the connecting rods 604 drives the cylinder 605 to slide up and down within the groove frame 606. Because the groove frame 606 causes the cylinder 605 to slide up and down, the cylinder 605 causes the groove frame 606 to slide relative to the second slide rod 607 until the inner wall of the groove frame 606 is in contact with the aluminum material. After positioning the aluminum material, which is now centered for easier subsequent cutting, turn off the second motor 601 and start the first electric telescopic rod 609. The output end of the first electric telescopic rod 609 moves downward. A pressure plate is installed at the output end of the first electric telescopic rod 609. The pressure plate is made of medium carbon steel 45 steel, which has good hardness and toughness, preventing deformation and wear. Its toughness ensures that it will not break under sudden overload, ensuring a stable clamping of the aluminum material. When the pressure plate and the aluminum material are tightly pressed together, turn off the first electric telescopic rod 609 to complete the fixing of the aluminum material.

[0034] Adjusting the cutting blade angle:

[0035] The multi-stage electric actuator 401 is activated, and the output end of the multi-stage electric actuator 401 moves, causing the rack 402 to slide on the first slide bar 404 (e.g. Figure 6 The rack 402 moves, causing the gear 403 to rotate. The gear 403 rotates, causing the round rod 405 to rotate. The round rod 405 rotates, causing the first servo motor 406 to rotate. The first servo motor 406 rotates, causing the cutting blade 407 to rotate, thereby achieving the purpose of adjusting the angle of the cutting blade 407.

[0036] Continuous fixed-length cutting of aluminum:

[0037] When the external power supply of the third servo motor 8 is connected and the third motor 8 is started, the output shaft of the third motor 8 rotates, driving the threaded rod 9 to rotate (e.g. Figure 2 The rotation of threaded rod 9 causes threaded block 10 to slide on third slide rod 11. The movement of threaded block 10 causes square plate 7 to move, and the movement of square plate 7 causes aluminum material to move to the right. The length of aluminum material to the right of cutting blade 407 is the length to be cut. Move the aluminum material to the length to be cut, connect the external power supply of the second motor 601 on the right, start the second motor 601 and the first electric telescopic rod 609 on the right. The second motor 601 and the first electric telescopic rod 609 on the right fix the aluminum material through the above operation. Turn off the second motor 601 and the first electric telescopic rod 609 on the right, start the first servo motor 406. The first servo motor 406 is connected to the battery through wires. The battery is connected to a switch, and the switch is connected to an external control device. The output shaft of the first servo motor 406 rotates, causing cutting blade 407 to rotate. Start the second electric telescopic rod 12. The output end of the second electric telescopic rod 12 moves, causing block 13 to move (e.g., Figure 2 The movement of block 13 moves the first housing 3, which in turn moves the cutting blade 407 downwards. This activates the third electric telescopic rod 14, whose output moves the first housing 401 back and forth. The first housing 401 then moves the cutting blade 407 back and forth. Through the coordination of the second electric telescopic rod 12, the third electric telescopic rod 14, and the first servo motor 406, the aluminum material is cut. After each cut, the second electric telescopic rod 12 moves the cutting blade 407 upwards away from the aluminum material. Then, the second motor 601 on the left and the first electric telescopic rod 609 on the left are activated again, causing the output of the first electric telescopic rod 609 to move upwards away from the aluminum material. The material is cut, and the second servo motor 601 on the left is started. The output shaft of the second servo motor 601 on the left reverses, causing the two sets of groove frames 606 to move away from the aluminum material. The third motor 8 moves the aluminum material positioning and clamping structure 6 on the left back to its original position. At this time, the aluminum material positioning and clamping structure 6 on the right is no longer fixed to the aluminum material, so the cut aluminum material can be taken out. Repeat the above operation to realize the continuous fixed-length cutting operation of aluminum material. It should be further explained that the fixed length is because the distance moved by the subsequent threaded block 10 is the same as the distance moved by the threaded block 10 for the first time. After the aluminum material is cut, the cut aluminum material is collected and all power is turned off for the continuous fixed-length cutting device for aluminum alloy door and window frame production.
