Corkscrew Pull Out Tester

Main functions of the equipment:

TN5005 tensile torque testing machine adopts column frame structure, tensile pressure and torque are tested in the frame at the same time, the two channels are used separately, tensile pressure is loaded by servo electric lead screw, torsion is loaded by servo motor reducer and dynamic torque sensor, tensile torque testing machine is mainly used for non-metallic materials, small force value structural parts, rubber bottle stopper, and so on. The system can also be operated in a single axis, and the corresponding tensile or torsion experiments can be carried out.

The whole structure adopts column type frame structure, which is composed of column, sliding table, middle moving cross beam, tensile pressure loading, torsion loading, and upper connecting auxiliary top beam.

The tension and torsion experiment can be tested separately or simultaneously, and the two can not be coupled in the experiment.

The space adjustment is adjusted by the lead screw of the drawing end, and the electric control is easy to operate.

The cross beam movement and emergency stop operation buttons are placed next to the main engine, which are convenient for the tester to operate;

The equipment adopts unitized, standardized and modular design, which has the characteristics of low damping, high response, high life and no gap design.

2. Testing machine (system) control software Supertest3.0:

2.1 System management software simttest3.0: This software is the basis of the whole digital servo controller work, its main functions are to manage the hardware resources of the control system, define sensors, adjust digital control parameters, set protection, display the current control mode and function generator status and sensor calibration.

2.2 Multi-functional test software Supertest3.0: This software is a flexible, full-function test software, users can use it to design special test methods, but do not need programming. This software has a variety of control functions, data acquisition functions and other auxiliary functions of the servo controller are done on a panel in the form of ICONS, users can drag and drop these function ICONS into the test definition panel with the mouse, and combine them according to user needs at will, you can test according to user-defined test methods. The software can be used for random spectrum (a combination of different experimental processes) tests.

2.3 Control System
