Semi-automatic cutting sampling instrument for lead-acid storage battery separator
Technical field
The present invention relates to lead-acid accumulator, be specifically related to lead-acid accumulator microporous polyethylene dividing plate semi-automatic cutting sampling instrument.
Background technology
According to the requirement of JB/T7630.5-2008 lead-acid accumulator microporous polyethylene dividing plate, the mensuration of its cross growth rate need to be made specific sample (such as Fig. 4).Materialsed all is to adopt manual cutting in the past, does not reach the precision of demand, and the result that impact detects does not have this sampler in the market, and the present invention can satisfy the sampling precision requirement of sample, and easy to operate.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of semi-automatic cutting sampling instrument for lead-acid storage battery separator, and sampling precision is high, and is convenient to operation.
The present invention is achieved through the following technical solutions:
Semi-automatic cutting sampling instrument for lead-acid storage battery separator, the shaping pressing plate that comprises die and die shoe thereof, upper bolster and be positioned at the upper bolster bottom, described upper bolster and shaping pressing plate are movably connected on die by the set guide pillar of die;
Also comprise the punch with the die cavity of die coupling, described punch pass upper bolster, shaping pressing plate and with its flexible connection, the punch upper end is provided with the punch push pedal, is connected with the cylinder bar of cylinder above the punch push pedal;
Described punch push pedal is movably connected on upper bolster, set spacing guide pillar, the spacing guide pillar a of shaping pressing plate difference, is respectively equipped with back-moving spring, back-moving spring a on described spacing guide pillar, the spacing guide pillar a.
The further improvement project of the present invention is, described cylinder is arranged on the fixed head, and the two ends of fixed head are fixed on the support bar of upper bolster, and fixed head is provided with the guide pillar hole, and the guide pillar set with the punch push pedal is flexibly connected.
The present invention compared with prior art has the following advantages.
The present invention is simple in structure, is convenient to make processing, and is cheap.
The present invention is under the effect of cylinder, and exemplar is easy to make fast, precision is high.

Embodiment
As shown in Figure 1, 2, 3, the shaping pressing plate 4 that the present invention includes die 3 and die shoe 1 thereof, upper bolster 5 and be positioned at upper bolster 5 bottoms, described upper bolster 5 and shaping pressing plate 4 are movably connected on die 3 by die 3 set guide pillars 2.
Also comprise the punch 6 with the die cavity of die 3 coupling, described punch 6 pass upper bolster 5, shaping pressing plate 4 and with its flexible connection, punch 6 upper ends are provided with punch push pedal 7, are connected with the cylinder bar of cylinder 9 above the punch push pedal 7.
Described punch push pedal 7 is movably connected on upper bolster 5, set spacing guide pillar 12, the spacing guide pillar 12a of shaping pressing plate 4 difference, is respectively equipped with back-moving spring 13, back-moving spring 13a on described spacing guide pillar 12, the spacing guide pillar 12a.
Described cylinder 9 is arranged on the fixed head 11, and the two ends of fixed head 11 are fixed on the support bar of upper bolster 5, and fixed head 11 is provided with the guide pillar hole, and the guide pillar 8 set with punch push pedal 7 is flexibly connected.Fixed head 11 is provided with the reversal valve 10 of cylinder 9.
As shown in Figure 2, a side of die 3 is provided with two locating pieces 14.The below of die 3 is provided with stock guide 15.
The course of work of the present invention: at first dividing plate is sent into (by locating piece 14 location) between die 3 and the punch 6, reversing valve operated 10, cylinder 9 promotes punch push pedal 7 to pressing down, punch push pedal 7 descends and promotes upper bolster 5 and shaping pressing plate 4 to die 3 displacements by being arranged on back-moving spring 13, back-moving spring 13a on spacing guide pillar 12, the spacing guide pillar 12a along spacing guide pillar 12, spacing guide pillar 12a, when shaping pressing plate 4 flattens dividing plate, punch 6 presses down the dividing plate cutting, and the dividing plate after the cutting flows out along stock guide 15.After cutting finished, reverse operation reversal valve 10, cylinder drove punch push pedal 7, drive upper bolster 5, shaping pressing plate 4 resetted when punch 6 resetted.
