Temperature-Controlled Cable Testing With Dynamic Stretching

The patent introduces a stretching mechanism that dynamically adjusts the cable position during heating. The bidirectional reciprocating screw rod driven by the turbine enables the cable to be stretched and repositioned periodically, preventing adhesion to the heating mold inner wall while maintaining simple heating operation. This dynamic adjustment transforms the static heating process into a controllable dynamic process that ensures uniform heating.

The stretching mechanism acts as an intermediary between the cable and the heating mold. By introducing this intermediate device, the cable is kept at a controlled distance from the mold inner wall through stretching, preventing direct contact and adhesion. This intermediary mechanism resolves the contradiction by enabling both simple heating operation and uniform heating distribution.

The patent replaces complex mechanical stretching systems with a fluid-driven turbine mechanism. The bidirectional reciprocating screw rod coupled with the turbine converts rotational motion into linear reciprocating motion, achieving cable stretching through a relatively simple mechanical configuration. This substitution reduces device complexity while maintaining effective cable stretching for uniform heating.

The stretching mechanism is designed to serve multiple functions: it stretches the cable, prevents adhesion, and enables periodic repositioning during heating. By consolidating these functions into a single integrated mechanism driven by the bidirectional screw rod and turbine, the patent avoids the need for multiple separate devices, thereby reducing overall system complexity while achieving heating uniformity.

The patent implements periodic cooling action through the bidirectional reciprocating screw rod mechanism. During the heating phase, the cable is stretched; during the cooling phase, the mechanism enables rapid heat dissipation by adjusting the cable position or exposing it to cooling surfaces. This periodic action between heating and cooling phases reduces overall cooling time and increases productivity without requiring a completely separate complex cooling system.

The stretching mechanism operates continuously throughout the heating and cooling cycles, maintaining useful action. Rather than having separate heating and cooling systems, the same mechanical structure facilitates both processes by continuously adjusting the cable position. This continuity eliminates idle time between heating and cooling operations, improving productivity while avoiding the complexity of entirely separate systems.
