Plate material processing machine with bending function and tool for the same

Abstract

The present invention provides a plate material processing machine with a bending function which enables even a bending piece with two or more bending portions to be bent and which enables materials to be bend so as to have different bending directions, dimensions, angles, or the like using the same tools. An upper tool 21 and a lower tool 22 are provided which fix a plate material W by sandwiching it between themselves. An upper tool-side bending tool 23 and a lower tool-side bending tool 24 are provided on sides of the upper tool 21 and lower tool 22 , respectively, so as to elevate and lower freely. The upper tool-side bending tool 23 and the lower tool-side bending tool 24 perform elevating and lowering operations relative to the upper tool 21 and the lower tool 22 to bend a plate material piece Wa of a plate material W sandwiched between the upper tool 21 and the lower tool 22 . A plate material feeding mechanism adjusts the length over which the plate material piece Wa projects from the upper tool 21 and lower tool 22.

       4 . A tool used to bend a plate material, the tool being characterized by having a pivoting support point portion arranged at one end and pivotally supporting the entire bending tool, a bending edge arranged at the other end and pushed against the plate material, and guide projections arranged on one and the other sides of the bending tool, respectively, in a pivoting direction around said pivoting support point portion, wherein each of said guide projections contacts with means for regulating the pivoting angle of the bending tool.
