Description

Technical Field

[0001] The present application relates to the technical field of laser cutting equipment manufacturing, and in particular to a laser cutting equipment for channel steel template processing. Background Art

[0002] Channel steel module is a structural module formed by combining or processing channel steel materials. It is widely used in construction, industrial equipment installation, machinery manufacturing and other engineering fields. This module has greatly improved the efficiency of engineering construction and machinery manufacturing due to its easy installation and strong versatility. In the production process of channel steel modules, laser cutting equipment has become an indispensable tool with its efficient and precise processing capabilities. Laser cutting can accurately process channel steel into specific lengths, shapes or connection forms to meet various complex engineering needs.

[0003] Laser cutting equipment usually consists of a laser, an optical transmission system, a cutting head, a workbench and a chuck system, a control system, and a cooling and exhaust system. The laser is responsible for generating a high-energy laser beam, the optical transmission system and the cutting head realize precise focusing and cutting operations of the laser beam, the workbench and the chuck system are responsible for fixing and moving the workpiece, and the control system ensures the accuracy and automation of the cutting process. At present, the chuck system in most channel steel laser cutting equipment uses a four-claw self-centering chuck to fix the channel steel. The clamping roller on the chuck firmly clamps the channel steel with a certain pressure to ensure the stability of the material and the accuracy of the cutting during the processing. In order to improve the clamping efficiency and convenience, the clamping roller on the chuck is usually made of metal material, and its surface is precisely processed to maintain the clamping stability and smooth material transportation.

[0004] In actual applications, in order to reduce the impact of sputtering, some laser cutting equipment will add protective devices to protect the key components of the cutting equipment. However, the protective devices are often mainly concentrated around the cutting head to ensure the accuracy and efficiency of the laser cutting of the channel steel. However, the high-temperature jet and slag generated during the cutting process are unpredictable, and the clamping roller is directly exposed to the high-temperature environment generated by laser cutting, which makes its surface prone to local ablation, unevenness or depression. These defects will cause damage to the surface of the clamping roller, thereby affecting the fixing effect and conveying accuracy of the channel steel, and then increase the equipment maintenance cost and downtime, affecting production efficiency. Summary of the invention

[0005] The present application provides a laser cutting device for processing channel steel templates. When laser cutting the channel steel, the laser cutting device can effectively protect the chuck from being damaged by the high-temperature jet and slag generated by the cutting. At the same time, the laser cutting device can detect in real time whether the chuck is damaged during use, and can make corresponding adjustments to ensure accurate and efficient cutting operations of the laser cutting device.

[0006] The laser cutting equipment for channel steel template processing provided in this application adopts the following technical solution: A laser cutting device for processing a channel steel template, comprising: Workbench; A cutting assembly, the cutting assembly comprising a cutting head and a laser generator, the cutting head being arranged on the workbench, and the laser generator being arranged on the cutting head; A chuck assembly, wherein the chuck assembly is arranged on the workbench, the chuck assembly is located below the cutting head, the chuck assembly comprises a disc body and a clamping roller, the disc body is arranged on the workbench, a sliding groove is provided on the disc body, the sliding seat is slidably arranged in the sliding groove, and the clamping roller is rotatably arranged on the sliding seat; A protection component, wherein the protection component is arranged on the sliding seat, and the protection component includes a baffle and a transmission member, wherein the baffle is slidably arranged on the sliding seat, and the transmission member is arranged on the sliding seat, and when the sliding seat slides on the disk body, the baffle can slide back and forth on the sliding seat through the transmission member, so that when the clamping roller clamps the fixed channel steel, the baffle automatically covers the sliding seat, and the baffle can block the high-temperature jet and slag generated by laser cutting from splashing onto the sliding seat.

[0007] By adopting the above technical scheme, the baffle and transmission parts arranged on the sliding seat can realize automatic covering of the sliding seat by the baffle during the cutting process while the chuck assembly is tightened and fixed, so as to prevent the high-temperature jet and slag generated by laser cutting from directly splashing onto the sliding seat. Some existing laser cutting equipment will also be provided with a baffle on the chuck to block the high-temperature jet and slag, but these baffles are fixed on the chuck. The shape and size of these baffles fixed on the chuck not only need to match the workpiece to be processed, but also are difficult to cope with workpieces of multiple specifications or special shapes. Once the baffle is set too large or the installation position is close to the cutting area, it will also affect the movement range and cutting efficiency of the laser beam. In the present technical scheme, the baffle moves with the movement of the sliding seat to ensure that the baffle can protect the key area and there will be no loss of protection due to mismatch of position fixation. This not only protects the sliding seat and the clamping roller, and extends the service life of the chuck, but also reduces the possibility of chuck equipment failure caused by high-temperature jet, and improves the reliability of the operation of the laser cutting equipment.

[0009] By adopting the above technical solution, using a servo motor to drive the active gear, combined with a multi-stage transmission design of a driven gear, a secondary gear and a transmission gear, the sliding seat can perform smooth and high-precision reciprocating sliding on the disk body, effectively ensuring the positioning accuracy of the channel steel template during the cutting process, thereby improving the processing quality; in addition, the multi-stage gear transmission structure optimizes the power transmission efficiency while reducing the overload impact that may be caused by direct transmission, ensuring the smooth operation of the drive system and extending the service life of the equipment.

[0010] Optionally, the transmission member includes a linkage rack, a linkage gear, a connecting shaft, a driving pulley, a driven pulley and a transmission belt, the sliding seat is provided with a bearing portion, the bearing portion is provided with a rotating seat, the clamping roller is rotatably arranged on the rotating seat, the bearing portion is provided with an avoidance groove, the linkage gear is arranged in the avoidance groove, the linkage rack is slidably arranged on the inner wall of the avoidance groove, and one end of the linkage rack is fixedly connected to the side of the rotating seat away from the clamping roller, the rotating seat is slidably arranged on the bearing portion through the linkage rack, the connecting shaft is rotatably passed through the bearing portion, the driving pulley and the driven pulley are both arranged on a side of the bearing portion away from the disk body, and one end of the connecting shaft is connected to the connecting The driven gear is fixedly connected, and the other end of the connecting shaft is fixedly connected to the driving pulley, the linkage gear is meshed with the linkage rack, and the driven pulley is rotatably arranged on the bearing part, and the transmission belt is wound around the driving pulley and the driven pulley, and a connecting part is fixedly provided on the transmission belt, and a guide rail is fixedly provided on the side of the bearing part facing away from the disk body, and a slider and a toggle block are fixedly provided on the baffle, and the baffle is slidably arranged on the bearing part through the slider, and the connecting part is fixedly connected to the toggle block, and when the clamping roller abuts against the channel steel, the baffle can slide back and forth on the bearing part through the transmission belt, so that the baffle can automatically cover the sliding seat, thereby protecting the clamping roller from being damaged by cutting and spattering.

[0011] By adopting the above technical solution, using the transmission coordination of the linkage rack, linkage gear, connecting shaft, active pulley, driven pulley and transmission belt, the baffle can automatically slide back and forth on the bearing part when the clamping roller abuts against the channel steel, and the whole process of dynamic shielding of the sliding seat can be achieved without human intervention, effectively avoiding the damage of the high-temperature jet and slag generated by laser cutting to the sliding seat and the clamping roller, and improving the automation level and safety of the processing process; and the meshing of the linkage rack and the linkage gear combined with the cyclic movement of the transmission belt ensures that the movement of the baffle is completely synchronized with the position change of the sliding seat, avoiding the problem of untimely protection caused by transmission delay, and improving the reliability of equipment operation. and cutting efficiency; an avoidance groove is opened on the bearing part to accommodate the linkage rack and the linkage gear, so that the transmission structure is compact and no extra space is wasted, while avoiding the interference of the transmission parts with the operation of the sliding seat and the clamping roller, thereby improving the rationality of the overall layout of the equipment; in addition, since the baffle starts to slide on the bearing part only when the clamping roller abuts against the channel steel, this means that only after the clamping roller is fully clamped in place, the baffle just completely covers the bearing part and the sliding seat, which greatly improves the versatility of the equipment, and there will be no lack of protection due to mismatch of position fixation, which will cause the chuck to cause equipment failure due to high-temperature jet, thereby improving the reliability of laser cutting equipment operation.

[0012] Optionally, the protection component also includes a correction piece, which includes a piston cylinder, a display tube and an abutment roller. A mounting groove is provided on the side of the baffle away from the sliding seat. The piston cylinder is fixed in the mounting groove. A piston block is slidably arranged in the piston cylinder. The piston block separates the piston cylinder into two independent chambers. The two independent chambers are respectively arranged as a hydraulic chamber and an extrusion chamber. Hydraulic oil is injected into the hydraulic chamber. The display tube is fixed at one end of the piston cylinder close to the hydraulic chamber. The display tube is connected to the hydraulic chamber, and the diameter of the display tube is much smaller than that of the piston cylinder. The cylinder diameter is , and the display tube is provided with a scale; a connecting rod is fixedly provided at one end of the piston block located in the extrusion chamber, a give way groove is opened at one end of the baffle plate close to the clamping roller, and the connecting rod extends into the give way groove at one end away from the piston cylinder, and an abutment seat is fixedly provided at one end of the connecting rod located in the give way groove, and the abutment roller is rotatably arranged on the abutment seat, and when the clamping roller is clamping the fixed channel steel, the abutment roller abuts against the channel steel under the drive of the baffle plate, so that the piston block slides in the piston cylinder, and the display tube displays the displacement of the abutment roller.

[0013] By adopting the above technical solution, the piston cylinder and the abutment wheel in the correction part are linked together. When the channel steel is clamped and fixed, the abutment roller abuts against the channel steel and moves the abutment roller into the yielding groove. The display tube can feedback the displacement information, provide the operator with intuitive and quantifiable real-time position information of the sliding seat on the chuck, and intuitively display the position of each sliding seat on the disc body, so as to judge whether the channel steel is not clamped correctly. If the sliding distance values ​​of the piston blocks displayed by the two sets of display tubes on the disc body are consistent at the beginning of each clamping, it indicates that the clamping position of the channel steel is correct. At the same time, it can also be judged whether the chuck assembly is damaged, avoiding cutting errors caused by the offset of the installation position of the channel steel, and significantly improving the cutting accuracy. In addition, the correction part can also monitor in real time whether the entire channel steel to be cut is bent, that is, the clamping roller clamps and fixes the channel steel, adjusts the channel steel to the correct position, and then transports the channel steel from the beginning to the end from the clamping tube. During this period, according to the fluctuation of the liquid level on the display tube, it can be judged whether the channel steel itself is bent, which increases the versatility and practicality of the equipment.

[0014] Optionally, a certain amount of air is injected into the display tube to divide the display tube into three groups of display areas of different colors at equal intervals. The three groups of display areas are respectively arranged as a red display area, a green display area and a yellow display area. The yellow display area is located at one end of the display tube close to the piston cylinder, the red display area is located at one end of the display tube away from the piston cylinder, and the green display area is located between the yellow display area and the red display area. When the hydraulic oil in the hydraulic chamber is squeezed by the piston block, a part of the hydraulic oil enters the display tube, so that the position change of the abutment wheel can be displayed by the liquid level position of the hydraulic oil in the display tube.

[0015] By adopting the above technical solution, three different color display areas of red, yellow and green are set in the display tube, and the position status of the abutment roller is intuitively indicated by the movement of the hydraulic oil level. When the liquid level is in the green display area, it means that the position of the channel steel is in the safe processing range, and the operator does not need to worry about the equipment operation deviation; if the liquid level enters the red or yellow display area, it will warn that there may be position deviation or abnormal situation, reminding the operator to make timely adjustments. This multi-segment indication method improves the intuitiveness and safety of equipment operation; at the same time, using the Pascal principle of fluid mechanics, the display tube is connected to the hydraulic cavity, and the height change of the hydraulic oil level directly reflects the slight position change of the channel steel, avoiding the accumulation of errors during the processing process. Compared with the traditional method that relies on mechanical scales or manual observation, this design is more accurate and real-time.

[0016] Optionally, the baffle is also provided with a cleaning piece, the cleaning piece includes a compressed gas cylinder, an exhaust pipe and a jet group. A placement groove is opened on a surface of the baffle close to the sliding seat, the compressed gas cylinder is arranged in the placement groove, one end of the compressed gas cylinder is an operating end, and the other end of the compressed gas cylinder is an output end. The operating end of the compressed gas cylinder is fixedly connected to the toggle block, one end of the exhaust pipe is connected to the output end of the compressed gas cylinder, the jet group is arranged at an end of the exhaust pipe away from the compressed gas cylinder, and the jet group is embedded in an end of the baffle close to the clamping roller. When the baffle slides on the sliding seat, the toggle block squeezes the operating end of the compressed gas cylinder, and the compressed gas cylinder sprays air outwardly through the jet group, thereby realizing jet cleaning of the end of the baffle close to the clamping roller.

[0017] By adopting the above technical scheme, a fully automatic cleaning function is realized by utilizing a combination of a compressed air cylinder, an exhaust pipe and an air jet group. When the baffle slides, the compressed air cylinder is compressed by the toggle block, and a high-pressure airflow is released through the air jet group to automatically remove dust, slag and other impurities generated by laser cutting on and around the baffle. This process does not require manual cleaning, which not only reduces labor intensity but also improves processing efficiency. At the same time, the cleaning part can complete the cleaning action during each reciprocating process of the baffle sliding, avoiding the baffle slide rail from getting stuck or the clamping roller and abutting roller from wearing due to slag accumulation. It has extremely high timeliness and coverage, effectively protects the key moving parts of the equipment, and improves the overall durability of the equipment.

[0018] Optionally, the jet group includes a connecting pipe and a nozzle, the connecting pipe is fixed at one end of the exhaust pipe away from the compressed air cylinder, the connecting pipe is communicated with the exhaust pipe, and the nozzle is fixed on the connecting pipe. The jet groups are provided with two groups, and the jet directions of the nozzles in the two groups of the jet groups are vertically cross-arranged, the jet direction of one group of the jet groups is toward the abutment roller, and the jet direction of the other group of the jet groups is toward the clamping roller.

[0019] By adopting the above technical solution, the two groups of jet groups are set to face different positions, one group facing the abutment roller and the other group facing the clamping roller. This layout ensures the cleaning of the residues of the two key components in the channel steel cutting process, avoids the accumulation of dust affecting the accuracy or damaging the clamping and correction components, and improves the stability and life of the equipment operation.

[0020] Optionally, the correction member further includes a return spring, which is disposed in the hydraulic chamber, one end of the return spring is fixedly connected to the piston block, and the other end of the return spring is fixedly connected to the inner wall of the hydraulic chamber.

[0021] By adopting the above technical solution, a reset spring is set in the hydraulic chamber, which can quickly push the piston block back to its position after the abutment roller is separated from the channel steel, ensuring that the correction part is restored to its initial state and ready for the next processing cycle. This not only avoids the reset lag problem that may be caused by the separate control of the hydraulic system, but also provides a stable reset force, ensuring the continuity and reliability of the equipment operation, and improving the adaptability of the equipment.

[0022] Optionally, an adjusting member is provided on the sliding seat, and the adjusting member includes an adjusting screw and a connecting block. A bearing portion is provided on the sliding seat, a rotating seat is fixed on the bearing portion, the clamping roller is rotatably set on the rotating seat, the connecting block is fixed on the sliding seat, an adjusting groove is opened on the bearing portion, the adjusting screw is rotatably set in the adjusting groove, the connecting block is threadedly connected to the adjusting screw, and rotating the adjusting screw can adjust the relative position between the bearing seat and the sliding seat.

[0023] By adopting the above technical solution, the relative position between the bearing seat and the sliding seat can be accurately adjusted by using the adjusting screw rod arranged between the sliding seat and the bearing portion. The fine-tuning ability of the adjusting screw rod can accurately locate the working position of the clamping roller, thereby ensuring that the channel steel is always in the correct processing position when clamping, avoiding cutting errors caused by improper clamping position.

[0024] Optionally, a scraper is provided on the disk body, and support parts are fixed at both ends of the scraper in the length direction, and one end of the support part away from the scraper is fixed on the disk body. The scraper is mounted above the baffle through the support part, and one side of the scraper in the width direction abuts against a side of the baffle away from the bearing part. When the baffle slides back and forth on the sliding seat, the scraper can clean the surface of the baffle.

[0025] By adopting the above technical solution, the scraper is arranged above the baffle, and can clean the surface of the baffle during the reciprocating sliding of the baffle, effectively avoiding the accumulation of residues and dust on the surface of the baffle, which may cause the baffle to slide poorly or reduce the protective performance. It not only keeps the baffle clean and ensures that the baffle is not contaminated by dust, slag or other impurities generated during the laser cutting process, thereby ensuring its operating stability and accuracy during high-speed sliding, but also can reduce the frequency of manual cleaning through the real-time cleaning mechanism, thereby improving the continuous operation capability of the equipment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The baffle and transmission member arranged on the sliding seat realize automatic covering of the sliding seat by the baffle during the cutting process while the chuck assembly is tightened and fixed, so as to prevent the high-temperature jet and slag generated by laser cutting from directly splashing onto the sliding seat. Some existing laser cutting equipment also sets a baffle on the chuck to block the high-temperature jet and slag, but these baffles are fixed on the chuck. The shape and size of these baffles fixed on the chuck not only need to match the workpiece to be processed, but also are difficult to cope with workpieces of multiple specifications or special shapes. Once the baffle is set too large or the installation position is close to the cutting area, it will also affect the movement range and cutting efficiency of the laser beam. In the present technical scheme, the baffle moves with the movement of the sliding seat to ensure that the baffle can protect the key area and there will be no loss of protection due to mismatch of position fixation. This not only protects the sliding seat and the clamping roller, but also prolongs the service life of the chuck, but also reduces the possibility of chuck equipment failure caused by high-temperature jet, and improves the reliability of laser cutting equipment operation. 2.

[0055] Reference Figure 4 , Figure 5 and Figure 6 In the embodiment of the present application, the cleaning member 44 is installed on the baffle 41, and each group of baffles 41 is provided with a group of cleaning members 44, the cleaning member 44 includes a compressed air cylinder 441, an exhaust pipe 442, and an injection group 443, the injection group 443 includes a connecting pipe 4431 and a nozzle 4432, a placement groove 414 is provided on the side of the baffle 41 close to the bearing portion 331, one end of the compressed air cylinder 441 is an operating end, and the other end of the compressed air cylinder 441 is an output end, the compressed air cylinder 441 is fixedly arranged in the placement groove 414, the operating end of the compressed air cylinder 441 is fixedly connected to the toggle block 411, one end of the exhaust pipe 442 is connected to the output end of the compressed air cylinder 441, the connecting pipe 4431 is arranged at one end of the exhaust pipe 442 away from the compressed air cylinder 441, the nozzle 4432 is fixedly arranged on the connecting pipe 4431, and a plurality of groups of nozzles 4432 are provided, and the plurality of groups of nozzles 4432 are arranged and distributed at equal intervals on the connecting pipe 4431.

[0056] The jet group 443 is embedded in one end of the baffle 41 close to the clamping roller 32. There are two jet groups 443. The jet directions of the nozzles 4432 in the two jet groups 443 are vertically crossed. One jet group 443 is directed toward the abutting roller 433, and the other jet group 443 is directed toward the clamping roller 32.

[0057] More specifically, when the controller controls the servo motor 51 to drive the sliding seat 33 to slide on the disk body 31, the clamping roller 32 will gradually abut against the channel steel, so that the connecting rack 421 slides in the avoidance groove 3311, and the connecting gear 422 is engaged with the connecting rack 421. The connecting gear 422 is coaxially connected to the driving pulley 424 through the connecting shaft 423, and the connecting part 4261 is fixedly connected to the toggle block 411, so that the baffle 41 will slide back and forth on the bearing part 331 with the movement of the sliding seat 33, and the baffle 41 adaptively blocks the sliding seat 33, thereby protecting the clamping roller 32 from damage caused by cutting spatter.

[0058] At the same time, since an abutting roller 433 is provided at one end of the baffle 41 close to the clamping roller 32, the abutting roller 433 also abuts against the channel steel when the clamping roller 32 clamps the channel steel, and the guide rod drives the piston block 434 to slide in the piston cylinder 431, so that the display tube 432 displays the displacement of the piston block 434, so that the compression and contraction amount of the abutting roller 433 can be displayed on the display tube 432, and then it can be corrected whether the clamping roller 32 clamps the channel steel correctly. If the sliding distance values ​​of the piston block 434 displayed by the two opposite groups of display tubes 432 on the disk body 31 are consistent at the beginning of clamping each time, it indicates that the clamping position of the channel steel is correct.

[0059] It is worth noting here that the channel steel to be processed is a standard part. Since the sliding seat 33 on the disc body 31 slides synchronously, that is, it gathers inward or expands outward at the same time, when the sliding distance values ​​of the piston block 434 displayed by the two sets of display tubes 432 on the disc body 31 are inconsistent, the reasons for the incorrect clamping of the channel steel are divided into multiple situations. One is that when the sliding distance values ​​of the two sets of display tubes 432 on the disc body 31 are inconsistent, but the liquid levels of the hydraulic oil are both in the green display area, that is, it indicates that the sliding seat 33 is clamped in place, but there is a slight difference in the clamping force of the two sets of clamping rollers 32, but it does not affect the overall processing; Secondly, the sliding distance values ​​of the two groups of display tubes 432 on the plate body 31 are inconsistent. The hydraulic oil level of one group is in the green display area, and the other group is in the yellow display area, which means that one group of clamping rollers 32 has position deviation or excessive wear, resulting in it being unable to effectively clamp the channel steel; Thirdly, the sliding distance values ​​of the two groups of display tubes 432 relative to each other on the disk body 31 are inconsistent. One group of hydraulic oil levels is located in the green display area, while the other group is located in the red display area. This indicates that the clamping position of one group of clamping rollers 32 for the channel steel exceeds the normal state. It is very likely that there are too many cutting residues attached to the clamping rollers 32, which need to be cleaned in time.

[0060] It should be noted here that since the value displayed by the display tube 432 is the clamping force difference between the two groups of clamping rollers 32 after being magnified by the Pascal principle, the clamping difference caused by the sliding seat 33 on the disk body 31 will be more obvious and is not considered here.

[0061] In addition, the correction part 43 can also monitor in real time whether the entire channel steel to be cut has any bending, that is, the clamping roller 32 clamps and fixes the channel steel, adjusts the channel steel to the correct working position, and then transports the channel steel from the beginning to the end from the clamping tube. During this period, if the liquid level on the display tube 432 appears in the red display area or in the yellow display area, it indicates that the channel steel to be cut has bending; if it is always in the green display area, it indicates that the channel steel has no bending.

[0062] When the baffle 41 slides on the sliding seat 33, the connecting part 4261 will squeeze the operating end, the compressed air cylinder 441 will be squeezed, and gas will be discharged from the exhaust pipe 442 on the exhaust end, thereby ejecting air flow outward through the nozzle 4432, and at the same time, the abutment roller 433 and the clamping roller 32 are jet-cleaned to remove any residue that may remain on the abutment roller 433 and the clamping roller 32, thereby achieving cleaning and maintenance of the abutment roller 433 and the clamping roller 32.

[0063] The implementation principle of the laser cutting device for processing channel steel templates in the embodiment of the present application is as follows: one end of the channel steel to be cut is placed in the installation port, and the controller controls the clamping tube to clamp the channel steel. During this period, the baffle 41 slides on the bearing portion 331 as the sliding seat 33 approaches the channel steel. While the clamping roller 32 clamps the channel steel, the abutting roller 433 also abuts the channel steel. The guide rod drives the piston block 434 to slide inward, and the display tube 432 displays the position change of the baffle 41. While the baffle 41 is sliding, the toggle block 411 acts on the operating end of the compressed air cylinder 441, and the gas ejected from the compressed air cylinder 441 is ejected from the nozzle 4432, while the abutting roller 433 and the clamping roller 32 are jet-cleaned; finally, the controller controls the cutting head 21 to perform laser cutting on the channel steel.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
