Continuous casting machine for lead plate of lead-acid storage battery

Abstract

The invention discloses a continuous casting machine for a lead plate of a lead-acid storage battery, comprising a molten lead infusing device, a rolling device, a fixing support table and a cooler; the molten lead infusing device comprises a movable lead spoon, a heating tube, a molten lead output tube, a rotational arm, a guide groove, a guide shaft, a movable bearing and a driving device; the guide groove is arranged on the guide shaft movably; the rotational arm is arranged on the rotational shaft of the driving device; one end of the rotational arm is arranged in the guide groove throughthe movable bearing; the other end of the rotational arm is connected with the movable lead spoon; the movable lead spoon is internally provided with the heating tube and the molten lead output tube for feeding molten lead; the molten lead infusing device and the rolling device are arranged on the fixing support table; the movable lead spoon of the molten lead infusing device is installed above the roller of the rolling device; the movable lead spoon is driven to move above the roller repeatedly by the rotational arm driven by the driving device; and the cooler is communicated with the inner cavity of the roller of the rolling device. Molten lead is uniformly fed into the continuous casting machine for the lead plate through a reciprocating method, thereby ensuring the quality of the leadplate.

Description

Technical field [0001] The invention relates to a continuous casting machine, in particular to a lead plate continuous casting machine for lead-acid batteries. Background technique [0002] The main function of the grid in a lead-acid battery is to conduct and collect current on the one hand, and to make the current distribution uniform, on the other hand, to support active materials. The grid is both a conductive framework and a dual function of an active material carrier. Therefore, the grid has certain mechanical, electrical, and metallurgical characteristics. That is, the grid is required to have good mechanical properties (including hardness, tensile strength, casting performance, weldability), good corrosion resistance and good electrical conductivity. [0003] At present, the main methods of making lead-acid battery grids include drawing, continuous casting and rolling, gravity casting and forging strip expansion, casting expansion and stamping and punching rolling, etc. Th...

Problems solved by technology

[0005] At present, the continuous casting machine for manufacturing lead plates for grids uses the method of adding lead liquid at a fixed position, which cannot achieve uniform addition of lead liquid. Due to the defects of this lead liquid adding method, the manufactured lead plates have poor uniformity and rough edges. Many, inconsistent thickness, inconsistent mechanical strength and other shortcomings, the prepared grid cannot meet the performance and service life requirements of the lead-acid battery for the grid
