摘要： A method and apparatus are provided for continuously extruding rod feedstock through a die orifice while gripping two opposed sides of the feedstock to a pressure greater than the yield strength of the material with means for applying lubricant to the ungripped surfaces, constraining walls between which the feedstock is fed in the gripped condition, a stop at one end of the constraining walls, and a die orifice near the stop through which the feedstock is extruded, said lubricant applying means including at least two cylinders each having an open end facing a respective one of the ungripped surface when the apparatus is in use and means for introducing compressed gas into each of the cylinders.
摘要翻译：提供了一种方法和装置，用于连续地挤出棒材原料通过模孔，同时将原料的两个相对的侧面夹持到大于材料的屈服强度的压力，其具有将润滑剂施加到未被弯曲的表面的装置，约束壁之间的原料在夹紧状态下进给，在约束壁的一端处设置止动件，在靠近挤出的原料的止挡件处的模孔，所述润滑剂施加装置包括至少两个缸体，每个缸体的开口端面向相应的一个当设备使用时的未被夹紧的表面和用于将压缩气体引入每个气缸的装置。

摘要： An extrusion machine is disclosed wherein wax or other suitable lubricant is applied to the side of the feedstock contacting the shoe of the extruder. A stick of wax may be supported in a cylinder having an open end facing the feedstock; the stick is a loose sliding fit in the cylinder and compressed gas introduced into the cylinder applies a substantially constant biassing force urging the stick into engagement with the feedstock and at the same time, by leaking between the stick of lubricant and the cylinder, cools the stick of lubricant to inhibit melting.
摘要翻译：公开了一种挤出机，其中将蜡或其它合适的润滑剂施加到与挤出机的鞋接触的原料侧。蜡棒可以在具有朝向原料的开口端的圆筒中支撑; 该棒是在气缸中松动的滑动配合，并且被引入气缸中的压缩气体施加基本上恒定的偏压力，以推动棒与原料接合，并且同时通过在润滑剂棒和气缸之间的泄漏来冷却润滑剂棒抑制熔化。
