Described punch comprises cuboid block-shaped body and is located at the blade of body lower part, blade is can the strip structure of horizontal set sealing strip, top, cuboid block-shaped body another side is provided with horizontal fixed block, the through hole that sectional dimension is identical with punch sectional dimension is provided with in the middle part of described punch retainer, punch is arranged through this through hole, punch upper surface is also provided with the holding tank for holding horizontal fixed block, described punch retainer is fixed by means of hexagon socket head cap screw and upper bolster.
Described die shoe lower surface fixedly mounts the second cushion block.
Described upper bolster is provided with the positioning through hole for wearing guide pin bushing, and positioning through hole upper end is fixedly installed the first cushion block, and described guide pin bushing wears from positioning through hole lower end, is provided with spacing ring in the middle part of described guide pin bushing.
Described sealing strip comprises U-shaped hard PVC matrix, be located at the stainless steel band in hard PVC matrix and the Liang Taoshui be located on hard PVC matrix right flank cuts portion, and water is cut on lower surface and planted nylon hair.
The beneficial effect adopting technique scheme to produce is: by being arranged to the blade of punch can clamp the strip structure of sealing strip, in blanking process, according to the blade of cutting position, shape and length requirement design punch, and coordinate with die, only the single side be positioned at below blade is excised, greatly enhance productivity, and only need clamped one time can complete many places excision, error is less, improves product quality.
