Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, specifically a cooling device for cutting stainless steel pipes. Background Technology

[0002] Stainless steel pipes are pipes made from stainless steel, possessing excellent corrosion resistance. This allows them to be used in various harsh environments, resisting rust and corrosion, thus extending their service life. They also have good strength and toughness, capable of withstanding significant pressure and external impacts, making them suitable for various systems requiring fluid transport, such as building water supply and drainage, chemical liquid transportation, and food and beverage processing. Furthermore, the smooth inner wall of stainless steel pipes results in low fluid resistance, improving transport efficiency. Their aesthetically pleasing and hygienic appearance also meets the needs of industries with high hygiene standards. During production, stainless steel pipes require the use of cutting equipment to cut them.

[0003] Chinese patent CN212329814U discloses a stainless steel pipe cutting device. This device can fix and clamp the stainless steel pipe between the arc grooves, preventing the pipe from shaking and shifting during cutting, thus improving the stability of the cutting and helping to maintain a good working environment. Furthermore, the device uses an induced draft fan to introduce the cutting waste into the chip collection box, which also helps to maintain a good working environment. The cut stainless steel pipe slides down the mesh plate for easy collection.

[0004] However, during the cutting process, due to the high-speed rotation of the cutting wheel, the generated debris will fly around. It is difficult to remove all the debris by relying solely on the suction of the blower. Some debris will still fall around the device, increasing the cleaning work for the operators. Furthermore, prolonged high temperatures can damage the cutting wheel and reduce its service life. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for cutting stainless steel pipes, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A cooling device for cutting stainless steel pipes includes a water tank. A first U-shaped frame is mounted on the upper surface of the water tank. A cover is mounted below the first U-shaped frame via a lifting mechanism. A motor is mounted on the outer surface of the cover, and the output shaft of the motor passes through the cover and is fitted with a cutting grinding wheel. Multiple nozzles are mounted on the outer surface of the cover via a spraying mechanism, and the nozzles are distributed along an arc-shaped trajectory. Fixing mechanisms for securing the stainless steel pipes are provided on both the front and rear sides of the upper surface of the water tank.

[0008] Therefore, by setting up a spraying mechanism, coolant can be continuously sprayed onto the cutting area during the cutting process to cool it down. This prevents the cutting wheel from experiencing a reduced lifespan due to continuous high temperatures, and also prevents pipe deformation caused by high temperatures, ensuring the smoothness of the pipe cut. Furthermore, the sprayed coolant can suppress debris splashing, thereby reducing the probability of debris falling around the device and alleviating the burden of cleaning work for operators.

[0009] Furthermore, the lifting mechanism includes a hydraulic cylinder installed on the top of the first U-shaped frame. The end of the hydraulic cylinder extends through to the bottom of the first U-shaped frame and is fitted with a horizontal plate. Connecting rods are installed on both sides of the lower surface of the horizontal plate, and the ends of the connecting rods are connected to the cover.

[0010] Furthermore, the spraying mechanism includes a water pump installed on the outer surface of the water tank, with the pump's input end communicating with the interior of the water tank. The pump's output end is connected to a liquid outlet pipe, the end of which extends vertically through to the bottom of the first U-shaped frame and is connected to a spiral flexible hose. An arc-shaped pipe is installed on the outer surface of the shroud, with multiple nozzles distributed at equal angles on the surface of the arc-shaped pipe, and the end of the spiral flexible hose is connected to the arc-shaped pipe.

[0011] Furthermore, the fixing mechanism includes a second U-shaped frame installed on the upper surface of the water tank, a cylinder installed on the top of the second U-shaped frame, an upper clamping plate installed at the end of the cylinder's telescopic end, and a lower clamping plate installed on the upper surface of the water tank below the upper clamping plate.

[0012] Furthermore, grooves are provided on both inner walls of the first U-shaped frame, and guide plates are provided at the bottom of the grooves.

[0013] Furthermore, the inside of the water tank is equipped with a filter plate, and hooks are installed at the four corners of the upper surface of the filter plate.

[0014] Furthermore, guide posts are installed on both sides of the upper surface of the horizontal plate, and the ends of the guide posts slide through to the top of the first U-shaped frame.

[0015] Furthermore, the upper clamping plate is connected to the telescopic end of the cylinder by bolts, and the lower clamping plate is installed on the upper surface of the water tank by bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. This utility model, through the setting of the spraying mechanism, can continuously spray coolant onto the cutting area during the cutting process to cool it down, thereby avoiding the reduction of the life of the cutting wheel due to continuous high temperature, and also avoiding the deformation of the pipe due to high temperature, ensuring the smoothness of the pipe cut. In addition, the sprayed coolant can also suppress the splashing of debris, thereby reducing the probability of debris falling around the device and reducing the burden of cleaning work for operators.

[0018] 2. By setting up grooves and guide plates, this utility model can block splashed coolant and allow it to fall back into the water tank along the surface of the guide plates for recycling, thereby avoiding any impact on the surrounding environment. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4This utility model provides a cooling device for cutting stainless steel pipes, including a water tank 100. A first U-shaped frame 101 is installed on the upper surface of the water tank 100. A cover 102 is installed below the first U-shaped frame 101 via a lifting mechanism 200. A motor 105 is installed on the outer surface of the cover 102, and the output shaft of the motor 105 passes through the cover 102 and is fitted with a cutting grinding wheel 103. Multiple nozzles 104 are installed on the outer surface of the cover 102 via a spraying mechanism 300, and the multiple nozzles 104 are distributed along an arc-shaped trajectory. Fixing mechanisms 400 for fixing stainless steel pipes are provided on both the front and rear sides of the upper surface of the water tank 100.

[0026] In use, the pipe is fixed below the cutting wheel 103 by two sets of fixing mechanisms 400. The motor 105 is started to drive the cutting wheel 103 to rotate. The lifting mechanism 200 drives the cutting wheel 103 to descend and cut the pipe. During the cutting process, the spraying mechanism 300 delivers coolant from the water tank 100 to the nozzle 104, thereby continuously spraying coolant on the cut area to cool it down. This prevents the cutting wheel 103 from having a reduced lifespan due to continuous high temperature, and also prevents the pipe from deforming due to high temperature, ensuring the smoothness of the pipe cut. In addition, the sprayed coolant can also suppress the splashing of debris, thereby reducing the probability of debris falling around the device and reducing the burden of cleaning work for operators.

[0027] Preferably, the lifting mechanism 200 includes a hydraulic cylinder 201 installed on the top of the first U-shaped frame 101. The end of the extension end of the hydraulic cylinder 201 extends through to the bottom of the first U-shaped frame 101 and is fitted with a horizontal plate 202. Connecting rods 203 are installed on both sides of the lower surface of the horizontal plate 202, and the ends of the connecting rods 203 are connected to the cover 102.

[0028] When the hydraulic cylinder 201 is activated, it can drive the horizontal plate 202 to rise and fall, and through the connecting rod 203, it can drive the cutting wheel 103 to rise and fall.

[0029] Preferably, the spraying mechanism 300 includes a water pump 301 mounted on the outer surface of the water tank 100, with the input end of the water pump 301 communicating with the interior of the water tank 100. The output end of the water pump 301 is connected to a liquid outlet pipe 302, the end of which extends vertically through to the bottom of the first U-shaped frame 101 and is connected to a spiral flexible hose 303. An arc-shaped pipe 304 is mounted on the outer surface of the cover 102, and multiple nozzles 104 are distributed at equal angles on the surface of the arc-shaped pipe 304, with the end of the spiral flexible hose 303 connected to the arc-shaped pipe 304.

[0030] When the water pump 301 is started, the coolant in the water tank 100 can be drawn out and transported to the spiral hose 303 through the outlet pipe 302. After the coolant enters the arc-shaped pipe 304, it can be sprayed out evenly from multiple nozzles 104 to achieve the purpose of cooling. Furthermore, due to the expansion and contraction capability of the spiral hose 303, it can adapt to the height changes of the cutting wheel 103.

[0031] Preferably, the fixing mechanism 400 includes a second U-shaped frame 401 installed on the upper surface of the water tank 100, a cylinder 402 installed on the top of the second U-shaped frame 401, an upper clamping plate 403 installed at the end of the telescopic end of the cylinder 402, and a lower clamping plate 404 installed on the upper surface of the water tank 100 and below the upper clamping plate 403.

[0032] After the pipe is placed inside the lower clamping plate 404, the cylinder 402 is activated. The cylinder 402 drives the upper clamping plate 403 to descend and press against the outer surface of the pipe, thereby achieving the purpose of clamping and fixing. Since the two sets of fixing mechanisms 400 can fix both sides of the pipe cutting part respectively, the stability of the pipe during the cutting process can be guaranteed and displacement can be avoided.

[0033] Preferably, grooves 500 are provided on both inner walls of the first U-shaped frame 101, and a guide plate 501 is provided at the bottom of the grooves 500.

[0034] By setting the groove 500 and the guide plate 501, the splashed coolant can be blocked and fall back into the water tank 100 along the surface of the guide plate 501 for recycling, thereby avoiding any impact on the surrounding environment.

[0035] Preferably, the interior of the water tank 100 is provided with a filter plate 600, and hooks 601 are installed at the four corners of the upper surface of the filter plate 600.

[0036] The filter plate 600 filters the cut coolant, trapping debris on its surface and preventing the nozzle 104 from becoming clogged during coolant circulation. Furthermore, the filter plate 600 is mounted inside the water tank 100 via hooks 601, allowing for easy removal and cleaning of the trapped debris.

[0037] Preferably, guide posts 700 are installed on both sides of the upper surface of the horizontal plate 202, and the ends of the guide posts 700 slide through to the top of the first U-shaped frame 101.

[0038] Since the cutting wheel 103 generates a certain lateral force during the cutting process, the guide post 700 can effectively resist the lateral force, ensure the stability of the cutting wheel 103 during the cutting process, and prevent the lateral force from being transmitted to the hydraulic cylinder 201, thus affecting its service life.

[0039] Preferably, the upper clamping plate 403 is connected to the telescopic end of the cylinder 402 by bolts, and the lower clamping plate 404 is installed on the upper surface of the water tank 100 by bolts.

[0040] With its detachable installation method, the upper clamp 403 and lower clamp 404 of the appropriate model can be replaced according to the size of the pipe to be cut, thus making it suitable for cutting pipes of different sizes.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
