It should be noted that the utility model is a kind of electronic type metal Rockwell apparatus, during work：
1. just test force debugging process：First test force is as caused by prefastening force spring, adjusts before product export and wherein applies
Two pretightning force adjusting nuts on power bar, so as to adjust the pretightning force of prefastening force spring, it is desirable to be：Force application rod upper end and connector
When 0.1mm or so gap is still arranged at bottom, elastic force 98.07N, so, when penetrator is arranged on force application rod bottom ram
Kong Zhong, pressure head press to sample, and when force application rod is risen to connector to 0.1mm gaps, the power that pressure head is pressed on sample is pre-
Clamp force, it is 98.07N.
2. device and sample installation process：The WD-5000E electronic universal testers of our factory production are taken, by electronics hardness
Meter connector be installed on the moving beam of testing machine, be plugged and mount pin, and use connector nut check, make device fixation not
It can swing；Suitable sample, which is installed, in lower contact on experiment machine platform lays base.Call through test electromechanical source, open electricity
Brain, computer are connected with electronics Durometer measurements device, by moving up and down crossbeam, adjustment suitable test space；Dress experiment is placed on
Sample is steadily laid and firmly on base, and decline moving beam just touches sample to pressure head sheath.
3. test process：Moving beam is moved down, and test is proceeded by sample.Now, electronics Durometer measurements device with
Crossbeam moves downward, and pressure head sheath is jacked up by specimen surface to contract, and pressure head, which stretches out, presses to specimen surface；Continue to push, pressure head meeting
Jacked up, promote and contracted on force application rod, when being reduced on force application rod with upper binding head 0.1mm without contacting connector, pretension bullet
The power that spring applies 98.07N is added on pressure head by force application rod, forms just test force；Kept for 2 seconds, then, within the 4-8 seconds, controlled
Row pushes crossbeam again, when the sensor force value on crossbeam reaches the force value needed for related scale of hardness（Machine is set when debugging）
When, control crossbeam stops movement, is kept for 5 seconds；Control moving beam to rise, just test force is steadily unloaded within the 2-3 seconds, this
When, hardness number can be locked, and be recorded；Kept for 2 seconds, control crossbeam is lifted off sample.Test is completed.
Wherein：The first test force of test is caused by preloading spring, and master trip power is direct by electronic universal tester
Apply；Hardness number measurement is by pressure head sheath and pressure head in test process, produces relative displacement, and then promote measurement bar
Pendulum, and measurement bar is swung after 5 times of this displacement equations under displacement measurement as caused by digital scale of hardness enters to be about to measurement bar right-hand member
Come, be transferred in the program of computer and handled and recorded.Caused relative displacement can be clear before first test force for pressure head sheath
Zero, record is relative displacement after first test force, that is to say the depth of cup after first test force.Pass through lever amplification 5
Handle again, and the hardometer before people carries out the metering system of depth of cup.We simply digitize herein.
The beneficial effect that the utility model is reached is：
1. this product is effectively to be combined electronic universal tester with hardness test device, the hardness test of a new generation is produced
