[0002] Pipes are long, hollow-section materials widely used in various engineering fields, including construction, machinery, chemicals, petroleum, natural gas, and water supply and drainage. Quenching is a heat treatment process that involves heating the pipe to a critical temperature, holding the temperature for a period of time to fully or partially austenitize it, and then cooling it at a rate greater than the critical cooling rate.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0022] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0023] like Figure 1-Figure 5 As shown, a pipe quenching device includes: a quenching box 1, a placement box 101 arranged on one side of the interior of the quenching box 1, two arc-shaped support blocks 102 installed at the bottom end of the placement box 101, an open groove 103 opened at the bottom of the placement box 101, and a cooling component arranged at the top and bottom of the placement box 101, the cooling component including: a cooling box 2, a fixing frame 201, a cooling fan 202, a through port 203, an electric push rod 204 and a temperature sensor a205, and a quenching component arranged on one side of the interior of the quenching box 1, the quenching component including: a water storage tank 4, a water pump 401, a delivery pipe 402, a diversion pipe 403 and a sprinkler head 404.

[0024] Among them, a cooling box 2 is installed on one side of the top of the quenching box 1, and a fixing frame 201 is installed inside the cooling box 2 and the quenching box 1. A plurality of cooling fans 202 are installed on the fixing frame 201. Through openings 203 are opened on both sides of the top of the fixing frame 201, and electric push rods 204 are installed on both sides of the inside of the cooling box 2. The electric push rods 204 are located inside the through openings 203, and a temperature sensor a205 is installed at the bottom of the electric push rods 204.

[0025] After heating the pipe, the door of the cooling box 2 is opened, and the pipe is clamped with a tool and placed in the placement box 101. The pipe is suspended and supported by two arc-shaped support blocks 102. The arc-shaped support blocks 102 can prevent the pipe from rolling and have a good limiting effect. After the pipe is placed, the door of the cooling box 2 is closed and multiple cooling fans 202 are started. Since multiple cooling fans 202 are all arranged in the direction of the placement box 101, they can blow air to the top and bottom of the placement box 101, thereby cooling the pipe inside the placement box 101, and starting the electric push rod 204 to push the temperature sensor a205 downward to the top of the pipe. The temperature of the pipe is detected by the temperature sensor a205. When the temperature of the pipe meets the quenching requirements, the multiple cooling fans 202 can be turned off to facilitate rapid cooling of the pipe and avoid high pipe temperature. Direct water cooling and quenching will cause high internal stress in the pipe and cause quenching cracks, providing protection for the pipe and improving the working efficiency of pipe quenching.

[0026] When blowing air toward the bottom of the placement box 101 , the provision of the open slots 103 can ensure that the blowing air cools the bottom of the pipe.

[0027] Among them, a forward and reverse motor 3 is installed on one side of the outer end of the quenching box 1, and a threaded screw 301 is connected to the output end of the forward and reverse motor 3, and the threaded screw 301 is rotatably connected to the other end of the quenching box 1 through a bearing, and a threaded sleeve 302 is threadedly connected to the threaded screw 301. Support rods 303 are installed on both sides of the outer end of the placement box 101, and movable grooves 304 are opened on both sides of the inner wall of the quenching box 1, and one of the support rods 303 passes through the movable groove 304 and is connected to the threaded sleeve 302.

[0028] When the temperature of the pipe drops to a temperature suitable for quenching, the forward and reverse motor 3 is started to drive the threaded screw 301 to rotate forward, and the threaded sleeve 302 and the threaded screw 301 rotate in a threaded manner, that is, the threaded screw 301 can drive the threaded sleeve 302 to move to the right, and the threaded sleeve 302 will drive the support rod 303 to move inside the movable groove 304, so that the support rod 303 drives the placement box 101 to move to the right to the other side of the quenching box 1, so that the placement box 101 is located at the bottom of multiple water spray heads 404. At this time, multiple water spray heads 404 are all facing the pipes inside the placement box 101, which is convenient for quenching the pipes.

[0029] Among them, fixed plates 305 are installed on both sides of the outer end of the quenching box 1, and a sliding rod 306 is installed between the two fixed plates 305. A sliding sleeve 307 is slidably connected to the sliding rod 306, and another support rod 303 passes through the movable groove 304 and is connected to the sliding sleeve 307. When the wire sleeve 302 drives the support rod 303 and the placement box 101 to move, the other support rod 303 will also be forced to move inside the movable groove 304 on the other side, that is, the other support rod 303 drives the sliding sleeve 307 to slide on the sliding rod 306, and moves synchronously to ensure that the placement box 101 runs stably and is placed stably.

[0030] Among them, a water tank 4 is installed on one side of the cooling box 2, and a water pump 401 is installed at the bottom end of the water tank 4. The bottom of the water pump 401 is connected to a delivery pipe 402, and a diversion pipe 403 is installed at the bottom of the delivery pipe 402. A plurality of water spray heads 404 are installed at the bottom of the diversion pipe 403. When the placement box 101 moves to the bottom of the multiple water spray heads 404, the water pump 401 is started to work, and the water pump 401 draws the water in the water tank 4 into the delivery pipe 402, and transports it to the diversion pipe 403 through the delivery pipe 402. The water is discharged into the multiple water spray heads 404 through the diversion pipe 403, that is, the multiple water spray heads 404 spray toward the pipes inside the placement box 101 to cool and quench the pipes. The good fluidity of the water spray quenching ensures that the water temperature remains low, which can speed up the quenching of the pipes.

[0031] Among them, a filter plate 5 is installed on one side of the inside of the quenching box 1, a collecting box 501 is provided on the outside of the quenching box 1, a collecting chamber 502 is provided on one side of the collecting box 501, a water pump 503 is installed on the outside of the quenching box 1, a water pump a is installed between the water pump 503 and the quenching box 1, a drain pipe is installed between the water pump 503 and the collecting chamber 502, a reflux pump 504 is installed on the top of the collecting box 501, a water pump b is installed between the reflux pump 504 and the collecting chamber 502, and a reflux pipe is installed between the reflux pump 504 and the water storage tank 4.

[0032] After the pipes inside the placement box 101 are sprayed with water for cooling and quenching, the water inside the placement box 101 is discharged from the open groove 103 and falls onto the filter plate 5. The impurities generated by quenching in the water can be filtered out through the filter plate 5, and the filtered water falls to the bottom end of the quenching box 1. The water pump 503 is started to generate negative pressure suction in the water pumping pipe a to pump out the filtered water, and the water is transported to the drain pipe through the water pump 503 and discharged into the collection chamber 502, and then the water is recycled and reused. When the water is stored in the collection chamber 502, the temperature of the water will slowly decrease, and then the reflux pump 504 is started to generate negative pressure suction in the water pumping pipe b to pump out the cooled water in the collection chamber 502, and the water is transported to the reflux pipe through the reflux pump 504 and discharged into the water storage tank 4 for reuse, saving water and reducing the production cost of pipe quenching.

[0033] Among them, a plurality of heat dissipation fins 505 are installed on the outer wall of the collection chamber 502, a heat dissipation port 506 is opened on the outside of the collection box 501, a heat dissipation fan 507 is installed on the top of the collection box 501, and the heat dissipation fan 507 is located on the top of the plurality of heat dissipation fins 505, and a temperature sensor b508 is installed on one side of the interior of the collection chamber 502. When the filtered water is discharged into the collection chamber 502 and placed, due to the high temperature of the water, the heat is dissipated to the outer wall of the collection chamber 502 through the plurality of heat dissipation fins 505, so that the water collected in the collection chamber 502 is quickly cooled, and the heat can be discharged from the collection box 501 through the heat dissipation port 506 and taken away by the air flow, and the heat dissipation fan 507 is started to blow air to the plurality of heat dissipation fins 505, so that the heat is quickly dissipated, and the water temperature is detected by the temperature sensor b508 to know the water temperature. After the water temperature drops, it is pumped into the water storage tank 4 for reuse.

[0034] Among them, when the quenching box 1 is in use, a control box is fixedly installed on the outside of the quenching box 1, a display screen and multiple control buttons are installed on the outside of the control box, and a power cord is provided at the bottom of the control box, and the cooling fan 202, the electric push rod 204, the temperature sensor a205, the forward and reverse motor 3, the water pump 401, the water pump 503, the reflux pump 504, the heat dissipation fan 507 and the temperature sensor b508 are connected to the control box through wires. The power cord is two meters long and a plug is installed at the other end of the power cord. The plug can be inserted into the socket in the workshop to turn on the power, so that the control box, the cooling fan 202, the electric push rod 204, the temperature sensor a205, the forward and reverse motor 3, the water pump 401, the water pump 503, the reflux pump 504, the heat dissipation fan 507 and the temperature sensor b508 are connected to the control box through wires. The temperature sensor a205, the forward and reverse motor 3, the water pump 401, the water pump 503, the reflux pump 504, the cooling fan 507 and the temperature sensor b508 are powered on and used normally. The cooling fan 202, the electric push rod 204, the temperature sensor a205, the forward and reverse motor 3, the water pump 401, the water pump 503, the reflux pump 504, the cooling fan 507 and the temperature sensor b508 can be started and shut down by the control chassis. The control procedures involved in the present invention can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the present invention.

[0035] Among them, the model of temperature sensor a205 and temperature sensor b508 can be WZP-291, and its working principle is: temperature sensor a205 and temperature sensor b508 are generally composed of three parts: temperature sensitive element, conversion element and temperature conversion circuit. The function of temperature sensitive element is to convert the sensed temperature signal into a quantity that is easy to measure and has a certain relationship with temperature. The function of conversion element is to convert the physical quantity output by temperature sensitive element into electrical quantity output. The function of conversion circuit is to convert the electrical quantity output by conversion element into electrical quantity that is easy to measure, such as voltage, current, frequency, etc. Temperature sensor a205 and temperature sensor b508 are mature conventional technologies in this technical field, and this scheme does not make any improvements to the circuit or program of temperature sensor a205 and temperature sensor b508. The circuit and signal connection method between temperature sensor a205 and temperature sensor b508 and control chassis also belongs to public conventional technology, so the circuit and signal connection relationship will not be elaborated.

[0036] The temperatures detected by temperature sensor a205 and temperature sensor b508 can be transmitted to the display screen of the control chassis through electrical signals for viewing by staff.

[0037] Working principle:

[0038] After heating the pipe, the door of the cooling box 2 is opened, and the pipe is clamped with a tool and placed in the placement box 101. The pipe is suspended and supported by two arc-shaped support blocks 102. The arc-shaped support blocks 102 can prevent the pipe from rolling and have a good limiting effect. After the pipe is placed, the door of the cooling box 2 is closed and multiple cooling fans 202 are started. Since multiple cooling fans 202 are all arranged in the direction of the placement box 101, they can blow air to the top and bottom of the placement box 101, thereby cooling the pipe inside the placement box 101, and starting the electric push rod 204 to push the temperature sensor a205 downward to the top of the pipe. The temperature of the pipe is detected by the temperature sensor a205. When the temperature of the pipe meets the quenching requirements, the multiple cooling fans 202 can be turned off, which is convenient for quickly cooling the pipe and avoiding high pipe temperature. Direct water cooling and quenching will cause high internal stress in the pipe and cause quenching cracks, providing pipe protection for the pipe and improving the working efficiency of pipe quenching.

[0039] When the temperature of the pipe is reduced to a temperature suitable for quenching, the forward and reverse motor 3 is started to drive the threaded screw 301 to rotate forward, and the threaded sleeve 302 and the threaded screw 301 are threadedly rotated, that is, the threaded screw 301 can drive the threaded sleeve 302 to move to the right, and the threaded sleeve 302 will drive the support rod 303 to move inside the moving groove 304, so that the support rod 303 drives the placement box 101 to move to the right to the other side of the quenching box 1, so that the placement box 101 is located at the bottom of the multiple water spray heads 404. At this time, the multiple water spray heads 404 are all directed toward the pipes inside the placement box 101. The water pump 401 is started to pump the water in the water tank 4 out to the delivery pipe 402, and the water is delivered to the diversion pipe 403 through the delivery pipe 402. The water is discharged into multiple water spray heads 404 through the diversion pipe 403. That is, multiple water spray heads 404 spray toward the pipes inside the placement box 101 to cool and quench the pipes. The good fluidity of the water spray quenching ensures that the water temperature remains low, which can speed up the quenching of the pipes.

[0040] After the pipes inside the placement box 101 are sprayed with water for cooling and quenching, the water inside the placement box 101 is discharged from the open groove 103 and falls onto the filter plate 5. The impurities generated by quenching in the water can be filtered out through the filter plate 5, and the filtered water falls to the bottom end of the quenching box 1. The water pump 503 is started to generate negative pressure suction in the water pumping pipe a to pump out the filtered water, and the water is transported to the drain pipe through the water pump 503 and discharged into the collection chamber 502, and then the water is recycled and reused. When the water is stored in the collection chamber 502, the temperature of the water will slowly decrease, and then the reflux pump 504 is started to generate negative pressure suction in the water pumping pipe b to pump out the cooled water in the collection chamber 502, and the water is transported to the reflux pipe through the reflux pump 504 and discharged into the water storage tank 4 for reuse, saving water and reducing the production cost of pipe quenching.
