Description

Technical Field

[0001] This utility model belongs to the field of copper-based steel strip processing technology, and in particular relates to a copper-based steel strip lead-free segregation suppression guide rolling mill. Background Technology

[0002] Roll forming is a common processing method in the processing of copper-based steel strip, used to adjust performance indicators such as strip thickness and flatness. Lead segregation is prone to occur during continuous rolling of copper-based steel strip, affecting material uniformity and mechanical properties.

[0003] Traditional guide rolling mills mostly use fixed roll pressing structures, which are difficult to dynamically adapt to the processing requirements of strips of different thicknesses. Existing equipment lacks an effective positioning mechanism during the steel strip introduction stage, which makes copper-based steel strips prone to lateral displacement when entering the roll gap, exacerbating segregation defects.

[0004] Conventional guiding mechanisms are not effective enough in vertical positioning and edge protection of steel strips. Especially during high-speed rolling of thin copper-based steel strips, they can easily cause surface scratches or edge warping, further reducing the yield of finished products.

In this invention, the device uses a spring-loaded guide structure to adapt to changes in steel strip width, and a liftable third sleeve to achieve lateral positioning and vertical limiting, ensuring stable guidance of the steel strip and preventing edge warping. A cylinder-driven rotating plate adjusts the height of the guide rollers, ensuring precise strip entry and maintaining stable tension.

The two connecting brackets 24 are located near both ends of the driven roller 8, and a fixing post 34 is fixedly installed at one end of each connecting bracket 24. One end of each fixing post 34 passes through an adjacent clearance groove 33 and slides with the inner wall of the corresponding clearance groove 33 to achieve synchronous lifting and lowering of the third sleeve 31 along with the multiple driven rollers 8. The two third sleeves 31 cooperate with the top of the guide plate 9 to provide vertical limiting guidance for the copper-based steel strip in the positioning guide.

[0030] In this embodiment, the pressing assembly cooperates with the guide plate 9 to achieve initial positioning of the copper-based steel strip and subsequent tension adjustment.

By controlling the extension and retraction of the piston rods of the second cylinders 18, the two rotating plates 11 are driven to rotate, thereby bringing the guide roller 12 closer to the guide plate 9, completing the pressing and guiding of the copper-based steel strip, and allowing for tension adjustment of the copper-based steel strip in subsequent processing.

[0031] This application can be used in the field of copper-based steel strip processing technology, as well as in other fields applicable to this application.

[0032] In another embodiment: Reference Figure 1 , 7 A copper-based steel strip lead-free segregation suppression guide rolling mill is applied to the field of copper-based steel strip processing technology. In this embodiment, grooves are provided on the sides of the two supporting side plates 2 that are close to each other. The grooves are located above the corresponding clearance holes 25 and are used to allow the corresponding connecting plates 32 to make way.

[0033] In this embodiment, the outer walls of the two abutting blocks located in the corresponding clearance holes 25 are threaded, and one end of each abutting block is provided with a hexagonal groove. The two abutting blocks are threadedly connected to the inner wall of the corresponding clearance holes 25 so as to complete the disassembly, assembly and maintenance of the adjacent springs 30.

[0034] However, as is well known to those skilled in the art, the working principles and wiring methods of the first cylinder 10, the first motor 13, the second cylinder 18, and the second motor 22 are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0035] The usage process and working principle of this utility model technical solution are as follows: In use, the copper-based steel strip enters the equipment from the side where the guide assembly is installed. The steel strip first enters the area of ​​the guide plate 9, at which point the guide roller 12 of the pressing assembly is in a raised state.

[0036] Next, the two guide rods 27 laterally position the steel strip. The second sleeve 28 abuts against the spring 30 inside the relief hole 25 via the connecting rod 29. The spring 30 provides a buffering force to make the guide rods 27 adapt to the width of the steel strip. After one end of the steel strip is positioned by the guide rods 27, it will continue to stay in the area of ​​the guide plate 9, and then the guide roller 12 can be controlled to descend.

[0037] When control of the guide roller 12 is required, the second cylinder 18 is activated to push the first sleeve 16, which in turn drives the rotating plate 11 to rotate downward around the rotating shaft 14. This causes the guide roller 12 to press against the steel strip on the guide plate 9, deforming the steel strip and ensuring that its end is close to the guide plate 9, facilitating its subsequent entry between the drive roller 7 and the driven roller 8. Then, the first motor 13 drives the guide roller 12 to rotate, assisting in the forward transport of the steel strip. The steel strip then enters the rolling area between the drive roller 7 and the driven roller 8. At this time, multiple drive rollers 7 rotate synchronously via the chain of the drive assembly, driving the steel strip to move. The driven roller 8 is linked to the lifting frame 6 via the lifting seat 5. The first cylinder 10 pushes the lifting frame 6 to adjust the downward pressure of the driven roller 8, allowing the steel strip to pass through the rolling gap under a preset pressure to complete the processing.

[0038] During the processing, the third sleeve 31 above the roller pressing assembly rises and falls synchronously with the driven roller 8. The connecting plate 32 connected to it slides with the fixed column 34 through the relief groove 33, which can ensure that it will not affect the positioning effect of the guide rod 27 on the steel strip. As the third sleeve 31 descends, the third sleeve 31 can abut against the edge of the top of the steel strip to achieve vertical positioning of the steel strip, which facilitates ensuring that the steel strip enters the space between the driving roller 7 and the driven roller 8 to complete the processing.

[0039] During the steel strip conveying process, the angle of the rotating plate 11 is changed by the second cylinder 18, and the height of the guide roller 12 is changed to extrude the steel strip, thus maintaining a stable processing tension. The steel strip is finally output from one side of multiple drive rollers 7, completing the corresponding roll forming process.
