Claims

[Claims for Utility Model Registration] Fixed bending device 5 fixedly arranged on the base 4
In a sheet material processing machine which is provided with a movable bending device 6 whose position can be adjusted freely toward and away from the fixed bending device 5, between both the fixed and movable bending devices 5 and 6, An intermediate support that supports from below the intermediate part of the workpiece W carried across the lower plate 12 of the double folding devices 5 and 6, and that moves on the base 4 so as to be able to move toward and away from the fixed folding device 5. 7, and large-diameter chain wheels 26, 28 and small-diameter chain wheels 2 are provided at both ends of the entire movement stroke for adjusting the position of the movable bending device 6, respectively.
5 and 27 are provided between both large diameter chain wheels and between both small diameter chain wheels.
9 and 30, and the chain 29, which is hung between large diameter chain wheels, is fixedly connected to the movable bending device 6 and rotates together with the movement of the bending device 6 toward and away from the movable bending device 6. At the same time, the chain 30 suspended between the small-diameter chain wheels is fixedly connected to the intermediate support 7, and the large-diameter chain wheel 26 and the small-diameter chain wheel 25 on either side of the two ends are connected so as to be integrally rotatable. ,
The number of gears in the small diameter chain wheels 25 and 27 is set to one half of the number of gears in the large diameter chain wheels 26 and 28.
A workpiece intermediate support device in a plate processing machine, characterized in that the device is set to. Both the fixed and movable bending devices 5 and 6 are provided with support frames 36 and 36 whose base ends are pivotally supported by the mutually opposing outer wall surfaces 11A and 11A and are forcibly swung up and down, and support frames 36 and 36 are provided at the free ends thereof, respectively. A workpiece intermediate support device in a plate material processing machine according to claim 1, further comprising workpiece support devices 38, 38 each having a receiving member 37, which is provided with a support member 37.
