Description

Technical Field

[0001] The utility model relates to cutting equipment, in particular to a laser cutting machine. Background Art

[0002] Laser cutting machines, a vital piece of equipment in modern industrial manufacturing, operate based on the high-energy properties of laser beams. When the laser beam precisely strikes the workpiece surface, its powerful energy rapidly causes a localized area of the workpiece to reach its melting or boiling point. Simultaneously, a jet of high-pressure gas, coaxial with the laser beam, rapidly blows the molten or vaporized metal away from the cutting area, achieving precise cutting and processing of the workpiece.

[0003] In traditional laser cutting production lines, there is often a problem of insufficient coordination between the feeding mechanism and the feed mechanism. Specifically, in the traditional process, the feeding mechanism usually starts to feed the new profile onto the material roller only after the feed mechanism completes a cut and returns to the starting position. The next cutting preparation can only be started after the feed mechanism is in place again. This increases the waiting time in the overall processing cycle, resulting in significantly lower production efficiency.

[0004] Furthermore, when processing longer profiles, traditional laser cutting machines typically incorporate a separate clamping mechanism on the outside of the cutting mechanism to secure one end of the profile, ensuring stability during the cutting process and preventing machining errors caused by vibration. This independent clamping mechanism increases the number of components and complexity of the equipment, raising manufacturing costs and making maintenance more difficult. Utility Model Content

[0005] The purpose of this utility model is to provide a laser cutting machine to solve the problems of low production efficiency caused by the lack of coordination between the feeding mechanism and the feeding mechanism of the traditional laser cutting machine, and the increase in the number of parts and complexity of the equipment caused by setting an independent clamping mechanism on the outside of the cutting mechanism.

DETAILED DESCRIPTION

[0025] like Figure 1 As shown, the utility model includes a loading device 1 and a feeding and cutting device 2.

[0026] The loading device 1 includes a loading frame 11, a coiling mechanism 12 mounted on the loading frame 11, a conveying mechanism 13, and a feeding mechanism 14. The loading device 1 is used to transport profiles to the feeding and cutting device 2. The coiling mechanism 12 is used to store the profiles and lift them to the conveying mechanism 13. The conveying mechanism 13 is used to transport the profiles from the coiling mechanism 12 to the feeding mechanism 14. The profiles are transported from the rear of the conveying mechanism 13 to the front of the conveying mechanism 13. The feeding mechanism 14 is used to transport the profiles from the conveying mechanism 13 to the feeding and cutting device 2.

[0027] The winding mechanism 12 includes a winding belt 121, a roller 122, a winding drum 123, and a winding drive shaft 124. The winding belt 121, roller 122, and winding drive shaft 124 are connected to the loading frame 11, and the winding drum 123 is fixed to the winding drive shaft 124. One end of the winding belt 121 is connected to the loading frame 11, and the other end is connected to the winding drum 123. The winding drive shaft 124 drives the winding drum 123 to rotate, realizing the retraction and expansion of the winding belt 121. The winding belt 121, roller 122, and winding drum 123 are each provided in multiple groups. The winding belts 121 are arranged parallel to each other, and the winding drums 123 are each mounted on the winding drive shaft 124. The winding drums 123 are driven by the winding drive shaft 124 to achieve synchronous movement of the winding belts 121, and together they lift the profile onto the conveyor mechanism 13.

[0028] A limit rod 125 is provided on the loading rack 11. The gap between the limit rod 125 and the roller 122 is slightly larger than the size of the profile to ensure that only one profile can pass through at a time, preventing two or more profiles from entering the conveyor mechanism 13 simultaneously. The coil drive shaft 124 is driven by a coil motor 126. In this embodiment, the coil motor 126 and the coil drive shaft 124 are connected by a coil sprocket 127 provided on both the output shaft of the coil motor 126 and the coil drive shaft 124, with a coil chain 128 provided between the coil sprockets 127. The coil motor 126 can also be connected to the coil drive shaft 124 via a coupling or gears.

[0029] The conveying mechanism 13 includes a conveyor sprocket 131, a conveyor chain 132, a conveyor drive sprocket 133, and a conveyor drive shaft 134. The conveyor sprocket 131 and conveyor drive shaft 134 are connected to the loading rack 11. The conveyor drive sprocket 133 is fixed to the conveyor drive shaft 134 and connected to the conveyor chain 132. The conveyor drive shaft 134 drives the conveyor chain 132 through the conveyor drive sprocket 133, thereby moving the profile. There are several groups of conveyor sprockets 131, conveyor chains 132, and conveyor drive sprockets 133. Each group of conveyor sprockets 131 is arranged parallel to the conveyor chains 132. Each group has two conveyor sprockets 131, one in front and one behind, located at the front and rear of the loading rack 11 to maintain the conveyor chains 132 horizontally. The conveyor drive sprockets 133 are all mounted on the conveyor drive shaft 134. The conveyor drive shaft 134 drives the conveyor chain 132 to rotate through the conveyor drive sprocket 133, thereby moving the profile forward. The conveying transmission shaft 134 is driven by a conveying motor 135. In this embodiment, the conveying motor 135 drives the conveying transmission shaft 134 through a sprocket and a chain. The conveying motor 135 can also be connected to the conveying transmission shaft 134 through a coupling or a gear.

[0030] The feeding mechanism 14 includes a feeding telescopic driving element 141 arranged on the loading rack 11, a lifting telescopic driving element 142 arranged on the feeding telescopic driving element 141, and a lifting plate 143 arranged on the lifting telescopic driving element 142. The feeding mechanism 14 is used to transport the profile on the conveying mechanism 13 to the feeding and cutting device 2. Specifically, the lifting telescopic driving element 142 is used to lift the profile from the conveying mechanism 13, and the feeding telescopic driving element 141 is used to send the lifted profile to the feeding and cutting device 2.

[0031] like Figure 2As shown, the feeding and cutting device 2 includes a feeding frame 21, a receiving and supporting integrated mechanism 22 arranged on the feeding frame, a feeding mechanism 23, a clamping mechanism 24, and a cutting mechanism 25. The feeding frame 21 is stepped, and the feeding frame 21 has two steps. The receiving and supporting integrated mechanism 22 is arranged on the lower step, and the feeding mechanism 23, the clamping mechanism 24, and the cutting mechanism 25 are arranged on the higher step. The lower step is close to the feeding mechanism.

[0032] A guard plate is provided on the surface of the feed rack 21, and the pipe harness is placed inside the guard plate. The guard plate protects the precision components of the equipment from being damaged by external factors, thereby extending the service life of the equipment. Figure 2 The feed frame 21 in the embodiment has a guard plate. Figure 3 and Figure 4 The middle part is the appearance of removing the feed frame 21 guard plate.

[0033] The receiving and supporting mechanism 22 receives the profile delivered by the feeding mechanism 14 and supports it at the bottom of the profile while the feeding mechanism 23 moves the profile to the cutting mechanism 25. The feeding mechanism 23 clamps the left end of the profile and moves the profile to the cutting mechanism 25. The clamping mechanism 24 holds the profile section near the cutting mechanism 25 to maintain its stability during cutting. The cutting mechanism 25 is used to cut the profile.

[0034] like Figure 5 As shown, the integrated receiving and supporting mechanism 22 includes a supporting and retractable drive element 221 connected to the feed frame 21, a supporting roller 222 connected to the supporting and retractable drive element 221, a receiving and retractable drive element 223, and a receiving plate 224 and a centering mechanism connected to the receiving and retractable drive element 223. The receiving and retractable drive element 223 is used to lift the receiving plate 224 to receive the profile delivered by the feeding mechanism 14 and place the profile on the supporting roller 222. The centering mechanism is used to center and position the profile to facilitate feeding, clamping, and cutting. The supporting and retractable drive element 221 is used to lift the supporting roller 222 and the profile thereon so that the feeding mechanism 23 can push the profile to the cutting mechanism 25 for processing. The centering mechanism includes a centering and retractable drive element 225 provided on the receiving and retractable drive element 223 and a centering roller 226 provided on the receiving and retractable drive element 224. The telescopic drive elements in the integrated support mechanism 22 are all cylinders, among which the centering telescopic drive element 225 is a double-acting cylinder, the piston rods at both ends of which can be extended or retracted at the same time, and centering rollers 226 are connected to the piston rods. When the piston rods are retracted, the two centering rollers clamp the profile so that the center of the profile and the center of the clamping mechanism 24 are on the same axis, which is convenient for the clamping and positioning of the clamping mechanism 24.

[0035] The feed mechanism 23 includes a first guide rail 231 mounted on the feed frame 21, a first carriage 232 mounted on the first guide rail 231, and a rotary clamping mechanism 233 mounted on the first carriage 232. The feed frame 21 is also provided with a rack 234 parallel to the first guide rail 231. The first carriage 232 is equipped with a motor, and a gear (not shown) is mounted on the motor's output shaft to mate with the rack. The motor, gear, and rack enable the feed mechanism to move left and right on the frame. The rotary clamping mechanism 233 is used to clamp the left end of the profile and rotate it to facilitate the cutting mechanism 25's processing. The first guide rail 231 is mounted on the upper step, and the rear end of the first carriage 232 extends horizontally above the lower step. The rotary clamping mechanism 233 is located above the lower step.

[0036] like Figure 3 and Figure 4 As shown, the clamping mechanism 24 includes a second slide rail 241 and a positioning and telescopic driving element 242 arranged on the feed frame 21, a second sliding frame 243 arranged on the second guide rail, and a chuck 244 arranged on the second sliding frame 243. The piston rod of the positioning and telescopic driving element 242 is connected to the second sliding frame 243, and the positioning and telescopic driving element 242 is used to adjust the position of the chuck 244.

[0037] During the process of the feeding mechanism 23 moving the profile to the cutting mechanism 25, the supporting and retracting drive element 221 of the receiving and supporting integrated mechanism 22 is in an extended state. At this time, the rotating clamping mechanism 233, the receiving and supporting integrated mechanism 22, and the clamping mechanism 24 are in a straight line. In the initial state or during the process of the feeding mechanism 23 returning from the right part to the left part of the feed frame 21 after the cutting of a profile is completed, the supporting and retracting drive element 221 of the receiving and supporting integrated mechanism 22 is in a retracted state. The upper end of the receiving and supporting integrated mechanism 22 is lower than the lower end of the feeding mechanism 23. There is room for the feeding mechanism 14 to feed the profile to the receiving and supporting integrated mechanism 22 between the receiving and supporting integrated mechanisms 22 and the feeding mechanism 23. In this way, when the feeding mechanism 14 moves the profile to the receiving and supporting integrated mechanism 22, it will not interfere with the feeding mechanism 23 moving to the left. Before the feed mechanism 23 moves to the left end of the feed frame 21, the feeding mechanism 14 completes feeding, and the centering telescopic drive element 225 of the receiving and supporting integrated mechanism 22 completes the centering of the profile. When the feed mechanism 23 moves to the left end of the feed frame 21, the telescopic drive element 221 of the receiving and supporting integrated mechanism 22 is extended to lift the profile, and the clamping mechanism 23 is rotated to clamp the left end of the profile to begin feeding the cutting mechanism 25. This avoids the waiting time during the previous process of the feed mechanism 23 moving to the left end before the feed mechanism 14 begins to move the profile to the receiving and supporting integrated mechanism 22, saving processing time and improving work efficiency.

[0038] The cutting mechanism 25 is arranged near the right end of the feed frame 21, and includes a cutting frame 251 arranged on the feed frame 21 and a laser generator 252 arranged on the cutting frame 251. The laser generator 252 is arranged on the cutting frame 251 through a cross slide 253. Through the cross slide 253, the laser generator 252 can move up and down and forward and backward.

[0039] The clamping mechanism 24 is positioned near the cutting mechanism 25. Its adjustable and retractable drive element 242 can move the chuck 244 to the left or right of the laser generator 252 to accommodate the clamping needs of profiles of varying sizes. Specifically, in the initial state, the adjustable and retractable drive element 242 is retracted, and the chuck 244 is positioned to the left of the laser generator 252. When the feed distance of the feed mechanism 23 is short, and the length of the profile extending from the chuck 244 is short, the profile section to the left of the chuck 244 remains stable, and the chuck 244 remains to the left of the laser generator 252. When the feed mechanism 23 feeds a long distance and the profile extends a long distance from the chuck 244, the section of profile to the left of the chuck 244 will vibrate, affecting the machine's processing accuracy. In this case, the retractable drive element 242 is extended to move the chuck 244 to the right of the laser generator 252. The rotating clamping mechanism 233 and chuck 244 then jointly clamp the profile, maintaining a stable state during processing. The retractable drive element 242 eliminates the need for a separate clamping mechanism to the right of the cutting mechanism 25, reducing the number of components, complexity, and cost of the machine.

[0040] The present invention further includes a blanking device 3, which includes a blanking trough 31 and a blanking plate 32 disposed on the blanking trough 31. The blanking plate 32 is disposed obliquely, and the material cut by the cutting mechanism 25 falls on the blanking plate 32 and then falls along the blanking plate 32 into the blanking trough 31. The blanking device 3 is used to collect the material cut by the cutting mechanism 25.
