Testing Machine

product description

Product introduction

The spring tension and compression testing machine is made according to the technical requirements specified in the JB / T 7796-1995 spring tension and compression testing machine standard. It mainly performs tensile and compression tests on various coil springs. The test force of the spring is measured under a certain displacement, or the deformation of the spring is measured under a certain test force. It can also be used for other elastic components and small mechanical performance tests. It is mainly used in spring manufacturers, low-voltage electrical plants, and power machinery Factories, colleges and universities and scientific research units.

Product composition system

1. Host: adopts door-type frame structure.

2. Transmission system: It consists of reducer, precision screw pair and guide part.

3. Drive system: The system is driven by the AC servo governor and the motor.

4. Measurement and control system: The test force measurement and control system is composed of high-precision load sensors, measurement amplifiers, A / D converters, and regulated power supplies; the displacement measurement and control system is composed of photoelectric encoders, frequency doubling shaping circuits, and counting circuits. Through various signal processing, functions such as computer display, control and data processing are realized.

5. Safety protection device: model break stop, overload protection, beam limit position protection, over current, over voltage, over speed protection, etc.
