在本实施例中，上模固定板3用以固定支撑热校正轴锻件上模4，当需要对高温轴锻件进行锻造切边时，将轴锻件放置于热校正轴锻件下模2内，此时将热校正轴锻件上模4向靠近热校正轴锻件下模2一端移动，使得热校正轴锻件上模4与热校正轴锻件下模2相紧贴压紧，对轴锻件进行热校正的同时，将自动切飞边组件5向下移动，通过自动切飞边组件5将轴锻件进行自动切除飞边，缩短轴锻件的锻造时长，提升了轴锻件的机械性能和使用寿命，切除的飞边料掉落至边料挡通板件7上，当需要将飞边料排出时，通过移动边料挡通板件7，使得位于边料挡通板件7上的飞边料进入至落料槽6，通过落料槽6将飞边料自动排出，无需人工清理飞边料，操作简单方便，自动化程度和生产效率较高。
结合图1所示，所述的热校正轴锻件上模4内设有热校正上模腔8，所述的热校正轴锻件下模2内设有热校正下模腔9，所述的热校正上模腔8与热校正下模腔9的位置相对应且形状相配适。
具体地说，热校正下模腔9和热校正上模腔8用以放置轴锻件，同时对轴锻件进行热校正，提高了轴锻件的质量。
结合图2、图3所示，所述的自动切飞边组件5包括若干设置于上模固定板3底部的除飞边切刀10，所述的除飞边切刀10可沿竖直方向直线往复运动，所述的除飞边切刀10与热校正轴锻件上模4相滑动配合。
本实施例中，当需要对轴锻件两端的飞边料进行去除时，将除飞边切刀10下移，通过除飞边切刀10对轴锻件两端的飞边料进行去除，去飞边简单方便。
结合图1所示，所述的上模固定板3底部还设有若干沿上模固定板3中心线对称的切刀限位板11，所述的除飞边切刀10位于切刀限位板11与热校正轴锻件上模4之间，所述的上模固定板3内设有若干沿上模固定板3中心线对称的第一直线驱动器12，所述的第一直线驱动器12的动力轴与除飞边切刀10相连。
本实施例中，当移动除飞边切刀10将飞边料进行切除时，启动第一直线驱动器12，通过第一直线驱动器12的动力轴带动除飞边切刀10移动，除飞边切刀10与热校正轴锻件上模4和切刀限位板11相滑动配合，通过切刀限位板11对除飞边切刀10进行限位作用，避免除飞边切刀10在切除飞边料的过程中，发生角度偏移，提高了切除飞边料的精确度，本领域技术人员应当理解，第一直线驱动器12可以是气缸、油缸或者是直线电机。

具体的说，驱动支撑立架13用以固定支撑边料挡托齿条板14，在进行飞边切除过程中，边料挡托齿条板14位于除飞边切刀10下方，切除后的飞边料自动落入至边料挡托齿条板14上，将飞边料进行承托，避免飞边料直接掉落至加工底座1和热校正轴锻件下模2，砸坏加工底座1和热校正轴锻件下模2，当需要将飞边料排出时，移动边料挡托齿条板14即可。
所述的边料挡托齿条板14呈倾斜设置，所述的驱动支撑立架13内设有与边料挡托齿条板14相啮合配合的启动转轮15，所述的驱动支撑立架13顶部设有边料上挡板16。

本实施例中，边料上挡板16靠近热校正轴锻件下模2一端呈斜面，可确保切除后的飞边料自动落入至边料挡托齿条板14，边料挡托齿条板14插入至齿条板第一对位槽17内，对边料挡托齿条板14起到支撑定位的作用，避免边料挡托齿条板14发生形变。
结合图1所示，所述的加工底座1上设有若干沿加工底座1上中心线对称的固定支板18，所述的固定支板18靠近热校正轴锻件下模2一端设有齿条板第二对位槽19，所述的齿条板第二对位槽19与边料挡托齿条板14的位置相对应且形状相配适。
本实施例中，在将位于边料挡托齿条板14上的飞边料进行排出时，移动边料挡托齿条板14，使得边料挡托齿条板14插入至齿条板第二对位槽19内，对边料挡托齿条板14起到定位的作用，对位精确。
结合图1所示，所述的固定支板18内设有限位槽20，所述的上模固定板3内设有延伸通入至限位槽20内的限位块21，所述的上模固定板3与固定支板18相滑动配合，所述的固定支板18上设有驱动安装座22，所述的驱动安装座22内设有第二直线驱动器23，所述的第二直线驱动器23的动力轴与上模固定板3相连。

本发明的工作原理是：
上模固定板3用以固定支撑热校正轴锻件上模4，当需要对高温轴锻件进行锻造切边时，将轴锻件放置于热校正轴锻件下模2内，此时将热校正轴锻件上模4向靠近热校正轴锻件下模2一端移动，使得热校正轴锻件上模4与热校正轴锻件下模2相紧贴压紧，对轴锻件进行热校正的同时，启动第一直线驱动器12，通过第一直线驱动器12的动力轴带动除飞边切刀10移动，除飞边切刀10与热校正轴锻件上模4和切刀限位板11相滑动配合，通过切刀限位板11对除飞边切刀10进行限位作用，避免除飞边切刀10在切除飞边料的过程中，发生角度偏移，提高了切除飞边料的精确度，缩短轴锻件的锻造时长，提升了轴锻件的机械性能和使用寿命，切除的飞边料掉落至边料挡通板件7上，当需要将飞边料排出时，当需要移动边料上挡板16时，启动电机，通过电机的转动轴带动启动转轮15转动，通过启动转轮15与边料挡托齿条板14之间的啮合作用带动边料挡托齿条板14移动，边料上挡板16可避免切除后的飞边料掉落至驱动支撑立架13外，使得位于边料挡通板件7上的飞边料进入至落料槽6，通过落料槽6将飞边料自动排出，无需人工清理飞边料，操作简单方便，自动化程度和生产效率较高。

具体的说，S1步骤中，当需要移动启动热校正轴锻件上模4时，启动第二直线驱动器23，通过第二直线驱动器23的动力轴带动上模固定板3以及热校正轴锻件上模4向靠近热校正轴锻件下模2一端移动，使得热校正上模腔8和热校正下模腔9相紧贴配合，进行热校正；S2步骤中，当需要移动自动切飞边组件5时，启动第一直线驱动器12，通过第一直线驱动器12的动力轴带动自动切飞边组件5移动，自动对轴锻件进行去除飞边料，并且通过边料挡通板件7对飞边料进行承托，避免飞边料直接砸落至加工底座1或热校正轴锻件下模2上，对加工底座1以及热校正轴锻件下模2表面造成损伤；S3步骤中，当需要移动边料挡通板件7时，转动启动转轮15，通过启动转轮15带动边料挡通板件7移动，使得位于边料挡通板件7上的飞边料自动掉落至落料槽6内，实现自动排料。
