Metal wire bending testing machine

Abstract

The invention relates to a metal wire bending testing machine, which comprises a base, one side of the top side of the base is fixedly connected with the lower end of a stand column, a swing mechanismis fixedly installed at the upper end of the stand column, and the right end of an output shaft of the swing mechanism is fixedly connected with the middle of the left side of a swing plate; two shifting rods in front-back symmetry are mounted at the lower end of the right side of the swing plate, and a coaxial first bevel gear is fixedly mounted on the right side of the periphery of an output shaft of the swing mechanism. The metal wire bending testing machine is simple in structure and ingenious in conception, a metal wire fixing device can rotate along with swinging of the metal wire, andtherefore the axis of the metal wire close to the metal wire fixing device and the axis of a wiring hole of the metal wire fixing device are kept collinear, and bending of the metal wire close to themetal wire fixing device is reduced; the problem that the position, close to the metal wire fixing device, of the metal wire is broken more easily, and accuracy of a metal wire bending test is affected is solved, market requirements can be met, and popularization is facilitated.

Description

technical field [0001] The invention belongs to the field of metal wire testing devices, in particular to a metal wire bending tester. Background technique [0002] In the metal products industry, the toughness index of the steel wire is characterized by repeatedly bending the steel wire by a bending tester and recording the number of times the steel wire is bent before breaking. Generally, the greater the number of bending times, the better the toughness of the steel wire. However, during the bending process of the wire, due to the constant change of the angle between the wire fixing device and the wire, the wire is more likely to break near the wire fixing device, thus affecting the accuracy of the wire bending test , can not meet the actual needs, so we invented a wire bending test machine. Contents of the invention [0003] The invention provides a metal wire bending tester to solve the defects in the prior art. [0004] The present invention is achieved through the ...
