Description

TECHNICAL FIELD

[0001] The present application relates to the alloy processing technical field, specifically, a kind of manganese copper precision resistance alloy processing equipment. BACKGROUND

[0002] In the processing flow of manganese copper precision resistance alloy, cold rolling is a crucial process, which is to roll the strip after solid solution treatment to the target thickness, and to accumulate energy through plastic deformation to provide driving force for subsequent recrystallization heat treatment. The uniformity of the cold rolling process directly determines the uniformity of the microstructure of the alloy, the distribution of internal residual stress and the flatness quality. Non-uniform deformation will lead to uneven grain size and texture deviation during subsequent recrystallization, ultimately affecting the stability of resistance value and temperature coefficient.

[0003] The existing cold rolling mill is usually equipped with a traditional rolling oil lubrication system, which sprays rolling oil to the roll and strip surface through a row of simple nozzles to achieve lubrication, cooling and cleaning. The current lubrication system has a simple oil path structure, and there is a slight difference in the outlet pressure of each nozzle, which leads to uneven oil film thickness on the surface of the roll, making the friction coefficient of the strip in the width direction of the roll inconsistent, causing uneven thickness and uneven microstructure in the transverse direction. The lubrication system uses centralized oil supply, which is difficult to achieve local lubrication control, especially in the edge position of the strip, where the stress is concentrated and the heat is dissipated quickly, which is a high-risk area for cracks and warping. The traditional lubrication system is difficult to provide differentiated lubrication conditions for the edge area. During rolling, the oil adheres to the surface of the roll. With the rotation of the roll and the continuous injection of oil, the difference in oil film thickness in the width direction of the roll gradually increases, further expanding the uneven thickness of the cold rolling. SUMMARY

[0004] The present application provides a manganese copper precision resistance alloy processing equipment to solve the problem of uneven friction coefficient of the strip in the width direction of the roll caused by the difficulty of local lubrication control of the existing lubrication system and the accumulation of oil on the surface of the roll, which leads to uneven thickness of the strip in the transverse direction and reduces the quality of cold rolling.

[0014] In order to reduce the temperature deformation of the roller after long-time rolling, rotating shafts are fixedly connected to both ends of the roller, the rotating shafts are rotatably arranged on the machine base, the rotating shafts and the roller are hollow structures, the roller and the rotating shafts are communicated, one of the rotating shafts is communicated with the spray beam, and the other rotating shaft is communicated with an oil supply pipe for supplying oil.

[0015] In order to improve the cleaning effect of the roller, an oil absorption pad is arranged at the inlet of the negative pressure air knife, and the oil absorption pad is in contact with the roller.

[0016] In order to increase the strength of the roller, a filler block is arranged in the roller, and a plurality of support plates are fixedly connected between the filler block and the inner wall of the roller.

The sponge pad and the filter drawer block the debris to filter the oil, which is convenient for recycling the oil. The airflow generated by the vacuum pump supplies air to the air supply pipe, and the precision valve accurately controls the air supply quantity. The part after rolling is cleaned to reduce the residue of the oil on the surface of the roller, thereby reducing the unevenness of the lubricating oil on the surface of the roller caused by the accumulation of the oil film, and reducing the scratches of the strip and the roller caused by the debris residue.

[0038] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments of the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0039] As Figures 1 to 11As shown in the figure, this embodiment proposes a processing equipment for manganese copper precision resistance alloy, including a machine base 1 and a roller 2. The roller 2 is rotatably mounted on the machine base 1. It also includes a spray beam 3, a micro nozzle 7, a negative pressure suction system and a measuring component.

[0040] like Figures 1 to 6 As shown, the spray beam 3 is connected to an oil inlet pipe 4, and an oil inlet valve 5 is installed on the oil inlet pipe 4. A level gauge 6 is installed on the spray beam 3. The spray beam 3 corresponds one-to-one with the roll 2. The spray beam 3 is located on the side of the roll 2 where it enters the strip. Multiple micro-nozzles 7 are provided. The micro-nozzles 7 are connected to the spray beam 3 through an oil supply pipe 8. The multiple micro-nozzles 7 are equidistantly arranged on the spray beam 3. The micro-nozzles 7 are connected to an air supply pipe 9, and a precision valve 10 is installed on the air supply pipe 9. The micro-nozzles 7 have an outlet for spraying oil into the roll 2. The oil inlet pipe 4 supplies oil to the inside of the spray beam 3. The lubricating oil is supplied to the nozzle. The level gauge 6 can be a float-type level gauge or a radar level gauge to monitor the oil level within the spray beam 3. The level gauge 6 can send an electrical signal to the central controller to control the opening and closing of the oil inlet valve 5, ensuring timely oil supply to the spray beam 3 and preventing insufficient lubricating oil. Simultaneously, when the oil level reaches a certain point, the oil inlet pipe 4 is closed to stop oil supply, preventing excessive oil in the spray beam 3 from creating high pressure that could cause lubricating oil to directly enter the micro-nozzle 7, thus reducing the workload of the oil pump. The effect of pressure on the injection volume is mainly controlled in this embodiment by adjusting the air supply pressure through the air supply pipe 9. The outlet diameter of the micro-nozzle 7 is extremely small, ranging from 0.1 to 0.5 mm. The precision valve 10 can be controlled by a piezoelectric ceramic actuator, and the valve core opening can be precisely adjusted within milliseconds. High-pressure air enters the interior of the micro-nozzle 7 from the air supply pipe 9 and is ejected, creating a negative pressure environment within the micro-nozzle 7. Through the negative pressure generated between the micro-nozzle 7 and the oil supply pipe 8, the lubricating oil is drawn upwards. The oil impacts the septum inside the micro-nozzle 7, turning into an extremely fine mist that is sprayed outward. The piezoelectric ceramic brake has an extremely fast response speed, allowing for high-frequency pulse-type adjustment of the oil volume, achieving "droplet-level" control. By controlling the valve core opening degree and opening time of the precision valve 10, the amount of oil sprayed onto the surface of the roll 2 by each micro-nozzle 7 can be precisely controlled, achieving zoned control of the oil film on the surface of the roll 2. Multiple micro-nozzles 7 form a dense array, similar to "inkjet printing," which can form a uniform and controllable oil film on the surface of the roll 2.

[0041] like Figures 1 to 10As shown, the negative pressure suction system is arranged on one side of the strip discharging side of the roller 2, and is used to remove the oil liquid remaining on the surface of the roller 2 after rolling. The outlet of the negative pressure suction system is communicated with the air supply pipe 9. The negative pressure suction system comprises a negative pressure air knife 101, and the negative pressure air knife 101 and the roller 2 are in one-to-one correspondence. The negative pressure air knife 101 is communicated with a vacuum pump 102. The outlet of the vacuum pump 102 is communicated with an exhaust pipe 103. A pressure relief member is arranged at the outlet of the exhaust pipe 103. The air supply pipe 9 and the exhaust pipe 103 are communicated. The pressure relief member comprises a baffle 201. The baffle 201 is connected with the exhaust pipe 103 through a compression spring 202. The compression spring 202 presses the baffle 201 against the outlet of the exhaust pipe 103. A fixed plate 203 is fixedly connected inside the exhaust pipe 103. The baffle 201 is connected with the fixed plate 203 through the compression spring 202 and an extension rod. The baffle 201 is in contact with the outlet of the exhaust pipe 103. The negative pressure air knife 101 is suctioned by the vacuum pump 102. The inlet of the negative pressure air knife 101 is relatively narrow. A large negative pressure environment is formed at the inlet, so that the oil liquid and metal scraps on the surface of the roller 2 can be sucked into the negative pressure air knife 101. In order to improve the cleaning effect of the roller 2, an oil absorption pad 11 is arranged at the inlet of the negative pressure air knife 101. The oil absorption pad 11 is in contact with the roller 2. The oil absorption pad 11 can absorb the oil liquid on the surface of the roller 2 and block the metal scraps, so that the negative pressure air knife 101 can clean the roller 2 completely. The oil absorption pad 11 can scrape off the residual oil liquid and metal scraps on the surface of the roller 2, which can in turn promote the negative pressure air knife 101 to suck the oil liquid and metal scraps. The oil absorption pad 11 is located on the side away from the other negative pressure air knife 101, that is, on the side along the rotating direction of the roller 2. The oil absorption pad 11 can block the oil liquid and metal scraps at the inlet of the negative pressure air knife 101, so that the negative pressure air knife 101 can suck the oil liquid and metal scraps. In order to recycle the oil liquid, a recycling box 12 is arranged. The outlet of the vacuum pump 102 and the negative pressure air knife 101 are communicated with the top of the recycling box 12. A recycling opening is arranged on the recycling box 12. A filter drawer 13 is sealingly and slidably arranged at the recycling opening. A sponge pad 14 is arranged in the filter drawer 13. The inside of the recycling box 12 forms a negative pressure environment by the vacuum pump 102. The outlet of the vacuum pump 102 and the top of the recycling box 12 are communicated, so that the oil liquid is not sucked into the vacuum pump 102. The negative pressure air knife 101 is communicated with the recycling box 12 through a suction pipe 15. A partition plate 16 is arranged between the outlet of the suction pipe 15 and the communication position of the recycling box 12 and the vacuum pump 102, so that the metal scraps are not sucked into the vacuum pump 102. Under the action of negative pressure, the metal scraps and lubricating oil liquid in the negative pressure air knife 101 enter the inside of the recycling box 12. The sponge pad 14 absorbs the lubricating oil liquid and filters the lubricating oil liquid. After the sponge pad 14 absorbs a certain amount of lubricating oil liquid, the sponge pad 14 is saturated. The lubricating oil liquid drops to the bottom of the recycling box 12. A liquid discharge pipe 17 is communicated with the bottom of the recycling box 12, so that the lubricating oil liquid can be recycled. After a certain period of time, the filter drawer 13 is taken out from the inside of the recycling box 12.The inside of the sponge pad 14 can be cleaned, and the lubricating oil liquid in the sponge pad 14 can be squeezed out and recycled. The gas discharged by the vacuum pump 102 enters the inside of the gas supply pipe 9 to supply gas to the gas supply pipe 9. The gas inlet amount of each gas supply pipe 9 is adjusted by the precision valve 10. The baffle 201 is closed to the exhaust pipe 103 under the action of the compression spring 202, so as to ensure that the gas discharged by the vacuum pump 102 enters the inside of the gas supply pipe 9 to supply gas for the ejection of the oil liquid. When the gas outlet amount of the vacuum pump 102 is too large and exceeds the required amount of the gas supply pipe 9, the pressure in the exhaust pipe 103 increases, the baffle 201 can be pushed open, and the normal exhaust of the vacuum pump 102 is ensured.

[0042] As shown in Figures 1 to 2 The measuring element is arranged on one side of the roll 2 discharging the strip, and is used for detecting the plate shape and the transverse thickness distribution of the strip and adjusting the gas amount of the gas supply pipe 9 to adjust the oil ejection amount. The measuring element includes a laser plate shape meter 301 and a thickness gauge 302. The laser plate shape meter 301 is used for detecting the plate shape of the strip, and the thickness gauge 302 is used for detecting the transverse thickness of the strip. The laser plate shape meter 301 and the thickness gauge 302 can transmit signals to the central controller in real time and adjust the opening and closing amount of the precision valve 10 on the gas supply pipe 9 to adjust the oil ejection amount. The laser plate shape meter 301 is a plurality of straight-line lasers installed obliquely along the rolling direction and the strip width direction of the plate strip. Laser irradiation forms a linear shape on the surface of the plate strip. The linear laser shape is extracted and calculated and analyzed by a digital image processing technology, and finally the plate shape information of the plate strip is obtained. The thickness gauge 302 can use an isotope thickness gauge 302. The isotope thickness gauge 302 can measure the thickness of metal materials by using the principle that different substances have different absorption and scattering of radiation. Common isotopes include gamma rays and beta rays. The laser plate shape meter 301 and the thickness gauge 302 are installed as close to the roll 2 as possible to reduce the lag adjustment time of the plate shape and the plate thickness. The plate shape and the thickness of the strip after rolling by the roll 2 are monitored by the laser plate shape meter 301 and the thickness gauge 302. The central controller has a pre-stored lubrication model. When the laser plate shape meter 301 detects that waves appear in the middle of the strip, the system determines that the lubrication in this area is excessive, and then adjusts the precision valve 10 at the corresponding position, that is, the middle position of the plurality of gas supply pipes 9, to reduce the gas outlet amount and thus reduce the oil ejection amount, increase the friction between the roll 2 and the strip, and thus flatten the strip. Conversely, if waves appear at the edge position, the oil supply at the corresponding edge position is reduced, and real-time, active and zoned lubrication control based on plate and thickness feedback is realized.
