Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the drawings and the specific embodiments.
The utility model discloses a be used for preparing fuel cell metal polar plate side cut waste material separating mechanism, as shown in figure 1, it is different from prior art and lies in: separating mechanism includes base 1, slider 2, connecting rod 3, cylinder 4, base 1 surface forms the domatic 5 of slant distribution, domatic 5 department forms spout 6, slider 2's lower part form with the reverse domatic 7 of the domatic 5 complex of above-mentioned, reverse domatic 7 department forms with spout 6 complex spout piece 8, slider 2 upper surface is the level form and distributes, slider 2 upper surface department vertically is provided with locating pin 9, the one end and the 2 swing joint of slider of connecting rod 3, the other end and the output of cylinder 4 of connecting rod 3 are connected, cylinder 4 is fixed on fixing base 10.
When the device is specifically implemented, one end of the connecting rod 3 forms a cylindrical or spherical end part, the side wall of the sliding block 2 is provided with an assembly groove 11 matched with one end of the connecting rod 3 in shape, the cross section of the groove body of the assembly groove 11 is approximately a circular groove, and the cross section of the circular groove body is smaller than a whole circle and larger than a semicircle.
In specific implementation, the cross section of the groove body of the sliding groove 6 is approximately a circular groove, the cross section of the circular groove body is smaller than a full circle and larger than a semicircle, and the cross section of the sliding groove block 8 is matched with the cross section of the groove body of the sliding groove 6.
As shown in fig. 2-3, the trimming scrap separating structure is applied to a conventional fuel cell metal unipolar plate trimming and punching composite die, the structure of the traditional fuel cell metal unipolar plate trimming and punching composite die is not changed, the fuel cell metal unipolar plate trimming and waste material separating structure is applied to the traditional structure, the die has simple mechanism, convenient processing and assembly, high size precision after blanking, the upper die part mainly comprises a trimming female die, a punching male die and an inner stripper plate, after blanking, the metal unipolar plate can be detained in the die cavity of side cut die, and interior stripper plate is ejecting with the metal unipolar plate under the effect of spring, and lower mould part mainly cuts edge and punches a hole punch-die template, takes off the board outward, and the metal unipolar plate waste material that punches a hole discharges the mould through the inside waste material hole of mould, and the metal unipolar plate is cut edge the waste material and is ejected lower mould punch-die template under the effect of taking off the board outward.
