Winding and twisting testing machineThe winding and twisting test machine is commonly used for conducting winding and twisting tests on wires and cables such as aluminum wire, steel wire, steel pole, and steel core 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 is an essential testing tool for steel core aluminum stranded wire manufacturers, which can meet 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 and reduce investment for users.

Twisting test machine for winding and twisting (can refer to standards such as GB/T4909.7-2009, GB/T3428-2002, etc.)

Rotate the black handle with a disc next to the right gripper to separate it from the travel switch, ensuring that the machine is powered on.

Tighten the circular small knob on the side of the right gripper so that it does not rotate when making a twisted sample. Then, based on the length of the sample between the left and right clamps, lock the fixture seat on the right guide rail with the guide rail.

2.1 Sample length: The original gauge length dimensions can refer to GB/T4909.4-2009,4.3 and GB/T3428-2002, 10.3, where b is 100d.

2.2 Counterweight load: Choose a suitable counterweight (load force can refer to GB/T4909.4-2009, 5.2 and GB/T3428-2002, 10.3, b should not exceed 2% of the tensile strength of the specimen).

2.3 Twisting times and speed: The twisting speed of the winding twisting test machine generally does not exceed 60r/min (refer to GB/T4909.4-2009, 5.4 and GB/T3428-2002, 10.3, b), and the twisting times should not be less than the specified values in Table 3, Table 4, and Table 5 of GB/T3428-2002. During the winding and twisting test machine, bend both ends of the sample at a 90 degree angle and clamp it onto a three jaw clamp. Then press the "forward" button, the machine rotates counterclockwise, and the counter starts counting. When the sample is twisted, the right gripper moves to the right under the pulling of the counterweight, and the right gripper contacts the travel switch, and the counter stops counting.

2.4 Test completed: Open the left and right clamps to remove the wire and disconnect the power supply.
