Embodiment Construction

[0020] see figure 1 , a continuous casting and rolling grid structure, comprising an upper frame 2 and a lower frame 3, the two ends of the upper frame 2 and the lower frame 3 are connected by a vertical frame 4 to form a rectangular frame, and a plurality of vertical ribs 5 are arranged inside the rectangular frame, The vertical ribs 5 and the vertical frame 4 are parallel to each other, and the upper frame 2 is also provided with tabs 1 . The width of one end of the tab 1 close to the upper frame 2 is greater than the width of the other end; not only can it ensure reliable welding, but also can save materials; the width of the tab 1 is 4 to 10 mm, and the thickness of the tab 1 is 0.5 to 2 mm. The width of the upper frame 2 is 2 to 4 mm, and the thickness of the upper frame 2 is 0.5 to 2 mm; the width of the lower frame 3 is 1.5 to 3 mm, and the thickness of the lower frame 3 is 0.5 to 2 mm; the width of the vertical frame 4 is 2 to 4 mm, and the vertical frame 4 The thickn...

Abstract

The invention provides a continuous casting and rolling grid structure, and particularly relates to the field of battery devices. The continuous casting and rolling grid structure comprises an upper frame and a lower frame, two ends of the upper frame and two ends of the lower frame are connected through vertical frames to form a rectangular frame, a plurality of vertical ribs are arranged in therectangular frame, the vertical ribs are parallel to the vertical frames, and the upper frame is further provided with tabs. The battery capacity can be improved, the service life of the battery can be prolonged, and the production material cost can be reduced.

Description

technical field [0001] The invention belongs to the field of battery devices, and in particular relates to a continuous casting and rolling grid structure. Background technique [0002] The grid is the main component of the lead-acid battery. It is the current collector skeleton of the electrode, which conducts, collects and distributes the current evenly. At the same time, it supports the active material and is the carrier of the active material; the grid is the lead-acid battery. The main components, there are two kinds of stretching and casting. Casting is to pour the heated and melted lead alloy into the grid mold under the action of gravity, then cool and form it, and then process it. Expanded grid is to make a predetermined rectangular hole on a punch with a lead belt of a certain width, and then stretch it; but there are two kinds of grids produced by two processes, and the grid is composed of horizontal ribs and vertical ribs; this kind of structure exists There ar...
