Description

Technical Field

[0001] The invention relates to the field of laser cutting, and in particular to laser cutting equipment and a cutting process for processing steel plates for cranes. Background Art

[0002] High precision and high efficiency: Laser cutting technology has significant precision advantages in steel plate cutting, with narrow incision width, small hole center distance error and profile size error. In addition, laser cutting is also fast and can quickly complete complex cutting tasks. Laser cutting can handle steel plates of various shapes and sizes, no matter how complex they are, it can easily cope with them. This makes it very flexible and applicable in industrial production. The cut surface produced by laser cutting is flat and smooth, without burrs and slag, and will not scratch the surface of the workpiece, eliminating the need for secondary grinding. This high-quality cutting effect is very important for subsequent processing and use. Although the investment in laser cutting equipment is high, its relatively low operating cost and efficient cutting speed make it highly cost-effective in long-term use. Water jet cutting is an environmentally friendly and safe cutting method that uses high-pressure water flow to locally cut the steel plate into the desired shape, and is suitable for steel plates of various thicknesses. This method is not only environmentally friendly, but also safe to operate and reduces occupational health risks. Modern steel plate cutting production lines are usually equipped with intelligent cranes for automated loading and unloading and storage, which improves overall production efficiency and accuracy. For example, in a factory's intelligent plate cutting line, the intelligent crane automatically places the steel plate on the cutting platform and removes it after cutting, greatly simplifying the operation process and improving work efficiency. The benefits of crane steel plate cutting include high precision, high efficiency, versatility, high-quality cutting effects, cost-effectiveness, environmental protection and safety, as well as automation and intelligence. These advantages make laser cutting an indispensable and important technical means in modern industrial production. The existing laser cutting equipment and cutting process for crane steel plate processing cannot clean up harmful gases well after dust removal, which may affect the health of workshop workers.

[0013] The present invention provides a laser cutting device and cutting process for processing steel plates for cranes. It has the following beneficial effects: 1) The laser cutting equipment and cutting process for processing steel plates for cranes are provided with a clamping device and a two-dimensional moving device. The staff first slides the cooling device to the far left through the wheels to facilitate loading and unloading, and then places the steel plate for cranes on the surface of the placement plate, and then starts the second cylinder. The piston rods of the two second cylinders move relative to each other, driving the clamping plates at the tops of the two cylinders to approach each other, and clamping the steel plate for cranes. Then, the first motor is started, and the rotation of the first motor drives the rotation of the first screw rod, and the rotation of the first screw rod drives the base on its outer surface to slide the thread, so that the base drives the cutting device at its bottom to reciprocate left and right. At the same time, the staff can start the first cylinder, and the piston rod of the first cylinder drives the cutting device at its bottom to move up and down. In this way, the effect of two-dimensional driving of the cutting device is achieved; 2) The laser cutting equipment and cutting process for processing the steel plate for the crane are as follows: by setting up a cutting device, laser generators of different powers are selected according to the thickness of the steel plate for the crane. If the steel plate for the crane is relatively thin, a low-power laser drill located at the bottom of the flip plate can be directly used; if the steel plate for the crane is relatively thick, the second motor is started, and the second motor drives the second screw rod to rotate, thereby driving the flip plate on the outer surface of the second screw rod to reverse, and the high-power laser drill bit on the top of the flip plate is positioned downward to cut the steel plate.

[0014] 3) The laser cutting equipment and cutting process for processing the steel plate for the crane are equipped with a cooling device. After the cutting is completed, the staff adds clean water to the water tank, and then starts the water pump assembly. The water pump assembly works to pump clean water into the spray pipe and spray it out through the pumping pipe. In this process, the temperature sensor detects the temperature of the workbench surface in real time through the wire, so as to judge the degree of cooling. When the temperature drops to the appropriate temperature, the water pump assembly is turned off, and the staff takes out the steel plate for the crane to complete the cutting. Dust and exhaust gas will be generated during the cutting process. 4) The laser cutting equipment and cutting process for processing steel plates for the crane, by setting up an exhaust gas treatment mechanism and a dust suction mechanism, will generate dust and exhaust gas during the cutting process. For dust, the dust on the workbench can be sucked into the partition box by starting the suction fan to suck air from the workbench, and the dust enters the dust collection box through the dust collection pipe for collection. When the dust collection box needs to be cleaned, the rotating block drives the threaded column to rotate, and the extrusion plates on the threaded column move in opposite directions to release the dust collection box for cleaning. The staff can drive the threaded rod to rotate by turning the driving handle. At this time, the two driving sliders on the threaded rod move relative to each other and use the linkage rod to push the mounting plate downward, so that the suction fan is more in line with the workbench, thereby increasing the dust removal efficiency. For exhaust gas, the staff starts the air pump, and the air pump works to transport the exhaust gas into the exhaust gas treatment chamber through the air inlet hopper and the air pipe. After the exhaust gas enters the exhaust gas treatment chamber, it enters the dust removal bag, and then starts the heating rod, the heating rod heats the air, and blows it upward through the heating fan, heats the flue gas treatment chamber through the heating hole, heats the toxic gas into harmless gas, and then discharges it through the exhaust pipe.

[0028] When in use, the staff first slides the cooling device 17 to the far left through the wheel 171 to facilitate loading and unloading, and then places the steel plate for the crane on the surface of the placement plate 4, and then starts the second cylinder 51. The piston rods of the two second cylinders 51 move relative to each other, driving the clamping plates 52 at the top ends to approach each other, and clamping the steel plate for the crane. Then, the first motor 92 is started, and the rotation of the first motor 92 drives the first screw rod 91 to rotate. The rotation of the first screw rod 91 drives the base 93 on its outer surface to slide in a thread, so that the base 93 drives the cutting device 10 at its bottom to reciprocate left and right. At the same time, the staff can start the first cylinder 94. The first cylinder 94 The piston rod drives the cutting device 10 at its bottom to do lifting movement. In this way, the effect of two-dimensional driving of the cutting device 10 is achieved; then, according to the thickness of the crane steel plate, laser generators of different powers are selected. If the crane steel plate is relatively thin, the low-power laser drill 106 located at the bottom of the flip plate 104 can be directly used. If the crane steel plate is relatively thick, the second motor 103 is started, and the second motor 103 drives the second screw rod 102 to rotate, thereby driving the flip plate 104 on the outer surface of the second screw rod 102 to reverse, and the high-power laser drill 105 on the top of the flip plate 104 is positioned downward, thereby cutting the steel plate. After the cutting is completed, the staff adds clean water into the water tank 172, and then starts the water pump assembly 173. The water pump assembly 173 works to draw clean water into the spray pipe through the suction pipe and spray it out. In this process, the temperature sensor 177 detects the temperature of the surface of the workbench 1 in real time through the wire 178, so as to judge the degree of cooling. When the temperature drops to a suitable temperature, the water pump assembly 173 is turned off, and the staff takes out the steel plate for the crane to complete the cutting. Dust and exhaust gas will be generated during the cutting process. For dust, the suction fan 122 can be started to suck air from the workbench 1 to suck the dust on the workbench 1 into the partition box 123, and the dust enters the dust box 126 through the dust collecting pipe 125 for collection. When the dust box 126 needs to be cleaned, the rotating block 120 is rotated to drive the threaded column 129 to rotate, and the extrusion plates 127 on the threaded column 129 move in opposite directions to release the dust box 126 for cleaning. The staff can drive the threaded rod 113 to rotate by rotating the driving handle 112. At this time, the two driving sliders 114 on the threaded rod 113 move relative to each other and use the linkage rod 116 to push the mounting plate 115 downward, so that the suction fan 122 is more closely attached to the workbench 1, thereby increasing the dust removal efficiency. For waste gas, the staff starts the air pump 145, and the air pump 145 works to transport the waste gas into the flue gas treatment chamber 141 through the air inlet hopper 149 and the air pipe 148.
