Abstract

The utility model discloses a comb plate for the production of a lead-acid storage battery. The comb plate comprises a comb plate body; an isolation baffle which is used for preventing burn-in from burning lead parts is arranged on the comb plate body; and the isolation baffle is made of a refractory material. As the isolation baffle is added on the comb plate serving as a burn-in mould to serve as a protective device, no matter the comb plate is operated by green hand or practiced hand, the lead parts can be prevented from being burned during burn-in, thereby effectively improving the welding quality of a busbar and stably improving the quality of the storage battery product.

Description

A kind of comb plate, comb joint of lead acid accumulator production usefulness

Technical field

The utility model relates to lead acid accumulator production field, relates in particular to the comb plate, comb joint that freezes and adopted in the lead acid accumulator production.

Background technology

Positive plate, negative plate and plumbous part are the important component parts of lead acid accumulator.Single lattice capacity of battery is size, thickness by pole plate, and particularly the polar plate number by parallel connection determines; And the voltage of battery is to be determined by the single lattice number that is together in series.This just need put into the mould that freezes to the pole plate for preparing group is on the comb plate, comb joint; With strong flame lug on the pole plate and the rapid scorification of plumbous part base; Fill up lead alloy; Each the sheet positive plate or the negative plate of each utmost point group are connected together (being called bus-bar) with the base of plumbous part is molten; The positive bus of each utmost point group (or negative bus-bar) is cascaded through negative bus-bar (or positive bus) welding of the plumbous part above it and another utmost point group, thereby forms the storage battery that a plurality of single lattice are cascaded.

In the battery on the bus-bar thickness of used plumbous part determined battery to allow the electric current that passes through, if plumbous part is too thin, the internal resistance of cell is bigger than normal, the electric current that battery allows to pass through is too little, is unfavorable for heavy-current discharge especially; If plumbous part is too thick, then cost of idleness.Therefore, the plumbous part of suitable thickness can guarantee cell discharge performance and cost control.Because the welding bus-bar is with strong flame welding, and employee's operative skill there are differences, therefore, the outer core of flame is easy to burn plumbous part in operating process, if burnt plumbous part, needs the cost great amount of manpower to do over again, and causes the wasting of resources.More very; If do not check out the plumbous part of burn; Make it flow to subsequent handling and process finished product, particularly the heavy-current discharge capacity is not enough for its discharge capacity of the lighter, and serious meeting causes the in use inner plumbous part of battery to be blown; Perhaps battery heating is seriously burnt battery and is led to fire, causes direct tremendous economic loss and market negative effect with regard to accumulators manufacturer like this.

The utility model content

The utility model technical problem to be solved is that a kind of comb plate, comb joint of lead acid accumulator production usefulness is provided.

According to the execution mode of the utility model, a kind of comb plate, comb joint of lead acid accumulator production usefulness is provided, comprise the pecten body, be placed with the partitions of the plumbous part of scaling loss that is used to prevent to freeze on the said pecten body, said partitions is that refractory material makes.

Said refractory material is a stainless steel.

Said partitions is that rectangle is tabular.

The dual-side of said partitions is the card base structure, offers the draw-in groove that matches with said card base structure on the said comb plate, comb joint.

Have two card base structures respectively on two opposed side edges of said partitions.

The thickness of said partitions is 1～2mm.

The height of said partitions be said plumbous part height 1/2～1/3.

The length of said partitions is looked the length in the zone of freezing on the said comb plate, comb joint and is decided.

The beneficial effect of the utility model is: through on the mould comb plate, comb joint that freezes, increasing the such protective device of partitions; Operate the plumbous part of burning in the time of to avoid freezing no matter give birth to the skilled worker, thereby improved the welding quality of bus-bar, the stable storage battery product quality that promoted effectively.

Embodiment

Combine accompanying drawing that the utility model is done further explain through embodiment below.

To shown in Figure 5, comb plate, comb joint comprises pecten body 10 among a kind of embodiment like Fig. 1, is placed with the partitions 11 of the plumbous part of scaling loss that is used to prevent to freeze on the pecten body 10.Refractory material is a stainless steel among the embodiment, and employing heatproof steel can be durable in use, can guarantee in the operating process of freezing, to be difficult for crumpling.Partitions is that rectangle is tabular.For conveniently on comb plate, comb joint, accurately locating with light placement and taking out partitions, embodiment comprises the card base structure with the dual-side of partitions, offers the draw-in groove 12 that matches with the card base structure on the comb plate, comb joint, is convenient to place partitions.

Have two card base structures respectively on two of partitions opposed side edges described in a kind of embodiment; With the partitions be rectangle tabular be example; Be similar on rectangular two relative limits and be designed with two card base structures respectively; Certainly, the number of draw-in groove is consistent with the number of card base structure.

Like Fig. 2 and the sketch map for employing partitions in the process of freezing shown in Figure 4, the mould comb plate, comb joint 10 that freezes is sticked on the battery utmost point group 23 that will freeze, put plumbous part 21; Partitions 11 is placed on the comb plate, comb joint through draw-in groove 12; This moment, the top of plumbous part 21 was blocked by partitions 11, and the base of plumbous part flushes with the groove of bus-bar 22, the base and the lug 24 on the battery utmost point group 23 of lead part and fill up lead alloy and be welded together when freezing; And the top of plumbous part 21 is owing to blocked by partitions 11; Do not burnt, thereby, adopt partitions can protect plumbous part not burnt well.

Among the embodiment, the thickness of partitions can be 1～2mm, and its length is looked the length in the zone of freezing on the comb plate, comb joint and decided, and for protecting plumbous part, the height of partitions can be 1/2～1/3 of the height of plumbous part.

Like Fig. 5 and shown in Figure 6, be on anodal comb plate, comb joint and negative pole comb plate, comb joint, respectively to put a partitions, thereby can prevent plumbous part on anode plate and the negative plates in the process of freezing not by flame burn.

Present embodiment adopts partitions to block plumbous part through the plumbous part of optimal design scaling loss when preventing to freeze, the plumbous part of avoiding burning, and partitions adopts the heatproof steel, and is durable in use, can guarantee in the operating process of freezing, to be difficult for crumpling; In addition, place partitions, on comb plate, comb joint, offer draw-in groove, and the card base structure is processed at two of baffle plate, make it make things convenient for locator card on comb plate, comb joint for ease of accurately locating.

Above-mentioned execution mode is giving an example of the utility model; Although disclose the preferred forms and the accompanying drawing of the utility model for the purpose of illustration; But it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and appended claim, various replacements, variation and modification all are possible.Therefore, the utility model should not be limited to preferred forms and the disclosed content of accompanying drawing.
