Description

Technical Field

[0001] The utility model relates to the technical field of copper strip production, in particular to a copper strip finishing mill. Background Art

[0002] The existing copper strip finishing structure is relatively common, such as the high-quality finishing copper strip finishing mill with patent number 201821580603.3. For details, please refer to Figure 1 ,like Figure 1 As shown, the finishing mill includes a main rotating device 1, an extrusion mechanism 2 and a conveying device 3. During the finishing rolling process of the copper strip, it needs to pass through multiple rolling mills for rolling. A loop is set between the two rolling mills to hold up the copper strip, as shown in FIG. Figure 2 As shown in the figure, there are three positions of loops, namely positions a, b and c. When the copper strip passes through the looper at position a, the force on the copper strip between the two rolling mills is relatively balanced. When passing through the looper at position b, the folding angle becomes smaller, which makes it easy for the steel to be pulled. When passing through the looper at position c, the folding angle is too large, which makes it easy for stacking to occur. Therefore, before and after use, it is necessary to adjust the specific position range of the looper a. This calculation process and the movement of the looper are relatively cumbersome, resulting in cumbersome finishing steps and low efficiency.

[0003] Therefore, it is necessary to provide a copper strip finishing mill with a fixed copper strip inclination. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] See also Figure 3 and combined Figure 4 , Figure 3 This is a three-dimensional diagram of a preferred embodiment of a copper strip finishing mill according to the present invention; Figure 4 This is a three-dimensional diagram of the best embodiment of the bracket and the fixing frame of the utility model. Figures 3 and 4 As shown, at least one embodiment provides a copper strip finishing mill, comprising: a base 100 and a rolling mechanism 200, the rolling mechanism 200 is rotatably connected to the base 100, the general outline of the base 100 is U-shaped, and the rolling mechanism 200 is the same as in the related art and is not described in detail here; brackets 300 are fixed on both ends of the base 100 on both sides of the rolling mechanism 200, four brackets 300 are fixed on one base 100, and brackets 300 are fixed on both ends of both sides, the two brackets 300 on the same side form a group, and a fixed frame 400 is provided on one side of each bracket 300, and a guide roller 500 is provided between the brackets 300 in the same group, specifically, no less than three guide rollers 500 are provided between the two fixed frames 400 on one side of the base 100, and the copper strip passes through and out of the guide rollers 500 in sequence, and the inclination angle between the copper strip and the rolling mill is determined by the height of the guide roller 500 at the insertion position. According to the thickness and length of the copper strip, the copper strip needs to be aligned with several guide rollers 500 in sequence before being led out.

[0028] Please continue reading Figure 4 and combined Figure 5 , Figure 5 For this utility model Figure 4 The structure diagram at A is enlarged. Figures 4 and 5 As shown, to facilitate adjustment of the height of the initial contact guide roller 500, a fixing hole 301 and an adjustment hole 302 are provided on the bracket 300. The fixing bracket 400 includes a U-shaped clamp 401, which has mounting holes corresponding to the fixing holes 301. The mounting holes and fixing holes 301 are fixedly connected by bolts. The U-shaped clamp 401 also has an arcuate hole 402, which corresponds to the adjustment hole 302. The arcuate hole 402 and the adjustment hole 302 are connected by a latch. After removing the latch, the position of the guide roller 500 can be adjusted by rotating the U-shaped clamp 401.

[0029] Please continue reading Figure 5 .like Figure 5 As shown, the fixing frame 400 also includes a cross piece, which is fixed to one side of the U-shaped clamp 401. The guide rollers 500 are fixed to two opposing cross pieces. The guide rollers 500 are arranged circumferentially with the center point of the cross piece as the center of the circle. In other words, all the guide rollers 500 can form a circular outline.

[0030] Please continue reading Figure 5 and combined Figure 6 , Figure 6 This is a three-dimensional diagram of the optimal embodiment of the guide roller and scraper strip of the utility model. Figures 5 and 6 As shown, the copper strip comes into contact with the external environment before and after rolling, making it susceptible to the adhesion of dust particles and foreign matter caused by electrostatic attraction. To clean the surface of the copper strip, a scraper 600 is provided on the surface of the guide roller 500. Each set of scrapers 600 includes two curved blades, with the curved convex surfaces of the two blades in a set facing each other. The thickness of the scrapers gradually decreases as they move away from the guide roller 500. The two curved cross-sections of the scrapers 600 ensure effective cleaning of the copper strip in both positive and negative contact with the guide roller 500. It should be noted that the scrapers 600 are made of a high-temperature-resistant elastic material.

[0031] In summary, by arranging guide rollers 500 with fixed angles of the copper strip on both sides of the rolling mechanism 200, the angles of the copper strip before entering the rolling mill and after being discharged from the rolling mill can be fixed, thereby avoiding the copper strip entry and discharge angles being too large or too small, and thus solving the problems of steel drawing and steel piling during the copper strip rolling process without adjusting the loop, thereby greatly improving the copper strip rolling efficiency and saving labor costs; by arranging scrapers, the surface of the copper strip is cleaned before entering the rolling mill, thereby avoiding foreign matter adhering to the surface of the copper strip and rolling out pits or cracks.
