Description

Technical Field

[0001] This utility model relates to the field of storage battery processing technology, and in particular to a casting plate forming device for storage battery processing. Background Technology

[0002] The grid is a core component of a lead-acid battery, serving as the current-collecting skeleton structure of the electrodes. It is responsible for conducting current, supporting the active materials, and maintaining electrode stability. Its material is primarily lead-based alloys, including lead-antimony alloys and lead-calcium alloys. Conductivity, corrosion resistance, and mechanical strength are adjusted by adding elements such as antimony, arsenic, and calcium. The manufacturing processes mainly include casting and stretching / grid forming.

[0003] As shown in the reference case "A Gravity Casting Machine for Battery Grids" (publication number CN211965907U), it includes a frame and a chute. The frame is equipped with a grid mold, a lead ladle, and a lead ladle moving structure that moves the lead ladle to pour lead into the grid mold. The grid mold has a casting port. The chute is located below the grid mold. The lead ladle has a heating mechanism. The grid mold includes a fixed mold, a moving mold, and an opening / closing mechanism that drives the moving mold to open and close relative to the fixed mold. The fixed mold and the moving mold are distributed horizontally. The grid cavity and the casting port are both located between the fixed mold and the moving mold. The first objective of this invention is to provide a gravity casting machine for battery grids that can transfer molten lead to the grid mold with the required fluidity without increasing the temperature of the lead melting furnace, solving the problem of high energy consumption associated with existing methods that rely on increasing the temperature of the lead melting furnace to ensure fluidity.

[0004] However, when the aforementioned gravity casting machine is in use, the molten lead in the lead ladle is poured out from the discharge notch to the casting port and enters the grid cavity of the grid mold to form a grid. When the lead ladle is reset, the molten lead will adhere to the notch, resulting in a difference in the amount of molten lead added to the grid cavity. Utility Model Content

[0005] Therefore, it is necessary to provide a casting plate forming device for battery processing to address the problem that when the lead spoon is reset, the lead liquid will adhere to the notch, causing the amount of lead liquid added to the grid cavity to be inconsistent.

[0006] A battery processing plate forming device includes: a support frame, on which a grid mold is mounted, the grid mold including a fixed mold and a movable mold, the movable mold and the fixed mold having grid cavities; a casting mechanism is mounted on the support frame, and a rotating mechanism is installed between the support frame and the casting mechanism; wherein, the casting mechanism includes a lead spoon rotatably connected to the support frame, a liquid outlet hole is opened on one side of the lead spoon near the upper position, a liquid guide pipe connected to the liquid outlet hole is fixedly connected to the surface of the lead spoon, the liquid outlet hole is inclined downwards, and the liquid guide pipe is coaxially arranged with the liquid outlet hole.

[0007] In one embodiment, the top of the lead spoon is provided with a heat-insulating cover, and the surface of the heat-insulating cover has a liquid filling port.

[0008] In one embodiment, a heating tube is fixedly connected to the lower part of the inside of the lead spoon, and a thermostat electrically connected to the heating tube is installed on the bracket.

[0009] In one embodiment, a fixing frame is symmetrically arranged on the surface of the lead spoon on the side near the liquid guide tube, and a collection cover is rotatably connected to the fixing frame. A flow guide cover is fixedly connected to the bottom of the collection cover.

[0010] In one embodiment, the collection hood is wider at the top and narrower at the bottom, and a counterweight is provided on the surface of the flow guide hood.

[0011] In one embodiment, the rotating mechanism includes telescopic cylinders symmetrically arranged on the surface of the support. The lead spoon is rotatably connected to the support, and connecting frames are fixedly connected to both sides of the lead spoon. The connecting frames are rotatably connected to the telescopic end of the telescopic cylinder.

[0012] In one embodiment, the fixed mold of the grid mold is fixed on the support, the moving mold is slidably connected to the support through guide columns, and a mold closing drive device is installed on the support, which is a hydraulic cylinder or an electric push rod.

[0013] In one embodiment, the inner wall of the collection hood is provided with an anti-stick layer, which is a nickel-plated layer or a chromium-plated layer. Beneficial effects

[0014] 1. The above-mentioned casting plate forming device, through the downward and coaxial arrangement of the liquid outlet and the liquid guide pipe, can guide the molten lead to flow out smoothly under the action of gravity, reducing the residue of molten lead in the lead spoon; at the same time, the rotating mechanism drives the lead spoon to rotate stably to achieve quantitative casting. With the guiding effect of the collection cover and the flow guide cover, the molten lead can be accurately introduced into the cavity of the grid mold, effectively avoiding splashing or spilling of molten lead and improving the forming quality of the grid.

[0015] 2. The heat-insulating cover can reduce heat loss from the molten lead in the lead spoon, further stabilizing the temperature of the molten lead. The heating element and the thermostat work together to maintain a suitable temperature for the molten lead, ensuring its fluidity. There is no need to excessively increase the melting temperature of the lead, thus reducing energy consumption and the risk of lead oxidation. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-5 This invention describes a casting plate forming device for battery processing.

[0026] In one embodiment, a battery processing plate forming device includes: a support 100, a grid mold 110 mounted on the support 100, the grid mold 110 including a fixed mold and a moving mold, the moving mold and the fixed mold having grid cavities, a casting mechanism 200 mounted on the support 100, and a rotating mechanism 300 installed between the support 100 and the casting mechanism 200; wherein, the casting mechanism 200 includes a lead spoon 210 rotatably connected to the support 100, a liquid outlet hole 230 opened on one side of the lead spoon 210 near the upper position, a liquid guide pipe 240 fixedly connected to the surface of the lead spoon 210 and communicating with the liquid outlet hole 230, the liquid outlet hole 230 being inclined downward, and the liquid guide pipe 240 being coaxially arranged with the liquid outlet hole 230.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, a heat-insulating cover 220 is provided on the top of the lead spoon 210, and a liquid inlet is provided on the surface of the heat-insulating cover 220. A heating tube 250 is fixedly connected to the lower part of the inside of the lead spoon 210, and a temperature controller electrically connected to the heating tube 250 is installed on the bracket 100. A fixing frame 260 is symmetrically arranged on the surface of the lead spoon 210 near the liquid guide tube 240, and a collection cover 270 is rotatably connected to the fixing frame 260. A flow guide cover 280 is fixedly connected to the bottom of the collection cover 270. The collection cover 270 is wider at the top and narrower at the bottom, and a counterweight is provided on the surface of the flow guide cover 280.

[0028] In this embodiment, the heat-insulating cover 220 effectively reduces heat loss from the molten lead in the lead ladle 210, maintaining a stable temperature. The filling port on its surface facilitates adding molten lead to the ladle 210 while also reducing contact between the molten lead and air during the addition process, thus lowering the probability of oxidation. Molten lead in the lead melting furnace is transported to the lead ladle 210 via a lead delivery pipe. The heating tube 250 is electrically connected to the temperature controller on the support 100, allowing for precise control of the molten lead temperature according to actual needs, ensuring the molten lead maintains good fluidity and preventing poor flow due to low temperature, which could affect the casting effect. The lead ladle 210 is a heat-resistant cast iron ladle. Heat-resistant cast iron has excellent high-temperature resistance; by adding elements such as silicon and aluminum to form a dense oxide film, it effectively resists the corrosion of high-temperature molten lead and reduces the adhesion between the molten lead and the ladle surface.

[0029] The fixing frame 260 is symmetrically arranged on the surface of the lead spoon 210, providing stable support for the collection cover 270. The collection cover 270 is rotatably connected to the fixing frame 260. When the lead spoon 210 rotates, the guide cover 280 rotates around the fixing frame 260 under the action of gravity, so that the collection cover 270 is always perpendicular to the pouring gate of the grid mold 110. The collection cover 270 has a shape that is wider at the top and narrower at the bottom, which is conducive to the collection of molten lead flowing out of the liquid guide pipe 240 and prevents molten lead from splashing everywhere. The bottom of the guide cover 280 is fixedly connected to the collection cover 270. The counterweight block set on its surface uses gravity to ensure that the guide cover 280 maintains a stable posture during the casting process, accurately aligns with the pouring gate of the grid mold 110, and improves the accuracy of molten lead introduction.

[0030] It should be noted that the outlet hole 230 is set at a downward angle of 15°-30° to ensure that the molten lead flows out smoothly under the action of gravity, while avoiding splashing caused by excessively fast flow due to an excessively large angle. It also reduces the possibility of molten lead stagnating in the outlet hole 230 due to an excessively small angle. The inner wall of the outlet hole 230 is finely polished, resulting in a low surface roughness, which effectively reduces the resistance to the flow of molten lead and further reduces the amount of molten lead remaining in the outlet hole 230.

[0031] The liquid guide tube 240 and the liquid outlet 230 are coaxially aligned to ensure that the molten lead flows smoothly and steadily into the liquid guide tube 240 after exiting the liquid outlet 230, preventing splashing or stagnation of the molten lead at the interface. The diameter of the liquid guide tube 240 matches the diameter of the liquid outlet 230, enabling the molten lead to maintain a stable flow rate and direction during flow, accurately delivering the molten lead to the collection hood 270, laying the foundation for subsequent precise casting.

[0032] like Figure 2 and Figure 3 As shown, the rotating mechanism 300 includes telescopic cylinders 310 symmetrically arranged on the surface of the support 100. A lead spoon 210 is rotatably connected to the support 100, and connecting frames 320 are fixedly connected to both sides of the lead spoon 210. The connecting frames 320 are rotatably connected to the telescopic ends of the telescopic cylinders 310. The fixed mold of the grid mold 110 is fixed to the support 100, and the moving mold is slidably connected to the support 100 via guide columns. A mold closing drive device, which is a hydraulic cylinder or an electric push rod, is installed on the support 100. The inner wall of the collection cover 270 is provided with an anti-stick layer, which is a nickel-plated layer or a chromium-plated layer.

[0033] In this embodiment, when the telescopic cylinder 310 extends or retracts, it can drive the lead spoon 210 to rotate flexibly around the rotating connection point with the support 100 via the connecting frame 320, thereby realizing the pouring and resetting of molten lead, and can precisely control the rotation angle to ensure the stability of the casting volume. The fixed mold of the grid mold 110 is fixed on the support 100, and the moving mold is slidably connected to the support 100 through the guide post. The mold closing drive device provides stable power for the movement of the moving mold, ensuring that the moving mold and the fixed mold close precisely, ensuring the sealing of the grid cavity, and preventing molten lead leakage. The nickel-plated or chromium-plated layer on the inner wall of the collection cover 270 serves as an anti-stick layer, with good non-stick and wear resistance, which can effectively reduce the adhesion of molten lead on the inner wall of the collection cover 270, ensure the smooth flow of molten lead, and also facilitate subsequent cleaning and maintenance.

[0034] Working principle: A suitable amount of molten lead is added to the lead ladle 210 through the filling port on the heat-insulating cover 220. The heating tube 250 heats the molten lead under the control of the temperature controller, maintaining the molten lead at a suitable casting temperature. The mold closing drive device is activated, pushing the moving mold along the guide column towards the fixed mold until the moving mold and the fixed mold are tightly closed, forming a closed grid cavity. Subsequently, the telescopic cylinder 310 of the rotating mechanism 300 shortens, driving the lead ladle 210 to rotate around the support 100 via the connecting frame 320. Under the action of gravity, the molten lead in the lead ladle 210 flows into the liquid guide pipe 240 through the downwardly inclined liquid outlet 230. After flowing out of the liquid guide pipe 240, the molten lead enters the collecting hood 270. Under the converging effect of the collecting hood 270, it flows precisely into the grid cavity of the grid mold 110 through the flow guide hood 280. After casting is completed, the telescopic cylinder 310 extends, driving the lead spoon 210 to reset. The mold closing drive device drives the moving mold to separate from the fixed mold, and the formed grid can be taken out, completing one casting process.

[0035] It should be noted that the heating element 250, thermostat, telescopic cylinder 310 and other components mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the heating element 250 and thermostat can be powered by AC mains power. The specific power supply method can be selected according to the situation, which will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
