Description
Technical field
The utility model relates to testing equipment field, in particular to a kind of electric bending testing machine is particularly used for
Cement bright degumming glue sand or the testing machine of other nonmetallic fragile material flexural strength detections.
Background technique
With the development of life, requirement of the people to building is higher and higher, and therefore, the requirement to building materials equally also increasingly increases
Height, and the requirement for these building materials then needs some detection devices to detect.Electric bending testing machine is mainly as cement
Factory, building unit and related professional universities and colleges R&D institution making cement bright degumming glue sand flexural strength, which are examined, to be used, and can make other
The flexural strength of nonmetallic fragile material is examined.
For existing electric bending testing machine, operating procedure is as follows:
(1) power on, press the button on travelling counterweight, with the dynamic travelling counterweight of hand push, make counterweight upstream target of moving about
The zero curve of zero curve alignment scale, decontroling the zero curve being aligned after button can be moved, and hand can be used in the annular knurl of screw rod right end at this time
Partial turn screw rod, mobile travelling counterweight, is overlapped two zero curves；
(2) adjustment contacts it with travelling counterweight, then again in the zero setting contact screw for raising angle indicator board back position
It with nut check zero setting contact screw, proofreads whether vernier is overlapped with the zero curve of scale, if not being overlapped, zero setting touching should be readjusted
Head screw is until being overlapped；
(3) lock-screw is unclamped, mobile large and small balanced weight makes main lever tend to balance as far as possible, then tightens locking screw
Nail, big balanced weight is lock on main lever, the nut on mobile small balanced weight, keeps small balanced weight mobile until main lever is complete
Until balance, then small balanced weight is lock on main lever with lock-screw, notices that the locking of large and small balanced weight must can
It leans on, in case in use since test specimen is broken, main lever is shaken and destruction of balance when falling；
(4) examination body is put into bend-proof clamp, is aligned with the alignment sheets on fixture, the handwheel below rotary clamp, under making
Loading roller on trying to stop people from fighting each other is contacted with examination body, and continues to rotate certain angle, is had main lever and is centainly raised angle, numerical value is generally by experience
Estimation, principle are that examination body is in a horizontal position main lever as far as possible in fracture, and the numerical value for raising angle can be on raising angle indicator board
It reads；
(5) start button is pressed, machine starts loading, and when examination body is broken, main lever, which falls, touches limit switch, disconnects electronic
Electromechanical source, reading.
For electric bending testing machine in the prior art, there is the mistake of adjusting main lever balance in use
Journey, therefore, to assure that main lever is in level segment, but the process is often operator by subjective experience, observes and judges it
Whether horizontal, it more can not intuitively reflect true level condition, main lever more can not accurately be leveled.
