Wirecord fabric heat hob cutting device and method thereof

Abstract

The invention relates to a crop device and method of the wire-cord fabric hot hob, in which the technical scheme of hot hob crop is adopted. Through the heat of the cutter body, the sizing compound is separated. Moreover in the crop process of the cutter body, the body rolls along the axial direction of the wire. Between the cutter body of the hot hob and the fixed axis, a small gap is arranged so that the cutter body can be in the left and right movement along the fixed axis. Thus the tilting and bending issue of wires targeted is resolved. With the adoption of the hot hob and the method, the sizing compound is separated through the heat of the body to complete the crop of the wire-cord fabric. The cross section of the cropped sizing compound is smoother, which is more in line with the cord-processing requirement of the follow up tire ply forming process. Moreover, through the hot hob crop device in which the body can be in self-adaptive adjustment along the fixed axis, when the tilting or bending is occurred on the steel wire, the cutter body can be in rolling crop along the axial direction of the steel wire.

Description

technical field [0001] The invention relates to a cutting device for processing rubber tires and a cutting method thereof, in particular a hot hob device is used to cut steel cords, which belongs to the field of mechanical manufacturing. Background technique [0002] Tires are the main action components of motor vehicles. Whether the tire processing quality can meet the design requirements will directly determine the safety performance of motor vehicles. The steel cord fabric used in rubber tire processing is composed of steel wire and rubber covering the steel wire. Steel wires are evenly arranged in the rubber compound, and form an angle of 90° with the cord winding direction, and each strand of steel wire is composed of several thin steel wires. [0003] The existing steel cord cutting process usually uses a cold knife to cut the cord, that is, the cord is cut through a simple physical extrusion process, but it often results in an arc-shaped cutting effect of the rubber ...

AI Technical Summary

Problems solved by technology

[0003] The existing steel cord cutting process usually uses a cold knife to cut the cord, that is, the cord is cut through a simple physical extrusion process, but it often results in an arc-shaped cutting effect of the rubber material section, which will be unfavorable to the quality of the subsequent butt joint seam Affected, so it is a substandard cut product in the process

[0004] Moreover, usually as shown in Figure 3 below, due to the reason of the previous processing procedure or the process of correcting the deviation when feeding the material, the steel wire in the cord will eventually be inclined or bent.

Although this inclination or bending is not a drastic change, it still has a greater impact on the cutting process

[0005] In the process of cutting with a cold knife, the knife body runs perpendicular to the feeding direction of the cord. If the above problems occur, the knife body will inevitably touch the steel wire, which will directly cut through the rubber material to expose the steel wire, or directly climb over the steel wire and When it comes to the phenomenon of continuous cutting between the other two steel wires, the above situation is not allowed by the steel cord cutting process.
