Description

Technical Field

[0001] The present invention relates to the technical field of cutting for steel structure processing, and more particularly to a cutting device for steel structure processing. Background Art

[0002] Steel structure refers to a structural system made of steel as the main material through specific design and manufacturing processes. Steel structure processing is the process of processing and manufacturing steel. Steel structure processing includes cutting, welding, forming, surface treatment and other devices. Among them, the cutting device is particularly important. It not only determines the dimensional accuracy and geometric shape accuracy of steel processing, but also directly affects the surface quality, structural performance and matching of subsequent assembly of the material. It ensures the safety, stability and durability of steel materials during use, and is an indispensable link in achieving high-quality steel structure manufacturing.

[0003] When using existing cutting devices for steel structure processing, the steel is usually placed on the workbench and then firmly clamped by a fixing mechanism to prevent displacement during cutting. The motor is then started to drive the disc cutter to rotate at high speed. At the same time, the hydraulic rod is used to control the motor housing to slowly move downward, so that the rotating disc cutter gradually cuts into the surface of the steel. The hydraulic rod works continuously to ensure that the tool is stable and deep, completing efficient and accurate cutting of the steel. After cutting is completed, the hydraulic rod is lifted up and reset, the motor is turned off, the fixing mechanism is loosened, the processed workpiece is taken out and the site is cleaned up to prepare for the next cycle of operation.

[0004] When the existing technology is actually used, due to the intense friction between the disc cutter and the steel during the cutting process, a large amount of heat is generated, causing the local temperature in the cutting area to rise sharply. This high-temperature environment can easily cause thermal deformation of the steel surface, resulting in a decrease in the material's dimensional accuracy, thereby reducing the processing quality and assembly accuracy of the steel structure.

[0022] Example 1: Please refer to Figures 1-11 A cutting device for steel structure processing includes a workbench 1, a support frame 102 is installed on the upper surface of the workbench 1, and an adjusting cutting component 2 is installed on the lower surface of the support frame 102.

[0023] Specifically, the adjustment cutting assembly 2 includes a hydraulic rod 206 installed on the lower surface of the support frame 102. By starting the hydraulic rod 206, the connecting block 207 together with the motor housing and the disc cutter 205 below are moved downward as a whole until the disc cutter 205 is close to the steel body 104. When cutting is required, the disc cutter 205 is driven to rotate at high speed by the motor 208, and the hydraulic rod 206 continues to apply a stable pressure downward to make the disc cutter 205 gradually cut into the steel body 104 to complete the cutting operation. After the cutting is completed, the hydraulic rod 206 retracts and resets, and the disc cutter 205 is lifted to prepare for the next round of cutting work; one end of the hydraulic rod 206 is fixedly connected to the connecting block 207, and the connecting block 207 is fixedly connected to the connecting block 207. A protective sleeve 103 is fixedly connected to the side of 07, and the adjusting cutting assembly 2 includes a U-shaped plate fixedly connected to the outer surface of the support frame 102, and a motor 201 is fixedly connected to the side of the U-shaped plate, and the output shaft end of the motor 201 is fixedly connected to the screw 202, and the outer surface of the screw 202 is threadedly connected to the sleeve 203, and the lower surface of the sleeve 203 is connected to the hydraulic rod 206. A slide rail 204 is installed inside the support frame 102, and the outer surface of the sleeve 203 is slidably connected to the inner cavity of the slide rail 204, and the side of the connecting block 207 is fixedly connected to the motor housing, and the inner cavity of the motor housing is fixedly connected to the motor 2 208, and the output shaft end of the motor 208 is fixedly connected to the disc cutter 205.

[0024] The bottom of the workbench 1 is fixedly connected with a plurality of supporting legs 101, and a recycling chamber is opened inside the workbench 1. The inner cavity of the recycling chamber is installed with a waste recycling component 6, and the waste recycling component 6 includes a waste recycling box 601 slidably connected to the inside of the recycling chamber. The upper surface of the recycling chamber is fixedly connected with a filter screen 602. The debris generated during cutting will fall into the waste recycling box 601 through the holes in the filter screen 602 for storage, so that the debris recovery work can be completed automatically. The upper surface of the filter screen 602 is installed with a fixed component 3, and the fixed component 3 includes a plurality of support blocks 301 fixedly connected to the upper surface of the filter screen 602. The steel body 104 is placed on the upper surface of the support block 301, and the upper surface of the support block 301 is fixedly connected to the connecting plate 302, and the interior of the connecting plate 302 is installed with the slide rail 2 304, and the inner cavity of the slide rail 2 304 is installed with a threaded rod 303, and the outer surface of the threaded rod 303 is threadedly connected to the moving block 305, and the outer surface of the moving block 305 is slidably connected to the inner cavity of the slide rail 2 304, and one end of the threaded rod 303 is inserted into the outer surface of the connecting plate 302 and is fixedly connected to a circular plate, and the side of the moving block 305 is fixedly connected to the fixed plate 306, and the outer surface of the fixed plate 306 is in contact with the upper surface of the steel body 104.

[0025] Furthermore, the steel body 104 is first placed on the two support blocks 301. After it is placed, the circular plate is rotated to drive the threaded rod 303 to rotate. When the threaded rod 303 rotates, it drives the moving block 305 to move along the track of the second slide rail 304. When the moving block 305 moves, it drives the fixed plate 306 to move downward, so that the fixed plate 306 abuts against the steel body 104. Then, the motor 1 201 is started to drive the screw rod 202 to rotate. When the screw rod 20 When rotating, the sleeve 203 is driven to move along the track of the slide rail 1 204, ensuring that the disc cutter 205 is aligned with the position required for cutting the steel body 104. Then, the motor 1 201 is turned off, and the hydraulic rod 206 is started to drive the connecting block 207 to move, so that the connecting block 207 drives the disc cutter 205 to contact the surface of the steel body 104. At the same time, the motor 208 is started to drive the disc cutter 205 to rotate, so that the disc cutter 205 cuts the steel body 104.

[0026] Example 2: Reference Figures 1-11 This is the second new embodiment of the present invention. Based on the previous embodiment, a simulation trigger component 4 is installed inside the adjustment cutting component 2, and an automatic cooling component 5 is installed on the outer surface of the simulation trigger component 4.

[0027] Specifically, the simulation trigger component 4 includes a simulation sleeve 402 installed inside the protective sleeve 103, and the simulation block 401 is fixedly connected to the interior of the simulation sleeve 402. The interior of the protective sleeve 103 is respectively installed with a spray chamber 413 and a nitrogen chamber 501 through multiple partitions. The simulation trigger component 4 includes a touch plate 404 fixedly connected to the upper surface of the simulation block 401. The touch plate 404 is made of shape memory alloy material. Using its unique shape memory effect, when the disc knife 205 and the simulation block 401 generate heat by friction, the touch plate 404 expands and deforms due to the heat, pushing the touch rod 405 to trigger the spray button 406 to start the spraying of lubricating oil, realizing on-demand lubrication and preventing the heat generated during the cutting process from causing overheating of the tool. The shape memory alloy does not require external energy and can complete the action by relying on its own thermal response. It can be replaced by electroactive polymers or magnetostrictive materials.

[0028] One end of the touch plate 404 is fixedly connected to a touch rod 405, and the top of the inner cavity of the simulation sleeve 402 is fixedly connected to a spray button 406. The outer surface of the spray button 406 is sleeved with a spring 408, and one end of the spring 408 is connected to the touch protrusion 407. The simulation trigger component 4 also includes a branch pipe 411 fixedly connected to the inside of the spray chamber 413, and the outer surface of the branch pipe 411 is fixedly connected to a plurality of atomizing spray guns 412. The outer surface of the branch pipe 411 is fixedly connected to a pump 2. When the surface lubricating oil of the disc cutter 205 is insufficient or the oil film fails, the simulation block 401 is connected to the simulation block 401. The frictional resistance between the two parts increases, resulting in a significant temperature rise. The heat is sensed in real time by the touch plate 404 above the simulation block 401. The touch plate 404 is deformed after being heated, pushing the touch rod 405 to move, thereby triggering the spray button 406, starting the second pump to transport the cooled lubricating oil to the atomizing spray gun 412, and evenly spraying it onto the surface of the disc cutter 205. Therefore, through the direct contact and friction between the simulation block 401 and the disc cutter 205, the lubrication status can be accurately detected, and "on-demand spraying" can be achieved, which effectively prevents the disc cutter 205 from overheating and wear, and improves cutting stability and lubrication efficiency.

[0029] The automatic cooling assembly 5 includes a delivery pipe 504 installed inside the nitrogen chamber 501. A plurality of nozzles 505 are fixedly connected to the outer surface of the delivery pipe 504. A plurality of condensers 507 are fixedly connected to the inside of the spray chamber 413 and the nitrogen chamber 501. The condenser 507 is a device for cooling a medium (such as lubricating oil or nitrogen). It uses an external cooling source (such as cooling water or refrigerant) to reduce the temperature of the medium flowing through it. The condenser 507 reduces the temperature of the nitrogen and lubricating oil to a preset value by circulating the cooling medium. The condenser 507 can be replaced by a plate-type heat exchanger. A nitrogen tank 506 and a lubricating oil tank 409 are fixedly connected to the upper surface of the support frame 102. The inner cavities of the nitrogen tank 506 and the lubricating oil tank 409 are respectively connected to a connecting pipe 502 and a lubricating oil pipe 410. One end of the connecting pipe 502 is fixedly connected to two nitrogen pipes 503. The two nitrogen pipes 503 are respectively connected to the inner cavities of the two nitrogen chambers 501. The other end of the lubricating oil pipe 410 is connected to the inner cavity of the spray chamber 413. The outer surfaces of the connecting pipe 502 and the lubricating oil pipe 410 are fixedly connected to a pump 1.

[0030] The nitrogen chamber 501 and the nitrogen box 506 are filled with nitrogen, and the lubricating oil tank 409 and the spray chamber 413 are filled with lubricating oil. After being cooled, the nitrogen is sprayed into the cutting area through the nozzle 505, which quickly takes away the heat generated during the cutting process, preventing the steel body 104 and the disc cutter 205 from thermal deformation due to high temperature, thereby improving the processing accuracy. At the same time, nitrogen, as an inert gas, can form a protective layer in the cutting area, reducing the risk of oxidation on the surface of the steel body 104; the lubricating oil can effectively reduce the friction between the disc cutter 205 and the steel body 104, and the low-temperature lubricating oil directly contacts the high-temperature disc cutter 205, quickly taking away the heat and preventing the tool from overheating; the outer surfaces of the nitrogen chamber 501 and the spray chamber 413 are fixedly connected with protective pads 5 09. The inner cavities of the nitrogen chamber 501 and the spray chamber 413 are fixedly connected with temperature sensor 2 508 and temperature sensor 1 414 respectively. The outer surface of the delivery pipe 504 is fixedly connected with an air pump. The outer surface of the simulation sleeve 402 is fixedly connected with a protective pad 1 403. Both protective pad 2 509 and protective pad 1 403 are made of heat-insulating materials. When the disc knife 205 and the simulation block 401 generate heat through friction, the heat can be effectively blocked by protective pad 1 403 to avoid thermal impact on other components. Protective pad 2 509 maintains the low temperature environment in the nitrogen chamber 501 and the spray chamber 413 to ensure that the cooling medium can function in the best condition. Protective pad 2 509 and protective pad 1 403 can be replaced by glass fiber and polyurethane foam.

[0031] Furthermore, the condenser pipes 507 in the nitrogen chamber 501 and the spray chamber 413 are opened to cool the nitrogen in the two nitrogen chambers 501 and the lubricating oil in the spray chamber 413 to a preset value, and then the condenser pipes 507 are closed. When the disc cutter 205 cuts the steel body 104, the air pump is started to transport the cooled nitrogen in the nitrogen chamber 501 to the nozzle 505 through the delivery pipe 504, and the nitrogen is sprayed between the disc cutter 205 and the steel body 104 through the multiple inclined nozzles 505, thereby achieving rapid cooling. When the disc cutter 205 rotates, the nitrogen in the nitrogen chamber 501 is transported to the nozzle 505 through the delivery pipe 504. When the disc 205 rotates, it will rub against the simulation block 401 that contacts its surface. The heat generated by the friction will be transferred to the touch plate 404 through the simulation block 401, causing the touch plate 404 to expand and extend outward due to the heat, thereby driving the push-touch rod 405 to drive the touch protrusion 407 to press the spray button 406, so that the second pump is turned on and the cooled lubricating oil in the spray chamber 413 is transported to the atomizing spray gun 412 through the branch pipe 411. The atomizing spray gun 412 converts the lubricating oil into mist and sprays it onto the surface of the disc cutter 205. The lubricating oil can be quickly dried by continuously spraying nitrogen.

[0032] Working principle: First, place the steel body 104 on the two support blocks 301. When it is placed, rotate the circular plate to drive the threaded rod 303 to rotate. When the threaded rod 303 rotates, it will drive the moving block 305 to move along the track of the second slide rail 304. When the moving block 305 moves, it will drive the fixed plate 306 to move downward, so that the fixed plate 306 abuts against the steel body 104. And so on, the other fixed plate 306 fixes the steel body 104 to ensure that the steel body 104 does not Displacement will occur to improve the processing accuracy. At the same time, the power supplies and controllers of the two pumps 1 are started, so that one of the pumps 1 delivers the lubricating oil in the lubricating oil tank 409 to the spray chamber 413 through the lubricating oil pipe 410, and the other pump delivers the nitrogen in the nitrogen tank 506 to the two nitrogen pipes 503 through the connecting pipe 502, and then delivers it to the two nitrogen chambers 501 through the two nitrogen pipes 503. When the nitrogen and lubricating oil in the nitrogen chamber 501 and the spray chamber 413 are filled, the two pumps 1 are turned off.

[0033] Then start the power supply and controller of the condenser 507 in the nitrogen chamber 501 and the spray chamber 413 respectively, so that the condenser 507 is turned on, thereby cooling the nitrogen in the two nitrogen chambers 501, and monitoring its temperature in real time between -5-15 degrees Celsius through the temperature sensor 2 508. When the preset temperature is reached, the condenser 507 will be automatically closed to avoid overcooling. At the same time, the condenser 507 in the spray chamber 413 cools the lubricating oil, and monitors its temperature in real time through the temperature sensor 1 414 to ensure that its temperature is between -1-5 degrees Celsius. When the preset temperature is reached, the condenser 507 will be automatically closed.

[0034] Subsequently, the power supply and controller of the motor 201 are started, so that the motor 201 drives the screw rod 202 to rotate. When the screw rod 202 rotates, the sleeve 203 is driven to move along the track of the slide rail 204, ensuring that the disc cutter 205 coincides with the position required for cutting the steel body 104. Then, the power supply and controller of the motor 201 are turned off. At the same time, the slide rail 204 can prevent the sleeve 203 from rotating as the screw rod 202 rotates, so as to play a supporting and limiting role for the sleeve 203. Then, start the power supply and controller of the hydraulic rod 206, so that the hydraulic rod 206 drives the connecting block 207 to move, and the connecting block 207 drives the motor housing below to move, so that the disc cutter 205 abuts against the surface of the steel body 104. At the same time, start the power supply and controller of the motor 208, so that the motor 208 drives the disc cutter 205 to rotate, so that the disc cutter 205 cuts the steel body 104. The protective cover 103 can prevent the debris generated during the cutting process from flying everywhere.

[0035] At the same time, the air pump is started to transport the cooled nitrogen in the nitrogen chamber 501 to the nozzle 505 through the delivery pipe 504, and the nitrogen is sprayed between the disc cutter 205 and the steel body 104 through multiple inclined nozzles 505, thereby achieving rapid cooling, avoiding thermal deformation of the steel due to high temperature, and improving the processing refrigeration and assembly accuracy of the steel structure; at the same time, convection is formed between the two groups of nozzles 505, which on the one hand accelerates the heat dissipation in the cutting area, and on the other hand, the air flow can blow the debris through the filter 602 to the waste recovery box 601 for centralized storage, so that the waste generated during the cutting process can be cleaned up.

[0036] When the disc knife 205 rotates, it rubs against the simulation block 401 that contacts its surface. The heat generated by the friction is transferred to the touch plate 404 through the simulation block 401, causing the touch plate 404 to expand and extend outward due to the heat, thereby driving the touch rod 405 to move upward. When the touch rod 405 moves, it touches the touch protrusion 407, which further presses the touch protrusion 407 to press the spray button 406. At the same time, when the touch protrusion 407 moves, it drives the spring 408 to compress, causing the spray button 406 to turn on the power supply and controller of the pump 2, so that the pump 2 can spray the cooled lubricating oil in the spray chamber 413 through the branch pipe 41 1 is transported to the atomizing spray gun 412, so that the atomizing spray gun 412 converts the lubricating oil into mist and sprays it onto the surface of the disc cutter 205. The lubricating oil can be quickly dried by continuously spraying nitrogen, so that an oil film can be quickly formed on the surface of the disc cutter 205, which can protect the worn area of ​​the disc cutter 205. At the same time, the cooled lubricating oil can cool the disc cutter 205 again and prevent the debris generated during cutting from adhering to the surface of the disc cutter 205. The protective pad 403 on the surface of the simulation sleeve 402 can isolate the heat between the heat simulation block 401 and the disc cutter 205 from affecting the protective sleeve 103 and other areas of the disc cutter 205.

[0037] When the temperature of the simulation block 401 drops, the touch plate 404 will return to its original state. During this process, the touch rod 405 will move away from the touch protrusion 407, so that the touch protrusion 407 is reset by the elasticity of the spring 408, thereby closing the spray button 406 and stopping the spraying of the lubricating oil. In this way, the lubricating oil can be sprayed according to the actual needs of the disc knife 205, thereby realizing "spraying on demand", avoiding waste of lubricating oil, and reducing environmental pollution.
