Winding and twisting testing machineCommonly used for winding and twisting tests on wires and cables such as aluminum wire, steel wire, steel pole, and steel cored aluminum stranded wire. Meets the requirements of GB/T4909.4-2009 "Test Methods for Bare Wires - Torsion Test" and GB/T4909.7-2009 "Test Methods for Bare Wires - Winding Test" standards. Complies with GB/T3428-2002 GB/T3428-2012。 For aluminum wire, steel wire, and copper rod, winding and twisting tests are required. It is an essential testing tool for steel cored aluminum wire manufacturers.

The winding and twisting test machine meets the requirements of GB4909.4-2009 "Test Methods for Bare Wires - Twisting Test" and GB4909.7-2009 "Test Methods for Bare Wires - Winding Test" for situations where aluminum wires, steel wires, and copper rods need to be wound and twisted. It can be used for multiple purposes, reducing investment for users. It is an essential testing tool for steel cored aluminum wire manufacturers.

Operation method of winding torsion testing machine:

1. Sample length: Cut two samples from the surface inspection qualified sample, and the sample length should meet the specified number of winding turns. (Refer to GB/T3428-2002, 10, 3, c and GB/T4907, 7-2009, 5, 4, which generally have 8 turns)

2. Selection of winding rod: Select the winding core rod according to the standard specified winding diameter (refer to Tables 3, 4, and 5 in GB/T3428-2002), use a wrench to open the left clamp (three jaw chuck) to clamp the left end of the core rod, rotate the circular small knob on the side of the right clamp to allow the right clamp to rotate freely, and adjust the distance of the right clamp to clamp the right end of the core rod. Thread the wire through the wire plate and tighten the left clamp wedge pressure head to press one end of the wire. Manually wrap half a circle on the core rod, and clamp the other end with the wire plate to keep the sample in a tight state.

3. Speed adjustment: Open the "forward" button and adjust the speed (refer to GB/T4909, 7-2009, 5, 4 for speed not exceeding 10 times/minute, and GB/T3428-2002,10, 3 for speed not exceeding 15 times/minute in C). The machine rotates counterclockwise to evenly arrange the wires on the core rod in a spring shape as the effective sample. After the number of turns of the wires reaches the standard, press the "stop" button to stop the machine from winding.

4. Test completed: Open the left and right clamps, remove the core rod, retract the wire, and disconnect the power supply.

Introduction to maintenance of winding and twisting testing machine:

1. When the winding torsion testing machine malfunctions, please promptly contact our company's after-sales service personnel.

2. Operators must be trained and qualified before they can work. Non test personnel are not allowed to operate to prevent damage to the instrument and personal injury.

3. During the operation of the gripper, the operator should not touch it. The winding and twisting testing machine has completed the test, and the interior of the gripper has been cleaned thoroughly.

4. The rotating parts have been lubricated with oil before leaving the factory, and maintenance should be done after a period of use.

5. Please handle the winding and twisting testing machine with care during transportation to prevent damage to the components.

6. When the winding and twisting testing machine is not in use for a long time, the product should be powered on and operated every half month for at least half an hour.

7. The ambient temperature around the winding and twisting testing machine is 8 ℃~25 ℃, and the humidity is ≤ 70%. Laboratories that do not meet these conditions can be equipped with air conditioning.
