Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

The horizontal automatic 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. It is an ideal testing equipment for industrial and mining enterprises, technical supervision, commodity inspection and arbitration, scientific research institutes, tertiary institutions, quality inspection units and other departments.

"JB/T 9370-1999", "JJG 269-2006" torsion test machine standard

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.

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.

3 functional characteristics

3.1 real time display torque, peak, twist angle

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.

3.3 the control method is simple, which is suitable for precise measurement in the laboratory, and also suitable for batch inspection of the production line.

3.4 electronic handwheel control, multi gear speed control, manual running time 10 files, automatic running speed.

3.5 10 test points can be set up at most, and the torsion stiffness can be shown by the test results.

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

3.7 automatic preset torque can be achieved, the torsion angle can be automatically cleared, and the test will automatically return to the initial state.

3., the first large LCD screen in 8 countries can synchronously display the torque and torsion angle curves, which can directly reverse the mechanical properties of the spring.

3.9 has sensor overload protection: in order to protect the safety of sensors and mechanical components, when the torque reaches the set maximum torque 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.

3.10 maximum storage of 50 sets of data, torque, twist angle, stiffness and other data printing.
