Abstract
A bending angle detecting device for a workpiece used in a bending machine that bends the workpiece in cooperation of upper and lower tools. The bending angle detecting device has a detector which includes a casing and which can detect a bending angle of the workpiece with the casing fixed in contact with a contact portion of the lower tool.
Claims6
A workpiece bending angle detecting device used in a bending machine which bends a workpiece in cooperation of upper and lower tools, the workpiece bending angle detecting device comprising:
- detector that detects a bending angle of the workpiece using at least one contact element of the detector that is moved to contact the workpiece as a casing of the detector disposed around the at least one contact element is fixed in contact with a contact portion of one of the upper and lower tools;
- a first moving unit which moves the detector between a position of the detector when the casing of the detector is fixed in contact with the contact portion and a position of the detector when the detector is separated from the tools;
- and
- a second moving unit which moves the detector in a direction of a bending line of the workpiece when the detector is separated from the tools by the first moving unit.

A workpiece bending machine, comprising:
- a bending sequence determination unit that determines a bending sequence of a workpiece on the basis of product information;
- a tool determination unit that determines tools used for bending of the workpiece on the basis of the product information;
- a tool layout determination unit that determines a layout of the tools used for bending of the workpiece on the basis of the product information;
- a workpiece position calculation unit that calculates, as workpiece position information, a position of the workpiece with respect to setting positions of the tools determined by the tool layout determination unit for each step of the bending sequence of the workpiece determined by the bending sequence determination unit;
- an angle detection position determination unit that determines a position where the bending angle of the workpiece is detected for each step of the bending sequence of the workpiece determined by the bending sequence determination unit;
- and
- a plurality of workpiece bending angle detecting devices which detect the bending angle of the workpiece and which are allowed to be independently moved and positioned,
- wherein the angle detecting position determination unit determines a number and positions of the workpiece bending angle detecting devices used on the basis of the product information, and
- wherein each of the workpiece bending angle detecting devices comprises a detector that detects a bending angle of the workpiece using at least one contact element of the detector that is moved to contact the workpiece as a casing of the detector disposed around the at least one contact element is fixed in contact with a contact portion of one of the upper and lower tools.
