Description

Technical Field

[0001] The present invention relates to the technical field of barrel rolling heat treatment, and more particularly to an online barrel rolling heat treatment device and method. Background Art

[0002] Large cylindrical forgings are key components in nuclear power, petrochemical, aerospace, wind power, and military equipment, generating significant market demand. While large cylindrical forgings have been domestically produced, achieving short-process precision manufacturing remains challenging due to the constraints of traditional design methods and manufacturing processes. Traditional cylindrical forging production processes involve complex, multi-fire forging and repeated offline heat treatment. Short-process precision manufacturing technology integrates casting, forming, and even heat treatment, shortening the process and achieving integrated manufacturing. This reduces equipment investment, simplifies production processes, shortens production cycles, and significantly lowers product costs. Product quality rivals that of traditional processes, and even allows for easier online control and optimization. Furthermore, with the goal of intelligent integration, the highly automated short-process integrated precision manufacturing allows for online control of process parameters, significantly impacting the development of previously difficult-to-produce materials and new materials with specialized properties. Furthermore, developing energy-saving, material-saving, and green forming and modification technologies will improve production efficiency and enable automated production.

[0003] To achieve the above-mentioned short-process integrated precision manufacturing, online heat treatment is a very important and necessary technical link. Online heat treatment is a heat treatment that directly accelerates cooling by using the waste heat of rolling. Usually, after the barrel is rolled, online heat treatment is carried out using the heat and deformation microstructure generated by the barrel rolling.

[0004] In a polygonal drum type oblique rolling ball mill steel ball quenching device with patent number CN108330270A, it is used for diameter The quenching heat treatment process of the obliquely rolled ball mill steel balls is rapidly cooled from 800℃ to 900℃ to 100℃ to 300℃. The quenching drum of the device is a polygonal cylinder composed of multiple cylindrical flat plates. There are cylinder partitions and steel ball lifting plates on the inner side of the cylinder flat plate. The cylinder partitions are arranged obliquely, and spiral grooves are formed between the cylinder partitions. The steel balls enter the quenching device through the ball inlet channel. In the polygonal cylinder, they are sequentially lifted by the inner corners of the polygon and then rolled and quenched in the spiral groove. At the end of the spiral groove, the steel balls are lifted to a certain height by the steel ball lifting plate and freely fall into the ball outlet channel to be discharged. There are waist-shaped through holes on the cylinder flat plate for the flow of quenching medium inside and outside the cylinder, realizing heat exchange inside and outside the cylinder, and finally completing quenching. Although this patent discloses a quenching heat treatment device, the product type and specifications, quenching process, quenching device principle and structure are completely different.

[0005] In actual use, different materials, different sizes, and different performance requirements all require different cooling rates. Therefore, when performing online heat treatment, due to the different specifications of the rolled products, it is necessary to adjust the specifications of the barrel products accordingly to achieve the online heat treatment process. In view of this, the patent application mainly solves the following problems: During the online heat treatment after the barrel is rolled, all data needs to be constantly adjusted manually. This constant adjustment makes the process steps inconvenient to handle, which is not conducive to rapid processing, thereby affecting the efficiency of the online heat treatment.

[0012] An operating method of a barrel rolling online heat treatment device, the specific steps are as follows:

[0013] Step 1: Input the cooling speed and product size characteristic data of each model of barrel through the operation panel and store them in the storage host. In addition, whether oil cooling or water cooling is required for barrels of different materials is recorded and stored in the storage host. The corresponding cooling water spray volume, inner ring water spray time, and outer surface water spray time are also recorded. In this way, a database is formed. Then, when cooling of a specific model of barrel product is required, the data of this model, the corresponding cooling water spray volume, and the outer ring cooling time can be exported.

[0014] Step 2: When adjusting the size, you can click on the operation panel according to the size data of the cylinder recorded in the storage host, so as to adjust the inner and outer diameters of the cylinder product within the range. Select and click. When the material that needs water cooling is selected and the size is the corresponding size of the barrel product, the drive motor can be started. The drive motor drives the rotating screw to rotate forward. The rotating screw drives the linked screw ring disk to move left under the action of the thread. The rotating screw drives the hinged support rod to move left, and the hinged support rod drives the collar support block to move upward. The collar support block drives the support rod to move upward, and the support rod can drive the support collar block to move upward. The support collar block drives the outer ring nozzle to slide upward along the inner wall of the guide frame, so that multiple outer ring nozzles can be opened, and the bottom end of the outer ring nozzle is sensed by an infrared distance sensor. When the sensing distance is greater than the radius of the outer wall of the barrel by 20 cm, the driving motor can be stopped. In this way, the barrel product can be inserted into the gap formed between the multiple outer ring nozzles using a tool, and the inner wall of the barrel product is sleeved on the outside of the second collecting pipe.

[0015] Step 3. During water cooling, according to the data stored in the storage host and when the specified water spraying amount is input on the operation panel, the PLC controller can be used to control the closing of multiple first diversion electric control valves and the first electric control valve, as well as the closing of the second inner ring electric control valve, and the start of the suction pump, so that the suction pump draws the water inside the cooling water tank into the second flow controller, and introduces it into the input pipe through the second flow controller, and enters the water diversion pipe along the input pipe, and is input into multiple diversion pipes from the water diversion pipe, and enters the first diversion water pipe along the diversion pipe, and is introduced into the injection pipe from the first diversion water pipe, and is poured into the outer ring nozzle, and flows into multiple mist nozzles along the outer ring nozzle. The cooling water is directed to the second collecting pipe and then to the second collecting pipe, and the cooling water is directed to the plurality of inner ring atomizing nozzles for spraying. In this way, the inner ring atomizing nozzles can spray onto the inner wall of the cylinder to perform inner ring cooling operation. When the outer ring nozzle spraying time and the second collecting pipe spraying time set by the delay controller are the same as the stored time, the first diversion electric control valve and the second inner ring electric control valve can be closed to stop spraying. The water spraying amount is controlled by the second flow controller and is the same as the water spraying amount stored in the storage host, thereby completing water cooling control.

[0016] Step 4: When the oil is cooling, the heat absorption pump can be started by closing the second electric control valve, multiple second shunt electric control valves and the second inner ring electric control valve, so that the suction pipe can suck the cooling oil inside the cooling oil tank into the first flow controller for metering, and the first electric control valve can be opened to input the oil into the connecting pipe, and then into the first collecting pipe, and then injected into multiple export pipes through the first collecting pipe, and then into the two shunt oil pipes along the export pipe, and then into the inlet pipe along the shunt oil pipe, and then into the outer ring nozzle, and then dispersed to multiple atomizing nozzles by the outer ring nozzle, so that the atomizing nozzle can perform atomization spraying to cool down the outside of the cylinder, and at the same time, the first collecting pipe injects another part of the cooling oil into the inner In the annular oil pipe, it follows the inner ring oil pipe into the first inner ring electric control valve, and follows the first inner ring electric control valve into the second inner ring electric control valve. In this way, it can be injected into the outside of multiple inner ring atomizing nozzles through the second collecting pipe. In this way, multiple inner ring atomizing nozzles perform oil atomization cooling on the inner wall of the cylinder. When the oil atomization injection time of the outer ring nozzle and the oil atomization injection time of the second collecting pipe set by the delay controller are the same as the storage time, the first inner ring electric control valve and the first diversion electric control valve can be closed. In this way, the first flow controller performs flow control and monitors the used flow. In this way, oil atomization injection can be completed for cylinder products of different models, and online heat treatment process is realized.

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention adopts a control mechanism to input and store the cooling speed of each type of barrel and product size characteristic data into the storage host through the operation panel. Whether oil cooling or water cooling is required for barrels of different materials is recorded and stored in the storage host, and the cooling water spraying amount, as well as the water spraying time of the inner ring surface and the water spraying time of the outer ring surface are recorded. In this way, a database is formed. Each time it is used, the delay controller can be controlled by the PLC controller according to the data in the database. When the spraying time is the same as the stored time data, the water spraying time of the inner ring surface and the water spraying time of the outer ring surface can be controlled. When the specified time is reached, the cooling can be stopped. In this way, the cooling speed, cooling time, cooling water spraying amount required by the actual product, and the different spraying data of different materials, different inner diameters and outer diameters can be stored one by one. This makes control more convenient, greatly improves the efficiency of online heat treatment, is applicable to various types of barrels, is more convenient to use, and has better cooling effect.

[0019] 2. The present invention adopts a cooling mechanism to make the suction pump suck the water inside the cooling water tank into the second flow controller, follow the input pipe into the water distribution pipe, and then input into multiple guide pipes, follow the guide pipe into the first branch water pipe, pour into the outer ring nozzle, and flow into multiple atomizing nozzles along the outer ring nozzle to complete the outer ring water atomization cooling effect. One of the guide pipes is diverted to the second branch water pipe for external spraying, so that the inner ring cooling effect can be achieved on the inner wall of the cylinder. Start the heat absorption pump to make the suction pipe cool the inside of the oil tank, inject it into multiple outlet pipes through the first collecting pipe, and follow the outlet pipe into the two The oil in the oil pipe is dispersed into multiple atomizing nozzles by the outer ring nozzle, so that the atomizing nozzle can perform atomizing spray cooling on the outside of the cylinder, and inject the other part of the cooling oil into the inner ring oil pipe, and then inject it into the outside of multiple inner ring atomizing nozzles through the second collecting pipe. The inner ring atomizing nozzle performs oil atomizing cooling on the inner wall of the cylinder. In this way, the oil cooling or water cooling method can be changed according to the actual situation to perform dual cooling operation, and the inner ring cooling and outer ring cooling functions are realized in the cooling process, achieving all-round cooling operation, better cooling effect, making the online heat treatment more uniform, and greatly improving the online heat treatment effect;

[0020] 3. The present invention adopts a driving motor to drive the rotating screw to rotate forward, and the rotating screw drives the hinged support rod to move left, and the collar support block drives the support rod to move upward so that the support collar block moves upward, and the support collar block drives the outer ring nozzle to slide upward along the inner wall of the guide frame, and the support collar block drives the outer ring nozzle to slide upward along the inner wall of the guide frame. The bottom end of the outer ring nozzle is sensed by the infrared distance sensor. When the sensing distance length is greater than the radius of the outer wall of the cylinder by 20 cm, the driving motor is stopped. In this way, the cooling space of the cylinder with different inner and outer diameters can be adjusted according to actual conditions. This can be applicable to cylinders of different models with a wider range, and the length of each adjustment will always be 20 cm larger than the set length. This will ensure that the contact distance of the cylinder outside is the same after each adjustment, thereby ensuring that the uniformity of each external cooling is similar, thereby ensuring that the impact force when the flow rate is sprayed onto the outer ring surface of the cylinder is the same, thus ensuring better uniformity during cooling;

[0021] In summary, through the mutual influence of the above-mentioned multiple effects, the cooling speed, cooling time, cooling water spray volume required by the actual product, and the different data sprayed for different materials, different inner diameters and outer diameters can be stored one by one. This makes control more convenient and greatly improves the efficiency of online heat treatment. The double cooling operation can be changed according to the actual situation, and the inner ring cooling and outer ring cooling can be realized in the cooling process to achieve all-round cooling operation. It can be applied to different types of cylinders and has a wider applicability; and the length of each adjustment will always be twenty centimeters larger than the set length, which will ensure that the external contact distance of the cylinder is the same after each adjustment. In summary, the convenience of online heat treatment can be effectively improved, the processing efficiency can be improved, and the applicability of online heat treatment can be guaranteed at the same time, and the uniformity during processing can be improved, which both improves efficiency and ensures quality.

[0042] Step 3: During water cooling, according to the data stored in the storage host 16 and when the specified water spraying amount is input on the operation panel 15, the PLC controller 14 can be used to control the closing of multiple first diversion electric control valves 22 and the first electric control valve 6, as well as the closing of the second inner ring electric control valve 33, and start the suction pump 13, so that the suction pump 13 draws the water inside the cooling water tank 2 into the second flow controller 12, and introduces it into the input pipe 11 through the second flow controller 12, and enters the water diversion pipe 9 along the input pipe 11, and is input into multiple guide pipes 19 from the water diversion pipe 9, and enters the first diversion water pipe 21 along the guide pipe 19, and is introduced into the injection pipe 26 from the first diversion water pipe 21, and is poured into the outer ring nozzle 27, and flows along the outer ring nozzle 27. The cooling water flows into the plurality of atomizing nozzles 28 for atomization spraying, and at the same time, one of the guide pipes 19 is diverted into the second diversion water pipe 34, and flows along the second diversion water pipe 34 into the second collecting pipe 30. The second collecting pipe 30 guides the cooling water into the plurality of inner ring atomizing nozzles 29 for spraying. In this way, the inner ring atomizing nozzles 29 can spray onto the inner wall of the cylinder to perform inner ring cooling operation. When the spraying time of the outer ring nozzle 27 and the spraying time of the second collecting pipe 30 set by the delay controller 24 are the same as the stored time, the first diversion electric control valve 22 and the second inner ring electric control valve 33 can be closed to stop spraying. The water spraying amount is controlled by the second flow controller 12 and is the same as the water spraying amount stored in the storage host 16, thereby completing water cooling control.

[0043] Step 4: When the oil is cooling, the heat absorption pump 4 can be started by closing the second electric control valve 10, and closing multiple second shunt electric control valves 25 and the second inner ring electric control valve 33, so that the suction pipe 3 sucks the cooling oil inside the cooling oil tank 1 into the first flow controller 5 for metering, and the first electric control valve 6 is opened to input the oil into the connecting pipe 7, and enters the first collecting pipe 8 along the connecting pipe 7, and then is injected into multiple export pipes 17 through the first collecting pipe 8, and enters the two shunt oil pipes 20 along the export pipe 17, and enters the inlet pipe 23 along the shunt oil pipe 20, and is collected in the outer ring nozzle 27, and is dispersed by the outer ring nozzle 27 to multiple atomizing nozzles 28, so that the atomizing nozzle 28 can perform atomization spraying to cool down the outside of the cylinder, and at the same time the first collecting pipe 8 will send another part of the cooling oil Inject into the inner ring oil pipe 32, enter into the first inner ring electric control valve 31 along the inner ring oil pipe 32, and enter into the second inner ring electric control valve 33 along the first inner ring electric control valve 31. In this way, it can be injected into the outside of multiple inner ring atomizing nozzles 29 through the second collecting pipe 30. In this way, the inner wall of the cylinder is cooled by oil atomization by multiple inner ring atomizing nozzles 29. When the oil atomization injection time of the outer ring nozzle 27 set by the delay controller 24 and the oil atomization injection time of the second collecting pipe 30 are the same as the storage time, the first inner ring electric control valve 31 and the first diversion electric control valve 22 can be closed. In this way, the first flow controller 5 performs flow control and monitors the used flow. In this way, oil atomization injection can be completed for cylinder products of different models, and an online heat treatment process can be realized.
