After the clamping mechanism 307 unloads the prepreg, the blanking mechanism 1 starts to operate, the blanking cylinder 104 operates to push the punching knife group mounting plate 103, so that the knife group mounting plate 103 moves downwards, and the knife group mounting plate 103 drives the cutting knife group 106 to vertically downwards cut under the guiding action of the blanking optical axis 105.
Punching mechanism 1 carries out the punching press through blanking cylinder 104 and knife tackle mounting panel 103, tailorring knife tackle 106 self weight, and power has 30000N approximately, guarantees to decide prepreg to can once only tailor the shaping, it is higher than the accuracy of tailorring alone, can not form too much cut opening, feed mechanism 3 and punching mechanism 1 can move simultaneously moreover, do not influence each other, improve and tailor efficiency.
