LD32 system microcomputer controlled electronic tensile and torsional testing machine
Product details
This tensile and torsional testing machine can achieve conventional locking torque testing, torque loading testing, axial force loading testing, as well as high locking torque testing, loosening torque testing, twisting torque testing, pre tightening torque testing, and loosening torque testing for self-locking nuts; The pre tightening force unloading method uses an axial force sensor to unload the axial force through a self unloading device without rotating the nut.
The testing machine is equipped with a three jaw chuck, and during the test, it is necessary to fix the fixture with the nut sample and then clamp the fixture with the nut sample on the three jaw chuck. The testing machine is equipped with an axial force unloading device, which works by unloading the axial force without rotating the nut specimen after the axial loading force. The main structure of the testing machine consists of a power device, an axial force unloading device, and a fixed clamp head. The axial force unloading device can move flexibly and does not require an axial force unloading device during testing. This device can be used to unload the axial force
Move to the back of the host; When conducting a high lock nut test, move the axial force unloading device between two three jaw chucks and then clamp the specimen for testing.
The testing machine is easy to operate, precise in control, and easy to maintain, greatly improving testing efficiency,

Main features:
Once screwed in and out, the test bolt is moved to the high lock nut locking position, and then installed on the testing machine. The relevant parameters are set, and the testing machine automatically performs the screw in and screw out test.
Lemon breaking torque test: Screw the test bolt into the locking position of the high lock nut, then install it on the testing machine, set the relevant parameters, and start the test. The test is completed when the driving part of the high lock nut is broken. The maximum torque when the driving part of the high pin nut is broken during the test is read as the breaking torque.
Pre tightening force test: When the high lock oyster mother is twisted, the maximum force value displayed on the testing machine's axial force channel is the pre tightening force of the high lock nut.
Loosening force test: After testing the pre tightening force, remove the axial load by not rotating the nut. Then tighten the oyster mother tightly, and the maximum torque required to rotate the nut is the loosening torque of the high-speed rail nut.
