Abstract

The invention relates to the field of metal materials, and in particular discloses a metal plate bending device. The metal plate bending device comprises at least one detection component; each detection component comprises a pressure head (50) and a pair of supporting seat monomers (40); each supporting seat monomer (40) is provided with a fixed part (41) fixed to a testing machine or a press machine; each supporting seat monomer is provided with opposite side surfaces; the tops of the opposite side surfaces are provided with inclined surface parts which are upwards inclined close to each other; when the metal plate bending device is used for performing a bending performance test, the paired supporting seat monomers are symmetrically fixed to the testing machine or the press machine; the pressure head comprises a conical head part; the cone angle of the conical head corresponds to the included angle between the inclined surface parts of the paired supporting seat monomers. According to the metal plate bending device provided by the invention, calculation is not involved when the bending performance of a metal plate is tested, and the bending angle of the metal plate to be tested can be determined intuitively and effectively.

Description

technical field [0001] The invention relates to the field of metal plates, in particular to a metal plate bending device used for testing the bending performance of metal plates. Background technique [0002] Sheet metal needs to meet certain bending properties to be considered qualified. In "GB / T3621-2007 Titanium and Titanium Alloy Plates", corresponding to different grades of titanium and titanium alloy plates, there are 30°, 35°, 40°, 50°, 60°, 70°, 80°, 100°, 105°, 120°, 180° different bending angle requirements. When performing the bending performance test of the metal sheet, use the bending device to bend the inspected metal sheet to a specified angle. When the inspected metal sheet is bent to the specified angle, it is qualified if there is no visible crack on the outer surface of the inspected metal sheet. In this detection process, the determination of the bending angle is an important issue. [0003] In Appendix B of GB / T232-2010, the "method for determining th...
