Product Overview
The CR-6 wire winding testing machine is mainly used to test the bonding strength and surface defects of the surface coating of
metal materials with and without coating after being subjected to winding deformation.
Technical parameters
Diameter range: 0.5-6mm
Winding speed: 15, 20, 60r/min
Overall dimension (mm): length × wide × high
seven hundred × three hundred and sixty × nine hundred and fifty-five
Self weight (kg): 300
Test steps
a. Select the corresponding mandrel and install it on the chuck, and press it tightly with the two screws on the chuck. If self winding
is done, use a flat pliers to clamp the wire, and pay attention to alignment;
b. Select a suitable sample, knock it straight, and use a randomly equipped elbow wrench to bend one end of the sample;
c. When it is necessary to hang heavy thallium at the end of the sample, one end of the wire can be inserted into the corresponding
hole on the clamp or jaw, and the other end can be hung down through a follow-up bracket. A loop should be bent at the end to hang
the machine hook tray down, and a corresponding weight not greater than 2-5% of the nominal breaking force of the wire can be
added. For wires with high strength and large diameter, sometimes hanging heavy thallium is limited by the space of the testing
machine, and can be appropriately clamped with flat pliers for winding;
d. When holding one end of the wire by hand for testing, a guide wheel can be used to support the wire, and the applied tension
should be based on the minimum tension that can make the wire close to the core shaft;
e. After determining the direction of rotation, close the clutch and press the pedal of the foot switch. At this time, the motor starts.
Due to the low speed, the operator can count the number of turns. When the number of turns meets the requirements, lift the pedal,
stop the motor, open the clutch, and wait for the twisting force on the spindle to disappear before removing the sample. Sometimes,
due to high torque after the sample is wrapped, the clutch cannot be opened. At this time, a switch can be used to reverse click it;
f. After the experiment is completed, make timely records.
