Rookie novices should first understand their performance and operating steps in detail

The multifunctional tensile machine adopts the design of electromechanical integration, which is mainly composed of load cell, transmitter, microprocessor, load drive mechanism, computer and color inkjet printer. High-precision electronic speed-regulating motor can set stepless test speed. All integrated components are connected by plug connection. Floor-mounted models, modeling and painting have fully considered the relevant principles of modern industrial design and ergonomics. If you are a novice, you must first understand the principles, functions and operating steps of this machine in detail.

This machine is a gantry type rack with a novel and elegant appearance. Computer digital speed control system, equipped with force sensor and elongation automatic tracking device, with good stability. The electrical appliance adopts a PC and an interface circuit board to collect, store, process and print the test results. It can calculate the basic physical performance parameters of some materials such as vigorous force, yield force, average peel force, and large deformation. During the test, the computer collects force values ​​and deformation signals in real time, and the software displays the "force value-displacement" curve. After the test, the parameters are automatically calculated and saved, and the bottom report form required by the user can be printed out.

1. Structural principle:

The host consists of electronic speed control system, transmission mechanism, force measurement system and elongation automatic tracking device.

Electronic speed regulation system: The machine adopts AC speed regulation, the corresponding stretching speed is 1-Xmm / min (X is the user's bottom requirement), and returns at the highest speed.

Transmission mechanism: The belt reduction motor drives the screw drive through a synchronous belt and a pulley.

Force measuring system: The load cell is installed on the moving beam of the host (the sensor is only subjected to vertical force, not torsional force and direction measuring force) to ensure accurate force measurement. During the test, the force of the sample can be changed from the sensor to an electrical signal input.

Elongation tracking device: This device is used to measure the deformation of the sample, and can be tracked by the tracking device and the deformation device built in the motor.

Second, its software function introduction:

A. Load displacement curve; load, time curve; displacement, time curve; stress, strain curve.

B. Edit the corresponding test standards according to the requirements of each country on the test piece, fill in the test data, edit the test method, and be available for future test selection.

C. Automatically store the test results, and edit them as report printouts. With formula editing function, you can compare multiple tested curves.

D. Can set the number of decimal places, each physical quantity unit and password protection.

3. Basic operation steps:

Power on → Select test item → Set test parameters → Start test standby state → Clamp test piece → Start test → Automatic return to the end of test → Send test data → Display test result and curve → Test result * storage → Output test result as required With curve

The multifunctional tensile machine can display the test process and curve through the computer display, and the microcomputer can automatically transmit the test settings and test data. Users can modify the test report according to their requirements and output standard reports. Through the superposition analysis of the group test curves, the quality control parameters can be accurately grasped. The multi-mode data query function enables managers to clearly grasp the development trend of quality control. The specially designed software function can enable the experimenter to quantitatively grasp the state parameters of the key points in the application process of the test material, and accurately carry out process adjustment and production control.
