AI Technical Summary

Technical Problem

In the existing hot spinning process of magnesium alloy curved generatrix components, uneven temperature control leads to uneven plastic deformation, large wall thickness deviation, and fluctuations in mechanical properties, affecting product qualification rate and service reliability.

Method used

A dual-path flame system and multiple temperature sensors are used to monitor the temperature of the inner and outer sides of the magnesium alloy slab and the curve generatrix in real time. The heating power and heating position are dynamically adjusted by the control system to ensure that the local temperature fluctuations during spinning are within the set range, thus achieving isothermal spinning.

Abstract

The present application belongs to the technical field of magnesium alloy isothermal hot spinning, and mainly provides a magnesium alloy curved generatrix component isothermal spinning temperature control method and equipment. The method comprises the following steps: preheating the spinning die; clamping the magnesium alloy slab on the spinning machine, then starting the spinning machine to drive the magnesium alloy slab and the spinning die to spin; collecting the temperature of the inner and outer sides of the magnesium alloy slab and the curved generatrix in real time, and starting the spinning process when the temperature reaches the set range; dynamically and synchronously heating the magnesium alloy slab according to the spinning wheel motion track of the spinning machine; during the spinning process, the control system dynamically and synchronously adjusts the heating power, so that the temperature fluctuation of the local deformation area generated by the spinning motion is controlled within the interval of 50 DEG C lower than the lower limit of the set range and 50 DEG C higher than the upper limit of the set range. Through dynamic and synchronous adjustment of the heating power, the local area temperature fluctuation is small, which is better than the traditional flame heating method.
