Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, in particular to automatic cutting equipment for processing aluminum profiles for doors and windows. Background Art

[0002] Doors and windows are essential materials for home decoration. With the development of science and technology, their functionality and aesthetics are gradually improving. To date, aluminum alloy doors and windows are still the most widely used materials for doors and windows. Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy profiles for frames, stiles, and sashes. When automatically cutting aluminum profiles for doors and windows, you must first determine the specifications and length of the aluminum profiles used, then determine the length to be cut, and use a clamp to fix the aluminum profile on the workbench from both sides, and finally cut the aluminum profile by sawing.

[0003] However, in the actual processing process, when the cutting saw is cutting the aluminum profile, there is not only the cutting force but also the mutual friction between the high-speed rotating saw blade and the aluminum profile, which makes the aluminum profile vibrate along with the cutting. At this time, if the clamping force is not enough, it will cause the aluminum profile to shake and dislocate, reducing the cutting accuracy. If the clamping force is too large, it will easily cause the thin wall of the aluminum profile to deform. At the same time, the rotation speed and feed rate of the cutting saw are also closely related to the cutting accuracy. In summary, it is difficult for existing cutting equipment to timely adjust the more appropriate clamping force, rotation speed and feed rate for aluminum profiles of different specifications, making it difficult to ensure cutting accuracy.

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.

[0024] Please refer to the attached Figure 1 -Attached Figure 7 The embodiment of the present invention provides an automatic cutting device for processing aluminum profiles for doors and windows, including a cutting table 10, a cutting unit 20 is arranged inside the cutting table 10, a cutting groove 101 corresponding to the cutting unit 20 is opened on the table top of the cutting table 10, a vertical clamping device 30 is arranged above the cutting groove 101, and horizontal clamping devices 40 are respectively arranged on both sides of the cutting groove 101. The vertical clamping device 30 cooperates with the table top of the cutting table 10 to clamp the aluminum profile in the vertical direction, and the horizontal clamping device 40 cooperates with a fixed baffle 102 fixed on the table top of the cutting table 10 to clamp the aluminum profile in the horizontal direction. The horizontal clamping device 40 and the vertical clamping device 30 The output ends are respectively provided with a detection unit 1 50 for detecting the vibration amplitude around the clamped part of the aluminum profile and the clamping feed amount of the horizontal clamping device 40 and the vertical clamping device 30, and the detection data is transmitted to the control unit for judgment, and then the control unit controls and adjusts the clamping feed amount of the horizontal clamping device 40 and the vertical clamping device 30.

[0025] By cooperating with the horizontal clamping device 40 and the vertical clamping device 30 respectively through the detection unit 50, the control unit can monitor the clamping feed amount of the horizontal clamping device 40 and the vertical clamping device 30 to the aluminum profile in real time according to the resistance change of the sliding rheostat 503, so as to avoid deformation of the thin wall of the aluminum profile caused by excessive clamping; at the same time, the vibration amplitude of the aluminum profile is judged according to the resistance change amplitude range of the sliding rheostat 503, and the horizontal clamping device 40 and the vertical clamping device 30 are controlled to clamp the aluminum profile more finely to avoid the situation of clamping virtual position, thereby avoiding the shaking and dislocation of the aluminum profile during the cutting process, and greatly improving the cutting accuracy. By setting up the detection unit 260, the control unit can realize the effect of automatic tool alignment of the cutting unit 20 and real-time monitoring of the cutting feed rate according to the resistance change of the sliding rheostat 2603. At the same time, according to the real-time feedback of the resistance change amplitude range of the sliding rheostat 2603, the vibration amplitude around the cut part of the aluminum profile is monitored, and the cutting speed and feed rate of the cutting unit 20 are adjusted according to the preset conditions to further improve the cutting accuracy.

[0026] A feed port 103 is provided on one side of the cutting table 10. The feed port 103 is a clamp consisting of a fixed baffle 102 and an adjusting baffle 104. The adjusting baffle 104 is fixedly connected to the output end of the adjusting cylinder 105. The outer wall of the adjusting cylinder 105 is fixedly connected to the side wall of the cutting table 10. The adjusting baffle 104 is driven to move by the adjusting cylinder 105, so that the distance between the adjusting baffle 104 and the fixed baffle 102 changes.

[0027] The feed port 103 is a limiting clamp consisting of a fixed baffle 102 and an adjusting baffle 104. According to the actual width of the aluminum profile, the adjusting baffle 104 is driven to move by the adjusting cylinder 105, so that the distance between the adjusting baffle 104 and the fixed baffle 102 is slightly larger than the actual width of the aluminum profile. In combination with a guiding curved surface with a certain curvature, the aluminum profile can be initially limited when being fed in by the feeder to ensure that the aluminum profile is within the clampable range.

[0028] A length calibration device is provided on the other side of the cutting table 10, which includes a slide bar group 106 composed of two slide bars, and both ends of the slide bar group 106 are fixedly connected to the side walls of the cutting table 10 through fixed blocks 107 respectively. A calibration baffle 108 passes through and is slidably connected to the outer wall of the slide bar group 106, and the outer wall of the uppermost slide bar of the slide bar group 106 is provided with a scale for indicating the length. A clamping device is also provided between the calibration baffle 108 and the cutting table 10, and the calibration baffle 108 is clamped and fixed to the cutting table 10 by the clamping device.

[0029] According to the required length of the aluminum profile, the position of the calibration baffle 108 is pre-set and fixed by clamping. When the aluminum profile is fed in, the end thereof collides with the calibration baffle 108, thereby achieving fixed-length cutting of the aluminum profile.

[0030] The vertical clamping device 30 includes two symmetrically arranged vertical cylinders 301. The outer wall of the vertical cylinder 301 is fixedly connected to the cutting table 10 through a bracket 302. A pressure block 303 is fixedly connected to the output end of the vertical cylinder 301. The two pressure blocks 303 are symmetrically distributed on both sides above the cutting groove 101.

[0031] The vertical cylinder 301 drives the pressing block 1 303 to descend, contact the top wall of the aluminum profile, and cooperate with the cutting table 10 to clamp and fix the aluminum profile in the vertical direction.

[0032] The horizontal clamping device 40 includes a plurality of horizontal cylinders 401 , which are arranged opposite to the fixed baffle 102 and fixedly connected to the side wall of the cutting table 10 via a second bracket 402 , and a second pressure block 403 is fixedly connected to the output end of the horizontal cylinder 401 .

[0033] The horizontal cylinder 401 drives the second pressing block 403 to move toward the fixed baffle 102, contact with the side wall of the aluminum profile, and cooperate with the fixed baffle 102 to clamp and fix the aluminum profile in the horizontal direction.

[0034] The detection unit 150 includes a plurality of ejector pins 1501, which penetrate through and are slidably connected to the middle of a follower block 1502. One end face of the ejector pin 1501 is set as a hemispherical surface, and the other end is fixedly connected to the slider end of a sliding rheostat 1503. The follower block 1502 is fixedly connected to the slider end of the sliding rheostat 1503 through a spring 1504. The spring 1504 is sleeved on the outer wall of the ejector pin 1501. The plurality of follower blocks 1502 are fixedly connected to the pressure block 1 303 and the pressure block 2 403 respectively. The outer walls of the plurality of sliding rheostats 1503 are fixedly connected to the outer walls of the vertical cylinder 301 and the horizontal cylinder 401 respectively. The signal output end of the sliding rheostat 1503 is electrically connected to the signal receiving end of the control unit.

[0035] When the horizontal clamping device 40 and the vertical clamping device 30 clamp and fix the aluminum profile, the hemispherical end of the ejector pin 1 501 first contacts the surface of the aluminum profile, and the resistance value of the sliding rheostat 1 503 changes. According to the resistance value at this time and the feeding distance of the vertical clamping device 30 or the horizontal clamping device 40, the current distance between the pressure block 1 303 or the pressure block 2 403 and the surface of the aluminum profile can be calculated by the control unit, and then the subsequent feeding length of the vertical cylinder 301 or the horizontal cylinder 401 can be accurately controlled by the control unit to achieve a more appropriate clamping force for the aluminum profile. Avoid the problem of too large or too small clamping force. At the same time, after the clamping is completed, during the cutting process, the vibration of the aluminum profile cooperates with the action of the spring 504 to drive the ejector pin 501 to move back and forth within a certain range, which is then fed back to the sliding rheostat 503, resulting in a certain range of resistance changes. The controller compares the resistance changes with the preset normal range. When it is greater than the normal range, it means that there are defects in the current clamping degree, cutting speed, and cutting feed amount. The clamping feed amount can be fine-tuned first. If it still does not meet the requirements, the cutting speed or cutting feed amount of the cutting unit 20 can be adjusted to solve the problem of excessive amplitude of the aluminum profile, thereby achieving the purpose of ensuring cutting accuracy. At the same time, it also achieves the purpose of timely adjusting the more appropriate clamping force, rotation speed and feed amount for aluminum profiles of different specifications.

[0036] The cutting unit 20 includes a cutting machine 201, the bottom end of which is fixedly connected to the moving end of a feeding device 202, and the bottom end of the feeding device 202 is fixedly connected to the inside of the cutting table 10. The feeding device 202 drives the cutting machine 201 to move, so that the saw blade of the cutting machine 201 moves along the cutting groove 101.

[0037] The feeding device 202 drives the cutting machine 201 to move, and the circular saw blade of the cutting machine 201 rotates and moves in the cutting groove 101, thereby realizing the rotary cutting of the aluminum profile.

[0038] The detection unit 2 60 includes a pin 2 601, which passes through and is slidably connected to the middle of the follower block 2 602. One end face of the pin 2 601 is set as a hemispherical surface, and the other end is fixedly connected to the slider end of the sliding rheostat 2 603. The side wall of the follower block 2 602 is fixedly connected to the slider end of the sliding rheostat 2 603 through a spring 2 604. The spring 2 604 is sleeved on the outer wall of the pin 2 601. The follower block 2 602 is fixedly connected to the outer wall of the cutting machine 201 through a follower frame 605. The bottom wall of the sliding rheostat 2 603 is fixedly connected to the top wall of the follower frame 605. The signal output end of the sliding rheostat 2 603 is electrically connected to the signal receiving end of the control unit.

[0039] When the feeding device 202 drives the cutting machine 201 to move toward the aluminum profile, the hemispherical end of the ejector pin 2 601 first contacts the surface of the aluminum profile. At this time, the resistance value of the sliding rheostat 2 603 changes. The control unit can calculate the current distance between the circular saw blade of the cutting machine 201 and the surface of the aluminum profile based on the resistance value at this time and the feeding distance of the feeding device 202. The control unit can then accurately control the feeding device 202 to drive the cutting machine 201 to feed this distance, so that the circular saw blade of the cutting machine 201 makes initial contact with the surface of the aluminum profile, thereby realizing the knife alignment process. When the actual cutting is performed, the vibration of the aluminum profile cooperates with the action of the spring 2 604 to drive the ejector 2 601 to move back and forth within a certain range, which is then fed back to the sliding rheostat 2 603, resulting in a certain range of resistance changes. The controller compares the resistance changes with the preset normal range. When it is greater than the normal range, it indicates that there are defects in the current cutting speed and cutting feed amount. The feed amount of the feed device 202 or the cutting speed of the cutting machine 201 can be adjusted to solve the problem of excessive amplitude of the aluminum profile, thereby achieving the purpose of ensuring cutting accuracy. At the same time, it also achieves the purpose of timely adjusting the more appropriate cutting rotation speed and feed amount for aluminum profiles of different specifications.
