Flat cut type plate-casting machine

Abstract

The invention relates to a truncated slab casting machine, in particular to a lead alloy slab lattice casting and forming device for manufacturing a lead-acid accumulator. The lead alloy slab lattice casting and forming device comprises a production line device which is formed by connecting a high-level lead smelting furnace, a tandem lead valve gear, a lead scoop lead turnover mechanism, a die switching die mechanism, a reshaping and conveying mechanism, a slab lattice horizontal positioning mechanism, a truncated cutting-knife die, a slab lattice receiving mechanism and a circulating water tank in sequence. The device is cooperatively operated under automatic electric control. The truncated slab casting machine adopts the tandem lead valve gear, the slab lattice horizontal positioning mechanism and the truncated cutting-knife die, is accurate to quantitatively supply lead and convenient to replace valve cores, makes lead alloy slab lattices horizontally positioned on a lower positioning plate at a uniform velocity to realize non-deformation of the lead alloy slab lattices, realizes automatic casting forming of the lead alloy slab lattices, completes transformation of the production flow from manual labor to automatic operation, greatly reduces the production strength and the operation cost of manual operation, guarantees the casting quality of quantitative and accurate supply of the leads, convenient replacement of the valve cores and non-deformation of the lead alloy slab lattices, and improves the labor productivity.

Description

technical field [0001] The invention relates to lead alloy grid casting equipment in the manufacture of lead-acid batteries, in particular to a flat-cut casting machine for producing lead alloy grids of lead-acid batteries. Background technique [0002] In the production process of lead-acid batteries, it is necessary to produce lead alloy grids with qualified dimensions, and the lead alloy grids are mainly produced by casting machines. The casting machine includes a high-level lead melting furnace (or a low-level lead melting furnace), a lead valve device, a lead spoon pouring mechanism, a mold opening and closing mechanism, a shaping and conveying mechanism, a grid slope positioning mechanism, an inclined cutter mold, and a grid Take-up mechanism and circulating water tank. [0003] At present, there are two kinds of known lead valves: a kind of lead valve is a cone-tip cone-face sealing valve exposed to the air. Lack of sealing leads to lead leakage and inaccurate quant...

Problems solved by technology

[0003] At present, there are two kinds of known lead valves: a kind of lead valve is a cone-tip cone-face sealing valve exposed to the air. Lack of sealing leads to lead leakage and inaccurate quantitative lead supply; another kind of lead valve is a ceramic ball cone sealing valve embedded in the lead liquid. The valve core of this lead valve is installed in the pump body and locked with the valve core gland. When replacing the spool, the lead pipe and the whole lead pump must be unloaded first, and it is difficult to replace the spool

[0004] At present, the known cutting dies all use an angle of about 40-50° to cut off the process gate of t...
