Description

Technical Field

[0001] This utility model relates to the field of angle steel cutting technology, specifically a laser cutting device for processing angle steel tower plates. Background Technology

[0002] In the field of steel structure processing, angle steel, as a common profile, is widely used in industries such as construction, bridges, and machinery manufacturing. The cutting of angle steel is one of the key processes in the processing, and its accuracy and efficiency directly affect the quality and cost of subsequent welding and assembly. For example, in a steel profile laser cutting production line disclosed in Chinese patent literature (application number: 202322706888.8), the steel is clamped and fixed before being cut. The slider drives the receiving plate, and the receiving plate drives the anti-slip plate. The two sets of anti-slip plates come together to complete the clamping of the steel. This method can only perform fixed cutting of steel of fixed size or model. With the movement of the anti-slip plates, right-angle steel can be fixedly cut. For example, in irregular structures or special design requirements, if it is necessary to cut angle steel with non-standard angles (such as 45°, 60° or 120°), traditional equipment requires manual adjustment of the clamps or replacement of molds, which leads to cumbersome operation, time-consuming and labor-intensive operation, and is prone to human error.

[0003] Therefore, we propose a laser cutting device for processing angle steel tower steel plates. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6 This utility model provides a technical solution: a laser cutting device for processing angle steel tower steel plates, including a cutting table 1, a first reduction motor 3, a first support 8, a second support 9, a laser cutter 18, and a second reduction motor 19. The first support 8 and the second support 9 are both fixedly installed on the top of the cutting table 1. A fixing plate 2 is fixedly installed on the top of the cutting table 1. Two sets of fixing plates 2 are provided. A threaded rod 4 is disposed between the two sets of fixing plates 2. A push plate 5 is installed on the threaded rod 4. The lower part of the push plate 5 is provided with a threaded hole that mates with the threaded rod 4. A guide rod 6 is installed on the lower part of the push plate 5. The push plate 5 and the guide rod 6 are movably connected. A first mounting groove 7 is provided... On the cutting table 1, a second mounting groove 101 is located at the top center of the cutting table 1. A first mounting shaft 10 is installed in the first mounting groove 7. A support rod 11 is installed on the first mounting shaft 10. A sleeve 12 is fixedly installed on the top of the support rod 11. A lifting rod 13 is located inside the sleeve 12. A U-shaped fixing block 14 is installed on the top of the lifting rod 13. The U-shaped fixing block 14 is connected to the top of the lifting rod 13 by a pin. A connecting shaft 15 is fixedly installed on the left end of the U-shaped fixing block 14. A guide roller 16 is installed on the connecting shaft 15. A second mounting shaft 17 is located at the bottom of the guide roller 16. Both ends of the second mounting shaft 17 are connected to the inner wall of the second mounting groove 101 by bearings. To cut the angle steel, the first reduction motor 3 is started. The first reduction motor 3 is fixedly mounted on the top of the cutting table 1. The drive shaft of the first reduction motor 3 passes through the fixed plate 2 and is connected to the threaded rod 4. The first reduction motor 3 drives the threaded rod 4 to rotate, which, through engagement with the threaded hole on the push plate 5, moves the push plate 5 to the left side of the cutting table 1, pushing the clamping device 20 upwards. This places the angle steel on the guide roller 16, which is connected to the connecting shaft 15 via a bearing and is positioned below the clamping device 20. The clamping device 20 clamps the angle steel. The first reduction motor 3 is then started, causing it to reverse and move the push plate 5 to the right, pushing the angle steel along the guide roller. When the angle steel reaches the required cutting length, the reduction motor 3 is stopped, and the laser cutting machine 18 is started to cut the angle steel. The first bracket 8 is equipped with a clamping mechanism 20 on its upper part. The clamping mechanism 20 includes a mounting rod 21, a telescopic rod 24 at the top of the mounting rod 21, a spring 23 sleeved on the telescopic rod 24, and a clamping wheel 22 at the bottom of the mounting rod 21. The top of the telescopic rod 24 is fixedly installed on the first bracket 8. The clamping wheel 22 and the mounting rod 21 are connected by a pin. After the angle steel is placed on the guide roller 16, the spring 23 pushes the mounting rod 21 to move downward, the telescopic rod 24 extends, and the mounting rod 21 drives the clamping wheel 22 to move downward, clamping the angle steel to facilitate cutting the angle steel.

[0016] The right half of the sleeve 12 is provided with a mounting hole 121, and the left half of the sleeve 12 is provided with a threaded hole 122.

[0017] The lifting rod 13 is provided with through holes 131, and there are three sets of through holes 131. By rotating the bolt 123 and removing the bolt 123, the U-shaped fixing block 14 is moved upward. The U-shaped fixing block 14 drives the lifting rod 13 to move upward or downward. The U-shaped fixing block 14 pushes the connecting shaft 15 to rotate, changing the angle of the guide roller 16. The two ends of the first mounting shaft 10 are installed in the first mounting groove 7 through bearings. The lifting rod 13 and the sleeve 12 rotate on the first mounting shaft 10 through the support rod 11 to adjust the angle of the guide roller 16. This cutting device cuts angle steel at different angles. After the angle of the guide roller 16 is adjusted, the through holes 131 provided on the lifting rod 13 are aligned with the mounting holes 12. The mounting bolts 123 fix the lifting rod 13, thus completing the fixation of the guide roller 16.

[0018] The upper part of the second bracket is provided with a connecting groove 25, and a connecting rod 26 is provided in the connecting groove 25. A lead screw 27 is provided in the middle of the connecting rod 26. The transmission shaft of the second reduction motor 19 passes through the side of the second bracket 9 and is connected to the lead screw 27. A threaded hole that mates with the lead screw 27 is provided in the middle of the connecting rod 16. The second reduction motor 19 drives the lead screw 27 to rotate, and the lead screw 27 moves the connecting rod 26 by mates with the threaded hole. The connecting rod 26 drives the laser cutting machine 18 to move and cut the angle steel.
