Embodiment 1

[0043] A method for manufacturing a bead wire, comprising the following steps:

[0044] Step 1. Laying out

[0045] Check the steel number and specification of the incoming material; push the pre-prepared semi-finished wheel into the pay-off machine, press the "jacking" button to push the thimble into the driving hole in the center of the wheel; the wheel runs normally on the line; pull it out manually when there are 30 meters left at the bottom, Carry out manual welding in advance.

[0046] Step 2: Soldering

[0047] Turn on the power and turn on the switch of the butt welding machine; use the pedal to fix the two ends of the steel wire on the crimping clamps respectively, so that the two ends of the steel wire are aligned at the same length; adjust the current knob of the butt welding machine, press the butt welding switch, and then adjust the current to the steel wire Temper; grind the wire with an abrasive wheel grinder to make it smooth.

Abstract

The invention discloses a manufacturing method for a tire bead steel wire. The manufacturing method for the tire bead steel wire comprises the following steps of unwinding, welding, hot water washing, steel wire combing, annealing, water bath quenching, first surface treating, washing, second surface treating, washing, neutralizing, blow-drying and winding. The manufacturing method for the tire bead steel wire has the beneficial effects that the stress of the tire bead steel wire in the production process is eliminated, and residual twist of the finished tire bead steel wire is less than 0.5 turn when the finished tire bead steel wire is pulled to 9m long; the five-stage tempering design is conducted, layout design for the furnace temperature is from low to high and then back to low, heat-insulating section tempering is added based on the fact that past four section can temper, time for the steel wire in the furnace is longer, and eliminating treating for the steel wire stress is finished in a short period of time; and the steel wire quality is improved greatly, and economic benefit is achieved significantly; and through successful development and industrialization of the technology, the tire bead steel wire performance is improved, and market supplying of the tire bead steel wire is increased.

Description

technical field [0001] The invention relates to a method for manufacturing a steel wire, in particular to a method for manufacturing a bead wire. Background technique [0002] The bead wire is used in the bead part of the tire and is one of the main skeleton materials of the tire. It is used to manufacture the tire bead wire bundles of passenger cars and other vehicles. Its function is to make the tire tightly fixed on the rim, and Bear various interaction forces between tire and rim. [0003] The internal pressure and additional stress under the load of the radial tire bead are greater than that of the bias tire, so the radial tire bead should have a much larger support stiffness than the bias tire bead, and the bead process requirements in the tire production process Also stricter. The production of radial tire traveler usually adopts single steel wire winding. During production, a steel wire is wound repeatedly on the coiled disk to form a traveler with a regular hexago...
