How does the conventional universal tensile testing machine work?
Source:wbe  Popularity:12  Time:2019-06-10

The process of pulling, pressing, bending and shearing between the fixed beam and the fixed beam is completed by moving the beam. Collect the force value data of the sensor and collect the displacement and deformation data of the encoder or the scale or the applicator. Test results relating to tensile strength, compressive strength, bending, shear strength, etc. of the test are calculated by hand calculation or computer.

 

The electronic universal motor drives the lead screw to rotate, so that the moving beam moves;

 

The hydraulic universal is pressurized by the oil pump to form a cylinder lift, which moves the moving beam.

 

The electronic equipment has higher precision, the operation is particularly simple, and the working environment is relatively clean. Suitable for small force test;

 

The hydraulic equipment has high precision. Because of the different density of oil used in the season, the working environment is relatively dusty, and it is suitable for the large value test.

 

First, the electronic universal tensile testing machine

Digital display

 

The test process is controlled by buttons on the device, the digital LCD screen displays the test results, and the test data such as tensile strength, compressive strength, specimen elongation and elongation are manually calculated, and a micro-printer can be added to print a simple test report. .

 

Microcomputer control

 

The whole test process can be controlled by the microcomputer, and the digital LCD screen and the computer can display the test results synchronously (in the event of a computer failure, the digital part can work independently to complete the test process), and the computer automatically analyzes and calculates the tensile strength, compressive strength and elongation of the test piece. , the final data required for the test, such as elongation, print the test analysis report of the regular format A4 paper. All test data can be stored and called at any time. The software backs up all data to prevent data loss after a computer failure recovery.

Second, hydraulic universal tensile testing machine

 

Digital display

 

Through the button on the device and the return valve to control the test process, the digital LCD screen displays the test results, and manually calculates the test data such as tensile strength, compressive strength, specimen elongation and elongation, and can add a micro printer. Print a simple test report.

 

Screen display

 

Through the button on the device and the return valve to control the test process, the digital LCD screen and the computer display the test results synchronously (in the event of a computer failure, the digital part can work independently to complete the test process), the computer automatically analyzes and calculates the tensile strength of the test piece. The final data required for the test of compressive strength and elongation, elongation, etc., print the test analysis report of the regular format A4 paper. All test data can be stored and called at any time. The software backs up all data to prevent data loss after a computer failure recovery.

 

Microcomputer control (also called electro-hydraulic servo or microcomputer servo)

 

The proportional valve or servo valve is used to control the whole test process through the microcomputer. The digital LCD screen and the computer display the test results synchronously (in the event of a computer failure, the digital part can work independently to complete the test process), and the computer automatically analyzes and calculates the tensile strength of the test piece. The final data required for the test of compressive strength and elongation, elongation, etc., print the test analysis report of the regular format A4 paper. All test data can be stored and called at any time. The software backs up all data to prevent data loss after a computer failure recovery.

 

Note: The clamping method of the jaw or the jaw (test piece clamping part) can be divided into manual clamping and hydraulic clamping. Conventional manual clamping.

 

Applicable industry

 

Metal profiles, building profiles, casting castings, metal pipes, steel wire ropes, steel smelting (various round steel, rebar) safety protection appliances.
