Abstract
The invention discloses a rapid detection method of a storage battery plate grid rib inner hole. The rapid detection method comprises the following steps of firstly, fixing a frame at the periphery of a plate grid; secondly uniformly applying pressure on each compartment rib of the plate grid to change the shapes of ribs by using the extensibility of lead; and judging whether holes exist and judging the positions of the holes according to the cracking conditions of ribs by considering the fact that due to the hole characteristics, the plate ribs are poor in rib strength at the holes and can crack under the stress state. The detection method provided by the invention has the advantages that the detecting efficiency is high, wrong detection and leaking detection conditions do not exist, in addition, the corresponding position of a mould of the plate grid is adjusted according to the detected hole position, and further the generation of a rib hole and an inner hole in the casting plate grid is avoided.
Description
Technical field
The present invention relates to Lead-acid Battery Technology field, be specifically related to the detection method of grid rib inner air vent.
Background technology
Pore on storage battery plants gate rib, particularly inner air vent be difficult to find in casting process, and pore easily causes rib to rupture in battery use procedure, and electric current can not conduct and affect serviceable life of battery.
The detection method of grid rib pore adopts visual examination more at present, and visual examination exists following defect:
1, the part that general pore is exposed is very little, and naked eyes are difficult to check out.
2, inner air vent occurs in rib inside, by visual examination, can detect out.
3, conventional detection method detection efficiency is low, easily has false retrieval, undetected situation.
Summary of the invention
Technical matters to be solved by this invention is just to provide a kind of method for quick of grid rib inner air vent, effectively finds grid rib inner air vent, improves detection efficiency and accuracy rate.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of method for quick of storage battery plants gate rib inner air vent, first, the frame of grid surrounding is fixed; Secondly, each little lattice rib of grid is evenly exerted pressure, utilize plumbous ductility, applied pressure causes the shape of rib to change; Finally, according to the characteristic of grid rib pore, leachy place, rib intensity difference can rupture stressed in the situation that, according to the situation of rib fracture, judges whether the position that pore exists and pore exists.
Preferably, according to the position that detects pore generation, on plate grid die, corresponding position is adjusted, avoided pore, inner air vent to occur.
Preferably, the degree of rib alteration of form according to different ribs meticulous and slab lattice thickness confirm.
Preferably, after grid rib stress deformation, rib peak is given prominence to frame 0.5-10mm.
The present invention is by applying certain pressure to the rib of whole each the little lattice of grid, according to rib crack conditions, judge whether pore, inner air vent exist and location, because each little lattice rib of every grid all detects, detection efficiency is high, does not have false retrieval, undetected situation.In addition, according to the position that detects pore generation, corresponding position is adjusted the generation of rib pore, inner air vent while further having avoided casting grid on plate grid die.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is the structural representation of each little lattice rib of grid while evenly exerting pressure state;
Fig. 2 is that grid is after each little lattice rib is evenly exerted pressure after Facad structure schematic diagram;
Fig. 3 is the A-A cross-sectional view in Fig. 2.
Embodiment
As shown in Figure 1 to Figure 3, a kind of method for quick of storage battery plants gate rib inner air vent, first, the frame of grid surrounding 1 is fixing; Secondly, each little lattice rib 2 of grid is evenly exerted pressure, utilize plumbous ductility, applied pressure causes the shape of rib to change; Finally, according to the characteristic of grid rib pore, leachy place, rib intensity difference can rupture stressed in the situation that, according to the situation of rib fracture, judges whether the position that pore exists and pore exists.
According to the position that detects pore generation, on plate grid die, corresponding position is adjusted, avoid pore, inner air vent to occur.
The degree of rib alteration of form according to different ribs meticulous and slab lattice thickness confirm, after grid rib stress deformation, the outstanding frame 0.5-10mm of rib peak 3.
