1、Introduction:

The EZ-10 wire torsion testing machine is mainly used for testing the number of unidirectional and bidirectional twists of metal wires. Suitable for fields such as steel metallurgy, construction and building materials, aerospace, quality supervision, and teaching and research institutions.

The testing machine is manufactured in accordance with relevant standards such as GB/T239.1-2012 Metal Material Wire Part 1: Unidirectional Torsion Test Method, GB/T239.2-2012 Metal Material Wire Part 2: Bidirectional Torsion Test Method, GB/T5224-2003 Steel Wire for Prestressed Concrete, etc.

II Scheme description:

2.1 Host:

The host adopts a horizontal structure, with a servo motor as the power system, and applies different pre tightening forces using weights and lever principles.

2.2 Control System:

2.2.1 Two different testing methods can be selected: a unidirectional torsion test; Bi directional torsion test;

2.2.2 Different sample speeds of 0.5r/s-2r/s can be selected according to different samples for adjustment

2.2.3 Parameter settings can be set to stop the test with a specified number of turns, or the test can be stopped by directly twisting and recording the number of rotations.

3、 Main technical performance indicators:

1. Twist diameter range: φ 0.1- φ 10mm

2. Collet spacing: 0-550mm

3. Coaxiality of two clamping heads: ＜ φ 0.4mm

4. Parallelism of mobile guide rail: ＜ 0.2mm

5. Rotation speed: 0.5r/s-2r/s can be adjusted freely

6. Clamping method: manual

7. Clamping jaws: 0.1-2.5, 2.5-5, 5-10 (hardness ≥ 55HRC)

8. Weight of weights: 10N * 1, 20N * 2, 50N * 1, 100N * 1 (weight accuracy ± 1%)

9. Working voltage: AC 380V ± 10% 50Hz
