Wire bending testing machine

The machine is designed to test the wire of ferrous and non-ferrous metals and their alloys for inflection according to GOST 1579.

The principle of operation of the machine is based on the fact that one end of the sample is clamped between the jaws of the vice and bent to the right and left by 90° until it breaks or until the number of swings that meets the technical specifications for metal products is reached. The number of bends that the specimen has withstood characterizes its quality.

It consists of the following main nodes:

  • lever drive,
  • carriages,
  • damper,
  • vise,
  • control panel,
  • fencing.

All nodes are mounted on a common plate.

Execution - desktop.
