Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and in particular to a cutting device and a cutting method for producing and processing metal guardrails. Background Art

[0002] In the production process of metal guardrails, cutting is a crucial link. The design of metal guardrails requires specific dimensions. Cutting can ensure that each component meets these requirements to adapt to the installation environment. In the process of cutting metal guardrails, CNC cutting machines are often used to cut metal. CNC cutting machines can accurately control the movement of the tool through computer programs, so they can achieve extremely high cutting accuracy and reduce errors.

[0003] In the prior art, although CNC cutting machines can achieve high-precision cutting during the process of processing and cutting metal guardrails, during the cutting process, CNC cutting machines use lasers for cutting, and the laser cutting method will generate extremely high temperatures. High temperatures can cause metals to melt or evaporate rapidly, thereby generating gas and smoke. Most existing CNC machine tools use water spray dust removal to deal with smoke in the air. By spraying water mist into the working area, smoke particles are settled and suspended particles in the air are reduced. However, a large amount of water resources are consumed during the processing process, resulting in a waste of resources.

[0023] The working principle of this embodiment is as follows: when in use, during the process of metal guardrail processing and production, when the metal guardrail needs to be cut, the required metal rod is first placed on the top of the leak plate 6. In order to ensure that the metal rod does not move during the cutting process, the second forward and reverse motor 402 is started to drive the bidirectional threaded rod 403 to rotate, and then drive the two clamping plates 404 to move towards each other until the metal rod is clamped and fixed. Figure 5As shown, the limiting tube 405 limits the two clamping plates 404, so that the clamping plates 404 can only move horizontally along the bidirectional threaded rod 403. When the metal rod is fixed, the cutting head body 307 is started, wherein the cutting head body 307 uses the high energy density of the laser beam to locally heat the metal material to above the melting point, and then blows away the molten metal through high-pressure gas, thereby achieving cutting. Then, the servo motor 204 is started first to drive the driving shaft 205 to rotate, thereby driving the driving gear 206 to rotate, so that the driving gear 206 moves horizontally along the direction of the first tooth row 207, thereby driving the mounting frame 301 to move, and then the other moving rod 202 is also moved along the first tooth row 207. The limiting rod 201 matched therewith moves, thereby realizing the horizontal movement of the cutting head body 307. When the cutting head body 307 moves to a position parallel to the position where the metal rod needs to be cut, the servo motor 204 is turned off, and then the stepping motor 304 is started to drive the rotating shaft 305 to rotate, thereby driving the driving gear 306 to rotate, so that the cutting head body 307 moves horizontally along the direction of the second tooth row 302 until the cutting head body 307 moves to the position where the metal rod needs to be cut. The cutting head body 307 can cut the metal rod. During the cutting process, extremely high temperature will be generated, and the high temperature will cause the metal to melt and evaporate rapidly, thereby generating gas and smoke. At this time, Figure 1 As shown, the two moving rods 202 will drive the connecting rod 501 to move during the movement, so that the suction fan 509 moves to a position parallel to the cutting head body 307, and then the first forward and reverse motor 503 is started to drive the screw rod 504 to rotate, thereby driving the slide plate 505 to move along the inside of the slide groove 502 until the suction fan 509 moves to a position corresponding to the cutting head body 307, and then the suction fan 509 can be started to absorb gas outward, so that the smoke generated during the metal cutting process is adsorbed into the inside of the processing tank 506 under the action of negative pressure, and at the same time, the two semiconductor refrigeration sheets 510 are electrically connected to the external power supply, wherein the two semiconductor The cold surfaces of the refrigeration plates 510 correspond to the interior of the treatment tank 506, so that the interior of the treatment tank 506 is in a low-temperature state. The semiconductor refrigeration plates 510 are based on the thermoelectric effect, that is, when direct current passes through a couple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the couple, thereby achieving the purpose of refrigeration. By low-temperature treatment of the treatment tank 506, the water vapor in the flue gas entering the treatment tank 506 is cooled, liquefied, and retained on the surfaces of the multiple water tanks 507, and flows downward along the water tanks 507 to the interior of the water baffle 511, and finally enters the interior of the water storage tank 514 through the water outlet pipe 512 for storage. Fig. 9As shown, harmful substances in water can be absorbed by setting the adsorption plate 513, wherein the adsorption plate 513 is an ultrafiltration membrane, and the pore size of the ultrafiltration membrane is larger than that of the reverse osmosis membrane. It can filter out large molecular organic matter, colloids, bacteria, etc. in the water. Its filtering principle is screening, that is, to separate substances according to molecular size. Water and small molecular substances can pass through the pores of the ultrafiltration membrane, while large molecular harmful substances are retained, thereby achieving the absorption and purification of water vapor. The flue gas entering the treatment tank 506 is purified by the activated carbon 516 and then flows out through the exhaust pipe 515. Among them, the activated carbon 516 has a rich microporous structure, and the pore size of these micropores is slightly larger than that of the harmful gas. The body molecules can adsorb harmful gas molecules on their surface, thereby achieving the purpose of purifying the gas. In addition, the particulate matter in the flue gas falls to the surface of the flip plate 520 under the action of its own gravity, and then the drive motor 518 is started to drive the top of the flip plate 520 to rotate downward, so that the particulate matter retained on its surface falls to the bottom of the treatment tank 506 under the action of its own gravity, thereby achieving effective absorption and subsequent treatment of the flue gas generated when the CNC cutting machine cuts metal, reducing environmental pollution while saving water resources, and solving the problem of waste of water resources in the prior art when the CNC cutting machine uses water spray to remove gas during the production and processing of metal guardrails.

[0024] Embodiment 2: According to Figure 1-9 As shown, a cutting method of a cutting device for metal guardrail production and processing includes the following steps: first, placing the required metal rod on the top of the drain plate 6, starting the second forward and reverse motor 402, driving the two clamping plates 404 to move toward each other, and clamping and fixing the metal rod; Step 2: Start the cutting head body 307, start the servo motor 204, drive the mounting frame 301 to move, drive the two moving rods 202 to move horizontally along the limit rod 201, and then realize the horizontal movement of the cutting head body 307, until the cutting head body 307 moves to a position parallel to the position where the metal rod needs to be cut; Step 3: Start the stepper motor 304 to drive the cutting head body 307 to move to the position where the metal rod needs to be cut, and then cut the metal rod; Step 4: Start the first forward and reverse motor 503, and move the air suction fan 509 to a position corresponding to the cutting head body 307, and then start the air suction fan 509, so that the smoke enters the low-temperature treatment tank 506 under the action of the pressure difference; Step 5: The water vapor is pre-cooled and liquefied and retained on the surface of the multiple water tanks 507, and finally purified by the adsorption plate 513, and then enters the interior of the water storage tank 514 through the water outlet pipe 512 for storage; Step 6: The flue gas entering the treatment tank 506 is purified by the activated carbon 516 and then flows out through the gas outlet pipe 515, thereby achieving the purpose of purifying the gas; Step 7: The particles in the flue gas fall to the surface of the flip plate 520 under the action of their own gravity, and the drive motor 518 is started to drive the flip plate 520 to rotate downward, so that the particles retained on its surface fall to the bottom of the processing tank 506 under the action of their own gravity, thereby realizing the effective absorption and subsequent treatment of the flue gas generated when the CNC cutting machine cuts metal.

[0025] The working principle of this embodiment is as follows: when it is necessary to cut the metal guardrail, first place the required metal rod on the top of the leak plate 6, start the second forward and reverse motor 402, drive the bidirectional threaded rod 403 to rotate, and then drive the two clamping plates 404 to move towards each other until the metal rod is clamped and fixed, start the cutting head body 307, and then start the servo motor 204 first to drive the driving shaft 205 to rotate, and then drive the active gear 206 to rotate, so that the active gear 206 moves horizontally along the direction of the first tooth row 207, thereby driving the mounting frame 301 to move, and then the other moving rod 202 also moves along the matching limit rod 201. When the cutting head body 307 moves to a position parallel to the position where the metal rod needs to be cut, turn off the servo motor 204, start the stepper motor 304, drive the cutting head body 307 to move horizontally along the direction of the second tooth row 302, until the cutting head body 307 moves to the position where the metal rod needs to be cut, and the cutting head body 307 can cut the metal rod. At this time, start the first forward and reverse motor 204. The motor 503 drives the slide plate 505 to move along the inside of the slide groove 502 until the suction fan 509 moves to a position corresponding to the cutting head body 307, and the suction fan 509 is started, so that the smoke generated during the metal cutting process is adsorbed into the inside of the processing tank 506 under the action of negative pressure, and at the same time, the two semiconductor cooling sheets 510 are electrically connected to the external power supply, so that the inside of the processing tank 506 is in a low temperature state, so that the water vapor in the smoke entering the processing tank 506 is cooled and liquefied and retained on the surface of the multiple water tanks 507 After being purified by the adsorption plate 513, the flue gas enters the water storage tank 514 through the outlet pipe 512 for storage. The flue gas entering the treatment tank 506 is purified by the activated carbon 516 and then flows out through the outlet pipe 515. The particles in the flue gas fall to the surface of the flip plate 520 under the action of their own gravity. By rotating the flip plate 520, the particles retained on its surface fall to the bottom of the treatment tank 506 under the action of their own gravity, thereby realizing the effective absorption and subsequent treatment of the flue gas generated when the CNC cutting machine cuts metal.

[0026] In the present invention, when in use, during the process of processing and producing the metal guardrail, the required metal rod is first placed on the top of the leak plate 6. In order to ensure that the metal rod does not move during the cutting process, the second forward and reverse motor 402 is started to drive the bidirectional threaded rod 403 to rotate, thereby driving the two clamping plates 404 to move toward each other until the metal rod is clamped and fixed, and then the cutting head body 307 is started, and then the servo motor 204 is started to drive the driving shaft 205 to rotate, thereby driving the driving gear 206 to rotate, so that the driving gear 206 moves horizontally along the direction of the first tooth row 207, thereby driving the mounting frame 301 to move, and then the other moving rod 206 is moved horizontally. 02 also moves along the matching limit rod 201 to realize the horizontal movement of the cutting head body 307. When the cutting head body 307 moves to a position parallel to the position where the metal rod needs to be cut, the servo motor 204 is turned off, and then the stepper motor 304 is started to drive the rotating shaft 305 to rotate, thereby driving the driving gear 306 to rotate, so that the cutting head body 307 moves horizontally along the direction of the second tooth row 302 until the cutting head body 307 moves to the position where the metal rod needs to be cut. The cutting head body 307 can cut the metal rod. During the cutting process, extremely high temperature will be generated, and the high temperature will cause the metal to melt and evaporate rapidly. , and gas and smoke are generated, the first forward and reverse motor 503 is started, and the screw rod 504 is driven to rotate, thereby driving the slide plate 505 to move along the inside of the slide groove 502 until the suction fan 509 moves to a position corresponding to the cutting head body 307, and then the suction fan 509 can be started to absorb gas outward, so that the smoke generated in the metal cutting process is adsorbed into the inside of the processing tank 506 under the action of negative pressure, and at the same time, the two semiconductor refrigeration sheets 510 are electrically connected to the external power supply, so that the inside of the processing tank 506 is in a low temperature state, so that the water vapor in the smoke entering the processing tank 506 is pre-cooled and liquefied and retained on the surface of multiple water tanks 507 The flue gas flows along the water trough 507 downward to the inside of the water retaining plate 511, and finally enters the inside of the water storage tank 514 through the outlet pipe 512 for storage, wherein the harmful substances in the water can be absorbed by the setting of the adsorption plate 513, and the flue gas entering the treatment tank 506 is purified by the activated carbon 516 and then flows out through the outlet pipe 515 to achieve gas purification. When the particulate matter in the flue gas falls to the surface of the flip plate 520 under the action of its own gravity, the drive motor 518 is then started to drive the top of the flip plate 520 to rotate downward, so that the particulate matter retained on its surface falls to the bottom of the treatment tank 506 under the action of its own gravity.
