Description

Technical Field

[0001] This invention belongs to the field of sheet material feeding technology for rolling mills, specifically relating to a copper plate clamping and feeding device and method for copper-aluminum composite plate production. Background Technology

[0002] With the vigorous development of new energy vehicles, the demand for batteries in these vehicles is gradually increasing. As a crucial component of battery packs, the demand for copper-aluminum composite plates is also rising significantly, along with the increasing demands for their quality. Current production processes for copper-aluminum composite materials mainly involve continuous casting and rolling. However, when using existing equipment to produce copper-aluminum composite plates via continuous casting and rolling, inconsistencies easily arise between the feed speed of the copper plates and the feed speed of the aluminum plates, leading to delamination in the produced copper-aluminum composite plates and rendering the material unusable.

[0003] If the existing aluminum plate production machine is used to directly produce copper-aluminum composite plates, the quality of the produced copper-aluminum composite plates will be reduced because the copper plate cannot fit tightly with the rolling mill rolls when it is fed into the rolling mill rolls. This will cause the surface speed of the rolling mill rolls and the feed speed of the copper plate to be inconsistent, resulting in a decrease in the quality of the produced composite plates. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a copper plate clamping and feeding device and method for the production of copper-aluminum composite panels, which effectively improves the yield of the produced copper-aluminum composite panels.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A copper plate clamping and feeding device for copper-aluminum composite plate production includes a double-roll mill, linear guide rails, and a clamping slide mechanism. The double-roll mill frame has linear guide rails installed symmetrically on both inner sides, with the linear guide rails at the same horizontal height as the roll axes of the double-roll mill. Horizontal tracks are machined on the linear guide rails, and linear cylinders are installed on them. The sliding component of the clamping slide mechanism is horizontally slidable within the tracks. The actuating end of the linear cylinder is connected to the clamping slide mechanism. A clamping roller is installed on the clamping slide mechanism, arranged parallel to the rolls of the double-roll mill. The clamping roller is connected to a drive assembly for rotating the clamping roller so that its rotational speed matches the linear velocity of the roll surface.

[0007] Furthermore, the drive assembly includes a drive motor, a motor shaft pulley, and a pressure roller pulley. The drive motor is fixed on the pressure slide mechanism. The output shaft of the drive motor is arranged parallel to the pressure roller. The motor shaft pulley is mounted on the output shaft of the drive motor and meshes with the pressure roller pulley. The pressure roller pulley is coaxially mounted with the pressure roller. Both the output shaft and the pressure roller are rotatably mounted on the pressure slide mechanism. Of course, other drive methods, such as hydraulic systems, can also be used.

[0008] Preferably, the pressing slide mechanism is equipped with a pressing roller and a motor base. The motor base is fixedly connected to the pressing slide mechanism, and the pressing slide mechanism is horizontally slidably connected to a linear slide rail. The actuating end of the linear cylinder is fixedly connected to the pressing slide mechanism. The pressing slide mechanism is machined with a pressing roller bearing seat and a motor shaft bearing seat. The pressing roller pulley is connected to the pressing roller via a shoulder and a key. The motor shaft pulley is connected to the output shaft via a key. The output shaft is connected to the drive motor via a coupling. The drive motor is fixedly connected to the motor base, and the pressing roller is driven by meshing with the motor shaft pulley.

[0009] Furthermore, a drive motor is vertically mounted on the pressing slide mechanism. The output end of the drive motor is connected to the output shaft via a coupling to provide power. The output shaft is positioned and mounted with a motor shaft bearing via a shoulder. The motor shaft bearing is positioned and mounted in the drive motor shaft bearing seat of the pressing slide mechanism via a shoulder and a hole. The pressing roller pulley is positioned and fixed to the pressing roller by a key via a shoulder. The pressing roller is positioned and mounted with a pressing roller bearing via a shoulder. The pressing roller bearing is positioned and mounted in the pressing roller bearing seat of the pressing slide mechanism via a shoulder and a hole.

[0010] Furthermore, the linear slide rail is provided with through holes, through which fasteners fix the linear slide rail to the frame of the double-roll mill.

[0011] A method for clamping and feeding copper plates in the production of copper-aluminum composite panels includes the following steps:

[0012] Step 1: Keep the rotational speed of the drive motor constant to ensure that the surface linear velocity of the pressure roller is still consistent with that of the roller when it disengages from the roll. Contract the linear cylinders on both sides to drive the pressure slide mechanism to move in the direction of the linear cylinders, so that the pressure roller disengages from the roll. Turn off the drive motors on both sides to stop the pressure roller from rotating.

[0013] Step 2: The copper plate is wound around the roller, and the drive motor is started to make the clamping roller start to rotate. The speed of the drive motor is adjusted so that the linear velocity of the clamping roller surface is consistent with the linear velocity of the roller surface. At the same time, the linear cylinders on both sides are extended, driving the clamping slide mechanism to move towards the roller, so that the clamping roller presses against the roller. At this time, while the clamping roller presses against the copper plate, it ensures that the movement speed of the two surfaces of the copper plate is consistent.

[0014] If existing aluminum plate production machines are used to directly produce copper-aluminum composite panels, the quality of the produced panels will be reduced because the copper plate cannot adhere tightly to the rolling mill rolls during rolling. This inconsistency between the surface speed of the rolling mill rolls and the feed speed of the copper plate leads to a decrease in the quality of the composite panels produced. This invention is installed on columns on both sides of the original machine's rolling mill rolls. A drive motor rotates the press roller to match the linear speed of the rolling mill rolls. Initially, a cylinder can be controlled to allow the press roller to press against or disengage from the rolling mill rolls, ensuring that the copper plate is in close contact with the rolling mill rolls at all times. This improves the yield rate of the produced copper-aluminum composite panels.

[0015] The main benefits of this invention are: it effectively improves the yield rate of the produced copper-aluminum composite panels. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] Reference Figures 1-3A copper plate clamping and feeding device for copper-aluminum composite plate production includes a double-roll mill 1, a linear slide rail 2, and a clamping slide mechanism 3. The double-roll mill 1 has linear slide rails 2 installed symmetrically on both inner sides of its frame. The linear slide rails 2 are at the same horizontal height as the roll axes of the double-roll mill 1. A horizontal slide rail is machined on the linear slide rail 2. A linear cylinder 22 is installed on the linear slide rail 2. The sliding component of the clamping slide mechanism 3 is horizontally slidable within the slide rail. The actuating end of the linear cylinder 22 is connected to the clamping slide mechanism 3. A clamping roller 31 is installed on the clamping slide mechanism 3. The clamping roller 31 is arranged parallel to the rolls of the double-roll mill 1. The clamping roller 31 is connected to a drive assembly for rotating the clamping roller so that its rotational speed matches the linear velocity of the roll surface.

[0022] Furthermore, the drive assembly includes a drive motor 323, a motor shaft pulley 321, and a pressure roller pulley 311. The drive motor 323 is fixed on the pressure slide mechanism 3. The output shaft 322 of the drive motor 323 is arranged parallel to the pressure roller 31. The motor shaft pulley 321 is mounted on the output shaft 322 of the drive motor 323, and the motor shaft pulley 321 meshes with the pressure roller pulley 311. The pressure roller pulley 311 is coaxially mounted with the pressure roller 31. Both the output shaft 322 and the pressure roller 31 are rotatably mounted on the pressure slide mechanism 3. Of course, other drive methods, such as hydraulic systems, can also be used.

[0023] The pressing slide mechanism 3 is equipped with a pressing roller 31 and a motor base 32. The motor base 32 is connected to the pressing slide mechanism 3 by screws. The pressing slide mechanism 3 is horizontally slidably connected to the linear slide rail 2. The actuating end of the linear cylinder 22 is fixedly connected to the pressing slide mechanism. The pressing slide mechanism 3 is machined with a pressing roller bearing seat 33 and a motor shaft bearing seat 34. The pressing roller pulley 311 is connected to the pressing roller 31 by a shoulder and a key. The motor shaft pulley 321 is connected to the output shaft 322 by a key. The output shaft 322 is connected to the drive motor 323 by a coupling 324. The drive motor 323 is connected to the motor base 32 by screws. The pressing roller 31 is driven by the meshing of the pressing roller pulley 311 and the motor shaft pulley 321. The pressing slide mechanism 3 can only move horizontally along the linear slide rail 2.

[0024] Specifically, the linear guide 2 serves as a guide and load-bearing element for the clamping slide mechanism 3, enabling the clamping slide mechanism 3 to move horizontally in a straight line along the axis of the roll. The linear cylinder 22 drives the clamping slide mechanism 3 to move linearly, pressing or releasing the copper plate from the roll.

[0025] A drive motor 323 is vertically mounted on the pressing slide mechanism 3. The output end of the drive motor 323 is connected to the output shaft 322 via a coupling 324 to provide power. A motor shaft bearing 35 is mounted on the output shaft 322 via a shoulder. The motor shaft bearing 35 is mounted in the drive motor shaft bearing seat 34 of the pressing slide mechanism 3 via a shoulder and a hole. The pressing roller pulley 311 is fixed to the pressing roller 31 via a shoulder and a key. A pressing roller bearing 36 is mounted on the pressing roller 31 via a shoulder. The pressing roller bearing 36 is mounted in the pressing roller bearing seat 33 of the pressing slide mechanism 3 via a shoulder and a hole.

[0026] The linear slide rail 2 is provided with a through hole 21, and the fasteners fix the linear slide rail 21 to the frame 1 of the double roll mill through the through hole 21.

[0027] In this embodiment, by simultaneously driving the two drive motors 323 to drive the motor shaft pulley 321 to mesh with the pressure roller pulley 311 on the pressure roller 31, the circumferential motion linear speed of the pressure roller 31 is consistent with the rolling mill linear speed.

[0028] A method for clamping and feeding copper plates in the production of copper-aluminum composite panels includes the following steps:

[0029] Step 1: Keep the rotational speed of the drive motor constant to ensure that the surface linear velocity of the pressure roller is still consistent with that of the roller when it disengages from the roll. Contract the linear cylinders on both sides to drive the pressure slide mechanism to move in the direction of the linear cylinders, so that the pressure roller disengages from the roll. Turn off the drive motors on both sides to stop the pressure roller from rotating.

[0030] Step 2: The copper plate is wound around the roller, and the drive motor is started to make the clamping roller start to rotate. The speed of the drive motor is adjusted so that the linear velocity of the clamping roller surface is consistent with the linear velocity of the roller surface. At the same time, the linear cylinders on both sides are extended, driving the clamping slide mechanism to move towards the roller, so that the clamping roller presses against the roller. At this time, while the clamping roller presses against the copper plate, it ensures that the movement speed of the two surfaces of the copper plate is consistent.

[0031] If existing aluminum plate production machines are used to directly produce copper-aluminum composite panels, the quality of the produced panels will be reduced because the copper plate cannot adhere tightly to the rolling mill rolls during rolling. This inconsistency between the surface speed of the rolling mill rolls and the feed speed of the copper plate leads to a decrease in the quality of the composite panels produced. The device in this embodiment is installed on columns on both sides of the original machine's rolling mill rolls. A drive motor rotates the device to ensure that the linear speed of the pressure roller and the rolling mill rolls are consistent. Initially, a cylinder can be controlled to allow the pressure roller to press against or move away from the rolling mill rolls, ensuring that the copper plate is in close contact with the rolling mill rolls at all times. This improves the yield rate of the produced copper-aluminum composite panels.

The scope of protection of this invention should not be considered limited to the specific forms described in these embodiments; rather, it extends to equivalent technical means conceived by those skilled in the art based on the inventive concept.
