Abstract
本发明涉及一种连续挤出装置,用于连续挤出装置的模具加热器本体组件(11)基本与EP-A-0071490中所述的装置类似,该模具加热器本体组件(11)包括:非磁性材料的模具块(15),用于挤出铜管;以及料斗部分(17),该料斗部分滑动配合地装入模具加热器本体(19)中。模具加热器本体(19)包括在陶瓷支承材料中的铜管线圈,该铜管线圈设有电有和冷却水连接件(23),以便通过电感应而将料斗部分(17)加热至大约700℃的温度。为了使电感应加热效果集中在料斗部分(17),低磁阻的磁性部件(25)和磁性材料端部块(33、35和37)将涡电流引向料斗部分(17)。从而防止靴形件由于加热而变弱。
Description
本发明涉及一种通过连续挤出方法来形成金属的装置,其中,原料被引入旋转轮的圆周槽中,以便进入形成于槽和弓形加工工具(该弓形加工工具伸入槽内)之间的通路内。
EP-A-071490公开了一种连续挤出装置,该装置具有:旋转轮,该旋转轮形成有圆周槽;靴形件装置,该靴形件装置包括弓形加工工具,该弓形加工工具限制了槽的径向外侧部分,该槽设有在模具本体中的出口孔;以及支座,该支座沿旋转方向离开出口孔。
根据本发明,靴形件装置设有模具块加热器本体组件,该模具块加热器本体组件包含模具加热器本体、挤出模具装置和电感应加热线圈组件,该电感应加热线圈组件布置成可通电,以便与和模具装置相连的可磁化装置共同作用,从而进行电感应加热。
优选是,磁性部件位于电感应加热线圈组件的外部,并用于限制电感应加热线圈组件外部的磁泄漏。
优选是,绝热材料位于磁性部件和靴形件装置的中间。
优选是,电感应加热线圈组件包括装入电绝缘材料中并设有电连接件以及用于冷却剂流的进口和出口连接件的螺旋缠绕铜管。
下面将通过实例介绍本发明,该实例将部分参考在EP-A-071490的图1和2中所述的连续挤出装置的普通结构;且主要参考布置成位于用于挤出铜管的靴形件(未示出,但是与EP-A-071490中所示的靴形件8类似)的矩形截面孔内的模具加热器本体组件11的附图、局部图、等角视图、分解图。
模具加热器本体组件11包括进口块13、模具块15、中心开孔的料斗部分17以及模具加热器本体19。
模具加热器本体19包括设置在陶瓷支承材料中的铜管螺旋线圈,以便形成电感应加热线圈组件21,该电感应加热线圈组件21设有电和冷却水连接件23,该电和冷却水连接件23穿过靴形件向后延伸。低磁阻磁性部件25位于电感应加热线圈组件21的外部,且通常由六毫米厚的“硅-铁”合金冲压件27形成,该“硅-铁”合金冲压件27有很高的饱和磁性,居里点超过800℃,该“硅-铁”合金冲压件27间隔开以便形成3毫米的间隙,并安装在中心开孔的基板29上。冲压件27的端部31与第一和第二磁性材料端部块33和35以及37连接,第二端部块35和37分开间隙39,以便限制涡电流循环。相应的间隙形成于基板29中。
进口块13形成有非磁性材料的模具块15,该模具块15与磁性材料的料斗部分17共同作用,该料斗部分17再以滑动配合与模具加热器本体19中的料仓41共同作用。销钉(未示出)将端部块33、35和37定位在靴形件装置上,同时允许有不同热膨胀。支座43在沿旋转方向离开通向中心孔的口45的位置处位于模具块15上,该中心孔布置成接收挤出模具(未示出),该挤出模具位于模具块15的料斗部分17中。
绝热材料例如云母制成的薄垫片47布置在端部块33、35和37、基板29和靴形件的中间,以便限制向靴形件的传热。
在操作中,当使进口块13、模具块15和料斗部分17布置在模具加热器本体19中以便形成模具加热器本体组件11,并布置在连续挤出装置的靴形件中,且将铜原料推向进口块13和模具时,通过使得大约12千瓦功率水平和大约50赫兹的电流通过电感加热线圈组件21,从而使得料斗部分17感应加热至大约700℃温度,以便通过导热而使模具温度保持在700℃,因此大大方便了通过模具的挤出处理。通过将电感应加热线圈组件21布置在模具块15附近,并通过低磁阻磁性部件25的作用而引导涡电流通过料斗部分17,将限制向靴形件的碳钢材料和相邻钢制品的磁泄漏,且大部分的输入能量被传递给模具块15,并将所形成的热能传导至铜供给材料,而不会使得靴形件的温度升高,且不会显著影响靴形件承受大约300吨径向负载的能力,该300吨径向负载用于在模具处获得大约500兆帕的所需挤出压力。感应加热模具块26避免了对连续挤出装置的相邻部分的较大加热,从而避免了由于升高温度而引起的结构材料机械特性降低。
应当知道,尽管前面所述涉及连续挤出机器的径向挤出结构,但是本发明也可用于使用切向挤出结构的机器,且在第二端部块35和37以及相关冲压件27之间的间隙39的尺寸设置成适应该切向结构。
此外,应当知道,模具加热器本体19的结构为在正常供电频率下操作的非常紧凑的装置。该紧凑装置只需要在靴形件中的很小孔,从而减小了由于设有该孔而对靴形件的削弱。利用正常供电频率将不需要提供用于增大频率的电流和因此产生的成本。
还应当知道,尽管前述说明涉及铜材料的挤出,本发明还可用于其它材料的挤出。对于材料例如铝,当利用磁性材料的模具腔室时,可以省略料斗部分17,这样,可以利用直接感应加热的较大模具块。
