Special metal wire twisting machine

Abstract

The invention relates to a special metal wire twisting machine which mainly consists of a core wire and a surface wire pay-off rack, a core wire cradle K30, a core wire transmission assembly, a core wire tension and bridge assembly, a surface wire cradle K90, a surface wire transmission assembly, an over-twisting mechanism, a speed reducer, a speedometer, a traction mechanism, a meter counter, a straightening device, a wire arranging and take-up mechanism, a main motor and an electric control cabinet. The twisting mechanism has a compact structure, causes low noise, is stable in operation, is convenient to install and maintain, ensures table product quality, and can produce cores of 3+9*0.175, 3+9*0.22 and 3+8*0.22HTHC.

Description

technical field [0001] The invention relates to a twisting device for twisting cord strands, which is a special wire twisting machine for producing steel cords for light truck tires, semi-finished cords for truck tires and high-strength cords. Background technique [0002] Existing metal wire twisting equipment with 3+9×0.175, 3+9×0.22, 3+8×0.22HT HC structures are not only imported, but domestically manufactured equipment has the following disadvantages: 1. Core wire and upper wire are separated 2. The flywheel slider installed on the steel flywheel disc, the metal wire moves up and down, and it is easy to get out of the slider. Flying out; 3. There is no speedometer or the motor does not have an encoder, which causes the core wire pay-off and the upper thread pay-off to be out of sync; 4. The take-up and arranging wires are arranged by a screw rod, and the adjustment of the wire width and tension is inconvenient. Interchangeability is poor. Contents of the invention ...
