AI Technical Summary
Existing thermal straightening fixtures have shortcomings in temperature control and pressure application, resulting in uneven heating of composite material parts, local overheating, or insufficient straightening. They also have poor versatility and are difficult to adapt to parts of different shapes and sizes.
It employs uniformly distributed micro heating wires and infrared radiation coated heating plates, combined with temperature sensors to achieve precise temperature control. Furthermore, through independently controlled hydraulic telescopic rods and pressure sensors, the pressure is adjusted according to the deformation requirements of the workpiece, ensuring uniform heating and precise pressure in all parts.
It achieves uniform heating and precise pressure control of composite material parts, improves the straightening accuracy and the applicability of tooling, and avoids problems such as local temperature difference and insufficient or excessive pressure.
