锻件毛坯三段式加热工艺方法

本发明提供了一种锻件毛坯三段式加热工艺方法，包括：将待加热的金属毛坯推送至预热段内，并实时检测金属毛坯在预热段内的表面温度；当金属毛坯在预热段内的表面温度大于第一预设温度值时，将金属毛坯推送至加热段内，并实时检测金属毛坯在加热段内的表面温度；当金属毛坯在加热段内的表面温度大于第二预设温度值时，将金属毛坯推送至保温段内；第二预设温度值大于第一预设温度值，且保温段的保温温度与加热段的加热温度之间的差值小于预设差值；在金属毛坯在保温段内保温预设时长后，将金属毛坯推送至冲压装置进行冲压。该方法可以使得金属毛坯的内外温度分布趋于均匀，使得金属毛坯的温度更加符合工艺要求。 The invention provides a forged blank three-stage type heating process method. The method comprises the steps that a to-be-heated metal blank is pushed into a preheating section, and the surface temperature of the metal blank in the preheating section is detected in real time; when the surface temperature of the metal blank in the preheating section is higher than a first preset temperature value,the metal blank is pushed into a heating section, and the surface temperature of the metal blank in the heating section is detected in real time; when the surface temperature of the metal blank in the heating section is higher than a second preset temperature value, the metal blank is pushed into a heat insulation section; the second pres
