产品简介

The horizontal spring torsion tester is suitable for testing the torsion angle and torsional moment of all kinds of large springs. Additional accessories can also be used for torsion tests of components and components. Horizontal manual spring torsion tester is in line with JB/T 9370-1999 and JJG 269-2006 torsion testing machine standard and material test method. According to national standards and ISO, JIS, ASTM, DIN and other international standards to test and provide data, is the industrial and mining enterprises, technical supervision, commodity inspection arbitration, scientific research institutes, colleges and universities, quality inspection units and other departments of the ideal testing equipment.

执行标准

JB/T7796—1995

功能特点

1.1 mechanical structure

The model is vertical structure, and the base is made up of two thickened steel plates. The structure is stable and firm, and the beam is driven by the screw driver to facilitate the adjustment of test space. The power adopts the precision stepping motor, the turbine worm reducer, the torque output is stable, and has the characteristics of fast response and high control accuracy.

1.2 control system

The control unit of this machine is the micro operating system developed by our company. It uses the American import Atmel microprocessor as the main control chip. The analog to digital conversion chip is the AD chip produced by the international well-known IC manufacturer ADI. With the mature control mode of our company, the stability and precision of the whole machine are in the leading level in the industry. The screen is made of industrial LCD screen, which has the characteristics of long life, stable performance and wide viewing angle.

1.3 functional characteristics

Real-time display of torque, peak value and twist angle in 1.3.1

1.3.2 has a peak hold: the test torque increases from 0. The system acquiescence starts with a new experiment, and automatically records the peak value of the test.

The 1.3.3 control method is simple, suitable for precise laboratory measurement, and also suitable for batch inspection of production lines.

1.3.4 electronic handwheel control, multi gear speed control, manual running time 10 files, automatic running arbitrary speed;

1.3.5 can set up 10 test points at most. The test results can show torsional stiffness.

1.3.6 can realize 2 functions of torque measurement, torsion angle and torque measurement.

1.3.7 automatic mode can realize preset pretightening torque, automatic twist zeroing, and test automatically return to the initial state.

1.3., the first big LCD screen in the country has synchronous display of torque and torsion curve, which can directly reverse the mechanical properties of the spring.

1.3.9 has sensor overload protection: to protect the safety of sensors and mechanical components, when the torque reaches the set torque upper limit, the alarm is called, if the system is running at this time, the system will automatically run in the opposite direction until the torque is stopped in the normal range.

1.3.10 can store 50 sets of data, and print data such as torque, twist angle and stiffness.
