Description
Technical field
The present invention relates to lead acid accumulator plate grid process technology, particularly relate to a kind of one time punching molded lead acid accumulator plate grid and manufacture method thereof.
Background technology
In the last few years, along with improving constantly of Lead-acid Battery Technology, lead acid accumulator has become the most widely used chemical power source.Lead acid accumulator is also the core component of the large-scale redundant electrical powers such as electric power system peak regulation accumulation power supply, back-up source, internal combustion engine accumulation power supply, the development of lead acid accumulator industry and closely bound up with its supporting above-mentioned industry, and coexist in the national economic development with these industries one and played important function.
Although at present lead acid accumulator is still the main flow battery in battery industry, also there is self deficiency, the series of problems such as such as electrode plate grid corrosion resistant is indifferent, cycle life is poor in it.And the manufacture method of grid has direct impact to above-mentioned phenomenon.When raw material is identical, grid manufacturing process directly affects corrosion resistant ability and the useful life of battery.Grid manufacturing process that developed at present, that find broad application, mainly comprises gravitational casting, continuous casting grid continuous rolling, continuous casting. g., lead tape expands net, the continuous punching of continuous casting. g., lead tape continuously.But when producing lead acid accumulator plate grid, although the technique of the casting grid that can obtain stabilized structure due to its corrosion resistant ability poor, often need the larger grid of casting thickness could meet battery life requirement; Although and it is good to expand web plate grid corrosion resistance, low cost of manufacture, is often easily out of shape owing to not having outer rim, causes the early stage short-circuit failure of battery; And the continuous rolling grid of continuous casting is often because shaping grid surface is too smooth, and slab lattice thickness is limited, and lead plaster lotion adhesive force is reduced, and occurs the phenomenon that lotion comes off.So how to make pole plate while thinner good corrosion resistance, have better adhesive force to lead plaster lotion, becoming the art has problem to be solved.
After now existing relevant processing method is continuous casting continuous rolling. g., lead tape technique, punching is carried out to. g., lead tape, make the punching grid that thickness is consistent with. g., lead tape substrate thickness, finally extrusion modling is carried out to grid, punching and extruding two techniques are separately carried out by the method, waste punching grid remaining mould kinetic energy in punch process, and two molds will be prepared, operate at twice, therefore, the method reduces the working (machining) efficiency of grid on the one hand, turn improves the manufacturing cost of grid on the other hand.
Summary of the invention
The present invention is intended to solve above-mentioned problems of the prior art, proposes a kind of one time punching molded lead acid accumulator plate grid and manufacture method thereof.
One aspect of the present invention proposes a kind of one time punching molded lead acid accumulator plate grid, comprise lug, grid skeleton and grid, described grid comprises many horizontal, vertical ribs, described horizontal, vertical rib is intertwined to form rib net, described perpendicular rib protrudes from described grid substrate, and described perpendicular rib and described grid substrate are staggered.
The present invention proposes a kind of manufacture method of one time punching molded lead acid accumulator plate grid on the other hand, comprises the following steps: step one, is positioned between the punch forming dynamic model of punch-forming mold and the quiet mould of punch forming by location by grid to be processed; Step 2, controls described punch forming dynamic model to described grid punching press, punches out grate opening and horizontal, vertical rib; Step 3, controls described punch forming dynamic model and draws close to the quiet mould of described punch forming gradually, continuously extruded described horizontal, vertical rib; Step 4, controls described punch forming dynamic model and closes up completely with the quiet mould of described punch forming gradually, makes described horizontal, vertical rib fill the full die cavity unit be made up of punch forming dynamic model and the quiet mould of punch forming; Step 5, when after a grid machine-shaping to be processed, forwards a processing length distance, repeats step one to step 4, until complete processing to all grids to be processed to a rear grid to be processed.
The present invention is by the one time punching molded processing and manufacturing completed grid, improve mechanical strength and the hardness of punching grid, working (machining) efficiency is improve while reducing material consumption, make punching and extrusion modling two techniques can together with carry out, this method has the advantage of technique such as continuous casting continuous rolling grid and punching grid etc., turn avoid the shortcoming of above-mentioned grid simultaneously.About 3 times that the corrosion resistant ability of grid adopting present invention process to make is the shaping grid of gravity casting, lead plaster adhesion property is gravity grid casting about 2 times.In addition, more save the consumption of lead material when grid is produced, improve production efficiency, reduce production cost, decrease the pollution to environment simultaneously.
