Description

Technical Field

[0001] This utility model relates to the field of copper strip processing technology, specifically a hot rolling device for preparing copper strip with improved thickness uniformity. Background Technology

[0002] Copper sheet and strip is a non-ferrous metal material that is widely used in various sectors of the national economy, including power, electronics, aviation, aerospace, shipbuilding, metallurgy, transportation, textiles, and construction. Copper ingots need to be rolled into copper sheets using a hot rolling mill.

[0003] In existing hot rolling equipment, the steel plate is pressed by adjustable pressure rollers and side limiting rollers on both sides. To a certain extent, this can achieve a relatively stable pressing effect on the plate. However, during the extrusion process, because there is a certain distance between the side limiting rollers and the top pressure roller, the thickness of the part that is difficult to press against the outside of the top pressure roller is different from the thickness of the pressed part. As a result, the steel plate may need to be reworked by hot rolling, which affects the processing efficiency. This needs to be optimized and improved. Utility Model Content

[0004] The purpose of this invention is to provide a hot rolling apparatus for preparing copper strip with improved thickness uniformity, in order to solve the problem mentioned in the background art that it is difficult to uniformly press the steel strip during the hot rolling process, which easily leads to rework and reduced processing efficiency.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] like Figure 1 - Figure 4 As shown, this application provides a hot rolling apparatus for preparing copper strip with improved thickness uniformity, comprising: a fixed frame 1, a top plate 2 fixedly connected to the top of the fixed frame 1, and a guide frame 3 fixedly connected to the front end of the fixed frame 1, the guide frame 3 carrying and guiding the steel strip to be processed; a lifting adjustment assembly including a toothed column 14, the toothed column 14 slidably connected to the inner side of the top plate 2, and a threaded rod 12 connected to the outer side of the toothed column 14, and an adjusting plate 10 connected to the inner side of the threaded rod 12, the lifting adjustment assembly being used for adjusting the height of the top hot rolling press; specifically, as shown... Figure 1 As shown, a conveyor belt 4 is fixedly installed on the inner bottom of the fixed frame 1. The conveyor belt 4 is used to transport the steel strip to be hot rolled. Adjustment grooves 5 that are slidably connected to the slider 6 are opened on both sides of the outer wall of the fixed frame 1. A slide rail is set on the inner side of the adjustment groove 5 to facilitate the guidance and restriction of the lifting and lowering of the slider 6.

[0019] Specifically, such as Figure 2 As shown, a telescopic cylinder 7 is fixedly connected to the inner side of the slider 6, and a rotating clamping block 8 is installed on the inner side of the telescopic cylinder 7. The telescopic cylinder 7 controls the rotating clamping block 8 to move inward to adapt to upper pressure rollers 9 of different lengths. The upper pressure roller 9 is connected to the inner side of the rotating clamping block 8, and a power shaft is connected to the inner side of the rotating clamping block 8 to provide rotational power to the upper pressure roller 9.

[0020] Specifically, such as Figure 3 As shown, a connecting seat 15 is fixedly connected to the inner side of the top plate 2. The connecting seat 15 is rotatably connected to the toothed column 14. A turntable 16 is fixedly connected to the top of the toothed column 14. The turntable 16 is used for manual control of rotation, which facilitates the control of the toothed column 14 to rotate inside the connecting seat 15.

[0021] Specifically, such as Figure 3 As shown, a gear 13 meshes with the outer side of the gear 14, and a threaded rod 12 is fixedly connected to the bottom end of the gear 13. The rotation of the gear 14 will cause the gear 13 to rotate on its outer side, and at the same time, the height position will change.

[0022] Specifically, such as Figure 3 As shown, the bottom end of the threaded rod 12 is rotatably and fixedly connected to the rotating shaft 11, and the adjusting plate 10 is fixedly connected to the outside of the rotating shaft 11. As the gear 13 rotates, the threaded rod 12 can be adjusted by thread lifting and lowering on the inside of the adjusting plate 10, which drives the adjusting plate 10 at the bottom end to lift and lower. The outside of the rotating shaft 11 is fixedly connected to the adjusting plate 10, and the inside of the rotating shaft 11 is fixedly connected to the threaded rod 12, so that when the threaded rod 12 rotates, the adjusting plate 10 only needs to maintain stable lifting and lowering adjustment.

[0023] The side pressure adjustment assembly includes a slider 6, which is slidably connected to the outside of the fixed frame 1. A positioning seat 18 is connected to the inside of the slider 6, and a side pressure roller 20 is rotatably connected to the bottom end of the positioning seat 18. The side pressure adjustment assembly is used for side shaping and extrusion of the steel strip.

[0024] Specifically, such as Figure 4 As shown, an elastic connecting rod 17 is slidably connected to the inner side of the adjusting plate 10, and a positioning seat 18 is fixedly connected to the bottom end of the elastic connecting rod 17. A spring is connected to the outer side of the elastic connecting rod 17, and the bottom end of the spring is fixedly connected to the positioning seat 18, while the top end is fixedly connected to the bottom of the adjusting plate 10.

[0025] Specifically, such as Figure 4 As shown, a motor 19 is installed on the inner top of the positioning seat 18, and the side pressure roller 20 is connected to the bottom output end of the motor 19. The motor 19 is used to provide power to the side pressure roller 20, so that the side pressure roller 20 can squeeze and adjust the side of the steel strip.

[0026] In this embodiment: When hot rolling the steel strip, two sets of adjustable side pressure rollers 20 are set to limit and squeeze the sides of the steel strip. The first set is used for qualitative shaping, and the upper pressure roller 9, which can be raised and lowered, is used for pressing and adjustment. Then, the side pressure rollers 20 are used for trimming, which improves the uniformity of hot rolling during steel strip transmission and reduces the number of rework. When hot rolling steel strips of different sizes, the rotating clamp 8, whose position can be stably adjusted, is used for adaptive adjustment. The side pressure rollers 20, which can be raised and lowered within a certain range, are used for side protection and squeezing, which can improve the applicability of the equipment.

[0027] Specifically, the solution is as follows: When hot rolling copper strip, the raw material is first guided to the top of the conveyor belt 4 through the guide frame 3. Then, according to the processing dimensions of the steel strip blank, the upper pressure roller 9 is replaced accordingly. The position of the rotating clamp 8 is controlled by the telescopic cylinder 7. The rotating clamp 8 slides on the inner side of the adjusting plate 10, which can improve the stability of the adjustment. After the upper pressure roller 9 is installed, the height of the upper pressure roller 9 is adjusted by rotating the turntable 16, which causes the toothed column 14 to drive the gear 13 to rotate and rise, thereby driving the adjusting plate 10 at the bottom to adjust the height. The outer side of the adjusting plate 10... By sliding the connecting slider 6 inside the adjusting groove 5, the stability of the lifting adjustment can be improved. There are four side pressure rollers 20 at both ends of the upper pressure roller 9. The side pressure rollers 20 are connected by the elastic connecting rod 17 and can be adjusted for applicability. They are always located outside the upper pressure roller 9 to limit the compression. When the steel strip is transported, the first set of side pressure rollers 20 presses against the steel strip to limit the compression amplitude. Then, the upper pressure roller 9 presses and adjusts the strip to achieve a relatively uniform thickness. Finally, the second set of side pressure rollers 20 trims the strip, improving the uniformity of hot rolling during steel strip transport and improving the processing quality.

[0028] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
