Description
Technical field
The utility model belongs to the cast welding technical field of battery metal polar plate or analog, particularly a kind of accumulator plate cast welded mold.
Background technology
Most batteries all is made of plastic casing and several cells that are mounted in it, and each cell replaces closed assembly by positive plate and negative plate again and forms, and the all-glass paper with some layers of insulation between positive plate and negative plate separates.Several positive plate lugs on the battery cell and several negative plate lugs form long positive bus and the negative bus that pole is arranged by cast welding technique respectively, and then successively the positive and negative pole of adjacent monomer battery is welded with the method for electric welding, thereby form the battery pack that is in series by several cells.
Wherein, with positive pole ear and negative lug respectively cast welding to become the operation of bus-bar be very important in battery production, the welding quality of lug and metal cast welding liquid directly affects performance and the life-span of battery in this operation.The battery cell two ends are respectively some positive pole ears and some negative lug, and the chemical composition of positive pole ear is the Pb-Sb-Cd alloy, and the chemical composition of negative lug is the Pb-Sn alloy, and the structural representation of positive pole ear and negative lug as shown in Figure 1.In current technology, the mould of cast welding positive pole ear and negative lug as shown in Figure 2, Fig. 3 be among Fig. 2 A-A to cutaway view.As we can see from the figure: on four angles of die ontology (1) locating hole (7) is set respectively, die ontology (1) each side be provided with 6 collecting traies (3), be provided with a pole hole (4) in each collecting tray (3), collecting tray (3) is used for the some positive pole ears (61) on the battery cell or negative lug (62) cast welding together, and respectively grows a pole.Processing step is: (1) is fixed 6 battery cell battery lead plates with anchor clamps; (2) mould is stretched in the molten state metal cast welding liquid, take out mould after metal cast welding liquid fills with collecting tray and pole hole, the flat limit scraper plate made from exotic material strikes off die face; (3) the battery cell battery lead plate inversion that is fixed together is come to aim at corresponding locating hole and collecting tray insertion mould, positive pole ear and negative lug are inserted respectively in the cast welding liquid of corresponding collecting tray; (4) etc. slough mould and anchor clamps after metal cast welding liquid solidifies, more inverted battery is turned, just form respectively positive bus and pole, negative bus-bar and pole on each battery cell this moment; (5) successively the positive and negative pole of adjacent monomer battery is welded with the method for electric welding at last and form the battery pack that is in series by several cells (be together in series obtain the batteries that voltage is 12V such as the battery cell with 6 2V).
In the prior art, do not consider the difference of positive plate and negative plate chemical composition, disposable cast welding forms positive and negative bus-bar and pole to lug to adopt same mould and same molten state metal cast welding liquid.Because the chemical composition of positive plate and lug is different, and the metal cast welding liquid that adopts composition is identical, this easily causes lug and metal cast welding liquid to solidify between the bus-bar alloy of formation and slot and shrinkage hole occur, and then causes lug and bus-bar weld seam to break.In valve control type sealed cell, the battery upper space usually has been full of oxygen (coming from the decomposition of water), and the electrolyte in the dividing plate swashes to bus-bar along lug, causes the bus-bar alloy oxidation and forms PbSO
4(being commonly called as sulfation).Along with the continuous intensification of this oxidation or corrosion, the slot between lug and the bus-bar or crack be aggravation constantly, causes at last lug and bus-bar to be thrown off, and battery is scrapped.
The utility model content
The purpose of this utility model is to overcome deficiency or the defective that exists in the existing cast welding operation, a kind of accumulator plate cast welded mold is provided, this mould can be strengthened the compactness of combination between positive pole ear or negative lug and the bus-bar, reduces the structural slot between positive pole ear or negative lug and the bus-bar.
The scheme that the utility model solve the technical problem is: a kind of accumulator plate cast welded mold, comprise body and the handle that is arranged on the body, some collecting traies are set on the body, the pole hole is set in the collecting tray, described body is anodal template and the negative template that 2 splits arrange, the hollow-out parts that runs through all is set on anodal template and the negative template, collecting tray and hollow-out parts on anodal template and the negative template laterally are arranged alternately, collecting tray and hollow-out parts on anodal template and the negative template vertically are arranged alternately, the position opposite of collecting tray and hollow-out parts on the position of collecting tray and hollow-out parts and the negative template on the anodal template.
During use, different for the chemical composition of positive pole ear and negative lug, prepare 2 kinds of different metal cast welding liquid that form.Scoop out the metal cast welding liquid that forms preparation for positive pole ear with anodal template first, because the position that original negative lug is inserted into has become the hollow-out parts that runs through, contain incessantly metal cast welding liquid in it, after the battery cell that is fixed together fallen to insert anodal template, only have the positive pole ear place just to form bus-bar and pole, after solidifying, the bus-bar at positive pole ear place and pole take off anodal template, scoop out the metal cast welding liquid that forms preparation for negative lug with negative template again, because the position that original positive pole ear is inserted into has become the hollow-out parts that runs through, contain incessantly metal cast welding liquid in it, the battery cell that is fixed together is being fallen behind the insertion negative template, only have the negative lug place just to form bus-bar and pole, the bus-bar at the positive pole ear place that has formed and pole then stretch in the hollow-out parts that negative template runs through.The utility model has made an original mould into two, the producer can be formed for different lugs adopt corresponding different cast welding liquid, thereby can strengthen compactness and the fastness of combination between positive pole ear or negative lug and the bus-bar.
As improvement, 1 collecting tray and 1 hollow-out parts laterally respectively are set on described anodal template and the negative template, 2 row collecting tray and hollow-out parts vertically respectively are set on anodal template and the negative template, every row arrange 3 collecting traies and 3 hollow-out parts.
This scheme is mainly used in the production of 12V battery.
As improvement, the periphery of described anodal template and negative template arranges locating hole.
Locating hole guarantees that positive pole ear and negative lug can accurately enter collecting tray or hollow-out parts.
As improvement, described hollow-out parts is the hole of rectangle.
In sum, the utility model forms positive bus and pole, negative bus-bar and pole with the secondary cast welding, can look after the structure difference of positive pole ear and negative lug, can effectively reduce the structural slot between lug and the bus-bar, optimize accumulator property, prolonging service life of battery.
