Embodiment Construction

[0056] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0057] refer to figure 1 , figure 2, is a kind of straightening machine disclosed by the present invention, comprising a cabinet 1, a plurality of driving wheel groups and a plurality of driving wheels 3 arranged in the cabinet 1, one side of the cabinet 1 is hinged with a cabinet 1 door, and a plurality of driven wheels 2 are arranged side by side Setting, a plurality of driving wheels 3 are also arranged side by side. The driving wheel 3 is arranged on the upper side of the driven wheel 2, and the driving wheel 3 and the driven wheel 2 are alternately arranged; the two sides of the chassis 1 are respectively provided with perforations 4 for the casting rod to pass through, and the driving wheel 3 and the driven wheel 2 touch each other. When the straightening machine straightens the casting rod, the casting rod enters the cabinet 1 through the hole 4 on...

Abstract

The invention relates to a straightening machine and a copper-chromium-zirconium alloy contact line production process. The straightening machine comprises a machine box, a plurality of driven wheelsand a plurality of driving wheels, wherein the plurality of driven wheels and the plurality of driving wheels are arranged in the machine box, a machine box door is hinged to one side of the machine box, the plurality of driven wheels are arranged side by side, and the plurality of driving wheels are arranged side by side; the driving wheels are arranged on the upper sides of the driven wheels, and the driving wheels and the driven wheels are arranged in a staggered mode; through holes for allowing a casting rod to pass therethrough are formed in the end surfaces of the two sides of the machine box, and the driving wheels make contact with the driven wheels; and the driving wheels are driven by a motor; and milling cutters are mounted at the through holes where the casting rod is discharged from the machine box. The straightening machine has the effect that he casting rod can be straightened, and the straight degree of the casting rod is increased, so that when the casting rod is continuously extruded, as-cast grains in the casting rod are convenient to crush and disperse.

Description

technical field [0001] The invention relates to the technical field of cable production and processing, in particular to a straightening machine and a copper-chromium-zirconium alloy contact wire production process. Background technique [0002] With the rapid development of electrified railways, the requirements for catenary wire are getting higher and higher. It is required that the catenary wire has high strength and high conductivity at the same time. The high strength of the wire can increase the safety and stability of the train operation, and the high conductivity can save the loss of electric energy during transmission. At present, the contact wires used in electrified railway catenary mainly include four materials: pure copper, copper-silver alloy, copper-magnesium alloy, and copper-tin alloy. Among them, the conductivity of pure copper contact wire and copper-silver alloy contact wire is 97%IACS, and the tensile strength range is 350-380MPa, which are mostly used...
