Description

Manifold casting and welding device for lead-acid battery

technical field

The utility model relates to a casting and welding device for a confluence plate connected with a metal pole plate of a battery.

Background technique

A lead-acid battery usually has an electrode group consisting of several positive plates and several negative plates. The positive plate lugs and the negative plate lugs in the electrode group are respectively connected through a manifold, and then connected to the positive and negative terminals. In the manufacture of lead-acid batteries, the traditional method of connecting the pole plate and the manifold is manual welding. This method is labor-intensive, low in efficiency, unreliable in quality, and pollutes the operating environment and seriously damages human health. For this reason, some enterprises have developed a special casting and welding device for the pole plate and the manifold. For example: the patent No. is CN200720149023.4's "small dense casting and welding machine", which includes a shaping machine, earphone cutting, lead melting furnace, cooling machine and demoulding and boxing machine connected in sequence by a belt. Another example is the "medium-density casting and welding machine" whose patent number is CN200720147929.2. It includes a shaping device, an ear cutting device, a casting and welding device, a demoulding device and a casting and welding box. The focus is to have a four-position casting and welding bracket The lower end of the cast-welding bracket is connected to the driving rotation device through a rotating shaft, and several casting-welding boxes are arranged at the upper end. Azimuthally, the cast-welding rotary bracket is connected to the cast-weld box through the above-mentioned shaping device, ear-cutting device, casting-welding device, demoulding device, etc., to complete the whole process. The above-mentioned patents all realize the mechanization or semi-mechanization of casting and welding of the pole plate and the manifold, effectively solving the problems of high labor intensity, low work efficiency and large environmental pollution of the original manual welding. However, there are still problems in both of which need to further improve work efficiency, reduce energy consumption and production costs. For example, the former has problems such as slow air cooling speed, high energy consumption, many turnover molds, and high production costs; the latter has problems such as casting Welding to stripping only takes one station, that is, only rotates 90 ^° , so the cooling time is insufficient, and it is necessary to wait for cooling at the stripping station, which affects work efficiency and output.
