发明名称 Device for extruding hollow articles
摘要 In a device for extruding hollow articles, e.g. tubes, the die is rotatably mounted in the die holder. The die has a hole for shaping the external surface of the tube. The axis of said hole is eccentric relative to the axis of the external surface of the die holder. The device comprises a needle for shaping the internal surface of the tube, the needle entering the die hole during the process of extrusion. The needle axis coincides with the extrusion axis. The die holder is made of at least two bushings, installed one inside the other. The axes of the internal surfaces of the bushings are offset relative to the axes of their external surfaces. The bushings are capable of turning for adjusting the position of the die hole axis relative to the needle. This design of the die holder makes it possible to minimize the eccentricity of the axes of the internal and external surfaces of the tubes extruded in the device realized according to the present invention and installed in a conventional press.
