Description

Technical Field

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

[0002] Laser cutting equipment is a type of industrial equipment that uses a high-energy-density laser beam as a cutting tool to precisely process materials. It uses an optical system to focus the laser into a tiny spot, generating extremely high energy density, causing the irradiated material to instantly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material or aids combustion, thereby achieving cutting.

[0003] The patent with announcement number CN217551480U discloses a metal door and window processing laser cutting equipment, which relates to the field of metal door and window processing technology.

A rotating shaft is fixedly provided on the cutting device, and a locking mechanism for locking the rotating shaft is installed on the rotating shaft. Both sides above the rotating shaft are equipped with a motion device for driving the rotating shaft to rise and fall; when the angle of the cutting device needs to be adjusted, after the rotating shaft is rotated, the rotating shaft is fixed by the locking assembly, and the cutting device can be fixed. When the angle of the other side of the cutting device needs to be adjusted, the rotating shaft is deflected by the motion device, so that the other angle of the cutting device can be offset. The angle of the cutting device can be quickly adjusted through the above operation.

A track is provided on the top of the base 1, and the laser cutting assembly 3 is slidably connected to the track on the top of the base 1; A support mechanism 4 is provided at the bottom of the laser cutting assembly 3, which is used to cooperate with the clamping mechanism 2 to complete the processing and cutting of the workpiece and prevent the cut workpiece from falling out of the device; The top track of the base 1 is slidably connected to a conveying mechanism 5 for conveying the cut workpiece and cooperating with the supporting mechanism 4 to support the workpiece; A discharge mechanism 6 is fixedly connected to the front of the base 1 to cushion the workpieces at the discharge port and prevent them from falling and deforming.

[0018] The support mechanism 4 includes: a mounting seat 401, a hydraulic telescopic rod 402, a support plate 403, and a water-cooling pipe 404. The mounting seat 401 is fixedly connected to the bottom of the laser cutting component 3, and the hydraulic telescopic rod 402 is fixedly connected to the top of the mounting seat 401 through a base provided with an angle. The support plate 403 is rotatably connected to the front and rear surfaces of the laser cutting component 3. A circulating water path is opened inside the support plate 403. The water-cooling pipe 404 is fixedly connected to the left side of the support plate 403, and there are two water-cooling pipes 404, which are respectively connected to the water inlet and the water outlet. The other end of the water-cooling pipe 404 is fixedly connected to an external water-cooling circulation device.

[0019] The extended end of the hydraulic telescopic rod 402 is hinged at the bottom of the hydraulic telescopic rod 402 , and the end of the clamping block 203 away from the chuck 202 and the end of the connecting rod 206 away from the mounting ring 205 are hinged to each other.

[0020] Working principle: When the device is ready to run, the laser cutting component 3 and the conveying mechanism 5 are in the initial position of the device and do not affect the lifting of the metal material. The material is lifted into the appropriate position of the device. At this time, the clamping mechanism 2 and the laser cutting component 3 and the conveying mechanism 5 start to cooperate to fix the material. The principle of the clamping mechanism 2 during operation is as follows: the external motor starts to drive the transmission shaft 210 to move forward, driving the double-headed protrusion 208 to move so that it engages with the concave block 207. Then the external motor drives the transmission shaft 210 to start rotating. The rotation of the transmission shaft 210 drives the concave block 207 to rotate. The rotation of the concave block 207 drives the screw 204 to rotate. The rotation of the screw 204 drives the mounting ring 205 to move backward through the surface thread. The movement of the mounting ring 205 drives the connecting rod 206 to move. The connecting rod 206 moves and pulls the clamping block 203 along The connection point between the chuck 202 and the clamping block 203 is the center of the circle rotation. As the screw 204 rotates, the clamping block 203 will gradually clamp the metal material. When the metal material is clamped and fixed by the clamping block 203, the transmission shaft 210 is pulled back. Due to the self-locking property of the screw 204, the clamping block 203 will not reset after the transmission shaft 210 is pulled back and still has the clamping force. When the transmission shaft 210 is pulled back, the transmission shaft 210 drives the double-headed protrusion 208 to engage with the concave block 211. At this time, the external motor drives the entire clamping mechanism 2 to rotate, which can directly control the rotation of the workpiece to cooperate with the laser cutting component 3 to cut the metal material. In this way, workers do not need to perform tedious locking operations, which improves the loading speed and production efficiency, while also reducing the safety hazards caused by negligence in manual operation and improving the safety of the entire device. When the clamping mechanism 2 is working, the supporting mechanism 4 is also running at the same time. The hydraulic telescopic rod 402 extends to push the supporting plate 403 until it contacts the metal material and props it up. At this time, the material is installed and cutting begins. The laser cutting assembly 3 moves to the designed position and starts cutting. The designed workpiece style is cut out in conjunction with the rotation of the metal material. As the metal material rotates, the hydraulic telescopic rod 402 will extend and retract in real time to control the supporting plate 403 to always fit the material. During cutting, the material is supported to prevent deformation due to its own weight, resulting in a decrease in cutting quality. The flowing water in the water channel of the support plate 403 can also effectively transfer the heat generated by the workpiece during the cutting process, inhibit heat accumulation to offset deformation stress, and prevent its thermal deformation from affecting the cutting quality.

[0021] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, the conveying mechanism 5 includes: a fixed plate 501, an electric telescopic rod 502, a roller 503, a wheel frame 506, a mounting ring 508, and a reinforcing rib 509. The fixed plate 501 is slidably connected to the top track of the base 1, the mounting ring 508 is rotatably connected to the inner wall of the fixed plate 501, the electric telescopic rod 502 is fixedly connected to the inner wall of the mounting ring 508, the wheel frame 506 is fixedly connected to the end of the electric telescopic rod 502 away from the mounting ring 508, the roller 503 is rotatably connected to the inside of the wheel frame 506 through an internal motor, and the reinforcing rib 509 is fixedly connected to the inner wall of the mounting ring 508. 9 is fixedly connected to the rear of the fixed plate 501. The conveying mechanism 5 also includes: a grinding brush 504, an elastic member 505, and a connecting arm 507. The connecting arm 507 is hinged to the top of the wheel frame 506. The grinding brush 504 is fixedly connected to one end of the connecting arm 507. The elastic member 505 is fixedly connected to the other end of the connecting arm 507. The elastic member 505 is fixedly connected to the top of the wheel frame 506. Another supporting mechanism 4 is also provided at the rear of the fixed plate 501 and is connected by a reinforcing rib 509. The difference is that this supporting mechanism 4 does not have a water-cooling pipe 404 structure. This supporting mechanism 4 is used to cooperate with the conveying mechanism 5 to convey workpieces.

[0022] The discharging mechanism 6 includes: a slide beam 601, a conveying wheel 602, and a slide groove 604. The slide beam 601 is fixedly connected to the front part of the base 1, the conveying wheel 602 is rotatably connected between the two slide beams 601, and the slide groove 604 is opened on the inner wall of the slide beam 601. The discharging mechanism 6 also includes: a bearing seat 603, a guide column 605, an anti-slide block 606, a connecting seat 607, and a second connecting rod 608. The bearing seat 603 is fixedly connected to the top of the slide beam 601, the second connecting rod 608 is rotatably connected to the inner wall of the bearing seat 603, the connecting seat 607 is rotatably connected to the end of the second connecting rod 608 away from the bearing seat 603, the anti-slide block 606 is fixedly connected to the top of the connecting seat 607, the guide column 605 is fixedly connected to the left and right sides of the second connecting rod 608, the slide groove 604 is located on the movement trajectory of the guide column 605, and the anti-slide block 606 has friction on the workpiece sufficient to prevent the workpiece from displacement.

[0023] Working principle: During the operation of the device, the operation process of the conveying mechanism 5 is as follows: when the material is hoisted, the fixed plate 501 is driven by the internal motor to move along the top track of the base 1 toward the workpiece. When the workpiece is at the bottom of the roller 503, the electric telescopic rod 502 starts to push the wheel frame 506 to move. The movement of the wheel frame 506 drives the roller 503 to move until it contacts the metal material. The material is clamped through the cooperation between each electric telescopic rod 502 and the roller 503, which can also start the fixing of the metal material, further improving the clamping effect. When one section of the cutting is completed, the support mechanism 4 at the rear of the reinforcing rib 509 starts to contact and lift the workpiece. At this time, the fixed plate 501 is driven by the internal motor to move along the top track of the base 1 toward the discharge mechanism 6. After moving to the target position, the roller 503 is driven by the internal motor to start rotating. The friction between the roller 503 and the workpiece causes the workpiece to be discharged after the cutting is completed. The workpiece contacts the grinding brush 504 during the movement. As the workpiece moves, the grinding brush 504 removes the burrs and splashes on its surface caused by cutting, converting the transmission time into processing time, compressing the production cycle, and improving the overall efficiency of the device.

[0024] When the workpiece is cut and enters the discharge mechanism 6, the workpiece first contacts the conveying wheel 602. As the roller 503 discharges the workpiece, the workpiece gradually stretches. Under the influence of gravity, one end of the workpiece falls downward and contacts the anti-sliding block 606, pressing the anti-sliding block 606 downward. The anti-sliding block 606 moves downward, driving the connecting seat 607 to move downward. The connecting seat 607 moves downward and drives the connecting rod 2 608 to rotate. The connecting rod 2 608 rotates and drives the guide column 605 to move downward and compress the torsion spring inside the bearing seat 603. The guide column 605 moves downward into the slide groove 604 and is affected by the slide groove 606. 04 limit constraint causes the guide column 605 to rotate, and the rotation of the guide column 605 drives the connecting seat 607 to rotate, and the rotation of the connecting seat 607 drives the anti-sliding block 606 to rotate. After the anti-sliding block 606 rotates, it moves away from the workpiece, and the workpiece loses its constraint and slides out along the surface of the conveying wheel 602. The torsion spring inside the anti-sliding block 606 and the bearing seat 603 can effectively buffer the workpiece from entering the conveyor belt, preventing deformation of the workpiece due to collision, which leads to a decrease in the yield rate. After the workpiece passes the connecting seat 607, it is reset by the torsion spring and the connecting rod 2 608 is reset to prepare for the next operation.
