Description

Technical Field

[0001] This utility model relates to the technical field of metal rolling, specifically to a rolling equipment for oxygen-free copper strip. Background Technology

[0002] Traditional oxygen-free copper strip rolling processes commonly suffer from uneven rolling force distribution, strip misalignment, and uneven winding. Existing equipment often uses a single roll group for one-time rolling, which can easily lead to stress concentration within the copper strip, affecting material properties. Furthermore, conventional traction and winding mechanisms lack tension adjustment capabilities, easily causing surface scratches or loose winding during high-speed rolling. In addition, the connection between the copper strip and the traction device is often complex, impacting production efficiency. Therefore, there is an urgent need to develop an oxygen-free copper strip rolling machine capable of progressive rolling, automatic tension adjustment, and easy, rapid clamping to improve product quality and production efficiency.

[0003] A search revealed Chinese Patent Publication No. CN213256280U, which discloses an adjustable metal rolling mill. The mill includes a main body comprising a base and two rolling rollers positioned above it. Each rolling roller has a fixing block on both sides. The bottoms of the two lower fixing blocks are fixedly connected to the top of the base. Two rotating shafts are located above the base, with the rolling rollers fixedly mounted on their respective shafts. The fixing blocks are rotatably mounted on their corresponding shafts. A first drive motor is fixedly installed on the right side of the right fixing block among the two lower fixing blocks. This invention is reasonably designed, allowing for adjustment of the distance between the two rolling rollers according to actual needs, thereby adjusting the thickness of the rolled metal. This improves its applicability and enables stable metal rolling operations after adjustment, meeting usage requirements and facilitating practical application.

[0004] However, the shortcomings of this device are: it only controls the thickness by adjusting the gap between the rolling rolls, lacks dynamic control of the rolling force and roll speed, which can easily lead to uneven stress in the metal strip; and it does not have a guiding and tension stabilizing mechanism, which may cause deviation or surface damage during high-speed rolling. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a rolling equipment for oxygen-free copper strip, which solves the problems of existing devices lacking multi-stage precision rolling capabilities and a stable and reliable traction winding system.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rolling device for oxygen-free copper strip, comprising a box, a guide belt, and a collecting cylinder. The collecting cylinder is located inside the box, and the collecting cylinder is equipped with the guide belt. A sleeve is fixedly connected inside the collecting cylinder, and a telescopic rod is located inside the sleeve. A moving block is fixedly connected to the upper end of the telescopic rod, and the lower outer wall of the moving block is fixedly connected to the upper end of a spring. The lower end of the spring is fixedly connected to the upper end of the sleeve. Two holes are provided at the connection end between the guide belt and the sleeve, and protective rings are provided in the holes to prevent the guide belt from directly contacting and tearing the sleeve under the traction of the sleeve.

[0007] In use, the device involves pulling down the moving block to insert the guide belt into the sleeve, driving the second rotating motor to pre-wrap the guide belt several times on the collecting cylinder to improve its stability and prevent the sleeve from cracking when the copper strip is pulled. Workers use steel wire to pass through and fix the through hole or through groove on one side of the guide belt, pull the steel wire to pull the guide belt from between the rolling cylinders to the copper strip, remove the steel wire, pass the copper strip through the two through grooves, and use tools to drive screws into the through hole to fix the copper strip on the guide belt. The first rotating motor, the third rotating motor, and the second rotating motor are started in sequence. The copper strip is gradually rolled through three pairs of rolling cylinders with progressively decreasing spacing. The second rotating motor drives the guide belt to move, and the guide belt provides tension to the copper strip to assist in the lateral movement of the copper strip during rolling. It also rotates with the copper strip on the collecting cylinder to complete the coiling and recycling of the copper strip.

[0008] Preferably, a second rotating motor is fixedly connected to one side of the outer wall of the box, the output shaft of the second rotating motor is fixedly connected to the rotation center of the collecting cylinder, the guide belt is connected to the collecting cylinder through a sleeve, and the collecting cylinder is provided with a slot to provide space for the installation of the guide belt.

[0009] Preferably, one end of the guide strip has two through slots and two through holes, the through holes being pre-drilled holes for screw installation. The surface of the partition between the through slots has anti-slip textures to further stabilize the tension of the guide strip on the copper strip.

[0010] Preferably, a first rotating motor is fixedly connected to the outer wall of one side of the housing. The output shaft of the first rotating motor is fixedly connected to the rotation center of the first rotating ring. The first rotating ring is connected to the first rolling cylinder. The first rotating ring is connected to the second rotating ring above it via a belt. The first rolling cylinder, the second rolling cylinder, and the third rolling cylinder are all designed in pairs, symmetrically arranged, and the spacing between each pair of rolling cylinders decreases sequentially.

[0011] Preferably, a third rotating motor is fixedly connected to one side of the outer wall of the housing. The output shaft of the third rotating motor is fixedly connected to the rotation center of the third rotating ring. The third rotating ring is connected to the third rolling cylinder. The third rotating ring is connected to the second rotating ring below via a belt. The second rotating ring is connected to the second rolling cylinder.

[0012] Preferably, the lower end of the housing is provided with a support, and the lower end of the support is provided with a base, the base being a frustum-shaped design.

[0013] This invention provides a rolling equipment for oxygen-free copper strip. It has the following beneficial effects:

[0014] 1. This oxygen-free copper strip rolling equipment utilizes three rolling units—a first rolling drum, a second rolling drum, and a third rolling drum—with their spacing decreasing sequentially along the copper strip's travel direction, forming a progressive rolling structure. As the copper strip passes through different rolling drums, its thickness is gradually compressed, avoiding stress concentration or surface cracks caused by large single deformations. Simultaneously, the first and third rotating motors synchronously drive adjacent rolling drums via belts, ensuring matching rolling speeds and reducing the risk of stretching or accumulation of the copper strip during rolling. This stepped thinning design not only improves rolling accuracy but also makes the internal grain structure of the copper strip more uniform, ultimately resulting in oxygen-free copper strip with high surface quality.

[0015] 2. This oxygen-free copper strip rolling equipment, in operation, forms a highly efficient copper strip traction-winding system through the cooperation of a guide belt and a collecting cylinder. The guide belt is fixed to the end of the copper strip via through slots and holes, and pre-wound several turns under the drive of a second rotating motor to ensure a stable connection. During rolling, the guide belt continuously provides tension, assisting the copper strip to pass smoothly through the rolling cylinder and preventing slippage or deviation. Simultaneously, a buffer mechanism consisting of springs and telescopic rods can dynamically adjust the tension to adapt to different rolling speeds. The collecting cylinder ultimately automatically winds the rolled copper strip into a coil, achieving continuous production and significantly improving material collection efficiency and coil uniformity.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-4 This utility model provides a rolling equipment for oxygen-free copper strip, including a housing 1, a guide belt 17, and a collecting cylinder 21. The collecting cylinder 21 is provided inside the housing 1, and the collecting cylinder 21 is provided with the guide belt 17. A sleeve 10 is fixedly connected inside the collecting cylinder 21, and a telescopic rod 9 is provided inside the sleeve 10. A moving block 7 is fixedly connected to the upper end of the telescopic rod 9. The lower outer wall of the moving block 7 is fixedly connected to the upper end of a spring 8, and the lower end of the spring 8 is fixedly connected to the upper end of the sleeve 10. In use, pulling down the moving block 7 can cause the spring 8 and the telescopic rod 9 to retract. After the guide belt 17 is installed, the moving block 7 is released, the spring 8 releases the elastic tension, and the moving block 7 returns to its original position, thus completing the rapid installation of the guide belt 17.

[0025] Example 2

[0026] Please see Figure 1-4 In this embodiment, a second rotating motor 12 is fixedly connected to the outer wall of one side of the box 1. The output shaft of the second rotating motor 12 is fixedly connected to the rotation center of the collecting cylinder 21. The guide belt 17 is connected to the collecting cylinder 21 through the sleeve 10. When in use, the second rotating motor 12 is driven to make the collecting cylinder 21 rotate and pre-wind the guide belt 17 a certain number of turns, thereby enhancing the fixing effect of the guide belt 17 and providing stronger stability for pulling the copper strip later.

[0027] The guide belt 17 has two through slots 19 at one end and two through holes 20 at the other end. The guide belt 17 transmits torque through the pre-winding fixing part. The copper strip traction part synchronously winds up the rolled copper strip. The tension buffer part balances the pulling force caused by the speed difference of the rolling drum. The motion guide part ensures that the contact pressure between the copper strip and the rolling drum is evenly distributed.

[0028] A first rotating motor 13 is fixedly connected to the outer wall of one side of the housing 1. The output shaft of the first rotating motor 13 is fixedly connected to the rotation center of the first rotating ring 18. The first rotating ring 18 is connected to the first rolling cylinder 6. The first rotating ring 18 is connected to the upper second rotating ring 16 through a belt 15. In use, the first rotating motor 13 is driven to make the first rotating ring 18 rotate. Since the first rotating ring 18 and the upper second rotating ring 16 are connected through the belt 15, the first rotating ring 18 and the upper second rotating ring 16 can rotate simultaneously.

[0029] A third rotating motor 11 is fixedly connected to the outer wall of one side of the housing 1. The output shaft of the third rotating motor 11 is fixedly connected to the rotation center of the third rotating ring 14. The third rotating ring 14 is connected to the third rolling cylinder 4. The third rotating ring 14 is connected to the lower second rotating ring 16 through a belt 15. The second rotating ring 16 is connected to the second rolling cylinder 5. In use, the third rotating motor 11 is driven to make the third rotating ring 14 rotate. Since the third rotating ring 14 and the lower second rotating ring 16 are connected through a belt 15, the third rotating ring 14 and the lower second rotating ring 16 can rotate simultaneously.

[0030] The lower end of the housing 1 is equipped with a support 3, and the lower end of the support 3 is equipped with a base 2. The frustum design of the base 2 increases the contact area with the ground, enhancing the stability of the equipment during operation.

[0031] Instructions for use: When using this device, pull down the moving block 7 to put the guide belt 17 into the sleeve 10. Drive the second rotating motor 12 to pre-wrap the guide belt 17 several times on the collecting cylinder 21 to improve the stability of the guide belt 17 and prevent the sleeve 10 from breaking when pulling the copper strip. The worker uses a steel wire to pass through and fix the through hole 20 or through groove 19 on one side of the guide belt 17. Pull the steel wire to pull the guide belt 17 from between the rolling cylinders to the copper strip. Remove the steel wire, pass the copper strip through the two through grooves 19, and use a tool to nail the screw into the through hole 20 to fix the copper strip on the guide belt 17. Start the first rotating motor 13, the third rotating motor 11 and the second rotating motor 12 in sequence. The copper strip is gradually rolled through three pairs of rolling cylinders with decreasing spacing. The second rotating motor 12 drives the guide belt 17 to move. The guide belt 17 provides tension to the copper strip to assist the lateral movement of the copper strip during rolling and rotates on the collecting cylinder 21 with the copper strip to complete the coiling and recycling of the copper strip.
