Description

Technical Field

[0001] The present invention relates to the technical field of metal rolling, and specifically to an adjustable rolling device with a metal composite function. Background Art

[0002] Metal composite rolling occupies a quite important part in modern metal processing and manufacturing industries. By adding metals of other materials on the metal base layer, these metals are closely combined together. Without changing the mechanical properties of the metal base layer, it enables the metal to possess other excellent properties of metals, such as compressive resistance, rust prevention, wear resistance, anti-corrosion, etc. The metal composite rolling generally includes the following steps: metal blank composite, heating, surface descaling, hot rolling, cooling, and straightening. Since the plasticity of the metal is greatly improved after heating, hot rolling is required for metal composite. During the hot rolling process, the metal at a relatively high temperature often adheres to the surface of the rolling mill roll after deformation, causing the metal layer to be compounded on the base layer to be separated from the base metal again, resulting in a low qualified rate of metal composite. Even the surface of the rolling mill roll is overburned and turns blue, causing the rolling mill roll to slip with the metal and unable to continue working. After the compounded metal blank finishes rolling, it needs to be cooled down. During the cooling process of the compounded metal blank, the internal residual stress is released towards the surface layer, causing the compounded metal blank to deform. After cooling, it needs to be straightened repeatedly, which prolongs the manufacturing cycle of the composite metal and results in low production efficiency of the composite metal. Summary of the Invention

[0003] The purpose of the present invention is to provide an adjustable rolling device with a metal composite function to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the present invention provides the following technical solution: An adjustable rolling device with a metal composite function includes a metal blank to be compounded, and includes a bracket. A front conveyor chain, a rear conveyor chain, an electric furnace, a rolling mechanism, and a pair of inclined sliding side plates are arranged on the bracket. The front conveyor chain passes through the electric furnace, and the front conveyor chain is arranged on one side of the rolling mechanism. The pair of inclined sliding side plates are arranged on the side of the rolling mechanism away from the front conveyor chain. A cooling mechanism is arranged on the pair of inclined sliding side plates. The rear conveyor chain is arranged between the rolling mechanism and the cooling mechanism. The front conveyor chain and the rear conveyor chain convey the compounded metal blank. The electric furnace heats the compounded metal blank. The rolling mechanism compounds the compounded metal blank. The cooling mechanism cools and straightens the compounded metal blank.

[0005] Furthermore, the rolling mechanism includes two rolling sliders, an upper roller, a lower roller, and two hydraulic cylinders. The two rolling sliders are symmetrically arranged on the bracket and are slidably connected to the bracket. The upper roller is rotatably installed on the two rolling sliders, and the lower roller is rotatably installed on the bracket. The lower roller is aligned vertically with the upper roller and is located below the upper roller. The two hydraulic cylinders are symmetrically arranged on the bracket, and the piston rods of the two hydraulic cylinders are respectively connected to the two rolling sliders. Driven by the front conveying chain, the composite metal blank enters the electric furnace for heating. The two hydraulic cylinders simultaneously push the two rolling sliders to move, and the two rolling sliders drive the upper roller to move up and down to adjust the gap between the upper roller and the lower roller to adapt to the composite rolling of composite metal blanks with different thicknesses.

[0006] Furthermore, the rolling mechanism includes an upper sprocket, a lower sprocket, a power motor, and a reverse sprocket. The power motor is arranged on one side of the bracket, and a driving sprocket is installed on the motor shaft of the power motor. The upper sprocket is arranged on the side of the upper roller close to the driving sprocket, and the lower sprocket is arranged on the side of the lower roller close to the driving sprocket. The reverse sprocket is rotatably installed on the bracket and is in meshing transmission with the lower sprocket. The same chain is connected to the upper sprocket, the reverse sprocket, and the driving sprocket.

[0007] A tensioning arm is also rotatably installed on the bracket. A coil spring is arranged at the connection between the tensioning arm and the bracket. A tensioning wheel is rotatably installed on the tensioning arm, and the tensioning wheel is in contact with the chain. When the power motor is energized to start working, the driving sprocket starts to rotate, driving the upper sprocket and the reverse sprocket to rotate simultaneously through the chain. The driving sprocket, the reverse sprocket, and the lower sprocket are of the same size. The reverse sprocket drives the lower sprocket to rotate, causing the upper sprocket and the lower sprocket to rotate in opposite directions and at the same speed. The upper sprocket rotates synchronously with the upper roller, and the lower sprocket rotates synchronously with the lower roller. The composite metal blank is rolled through the middle of the upper roller and the lower roller. When the two hydraulic cylinders drive the two rolling sliders to move downward, the distance between the upper roller and the driving sprocket shortens, and the chain becomes slack. Under the action of the coil spring, the tensioning arm ensures that the tensioning wheel always remains in contact with the chain. The tensioning wheel pushes the chain outward to keep the chain taut, ensuring the effective operation of the chain when the center distance between the two sprockets in the chain drive changes. Using the same power motor to drive the upper roller and the lower roller to rotate simultaneously can avoid the instability of the rotation synchronization rate when using two motors, further reducing the friction between the rollers and the composite metal blank, extending the service life of the rollers, and improving the surface quality of the composite metal blank rolling.

[0008] Furthermore, the upper roll is hollow, and a hollow auger and a diameter-reducing auger are arranged inside the upper roll. The diameter-reducing auger is located on the side of the upper roll close to the upper sprocket, and the hollow auger is located on the side of the upper roll far from the upper sprocket. A partition is arranged between the hollow auger and the diameter-reducing auger. One end of the diameter-reducing auger close to the partition extends into the interior of the hollow auger. A hollow auger and a diameter-reducing auger are also arranged inside the lower roll. The arrangement of the hollow auger and the diameter-reducing auger inside the lower roll is the same as that of the upper roll. While the upper roll and the lower roll are working, the second water pump is powered on to pump the water in the water tank and input it into the upper roll and the lower roll through the water pipe. The water flowing into the upper roll is divided into external water flow and internal water flow. The external water flow flows through the position between the diameter-reducing auger and the upper roll, and the water rotates along the contour of the diameter-reducing auger and fits against the inner wall of the upper roll under the action of centrifugal force, and takes away the heat conducted from the composite metal blank to the upper roll, and then enters the interior of the hollow auger and flows out towards the water return pipe; the internal water flow flows from the interior of the diameter-reducing auger to the position between the hollow auger and the upper roll, takes away the heat on the upper roll, and then flows into the water return pipe. The water flowing into the upper roll is divided into two parts to cool the surface of the roll, ensuring more uniform heat dissipation on the surface of the upper roll and higher heat dissipation efficiency. The water is introduced into the lower roll for heat dissipation in the same way.

[0009] Furthermore, the rolling mechanism includes an upper feeding shaft, a lower feeding shaft, a powder box, and a collection box. The upper feeding shaft is arranged on the upper two rolling slider blocks, and the upper feeding shaft is located on one side of the upper roll. Mineral powder is stored in the powder box. An air pump is arranged on one side of each of the upper feeding shaft and the lower feeding shaft. A suction pipe is connected to the side of each of the upper feeding shaft and the lower feeding shaft where the air pump is installed. One end of each of the two suction pipes is located in the powder box. A return pipe is connected to the other side of each of the upper feeding shaft and the lower feeding shaft. One end of each of the two return pipes is located in the collection box.

[0010] Further, long conical round holes are formed inside the upper feeding shaft and the lower feeding shaft. A narrow slit is formed on the upper feeding shaft, and the narrow slit communicates with the long conical round hole. The narrow slit on the upper feeding shaft is close to the upper rolling roll. The lower feeding shaft is also internally provided with a long conical round hole and a narrow slit. The opening modes of the long conical round hole and the narrow slit in the lower feeding shaft are the same as those of the upper feeding shaft. The upper rolling roll and the lower rolling roll are connected to the negative pole of a DC circuit, and the DC circuit charges negative charges to the surfaces of the upper rolling roll and the lower rolling roll. The air pump works simultaneously, and the gas flows through the upper feeding shaft and the lower feeding shaft. Since the gas flow rate in the upper feeding shaft and the lower feeding shaft increases, the internal air pressure decreases. The pressure at the end of the suction pipe extending into the powder box is greater than the pressure at the end where the suction pipe is connected to the upper feeding shaft and the lower feeding shaft. The mineral powder enters the upper feeding shaft and the lower feeding shaft through the suction pipe, and is mixed with the air flow flowing through the upper feeding shaft and the lower feeding shaft. An electric field is generated by the negative charges on the upper rolling roll and the lower rolling roll, and the electric field adsorbs the mineral powder through the narrow slit, so that the mineral powder is evenly attached to the surfaces of the upper rolling roll and the lower rolling roll. The remaining mineral powder enters the collection box through the return pipe for recycling. When rolling the composite metal blank, the mineral powder enables the upper rolling roll and the lower rolling roll to be in indirect contact with the composite metal blank, avoiding adhesion between the upper rolling roll and the lower rolling roll and the composite metal blank. During the process of the air flow flowing in the upper feeding shaft and the lower feeding shaft, the kinetic energy gradually decreases. The air flow flows from the side with a larger cross-section of the long conical round hole to the side with a smaller cross-section, stabilizing the flow rate of the air flow and compensating for the loss of air pressure through the narrow slit, so that the mixture of the mineral powder and the gas remains uniform. When the upper rolling roll and the lower rolling roll roll the composite metal blank, the mineral powder remains on the composite metal blank, and in the subsequent cooling process, it also plays a role in preventing adhesion to the straightened steel plate.

[0011] Further, the cooling mechanism includes a gland, a movable cooling cover, a fixed cooling seat, a frame-shaped plate, and a pair of lifting cylinders. The gland is slidably installed on a pair of inclined sliding side plates. The movable cooling cover is arranged below the gland, and several boosting springs are arranged between the movable cooling cover and the gland. The fixed cooling seat is arranged between the pair of inclined sliding side plates and is located below the movable cooling cover. A cross bar is arranged at the bottom of the gland. The pair of lifting cylinders are arranged on the bracket, the frame-shaped plate is arranged on the pair of lifting cylinders, and the cross bar is slidably installed in the frame-shaped plate.

[0012] Further, a retaining edge is provided at one end of the movable cooling cover close to the fixed cooling seat. A clamping groove is provided at the position of the fixed cooling seat corresponding to the retaining edge. A plurality of atomizing nozzles are arranged inside the movable cooling cover. One end of each of the plurality of atomizing nozzles is connected to a water inlet pipe. One end of the water inlet pipe is connected to a water tank, and a water pump is arranged in the middle of the water inlet pipe. A pressure-adjusting steel plate is arranged at the water spraying end of the atomizing nozzles in the movable cooling cover. A plurality of atomizing nozzles and pressure-adjusting steel plates are also arranged inside the fixed cooling seat. The arrangement mode of the plurality of atomizing nozzles and pressure-adjusting steel plates inside the fixed cooling seat is the same as that inside the movable cooling cover. A blocking block is slidably arranged on the fixed cooling seat. An electromagnet is installed below the blocking block. The blocking block and the electromagnet are arranged in the same control circuit. The rolled composite metal blank comes to the fixed cooling seat through the conveying of the rear conveying chain. The fixed cooling seat is inclined. An unloading mechanism is arranged on one side of the fixed cooling seat. The unloading mechanism includes an electric telescopic cylinder and a second electromagnet. The second electromagnet is installed on the piston rod of the electric telescopic cylinder. When the composite metal blank needs to be moved, the second electromagnet is powered on and adsorbs the composite metal blank, driving the composite metal blank to slide on the fixed cooling seat. After the composite metal blank is blocked by the blocking block, the second electromagnet is powered off, and the electric telescopic cylinder drives the second electromagnet to retract. A pair of lifting cylinders starts to work, driving the pressing cover to slide down through the frame-shaped plate. The pressing cover makes the movable cooling cover move down through the pressure-increasing spring, and the retaining edge is embedded into the clamping groove. The pressure-increasing spring plays a role in shock absorption. The two pressure-adjusting steel plates press the upper and lower surfaces of the composite metal blank. The two pressure-adjusting steel plates are in a mesh shape. The water pump supplies water to the atomizing nozzles through the water inlet pipe. The water mist is sprayed onto the upper and lower surfaces of the composite metal blank through the mesh-shaped pressure-adjusting steel plates to cool the composite metal blank. During the gradual cooling process of the composite metal blank, the hardness of the composite metal blank increases, and the internal residual stress is gradually released. By firmly pressing the surface of the composite metal blank with the two pressure-adjusting steel plates, straightening of the composite metal blank is achieved while the cooling of the composite metal blank ends, saving the production time of the composite metal blank and improving the processing efficiency of the composite metal blank.

[0013] Further, one end of the upper roller close to the upper sprocket is rotatably connected to a water pipe. One end of the water pipe is connected to a water tank, and a second water pump is arranged in the middle of the water pipe. One end of the lower roller close to the lower sheave is also rotatably connected to the water pipe. The ends of the upper roller and the lower roller far from the water pipe are connected to a return water pipe.

[0014] Furthermore, the cooling mechanism further includes a steam pipe and a heating spiral pipe. One end of the steam pipe is connected with a branch pipe, and the branch pipe is respectively connected to the inside of the movable cooling cover and the fixed cooling seat. The heating spiral pipe is arranged on one side of the electric furnace away from the rear conveying chain. The steam pipe penetrates through the water return pipe, and the steam pipe is communicated with the heating spiral pipe. When the water mist cools the composite metal blank, high-temperature water vapor is generated. The water vapor is introduced into the heating spiral pipe through the steam pipe. Fins are arranged on the heating spiral pipe, and the heat of the water vapor is conducted to the fins, raising the temperature of the air around the fins, preheating the composite metal blank entering the electric furnace, saving the heating time of the composite metal blank, reducing the power consumption of the electric furnace. The water flow in the water return pipe absorbs the surface temperature of the upper roller and the lower roller. The steam pipe is arranged in the water return pipe, effectively reducing the temperature loss of the water vapor during the transmission process. After the cooling of the composite metal blank is completed, the control circuit makes the electromagnet energized, adsorbing the blocking block to move downward, releasing the block on the composite metal blank. The electric telescopic cylinder uses the second electromagnet to adsorb the composite metal blank again, and the electric telescopic cylinder drives the composite metal blank to slide on the inclined surface of the fixed cooling seat, so as to realize the blanking of the composite metal blank and enter the subsequent production and processing links.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0016] 1. Using a DC circuit to charge negative charges onto the surfaces of the upper roller and the lower roller, sucking mineral powder into the upper feeding shaft and the lower feeding shaft through an air pump. The negative charges on the upper roller and the lower roller generate an electric field, and the electric field adsorbs the mineral powder through the narrow slits. The mineral powder makes the upper roller and the lower roller indirectly contact the composite metal blank, avoiding adhesion between the upper roller and the lower roller and the composite metal blank. When the upper roller and the lower roller roll the composite metal blank, the mineral powder remains on the composite metal blank and also plays a role in preventing adhesion to the leveling steel plate during the cooling process.

[0017] 2. When the water mist cools the composite metal blank, high-temperature water vapor is generated. The water vapor is introduced into the heating spiral pipe through the steam pipe. Fins are arranged on the heating spiral pipe, and the heat of the water vapor is conducted to the fins, raising the temperature of the air around the fins, preheating the composite metal blank entering the electric furnace, saving the heating time of the composite metal blank, reducing the power consumption of the electric furnace. The water flow in the water return pipe absorbs the surface temperature of the upper roller and the lower roller. The steam pipe is arranged in the water return pipe, effectively reducing the temperature loss of the water vapor during the transmission process.

[0018] 3. Use the same driving motor to drive the upper roll and the lower roll to rotate simultaneously, avoiding the unstable rotation synchronization rate when using two motors, further reducing the friction between the roll and the composite metal blank, prolonging the service life of the roll, and improving the surface quality of the rolled composite metal blank.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-8 , the present invention provides a technical solution: an adjustable rolling device with a metal composite function, including a metal blank to be composite, a bracket 1, a front conveying chain 201, a rear conveying chain 202, an electric furnace 3, a rolling mechanism, and a pair of inclined sliding side plates 21 are arranged on the bracket 1. The front conveying chain 201 passes through the electric furnace 3. The front conveying chain 201 is arranged on one side of the rolling mechanism. A pair of inclined sliding side plates 21 are arranged on the side of the rolling mechanism away from the front conveying chain 201. A cooling mechanism is arranged on the pair of inclined sliding side plates 21. The rear conveying chain 202 is arranged between the rolling mechanism and the cooling mechanism. The front conveying chain 201 and the rear conveying chain 202 convey the composite metal blank. The electric furnace 3 heats the composite metal blank. The rolling mechanism composites the composite metal blank. The cooling mechanism cools and straightens the composite metal blank.

[0031] The rolling mechanism includes two rolling slider blocks 5, an upper rolling roll 601, a lower rolling roll 602, and two hydraulic cylinders 4. The two rolling slider blocks 5 are symmetrically arranged on the bracket 1. The two rolling slider blocks 5 are slidably connected to the bracket 1. The upper rolling roll 601 is rotatably installed on the two rolling slider blocks 5. The lower rolling roll 602 is rotatably installed on the bracket 1. The lower rolling roll 602 is aligned with the upper rolling roll 601 up and down. The lower rolling roll 602 is located below the upper rolling roll 601. The two hydraulic cylinders 4 are symmetrically arranged on the bracket 1. The piston rods of the two hydraulic cylinders 4 are respectively connected to the two rolling slider blocks 5. The rolling mechanism includes an upper sprocket 701, a lower sprocket 702, a power motor 9, and a reverse sprocket. The power motor 9 is arranged on one side of the bracket 1. A driving sprocket 703 is installed on the motor shaft of the power motor 9. The upper sprocket 701 is arranged on the side of the upper rolling roll 601 close to the driving sprocket 703. The lower sprocket 702 is arranged on the side of the lower rolling roll 602 close to the driving sprocket 703. The reverse sprocket is rotatably installed on the bracket 1. The reverse sprocket is meshed and driven with the lower sprocket 702. The upper sprocket 701, the reverse sprocket, and the driving sprocket 703 are connected by the same chain 8. A tensioning arm 10 is also rotatably installed on the bracket 1. A coil spring is arranged at the connection between the tensioning arm 10 and the bracket 1. A tensioning wheel 11 is rotatably installed on the tensioning arm 10. The tensioning wheel 11 is in contact with the chain 8.

[0032] Driven by the front conveyor chain 201, the composite metal blank enters the electric furnace 3 for heating. Two hydraulic cylinders 4 simultaneously push two roller sliders 5 to move, and the two roller sliders 5 drive the upper roller 601 to move up and down, adjusting the gap between the upper roller 601 and the lower roller 602 to adapt to the composite rolling of composite metal blanks with different thicknesses. The power motor 9 is energized to start working, and the driving sprocket 703 starts to rotate. Through the chain 8, the upper sprocket 701 and the reverse sprocket are driven to rotate simultaneously. The driving sprocket 703, the reverse sprocket, and the lower sprocket 702 are of the same size. The reverse sprocket drives the lower sprocket 702 to rotate, causing the upper sprocket 701 and the lower sprocket 702 to rotate in opposite directions and at the same speed. The upper sprocket 701 rotates synchronously with the upper roller 601, and the lower sprocket 702 rotates synchronously with the lower roller 602. The composite metal blank is rolled through the middle of the upper roller 601 and the lower roller 602. When the two hydraulic cylinders 4 drive the two roller sliders 5 to move downward, the distance between the upper roller 601 and the driving sprocket 703 shortens, and the chain 8 becomes slack. Under the action of the coil spring, the tensioning arm 10 keeps the tensioning wheel 11 in contact with the chain 8 all the time. The tensioning wheel 11 pushes the chain 8 outward to keep the chain 8 taut, ensuring that the chain 8 can work effectively when the center distance between the two sprockets in the chain drive changes. Using the same power motor 9 to drive the upper roller 601 and the lower roller 602 to rotate simultaneously avoids the situation of unstable rotation synchronization rate when using two motors, further reduces the friction between the rollers and the composite metal blank, extends the service life of the rollers, and improves the surface quality of the composite metal blank rolling.

[0033] The upper roll 601 is hollowly arranged. Inside the upper roll 601, there are a hollow auger 121 and a reducing auger 122. The reducing auger 122 is located on the side of the upper roll 601 close to the upper sprocket 701, and the hollow auger 121 is located on the side of the upper roll 601 far from the upper sprocket 701. A partition is arranged between the hollow auger 121 and the reducing auger 122. One end of the reducing auger 122 close to the partition extends into the inside of the hollow auger 121. Inside the lower roll 602, there are also a hollow auger 121 and a reducing auger 122. The arrangement of the hollow auger 121 and the reducing auger 122 inside the lower roll 602 is the same as that of the upper roll 601. One end of the upper roll 601 close to the upper sprocket 701 is rotatably connected to a water pipe 19. One end of the water pipe 19 is connected to a water tank. A second water pump (not shown in the figure) is arranged in the middle of the water pipe 19. One end of the lower roll 602 close to the lower sheave 702 is also rotatably connected to the water pipe 19. One ends of the upper roll 601 and the lower roll 602 far from the water pipe 19 are connected to a return water pipe 20. While the upper roll 601 and the lower roll 602 are working, the second water pump is powered on to pump the water in the water tank and input it into the upper roll 601 and the lower roll 602 through the water pipe 19. The water flowing into the upper roll 601 is divided into external water flow and internal water flow. The external water flow flows through the position between the reducing auger 122 and the upper roll 601. The water flow rotates along the contour of the reducing auger 122 and fits against the inner wall of the upper roll 601 under the action of centrifugal force, and takes away the heat conducted from the composite metal blank to the upper roll 601, and then enters the inside of the hollow auger 121 and flows out towards the return water pipe 20. The internal water flow flows from the inside of the reducing auger 122 to the position between the hollow auger 121 and the upper roll 601, takes away the heat on the upper roll 601, and then flows into the return water pipe 20. Dividing the water flow flowing into the upper roll 601 into two parts to cool the surface of the roll can ensure more uniform heat dissipation on the surface of the upper roll 601 and higher heat dissipation efficiency. The water is introduced into the lower roll 602 for heat dissipation in the same way.

[0034] The rolling mechanism includes an upper feeding shaft 131, a lower feeding shaft 132, a powder box 16, and a collection box 18. The upper feeding shaft 131 is arranged on the upper two rolling slider 5, and the upper feeding shaft 131 is located on one side of the upper rolling roll 601. Mineral powder is stored in the powder box 16. An air pump 14 is arranged on one side of both the upper feeding shaft 131 and the lower feeding shaft 132. A suction pipe 15 is connected to the side of the upper feeding shaft 131 and the lower feeding shaft 132 where the air pump 14 is installed. One end of the two suction pipes 15 is located in the powder box 16. A return pipe 17 is connected to the other side of both the upper feeding shaft 131 and the lower feeding shaft 132. One end of the two return pipes 17 is located in the collection box 18. Long conical round holes are opened inside the upper feeding shaft 131 and the lower feeding shaft 132. A narrow slit is opened on the upper feeding shaft 131, and the narrow slit communicates with the long conical round hole. The narrow slit on the upper feeding shaft 131 is close to the upper rolling roll 601. Long conical round holes and narrow slits are also opened inside the lower feeding shaft 132. The opening methods of the long conical round holes and narrow slits in the lower feeding shaft 132 are the same as those of the upper feeding shaft 131. The upper rolling roll 601 and the lower rolling roll 602 are connected to the negative pole of a DC circuit. The DC circuit charges negative charges onto the surfaces of the upper rolling roll 601 and the lower rolling roll 602. The air pumps 14 work simultaneously, and gas flows through the upper feeding shaft 131 and the lower feeding shaft 132. Since the gas flow rate in the upper feeding shaft 131 and the lower feeding shaft 132 increases, the internal air pressure decreases. The pressure at the end of the suction pipe 15 extending into the powder box 16 is greater than the end where the suction pipe 15 is connected to the upper feeding shaft 131 and the lower feeding shaft 132. The mineral powder enters the upper feeding shaft 131 and the lower feeding shaft 132 through the suction pipe 15 and mixes with the air flow flowing through the upper feeding shaft 131 and the lower feeding shaft 132 to form a whole. An electric field is generated by the negative charges on the upper rolling roll 601 and the lower rolling roll 602. The electric field adsorbs the mineral powder through the narrow slit, making the mineral powder evenly adhere to the surfaces of the upper rolling roll 601 and the lower rolling roll 602. The remaining mineral powder enters the collection box 18 through the return pipe 17 for recycling. When rolling the composite metal blank, the mineral powder makes the upper rolling roll 601 and the lower rolling roll 602 indirectly contact the composite metal blank, avoiding adhesion between the upper rolling roll 601 and the lower rolling roll 602 and the composite metal blank. During the process of the air flow flowing in the upper feeding shaft 131 and the lower feeding shaft 132, the kinetic energy gradually decreases. The air flow flows from the side with a larger cross-sectional area of the long conical round hole to the side with a smaller cross-sectional area, stabilizing the flow rate of the air flow and compensating for the loss of air pressure through the narrow slit, so that the mixture of the mineral powder and the gas remains uniform. When the upper rolling roll 601 and the lower rolling roll 602 roll the composite metal blank, the mineral powder remains on the composite metal blank and also plays a role in preventing adhesion to the leveling and pressing steel plate 27 in the subsequent cooling process.

[0035] The cooling mechanism includes a gland 22, a movable cooling cover 24, a fixed cooling seat 25, a frame-shaped plate 29, and a pair of lifting cylinders 30. The gland 22 is slidably mounted on a pair of inclined sliding side plates 21. The movable cooling cover 24 is disposed below the gland 22. A plurality of pressurizing springs 23 are provided between the movable cooling cover 24 and the gland 22. The fixed cooling seat 25 is disposed between the pair of inclined sliding side plates 21 and is located below the movable cooling cover 24. A cross bar is provided at the bottom of the gland 22. A pair of lifting cylinders 30 are provided on the bracket 1. The frame-shaped plate 29 is provided on the pair of lifting cylinders 30. The cross bar is slidably mounted in the frame-shaped plate 29. One end of the movable cooling cover 24 close to the fixed cooling seat 25 is provided with a stop edge. A card slot is provided at the position of the fixed cooling seat 25 corresponding to the stop edge. A plurality of atomizing nozzles 26 are provided inside the movable cooling cover 24. The plurality of atomizing nozzles 26 are all connected to a water inlet pipe. One end of the water inlet pipe is connected to a water tank, and a water pump is provided in the middle of the water inlet pipe. The movable cooling cover 24 is provided with a pressure correcting steel plate 27 corresponding to the water spraying end of the atomizing nozzle 26. A plurality of atomizing nozzles 26 and pressure correcting steel plates 27 are also provided inside the fixed cooling seat 25. The arrangement of the plurality of atomizing nozzles 26 and pressure correcting steel plates 27 inside the fixed cooling seat 25 is the same as that inside the movable cooling cover 24. A stop block 28 is slidably provided on the fixed cooling seat 25. An electromagnet is installed below the stop block 28. The stop block 28 and the electromagnet are arranged in the same control circuit. The rolled composite metal blank comes to the fixed cooling seat 25 through the conveying of the rear conveying chain 202. The fixed cooling seat 25 is inclined. An unloading mechanism (not shown in the figure) is provided on one side of the fixed cooling seat 25. The unloading mechanism includes an electric telescopic cylinder and a second electromagnet. The second electromagnet is installed on the piston rod of the electric telescopic cylinder. When it is necessary to move the composite metal blank, the second electromagnet is energized and adsorbs the composite metal blank, driving the composite metal blank to slide on the fixed cooling seat 25. After the composite metal blank is blocked by the stop block 28, the second electromagnet is powered off, and the electric telescopic cylinder drives the second electromagnet to retract. The unloading mechanism drives the composite metal blank to slide on the fixed cooling seat 25. The composite metal blank is blocked by the stop block 28. The pair of lifting cylinders 30 start to work, driving the gland 22 to slide down through the frame-shaped plate 29. The gland 22 makes the movable cooling cover 24 move down through the pressurizing springs 23, and the stop edge is inserted into the card slot. The pressurizing springs 23 play a role in shock absorption. The two pressure correcting steel plates 27 press the upper and lower surfaces of the composite metal blank. The two pressure correcting steel plates 27 are in a mesh shape. The water pump supplies water to the atomizing nozzles 26 through the water inlet pipe. The water mist is sprayed onto the upper and lower surfaces of the composite metal blank through the mesh-shaped pressure correcting steel plates 27 to cool the composite metal blank. During the gradual cooling process of the composite metal blank, the hardness of the composite metal blank increases, and the internal residual stress is gradually released. By firmly pressing the surface of the composite metal blank with the two pressure correcting steel plates 27, the straightening of the composite metal blank is achieved while the cooling of the composite metal blank ends, saving the production time of the composite metal blank.Improve the processing efficiency of composite metal billets.

[0036] The cooling mechanism further includes a steam pipe 31 and a heating spiral pipe 32. One end of the steam pipe 31 is connected with a branch pipe, and the branch pipe is respectively connected to the inside of the movable cooling cover 24 and the fixed cooling seat 25. The heating spiral pipe 32 is arranged on one side of the electric furnace 3 away from the rear conveying chain 202. The steam pipe 31 penetrates through the water return pipe 20, and the steam pipe 31 is communicated with the heating spiral pipe 32. When the water mist cools the composite metal billet, high-temperature water vapor is generated. The water vapor is introduced into the heating spiral pipe 32 through the steam pipe 31. Fins (not shown in the figure) are arranged on the heating spiral pipe 32. The heat of the water vapor is conducted to the fins, so that the air temperature around the fins rises, and the composite metal billet entering the electric furnace 3 is preheated, saving the heating time of the composite metal billet and reducing the power consumption of the electric furnace 3. The water flow in the water return pipe 20 absorbs the temperature on the surfaces of the upper roller 601 and the lower roller 602. The steam pipe 31 is arranged in the water return pipe 20, effectively reducing the temperature loss of the water vapor during the transmission process. After the cooling of the composite metal blank is completed, the control circuit makes the electromagnet energized, adsorbing the block 28 to move downward, releasing the blockage of the composite metal blank, and the electric telescopic cylinder uses the second electromagnet to adsorb the composite metal blank again. The electric telescopic cylinder drives the composite metal blank to slide on the inclined surface of the fixed cooling seat 25, so as to realize the blanking of the composite metal blank and enter the subsequent production and processing links.

[0037] The working principle of the present invention: When using the device to perform composite rolling on a composite metal billet, the composite metal billet is driven by the front conveying chain 201 and enters the electric furnace 3 for heating. The two hydraulic cylinders 4 simultaneously push the two roller sliders 5 to move. The two roller sliders 5 drive the upper roller 601 to move up and down, adjusting the gap between the upper roller 601 and the lower roller 602 to adapt to the composite rolling of composite metal billets with different thicknesses. The power motor 9 is energized to start working, and the driving sprocket 703 starts to rotate. The chain 8 drives the upper sprocket 701 and the reverse sprocket to rotate simultaneously. The driving sprocket 703, the reverse sprocket and the lower sprocket 702 are of the same size. The reverse sprocket drives the lower sprocket 702 to rotate, so that the upper sprocket 701 and the lower sprocket 702 rotate in opposite directions and at the same speed. The upper sprocket 701 rotates synchronously with the upper roller 601, and the lower sprocket 702 rotates synchronously with the lower roller 602. The composite metal billet is rolled through the middle of the upper roller 601 and the lower roller 602. When the two hydraulic cylinders 4 drive the two roller sliders 5 to move downward, the distance between the upper roller 601 and the driving sprocket 703 shortens, and the chain 8 becomes loose. Under the action of the coil spring, the tension arm 10 makes the tension wheel 11 always keep in contact with the chain 8. The tension wheel 11 pushes the chain 8 outward to keep the chain 8 taut.

[0038] While the upper roll 601 and the lower roll 602 are working, the second water pump is powered on to pump the water in the water tank and input it into the upper roll 601 and the lower roll 602 through the water pipe 19. The water flowing into the upper roll 601 is divided into external water flow and internal water flow. The external water flow flows through the position between the diameter-reducing auger 122 and the upper roll 601. The water flow rotates along the contour of the diameter-reducing auger 122 and adheres to the inner wall of the upper roll 601 under the action of centrifugal force, and takes away the heat conducted by the composite metal blank to the upper roll 601. Then it enters the interior of the hollow auger 121 and flows out towards the water return pipe 20. The internal water flow flows from the interior of the diameter-reducing auger 122 to the position between the hollow auger 121 and the upper roll 601, takes away the heat on the upper roll 601, and then flows into the water return pipe 20. The water flowing into the upper roll 601 is divided into two parts to cool the surface of the roll, ensuring more uniform heat dissipation on the surface of the upper roll 601 and higher heat dissipation efficiency. The water is introduced into the lower roll 602 for heat dissipation in the same way.

[0039] The DC circuit charges negative charges onto the surfaces of the upper roll 601 and the lower roll 602. The air pump 14 works simultaneously. The gas flows through the upper feeding shaft 131 and the lower feeding shaft 132. Since the gas flow rate in the upper feeding shaft 131 and the lower feeding shaft 132 increases, the internal air pressure decreases. The pressure at one end of the suction pipe 15 extending into the powder box 16 is greater than the pressure at the end where the suction pipe 15 is connected to the upper feeding shaft 131 and the lower feeding shaft 132. The mineral powder enters the upper feeding shaft 131 and the lower feeding shaft 132 through the suction pipe 15 and is mixed with the air flow flowing through the upper feeding shaft 131 and the lower feeding shaft 132. The negative charges on the upper roll 601 and the lower roll 602 generate an electric field, and the electric field adsorbs the mineral powder through the narrow slit, making the mineral powder evenly adhere to the surfaces of the upper roll 601 and the lower roll 602. The remaining mineral powder enters the collection box 18 through the return pipe 17 for recycling. When rolling the composite metal blank, the mineral powder makes the upper roll 601 and the lower roll 602 indirectly contact the composite metal blank, avoiding adhesion between the upper roll 601 and the lower roll 602 and the composite metal blank. During the process of the air flow flowing through the upper feeding shaft 131 and the lower feeding shaft 132, the kinetic energy gradually decreases. The air flow flows from the side with a larger cross-sectional area of the long conical round hole to the side with a smaller cross-sectional area, stabilizing the flow rate of the air flow and compensating for the loss of air pressure through the narrow slit, so that the mixture of the mineral powder and the gas remains uniform. When the upper roll 601 and the lower roll 602 roll the composite metal blank, the mineral powder remains on the composite metal blank and also plays a role in preventing adhesion to the straightening and pressing steel plate 27 in the subsequent cooling process.

[0040] The rolled composite metal blank is conveyed to the fixed cooling seat 25 by the rear conveying chain 202. The fixed cooling seat 25 is inclined. An unloading mechanism is arranged on one side of the fixed cooling seat 25. The unloading mechanism includes an electric telescopic cylinder and a second electromagnet. The second electromagnet is installed on the piston rod of the electric telescopic cylinder. When it is necessary to move the composite metal blank, the second electromagnet is energized and adsorbs the composite metal blank, driving the composite metal blank to slide on the fixed cooling seat 25. After the composite metal blank is blocked by the stopper 28, the second electromagnet is powered off, and the electric telescopic cylinder drives the second electromagnet to retract. A pair of lifting cylinders 30 start to work, driving the pressing cover 22 to slide down through the frame-shaped plate 29. The pressing cover 22 makes the movable cooling cover 24 move down through the boosting spring 23, and the blocking edge is embedded in the card slot. The boosting spring 23 plays a role in shock absorption. Two straightening and pressing steel plates 27 press the upper and lower surfaces of the composite metal blank. The two straightening and pressing steel plates 27 are in a mesh shape. The water pump supplies water to the atomizing nozzle 26 through the water inlet pipe. The water mist is sprayed onto the upper and lower surfaces of the composite metal blank through the mesh-shaped straightening and pressing steel plates 27 to cool the composite metal blank. During the gradual cooling process of the composite metal blank, the hardness of the composite metal blank increases, and the internal residual stress is gradually released. By firmly pressing the surface of the composite metal blank with the two straightening and pressing steel plates 27, when the cooling of the composite metal blank ends, the straightening of the composite metal blank is achieved, saving the production time of the composite metal blank and improving the processing efficiency of the composite metal blank.

[0041] When the water mist cools the composite metal blank, high-temperature water vapor is generated. The water vapor is introduced into the heating spiral tube 32 through the steam pipe 31. The heating spiral tube 32 is provided with fins. The heat of the water vapor is conducted to the fins, raising the temperature of the air around the fins, preheating the composite metal blank entering the electric furnace 3, saving the heating time of the composite metal blank, reducing the power consumption of the electric furnace 3. The water flow in the return pipe 20 absorbs the temperature on the surfaces of the upper roller 601 and the lower roller 602. The steam pipe 31 is arranged in the return pipe 20, effectively reducing the temperature loss of the water vapor during the transmission process. After the composite metal blank is cooled, the control circuit makes the electromagnet energized, adsorbing the stopper 28 to move down, releasing the block on the composite metal blank. The electric telescopic cylinder uses the second electromagnet to adsorb the composite metal blank again, and the electric telescopic cylinder drives the composite metal blank to slide on the inclined surface of the fixed cooling seat 25, so as to unload the composite metal blank and enter the subsequent production and processing links.
