Cement electric bending machine using the method

Cement electric bending machine using the method:

1, keep the lever balance, in use should always pay attention to checkwhether the loosening lever balance, balance and fasteners.

2, check whether the upper and lower clamp in a central line, the supportcylinder is clean, wear, rotating freedom under the fixture whetherfreedom of movement.

In 3, will try to block into the flexural fixture according to put cement baffle,and the adjustment fixture to leverage a specimen is broken in the nearequilibrium elevation.

4, test: according to the above points after the check card test block can begin to test, according to drive the screw rod to rotate poise from "0" to start moving loading motor start button, when added to a certain value of specimen broken, one end of the main ruler is positioning contact rodpressure switch motor microcomputer around thallium stop stop, this timenote values, completed a test process.

The bending strength is calculated according to the following formula:

Rf=3Pe/2bh2=0.234P

Where: Rf -- flexural strength of kg/cm2

P -- load kg

E -- the support cylinder center distance 10cm

B, h -- the specimen section width and height were 4cm

The test can be directly read flexural strength values from the standardsize, MPa.
