[0016] Specifically, Figures 1 to 15 As shown, a semi-automatic loading and unloading high-performance laser cutting machine includes a loading station, a cutting processing station and a unloading station arranged in sequence along the horizontal direction; The cutting processing station is provided with a cutting mechanism 1, which includes a cutting frame 11, an X-axis sliding assembly 12 installed at the front and rear ends of the top of the cutting frame 11, a Y-axis sliding assembly 13 installed on the X-axis sliding assembly 12, a Z-axis sliding assembly 14 installed on one side of the Y-axis sliding assembly 13, a cutting head 15 installed on one side of the bottom of the Z-axis sliding assembly 14, and a material unloading flap 16 installed at the bottom of the cutting frame 11; The loading station is provided with a loading and conveying unit 2, a clamping and feeding device 3 installed on one side of the loading and conveying unit 2, a loading bracket 4 arranged on the other side of the loading and conveying unit 2, and a loading flat car 5 installed on the ground rail; The unloading station is provided with a power conveying unit 6, a short material pneumatic bracket 7 at one end of the power conveying unit 6, an unloading bracket 8 arranged at one side of the power conveying unit 6, and an unloading flat car 9 installed on the slide rail.

[0017] It should be noted that this design raises the main frame of the equipment by 1.2 meters, thereby reducing the height of the beam from 1.8 meters to 0.6 meters, and the weight of the beam from 1200Kg to 500Kg, so that under the same motor power drive, the acceleration of the beam operation increases from 0.3G to 0.8G, and the operating speed increases from 30m / min to 60m / min; In addition, the cutting processing station is a fixed area, so the present design uses a pneumatic unloading flap 16 to concentrate the cutting waste on the ground slope, and then the ground slope collects the waste into the waste hopper outside the cutting area to facilitate the centralized treatment of the waste later.

[0018] In actual work, the entire cutting area can be covered with sheet metal and graphite plates can be installed inside the sheet metal for protection, which can protect people from external laser damage to the greatest extent. A dust removal device can also be set up to centrally handle the waste gas and dust generated during the cutting process.

[0019] In detail, the present solution can be used to transport the steel section to the loading and conveying unit 2 through the loading flat car 5, and then the steel section wing plate is clamped by the clamping and feeding device 3 to push the material, and the steel section is pushed to the cutting area; the cutting area is provided with a 1.2-meter steel section cutting space, and when the processing of the 1.2-meter area is completed, the loading device will continue to transport, and the servo motor is used for the pushing movement, so the accuracy can meet the requirements.

[0021] It should be noted that when the position of the cutting head 15 on the X-axis needs to be adjusted, it is only necessary to start the X-axis drive motor 123 to drive the X-axis drive gear 124 connected to its output shaft to rotate, and through the cooperation with the X-axis drive rack 125, the base 122 is driven to slide on the X-axis slide rail 121, thereby adjusting the X-axis position of the cutting head 15.

[0022] The Y-axis sliding assembly 13 includes a crossbeam 131 installed on the base 122, a Y-axis slide rail 132 installed on the crossbeam 131, a support seat 133 slidably set on the Y-axis slide rail 132, a Y-axis drive motor 134 installed on the support seat 133, a Y-axis drive gear 135 connected to the output shaft of the Y-axis drive motor 134, a Y-axis drive rack 136 installed on the Y-axis slide rail 132 and adapted to the Y-axis drive gear 135, and a Y-axis limit collision block 137 installed on both sides of the Y-axis slide rail 132.

[0023] It should be noted that when the position of the cutting head 15 on the Y-axis needs to be adjusted, it is only necessary to start the Y-axis drive motor 134 to drive the Y-axis drive gear 135 connected to its output shaft to rotate, and through the cooperation with the Y-axis drive rack 136, drive the support seat 133 to slide on the Y-axis slide rail 132, thereby adjusting the Y-axis position of the cutting head 15.

[0025] It should be noted that when the position of the cutting head 15 on the Z-axis needs to be adjusted, it is only necessary to start the Z-axis drive motor 143, which can drive the Z-axis drive gear 144 connected to its output shaft to rotate, and drive the Z-axis slide 141 to slide on the Z-axis slide rail 142 through cooperation with the Z-axis drive rack 145, thereby adjusting the Z-axis position of the cutting head 15.

[0026] The clamping and feeding device 3 includes a side support frame 31, and a mounting seat 33 is slidably connected to the side support frame 31 through a sliding component 32. A slide plate 34 is slidably connected to one side of the mounting seat 33. A reduction motor 35 for driving the slide plate 34 to move is installed on the top of the mounting seat 33. A push rod 36 is hinged on the driving slide plate 34, and a material supporting clamp 37 is hinged at the front end of the push rod 36.

[0027] It should be noted that the material-supporting clamping jaws 37 are driven by a hydraulic cylinder to clamp the steel section, and then the clamped steel section is pushed forward by the sliding assembly 32 , while the reduction motor 35 is used to adjust the height of the material-supporting clamping jaws 37 .

[0028] The sliding assembly 32 includes a transverse sliding rail 321 , a servo motor 322 mounted on a mounting seat 33 , a felt gear 323 connected to an output shaft of the servo motor 322 , and a helical rack 324 mounted on the side support frame 31 .

[0029] It should be noted that when the steel section needs to be pushed forward, it is only necessary to start the servo motor 322 to drive the felt gear 323 to rotate, and drive the mounting seat 33 to move to the front side through cooperation with the bevel rack 324, thereby completing the work of pushing the steel section forward.

[0030] The power transmission unit 6 is provided with a steel clamping mechanism 10 and a positioning roller 11 .

[0031] It should be noted that the conveying roller in the unloading area is powered, namely the power transmission unit 6, so when the cut workpiece is pushed to the unloading roller, it will be transported to the corresponding unloading area and transported to the finished product support frame by the unloading trolley. The extremely short small materials will be pushed to the very end and fall into the small material collection box.

[0032] In addition, the steel section clamping mechanism 10 is used to accurately clamp the steel section to the positioning roller, which is convenient for subsequent work.

[0033] The specific working method is described below with specific embodiments: Example 1

[0034] The steel section is transported to the loading and conveying unit 2 through the loading flat car 5, and then the steel section wing plate is clamped by the clamping and feeding device 3 to push the material, and the steel section is pushed to the cutting area, thereby completing the cutting of the steel section. When the cut workpiece is pushed to the power transmission unit 6, it will be transported to the corresponding unloading area and transported to the finished product support frame by the unloading flat car 9. The extremely short small materials will be pushed to the end and fall into the small material collection frame. Example 2

[0035] During cutting, the position of the cutting head 15 needs to be adjusted in real time. At this time, the spatial position of the cutting head 15 can be adjusted by the X-axis sliding assembly 12, the Y-axis sliding assembly 13 and the Z-axis sliding assembly 14 as needed. Example 3

[0036] When the length of the raw material is 15 meters, and the cut workpieces are long and short, we only need to nest the graphics in the nesting software. When cutting, we first clamp and feed 1.2 meters of length into the cutting area. The equipment first cuts the end flush, and the cut waste will fall onto the slope and be collected in the waste material cart. After the end is cut flat, it will be processed into the required shape. After the first section is cut off, the cut workpiece will be transported to the corresponding unloading end by the unloading roller. The equipment continues to process the second workpiece. When the length of the second workpiece exceeds 1.2 meters, it is necessary to continue to clamp and feed. When processing the last workpiece, the clamping and feeding will deliver all the steel sections. After processing, the workpieces are all transported to the unloading end, and the loading end continues to load and process.

[0037] In addition, the equipment can also be used with steel section welding lines to complete the factory's output from plate raw materials to H-shaped steel workpieces.

[0038] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above-mentioned concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
