Abstract

PURPOSE: To bend plate material to various shapes and also reduce spring back of the bent material, by sliding several inside and outside bending machines reciprocatingly along the guide rail of the base.
CONSTITUTION: One pair of the inside bending machines 14, 15 and the outside bending machines 16, 17 are arranged along the guide rails 12, 13 of the base 11. The dies 23, 24 of the inside bending machines 14, 15 decide the bending angle of the frame material 140, and clamp the frame material 140 with the keep plates 21, 22 by operating the air cylinders 29, 30. The bending boards 25, 26 connected to the keep plates 21, 22 are operated by the cylinders 31, 32, and are bent along the dies 23, 24. The outside bending machines 16, 17 are operated in the same way. In case this bending device 10 is moved on the guide rails 12, 13 of the base 11, material can be bent in various dimensions, and irregularities of bending work can be reduced.
