Description

Technical Field

[0001] The invention relates to the technical field of door and window positioning and cutting, in particular to a positioning and cutting device for alloy door and window processing. Background Art

[0002] Alloy doors and windows refer to doors and windows made of aluminum alloy or other alloy materials, which have the advantages of high strength, light weight, corrosion resistance, and easy processing. Alloy doors and windows are usually designed in a modern and beautiful style, with excellent heat insulation, sound insulation, waterproof and windproof performance, and are widely used in residential, commercial buildings and industrial places. Due to the strong plasticity of alloy materials, alloy doors and windows can be made into various types and shapes to meet different architectural styles and functional requirements.

[0003] For example, Chinese patent publication number CN119187680A discloses an automatic clamping and fixing metal door and window cutting machine, which belongs to the technical field of metal door and window processing and cutting machines, including a rotating seat rotatably mounted on the upper surface of the frame and a conveying frame mounted on the upper surface of the frame, a support frame is fixedly mounted on the outer side of the rotating seat, and a cylinder is fixedly mounted on the upper end of the support frame, and the output end of the cylinder is fixedly connected to a mounting plate, and a cutting assembly is fixedly mounted on the outer side of the mounting plate; it also includes: two first rotating shafts, elastically rotatably mounted on both sides of the conveying frame on the left side, and the outer sides of the first rotating shafts are respectively fixedly mounted with conveying assemblies and clamps; a support table, which is mounted above the rotating seat, and a cutting slit is opened on the support table. The automatic clamping and fixing metal door and window cutting machine can automatically convey and position metal profiles, ensure cutting accuracy, and can automatically sweep and clean the waste generated during the cutting process.

[0004] However, in the actual cutting process, if the tool descends too fast and the cutting speed is slow, the door and window profiles may bend and deform due to uneven force; on the contrary, if the cutting speed is too fast and the descending speed is slow, the cutting efficiency will be reduced because the tool cannot fully contact and cut the material, thus affecting the overall processing speed and quality. Therefore, under the premise of ensuring the quality of the profile after cutting, it is particularly important to control the cutting speed and the synchronous coordination of the cutting knife's descending speed.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 8 The present invention provides a technical solution: a positioning and cutting device for alloy door and window processing, comprising a workbench 1, two mirror-image side panels 2 are fixedly installed on the top of the workbench 1, the outer walls of the two side panels 2 are both installed with mounting plates 3, and the outer walls of the mounting plates 3 are installed with two clamping plates 4 that can be adjusted to move closer or farther away from each other;

[0033] It also includes an elastic clamping assembly installed on the opposite surfaces of the two clamping plates 4. When the two clamping plates 4 are close to each other, the elastic clamping assembly can clamp the door and window profile 7. The elastic clamping assembly located on the two mounting plates 3 is respectively provided with a laser transmitter 8 and a laser receiver 9. After the elastic clamping assembly clamps the door and window profile 7, the laser transmitter 8 and the laser receiver 9 are parallel to the clamping surface.

[0034] It also includes a cutting component that can cut the door and window profile 7.

[0035] See also Figure 1 as well as Figure 2When the device is used, the staff first fixes the door and window profile 7 to be cut between two groups of clamping plates 4 through an external device, and uses an external driving component to make the clamping plates 4 between each group close to each other, so that the two groups of elastic clamping components clamp the door and window profile 7. If the door and window profile 7 is a qualified product, the laser receiver 9 can receive the rays emitted by the laser transmitter 8. At this time, the cutting component is started to cut the door and window profile 7. Whether the door and window profile 7 will be damaged during the cutting process is determined by whether the laser receiver 9 can receive the rays emitted by the laser transmitter 8:

[0036] If the cutting speed is too slow and the descending speed is too fast, the door and window profile 7 may be bent and deformed due to uneven force, and the tool may be damaged. The deformation may cause the cutting line to deviate from the predetermined position, affecting the size and shape of the product;

[0037] If the cutting speed is too fast and the descending speed is too slow, the cutter will idle and fail to fully contact the door and window profile 7, resulting in a decrease in cutting rate. Slow cutting will cause local overheating of the plastic material, resulting in melting and burrs, affecting the quality of the cut surface.

[0038] Therefore, the laser transmitter 8 and the laser receiver 9 are used to detect whether the door and window profile 7 will bend during the cutting process. If bending occurs, it may be caused by the descent speed being too fast and the cutting speed being too slow. If no bending occurs, the descent speed of the tool can be appropriately increased to improve the cutting efficiency, while also reducing the generation of burrs.

[0039] Among them, the cooperation between the laser transmitter 8 and the laser receiver 9 can also detect whether the door and window profile 7 is bent or deformed in the initial state. If the door and window profile 7 is a qualified product and has not been bent in the initial state, the laser receiver 9 can receive the rays emitted by the laser transmitter 8. If the door and window profile 7 is in a bent state in the initial state, the laser receiver 9 cannot receive the rays emitted by the laser transmitter 8.

[0040] Furthermore, the elastic clamping assembly includes two clamping links 13 rotatably mounted on the outer wall of the clamping plate 4, a clamping roller 5 is mounted at one end of the two clamping links 13, and a first elastic telescopic rod 14 is rotatably connected between the two clamping rollers 5, a first spring 15 is fixedly mounted between the clamping plate 4 and one of the clamping links 13, the laser transmitter 8 and the laser receiver 9 are respectively mounted on the outer walls of the corresponding clamping rollers 5 and fixedly connected to the first elastic telescopic rod 14, and the directions of emission and reception coincide with the extension line of the axis of the first elastic telescopic rod 14.

[0041] See also Figure 5, taking one set of elastic clamping components as an example, each set of elastic clamping components is connected to the clamping roller 5 through two clamping connecting rods 13 to clamp the door and window profile 7. When the two clamping plates 4 are driven to approach each other by the external driving structure, see Figure 6 , the two clamping rollers 5 close to the angle between the two clamping plates 4 will first contact the door and window profile 7, and in the process of the two clamping plates 4 constantly approaching, they will rotate along the outer wall of the door and window profile 7 toward the direction close to the angle between the two clamping plates 4. When the other two clamping rollers 5 contact the door and window profile 7, as the two clamping plates 4 continue to approach, the two clamping connecting rods 13 on the same clamping plate 4 will gradually move away until the first elastic telescopic rod 14 is parallel to the door and window profile 7. At this time, the stretching of the first elastic telescopic rod 14 is maximum, so that the four clamping rollers 5 on one side complete the clamping of the door and window profile 7, and the same applies to the other side.

[0042] The laser transmitter 8 and the laser receiver 9 are respectively installed on the corresponding clamping roller 5. Figure 3 As shown in the figure, the upper clamping roller 5 is equipped with a laser emitter 8, and the outer wall of the other clamping roller 5 corresponding to the level of the upper clamping roller 5 in the figure is equipped with a laser receiver 9, and the laser emitter 8 and the laser receiver 9 are coincident with the extension line of the axis of the corresponding first elastic telescopic rod 14. When the clamping roller 5 clamps the door and window profile 7 through the external driving structure, the first elastic telescopic rod 14 is parallel to the door and window profile 7, that is, the rays emitted by the laser emitter 8 are parallel to the door and window profile 7. If the door and window profile 7 is not deformed during the cutting process, the laser receiver 9 can continuously receive the rays emitted by the laser emitter 8. If the laser receiver 9 cannot continuously receive the rays emitted by the laser emitter 8 during the cutting process, the door and window profile 7 may be deformed, and it is necessary to increase the cutting speed or reduce the speed at which the tool descends.

[0043] It is worth mentioning that when the door and window profile 7 is bent in the initial state, the laser receiver 9 cannot receive the rays emitted by the laser transmitter 8 after clamping. After clamping, it can be determined whether the door and window profile 7 has been bent before cutting.

[0044] In addition, the two corresponding clamping rollers 5 on each clamping plate 4 roll in opposite directions, and can be locked autonomously after the door and window profile 7 is clamped to prevent deviation during the subsequent cutting process. Friction can also be reduced during the clamping process to prevent damage to the door and window profile 7 and the clamping rollers 5.

[0045] Further, two rotating gears 10 are rotatably installed on the outer wall of the mounting plate 3, the clamping plate 4 is fixedly installed on the outer wall of the corresponding rotating gear 10, a sliding plate 28 is slidably installed on the outer wall of the mounting plate 3, and the outer walls on both sides of the sliding plate 28 are fixedly connected with the first rack 11 meshing with the rotating gear 10, the outer wall of the mounting plate 3 is fixedly connected with the vertical plate 12, the outer wall of the vertical plate 12 is fixedly connected with the limiting frame 31, one end of the sliding plate 28 passes through the outer wall of the vertical plate 12 and is slidably connected to the inner wall of the limiting frame 31, and the outer wall of the penetrating part of the sliding plate 28 is fixedly connected with the second rack 17, the outer wall of the vertical plate 12 is rotatably installed with an incomplete gear 18 that can mesh with the second rack 17, and a second spring 16 is installed between the inner wall of the limiting frame 31 and the outer wall of the sliding plate 28;

[0046] It also includes a locking component, which can lock the sliding plate 28 when the sliding plate 28 slides to the farthest distance and the laser receiver 9 is able to receive the laser emitted by the laser transmitter 8.

[0047] See also Figure 5 as well as Figure 6 When the door and window profile 7 to be cut needs to be clamped, the incomplete gear 18 is driven to rotate by a motor fixed on the outer wall of the vertical plate 12. Through the cooperation of the incomplete gear 18 and the second rack 17, the sliding plate 28 is driven to move away from the vertical plate 12. At the same time, the first rack 11 on the sliding plate 28 drives the rotating gear 10 to rotate, so that the two clamping plates 4 are close to each other, and then the four clamping rollers 5 clamp the door and window profile 7.

[0048] When the teeth of the incomplete gear 18 are disengaged from the second rack 17, if the door and window profile 7 is a qualified product in the initial state, the first elastic telescopic rod 14 is in a horizontal state and parallel to the door and window profile 7, and the rays emitted by the laser transmitter 8 can be received by the laser receiver 9, then the sliding plate 28 is locked through the locking assembly, thereby clamping the door and window profile 7 for subsequent cutting;

[0049] If the door and window profile 7 is in a bent state in the initial state, when the sliding plate 28 moves to the farthest distance, the first elastic telescopic rod 14 will not be in a horizontal state, and the laser transmitter 8 and the laser receiver 9 on both sides will not be in the same horizontal state, that is, the laser receiver 9 cannot receive the rays emitted by the laser transmitter 8. At this time, the locking component will not lock the sliding plate 28, so that the sliding plate 28 can not be locked. Figure 5 For example, under the action of the second spring 16, the sliding plate 28 will move toward the direction close to the door and window profile 7, and then drive the two clamping plates 4 to move away from the door and window profile 7, and the door and window profile 7 cannot be clamped, so as to remind the staff that the door and window profile 7 itself is unqualified and may be partially bent.

[0050] Furthermore, the locking assembly includes a mounting base 19 fixed on the top of the sliding plate 28, a locking rod 20 is fixedly connected to the outer wall of the mounting base 19, and a locking head 22 with a hemispherical design is fixedly connected to the end of the locking rod 20 away from the mounting base 19, and a magnet is installed inside the locking head 22, the outer wall of the vertical plate 12 is fixedly connected to the locking frame 23, the inner walls on both sides of the locking frame 23 are fixedly installed with a second elastic telescopic rod 24, and the end of the telescopic end of the second elastic telescopic rod 24 is set to an acute-angled inclined surface, and an unlocking head 21 is slidably installed on the outer wall of the locking rod 20, and an electromagnet is installed inside the unlocking head 21.

[0051] Furthermore, the laser receiver 9 is electrically connected to the electromagnet inside the unlocking head 21 .

[0052] See also Figure 7 As can be seen from the above, when the sliding plate 28 moves in the direction away from the door and window profile 7, the two clamping plates 4 approach each other and clamp the door and window profile 7 through the clamping roller 5. In the initial state, the electromagnet in the unlocking head 21 is started by external control to attract the magnet in the locking head 22, and the unlocking head 21 will contact and abut against the locking head 22. At this time, the two can be regarded as a whole. When the sliding plate 28 slides to the farthest distance, the telescopic end of the second elastic telescopic rod 24 is just in the gap between the locking head 22 and the unlocking head 21. If the door and window profile 7 is a qualified product, the laser receiver 9 can receive the rays emitted by the laser transmitter 8 at this time, and it will control the electromagnet inside the unlocking head 21 to stop working, and the acute angle bevel of the telescopic end of the second elastic telescopic rod 24 will be embedded between the unlocking head 21 and the locking head 22, so that the plane of the locking head 22 is abutted against the plane of the telescopic end of the second elastic telescopic rod 24, completing the locking hanging process, and preventing unnecessary sliding during subsequent cutting;

[0053] If the laser receiver 9 does not receive the rays emitted by the laser transmitter 8 when the sliding plate 28 slides to the farthest distance, it means that the door and window profile 7 has been bent at this time, and the electromagnet in the unlocking head 21 continues to work, so that the telescopic end of the second elastic telescopic rod 24 cannot be embedded between the unlocking head 21 and the locking head 22.

[0054] When the sliding plate 28 needs to be unlocked, the electromagnet in the unlocking head 21 is driven to work again. At this time, the electromagnet in the unlocking head 21 will attract the magnet in the locking head 22, and the telescopic end of the second elastic telescopic rod 24 will be retracted through the unlocking head 21. Under the action of the second spring 16, the sliding plate 28 will move toward the direction close to the door and window profile 7, thereby completing the unlocking.

[0055] Furthermore, a connecting rod is fixedly connected to the outer wall of the unlocking head 21 , and the connecting rod passes through the mounting seat 19 and is fixedly mounted with an unlocking button 25 .

[0056] When the door and window profile 7 is a qualified product, after it is clamped, the electromagnet in the unlocking head 21 stops working through electrical connection. At this time, the telescopic end of the second elastic telescopic rod 24 will be embedded between the unlocking head 21 and the locking head 22, which may cause the unlocking head 21 to bounce towards the direction close to the mounting seat 19, that is, Figure 7 As shown in the figure, the unlocking process cannot be completed simply by the cooperation of the electromagnet and the magnet. At this time, the staff presses the unlocking button 25 to drive the unlocking head 21 to move toward the locking head 22, thereby completing the manual unlocking process.

[0057] Furthermore, the cutting assembly comprises a cutting frame 6 fixedly mounted on the top of the workbench 1 , the inner wall of the cutting frame 6 is mounted with a mounting frame 29 capable of vertical sliding adjustment, and the inner wall of the mounting frame 29 is mounted with a rotatable cutting knife 30 .

[0058] See also Figure 2 The mounting frame 29 is vertically adjusted by a cylinder fixed on the top of the cutting frame 6, and the cutting knife 30 is rotated by a motor fixed on the outer wall of the mounting frame 29. When the door and window profile 7 is to be cut, the cylinder and the motor are started to make the cutting knife 30 rotate and move downward to complete the cutting of the door and window profile 7.

[0059] If the signal received by the laser receiver 9 disappears during this process, it means that the door and window profile 7 is bent, that is, the motor power is too small or the cylinder power is too large. The staff will adjust the two to find the best matching power to ensure cutting efficiency while ensuring cutting quality.

[0060] Furthermore, the mounting plate 3 and the side plate 2 are rotatably connected.

[0061] See also Figure 4 The mounting plate 3 and the side plate 2 are rotatably connected. In the initial stage, the two clamping plates 4 on one side are first brought close to each other to clamp one end of the door and window profile 7, and then the two clamping plates 4 on the other side are controlled to approach to complete the clamping of the door and window profile 7. Gradual clamping can evenly distribute the clamping force, avoid stress concentration caused by one-time clamping, and reduce the risk of deformation of the door and window profile 7. In addition, when the clamping roller 5 on the other side away from the vertical plate 12 initially contacts the door and window profile 7, the first elastic extension The retractable rod 14 is parallel to the door and window profile 7, but at this time the two side clamps 4 are still moving and have not reached the clamping state. At this time, if the door and window profile 7 is a qualified product, all the first elastic telescopic rods 14 are in a parallel state, and the laser receiver 9 can receive the rays emitted by the laser transmitter 8. If the rays received by the laser receiver 9 are intermittent, the surface of the door and window profile 7 may be bumped instead of bent. At this time, the staff can check whether the door and window profile 7 meets the processing requirements to prevent affecting the quality of subsequent finished products.

[0062] Furthermore, the rotating shaft of the mounting plate 3 passes through the outer wall of the side plate 2 and is fixedly mounted with a connecting disc 26, the outer wall of the connecting disc 26 is threadedly connected with a locking pin 27, and the outer wall of the side plate 2 is provided with a socket for inserting the locking pin 27.

[0063] See also Figure 8 When the door and window profile 7 is clamped and the sliding plate 28 is locked by the locking head 22 and the second elastic telescopic rod 24, the staff inserts the locking pin 27 into the socket of the side panel 2 to complete the locking of the side panel 2 to prevent unnecessary rotation of the side panel 2 during the subsequent cutting process to affect the cutting.

[0064] Furthermore, a tension spring is provided inside the first elastic telescopic rod 14 .

[0065] See also Figure 5 as well as Figure 6 The first elastic telescopic rod 14 is provided with a tension spring inside. After the door and window profile 7 is clamped by the clamping roller 5, during the cutting process, the tension spring inside the first elastic telescopic rod 14 and the first spring 15 will act together on the first elastic telescopic rod 14, which can reduce the vibration during the cutting process to a certain extent, make the cutting line straighter and smoother, and ensure the accuracy and consistency of the cutting size.

[0066] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
