Jiangsu Kaiyuan Testing Equipment Co., Ltd. (Jiangdu Kaiyuan Testing Machinery Factory) is a professional manufacturer of material testing machines. With years of production experience, strong hardware and software development capabilities, as well as mechanical design and development capabilities, we have a strong team of high-level and mid-level engineering and technical personnel in areas such as automatic control, software programming, mechanical hydraulics, material testing, marketing, production management, electrical testing and assembly. The enterprise has supporting mechanical processing methods such as cars, pliers, milling, grinding, and wire cutting, with excellent technology. The experimental machine has been designed and completed in a "one-stop" manner.

Main products of the company: tensile machines, rubber tensile machines, rubber tensile machine manufacturers, belonging to tensile machines, belonging to tensile machine manufacturers, tensile testing machines, tensile testing machines, safety rope static load tensile testing machines, winding and twisting testing machines, cross-linked cable slicing machines, rubber planing machines, rubber static stiffness testing machines, etc.

Briefly describe the operation method of the 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.

5. Determination of experimental results:

1) Test results: Check the surface of the test part of the specimen with normal vision and record it.

2) Evaluation: If the test results of each sample comply with the relevant product standards, it is judged as qualified.
