Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, and specifically relates to a laser cutting device for processing angle steel. Background Technology

[0002] Angle steel, as a commonly used type of steel, is widely used in various industries such as building steel structures, mechanical supports, equipment bases, and cable tray installation. During its processing, laser cutting devices are often used for precise material cutting and slit processing to meet the size requirements of different assembly scenarios. The laser cutting device for angle steel processing achieves precise cutting of angle steel by moving the laser cutting head. At the same time, support plates are used to support the angle steel raw material during the cutting process to ensure cutting stability.

[0003] In practical use, existing laser cutting devices for angle steel processing require manual collection of fragmented plates after cutting, which is inefficient. Cutting fragments are also prone to accidentally remaining between the support plates, making them difficult to clean quickly and causing material discharge blockage. At the same time, the high-temperature molten slag generated by laser cutting tends to adhere to the side walls of the support plates. Long-term accumulation of molten slag will affect the support accuracy of the support plates for the angle steel, thereby reducing the quality of subsequent cutting. Therefore, it is necessary to design a laser cutting device for angle steel processing. Summary of the Invention

[0004] The purpose of this invention is to provide a laser cutting device for angle steel processing that is simple in structure and reasonably designed in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A laser cutting device for angle steel processing includes an outer support, a cutting table mounted on the outer support, a movable module mounted on the outer support, and a laser cutting head mounted on the movable module. Support plates are evenly distributed on the cutting table, and a lower support is slidably connected between the cutting tables. An alignment and lifting mechanism is mounted on the lower support. The alignment and lifting mechanism includes a movable seat slidably connected to the lower support, a return spring between the movable seat and the lower support, a lifting frame slidably connected to the movable seat, an arc-shaped alignment component at the top of the lifting frame, and an alignment block movably connected to the arc-shaped alignment component at the bottom of the cutting table. An eccentric transfer mechanism is mounted on the lifting frame, including a mounting frame fixed on the lifting frame. A drive shaft is evenly rotatably connected to the mounting frame, the drive shaft is connected to a drive mechanism, and a transfer cam is fixedly sleeved on the drive shaft. A shaking mechanism and a cleaning mechanism are mounted on the transfer cam.

[0006] As a further optimization of the present invention, a lifting cylinder is fixedly connected to the movable seat, and the output end of the lifting cylinder is fixedly connected to the lifting frame.

[0007] As a further optimization of the present invention, the driving mechanism includes a closed shell fixed on a mounting bracket, a drive shaft rotatably connected in the closed shell, and a drive motor whose output end is fixedly connected to the drive shaft is provided on the mounting bracket.

[0008] As a further optimization of the present invention, a worm gear is provided on the drive shaft, and a worm wheel located inside the closed shell and meshing with the worm gear is fixedly sleeved at one end of the transmission shaft.

[0009] As a further optimization of the present invention, the shaking mechanism includes a mounting groove formed on the transfer cam, a striking platform slidably connected in the mounting groove, and the striking platform slidably sleeved on the support sleeve.

[0010] As a further optimization of the present invention, a support guide rod fixedly sleeved on the transfer cam is slidably connected in the uniformly opened through grooves of the striking platform, and a storage spring is provided between the transfer cam and the striking platform.

[0011] As a further optimization of the present invention, the support sleeve is rotatably connected to the transmission shaft, and a guide groove is provided on the side wall of the support sleeve. A limit frame is fixed in the groove provided on the side wall of the support sleeve, and the limit frame is fixed on the mounting frame. A guide block fixed on the outer wall of the striking table is slidably connected in the guide groove. The guide groove includes a power storage section, a power release section and a connecting section. The two ends of the connecting section are respectively connected to the power storage section and the power release section, and the power storage section and the power release section are interconnected.

[0012] As a further optimization of the present invention, the cleaning mechanism includes a cleaning disk fixed in the grooves on both sides of the transfer cam, and cleaning brushes are evenly arranged on the cleaning disk.

[0013] As a further optimization of the present invention, the moving module includes a first electric slide rail fixed to one side of the top of the outer support, a transverse frame connected to the slider of the first electric slide rail, the transverse frame being slidably connected to the outer support, a second electric slide rail being provided on the transverse frame, a laser cutting head being fixed to the slider of the second electric slide rail, and a lower support being fixed to the bottom of the transverse frame.

[0014] The beneficial effects of this invention are as follows: 1. The lifting cylinder of this invention drives the lifting frame to move upward. The arc-shaped alignment component at the top of the lifting frame will gradually insert into the slot of the alignment block. With the guidance of the arc surface, the lateral position of the movable seat is automatically corrected. The alignment block and the support plate are spaced at the same distance, ensuring that the eccentric transfer mechanism is accurately embedded in the gap of the support plate and effectively avoiding interference with the support plate during the transfer process.

[0015] 2. The drive mechanism of this invention drives the transmission shaft to rotate, which in turn drives the transfer cam to rotate synchronously. When the transfer cam rotates, the highest point of its outer edge is higher than the upper surface of the support plate. Through periodic pushing and moving actions, the cut fragments are pushed to the limit plate for collection, which is convenient for manual picking later. At the same time, during the rotation of the cam, the cutting fragments that are accidentally piled up between the support plates can be moved and pushed, so that the fragments can be separated from the gap and fall smoothly, avoiding the accumulation and blockage of waste materials.

[0016] 3. When the transfer cam of the present invention rotates, it will simultaneously drive the cleaning disk and cleaning brush in the grooves on both sides to rotate. The cleaning brush makes full contact with the side wall and gap surface of the support plate. During the rotation process, it cleans and peels off the high-temperature slag and metal debris attached to the support plate, and completely removes the residue. This effectively prevents the slag from accumulating on the side wall of the support plate, ensures the cleanliness of the support plate surface, and avoids affecting the subsequent angle steel support and cutting accuracy.

[0017] 4. When the transfer cam of the present invention rotates, it drives the striking table to rotate synchronously through the support guide rod. The guide block on the outer wall of the striking table slides along the guide groove on the support sleeve and passes through the energy storage section, the connecting section and the energy release section in sequence. In the energy storage section, the energy storage spring is compressed to complete the energy storage. After entering the energy release section, the spring releases potential energy to push the striking table to pop out quickly, forming a periodic intermittent knocking on the support plate, causing the waste and slag stuck in the gap of the support plate to loosen and fall off, further improving the cleaning effect and ensuring smooth material discharge.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Please refer to Figures 1-9A laser cutting device for angle steel processing includes an outer support 1, a cutting table 2 fixed inside the outer support 1, a movable module 3 mounted on the outer support 1, and a laser cutting head 4 mounted on the movable module 3. The movable module 3 can drive the laser cutting head 4 to move laterally and longitudinally, thereby cooperating with the laser cutting head 4 to perform cutting. Support plates 5 for supporting angle steel raw materials are evenly arranged on the cutting table 2. The top of the support plates 5 has a serrated structure, which can effectively prevent the cutting heat from accumulating on the angle steel raw materials. A lower support 6 is slidably connected between the cutting tables 2, and an alignment and lifting mechanism 7 is provided on the lower support 6. The alignment and lifting mechanism 7 includes a movable seat 71 slidably connected to the lower support 6. The movable seat 71 is slidably connected to the through groove on the lower support 6 via guide rods symmetrically arranged at both ends. A return spring is provided between the movable seat 71 and the lower support 6. A lifting frame 72 is slidably connected to the guide rods at the four corners of the top of the movable seat 71. A lifting cylinder 75 is fixedly connected to the movable seat 71. The output end of the lifting cylinder 75 is fixedly connected to the lifting frame 72, which can drive the lifting frame 72 to move up and down along the guide rods. An arc-shaped alignment component 73 is provided on the top of the lifting frame 72. Alignment blocks are evenly fixedly arranged on the bottom of the cutting table 2. 74. The bottom of the alignment block 74 has a corresponding arc-shaped groove for the alignment piece 73. The spacing of the alignment blocks 74 is consistent with the spacing of the support pieces 5. An eccentric transfer mechanism 8 is provided on the lifting frame 72. A limit plate is fixed on one side of the top of the cutting table 2. The eccentric transfer mechanism 8 can move the remaining scraps to the top of the cutting table 2 near the limit plate after cutting. At the same time, it can prevent the scraps from falling off the cutting from accumulating between the support pieces 5, ensuring the stable operation of the cutting work. When the eccentric transfer mechanism 8 is working, the lifting cylinder 75 drives the lifting frame 72 to move upward. During the upward movement, the alignment is... Block 74 repositions the arc-shaped alignment piece 73 and adjusts the position of the movable seat 71 on the lower support 6 so that the eccentric transfer mechanism 8 can be precisely embedded in the gap between adjacent support pieces 5. The moving module 3 includes a first electric slide rail 31 fixed on one side of the top of the outer support 1. A transverse frame 32 is connected to the slider of the first electric slide rail 31. The transverse frame 32 is slidably connected to the outer support 1. A second electric slide rail 33 is provided on the transverse frame 32. The laser cutting head 4 is fixed on the slider of the second electric slide rail 33. The lower support 6 is fixed to the bottom of the transverse frame 32 and can move synchronously with the transverse frame 32.

[0022] When the device is working, the outer support 1 provides stable support for the overall structure. The cutting table 2 is fixed inside the outer support 1. The support plates 5 evenly arranged on the cutting table 2 provide multi-point support for the angle steel raw material to be cut. The top of the support plate 5 adopts a serrated structure, which reduces the contact area with the angle steel raw material while supporting the angle steel, effectively avoiding the concentrated accumulation of cutting heat on the surface of the angle steel raw material and reducing the impact of thermal deformation on cutting accuracy. The moving module 3 drives the laser cutting head 4 to achieve multi-directional displacement. During the process: the first electric slide rail 31 drives the transverse frame 32 to move laterally along the outer support 1, and the second electric slide rail 33 on the transverse frame 32 drives the laser cutting head 4 to move longitudinally. Through the linkage between the transverse and longitudinal directions, the laser... The cutting head 4 can reach any designated position above the cutting table 2 to perform laser cutting on the angle steel material on the support plate 5. The lower support 6 is fixedly installed at the bottom of the transverse frame 32 and can move laterally synchronously with the transverse frame 32, so that the alignment lifting mechanism 7 and the eccentric transfer mechanism 8 on the lower support 6 always follow the working area of ​​the laser cutting head 4 to achieve follow-up cleaning and transfer. When waste cleaning and transfer of broken plates are required after cutting, the alignment lifting mechanism 7 and the eccentric transfer mechanism 8 work together: the movable seat 71 slides with the through groove on the lower support 6 through the symmetrical guide rods at both ends. The reset spring between the movable seat 71 and the lower support 6 provides the movable seat 71 with initial reset and floating compensation capabilities. The guide rods at the four corners of the top of the movable seat 71 are slidably connected to the lifting frame 72, forming a vertical guide structure. The lifting cylinder 75 on the movable seat 71 is activated, and its output pushes the lifting frame 72 upwards, causing the lifting frame 72 to rise steadily along the guide rods. During the upward movement of the lifting frame 72, the arc-shaped alignment member 73 at the top of the lifting frame 72 gradually approaches and inserts into the slot of the alignment block 74 fixed at the bottom of the cutting table 2. The bottom slot of the alignment block 74 matches the shape of the arc-shaped alignment member 73. Under the guidance of the arc surface, the lateral position of the movable seat 71 on the lower support 6 is automatically corrected and adjusted, achieving precise alignment. The spacing of the alignment blocks 74 is consistent with the spacing of the support plates 5, ensuring that the lifting frame 72 and the eccentric transfer mechanism 8 above it are aligned. It can accurately embed itself in the gap between adjacent support plates 5 to avoid interference with the support plates 5. After alignment, the eccentric transfer mechanism 8 rises to the working height with the lifting frame 72. Through its own rotation or reciprocating eccentric motion, it moves and pushes the cutting scraps that are accidentally piled up between the support plates 5, so that the scraps are released from the gap between the support plates 5 and fall smoothly, preventing the scraps from accumulating and blocking and causing abnormal material discharge, and ensuring that the cutting area is continuously unobstructed. At the same time, the eccentric transfer mechanism 8 pushes up the remaining scraps after cutting and moves them to the top side of the cutting table 2 by pushing and shifting. With the limiting plate, the scraps are neatly transported to the designated area near the limiting plate, which is convenient for picking up the scraps later.

[0023] Please see Figures 2-9The eccentric transfer mechanism 8 includes a mounting frame 81 fixed to the top of the lifting frame 72. Multiple drive shafts 82 are rotatably connected to the mounting frame 81. The drive shafts 82 are connected to the drive mechanism 83, and a transfer cam 84 is fixedly sleeved on each drive shaft 82. The transfer cam 84 is equipped with a shaking mechanism 85 to dislodge residue from the support plate 5 and a cleaning mechanism 86 to clean the surface of the support plate 5. The drive mechanism 83 includes a closed shell 831 fixed to the mounting frame 81. A drive shaft 832 is rotatably connected to the closed shell 831. A drive motor 833 is fixedly mounted on the mounting frame 81. The output end of the drive motor 833 is connected to the drive shaft 832. 2. Fixed connection: A worm gear 834 is provided on the drive shaft 832, and a worm wheel 835 is fixedly sleeved on one end of the transmission shaft 82. The worm wheel 835 is located inside the closed shell 831 and meshes with the worm gear 834. After the alignment block 74 moves up to the bottom of the bottom groove of the arc-shaped alignment piece 73, the transfer cam 84 is fully embedded in the gap between the adjacent support pieces 5. At the same time, when rotating, one end of the transfer cam 84 is higher than the upper surface of the support piece 5, so that the cut fragments can be moved to the position of the limiting plate by rotation. The shaking mechanism 85 includes a mounting groove 851 opened on one side of the transfer cam 84, and a knocking mechanism is slidably connected in the mounting groove 851. A striking platform 852 is slidably fitted onto a support sleeve 855, which is rotatably connected to a drive shaft 82. A guide groove 856 is provided on the side wall of the support sleeve 855, and a limit frame 857 is fixed in the groove on the side wall of the support sleeve 855. The limit frame 857 is fixed to a mounting bracket 81 and can limit the rotation of the support sleeve 855. A guide block 858, fixed to the outer wall of the striking platform 852, is slidably connected in the guide groove 856. The guide groove 856 includes a power storage section 8561, a power release section 8562, and a connecting section 8563. The two ends of the connecting section 8563 are respectively connected to the power storage section 8561 and the power release section 8562. The power storage section 8561 and the power release section 8562 are interconnected. A support guide rod 853 is slidably connected in the evenly spaced slots of the striking platform 852. The support guide rod 853 is fixedly sleeved on the transfer cam 84. The support guide rod 853 can drive the striking platform 852 and the transfer cam 84 to rotate synchronously. A power storage spring 854 is provided between the transfer cam 84 and the striking platform 852. The cleaning mechanism 86 includes a cleaning disk 861 fixed in the grooves on both sides of the transfer cam 84. Cleaning brushes 862 are evenly arranged on the cleaning disk 861. During the rotation of the transfer cam 84, the cleaning brushes 862 can be driven to clean the slag adhering to the side wall of the support plate 5.

[0024] When the lifting frame 72 moves the arc-shaped alignment component 73 to the bottom of the slot of the alignment block 74 and completes precise alignment, the transfer cam 84 is fully embedded between the gaps of the adjacent support plates 5. During the rotation of the transfer cam 84, the highest point of its outer edge can be higher than the upper surface of the support plate 5. Through continuous rotation, it forms a periodic pushing and pulling action, pushing the remaining scraps of the cut plate towards one side of the cutting table 2. Under the limiting cooperation of the limiting plate, the scraps of the cut plate are smoothly transported to the designated collection position for easy picking up later. The transmission shaft 82 is uniformly driven to rotate by the drive mechanism 83, which in turn drives the transfer cam 84 fixed on it to rotate synchronously. When the drive mechanism 83 is working, the drive motor 833 on the mounting frame 81 starts. The output end drives the drive shaft 832 inside the enclosed housing 831 to rotate, and the worm 834 on the drive shaft 832 rotates accordingly. The worm 834 meshes with the worm wheel 835 at the end of the transmission shaft 82. Through the meshing transmission of the worm 834 and the worm wheel 835, the power of the drive motor 833 is transmitted to each transmission shaft 82, realizing the stable rotation of the transmission shaft 82 and the transfer cam 84. The enclosed housing 831 can protect the internal meshing transmission structure and prevent dust and slag from entering and affecting the transmission accuracy. When the shaking mechanism 85 is working, the transfer cam 84 drives the striking table 852 to rotate synchronously through the support guide rod 853. The striking table 852 is slidably sleeved on the support sleeve 855, and the support sleeve 855 is fixed by the limit frame 857. The guide block 858, positioned at a fixed point, cannot rotate with the drive shaft 82 and the transfer cam 84, maintaining only a fixed posture. The guide block 858 on the outer wall of the striking platform 852 slides along the guide groove 856 on the support sleeve 855. The guide groove 856 is divided into a power storage section 8561, a power release section 8562, and a connecting section 8563. During rotation, the guide block 858 sequentially passes through the power storage section 8561, the connecting section 8563, and the power release section 8562. Within the power storage section 8561, the guide block 858 moves along the groove's trajectory, pushing the striking platform 852 along the support guide rod 853 to compress the power storage spring 854, achieving elastic power storage. When the guide block 858 enters the power release section 8562, the power storage spring 854 rapidly releases its elastic potential energy, pushing the striking platform 852... 52 is quickly ejected along the support guide rod 853, forming a periodic tapping and vibration on one side of the support plate 5, causing the corner scrap and cutting slag stuck in the gap of the support plate 5 to loosen and fall off, avoiding the accumulation and blockage of scrap, and ensuring smooth material discharge. The cleaning mechanism 86 rotates synchronously with the transfer cam 84. The cleaning disk 861 fixed in the groove on both sides of the transfer cam 84 drives the cleaning brush 862 to rotate continuously. The cleaning brush 862 contacts the side wall and gap surface of the support plate 5, and cleans and peels off the high-temperature slag and metal debris attached to the support plate 5 during the rotation, removing the residue from the surface of the support plate 5, further ensuring the cleanliness of the surface of the support plate 5 and the unobstructed gap, and avoiding the adhesion of slag to affect the subsequent angle steel support and cutting accuracy.

[0025] It should be noted that, in use, this laser cutting device for angle steel processing firstly provides stable support for the overall structure of the device through an outer support 1. The cutting table 2 is fixed inside the outer support 1, serving as the working platform for cutting angle steel. Support plates 5, evenly arranged on the cutting table 2, provide multi-point support for the angle steel raw material to be cut. The top of the support plates 5 adopts a serrated structure, which, while stabilizing the angle steel, effectively reduces the contact area with the angle steel raw material, thereby preventing the concentrated accumulation of cutting heat on the surface of the angle steel raw material and reducing the impact of thermal deformation on cutting accuracy. This lays the foundation for subsequent precise cutting. The moving module 3 is then activated, driving the laser cutting... The cutting head 4 achieves multi-directional displacement in both the horizontal and vertical directions to meet the cutting needs of different positions. The specific process is as follows: the first electric slide rail 31, which is fixed on one side of the top of the outer support 1, is activated, and its slider drives the horizontal moving frame 32 to move horizontally along the outer support 1; the second electric slide rail 33 set on the horizontal moving frame 32 moves synchronously, driving the laser cutting head 4, which is fixed on its slider, to move vertically. Through the horizontal and vertical linkage between the first electric slide rail 31 and the second electric slide rail 33, the laser cutting head 4 can be flexibly moved to any designated position above the cutting table 2 to perform precise laser cutting on the angle steel material placed on the support plate 5. The lower support 6 is fixedly installed at the bottom of the transverse frame 32 and can move laterally synchronously with the transverse frame 32. This drives the alignment lifting mechanism 7 and the eccentric transfer mechanism 8 on the lower support 6 to always follow the working area of ​​the laser cutting head 4, realizing follow-up cleaning and transfer operations. This avoids the accumulation of waste material after cutting, which affects subsequent cutting work. After the laser cutting head 4 completes the angle steel cutting operation in the designated area, the alignment lifting mechanism 7 and the eccentric transfer mechanism 8 start working together to perform waste material cleaning and fragmented plate transfer operations. The specific operation process of the alignment lifting mechanism 7 is as follows: the movable seat 71 slides with the through groove on the lower support 6 through the guide rods symmetrically arranged at both ends. The reset spring set between the movable seat 71 and the lower support 6 provides the movable seat 71 with initial reset and floating compensation capabilities, ensuring the flexible movement of the movable seat 71. The guide rods set at the four corners of the top of the movable seat 71 are connected to the lifting frame. 72 is slidably connected to form a stable vertical guide structure; the lifting cylinder 75 fixedly connected to the movable seat 71 is activated, and its output end pushes the lifting frame 72 upward, so that the lifting frame 72 is steadily lifted upward along the guide rod. During the upward movement of the lifting frame 72, the arc-shaped alignment piece 73 set at its top gradually approaches and inserts into the slot of the alignment block 74 evenly fixed at the bottom of the cutting table 2. Since the bottom slot of the alignment block 74 is compatible with the shape of the arc-shaped alignment piece 73, under the guidance of the arc surface, the lateral position of the movable seat 71 on the lower support 6 can be automatically corrected and adjusted to achieve the precise alignment of the eccentric transfer mechanism 8. At the same time, since the arrangement spacing of the alignment block 74 is consistent with the spacing of the support piece 5, it can ensure that the lifting frame 72 and the eccentric transfer mechanism 8 above can be accurately embedded in the gap between the adjacent support pieces 5, avoiding interference with the support pieces 5 and ensuring the normal operation of the eccentric transfer mechanism 8. When the lifting frame 72 moves the arc-shaped alignment component 73 to the bottom of the slot of the alignment block 74 and completes precise alignment, the eccentric transfer mechanism 8 rises with the lifting frame 72 to the working height. During the rotation of the transfer cam 84, the highest point of its outer edge can be higher than the upper surface of the support plate 5. Through continuous rotation, a periodic pushing and pulling action is formed, pushing the remaining scraps of the cut plate towards the top side of the cutting table 2. Under the limiting cooperation of the limiting plate fixed on the top side of the cutting table 2, the scraps of the cut plate are smoothly transported to the designated collection position near the limiting plate, which is convenient for manual picking later. There is no need for manual sorting and transfer of the scraps of the cut plate one by one. The transfer cam 84 rotates to perform the transfer of the scraps of the cut plate. Simultaneously with the operation, the shaking mechanism 85 and the cleaning mechanism 86 installed on it move synchronously to complete the cleaning of waste and slag from the gap and surface of the support plate 5. The specific working process of the shaking mechanism 85 is as follows: the transfer cam 84 drives the tapping table 852 and the transfer cam 84 to rotate synchronously through the support guide rod 853 slidably connected in the through slot evenly opened on the tapping table 852 in the mounting groove 851 on one side; the tapping table 852 is slidably sleeved on the support sleeve 855, and the limiting frame 857 restricts the rotation of the support sleeve 855, so that the support sleeve 855 always maintains a fixed posture. The guide block 858 fixed on the outer wall of the tapping table 852 moves along the side wall of the support sleeve 855. The guide groove 856 slides, and during rotation, the guide block 858 passes sequentially through the energy storage section 8561, the connecting section 8563, and the energy release section 8562. In the energy storage section 8561, the guide block 858 moves along the groove's trajectory, pushing the striking platform 852 along the support guide rod 853 to compress the transfer cam 84 and the energy storage spring 854 located between the striking platform 852, achieving elastic energy storage. When the guide block 858 enters the energy release section 8562, the energy storage spring 854 rapidly releases its elastic potential energy, pushing the striking platform 852 to rapidly eject along the support guide rod 853, forming periodic striking and vibration on one side of the support plate 5, causing the corner scrap and cut material stuck in the gap of the support plate 5 to... The molten slag loosens and falls off, preventing waste accumulation and blockage, and ensuring smooth material discharge. The cleaning disk 861 of the cleaning mechanism 86 is fixed in the grooves on both sides of the transfer cam 84. Cleaning brushes 862 are evenly arranged on the cleaning disk 861. When the transfer cam 84 rotates synchronously, it drives the cleaning disk 861 and cleaning brushes 862 to rotate continuously. The cleaning brushes 862 make full contact with the side wall and gap surface of the support plate 5. During the rotation, the high-temperature molten slag and metal debris attached to the support plate 5 are thoroughly cleaned and peeled off, and the residue is completely removed from the surface of the support plate 5. This further ensures that the surface of the support plate 5 is clean and the gap is unobstructed, and avoids molten slag adhesion from affecting the support stability and cutting accuracy of the subsequent angle steel.

[0026] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
