Abstract
The invention provides a method for manufacturing a positive grid of a lead-acid storage battery. After the gravity casting and forming of the grid and before cutting, the grid is integrally stamped; during casting, the thicknesses of all parts of the grid are controlled to be consistent; during stamping, horizontal rods, longitudinal rods and an outer frame are stamped from a prismatic section structure into a drum type section structure at the same time. The method is used for manufacturing the positive grid of the lead-acid storage battery for floating standby, the consistency of grid alloy can be increased, the corrosion resistance is increased, and the service life of the batteries is prolonged.
Description
Technical field
The present invention relates to a kind of positive grid of lead-acid accumulator manufacture method, belong to lead acid accumulator and make the field.
Background technology
Grid is the important component part of lead acid accumulator, plays the support active material, serves as the carrier of active material, and the effect of conduction current is evenly distributed on the active material electric current.Industrial lead acid accumulator plate grid is made and mainly is divided three classes: first gravity casting, capital equipment are casting plate machine and corresponding supporting grid mould.Adopt the grid of gravity casting moulding, its thickness can not be thin excessively, can not be the modal grid manufacturing technology of present industrial lead acid accumulator less than 1.5mm usually.Form because grid adopts gravity casting, the grid alloy crystal formation is not fine and close, easily corrosion.It two is continuous casting grids, and capital equipment is conticaster, and grid adopts continuous casting process, generally is not used in positive grid manufacturing.It three is that tandem rolling connects the punching grid, and such slab lattice thickness is thinner, and thickness is not generally selected as the storage battery of floating charge stand-by power supply below 1.5mm usually.And as the standby industrial storage battery of floating charge, it is modal to cause that the reason of battery malfunction is exactly positive grid corrosion.The positive grid of existing floating charge standby lead-acid battery adopts the gravity casting manufacture method, and is not corrosion-resistant, influences performance and the life-span of battery.
Summary of the invention
The objective of the invention is to overcome the weak point in the existing gravity casting method, provide a kind of lifting positive grid decay resistance, prolong the battery positive grid of lead-acid accumulator manufacture method in useful life.
Technical scheme of the present invention is: the positive grid of lead-acid accumulator manufacture method, comprise grid gravity casting and cut, its improvements are after gravity casting, grid are carried out whole punching press, the transverse rod strip of control board grid, vertical rib strip and housing consistency of thickness during gravity casting before cutting.
Described whole punching press is to adopt stamping die on pressing equipment transverse rod strip, vertical rib strip and the housing of grid to be struck out the cydariform cross section structure by prismatic cross section structure simultaneously, and the thickness after the punching press reduces 0.15mm～0.25mm before than punching press.
Among the present invention, after gravity casting is shaped, grid is carried out whole punching press handle, improved the density of grid alloy, promoted corrosion resistance, and then extending battery life.Guarantee grid each several part consistency of thickness during gravity casting, be convenient to punching press, can make density uniformity after the punching press; The cydariform cross section structure that forms after the punching press is conducive to further strengthen corrosion resistance and the intensity of transverse rod strip, vertical rib strip and housing.
Description of drawings
The positive grid structural representation that Fig. 1 makes for the present invention.
Fig. 2 is A-A place generalized section among Fig. 1.
Fig. 3 is B-B place generalized section among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing 1,2,3, further specify the embodiment of the invention.
Positive grid of lead-acid accumulator is made of housing 1, vertical rib strip 2, transverse rod strip 3 and lug 4, its manufacture method is: at first make semi-finished product by the lead alloy gravity casting of routine, the consistency of thickness of the transverse rod strip of control board grid, vertical rib strip and housing is dmm during casting.Then carry out whole punching press, adopt stamping die on pressing equipment, longitudinal and transverse rib and the housing of grid to be struck out the cydariform cross section structure by prismatic cross section structure simultaneously, the thickness in the thickness in housing cross section 5 and vertical rib strip cross section 6 is d-0.2mm after the punching press, and the transverse rod strip section thickness too.Cut with cutting knife at last, the grid saliva material in the casting cycle is excised.
Claims (2)
1. positive grid of lead-acid accumulator manufacture method comprises the gravity casting of grid and cuts, and it is characterized in that after gravity casting, grid is carried out whole punching press, the transverse rod strip of control board grid, vertical rib strip and housing consistency of thickness during gravity casting before cutting.
2. positive grid of lead-acid accumulator manufacture method according to claim 1, it is characterized in that: described whole punching press is to adopt stamping die on pressing equipment transverse rod strip, vertical rib strip and the housing of grid to be struck out the cydariform cross section structure by prismatic cross section structure simultaneously, and the thickness after the punching press reduces 0.15mm～0.25mm before than punching press.
