Description

Technical Field

[0002] Nonferrous metals are basic materials for the development of the national economy, especially copper, which is used in most industries such as aviation, aerospace, automobiles, machinery manufacturing, and construction. Most metals undergo calendering during processing. Calendering is a forming processing method that uses the pressure generated by the gap between rollers to stretch the metal into a film or sheet under the action of pressure.

[0003] However, for common copper materials, such as red copper (T1, T2, T3, etc.), the rolling temperature is usually controlled within a certain range to ensure good processing performance and material quality. Generally speaking, the rolling temperature should be lower than the recrystallization temperature of copper to avoid recrystallization of the material during processing and resulting in performance degradation. At the same time, the temperature should not be too low to avoid the copper material being too hard and increasing the difficulty of processing. Therefore, in order to facilitate maintaining a certain temperature during the rolling process, the existing rolling device does not have a certain heating function, which will increase the difficulty of rolling and affect the efficiency and quality of rolling.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figure 1 - Fig. 9As shown, the non-ferrous metal rolling device provided in this embodiment includes an upper rolling roller 1 and a lower rolling roller 2 which are vertically arranged. The upper rolling roller 1 is connected to an upper pressing bracket 6 through an upper rolling roller transmission shaft 101, and the lower rolling roller 2 is connected to a lower fixed bracket 7 through a lower rolling roller transmission shaft 201. The upper pressing bracket 6 is rotatably connected to one end of the lower fixed bracket 7. The upper rolling roller 1 is arranged directly above the lower rolling roller 2. When the upper pressing bracket 6 moves the upper rolling roller 1 downward, the upper rolling roller 1 and the lower rolling roller 2 approach and roll the non-ferrous metal. The upper rolling roller 1 is arranged above the lower rolling roller 2, and the upper rolling roller 1 can move correspondingly relative to the lower rolling roller 2 through the upper pressing bracket 6, thereby changing the positional relationship between the upper rolling roller 1 and the lower rolling roller 2. That is to say, when the upper pressing bracket 6 is rotated downward, the non-ferrous metal on the lower rolling roller 2 can be rolled, which has high flexibility and the scope of use will also increase accordingly. For common copper materials, such as red copper (T1, T2, T3, etc.), the rolling temperature is usually controlled within a certain range to ensure good processing performance and material quality. Generally speaking, the rolling temperature should be lower than the recrystallization temperature of copper to avoid the material from recrystallizing during processing and causing performance degradation. At the same time, the temperature should not be too low to avoid the copper material being too hard and increasing the processing difficulty. Therefore, in order to maintain a certain temperature during the rolling process, a heating mechanism 3 is fixedly provided on the upper rolling roller 1 and the lower rolling roller 2. The heating mechanism 3 includes an electrical connection ring 301 and an electrical contact 302. The two electrical connection rings 301 are connected to each other. A plurality of heating rods 307 are arranged in parallel, an electrical connection chamber 304 is provided on the inner side of the electrical connection ring 301, a movable metal connection sheet 305 is fixedly arranged inside the electrical connection chamber 304, one end of the electrical contact 302 is connected to a fixed metal connection sheet 306, the movable metal connection sheet 305 abuts against and is electrically connected to the fixed metal connection sheet 306, a heating mechanism 3 is fixedly arranged on both the upper calendering roller 1 and the lower calendering roller 2, the upper calendering roller 1 and the lower calendering roller 2 are heated simultaneously by the heating rods 307 on the heating mechanism 3, so as to ensure the uniformity of heating and improve the heating efficiency during the calendering process; A movable metal connecting piece 305 is fixedly arranged inside the electrical connecting ring 301 on the heating mechanism 3, and a fixed metal connecting piece 306 is fixedly arranged on the electrical contact 302, that is, the upper calendering roller 1 and the lower calendering roller 2 can also be heated while the upper calendering roller 1 is rotating, breaking the limitation of the traditional method of heating before calendering, achieving the purpose of simultaneous heating and calendering, and greatly improving the calendering efficiency; At the same time, during the heating process, in order to avoid a short circuit between the heating rod 307 and the upper calendering roller 1 or the lower calendering roller 2, because the pressing plate is usually a steel plate, a plurality of heating holes 102 are opened inside the upper calendering roller 1 and the lower calendering roller 2, and the heating rod 307 is inserted into the interior of the heating hole 102, and a ceramic ring 308 is fixedly provided on the outer side of the heating rod 307, and the ceramic ring 308 is against the interior of the heating hole 102, so the ceramic ring 308 is fixedly provided inside the heating hole 102, and the heating rod 307 is fixedly provided inside the ceramic ring 308, which, on the one hand, plays an insulating role to prevent the heating rod 307 from short circuiting, and on the other hand, the ceramic ring 308 has good thermal conductivity, and can evenly transfer heat to the upper calendering roller 1 or the lower calendering roller 2, thereby improving the calendering efficiency and calendering quality; One end of the lower calendering roller transmission shaft 201 is connected to a driven gear 202, a rotating motor 9 is provided at the bottom of the driven gear 202, and a driving gear 901 is provided at the output end of the rotating motor 9, the driving gear 901 is meshed and connected with the driven gear 202, and the driving gear 901 is used to rotate the driven gear 202, and the lower calendering roller 2 is driven to rotate by the driving gear 901 on the rotating motor 9, and the upper calendering roller 1 is driven to rotate under the action of resistance, so as to facilitate the calendering of non-ferrous metals and improve the calendering efficiency. A motor fixing plate 706 is fixedly connected to the lower fixed bracket 7, and the rotating motor 9 is fixedly arranged on the motor fixing plate 706. The rotating motor 9 is fixedly arranged on the motor fixing plate 706, and the structure is simple, which improves the stability of the rotating motor 9; The lower fixed bracket 7 is connected to the support plate 10 through the rear transmission plate fixing block 704 or the front transmission plate fixing block 705. The height of the upper side of the support plate 10 is lower than the height of the upper side of the lower calendering roller 2. A preheating coil 11 is fixedly arranged at the bottom of the support plate 10. The preheating coil 11 is used to heat the support plate 10. The non-ferrous metal is supported by the support plate 10 to improve the stability of the non-ferrous metal. Moreover, the support plate 10 is heated by the preheating coil 11 to preheat the non-ferrous metal in advance, thereby improving the quality and efficiency of calendering. In addition, too high temperature will also affect the quality of calendering. Therefore, once the temperature of the upper calendering roller 1 or the lower calendering roller 2 is too high, heat dissipation is required. A cooling structure 4 is fixedly provided at both ends of the upper calendering roller 1 and the lower calendering roller 2. The cooling structure 4 includes an air supply plate 401 and an exhaust plate 402. The electrical contact 302 is fixedly provided on the cooling structure 4. A cooling structure 4 is fixedly provided at both ends of the upper calendering roller 1 or the lower calendering roller 2. A plurality of corresponding through holes 403 are provided on the air supply plate 401 and the exhaust plate 402. A heat dissipation fan fixing plate 5 is fixedly provided inside the through hole 403 on the air supply plate 401. The heat dissipation fan fixing plate 5 is provided on the heat dissipation fan fixing plate 5. A heat dissipation fan 501 is fixedly installed, and metal grilles 408 are fixedly installed at the ports of the through holes 403 of the air supply plate 401 and the exhaust plate 402. The heat dissipation fan 501 is fixedly installed inside the through holes 403. After the heat dissipation fan 501 is started, the airflow passes through the upper calendering roller 1 or the lower calendering roller 2, and then is discharged from the exhaust plate 402. Therefore, the temperature of the upper calendering roller 1 or the lower calendering roller 2 can be reduced to avoid the upper calendering roller 1 or the lower calendering roller 2 from being too high in temperature, which affects the quality and efficiency of calendering. The metal grille 408 can prevent dust from entering the upper calendering roller 1 or the lower calendering roller 2, thereby improving the service life of the device.

[0025] Further, such as Figure 5 and Figure 6 As shown, a C-fixed connection block 404 is fixedly provided on both the air supply plate 401 and the air exhaust plate 402, the electrical contact 302 is fixedly provided on the C-fixed connection block 404 through a contact connection rod 303, a T-shaped fixing block 405 is fixedly connected to the C-fixed connection block 404, the T-shaped fixing block 405 is fixedly provided on the upper pressure bracket 6 or the lower fixed bracket 7 through a welding block 406, the electrical contact 302 is fixedly provided on the C-fixed connection block 404 through the contact connection rod 303, and the C-fixed connection block 404 is fixedly provided on the upper pressure bracket 6 or the lower fixed bracket 7 through the T-shaped fixing block 405, thereby improving the stability of the temperature increasing mechanism 3 and the temperature reducing structure 4, and also ensuring that the temperature increasing mechanism 3 and the temperature reducing structure 4 move with the movement of the upper pressure bracket 6; Moreover, a transmission hole 407 is opened in the middle of the air supply plate 401 and the exhaust plate 402. The upper calendering roller transmission shaft 101 or the lower calendering roller transmission shaft 201 is rotatably set inside the transmission hole 407, which can also improve the rotation stability of the upper calendering roller 1 or the lower calendering roller 2.

[0026] Furthermore, in order to facilitate braking the upper calendering roller 1 on the upper pressure bracket 6 to adjust the distance between the upper calendering roller 1 and the lower calendering roller 2, as shown in FIG. Figure 1 , Figure 2 as well as Figure 6As shown, one end of the upper pressing bracket 6 is connected to the upper pressing bracket rotating shaft 601, and the upper pressing bracket rotating shaft 601 is rotatably set on the lower fixed bracket 7. One end of the upper pressing bracket 6 is rotatably set on the lower fixed bracket 7, and the other end shortens the distance between the upper calendering roller 1 and the lower calendering roller 2 as the height decreases. The other end of the upper pressing bracket 6 is connected to a pressing plate 602, and the pressing plate 602 is provided with symmetrically distributed guide bar through holes 603. One end of the lower fixed bracket 7 is connected to a guide bar 702 through a sliding bar fixing plate 701, and the guide bar 702 is slidably set on the guide bar Inside the through hole 603, the upper end of the guide bar 702 is connected with a hydraulic top plate 703. When the upper pressure bracket 6 moves downward, the guide bar 702 is slidably arranged inside the guide bar through hole 603 to achieve the purpose of adjusting the distance between the upper calendering roller 1 and the lower calendering roller 2. A hydraulic rod 8 is fixedly arranged on the bottom side of the hydraulic top plate 703. The bottom side of the hydraulic rod 8 abuts against the upper side of the pressure plate 602. Springs 801 are fixedly arranged on both sides of the hydraulic rod 8 on the hydraulic top plate 703. The upper side of the guide bar 702 at the bottom of the spring 801 is fixedly connected; Among them, the hydraulic rod 8 is used to push the pressure plate 602 downward. In the process of pushing the pressure plate 602 downward, the upper calendering roller 1 gradually approaches the lower calendering roller 2, thereby changing the distance between the upper calendering roller 1 and the lower calendering roller 2. When the hydraulic rod 8 stops braking, the spring 801 is used to increase the distance between the upper calendering roller 1 and the lower calendering roller 2.

[0027] In addition, if Figure 1 and Figure 2 As shown, the width of the guide bar 702 is smaller than the width of the guide bar through hole 603. When the upper calendering roller 1 moves downward, the movement trajectory of the upper pressing bracket 6 is an arc, ensuring that the guide bar 702 slides inside the guide bar through hole 603. In order to prevent the guide bar 702 from getting stuck while sliding inside the guide bar through hole 603, the aperture of the guide bar through hole 603 is larger than the outer diameter of the guide bar 702. Therefore, it can be ensured that the guide bar 702 will not get stuck inside the guide bar through hole 603 when the upper pressing bracket 6 moves in a circular motion.

[0028] Further, if Figure 8 As shown, harmful gases are generated during the calendering process. A shell 12 is fixedly provided on the outside of the upper calendering roller 1 and the lower calendering roller 2. A feeding port corresponding to the support plate 10 is provided on the shell 12. Both sides of the shell 12 are connected to a purification box 15 through an exhaust pipe 14 or an intake pipe 16. The interior of the purification box 15 is filled with lime water. The shell 12 can seal the entire device to prevent harmful gases from diffusing into the air. The alkaline lime water can absorb acidic gases and reduce the harm of harmful gases to workers. The exhaust pipe 14 corresponds to the air supply plate 401, and the air intake pipe 16 corresponds to the exhaust plate 402. The interior of the purification box 15 is connected to a hollow partition 18 through a partition support frame 17. The hollow partition 18 is fixedly provided with an exhaust fan 20 at the port of the exhaust pipe 14. An activated carbon layer 19 is provided on the upper side of the hollow partition 18 below the exhaust pipe 14. An exhaust fan 20 is fixedly provided at one end of the exhaust pipe 14. Therefore, the exhaust fan 20 can absorb the air inside the shell 12, purify the gas when it passes through the purification box 15, and then discharge it to the interior of the upper calender roller 1, that is, it can purify the air inside the shell 12 and dissipate the heat of the air inside the shell 12; An operation panel 13 is fixedly provided on the upper side of the shell 12 at one side of the purification box 15. The electrical contact 302 is electrically connected to the operation panel 13 through a copper wire 309. The operation of the entire device is controlled by the operation panel 13, which improves the convenience of use.

[0029] like Figure 1 - Fig. 9 As shown, the principle of the non-ferrous metal rolling device provided in this embodiment is as follows: The upper calendering roller 1 is arranged above the lower calendering roller 2, and the upper calendering roller 1 can move correspondingly relative to the lower calendering roller 2 through the upper pressing bracket 6, thereby changing the positional relationship between the upper calendering roller 1 and the lower calendering roller 2, that is, when the upper pressing bracket 6 is rotated downward, the non-ferrous metal on the lower calendering roller 2 can be calendered, which has high flexibility and the scope of use will also increase accordingly; a heating mechanism 3 is fixedly arranged on the upper calendering roller 1 and the lower calendering roller 2, and the upper calendering roller 1 and the lower calendering roller 2 are heated simultaneously by the heating rod 307 on the heating mechanism 3 to ensure the uniformity of heating and to improve the heating efficiency during the calendering process; A movable metal connecting piece 305 is fixedly arranged inside the electrical connecting ring 301 on the heating mechanism 3, and a fixed metal connecting piece 306 is fixedly arranged on the electrical contact 302, that is to say, the upper calendering roller 1 and the lower calendering roller 2 can also be heated while the upper calendering roller 1 is rotating, breaking the limitation of the traditional heating before calendering, and achieving the purpose of simultaneous heating and calendering. A ceramic ring 308 is fixedly arranged inside the heating hole 102, and the heating rod 307 is fixedly arranged inside the ceramic ring 308. On the one hand, it plays an insulating role to prevent the heating rod 307 from short-circuiting. On the other hand, the ceramic ring 308 has good thermal conductivity and can evenly transfer heat to the upper calendering roller 1 or the lower calendering roller 2, thereby improving the calendering efficiency and calendering quality.
