Continuous extruder

Abstract

The invention relates to a continuous extruder. The invention relates to a continuous extruder. A frame of the continuous extruder is provided with two extrusion wheels, wherein the extrusion wheels have two rotating shafts parallel to each other. The two extrusion wheels have opposite rotation directions. Wheel rims of the extrusion wheels are respectively provided with at least an extrusion wheel groove in a circumferential direction. The extrusion wheel grooves are respectively provided with a guide seat matched with the same. The guide seat forms an extrusion chamber for passing through blank materials with the extrusion wheel groove. A die holder is arranged between the extrusion wheels. A channel for passing through a cable is arranged in the die holder. Two sides of axial core line of the die holder are symmetrically provided with holes communicated with the extrusion chamber along a radial direction, wherein the holes are communicated with a cover chamber. An outlet of the cover chamber is covered a periphery of an outlet end of the cable in the channel. With the present invention, extrusion blank materials enter the extrusion chamber and then enter the cover chamber. Because the holes are arranged symmetrically in the radial direction of the die holder, the extrusion blank materials can simultaneously enter the cover chamber in an upper position of the die holder and a lower position of the die holder so as to reduce a channel of the blank materials and provide small temperature difference of the blank materials, such that the blank materials flowing through the die holder is sufficient so as to improve output.

Description

[0001] The present invention is a divisional application of an invention patent with an application date of July 8, 2009, an application number of 200910144064.8, and an invention title of "extrusion machine". technical field [0002] The invention relates to a continuous extrusion machine, in particular to an extrusion equipment for forming metal through continuous extrusion. Background technique [0003] At present, due to the large diameter of the metal outer sheath of the ultra-high voltage cable, it is generally formed by welding a metal strip, that is, seam welding. The material grains at the welding place of this welding method are coarse and uneven, which affects the electrical and electrical properties of the cable. mechanical physical properties. The continuous aluminum pressing machine produced with aluminum ingots has huge equipment, high energy consumption, complex structure, and high cost, while the traditional continuous continuous extrusion machine has a stru...
