Abstract

The invention relates to a continuous extrusion device, the frame of which is equipped with two extrusion wheels with mutually parallel rotating shafts. Opposite in rotating directions, each of the extrusion wheels has respectively at least one circumferential extrusion wheel groove on wheel rims. And the extrusion wheel grooves are respectively provided with a mating guide base. The guide bases and the extrusion wheel grooves together form extrusion cavities for passing blank materials. A die holder is installed between the extrusion wheels, and a channel is positioned inside the die holder for cables. Holes communicated with the extrusion cavities are symmetrically arranged on two sides of the axial core wire of the die holder along the radial direction. The holes are also communicated with a coated cavity of the die holder, and the outlet of the coating cavity is coated at the periphery of the cable outlet end in the channel. After entering the extrusion cavities, the blank materials for extrusion get into the coated cavity through the holes on the die holder. As the holes are arranged symmetrically along the radial direction of the die holder, so the blank materials for extrusion get into the coated cavity simultaneously from the upper and lower positions of the die holder. Thus, the channel for blank materials is shortened, and the temperature difference is small. With sufficient blank materials passing through the die holder, the device of the invention has increased output.

Description

Continuously extruded device
The present invention is to be on July 8th, 2009 applying date, and application number is 200910144064.8, and denomination of invention is divided an application for the patent of invention of " extruder ".
Technical field
The present invention relates to a kind of continuously extruded device, is a kind of by the continuously extruded extrusion equipment that makes metal forming specifically.
Background technology
At present, the cable metal oversheath of super-pressure because caliber is big, generally all adopts the metal tape welding fabrication, and seam welding is promptly arranged, and the material crystal grain of this welding method weld is thick, and is very inhomogeneous, influences the electric and mechanical and physical performance of cable.Huge with the continuous aluminium press equipment that aluminium ingot is produced, energy consumption is big, complex structure, involve great expense, and traditional continuous continuously extruded device, it all is the structure of single groove of single-wheel or single-wheel double flute, this structure is simple relatively, because this equipment has only a runner, its extrusion chamber has only a Kong Yuqi to communicate, so the runner of blank in extrusion chamber is long, cause upper and lower temperature difference big, product percent of pass is low, and the structure of single groove of this single-wheel or single-wheel double flute can only be produced the product of little caliber, small bore usually, it is very big to produce big caliber product difficulty, and yield rate is low.
Summary of the invention
The purpose of this invention is to provide a kind of runner weak point, have a narrow range of temperature, can produce the continuously extruded device of the cable seamless metal sheath of big caliber.
For achieving the above object, the present invention has adopted following technical scheme: continuously extruded device comprises frame, two squeegee rollers that rotating shaft is parallel to each other are set on the frame, be respectively equipped with the extruding race of at least one circumferencial direction on the opposite and wheel rim of the rotation direction of squeegee roller, be respectively equipped with the guide bracket that matches with it on the extruding race, guide bracket and squeegee roller groove form the extrusion chamber that passes through for blank, be provided with die holder between the squeegee roller, the inside of die holder is provided with the passage that current supply cable passes through, the both sides of die holder shaft core line radially are arranged with the hole that communicates with extrusion chamber, the hole communicates with the coating chamber of die holder, and the outlet that coats the chamber is coated on the periphery of the cable outlet end in the passage; Rotating shaft one end of squeegee roller is provided with transmission mechanism, and the other end is provided with the screw thread that matches with hydraulic nut, and the middle part is provided with the spline that matches with squeegee roller.
As shown from the above technical solution, continuously extruded device of the present invention is provided with two squeegee rollers that rotating shaft is parallel to each other on frame, be provided with die holder between the squeegee roller, extrusion billet enters extrusion chamber and coats the chamber after the hole on the die holder enters, because the hole is symmetrically arranged in the radial direction of die holder, so on die holder, the upper/lower positions place has extrusion billet to enter extrusion chamber simultaneously, when squeegee roller is worked like this, blank has the charging simultaneously of two points at least at the circumferencial direction that coats the chamber, shortened the runner of blank, and have a narrow range of temperature, the flow through blank abundance of die holder, product quality is improved, and has avoided local scarce material effectively and the depression that causes and the appearance of crackle for the tubing of big caliber, and output also is improved simultaneously.
