Title:
SHEET MATERIAL CUTTING DEVICE
Document Type and Number:
Japanese Patent JP3039389
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To adjust the clearance for two sides of the edge formed in L shape by one adjust operation simultaneously and constitute the elevating mechanism of a movable edge simply.
SOLUTION: This device is provided with a fixed edge 13 with a nearly L shape in plane form and an elevatingly movable edge 12 formed in nearly L shape along this fixed edge 13. The movable edge 12 is installed on the tip of a ram 15 turned vertically through turning support shaft 14 installed on a lower frame 11. The swing center of the ram 15 is changed by making the turning support shaft 14 to an off-centered shaft and adjusting a rotational angle and the clearance between edges 12, 13 can be adjusted. The axial direction of the turning support shaft 14 is made in a slant direction for either one of both sides formed in L shape of the fixed edge 13 and thereby, the clearances of both sides formed in L shape of the edges 12, 13 can be adjusted simultaneously by only the adjustment of the rotational angle of the turning supporting shaft 14.
