Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery casting and welding technology, and in particular relates to a lead supply device for casting and welding molds. Background Technology

[0002] Traditional battery casting and welding equipment involves immersing the casting mold in molten lead for heating. This method has the following problems: 1. A large amount of lead is required to completely submerge the mold. Maintaining a constant temperature for the molten lead requires high energy consumption. 2. Repeated heating and cooling and frequent stirring of the lead pot during the casting and welding process increase the contact area between the molten lead and air, making it prone to oxidation and forming lead slag, which affects the casting and welding effect and results in a high lead slag rate. Utility Model Content

[0003] The purpose of this utility model is to provide a lead supply device for casting and welding molds. By changing the original method of immersing the mold in the lead pot to allow the lead to flow into the manifold from the bottom of the lead pot by gravity, and changing the lead discharge method to discharge from the bottom, the lead oxide slag on the surface in contact with the air has a smaller impact on the casting and welding effect. In addition, there is less movement on the surface of the lead liquid, and the protective film formed by the lead oxide slag prevents the lead liquid from being repeatedly oxidized, thereby reducing lead slag and solving the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a lead supply device for casting and welding molds, comprising a lead pot and a heater disposed inside the lead pot; an opening is formed on the bottom side of the lead pot, and an L-shaped lead drain pipe is inserted through the opening; a flow channel A is provided in the vertical section of the L-shaped lead drain pipe, and a valve cavity is provided in the horizontal section of the L-shaped lead drain pipe; a flow channel B communicating with the valve cavity is provided at the bottom end of the flow channel A; a plug ball and a drain port are provided in the valve cavity near the flow channel B; a valve sleeve is provided inside the valve cavity, and a valve stem is provided on the valve sleeve.

[0006] Furthermore, the valve stem is a ceramic valve stem, and the ceramic valve stem and the valve sleeve are fitted with a guide seal; the plug ball is a ceramic ball.

[0007] Furthermore, one end of the L-shaped lead drain pipe protrudes from the inner bottom side of the lead pot and is threadedly connected to a nut whose end rests against the inner bottom side of the lead pot.

[0008] Furthermore, a U-shaped frame is fixed to one end of the lead pot, and a crossbar is connected between the two inner side walls of the U-shaped frame; a telescopic cylinder is installed on the U-shaped frame, a movable rod is connected to the end of the telescopic cylinder, a connecting block is connected to the end of the movable rod, and the valve stem is connected to the connecting block.

[0009] Furthermore, a guide rod is provided at the end of the movable rod, and a through hole for inserting the guide rod is provided on the connecting block; a spring is connected between the movable rod and the connecting block.

[0010] This utility model has the following beneficial effects:

[0011] This invention changes the process from immersing the mold in the lead pot to allowing the lead to flow into the manifold from the bottom of the pot by gravity; the lead discharge method is also changed to discharge from the bottom. The lead oxide slag on the surface that is in contact with the air has less impact on the casting and welding effect, and there is less movement on the surface of the lead liquid. The protective film formed by the lead oxide slag prevents the lead liquid from being repeatedly oxidized, thereby reducing lead slag.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Please see Figure 1-3As shown, this utility model is a lead supply device for casting and welding molds, including a lead pot 2. The lead pot 2 contains a heater 20 for heating molten lead, and an opening 27 is formed on the bottom side of the lead pot 2. An L-shaped lead pipe 3 is inserted through the opening 27. During use, as... Figure 1-2 As shown, the lead pot 2 is positioned above the casting mold 1, and the molten lead in the lead pot 2 is injected into the casting mold 1 through the L-shaped lead discharge pipe 3.

[0020] In order to control the flow of the L-shaped lead drain pipe 3 as needed during use, this application provides a flow channel A34 inside the vertical section of the L-shaped lead drain pipe 3, and a valve chamber 32 inside the horizontal section of the L-shaped lead drain pipe 3. A flow channel B35 connecting the valve chamber 32 is provided at the bottom end of the flow channel A34, and a plug ball 36 and a drain port 37 are provided in the valve chamber 32 near the flow channel B35. A valve sleeve 33 is provided inside the valve chamber 32, and a valve stem 38 is provided on the valve sleeve 33. In use, by controlling the movement of the valve stem 38, the plug ball 36 can be moved away from or closer to the flow channel B35 by the gravity of the lead liquid and the action of the valve stem 38, thereby controlling the flow of the L-shaped lead drain pipe 3.

[0021] Specifically, the ball 36 is a ceramic ball, and one end of the L-shaped lead drain pipe 3 protrudes from the inner bottom side of the lead pot 2 and is threadedly connected to a nut 31 whose end rests against the inner bottom side of the lead pot 2.

[0022] Based on the above, in order to control the horizontal movement of the valve stem 38, a U-shaped frame 21 is fixed to one end of the lead pot 2, and a crossbar 22 is connected between the two inner side walls of the U-shaped frame 21; a telescopic cylinder 23 is installed on the U-shaped frame 21, and a movable rod 24 is connected to the end of the telescopic cylinder 23, and a through hole is provided on the crossbar 22 for the movable rod 24 to pass through. A connecting block 26 is connected to the end of the movable rod 24, and the valve stem 38 is connected to the connecting block 26. Thus, during use, the conduction of the L-shaped lead pipe 3 is controlled by the extension and retraction of the telescopic cylinder 23.

[0023] Specifically, the heater 20 installed inside the lead pot 2 heats the lead particles and stops heating when the specified temperature is reached. At the same time, when the mold moves to the specified position, the telescopic cylinder 23 retracts, and the L-shaped lead discharge pipe 3 is opened, thus starting the quantitative addition of lead. Meanwhile, according to the specifications and dimensions of the manifold, the mold is controlled to move, and the opening and closing time of the lead outlet is adjusted according to actual needs.

[0024] In one possible implementation, a guide rod is provided at the end of the movable rod 24, and a through hole for inserting the guide rod is provided on the connecting block 26; a spring 25 is connected between the movable rod 24 and the connecting block 26; the valve stem 38 is a ceramic valve stem, and the ceramic valve stem and the valve sleeve 33 adopt a matching guide seal. The sealing assembly of the ceramic valve stem 38 and the ceramic plug ball 36 maintains stable sealing performance in the high temperature lead liquid environment. The guide rod structure with spring 25 buffer makes the valve opening and closing process smooth and shock-free.
