Equipment Description:


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. It is a reliable measure

instrument for producing and using wire units.


Construction and Working Principle:

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

Installation and Debugging:

5.1 The device out of the box,p laced on the cement floor of a high 500mm,placing environment cannot

have corrosive media,Use the accuracy of not less than 0.05mmm level,Horizontal adjustment of the

device to no more than 0.2 per thousand level,P20 with seven core plugs at both ends of the join line in

the two P20 seven core socket Topspin tight,P20 join line plugged in 4 core 4 core P20 socket Topspin tight,

under the tray s vibration reduction in weight,seat vibration reduction of 4 - core aerial plug in 4 core air outlet.

Labeled "“  ” " screw connection on a wire,wire the other end of the Earth,socket location above see

attached map

5.2  Plug in the power of zero line on the 4 - wire three - phase power ~380V and socket,left main power

switch on the device push the digital display 000.0,about Control Panel on the left and right line select switch

reset in any location,click the " test " pushbutton switch,Look move slider box direction is consistent with

the direction of the reset switch,slider box to the left hand orientation to left,move contrary to the right,

If inconsistent power plugs with two line can be reversed,pressing the test button green switches without

movement or abnormal sound,Immediately turn off main power switch,Check whether three - phase four

- wire zero line phase or not,Be connected as required after power on,figure for the location in the above

sections, see picture 1.

5.3 adjust height of weight plate:

Observation on the right side when the weight of the pallet in the free - hanging position whether landed

on the seat vibrationreduction,If gap please see picture 1,adjust adjusting screw,weight tray landed on

the seat vibration reduction.And then hand pulling Chuck lever at horizontal position,observe weight tray

left vibration reduction,digital Lock switch up,fails to leave a vibration reduction,adjusting screws on the

fastening device,Pull - wire - rope vibration reduction of drag - and - plate left,twist firmly fixing screws

on the device,let weight tray free fall,see if landed on the seat vibration reduction.So repeatedly adjust

when makes weight tray free fall drop on the vibration reduction,vibration reduction of leverage when in

horizontal position left.

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.

6.2 install and nip the specimen

1.Selected based on specimens of soft and hard splint,select two specimens of hard Groove plywood,

sample soft select a Groove of the other is raised,when the splint is selected,will push the splint into the

two chuck’ holes.Choose plywood by harder of specimen. Two groove plywood can be use if the specimen

is hard,

2.Turn on main power switch LED display 000.0. According to the length of the specimen and the distance

Chuck,the left and right line switch reset in the appropriate location,pressing the green test button,make the

distance

Chuck to a suitable location,plug one end of a specimen Chuck 30mm,with the six - party move hand rotating

Chuck in the screw under the M20,align the center of the specimen clamping head Middle,and then use the

move within the six - party screws that hold the hand above the rotating Chuck M20,and repeatedly adjust the

two screws,after the centerline of the specimen at Chuck tightening screw clamp, tightening the other end of

the specimen in the same way.

3.Specimen axial tensile force and reverse speed select. According to GBT239-1999 requirements.To make

the test piece during the test process is straight,should be subjected to some form of pulling force.This

experimental nominal tensile strength of wire tensioning force shall not be greater than the corresponding

value of 2,weight of the test machine using 10:1 lever Afterburner, the afterburner size equal to weight

nominal value X10.

Meet Standard:

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