Abstract

The invention discloses a wire penetrating guide wheel of a wire twisting machine and the wire twisting machine. The wire penetrating guide wheel comprises a wheel body, the wheel body comprises a wheel disc and a penetrating shaft hole located in the center of the wheel disc, the wheel disc comprises an annular wheel surface and a circular wheel ring arranged at the periphery of the wheel surface, and the wheel surface and the wheel ring are integrally connected; the surface of the wheel ring is concaved downwards to form a V-shaped wire slot, the bottom surface of the V-shaped wire slot is a plane or a concave surface, the width of the bottom surface of the V-shaped wire slot is 2-4 mm, and the included angle of the V-shaped wire slot is an acute angle; and the surface of the V-shaped wire slot is provided with a ceramic layer. According to the wire penetrating guide wheel, the R angle of the bottom of the V-shaped wire slot is increased, deformation of a finished twisted wire product can be avoided, the qualified product rate is increased, and meanwhile the twisted wire product specification can be enlarged; and the wheel body is made of 40Cr steel, due to the fact that the 40Cr steel has the high hardness and is not likely to soften a surface coating, the service life is prolonged, and due to the fact that the thermal expansion coefficient of the 40Cr steel is almost same as that of a bearing, the phenomenon that the outer ring of the bearing slips is not prone to generate, and then the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to a wire passing guide wheel of a wire stranding machine and a wire stranding machine. Background technique [0002] Stranding machine is a kind of wire that can be widely used in various types of soft / hard conductor wires (copper wire, enameled wire, tinned wire, copper-clad steel, copper-clad aluminum, etc.) , PVC wire, network wire, etc.) stranding mechanical equipment, through the guide wheel to twist multiple single conductors into one strand, to meet the technical requirements of the wire. At present, the guide wheel of the stranding machine sold in the market generally has too small R angle at the bottom of the guide wheel groove, and the twisted finished wire is deformed; the material of the guide body is not high in hardness and is easy to wear; the coefficient of thermal expansion is large, and the bearing is easy to run out of the outer ring. Disadvant...
