Description

Technical Field

[0002] During the lead ingot casting process, the molten lead liquid needs to be divided into several forming molds. The several forming molds are arranged in sequence between two conveyor chains on a conveyor frame. A motor drives the two conveyor chains in a circular transmission and drives the forming molds to move. The lead liquid is then poured into each forming mold through a lead liquid conveying pipe located above the conveyor chain on one side. Since the lead liquid in the lead liquid conveying pipe is in continuous flow, some of the lead liquid will be poured onto the top of the partition between two adjacent forming molds, resulting in waste of lead liquid. This part of the lead liquid needs to be recycled and reprocessed, increasing production costs. Therefore, it is urgently necessary to propose a metal smelting planetary gravity casting lead liquid distribution device to solve this technical problem. Utility Model Content

[0024] like Figure 1As shown, a planetary gravity casting lead liquid distribution device for metal smelting includes a frame 1, two conveyor chains 2 located on both sides of the upper end of the frame and parallel to each other, and a distributor 3 located above one of the conveyor chains and rotatably connected to the frame. A number of forming molds 4 are arranged in sequence between the two conveyor chains along the conveying direction. The conveyor chain is driven by a motor, and its circular transmission drives the forming molds forward. The distributor is connected to a driving component that drives it to rotate. The driving component is connected to the conveyor chain. The conveyor chain drives the distributor to rotate synchronously through the driving component, so that the diversion pipe and the forming mold are matched one by one to realize the packaging of the lead liquid. Figure 2 As shown, the distributor is a horizontal hollow cylindrical structure, and a plurality of diverter pipes 5 distributed in a circular array and inclined toward the outside of the circumference are provided on the side facing the forming mold. The distance between two adjacent diverter pipes matches the width of each forming mold. The number of diverter pipes in this embodiment is eight. An end cover 6 with a liquid inlet 601 in the middle is provided on the other side of the distributor. A liquid inlet pipe 7 connected to the inside of the distributor is provided on one side of the liquid inlet. The diameter of the liquid inlet pipe is smaller than the inner diameter of the liquid inlet. The molten lead enters the distributor through the liquid inlet pipe. Two pressure wheels 8 for supporting the distributor are rotatably connected to the frame. The two pressure wheels are symmetrically distributed on both sides of the bottom of the distributor. The distributor is placed on the two pressure wheels, and the distributor is driven to rotate at the upper end of the two pressure wheels by the transmission chain through the drive assembly. The two pressure wheels can effectively ensure the stability of the distributor's rotation.

[0025] Combine Figure 1 and Figure 2 As shown, the drive assembly includes a drive shaft 9, a sprocket 10 and a mounting seat 11. One end of the drive shaft is connected to the distributor, and the other end is rotatably connected to the mounting seat provided on the frame. The sprocket is provided on the drive shaft and is connected to the conveying chain away from the distributor, so that the rotation speed of the distributor is synchronized with the conveying speed of the forming mold. The drive shaft includes a driven shaft 901, a driving shaft 902 and a universal coupling 903. The driving shaft is connected to the universal coupling, and the universal coupling is connected to the driven shaft. The setting of the universal coupling can effectively avoid the situation where the distributor and the sprocket are not on the same central axis during installation, resulting in unstable transmission. Figure 3As shown, the universal coupling includes a connecting seat 9031, a movable cover 9032 and a ball head 9033. The interior of the connecting seat is provided with a cavity 90311 with a semicircular vertical cross-section. One side of the movable cover is provided with an arc-shaped groove 90321 that matches the ball head and is threadedly connected to the connecting seat. A through hole 90322 is opened in the middle of the other side. The diameter of the through hole is smaller than the diameter of the ball head and larger than the diameter of the driving shaft. The ball head is provided in the cavity and the groove, and the side away from the cavity is embedded in the through hole and connected to the driving shaft. The movable cover and the connecting seat are detachable, which is convenient for the installation of the universal coupling. When the movable cover is not completely tightened, the ball head can rotate and swing freely in the cavity and the arc-shaped groove to achieve universal adjustment. In order to further facilitate the disassembly and assembly of the drive shaft, the driven shaft and the distributor are connected by screw assembly, combined with Figure 4 As shown, the active shaft includes a first shaft rod 9021, a second shaft rod 9022 and a plug-in sleeve 9023. One end of the first shaft rod is connected to the ball head, and a limit strip 90211 is provided on the surface of the other end. One end of the second shaft rod is connected to the sprocket, and the other end is connected to the plug-in sleeve. A limit groove 90231 is provided inside the plug-in sleeve to cooperate with the limit strip. The first shaft rod and the plug-in sleeve can be plugged in to achieve disassembly and assembly, and the operation is simple and convenient.

[0026] The working principle of this utility model is as follows:

[0027] like Figures 1 to 4 As shown, the lead liquid is transported to the distributor 3 by the liquid inlet pipe 7 at a constant flow rate, so that the liquid level of the lead liquid in the distributor 3 is maintained at a constant height, that is, the inflow of the lead liquid in the distributor 3 is balanced with the flow rate. When the conveyor chain 2 is transporting the forming mold 4, the distributor 3 rotates synchronously, and the diverter pipe 5 and the forming mold 4 correspond one to one to transport the lead liquid. When any forming mold 4 is located directly below the distributor 3, only one diverter pipe 5 has lead liquid flowing out and pours the lead liquid into the forming mold 4, and the diverter pipe 5 is located directly below the distributor 3; when the partition between two adjacent forming molds 4 is located directly below the distributor 5, the two diverter pipes 5 on both sides of the partition discharge liquid synchronously, thereby effectively ensuring the accurate packaging of the lead liquid, reducing the waste of lead liquid, and saving costs.

[0028] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive.
