Abstract

The invention discloses a cable sheath outer diameter adjusting method. The method includes steps: acquiring a sheath inner diameter R3, and setting a target sheath outer diameter R2; measuring a current sheath outer diameter R1; calculating a target screw rotation speed and controlling a screw to rotate at the target screw rotation speed, or calculating a target cable moving speed and controlling a cable to move at the target cable moving speed, wherein N0 refers to a current screw rotation speed, and V0 refers to a current cable moving speed. According to the method, by accurate correction of the screw rotation speed or the cable moving speed, sheath outer diameter offset can be effectively eliminated, large sheath outer diameter offset is avoided, and accordingly the problem of difficulty in control of cable sheath outer diameter uniformity can be effective solved. The invention further discloses a cable sheath outer diameter adjusting system adopting the cable sheath outer diameter adjusting method.

Description

technical field [0001] The present invention relates to the technical field of cable manufacturing, more specifically, to a method for adjusting the outer diameter of a cable sheath, and a system for adjusting the outer diameter of a cable sheath adopting the method. Background technique [0002] During the extrusion process of the sheath of the cable, the cable core generally passes through the extruder, and the extruder extrudes the sheath on the cable core. After the extruded sheath enters the water tank, it is quickly cooled and shaped. Among them, the extruder generally has a screw that rotates quickly to extrude the fluid material into the mold sleeve, and under the limit of the inner hole of the mold sleeve, the material is evenly surrounded on the outside of the cable core. [0003] However, after long-term research by the inventor, it has been found that the outer diameter of the sheath coming out of the mold sleeve will undergo a certain expansion, and there are m...
