Metal Wire Torsion Testing Machine

HZ-4012B metal wire torsion testing machine,is one of new metal wire torsion testing machine studied and produced by our company by digital display and count. It is mainly used for theФ3.0～Ф10.0 metal wire torsion testing machine. The function of which is determination of metal wire to withstand severe plastic deformation in one-way or two-way reversed ability and display of wire surface and inner defect.

Standard

Speed option please follow table 3 of GB/T239-1999.

Technical Parameters

Working term:
3.1 room temperature within 10～35℃
3.2 On steady work table. install correctly, parallelism less than 0.2%.
3.3In the absence of vibration environment；
3.4 non - corrosive media in around；
3.5 power: three phrase four line 380V±10% 50Hz；voltage fluctuations:Fluctuations not exceeding ±


Construction and working principle
HZ-4012B metal wire torsion testing machine is made from engine part and electrical part. Count from the original mechanical structure to electronic counting, counting the minimum value of up to 0.1, test of axial Afterburner, Rotating Afterburner, test specimen is disconnected number of latches, termination tests are controlled by the electronic circuit, Simple and convenient operation.
4.1 Right end of the machine for axial removable Chuck,chuck mobile uses a sliding bearing,small friction resistance,reliable guarantees of axial movement of flatness.Axial Afterburner uses a 10:1 lever weights Afterburner,weight precision of 0.1.The left side of the machine is the slider box,drag the slider box by 0.5KW motor,enable it to move around,slider boxes by double - speed motor, gearbox, optical code disc and rotating Chuck composition.Left side of the machine is equipped with the left limit switches, guarantee the safety of equipment.
4.2 electric system:The power pack, control part, LED display - part,see chart



3, usage and operation
6.1 prepare for specimen
a. The length of test specimen follows the principles of GB/T239-1999 metal wire torsion testing method.
1.0～＜ф5.0 L=100d Ф5.0～Ф10.0 L=50d
The length of both side of chuck clamping is 30mm, all in together 60mm.
b. The test specimen must be straight by any possibility. Please make it straight on hand when necessary. If it won’t work when you do this like that, please put the specimen on the wood, plastic or copper, and hit it with hammer which material is the same as the specimen, or you can use other method to make it straight slightly, but please don’t damage the specimen’ surface and torsion it too. Part of specimen curved can not be used for test.
