1. Project introduction

        TPW series microcomputer-controlled spring fatigue testing machine is composed of driving system, transmission system, computer control display and other systems, and is suitable for fatigue performance testing of various coil springs. The test machine is controlled by an electromagnetic speed regulation system to control the operation of the motor. The eccentric device drives the connecting rod to raise and lower the reciprocating pressure plate to complete the reciprocating compression fatigue test of the spring. The machine is pollution-free, high in efficiency, has a wide frequency range and test space, and is equipped with suitable accessories to complete spring fatigue tests of different specifications. The machine is controlled by a single-chip microcomputer to realize the automatic shutdown function when the number of tests is reached. The machine has high integration, simple structure, low failure rate, stable and reliable performance, and simple operation. It is widely used in industries such as factories and mining enterprises, scientific research institutions, etc.

        This machine meets the standards:

         Technical conditions of JB/T9397-2002 tension and compression fatigue testing machine

        GB/T2611-1992 General technical requirements for testing machines

2. Program description

1. Host: mechanically loaded, using traditional crank-connecting rod mechanism, driven by electromagnetic speed-adjusting motor, using flywheel energy storage method to ensure uniform loading stability and operational reliability, so that the entire alternating stress forms a good sinusoidal waveform . Also equipped with spring pre-adjustment device (manual adjustment method), amplitude adjustment device (manual adjustment method), etc.

2. Transmission system: It is composed of speed increasing device, lead screw and guiding part.

3. Drive system: driven by electromagnetic speed regulating motor.

4. Measurement control system: It is composed of computer data acquisition and processing system, counter, speed controller device, force measurement system, etc., through various signal processing, realizes display, control and other functions and records the number of tests, test frequency, test force, etc. . And real-time display force-time curve and so on. Simple adjustment and stable performance.

5. Software operating system: adopt WinXP Chinese operating platform. The format of the test report can be output in Word or Excel format.

6. Safety protection device: automatic shutdown, over-current, over-voltage, over-speed protection device, etc. when the set number and time are reached.

7. Accessories: a set of universal fixtures.
