Description

Technical Field

[0001] This utility model relates to the field of copper strip production technology, specifically to a transfer case for a precision rolling leveling machine used in copper strip production. Background Technology

[0002] Copper strip production includes precision rolling and leveling, a process that uses precision rolling and leveling to achieve high-precision flatness of the copper strip. The cold rolling process, which uses a multi-roll mill to reduce the thickness and finish the surface of the copper strip, eliminates the waviness and internal stress of the rolled copper strip using a multi-roll leveler. The transfer case of the precision rolling and leveling machine is a key transmission component in metal sheet processing equipment, mainly used to distribute power to the multiple working rolls of the leveling machine for rotation.

[0003] The utility model with announcement number CN205244310U discloses a transfer case for a precision rolling leveling machine used in LED copper strip production. One end of the input shaft extends out of the housing and is connected to the power source output end outside the housing. One end of the output shaft extends out of the housing and is connected to the power input end of the precision rolling leveling machine outside the housing. The input shaft and the output shaft are parallel. A drive gear and a driven gear are respectively installed on the input shaft and the output shaft, and the drive gear and the driven gear mesh with each other.

[0004] However, the aforementioned open-source gearbox for the finishing mill leveling machine still has the following problems in actual operation: Although the drive is achieved by the meshing of the driving gear and the driven gear inside the gearbox, this type of gear meshing drive method cannot be adjusted according to the actual output requirements. Controlling only the speed of the drive motor will result in a large load on the motor, which may cause damage during long-term operation, making it difficult to adjust and operate.

[0005] Therefore, we proposed a transfer case for a precision rolling leveling machine in copper strip production to address the problems mentioned above. Summary of the Invention

[0006] The purpose of this utility model is to provide a transfer case for a precision rolling leveling machine in copper strip production. This solves the problem that existing transfer cases achieve drive by meshing a drive gear and a driven gear inside the transfer case. However, this type of gear meshing transfer method cannot be adjusted according to the actual output requirements. Furthermore, controlling only the speed of the drive motor will result in a large load on the motor, which can easily cause damage during long-term operation, making it difficult to adjust and operate.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a transfer box for a precision rolling leveling machine for copper strip production, comprising a transfer box body and a drive motor disposed at the rear of the transfer box body, wherein a drive output shaft is fixedly mounted at the front end of the drive motor;

[0008] It also includes: a transmission mechanism is provided inside the transfer case body, and the transmission mechanism includes a driving gear and a driven gear that mesh with each other, and the driving gear and the driven gear are installed inside the transfer case body for rotation from right to left;

[0009] The transfer case body has a transfer mechanism on its front side, and the transfer mechanism includes a transmission output shaft, and a transmission gear is fixedly installed on the outer wall of the middle part of the transmission output shaft.

[0010] Preferably, the transmission mechanism includes a driving shaft and a driven shaft, and the driving shaft and the driven shaft are respectively fixedly installed at the shafts of the driving gear and the driven gear inside the transfer case body.

[0011] Preferably, the transmission mechanism includes a drive shaft and a driven shaft that are rotated from right to left within the transfer case body via bearings, and the rear end of the drive shaft extends through the rear exterior of the transfer case body, and the rear end of the drive shaft is fixedly connected to the front end of the drive output shaft.

[0012] Preferably, the rear end of the transmission output shaft of the transfer mechanism is mounted through a bearing on the left side of the front of the transfer case body, and the rear end of the transmission output shaft is fixedly connected to the front end of the driven rotating shaft. The transmission output shaft drives the transmission gear on the middle outer wall to rotate.

[0013] Preferably, the transfer mechanism includes a transfer output shaft, and the rear end of the transfer output shaft is rotatably mounted on the right side of the front of the transfer housing body via a bearing, and positioning grooves are provided on both the upper and lower sides inside the transfer output shaft.

[0014] Preferably, the transfer mechanism includes a positioning bushing, which is slidably sleeved on the outer wall of the transfer output shaft. Positioning sliders are fixedly installed on both the upper and lower sides of the interior of the positioning bushing, and the positioning sliders are slidably installed in the positioning groove inside the transfer output shaft.

[0015] Preferably, the transfer mechanism includes a toggle connecting groove, which is opened on the front and rear sides of the outer side of the positioning bushing. The interior of the symmetrically opened toggle connecting grooves is engaged with the left end of the transfer fork, and the positioning bushing is driven to slide back and forth on the outer wall of the transfer output shaft by the transfer fork.

[0016] Preferably, the transfer mechanism includes a transfer gear, which is fixedly installed on the middle outer wall of the positioning bushing. In the initial state, the positioning bushing and the transfer gear are located at the front end of the transfer output shaft. When the transfer gear moves backward with the positioning bushing, it meshes with the transmission gear on the left side. Moreover, the diameter of the transfer gear is larger than the diameter of the transmission gear.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The transfer case of the precision rolling leveling machine for copper strip production drives the drive gear and driven gear inside the transfer case body to rotate through the drive motor, so as to run at normal speed through the connected transmission output shaft, and after the transfer gear meshes with the transmission gear, the running speed of the precision rolling leveling machine is reduced and adjusted. The specific details are as follows:

[0018] 1. The operation of the drive motor drives the internal drive output shaft to rotate. Simultaneously, the front end of the drive output shaft is rotatably mounted inside the transfer case body and fixedly connected to the drive shaft on the right side of the transfer case body. This allows the drive shaft to drive the drive gear and driven gear to mesh, thereby causing the driven shaft to rotate inside the transfer case body.

[0019] The transmission output shaft, which is rotatably mounted on the left side of the front of the transfer case, is fixedly connected to the driven shaft. The driven shaft drives the transmission output shaft to rotate synchronously with the external transmission gear during rotation, so that it can operate at normal speed after being connected to the finishing mill leveling machine.

[0020] 2. The positioning bushing installed on the front of the transfer case body is connected to the transfer fork that is slidably inserted through the actuation connection slots opened on the front and rear sides. When a speed change is required, the positioning bushing is slid by sliding the transfer fork backward.

[0021] Furthermore, the transfer gear, which is fixedly connected to the positioning bushing, moves synchronously to the rear of the transfer output shaft so that the transfer gear meshes with the transmission gear, causing the positioning bushing to rotate synchronously. The positioning bushing is connected to the positioning slide groove on the outside of the transfer output shaft through the internal positioning slider, thereby driving the transfer output shaft to rotate, so as to adjust the running speed of the finishing mill leveling machine.

[0030] Please see Figures 1-6 The present invention provides the following technical solution:

[0031] Example 1: In order to solve the problems of the existing set-off box of the finishing mill leveling machine in actual use, this example discloses the following technical solution: a set-off box for the finishing mill leveling machine for copper strip production, including a set-off box body 1 and a drive motor 2 located at the rear of the set-off box body 1, and a drive output shaft 3 fixedly installed at the front end of the drive motor 2; a transmission mechanism is provided inside the set-off box body 1, and the transmission mechanism includes a driving gear 4 and a driven gear 5 that mesh with each other, and the driving gear 4 and the driven gear 5 are installed inside the set-off box body 1 for rotation from right to left.

[0032] The transmission mechanism includes a driving shaft 8 and a driven shaft 9, which are respectively fixedly installed on the shafts of the driving gear 4 and the driven gear 5 inside the transfer case body 1. The driving shaft 8 and the driven shaft 9 are installed inside the transfer case body 1 by rotating from right to left through bearings. The rear end of the driving shaft 8 extends through the rear exterior of the transfer case body 1, and the rear end of the driving shaft 8 is fixedly connected to the front end of the drive output shaft 3.

[0033] like Figure 1 , Figure 4As shown, during operation, the drive motor 2 drives the drive output shaft 3 at the front end to rotate, causing the drive output shaft 3 to rotate on the right side inside the transfer case body 1, and driving the fixedly connected drive shaft 8 and the drive gear 4 in the middle to rotate. Then, the drive gear 4 drives the meshing driven gear 5 and the driven shaft 9 at the shaft to rotate, so that the driven shaft 9 drives the transmission output shaft 6 on the left side of the front of the transfer case body 1 to rotate, so that it can run at normal speed after being connected to the finishing mill leveling machine.

[0034] Example 2: In order to solve the problems of the existing transfer gearbox of the finishing mill leveling machine in actual use, this example discloses the following technical solution: a transfer mechanism is provided on the front of the transfer gearbox body 1, and the transfer mechanism includes a transmission output shaft 6, and a transmission gear 7 is fixedly installed on the middle outer wall of the transmission output shaft 6; the rear end of the transmission output shaft 6 included in the transfer mechanism is installed through a bearing on the left side of the front of the transfer gearbox body 1, and the rear end of the transmission output shaft 6 is fixedly connected to the front end of the driven rotating shaft 9, and the transmission output shaft 6 drives the transmission gear 7 on the middle outer wall to rotate.

[0035] The transfer mechanism includes a transfer output shaft 10, and the rear end of the transfer output shaft 10 is rotatably mounted on the right side of the front of the transfer housing body 1 via a bearing. The upper and lower sides of the transfer output shaft 10 are provided with positioning grooves 11. The transfer mechanism includes a positioning bushing 12, and the positioning bushing 12 is slidably sleeved on the outer wall of the transfer output shaft 10. The upper and lower sides of the positioning bushing 12 are fixedly mounted with positioning sliders 13, and the positioning sliders 13 are slidably mounted in the positioning grooves 11 inside the transfer output shaft 10.

[0036] The transfer mechanism includes a toggle connection groove 14, which is opened on the front and rear sides of the outer side of the positioning bushing 12. The interior of the symmetrically opened toggle connection groove 14 is engaged with the left end of the transfer fork 15. The transfer fork 15 drives the positioning bushing 12 to slide back and forth on the outer wall of the transfer output shaft 10. The transfer mechanism includes a transfer gear 16, which is fixedly installed on the middle outer wall of the positioning bushing 12. In the initial state, the positioning bushing 12 and the transfer gear 16 are located at the front end of the transfer output shaft 10. When the transfer gear 16 moves backward with the positioning bushing 12, it meshes with the transmission gear 7 on the left side. The diameter of the transfer gear 16 is larger than the diameter of the transmission gear 7.

[0037] like Figures 2-3 , Figures 5-6As shown, when the transfer case body 1 needs to reduce speed, the transfer fork 15 on the right side of the front of the transfer case body 1 is connected, and the transfer fork 15 is inserted into the shifting connection grooves 14 on the front and rear sides of the positioning bushing 12. Then, the positioning bushing 12 and the transfer gear 16 outside the transfer fork 15 move backward synchronously. The transfer gear 16 meshes with the transmission gear 7 on the left side. The positioning bushing 12, which is fixedly connected to the transfer gear 16, is slidably installed in the positioning groove 11 inside the transfer output shaft 10 through the positioning sliders 13 on the upper and lower sides inside. So that the rotating positioning bushing 12 drives the internal transfer output shaft 10 to rotate synchronously. At the same time, the diameter of the transfer gear 16 is larger than the diameter of the transmission gear 7, so that the speed of the transfer output shaft 10 is lower than the speed of the transmission output shaft 6. This allows the transfer output shaft 10 to reduce speed after being connected to the finishing mill leveling machine, adapting to different production needs.
