Description

Technical Field

[0001] The utility model belongs to the technical field of bus bar casting and welding, and particularly relates to a bus bar casting and welding spray cooling device. Background Technique

[0002] In the manufacturing process of lead-acid batteries, casting and welding is a crucial process in the manufacturing of lead-acid batteries. In the existing casting and welding methods of lead-acid batteries, the general process is as follows: immerse the bus bar mold in the lead liquid in the lead furnace so that the cavities on the bus bar mold are filled with lead liquid, then take out the bus bar mold from the lead furnace, and then invert the battery bottom box equipped with multiple electrode groups on the bus bar mold, so that the electrode ears of multiple electrode groups are inserted into the lead liquid in the cavities on the bus bar mold for casting and welding, and then cool the bus bar mold and take out the battery bottom box from the bus bar mold.

[0003] For example, CN212191190U relates to an intelligent full-automatic casting and welding device for lead-acid battery bus bars. In this device, a lifting water tank is used to cool the bus bar mold. Since the entire bottom of the bus bar mold can be immersed in the water tank during cooling, but each cooling requires lifting and lowering operations on the water tank. When the lifting and lowering speed of the water tank is controlled too fast during this process, it is easy to cause the water surface in the water tank to fluctuate and spill out; if the lifting and lowering speed of the water tank is controlled too slow, it will take a lot of time, reducing the efficiency of the entire casting and welding process. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bus bar casting and welding spray cooling device, which sprays cooling water to the bottom side of the bus bar casting and welding mold through a water spraying pipe during use, thereby completing the cooling of the bus bar casting and welding mold; at the same time, when the water spraying pipe sprays cooling water during use, splashing will occur after hitting the bottom of the bus bar casting and welding mold. In order to prevent the cooling water from splashing into the environment, a circular boss is provided on the bottom side of the water tank, solving the problems raised in the existing background technique.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a bus bar casting and welding spray cooling device, which includes a water tank that moves up and down in the vertical direction through a lifting mechanism.

[0007] Further, a brush structure is provided on the upper surface of the annular boss; when spraying and cooling the bottom of the busbar casting and welding mold, the end of the brush structure is on the bottom side of the busbar casting and welding mold or forms a gap with a height less than 1 cm with the bottom side of the busbar casting and welding mold.

[0008] Further, a return pipe is connected to the bottom side of the water tank located inside the annular boss, and the outlet of the return pipe is directly above the water tank; a water pump is arranged inside the water tank, and the water pump is connected to a water spraying pipe.

[0009] Further, a number of through holes communicating both sides are provided on the bottom side of the annular boss; filter cotton is plugged at the through holes.

[0010] Further, the water spraying pipe is fixed to the bottom side of the water tank through a U-shaped fixing block; the lifting mechanism is selected from a telescopic cylinder or a telescopic oil cylinder.

[0011] The utility model has the following beneficial effects:

[0012] When the utility model is in use, cooling water is sprayed through the water spraying pipe to the bottom side of the busbar casting and welding mold, thereby completing the cooling of the busbar casting and welding mold; at the same time, when in use, the cooling water sprayed by the water spraying pipe splashes after impacting the bottom of the busbar casting and welding mold.

[0020] Please refer to Figures 1 - 3 As shown in the figure, the present invention is a bus bar casting and welding spray cooling device, which includes a water tank 1. A plurality of water spray pipes 10 are fixedly installed on the bottom side surface of the water tank 1 through U-shaped fixing blocks 11, and water spray holes or water spray valves are arranged on the water spray pipes 10. Then, during use, cooling water is sprayed through the water spray pipes 10 onto the bottom side surface of the bus bar casting and welding mold 2, thereby completing the cooling of the bus bar casting and welding mold 2. Finally, the lead on the bus bar casting and welding mold is cooled to form a bus bar.

[0021] At the same time, when in use, the cooling water sprayed by the water spray pipes 10 splashes after hitting the bottom of the bus bar casting and welding mold 2. In order to prevent the cooling water from splashing into the environment, a circular convex platform 12 is arranged on the bottom side surface of the water tank 1, and a plurality of water spray pipes 10 are installed on the bottom side surface of the water tank 1 located inside the circular convex platform 12; when performing spray cooling on the bottom of the bus bar casting and welding mold 2, control the upper surface of the circular convex platform 12 to abut against the bottom side surface of the bus bar casting and welding mold 2, and a gap with a height less than 1 cm is formed between the upper surface of the circular convex platform 12 and the bottom side surface of the bus bar casting and welding mold 2; synchronously, a lifting mechanism is connected to the bottom side surface of the water tank 1, and then during use, the lifting mechanism is used to control the vertical movement of the water tank 1. The lifting mechanism is selected from a telescopic cylinder or a telescopic oil cylinder.

[0022] Based on the above, in order to facilitate the blocking of the splashing cooling water, a brush structure 13 is arranged on the upper surface of the circular convex platform 12; when performing spray cooling on the bottom of the bus bar casting and welding mold 2; the end of the brush structure 13 is on the bottom side surface of the bus bar casting and welding mold 2 or forms a gap with a height less than 1 cm with the bottom side surface of the bus bar casting and welding mold 2.
