Description

Technical Field

[0001] The present invention relates to the technical field of angle steel processing, and specifically to an integrated production line for laser marking and cutting of angle steel. Background Art

[0002] In modern industrial production, angle steel, as a commonly used profile, is widely used in many fields such as construction, bridges, machinery manufacturing, and power facilities. With the continuous improvement of product precision, production efficiency, and personalized requirements in various industries, higher requirements are put forward for the processing quality and efficiency of angle steel.

[0003] In the traditional angle steel processing process, marking and cutting are often carried out separately and need to be completed sequentially on different equipment. This production method not only has cumbersome processes, resulting in a long production cycle, but also easily causes damage to the surface of the angle steel during the process of multiple transfers of the angle steel, affecting the product quality. At the same time, multi-equipment operation increases the labor cost and the floor area of the equipment, reducing the economic benefits of the enterprise.

[0004] To solve these problems, an integrated production line for laser marking and cutting of angle steel has emerged in the prior art, attempting to integrate the marking and cutting processes to improve production efficiency and product quality. However, the current integrated production line still has many defects. Firstly, its adaptability to angle steel of different specifications and different flatness is poor. When encountering curved or uneven angle steel, it is difficult to ensure the accuracy of the marking position and the cutting precision. Secondly, during the laser marking and cutting process, there is a lack of an effective linkage control mechanism, and it is impossible to adjust the marking and cutting parameters in real time according to the actual situation of the angle steel, resulting in unstable processing quality. Summary of the Invention

[0005] The purpose of the present invention is to provide an integrated production line for laser marking and cutting of angle steel to solve the problems raised in the above background art.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In the present invention, the detection assembly, through the cooperation of the detection rod, pulley, displacement sensor and data processor in the detection box, can perceive the bending and unevenness conditions on the surface of the angle steel in real time, providing accurate data support for subsequent processing. The linkage structure composed of the tool, the first rack, the transmission gear and the second rack automatically removes the burrs on the surface of the angle steel before detection, ensuring that the pulley can accurately fit the contour of the angle steel and improving the detection accuracy. Based on the detection data, the position adjusting assembly accurately controls the displacement of the laser through the first linear module and the second linear module, and at the same time adjusts the parameters in combination with the processing requirements, realizing high-precision marking and cutting operations, and effectively avoiding processing errors caused by unevenness or position deviation of the angle steel surface.

[0022] 2. In the present invention, from the transportation, positioning, and detection of angle steel to marking and cutting, the entire production process achieves a high degree of automation. Under the coordination of the central control system, each component operates automatically according to the preset program and detection data, reducing manual intervention. For example, when the tool wears, the automatic adjustment system composed of a conductive ring, conductive wire, control switch, electromagnetic lock sleeve, and return spring can monitor and automatically adjust the tool position in real time to ensure the continuous and stable operation of the production line. This not only improves production efficiency, shortens the processing cycle, but also reduces labor costs and enhances the economic benefits of the enterprise.

[0023] 3. In the present invention, the electromagnet provides magnetic repulsive force for the tool rod, enhancing the stability of the tool during operation, preventing it from retracting due to external forces during processing, and ensuring the continuity of burr removal work. The protective box encloses the processing area, effectively blocking the sparks and debris generated by laser processing and protecting the safety of operators; the control console integrates control and monitoring functions, facilitating operators to grasp the operation status of the production line in real time and handle abnormal situations promptly. The design of the blanking port and blanking pipeline realizes the automatic collection and transportation of waste materials and processed angle steel, keeping the working environment clean and orderly, and further ensuring the stable operation of the production line.

[0045] Refer to Figure 3 , a blanking port is opened on the top of the processing table 1. A blanking pipe is connected at the blanking port.

[0046] Working principle:

[0047] Conveying link: The conveying component is the starting link of the entire production line. The first adjusting screws 18 and the sliding seats 20 on both sides of the conveying frame 17 can adjust the position and spacing of the conveyor belts 21 according to the specifications of the angle steel to form a suitable conveying channel. In this way, angle steels of different specifications can be smoothly conveyed to the lower part of the laser 16 on the processing table 1 through the conveyor belts 21, preparing for subsequent processing.

[0048] Limiting link: After the angle steel reaches the processing position, the limiting component starts to function. The driving motor 7 drives the three-jaw chuck 6 to act on the support table 5 to firmly clamp the angle steel. At the same time, the first cylinder 10 and the second cylinder 12 on the support plate 8 respectively push the first guide roller 9 and the second guide roller 11 towards the center of the through hole, further limiting the angle steel. Multiple limiting components work together to ensure the stable position of the angle steel during processing and prevent it from shifting or shaking.

[0049] Detection link: The pushing component is the starting driving part of the detection link. When the angle steel is conveyed by the conveying component to the lower part of the laser 16 on the processing table 1 and fixed by the limiting component, the control system issues an instruction to the pushing component. First, the first push rod 23 starts, pushing the mounting seat 24 to slide along a predetermined track on the bearing plate 22 to move the mounting seat 24 to a suitable lateral position. Then, the second push rod 25 starts, and its driving end pushes the detection box 26 towards the outer wall of the angle steel until the detection box 26 reaches the predetermined detection position, at which time the pulley 27 on the detection box 26 gently contacts the surface of the angle steel.

[0050] When the detection box 26 is in the initial state, the support spring 33 inside is in a pre-compressed state. One end of the support spring 33 is connected to the slide plate 32 on the side wall of the detection rod 29, and the other end is connected to the inner wall of the detection box 26. This pre-compressed state makes the support spring 33 generate an outward elastic force, prompting the detection rod 29 to have a tendency to slide out of the detection box 26. A pulley 27 is installed at the end of the detection rod 29 extending outside the detection box 26. When the detection box 26 is pushed to contact the surface of the angle steel, the pulley 27 closely adheres to the outer surface of the angle steel under the elastic force of the support spring 33. The design of the pulley 27 can not only reduce the friction with the surface of the angle steel to ensure that it can roll smoothly along the undulation of the angle steel surface, but also avoid damaging the surface of the angle steel during the contact process.

[0051] When the angle steel is bent or the surface is uneven, as the angle steel moves during transportation, the pulley 27 will roll along the contour of the angle steel surface. Due to the undulation of the angle steel surface, the pulley 27 will drive the detection rod 29 to slide correspondingly inside the detection box 26. If the surface of the angle steel is convex, the pulley 27 will be pushed up, driving the detection rod 29 to slide into the detection box 26, and at this time the support spring 33 will be further compressed; if the surface of the angle steel is concave, the elastic force of the support spring 33 will push the detection rod 29 and the pulley 27 to slide out of the detection box 26 to keep the pulley 27 in close contact with the angle steel surface.

[0052] During the sliding process of the detection rod 29, the displacement sensor 38 installed on the side wall of the detection rod 29 will detect the displacement of the detection rod 29 in real time. The displacement sensor 38 can adopt a high-precision linear displacement sensor, which can accurately measure the tiny displacement changes of the detection rod 29. The displacement sensor 38 transmits the detected displacement data to the data processor 39 in the form of an electrical signal in real time.

[0053] After receiving the displacement data transmitted by the displacement sensor 38, the data processor 39 will perform a series of processing and analysis on these data. Then, the data processor 39 will convert the displacement data into the shape information of the angle steel surface according to the preset algorithm. By calculating the change rate of the displacement data, the bending degree and bending direction of the angle steel surface can be judged; by performing integral processing on the displacement data, the overall contour information of the angle steel surface can be obtained.

[0054] The data processor 39 will compare the shape information of the angle steel surface obtained after processing and analysis with the preset standard shape data. If it is found that the shape deviation of the angle steel surface exceeds the allowable range, the data processor 39 will mark these deviation information and transmit it to the central control system.

[0055] After receiving the shape deviation information of the angle steel surface transmitted by the data processor 39, the central control system will conduct comprehensive analysis on these information. The central control system will determine the position and parameters that the laser 16 needs to be adjusted according to the bending degree, bending position of the angle steel and the preset processing requirements. For example, if there is a large bend in a certain position of the angle steel, the central control system will judge that it is necessary to adjust the horizontal and vertical positions of the laser 16 to ensure that the laser can accurately act on the processing part of the angle steel.

[0056] Based on the analysis results, the central control system issues a control command to the position adjustment component. The position adjustment component consists of a support rod 13 vertically installed on the top surface of the processing table 1, a first linear module 14 horizontally installed on the support rod 13, and a second linear module 15 vertically installed on the first linear module 14.

[0057] When it is necessary to adjust the horizontal position of the laser 16, the central control system will control the first linear module 14 to start. The motor inside the first linear module 14 drives the lead screw to rotate, and the lead screw drives the slider to slide on the guide rail, thereby driving the laser 16 installed on the second linear module 15 to move horizontally. The moving distance and direction are precisely controlled according to the instructions of the central control system to ensure that the laser 16 can be aligned with the bending part of the angle steel.

[0058] When it is necessary to adjust the vertical position of the laser 16, the central control system will control the second linear module 15 to start. Similarly, the motor inside the second linear module 15 drives the lead screw to rotate, and the lead screw drives the slider to slide on the guide rail, so that the laser 16 moves in the vertical direction. Through the coordinated actions of the first linear module 14 and the second linear module 15, the laser 16 can be accurately adjusted to the appropriate position on the two-dimensional plane.

[0059] In addition to adjusting the position of the laser 16, the central control system will also adjust the processing parameters of the laser 16 according to the bending degree and surface condition of the angle steel. For example, if the bent part of the angle steel is thicker or the surface is uneven, the central control system will appropriately increase the power of the laser to ensure sufficient cutting or marking depth; if the curvature of the bent part is large, the central control system will adjust the scanning speed and scanning path of the laser to ensure the accuracy and quality of processing.

[0060] After adjusting the position and processing parameters of the laser 16, the laser 16 starts to perform marking or cutting processing on the angle steel according to the predetermined program. During the processing, the detection component will continue to monitor the surface condition of the angle steel in real time, and the central control system will fine-tune the position and parameters of the laser 16 according to the feedback information to ensure the accuracy and stability of the entire processing process.

[0061] Processing link: The positioning component controls the position of the laser 16. The first linear module 14 and the second linear module 15 work together, enabling the laser 16 to move flexibly on the two-dimensional plane of the processing table 1 to reach the designated marking and cutting positions. At the same time, according to the angle steel surface condition data fed back by the detection component, the marking and cutting parameters of the laser 16 can be adjusted to achieve precise processing.

[0062] In the detection link of the integrated production line for angle steel laser marking and cutting, the coordinated work of the tool 28 and the electromagnet 37 plays a key role in improving the detection accuracy and ensuring the processing stability.

[0063] When the detection box 26 approaches the angle steel under the action of the pushing component, before the pulley 27 on the detection rod 29 contacts the surface of the angle steel, the cutter 28 begins to function. Since there are often unevenness such as burrs and protrusions on the surface of the angle steel during production or transportation, these defects will interfere with the normal rolling of the pulley 27, resulting in deviation of the displacement data of the detection rod 29, and thus affecting the detection accuracy. At this time, the detection rod 29 and the tool rod 30 form a linkage relationship through the transmission structure composed of the first rack 34, the transmission gear 35 and the second rack 36. In the initial state, the tip of the cutter 28 and the outer edge of the pulley 27 are on the same horizontal line. When the detection box 26 moves towards the angle steel, even if the sliding of the detection rod 29 caused by the bending of the angle steel has not been triggered, the cutter 28 will contact the surface of the angle steel first as the detection box 26 advances. The cutter 28 cuts off or scrapes the uneven parts such as burrs and protrusions on the surface of the angle steel, making the surface of the angle steel relatively flat. In this way, when the pulley 27 contacts the surface of the angle steel subsequently, it can fit more accurately with the actual contour of the angle steel. As the surface of the angle steel fluctuates and drives the detection rod 29 to slide, the data obtained by the displacement sensor 38 can more truly reflect the bending condition of the angle steel, thus significantly improving the detection accuracy.

[0064] The electromagnet 37 plays a role in stabilizing the working state of the cutter 28 during the entire processing process. During the cutting of the angle steel, factors such as the vibration and impact force generated by laser cutting, or the uneven material of the angle steel itself, may cause an external force that makes the tool rod 30 slide inward into the detection box 26. Once the tool rod 30 slides inward, the position of the cutter 28 will change, not only unable to continue to effectively process the surface of the angle steel, but also may affect the normal progress of laser marking and cutting, and even damage the equipment. At this time, after the electromagnet 37 is energized, it generates magnetism and applies a magnetic repulsive force to the tool rod 30. This magnetic repulsive force counteracts the external force that may cause the tool rod 30 to slide inward, provides a stable resistance for the tool rod 30, keeps it in the current position, ensures that the cutter 28 is firmly in the working state, continuously processes the possible defects on the surface of the angle steel, and at the same time guarantees the stability and safety of the entire processing process.

[0065] When the integrated production line for laser marking and cutting of angle steel is ready to process the angle steel, each component starts to run according to the preset program. The power supply module 31 is turned on to provide electrical energy for the conductive ring 40 on the pulley 27, making the entire pulley 27 in a charged state. This power supply process is the basis for the subsequent realization of the automatic adjustment function of the cutter.

[0066] When the conveying component transports the angle steel to a suitable position below the laser 16 on the processing table 1 and the limiting component effectively fixes the angle steel, the pushing component starts to act. The first push rod 23 and the second push rod 25 in the pushing component cooperate to push the detection box 26 towards the outer wall of the angle steel. As the detection box 26 approaches, the pulley 27 first contacts the surface of the angle steel. Since the conductive loop 40 is charged, electrical energy is transferred to the angle steel through the contact point between the conductive loop 40 and the angle steel.

[0067] As a conductor, the angle steel conducts electrical energy to the conductive wire 41 inside the cutting tool 28 in contact with it. The conductive wire 41 further transfers the electrical energy to the control switch 44 in the detection box 26. After receiving the electrical energy signal, the internal circuit of the control switch 44 triggers the corresponding control logic and outputs an energization command to the electromagnetic lock sleeve 43. After the electromagnetic lock sleeve 43 is energized, it generates a magnetic field, which interacts with the permanent magnet column 42 to firmly lock the permanent magnet column 42 in its current position, making the cutting tool 28 fixed on the permanent magnet column 42 also remain stable. At this time, the cutting tool 28 can normally remove the burrs on the surface of the angle steel, providing a flat surface of the angle steel for subsequent detection and processing steps.

[0068] During the continuous operation of the production line, the cutting tool 28 continuously cuts the burrs on the surface of the angle steel, and its cutting edge will gradually wear. When the wear degree of the cutting tool 28 reaches a certain value, the tip of the cutting tool 28 will no longer be able to maintain close contact with the outer wall of the angle steel. At this time, the conductive path originally formed between the conductive loop 40 and the cutting tool 28 through the angle steel is cut off.

[0069] Since no electrical energy is transferred to the conductive wire 41 through the angle steel, the control switch 44 does not receive the electrical energy input signal. The detection circuit inside the control switch 44 will continuously monitor the state of the input signal. Once it detects a signal interruption, it will determine that the cutting tool 28 has worn and cannot normally contact the outer wall of the angle steel, and then trigger the subsequent automatic adjustment mechanism.

[0070] When the control switch 44 detects that the conductive path is interrupted due to the wear of the cutting tool 28, it immediately changes its output state and cuts off the power supply to the electromagnetic lock sleeve 43. After the electromagnetic lock sleeve 43 is powered off, the magnetic field it generates disappears, and the locking effect on the permanent magnet column 42 is released.

[0071] A return spring 45 is sleeved outside the permanent magnet column 42. When the electromagnetic lock sleeve 43 locks the permanent magnet column 42, the return spring 45 is in a compressed state and stores elastic potential energy. When the electromagnetic lock sleeve 43 loses its magnetism, the return spring 45 starts to release the elastic potential energy, and the generated elastic force pushes the permanent magnet column 42 to slide outward from the electromagnetic lock sleeve 43. Since the cutting tool 28 is fixedly connected to the permanent magnet column 42, the sliding of the permanent magnet column 42 will drive the cutting tool 28 to move towards the angle steel together until the cutting tool 28 fits the outer wall of the angle steel again.

[0072] When the tool 28 re - adheres to the outer wall of the angle steel under the elastic force of the return spring 45, the conductive ring 40 and the angle steel form a conductive path again. Electric energy is then transmitted through the angle steel to the conductive wire 41 and delivered to the control switch 44.

[0073] After receiving the electric energy signal, the control switch 44 triggers the internal control logic again and outputs a power - on command to the electromagnetic lock sleeve 43. The electromagnetic lock sleeve 43 is re - energized to generate a magnetic field, locking the permanent magnet column 42 in the current position again, so that the tool 28 is stably maintained in the working state of adhering to the angle steel. In this way, the tool 28 can continue to remove the burrs on the surface of the angle steel, avoiding the influence of tool 28 wear on the detection accuracy and processing quality of the entire production line.

[0074] Through the above - mentioned series of work processes, the system realizes the real - time monitoring and automatic adjustment functions of the wear condition of the tool 28, ensuring that the integrated production line of angle steel laser marking and cutting can operate continuously, stably and efficiently.

[0075] Waste treatment and protection operations: During the processing, the generated waste or the cut part of the angle steel enters the blanking pipeline through the blanking port at the top of the processing table 1, realizing automatic collection and transportation. The protection box 2 covers the top of the processing table 1 to prevent the sparks and debris generated by laser processing from splashing, ensuring the safety of the operators. The operators can set processing parameters, start or stop the production line, etc. through the control console 4.

[0076] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present invention itself. Various changes can be made in its form and details without departing from the spirit and scope of the present invention defined by the appended claims.
