Description

Technical Field

[0001] This invention relates to the field of titanium alloy rolling technology, specifically a continuous rolling device for titanium alloy plates. Background Technology

[0002] Roll forming is a metal forming process that uses a series of specially shaped rolls to continuously deform metal and form a predetermined shape under pressure. Titanium alloys have high deformation resistance, poor plasticity and severe springback at room temperature. Therefore, the rolling process generally needs to be combined with heating or subsequent shaping to achieve high-precision forming.

[0003] Under current technology, due to the short processing window of titanium alloys, most of them need to be formed by multiple passes or multiple heating cycles. Heating is required between each pass to bring the temperature of the plate to the phase transformation temperature range, which makes the processing time lengthy. At the same time, each additional heating cycle increases the oxidation degree of the titanium alloy when exposed to air. Furthermore, the temperature drop during transportation cannot be controlled, which seriously affects the processing quality of the plate. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous rolling device for titanium alloy plates to solve the problem in the prior art that the long processing time of multiple passes affects the quality of plate processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The continuous rolling mill for titanium alloy plates includes a base, on which a roughing section and a finishing section are disposed; a temperature control device is disposed between the roughing section and the finishing section; and a cleaning component is disposed on the side of the roughing section away from the finishing section. The temperature control unit includes a heating element, a cooling element, a first mounting plate, and an infrared thermometer. The first mounting plate is installed on the roughing section near the finishing section. Multiple infrared thermometers are installed on the first mounting plate, and the multiple infrared thermometers are arranged linearly. The heating element and the cooling element are provided on the base. The heating element includes a U-shaped coil, and the base is equipped with the U-shaped coil. The infrared thermometer controls the operation of the U-shaped coil and the cooling element, so that the temperature control element keeps the plate within the processing temperature range. The excess heat of the heating element is used to improve the cleaning quality of the cleaning element. When the titanium alloy plate needs to be rolled, the plate is fed from the roughing section and heated. The plate undergoes preliminary rolling in the roughing section. The plate will cool down due to heat dissipation and heat conduction of the pressure roller. At this time, the heating element heats the area with a temperature lower than the working temperature to ensure that the plate is within the working temperature range. At the same time, the plate may also increase in temperature due to deformation during rolling. At this time, the cooling element can cool the area with a temperature higher than the working temperature. Overall, the temperature control element ensures that the plate is kept within the working temperature range. After passing through the temperature control element, the plate enters the finishing section for finishing rolling, realizing continuous processing of the plate. The plate is temperature controlled online, shortening the processing time and improving production efficiency. Multiple precision-rolled parts can be set on one side of the precision-rolled parts on the base, and temperature control devices can be set between adjacent precision-rolled parts to adapt to the processing requirements of plates of different thicknesses.

The first and second gears mesh, as do the second and third gears. Two first cooling screws are symmetrically mounted on either side of the first gear, with opposite thread directions. Similarly, two second cooling screws are symmetrically mounted on either side of the second gear, with opposite thread directions. Finally, two third cooling screws are symmetrically mounted on either side of the third gear, with opposite thread directions. The lengths of the first, second, and third cooling screws gradually increase, as do the pitches of the first, second, and third cooling screws. Each of the first, second, and third cooling screws is equipped with a cooling slider. Each cooling slider has a fitting groove and a fitting block on both sides. The fitting block on the second cooling screw slides into the fitting groove on the first cooling screw, and the fitting block on the third cooling screw slides into the fitting groove on the second cooling screw. The cooling slider on the third cooling screw is connected to the sliding plate via a connecting rod. A strip-shaped air-cooling component is installed below each cooling slider.

[0010] As a preferred technical solution, the cleaning component includes a mounting bracket, a cleaning frame, a nozzle, and a pressure pump; A mounting frame is installed on the base on the side of the rough rolled workpiece away from the finish rolled workpiece. A cleaning frame is installed on the mounting frame, and multiple nozzles are installed on the cleaning frame. The multiple nozzles are distributed along the inner wall of the cleaning frame, and the outlets of the nozzles face away from the rough rolled workpiece.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Figures 1-8 As shown, the present invention provides a technical solution for a continuous rolling mill for titanium alloy plates. The continuous rolling mill for titanium alloy plates includes a base 1, on which a roughing section 32 and a finishing section 33 are disposed. A temperature control device is disposed between the roughing section 32 and the finishing section 33. A cleaning component is disposed on the side of the roughing section 32 away from the finishing section 33. The temperature control unit includes a heating element, a cooling element, a first mounting plate 4, and an infrared thermometer 2. The first mounting plate 4 is installed on the roughing section 32 near the finishing section 33. Multiple infrared thermometers 2 are installed on the first mounting plate 4, and the multiple infrared thermometers 2 are arranged linearly. The base 1 is provided with a heating element and a cooling element. The heating element includes a U-shaped coil 3, which is mounted on the base 1. The infrared thermometer 2 controls the operation of the U-shaped coil 3 and the cooling element, so that the temperature control keeps the plate within the processing temperature range. The excess heat from the heating element is used to improve the cleaning quality of the cleaning element.

[0023] When titanium alloy sheets need to be rolled, the heated sheet is fed into the roughing mill 32. The sheet undergoes preliminary rolling in the roughing mill 32. The sheet will cool down due to heat dissipation and heat conduction by the pressure rollers. At this time, the heating element heats the area with a temperature lower than the working temperature to ensure that the sheet is within the working temperature range. At the same time, the sheet may also heat up due to deformation during rolling. At this time, the cooling element can cool the area with a temperature higher than the working temperature. Overall, the temperature control system ensures that the sheet is kept within the working temperature range. After passing through the temperature control system, the sheet enters the finishing mill 33 for finishing rolling, realizing continuous processing of the sheet and online temperature control of the sheet to improve production efficiency. Multiple precision-rolled parts 33 can be set on one side of the precision-rolled part 33 on the base 1, and temperature control devices can be set between adjacent precision-rolled parts 33 to adapt to the processing requirements of plates of different thicknesses.

[0024] The heating element includes a sliding plate 5, a U-shaped coil 3, and external coil wiring 6; Two slide plates 5 are symmetrically arranged on the base 1 between the rough rolled piece 32 and the finish rolled piece 33. A U-shaped coil 3 is installed on the side of the two slide plates 5 near the plate. The opening of the U-shaped coil 3 faces the plate and the plate is located in the middle of the opening. The slide plate 5 is provided with an external coil wire 6. The infrared thermometer 2 is connected to a control terminal. The control terminal is connected to the external coil wire 6 and controls the current in the U-shaped coil 3.

[0025] After the sheet material is output from the roughing mill 32, the infrared thermometer 2 will detect the temperature of the sheet material surface. Multiple infrared thermometers 2 arranged linearly can detect the temperature at different positions of the same cross section of the sheet material and transmit the detection results back to the control terminal. The control terminal controls the alternating current to the U-shaped coil 3 based on the detection results and the processing temperature window of the sheet material. The sheet material is heated by electromagnetic induction, the temperature of the sheet material is precisely controlled, and the rolling quality of the sheet material is improved.

[0026] The heating element also includes a slide 7, a dual-axis motor 8, a heating screw 9, and a heating slider 10; A slide groove 7 is installed on the base 1, and a dual-axis motor 8 is installed in the slide groove 7. Heating screws 9 are installed on both output shafts of the dual-axis motor 8. The slide plate 5 is slidably installed in the slide groove 7. Heating sliders 10 are installed on the two slide plates 5. The two heating sliders 10 cooperate with the two heating screws 9 respectively. The control terminal controls the operation of the dual-axis motor 8.

[0027] After an alternating current is applied to the U-shaped coil 3, the surface of the sheet material cuts the alternating magnetic lines of force, generating eddy currents that heat the sheet material. Therefore, the parts of the sheet material coupled with the U-shaped coil 3 will be heated. The middle part of the heat dissipation wall on both sides of the sheet material dissipates heat quickly. During heating, the sheet material near the center may be heated beyond the upper limit of the temperature window, while the temperature of the side parts may be lower than the lower limit of the temperature window. Therefore, when the control terminal receives the temperature data from the infrared thermometer 2, it will control the dual-axis motor 8 to operate according to the temperature difference at different locations. The dual-axis motor 8 drives the heating screw 9 to rotate. The heating screw 9 drives the slide plate 5 through the thread engagement, causing the U-shaped coil 3 to slide along the slide groove 7, changing the overlap surface between the U-shaped coil 3 and the sheet material, ensuring that the entire sheet material is within the processing temperature window, and further ensuring the rolling quality.

[0028] The cooling components include a crossbar 11, a mounting rod 12, and a strip-shaped air-cooling component 13; A crossbar 11 is installed on the base 1, an mounting rod 12 is installed on the crossbar 11, a strip-shaped air-cooled component 13 is installed on the mounting rod 12, and an external air cooler is connected to the strip-shaped air-cooled component 13.

[0029] The sheet metal undergoes preliminary rolling on the roughing section 32. The sheet metal will cool down due to heat dissipation and heat conduction of the pressure rollers. At this time, the heating element heats the area with a temperature lower than the working temperature to ensure that the sheet metal is within the working temperature range. At the same time, the sheet metal may also increase in temperature due to deformation during rolling. At this time, the cooling element can cool down the area with a temperature higher than the working temperature. The control end controls the air cooler to provide cold air to the strip air cooling element 13 based on the temperature detection results, and blows the cold air onto the sheet metal to cool it down.

[0030] The cooling components also include a gear compartment 14, a first gear 15, a second gear 16, a third gear 17, a first cooling screw 18, a second cooling screw 19, a third cooling screw 20, a cooling slider 21, a fitting groove 22, a fitting block 23, and a connecting rod 24. A gear compartment 14 is provided inside the mounting rod 12. A first gear 15, a second gear 16, and a third gear 17 are rotatably mounted inside the gear compartment 14. The first gear 15 meshes with the second gear 16, and the second gear 16 meshes with the third gear 17. Two first cooling screws 18 are symmetrically mounted on both sides of the first gear 15, with opposite thread directions. Two second cooling screws 19 are symmetrically mounted on both sides of the second gear 16, with opposite thread directions. Two third cooling screws 20 are symmetrically mounted on both sides of the third gear 17, with opposite thread directions. The first cooling screws 18, the second cooling screws 19, and the third cooling screws... The length of the first cooling screw 18, the second cooling screw 19, and the third cooling screw 20 gradually increases. Cooling sliders 21 are installed on the first cooling screw 18, the second cooling screw 19, and the third cooling screw 20. Fitting grooves 22 and fitting blocks 23 are respectively provided on both sides of the cooling slider 21. The fitting block 23 on the second cooling screw 19 slides in engagement with the fitting groove 22 on the first cooling screw 18. The fitting block 23 on the third cooling screw 20 slides in engagement with the fitting groove 22 on the second cooling screw 19. The cooling slider 21 on the third cooling screw 20 is connected to the slide plate 5 through a connecting rod 24. Strip-shaped air-cooling components 13 are installed below the cooling slider 21.

[0031] Heating and cooling of the sheet material need to be adjusted in real time according to its surface temperature. Therefore, the required cooling width will vary depending on the situation. When the overall temperature is low and the area requiring cooling widens (i.e., the area requiring heating decreases or is no longer needed), the dual-axis motor 8 controls the slide plate 5 to move outward. As the slide plate 5 moves, it drives the cooling slider 21 on the third cooling screw 20 to slide synchronously via the connecting rod 24. Since the cooling slider 21 is threadedly engaged with the third cooling screw 20, the cooling slider 21 drives the third cooling screw to rotate. The rotation of the third cooling screw 20 drives the third gear 1. 7. When the third gear 17 rotates, it drives the second gear 16 and the first gear 15 to rotate through gear meshing. The rotation of the second gear 16 and the first gear 15 will drive the second cooling screw 19 and the third cooling screw 20 to rotate. The limiting of the interlocking block 23 and the interlocking groove 22 prevents the cooling slider 21 from rotating. Therefore, as the second cooling screw 19 and the third cooling screw 20 rotate, the cooling slider 21 moves outward along the second cooling screw 19 and the third cooling screw 20, so that the strip-shaped air-cooling component 13 connected below the cooling slider 21 is evenly distributed above the area that needs to be cooled. The two cooling screws on the same gear have the same pitch but opposite thread directions, ensuring that the two strip-shaped cooling components on the same gear move outward or inward simultaneously, thus guaranteeing uniform cooling. The first gear 15, the second gear 16, and the third gear 17 have the same specifications, while the lengths of the first cooling screw 18, the second cooling screw 19, and the third cooling screw 20 gradually increase, as do their pitches. At this point, the gears rotate the same number of times, and the spacing ratio between adjacent sliders on the same side is the same as the pitch ratio between the screws. This allows for different cooling intensities in different areas, further ensuring uniform cooling of the sheet metal, improving temperature control, and ultimately enhancing the rolling quality.

[0032] The cleaning components include a mounting bracket 25, a cleaning frame 26, a nozzle 27, and a pressure pump 28; A mounting frame 25 is installed on the base 1 on the side of the roughing workpiece 32 away from the finishing workpiece 33. A cleaning frame 26 is installed on the mounting frame 25. Multiple nozzles 27 are installed on the cleaning frame 26. The multiple nozzles 27 are distributed along the inner wall of the cleaning frame 26. The outlet of the nozzles 27 faces the side away from the roughing workpiece 32. A pressure pump 28 is connected to the outside of the cleaning frame 26 to provide gas to the nozzles 27.

[0033] During the rolling process, high-pressure gas is delivered through the pressurizing pump 28 and the nozzle 27 to clean the debris generated on the surface of the board due to oxidation, thereby improving the processing quality of the board.

[0034] A connecting frame 29 is installed on the skateboard 5, and an air inlet pipe 30 is installed on the connecting frame 29. Part of the air inlet pipe 30 is located inside the U-shaped coil 3. The part of the air inlet pipe 30 inside the U-shaped coil 3 is a metal pipe 31. The end of the air inlet pipe 30 is connected to the inlet end of the pressure pump 28.

[0035] When cleaning oxides, if the gas temperature is too low, it will continue to oxidize the surface of the board. At the same time, when the coupling area between the U-shaped coil 3 and the board decreases, the excess electromagnetic field will be wasted. At this time, the gas input to the pressurization pump 28 passes through the metal pipe 31, and the metal pipe 31 electromagnetically heats the gas through the U-shaped coil 3, which reduces the oxidation of the board and reduces energy waste.

[0036] The U-shaped coil 3 is flared, and the opening of the U-shaped coil 3 gradually widens from the slide plate 5 towards the board.

[0037] The relationship between the distance between the coil and the plate during electromagnetic heating and the heating efficiency is as follows: the smaller the distance, the higher the efficiency; the larger the distance, the lower the efficiency. Based on the principle that heat dissipation is faster at the edge of the sheet than in the middle, the opening of the U-shaped coil 3 is gradually widened from the slide plate 5 towards the sheet. When the U-shaped coil 3 performs electromagnetic heating, the heating efficiency is low near the middle and high at the edge, which can ensure the overall uniformity of the sheet temperature and avoid the phenomenon that some areas are outside the processing temperature window, thus further improving the rolling quality.

[0038] Working principle of the invention: When titanium alloy sheets need to be rolled, the heated sheet is fed into the roughing mill 32. The sheet undergoes preliminary rolling in the roughing mill 32. The sheet will cool down due to heat dissipation and heat conduction by the pressure rollers. At this time, the heating element heats the area with a temperature lower than the working temperature to ensure that the sheet is within the working temperature range. At the same time, the sheet may also heat up due to deformation during rolling. At this time, the cooling element can cool the area with a temperature higher than the working temperature. Overall, the temperature control system ensures that the sheet is kept within the working temperature range. After passing through the temperature control system, the sheet enters the finishing mill 33 for finishing rolling, realizing continuous processing of the sheet and online temperature control of the sheet to improve production efficiency. Multiple precision-rolled parts 33 can be set on one side of the precision-rolled part 33 on the base 1, and temperature control devices can be set between adjacent precision-rolled parts 33 to adapt to the processing requirements of plates of different thicknesses.

[0039] After an alternating current is applied to the U-shaped coil 3, the surface of the sheet material cuts the alternating magnetic lines of force, generating eddy currents that heat the sheet material. Therefore, the parts of the sheet material coupled with the U-shaped coil 3 will be heated. The middle part of the heat dissipation wall on both sides of the sheet material dissipates heat quickly. During heating, the sheet material near the center may be heated beyond the upper limit of the temperature window, while the temperature of the side parts may be lower than the lower limit of the temperature window. Therefore, when the control terminal receives the temperature data from the infrared thermometer 2, it will control the dual-axis motor 8 to operate according to the temperature difference at different locations. The dual-axis motor 8 drives the heating screw 9 to rotate. The heating screw 9 drives the slide plate 5 through the thread engagement, causing the U-shaped coil 3 to slide along the slide groove 7, changing the overlap surface between the U-shaped coil 3 and the sheet material, ensuring that the entire sheet material is within the processing temperature window, and further ensuring the rolling quality.

[0040] The U-shaped coil 3 is flared, and the opening of the U-shaped coil 3 gradually widens from the slide plate 5 towards the board.

[0041] The relationship between the distance between the coil and the plate during electromagnetic heating and the heating efficiency is as follows: the smaller the distance, the higher the efficiency; the larger the distance, the lower the efficiency. Based on the principle that heat dissipation is faster at the edge of the sheet than in the middle, the opening of the U-shaped coil 3 is gradually widened from the slide plate 5 towards the sheet. When the U-shaped coil 3 performs electromagnetic heating, the heating efficiency is low near the middle and high at the edge, which can ensure the overall uniformity of the sheet temperature and avoid the phenomenon that some areas are outside the processing temperature window, thus further improving the rolling quality.

[0042] Heating and cooling of the sheet material need to be adjusted in real time according to its surface temperature. Therefore, the required cooling width will vary depending on the situation. When the overall temperature is low and the area requiring cooling widens (i.e., the area requiring heating decreases or is no longer needed), the dual-axis motor 8 controls the slide plate 5 to move outward. As the slide plate 5 moves, it drives the cooling slider 21 on the third cooling screw 20 to slide synchronously via the connecting rod 24. Since the cooling slider 21 is threadedly engaged with the third cooling screw 20, the cooling slider 21 drives the third cooling screw to rotate. The rotation of the third cooling screw 20 drives the third gear 1. 7. When the third gear 17 rotates, it drives the second gear 16 and the first gear 15 to rotate through gear meshing. The rotation of the second gear 16 and the first gear 15 will drive the second cooling screw 19 and the third cooling screw 20 to rotate. The limiting of the interlocking block 23 and the interlocking groove 22 prevents the cooling slider 21 from rotating. Therefore, as the second cooling screw 19 and the third cooling screw 20 rotate, the cooling slider 21 moves outward along the second cooling screw 19 and the third cooling screw 20, so that the strip-shaped air-cooling component 13 connected below the cooling slider 21 is evenly distributed above the area that needs to be cooled. The two cooling screws on the same gear have the same pitch but opposite thread directions, ensuring that the two strip-shaped cooling components on the same gear move outward or inward simultaneously, thus guaranteeing uniform cooling. The first gear 15, the second gear 16, and the third gear 17 have the same specifications, while the lengths of the first cooling screw 18, the second cooling screw 19, and the third cooling screw 20 gradually increase, as do their pitches. At this point, the gears rotate the same number of times, and the spacing ratio between adjacent sliders on the same side is the same as the pitch ratio between the screws. This allows for different cooling intensities in different areas, further ensuring uniform cooling of the sheet metal, improving temperature control, and ultimately enhancing the rolling quality.
