Overview

The XWW-20 digital electronic universal material testing machine is mainly used to test the tensile and compressive properties of various materials and the ring stiffness of plastic pipe fittings. In tensile testing, technical indicators such as maximum bearing tensile strength, tensile strength, elongation deformation, and elongation rate of the material are tested; In compression testing, technical indicators such as bearing pressure, tensile strength, and maximum compression deformation of the material are tested.

Digital display electronic universal material testing machine

The structural characteristics and working principle of the testing machine

This machine consists of two main parts: mechanical and electrical

4.1 Mechanical structure and working principle:

This machine adopts electric loading method, and the bottom is the structural support bracket of the whole machine, which contains components such as motor driver, loading motor, reduction system, power transmission mechanism, etc;

The upper part is the specimen clamping and force value, deformation measurement mechanism, which includes the main components such as loading transmission mechanism, specimen stretching fixture, specimen compression fixture, force sensor, displacement sensor, etc.

4.2 Electrical part:

The electrical part consists of a display measurement control part. The display measurement control part realizes various functions such as control, display, data acquisition, and processing. The main controller can select tensile, stiffness, and compression test modes according to different test requirements, and set the sample parameters for each test mode. After adjusting the sample, press the test button, and the system will automatically start the test. Based on the corresponding test conditions, the system will automatically determine the shutdown process and display the corresponding test results.

4.3 The main functions of this machine are:

4.3.1 Fully Open Parameter Settings

4.3.2 Set parameter saving, automatically read and display on the next startup

4.3.3 Floating zero point setting, adjustable zero point at any time

4.3.4 Peak retention and storage, constant value following;

4.3.5 Within the effective speed range, the speed value can be set arbitrarily;

4.3.6 Quick speed switching function during the movement of the crossbeam

4.3.7 Flexible data query and display function;

4.3.8 Overload shutdown and audio alarm protection function;

4.3.9 Automatic judgment function at the end of the experiment;

4.3.10 Extreme position protection, etc;

Digital display electronic universal material testing machine

The ARM801 testing machine controller consists of a main control board, keyboard, and display driver board, as shown in the following figure. The main control board collects force and displacement signals, drives the motor to move according to the test procedures, and obtains the required results. The main control board uses an ARM series 32-bit processor, which is powerful and fast in operation. The following will provide specific instructions based on the signal wiring

The main control board is connected to both the keyboard and the display driver board to receive keyboard commands and output display information. The keyboard can be a keypad or a membrane keyboard

LCD displays can display test curves and multiple test results in real time, and can be connected to various models of needle printers or thermal micro printers to print test curves and results. There are many types of driving motors, such as DC speed controllers, stepper motors, servo motors, frequency converters, proportional valves, etc. It can be used in both harsh environments in factory production workshops and clean environments in laboratories, with fast and flexible operation.
