Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and specifically relates to a cooling cutting equipment for construction engineering machinery manufacturing. Background Art

[0002] In the field of construction engineering machinery manufacturing, high-temperature cutting is an indispensable process in scenarios such as metal processing and concrete treatment. With the improvement of engineering material strength (such as high-strength concrete and special alloy steel) and the tightening of environmental protection regulations, the cooling technology of traditional cutting equipment faces multiple challenges and urgently needs to be innovated to meet the requirements of efficiency, precision, and sustainable development. 90% of the existing equipment uses open-loop temperature control and cannot real-time sense the thermal field distribution in the cutting area (infrared temperature measurement response delay > 200 ms), resulting in a cooling medium waste rate exceeding 35%. Although it can reduce the tool wear rate (a 58% decrease compared to dry cutting), it requires an independent refrigeration unit (power ≥ 7.5 kW), increasing the equipment volume by 40%. It performs excellently in aluminum alloy processing, but when facing high-exothermic materials such as cast iron, the oil film rupture temperature (380 °C) is lower than the working condition requirements. Using solid-liquid phase change materials (such as paraffin / graphene composites) can absorb instantaneous high heat fluxes (heat flux ≥ 106 W / m 2 ), but the cold storage efficiency decay rate reaches 8% per month after recycling. The next-generation cooling equipment needs to break through key technologies such as medium heat transfer dynamics, multi-modal thermal management strategies, and waste heat recovery, which provides a clear technical evolution direction for the research and development of a new type of composite intelligent cooling system.

[0003] Most of the current equipment uses water cooling for temperature reduction, which not only consumes a large amount of water, but also the spraying depends on manual adjustment, resulting in low heat dissipation efficiency. Summary of the Invention

[0009] Preferably, the blade assembly includes a blade disc. A cutting groove is formed at the bottom of the blade disc. Air inlet holes are formed on the side surface of the blade disc. Air outlet holes are formed on one side of the blade disc away from the air inlet holes. The air inlet holes and the air outlet holes are communicated. The air inlet holes are arranged on the side close to the air guide housing. The side surface of the blade disc is rotationally connected to the side surface of the cutting bracket through a rotating shaft. The input end of the blade disc is fixedly connected to the output end of the sprocket transmission device. When the sprocket transmission device is started, the sprocket transmission device drives the blade disc to rotate. It rises or falls through the electric telescopic rod. When started, it drives the air to flow through the inside of the air guide housing, thereby driving the air to flow, and then through the inner wall of the air guide housing on the side surface of the blade disc. When the air passes through the air inlet holes to the air outlet holes, the air flow passing through the side surface of the blade disc is increased by the principle of the nozzle during the process of transferring from a small cross-section to a large cross-section. And the air guide housing wraps the side surfaces of the cutting bracket and the blade disc, so as to accurately air-cool the transmission position. And when the blade disc rotates, it continuously air-cools the side surface and combines with the water flow sprayed by the water inlet device for heat dissipation, increasing the heat dissipation efficiency while reducing the water consumption.

[0010] Preferably, the air inlet device includes an air inlet housing. A first motor is fixedly connected to the top of the air inlet housing. An upper fan is sleeved and fixedly connected to the driving shaft of the first motor. An upper toothed ring is fixedly connected to the bottom of the upper fan. A direction-changing gear is meshed with the bottom of the upper toothed ring. A fixed shaft is rotationally connected to the side surface of the direction-changing gear. A lower toothed ring is meshed with the bottom of the direction-changing gear. A lower fan is fixedly connected to the bottom of the lower toothed ring. The side surface of the air inlet housing is communicated with the side surface of the water inlet device. The bottom of the air inlet housing is fixedly connected to the top of the cutting base.

[0011] Preferably, the water inlet device includes a water inlet tank. A water inlet joint is communicated with the side surface of the water inlet tank. A U-shaped pipe is fixedly connected to the inner wall of the water inlet tank. A ventilation pipe is communicated with the side surface of the U-shaped pipe. An air outlet pipe is communicated with the side surface of the water inlet tank. A water delivery pipe is communicated with the bottom of the water inlet tank. A rotary joint is communicated with the bottom of the water delivery pipe. A water spray head is communicated with the bottom of the rotary joint.

The side surface of the ventilation pipe is communicated with the side surface of the air intake housing. The bottom of the water inlet tank is fixedly connected with the top of the cutting base. The side surface of the water inlet joint is communicated with one end of a water supply pipe. When the first motor is started, the drive shaft of the first motor rotates to drive the upper fan to rotate. The rotation of the upper fan drives the upper gear ring to rotate. The rotation of the upper gear ring drives the direction-changing gear to rotate. The rotation of the direction-changing gear drives the lower gear ring to rotate. The rotation of the lower gear ring drives the lower fan to rotate. The reverse rotation of the upper fan and the lower fan cancels the vibration influence caused by the torque during startup and rotation, and increases the shear of the air by the opposite rotation directions of the upper fan and the lower fan, thereby increasing the air flow. And when the air enters the air intake housing through the ventilation pipe, the water flow enters the inside of the water inlet joint through the water supply pipe and enters the inside of the water inlet tank through the loop of the U-shaped pipe, and reaches the inside of the rotary joint along the water delivery pipe, and is directly sprayed on the side surface of the blade disc through the water spray head, so as to accurately cool the cutting point position. And during the process of the water spray head spraying the water flow, the reaction force drives the rotary joint to rotate independently, thereby reducing the spraying dead angle and preventing incomplete cooling. At the same time, the air enters along and is sprayed on the cutting position along the air spray head, so that when the water flow passes through the surface of the blade disc, it is affected by the air flow at the same time, thereby increasing the heat dissipation speed. When the air passes through the side surface of the U-shaped pipe and enters the water inlet tank through the ventilation pipe, the air cools the water flow through the side surface of the U-shaped pipe, thereby dissipating the heat of the cooling water, so as to ensure that the water remains around room temperature during the circulation process, thereby ensuring the cooling quality. And the cross-sectional areas of the ventilation pipe and the air outlet pipe are different, so that the air intake volume of the ventilation pipe is much larger than the air flow of the air outlet pipe, thereby avoiding the influence of air backflow on the heat dissipation speed.

[0012] The present invention provides a temperature-reducing cutting device for construction engineering machinery manufacturing. It has the following beneficial effects:

[0013] 1. The cooling cutting equipment for construction engineering machinery manufacturing is provided with a water inlet. Cooling water is guided along the water inlet, and the cooling water mixed with iron filings during cutting enters the interior of the reservoir. Under the action of gravity, the water flow preferentially brings the iron filings into the interior of the sedimentation tank. Moreover, the density of metal powders such as iron filings is much greater than that of water, so that the iron filings sink naturally in the water, thus separating the iron filings from the water. Start the electric water pump. The start of the electric water pump drives the water flow to reach the interior of the arc-shaped guide plate through the water inlet head and is conveyed along the water delivery pipe. The upward design of the water inlet head avoids prolonging the time when blockage occurs due to iron filings accumulation, and reduces the probability of iron filings directly blocking the top of the water inlet head through the upward design. And the arc-shaped design of the arc-shaped guide plate is conducive to the automatic diversion of iron filings when sinking through the surface of the arc-shaped guide plate, thus avoiding accumulation.

[0014] 2. The cooling cutting equipment for construction engineering machinery manufacturing is provided with an arc-shaped limiting plate. When the steel is placed, the gravity of the steel drives the arc-shaped limiting plate to descend. The arc-shaped limiting plate rotates along the side surface of the rotating shaft, thus generating torsion on the torsion spring. When the steel contacts the surface of the support roller, under the torsion of the torsion spring, the arc-shaped limiting plate rotates back to its original position, thus restricting the top of the steel, and thus restricting the strip material. The torsion spring is used to limit the rotation angle of the arc-shaped limiting plate, so as to ensure that the top of the arc-shaped limiting plate is perpendicular to the side surface of the support frame. And during the rotation of the arc-shaped limiting plate along the torsion spring, the rotation of the arc-shaped limiting plate drives the driving gear to rotate. The rotation of the driving gear drives the rack to rise. The rising of the rack drives the limiting plate to rise, so that the limiting plate is disengaged from the side surface of the support roller, facilitating position adjustment, and thus restricting the strip material through multiple arc-shaped limiting plates.

[0015] 3. The cooling cutting equipment for construction engineering machinery manufacturing is provided with a sprocket drive device. Start the sprocket drive device. The sprocket drive device drives the blade disc to rotate, and rises or descends through the electric telescopic rod. Start, drive the air to flow through the interior of the air guide housing, and then drive the air to flow, and then pass through the inner wall of the air guide housing on the side of the blade disc. When the air passes from the air inlet hole to the air outlet hole, the air flow passing through the side of the blade disc is increased through the principle of the nozzle during the process of transferring from a small cross-section to a large cross-section. And the air guide housing wraps the side surfaces of the cutting support and the blade disc, thus accurately air-cooling the transmission position. And when the blade disc rotates, it continuously air-cools the side surface, and combines with the water flow sprayed by the water inlet device for heat dissipation, increasing the heat dissipation efficiency while reducing the water consumption.

[0016] 4. The cooling cutting equipment for construction engineering machinery manufacturing is provided with a first motor. The drive shaft of the first motor rotates to drive the upper fan to rotate. The rotation of the upper fan drives the upper toothed ring to rotate. The rotation of the upper toothed ring drives the direction-changing gear to rotate. The rotation of the direction-changing gear drives the lower toothed ring to rotate. The rotation of the lower toothed ring drives the lower fan to rotate. The reverse rotation of the upper fan and the lower fan cancels the vibration influence brought by the torque during startup and rotation, and increases the shear of the air by the opposite rotation directions of the upper fan and the lower fan, thereby increasing the air flow. And when the air enters the intake housing through the ventilation pipe, the water flow enters the inside of the water inlet joint through the water supply pipe and enters the inside of the water inlet tank through the loop of the U-shaped pipe, and reaches the inside of the rotary joint along the water delivery pipe, and is directly sprayed on the side of the blade disc through the water nozzle, so as to accurately cool the cutting point position.

[0017] 5. The cooling cutting equipment for construction engineering machinery manufacturing is provided with a water nozzle. During the process of the water nozzle spraying water flow, the reaction force drives the rotary joint to rotate independently, thereby reducing the spraying dead angle and preventing insufficient cooling. At the same time, the air enters along and jets to the cutting position along the air nozzle, so that when the water flow passes through the surface of the blade disc, it is affected by the air flow at the same time, thereby increasing the heat dissipation speed. When the air passes through the side of the U-shaped pipe and enters the water inlet tank through the ventilation pipe, the air cools the water flow through the side of the U-shaped pipe, thereby dissipating the heat of the cooling water, so as to ensure that the water remains around room temperature during the circulation process, thereby ensuring the cooling quality. And the cross-sectional areas of the ventilation pipe and the air outlet pipe are different, so that the air intake volume of the ventilation pipe is much larger than the air flow of the air outlet pipe, thereby avoiding the influence of air backflow on the heat dissipation speed.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1 - Figure 2 , the present invention provides a technical solution: a cooling cutting device for construction engineering machinery manufacturing, including an equipment base 1, a bottom plate bracket 2 is fixedly connected to the bottom of the equipment base 1, a filtering device 3 is fixedly connected to the inner wall of the equipment base 1, a supporting device 4 is rotatably connected to the inner wall of the filtering device 3, a fixed end of a two-way sliding table 5 is fixedly connected to the top of the equipment base 1, and a cutting device 6 is fixedly connected to the bottom of the moving end of the two-way sliding table 5. The cutting device 6 is arranged above the supporting device 4.

[0029] The equipment base 1 and the bottom plate bracket 2 support the equipment as a whole, the filter device 3 filters the cooling water and recycles it, the support device 4 fixes the steel bar to limit the jumping during cutting, thereby improving the cutting accuracy, and the two-way slide 5 drives the cutting device 6 to cut at different positions. The cutting device 6 improves the cooling efficiency by combining air cooling and water cooling, thereby ensuring that the heat dissipation speed can suppress the temperature during high-speed cutting, and the cutting device 6 ensures the heat dissipation quality by accurately spraying the cutting position, and cools the circulating water through the components corresponding to the air intake, thereby ensuring the cooling quality and preventing the cooling speed from decreasing due to too many cycles.

[0030] The filtering device 3 includes a water inlet 301, the bottom of the water inlet 301 is connected to a water reservoir 302, sedimentation tanks 303 are provided on both sides of the bottom of the water reservoir 302, the side of the water reservoir 302 is connected to the water inlet of an electric water pump 304, an arc-shaped guide plate 305 is fixedly connected to the top of the inner wall of the sedimentation tank 303, the top of the arc-shaped guide plate 305 is connected to the water inlet head 306, the water outlet end of the electric water pump 304 is connected to a water supply pipe 307, the side of the water inlet 301 is fixedly connected to the inner wall side of the base plate bracket 2, and the end of the water supply pipe 307 away from the electric water pump 304 is connected to the side of the cutting device 6.

[0031] The cooling water is guided along the water inlet 301, and the cooling water mixed with the iron filings during cutting enters the interior of the water reservoir 302. Under the action of gravity, the water flow preferentially brings the iron filings into the interior of the sedimentation tank 303, and the density of metal powders such as iron filings is much greater than that of water, so that the iron filings naturally sink in the water, thereby separating the iron filings and water, and starting the electric water pump 304. The electric water pump 304 starts to drive the water flow through the water inlet head 306 to the interior of the arc guide plate 305 and is transported along the water supply pipe 307. The upward design of the water inlet head 306 avoids extending the time of blockage caused by the accumulation of iron filings, and the upward design reduces the probability of iron filings directly blocking the top of the water inlet head 306, and the arc design of the arc guide plate 305 is conducive to automatic diversion of iron filings through the surface of the arc guide plate 305 when they sink, thereby avoiding accumulation.

[0032] See also Figure 1 - Figure 4, the present invention provides a technical solution: The supporting device 4 includes a supporting roller 401. A moving ring 402 is sleeved and slidably connected to the side surface of the supporting roller 401. A supporting frame 403 is fixedly connected to the side surface of the moving ring 402. A rotating shaft 404 is rotatably connected to the side surface of the supporting frame 403. An arc-shaped limiting plate 405 is sleeved and rotatably connected to the side surface of the rotating shaft 404. A limiting strip 406 is fixedly connected to the top of the arc-shaped limiting plate 405. A torsion spring 407 is sleeved and slidably connected to the side surface of the rotating shaft 404. A braking component 408 is fixedly connected to the side surface of the arc-shaped limiting plate 405. One end of the torsion spring 407 is fixedly connected to the bottom of the arc-shaped limiting plate 405, and the end of the torsion spring 407 away from the arc-shaped limiting plate 405 is fixedly connected to the side surface of the supporting frame 403. The side surface of the supporting roller 401 is rotatably connected to the inner side surface of the water inlet 301.

[0033] The braking component 408 includes a driving gear 4081. A rack 4082 is engaged with the side surface of the driving gear 4081. A limiting plate 4083 is fixedly connected to the bottom of the rack 4082. The side surface of the driving gear 4081 is fixedly connected to the side surface of the arc-shaped limiting plate 405. The limiting plate 4083 passes through the side surface of the moving ring 402 and is slidably connected to the moving ring 402. A triangular rack adapted to the limiting plate 4083 is provided on the side surface of the supporting roller 401.

[0034] When the steel is placed, the gravity of the steel drives the arc-shaped limiting plate 405 to descend. The arc-shaped limiting plate 405 rotates along the side surface of the rotating shaft 404, thereby generating a torsion force on the torsion spring 407. When the steel contacts the surface of the supporting roller 401, under the action of the torsion force of the torsion spring 407, the arc-shaped limiting plate 405 rotates back to its original position, thereby restricting the top of the steel, and thus restricting the strip-shaped material. The torsion spring 407 is used to limit the rotation angle of the arc-shaped limiting plate 405, thereby ensuring that the top of the arc-shaped limiting plate 405 is perpendicular to the side surface of the supporting frame 403. And during the rotation of the arc-shaped limiting plate 405 along the torsion spring 407, the rotation of the arc-shaped limiting plate 405 drives the driving gear 4081 to rotate. The rotation of the driving gear 4081 drives the rack 4082 to rise. The rising of the rack 4082 drives the limiting plate 4083 to rise, so that the limiting plate 4083 is disengaged from the side surface of the supporting roller 401, facilitating position adjustment. Thus, the strip-shaped material is restricted by multiple arc-shaped limiting plates 405. When the arc-shaped limiting plate 405 rotates back to its original position, the limiting plate 4083 is driven along the same path, so that the limiting plate 4083 is re-engaged with the side surface of the supporting roller 401, thereby restricting the side surface of the strip-shaped material, ensuring stability during cutting.

On the side of the cutting bracket 605, a sprocket transmission device 606 is fixedly connected. The output end of the sprocket transmission device 606 is fixedly connected to a blade assembly 607. The top of the cutting base 603 communicates with the air outlet of an air intake device 608. On the top of the cutting base 603, on both sides of the air intake device 608, a water inlet device 609 is fixedly connected. The fixed end of the electric telescopic rod 601 is fixedly connected to the bottom of the moving end of the two-way slide 5.

[0036] The blade assembly 607 includes a blade disc 6071. A cutting groove 6072 is formed at the bottom of the blade disc 6071. An air inlet hole 6073 is formed on the side of the blade disc 6071. An air outlet hole 6074 is formed on the side of the blade disc 6071 away from the air inlet hole 6073. The air inlet hole 6073 and the air outlet hole 6074 are communicated.

[0037] Start the sprocket transmission device 606. The sprocket transmission device 606 drives the blade disc 6071 to rotate. Raise or lower through the electric telescopic rod 601. Start the air intake device 608. The air intake device 608 drives the air to flow through the inside of the air guide housing 604, thereby driving the air to flow and pass through the inner wall of the air guide housing 604 on the side of the blade disc 6071. When the air passes through the air inlet hole 6073 to reach the air outlet hole 6074, the air flow rate passing through the side of the blade disc 6071 is increased by the principle of a nozzle during the process of transferring from a small cross-section to a large cross-section. And the air guide housing 604 wraps the sides of the cutting bracket 605 and the blade disc 6071, thereby accurately air-cooling the transmission position. And when the blade disc 6071 rotates, it continuously air-cools the side and combines with the water flow sprayed by the water inlet device 609 for heat dissipation, increasing the heat dissipation efficiency while reducing the water consumption.

[0040] Start the first motor 6082. The rotation of the drive shaft of the first motor 6082 drives the upper fan 6083 to rotate. The rotation of the upper fan 6083 drives the upper gear ring 6084 to rotate. The rotation of the upper gear ring 6084 drives the direction-changing gear 6085 to rotate. The rotation of the direction-changing gear 6085 drives the lower gear ring 6087 to rotate. The rotation of the lower gear ring 6087 drives the lower fan 6088 to rotate. The reverse rotation of the upper fan 6083 and the lower fan 6088 cancels the vibration impact caused by the torque during startup and rotation, and the opposite rotation directions of the upper fan 6083 and the lower fan 6088 increase the shear of the air, thereby increasing the air flow rate. And when the air enters the intake housing 6081 through the ventilation pipe 6094, the water flow passes through the water supply pipe 307 into the interior of the water inlet joint 6092 and enters the interior of the water inlet tank 6091 through the loop of the U-shaped pipe 6093, and reaches the interior of the rotary joint 6097 along the water delivery pipe 6096, and is directly sprayed on the side of the blade disc 6071 through the water spray head 6098, so as to accurately cool the cutting point position. And during the process of the water spray head 6098 spraying the water flow, the reaction force drives the rotary joint 6097 to rotate independently, thereby reducing the spraying dead angle and preventing incomplete cooling. At the same time, the air enters along 3095 and jets at the cutting position along the air spray head 6099, so that when the water flow passes through the surface of the blade disc 6071, it is affected by the air flow at the same time, thereby increasing the heat dissipation speed. When the air passes through the side of the U-shaped pipe 6093 and passes through the ventilation pipe 6094 into the water inlet tank 6091, the air cools the water flow through the side of the U-shaped pipe 6093, thereby dissipating the heat of the cooling water, so as to ensure that the water remains around room temperature during the circulation process, so as to ensure the cooling quality. And the cross-sectional areas of the ventilation pipe 6094 and the air outlet pipe 6095 are different, so that the air intake volume of the ventilation pipe 6094 is much larger than the air flow rate of the air outlet pipe 6095, thereby avoiding the influence of air backflow on the heat dissipation speed.
