Description

Technical Field

[0001] This invention relates to the field of sheet metal processing equipment, and more specifically, to a composite processing device for ultra-large and ultra-thick sheets based on laser plasma flame. Background Technology

[0002] Regarding flame cutting of ultra-large and ultra-thick plates, oxypropane flames are currently the main method used both domestically and internationally. This is primarily because oxypropane flames offer suitable temperatures, good combustion stability, are less prone to backfire, have a longer flame length than typical gaseous fuel flames, can heat thicker metals, and have relatively low cutting costs. Metal thermal cutting can be categorized into flame cutting, plasma arc cutting, and laser cutting. Flame cutting is a type of metal oxidation cutting, where a flame preheats the metal to its ignition point, then pure oxygen is introduced to oxidize it into a low-melting-point molten slag, releasing a large amount of heat to further heat the metal being cut. Currently, the maximum thickness that can be achieved with conventional flame cutting is 1800mm. Laser plasma arc cutting utilizes a high-temperature plasma arc to heat and melt the metal, then blows it open to form a kerf; this is a type of melting cutting.

[0003] However, existing ultra-large and ultra-thick plates are inconvenient to move and cut during the cutting process, which reduces the efficiency of cutting ultra-large and ultra-thick plates. In addition, fine and harmful fumes are easily generated during the cutting process, which is harmful to the health of workers and the entire working environment. Therefore, we propose a composite processing device for ultra-large and ultra-thick plates based on laser plasma flame to solve the above-mentioned problems. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a composite processing device for ultra-large and ultra-thick plates based on laser plasma flame. This device can not only facilitate the processing and cutting of ultra-large and ultra-thick plates of different models, but also purify the fumes generated during the processing and cutting process, thereby reducing the pollution of fumes to workers' health and the entire working environment.

[0011] A laser plasma flame generator is disposed above one side of the base, and the output end of the laser plasma flame generator is conductively connected to the input end of the laser plasma flame gun. The laser plasma flame generator is used to control the operation of the laser plasma flame gun.

[0012] A transfer mechanism is disposed above the center of the base, and its movable end is connected to the center of the laser plasma flame gun. The transfer mechanism is used to adjust the position of the laser plasma flame gun.

[0013] A gantry frame is disposed at the center of the top surface of the base, and the top surface of the gantry frame is connected to the transfer mechanism. The gantry frame is used to provide support for the transfer mechanism.

[0014] Furthermore, baffles are provided on both sides of the top surface of the base and on the bottom surface of the loading mechanism, and the baffles are used to guide and limit the loading mechanism.

[0015] Furthermore, the material loading mechanism includes two parallel horizontal bars and two parallel vertical bars. The two horizontal bars are perpendicular to the two vertical bars, and the horizontal bars are located above the vertical bars. The two intersecting horizontal bars and vertical bars are connected by a sliding assembly.

[0016] Each of the sliding components is provided with a first electric flatbed cart at its bottom end, and the bottom end of the first electric flatbed cart is rotatably connected to the top surface of the base.

[0017] Furthermore, the sliding component includes a positioning block, with a first guide groove for inserting a crossbar on the upper side wall of the positioning block and a second guide groove for inserting a longitudinal bar on the lower side wall of the positioning block.

[0018] The positioning block has a first screw hole on its side wall above the second guide groove, and a first positioning bolt is rotatably connected to the inner cavity of the first screw hole. The positioning block has a second screw hole on its side wall below the first guide groove, and a second positioning bolt is rotatably connected to the inner cavity of the second screw hole.

[0019] Furthermore, the transfer mechanism includes a fixed frame, an electric push rod is inserted into the middle of the fixed frame, and a limit frame is installed at the bottom output end of the electric push rod;

[0020] A through hole is provided in the middle of the top surface of the gantry frame, and the electric push rod passes through the through hole.

[0021] Furthermore, the transfer mechanism also includes two guide rails, which are disposed on the top surface of the gantry and located on both sides of the through hole. The guide rails are used to smoothly guide the second electric flatbed cart to slide.

[0022] Furthermore, it also includes a purification mechanism, which is disposed at the movable end of the transfer mechanism and located outside the laser plasma flame gun. The purification mechanism is used to treat the smoke generated during cutting.

[0028] 3. Beneficial effects

[0029] Compared with the prior art, the advantages of this invention are:

[0030] This solution, through its base, not only secures the gantry frame but also provides a stable moving surface for the material-carrying mechanism. Therefore, when processing extra-large and extra-thick plates, workers can first use lifting equipment to hoist the plates onto the material-carrying mechanism. The mechanism then moves the plates, adjusting their position to reach the laser plasma torch. Since the transfer mechanism is mounted on the gantry frame, and the laser plasma torch is installed at its telescopic end, while a laser plasma torch is also mounted on one side of the gantry frame, the movement of the transfer mechanism allows for adjustment of the laser plasma torch's position. This facilitates the laser plasma torch's cutting of the extra-large and extra-thick plates on the material-carrying mechanism, significantly improving the efficiency of the cutting process.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Example:

[0042] Please see Figure 1-2A composite processing device for ultra-large and ultra-thick plates based on laser plasma flame includes a base 1, and further includes: a material loading mechanism 2, disposed on the top surface of the base 1, used to support and move the ultra-large and ultra-thick plates; a laser plasma flame gun 4, disposed directly above the center of the base 1, used to process the ultra-large and ultra-thick plates on the material loading mechanism 2; and a laser plasma flame machine 5, disposed above one side of the base 1, and the laser plasma flame... The output end of the flame generator 5 is connected to the input end of the laser plasma flame gun 4. The laser plasma flame generator 5 is used to control the operation of the laser plasma flame gun 4. The transfer mechanism 6 is located above the middle of the base 1, and the movable end of the transfer mechanism 6 is connected to the middle of the laser plasma flame gun 4. The transfer mechanism 6 is used to adjust the position of the laser plasma flame gun 4. The gantry 7 is located in the middle of the top surface of the base 1, and the top surface of the gantry 7 is connected to the transfer mechanism 6. The gantry 7 is used to provide support for the transfer mechanism 6.

[0043] The base 1 not only secures the gantry 7 but also provides a stable moving surface for the loading mechanism 2. Therefore, when processing ultra-large and ultra-thick plates, workers can first use lifting equipment to hoist the plates onto the loading mechanism 2. The loading mechanism 2 then moves the plates, adjusting their position to reach the laser plasma torch 4. Since the transfer mechanism 6 is mounted on the gantry 7, and the laser plasma torch 4 is mounted on its telescopic end, and a laser plasma torch 5 is mounted on one side of the gantry 7, the position of the laser plasma torch 4 can be adjusted through the operation of the transfer mechanism 6. This facilitates the laser plasma torch 4 in cutting the ultra-large and ultra-thick plates on the loading mechanism 2, improving the efficiency of ultra-large and ultra-thick plate cutting.

[0044] See Figure 1 , Figure 2 The top surface of the base 1 and both sides of the bottom surface of the loading mechanism 2 are provided with baffles 3. The two baffles 3 can guide and limit the loading mechanism 2, thereby preventing the loading mechanism 2 from slipping off the base 1 during movement.

[0045] See Figure 1 , Figure 3 and Figure 4The loading mechanism 2 includes two parallel horizontal bars 21 and two parallel vertical bars 22. The two horizontal bars 21 are perpendicular to the two vertical bars 22 and are located above the vertical bars 22. The two intersecting horizontal bars 21 and vertical bars 22 are connected by sliding components 23. Each sliding component 23 has a first electric flatbed trolley 24 at its bottom end, and the bottom end of the first electric flatbed trolley 24 is rotatably connected to the top surface of the base 1. Through the four sliding components 23 in the loading mechanism 2, the corresponding first electric flatbed trolley 24 can be installed, and the intersecting horizontal bars 21 and vertical bars 22 can be inserted and installed. Since the horizontal bars 21 and vertical bars 22 are slidably connected to the sliding components 23, the position of the four sliding components 23 can be adjusted by moving the first electric flatbed trolley 24, thereby synchronously adjusting the support position of the two horizontal bars 21 and the two vertical bars 22, so as to be able to support and move ultra-large and ultra-thick plates of different sizes.

[0046] See Figure 3 , Figure 4 The sliding component 23 includes a positioning block 231. A first guide groove 232 for inserting a crossbar 21 is provided on the upper side wall of the positioning block 231, and a second guide groove 233 for inserting a longitudinal bar 22 is provided on the lower side wall of the positioning block 231. A first screw hole is provided on the side wall of the positioning block 231 above the second guide groove 233, and a first positioning bolt 234 is rotatably connected to the inner cavity of the first screw hole. A second screw hole is provided on the side wall of the positioning block 231 below the first guide groove 232, and a second positioning bolt 235 is rotatably connected to the inner cavity of the second screw hole.

[0047] The positioning block 231 in the sliding component 23 can be installed on the first electric flatbed 24 and also provides space for the first guide groove 232 and the second guide groove 233, so that the corresponding crossbars 21 and longitudinal bars 22 can be easily inserted. This allows the crossbars 21 and longitudinal bars 22 to slide and adjust on the positioning block 231. After the positions of the crossbars 21 and longitudinal bars 22 are adjusted, the first positioning bolt 234 in the first screw hole and the second positioning bolt 235 in the second screw hole can be rotated to lock and position the corresponding crossbars 21 and longitudinal bars 22 in the first guide groove 232 and the second guide groove 233, so as to ensure the stability of the crossbars 21 and longitudinal bars 22 when moving the ultra-large and ultra-thick plates.

[0048] See Figure 1 , Figure 5The transfer mechanism 6 includes a fixed frame 61, an electric push rod 62 inserted in the middle of the fixed frame 61, and a limit frame 63 installed at the bottom output end of the electric push rod 62. A second electric flatbed trolley 64 is provided on both sides of the bottom of the fixed frame 61. A through hole is opened in the middle of the top surface of the gantry frame 7, and the electric push rod 62 passes through the through hole. The transfer mechanism 6 also includes two guide rails 65, which are set on the top surface of the gantry frame 7 and located on both sides of the through hole. The guide rails 65 are used to guide the second electric flatbed trolley 64 to slide smoothly.

[0049] The two guide rails 65 in the transfer mechanism 6 can be installed on the top surface of the gantry 7 and provide a moving track for the two second electric flatbed carts 64, thereby improving the stability of the two second electric flatbed carts 64 when moving left and right. Since the top surfaces of the two second electric flatbed carts 64 are connected by a fixing frame 61, and an electric push rod 62 is inserted in the middle of the fixing frame 61, and a limit frame 63 is installed at the bottom output end of the electric push rod 62, the electric push rod 62 on the fixing frame 61 can be used to adjust the vertical position of the limit frame 63, and the horizontal position of the limit frame 63 can be adjusted synchronously when the second electric flatbed carts 64 move left and right, thereby synchronously adjusting the position of the laser plasma flame gun 4 located on the limit frame 63.

[0050] See Figure 1 , Figure 2 , Figure 6 and Figure 7 It also includes a purification mechanism 8, which is located at the movable end of the transfer mechanism 6 and outside the laser plasma flame gun 4. The purification mechanism 8 is used to treat the smoke generated during cutting. The purification mechanism 8 includes a support frame 81 located at one end of the top surface of the limiting frame 63. A wind collection hood 82 is inserted into one side of the top surface of the support frame 81. A spring tube 83 is connected to the top of the wind collection hood 82. One end of the spring tube 83 is connected to an air handling assembly 85 through an exhaust fan 84. The air handling assembly 85 is used to purify the smoke that is drawn in.

[0051] The support frame 81 in the purification mechanism 8 can be installed on the limiting frame 63 and the air collection hood 82 can also be installed. Since the top of the air collection hood 82 is connected to the spring tube 83, and one end of the spring tube 83 is connected to the air handling assembly 85 through the exhaust fan 84, the exhaust fan 84 can provide upward smoke extraction power to the air collection hood 82, thereby extracting the smoke generated when the laser plasma flame gun 4 processes ultra-large and ultra-thick plates, and then transporting it to the air handling assembly 85 so that the air handling assembly 85 can purify the smoke.

[0052] See Figure 6 , Figure 7The air handling unit 85 includes an air filter box 851. An air supply duct 852 and an exhaust duct 853 are respectively embedded and connected to the two side walls of the air filter box 851. One end of the air supply duct 852 is connected to the output end of the exhaust fan 84. The inner cavity of the air filter box 851 is equipped with a flame-retardant filter sponge 854 and an activated carbon mesh plate 855, with the flame-retardant filter sponge 854 located near the air supply duct 852. Through the air filter box 851 in the air handling unit 85, it can be connected to the exhaust fan 84 via the air supply duct 852, and the exhaust duct 853, flame-retardant filter sponge 854, and activated carbon mesh plate 855 can be installed. Smoke can be introduced into the air filter box 851 through the air supply duct 852, allowing the flame-retardant filter sponge 854 and activated carbon mesh plate 855 to filter and purify the smoke, thereby reducing the pollution of workers' health and the overall working environment. The treated smoke can be discharged through the exhaust duct 853.

[0053] See Figure 1 , Figure 2 A bracket 9 is provided on one side wall of the gantry 7. The bracket 9 can provide support for the laser plasma flame machine 5, the exhaust fan 84 and the air handling unit 85, thereby improving the stability of the above equipment.

[0054] In use: The base 1 can both fix the gantry 7 and provide a stable moving plane for the material loading mechanism 2. Therefore, when processing ultra-large and ultra-thick plates, the operator can first use a lifting device to hoist the ultra-large and ultra-thick plates onto the material loading mechanism 2. Then, the material loading mechanism 2 can carry the ultra-large and ultra-thick plates and move them, thereby adjusting the position of the ultra-large and ultra-thick plates and bringing them to the laser plasma flame gun 4. Since the transfer mechanism 6 is installed on the gantry 7 and the laser plasma flame gun 4 is installed at the telescopic end of the transfer mechanism 6, and the laser plasma flame machine 5 is installed on one side of the gantry 7, the position of the laser plasma flame gun 4 can be adjusted by the operation of the transfer mechanism 6. This facilitates the laser plasma flame gun 4 to cut the ultra-large and ultra-thick plates on the material loading mechanism 2, improving the efficiency of cutting ultra-large and ultra-thick plates.

[0055] Two stop bars 3 guide and limit the loading mechanism 2, preventing it from slipping off the base 1 during movement. Four sliding components 23 in the loading mechanism 2 allow for the installation of the corresponding first electric flatbed trolley 24 and the insertion and installation of the intersecting crossbars 21 and longitudinal bars 22. Since the crossbars 21 and longitudinal bars 22 are slidably connected to the sliding components 23, the movement of the first electric flatbed trolley 24 adjusts the position of the four sliding components 23, thereby synchronously adjusting the support positions of the two crossbars 21 and two longitudinal bars 22 to support and move extra-large and extra-thick plates of different sizes. The fixed... Positioning block 231 can be installed on the first electric flatbed trolley 24 and also provides space for the first guide groove 232 and the second guide groove 233, so as to facilitate the insertion of the corresponding crossbar 21 and longitudinal bar 22. In addition, it can facilitate the sliding adjustment of the crossbar 21 and longitudinal bar 22 on the positioning block 231. After the position of the crossbar 21 and longitudinal bar 22 is adjusted, the first positioning bolt 234 in the first screw hole and the second positioning bolt 235 in the second screw hole can be rotated to lock and position the corresponding crossbar 21 and longitudinal bar 22 in the first guide groove 232 and the second guide groove 233, so as to ensure the stability of the crossbar 21 and longitudinal bar 22 in the movement of the ultra-large and ultra-thick plate.

[0056] The two guide rails 65 in the transfer mechanism 6 can be installed on the top surface of the gantry 7 and can also provide moving tracks for the two second electric flatbed carts 64, thereby improving the stability of the two second electric flatbed carts 64 when moving left and right. Since the top surfaces of the two second electric flatbed carts 64 are connected by a fixing frame 61, and an electric push rod 62 is inserted in the middle of the fixing frame 61, and a limit frame 63 is installed at the bottom output end of the electric push rod 62, the electric push rod 62 on the fixing frame 61 can be used to adjust the vertical position of the limit frame 63, and the horizontal position of the limit frame 63 can be adjusted synchronously when the second electric flatbed carts 64 move left and right, thereby synchronously adjusting the position of the laser plasma flame gun 4 located on the limit frame 63.

[0057] The support frame 81 in the purification mechanism 8 can be installed on both the limiting frame 63 and the air collection hood 82. Since the top of the air collection hood 82 is connected to a spring tube 83, and one end of the spring tube 83 is connected to an air handling unit 85 via an exhaust fan 84, the exhaust fan 84 provides upward suction power to the air collection hood 82. This allows the fumes generated when the laser plasma flame gun 4 processes ultra-large and ultra-thick plates to be extracted and transported to the air handling unit 85, enabling the air handling unit 85 to effectively process the fumes. The air is purified through the air filter box 851 in the air handling unit 85. It can be connected to the exhaust fan 84 via the air supply duct 852, and the exhaust pipe 853, the flame-retardant filter sponge 854, and the activated carbon mesh plate 855 can be installed. The flue gas can be introduced into the air filter box 851 through the air supply duct 852, so that the flame-retardant filter sponge 854 and the activated carbon mesh plate 855 can filter and purify the flue gas, thereby reducing the pollution of the flue gas to the health of workers and the entire working environment. The treated flue gas can be discharged through the exhaust pipe 853.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
