Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1 to 4, an automatic bending machine rear baffle positioning device comprises an upper knife edge 1 which moves up and down by a power spindle drive, a lower knife edge 2 which is arranged right below the upper knife edge 1, a rear baffle 3 which is arranged at the rear side of the lower knife edge 2 and used for positioning a sheet metal part 5, a manipulator 4 which is arranged at the front side of the lower knife edge 2 and used for clamping the sheet metal part 5, a first sensor 6, a second sensor 7, a third sensor 9 and a control box 10, wherein the manipulator 4 clamps the sheet metal part 5 and pushes the sheet metal part 5 to the rear baffle 3 for positioning, the upper knife edge 1 is driven by the power spindle to move downwards to interact with the lower knife edge 2 to bend the sheet metal part 5, the rear baffle 3 has two rear baffles, the first sensor 6 is fixedly arranged at the front side of one rear baffle 3, the second sensor 7 is fixedly arranged at the front side of the other rear baffle 3, and a support 8 is arranged at the rear side, support 8 upwards extends along vertical direction, third sensor 9 is installed on the top of support 8, the signal output part of first sensor 6 the signal output part of second sensor 7 with the signal output part of third sensor 9 respectively with the signal input part electric connection of control box 10, first sensor 6 with second sensor 7 is located same horizontal plane, third sensor 9 is higher than first sensor 6 with the plane in second sensor 7 place, the signal output part of control box 10 respectively with the signal input part of manipulator 4 and the signal input part electric connection of power main shaft.
