Detailed implementation manners

[0023] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0024] Please refer to Figure 2 , Figure 2 , which is a three-dimensional view of the optimal embodiment of the annealing device for tin phosphor bronze strip of the present utility model. As Figure 2 shown, at least one embodiment provides an annealing device for tin phosphor bronze strip, including: a preheating box 100, a high-temperature box 200 and a cooling box 300. The preheating box 100, the high-temperature box 200 and the cooling box 300 are interconnected to form an annealing chamber. It should be additionally noted that a water vapor spraying system is provided in the cooling box 300 for cooling the tin phosphor bronze strip. In addition, a pay-off device for the tin phosphor bronze strip is provided on one side of the preheating box 100, a reeling device is provided on one side of the cooling box 300, and a conveying support net 600 is provided at the middle position of the preheating box 100, the high-temperature box 200 and the cooling box 300. The pay-off device and the reeling device horizontally support the tin phosphor bronze strip through the conveying support net 600, so that the tin phosphor bronze strip slowly moves in the annealing chamber under the action of the reeling device and the pay-off device. A copper strip inlet 400 is provided on one side of the preheating box 100, and a copper strip outlet 500 is provided on one side of the cooling box 300. After the tin phosphor bronze strip coil is cut and reeled, it directly moves from the reeling operation station to the annealing station. Metal chips generated by cutting are likely to remain on the surface of the tin phosphor bronze strip coil. If the metal chips and the tin phosphor bronze strip enter the high-temperature box 200 together, the metal chips will melt on the surface of the tin phosphor bronze strip, making the surface of the tin phosphor bronze strip have convex points. Therefore, a cleaning structure 700 is provided at the edges of the copper strip outlet 500 and the copper strip inlet 400.

[0025] Please refer to Figure 3 and in combination with Figure 4 , Figure 3 , which is a three-dimensional view of the optimal embodiment of the cleaning structure of the present utility model; Figure 4 , which is a sectional view of the optimal embodiment of the cleaning structure of the present utility model. As Figures 3 to 4As shown in the figure, the cleaning structure 700 includes a guiding frame 701. The guiding frame 701 is provided on one side of the preheating box 100 and one side of the cooling box 300. The length of the guiding frame 701 is greater than the width of the tin phosphor bronze strip. An extrusion part 703 is provided on one side of the guiding frame 701. The inclined surface 702 has a high side and a low side. The extrusion part 703 is provided on the high side of the inclined surface 702. The extrusion part 703 includes two elastic strips 7031. The elastic strips 7031 are made of high-temperature resistant and water-absorbing materials, which can dry the water vapor and clean the metal chips. A plurality of micropits are provided on the surface of the elastic strips 7031. The outer contour of the elastic strips 7031 is formed by a right-angled side and an arc-shaped side. The arc-shaped side is an arc-shaped protrusion 7032. A shuttle gap 7033 is formed between the two arc-shaped sides. In the natural state, the height of the shuttle gap 7033 is less than the thickness of the tin phosphor bronze strip. When the tin phosphor bronze strip passes through the guiding frame 701, the top surface and the bottom surface of the tin phosphor bronze strip are both in contact with the arc-shaped protrusion 7032. At this time, the micropits increase the contact friction between the two, enhancing the effect of removing metal chips. A chamfer is provided on the bottom surface of the guiding frame 701. The chamfer forms an inclined surface 702 on the bottom surface of the guiding frame 701. The inclined surface 702 slopes downward from the inner direction of the annealing chamber to the outer direction of the annealing chamber. A plurality of leakage holes 704 are provided on the inclined surface 702. The leakage holes 704 are used to drain the metal chips or water droplets below the guiding frame 701.

[0026] In summary, by arranging the cleaning structure 700 at the positions of the copper strip outlet 500 and the copper strip inlet 400, not only can the metal attachments on the surface of the tin phosphor bronze strip be prevented from integrating with the tin phosphor bronze strip to form bumps during the annealing process, but also the tin phosphor bronze strip cooled by water vapor can be cleaned, improving the annealing efficiency; by arranging the elastic strips 7031 and the inclined surface 702, the retention of metal chips and water vapor is avoided, enhancing the cleaning effect and improving the surface cleanliness of the tin phosphor bronze strip.
