The eco-friendly spring wire is a device power connection wire that utilizes stretchability to work. Generally made of TPU material cable, it is used to control the power connection of the movement of the movable equipment, which can quickly rebound and restore its shape in a short time. Widely used in mobile power connection equipment such as automobiles, machines, telephones, instruments, etc. According to the material: PU spring wire, PVC spring wire.

PU material is the best material for spring wire. It has the characteristics of flame retardant, oil resistance, acid and alkali resistance, low temperature resistance, UV resistance, wear resistance, hydrolysis resistance and aging resistance. As the preferred material for spring wire, it is more and more widely used. . The spring line elasticity of PVC material is a little lower than that of PU, and it is suitable for ordinary machinery and equipment power supply cables.

Main use

①PU/PVC sheathed (shielded) spring wire for control system: used in CNC machine tools, production lines, logistics systems, robots, etc.;

②PU/PVC sheathed (shielded) spring wire for power system: used in processing equipment, cranes, production lines, etc.;

③ PU/PVC sheathed (shielded) spring wire for data/bus transmission: used in CNC machine tools, production lines, logistics systems, robots, etc.

size

(1) Spring wire diameter d: the diameter of the cable used to manufacture the spring wire;

(2) Spring coil diameter D: the maximum outer diameter of the spring wire;

(3) The inner diameter of the spring wire D1: the minimum outer diameter of the spring wire;

(4) Spring wire helix length L: the static length of the spring wire without external force;

(5) The working length of the spring wire L0: the dynamic length of the spring wire when it sits down under external force;

(6) The length A of the spring wire: the total length of the straight line required to wind the spring wire;

(7) The length of the tail of the spring wire: the tails at the two ends are represented by L1 and L2 respectively;

Matte spring wire, bright spring wire, under normal circumstances, the matte spring wire is easier to form than the bright spring wire. And the matte spring wire will not turn yellow during the heat treatment process, so the matte spring wire is more expensive than the bright spring wire!

The matte spring wire is generally used in the military, and the bright spring wire is generally used for power connection of various machinery and equipment.
