Embodiment 1

[0030] Embodiment 1: a kind of production method of uncoated metal wire rod, comprises the following steps:

[0031] Step 1: Material selection: According to the user's technical requirements for uncoated steel wire, select φ5.5mm wire rod with qualified surface quality and 0.82%C, 0.50%Mn, 0.17%Si, 0.01%P, 0.002%S content;

[0032] Step 2: Pretreatment: The selected φ5.5mm wire rod is pretreated, followed by mechanical peeling, pickling, water rinsing, boron coating, and drying processes, and then the φ5.5mm wire rod is wound on a φ1250 I-shaped wheel;

[0033] Step 3: Rough drawing: use a dry drawing machine to draw the pretreated φ5.5mm wire rod to a φ1.42mm semi-finished steel wire; the number of drawing passes is 13, and the drawing speed is 8m / s;

[0034] Step 4: Heat treatment: The φ1.42mm semi-finished steel wire obtained in step 3 is degreased to remove residual impurities on the surface, and then enters an open flame furnace for austenitization treatment. The treatm...

Embodiment 2

[0039] Embodiment 2: a kind of production method of uncoated metal wire rod, comprises the following steps:

[0040] Step 1: Material selection: According to the user's technical requirements for uncoated steel wire, select φ5.5mm wire rod with qualified surface quality and 0.72%C, 0.50%Mn, 0.15%Si, 0.008%P, 0.003%S content;

[0041] Step 2: Pretreatment: The selected φ5.5mm wire rod is pretreated, followed by mechanical peeling, pickling, water rinsing, boron coating, and drying processes, and then the φ5.5mm wire rod is wound on a φ1250 I-shaped wheel;

[0042] Step 3: Rough drawing: use a dry drawing machine to draw the pretreated φ5.5mm wire rod to a φ2.20mm semi-finished steel wire; 8 drawing passes, drawing speed 8m / s;

[0043] Step 4: Heat treatment: The φ2.20mm semi-finished steel wire obtained in step 3 is degreased to remove residual impurities on the surface, and then enters an open flame furnace for austenitization treatment. The treatment temperatures in the five...

Abstract

The invention relates to a production method and device for plating-free metal wires, and the production device comprises a pickling tank and a rinsing tank, the bottoms of the pickling tank and the rinsing tank are respectively provided with a drain pipe with a valve, rotating shafts are vertically arranged in the pickling tank, and the lower ends of the rotating shafts are fixedly provided withfirst rotating discs. The bottoms of the first rotating discs are fixedly connected with one ends of a plurality of first deflector rods. The first deflector rods are all obliquely arranged at uniformintervals, two transverse roll shafts are arranged in the pickling tank, and spiral grooves are formed in the peripheries of the roll shafts. According to the production device, multiple sets of rotating shaft and wire guide wheel structures can be arranged in the pickling tank and the rinsing tank, and transmission wheels are arranged on the peripheries of the rotating shafts and connected through transmission chains or transmission belts, so that the multiple steel wires can be pickled at the same time; and the steel wires are bent in the pickling tank and the rinsing tank, so that the steel wires can be pickled in a smaller space, the occupied area of the pickling tank and the rinsing tank can be reduced, and the occupied area of a production line can be reduced.

Description

technical field [0001] The invention belongs to the field of metal processing, in particular to a production method and device of an uncoated metal wire. Background technique [0002] There are many types of metal wires that we come into contact with daily, such as bead wires, steel cords, hose wires, etc. Whether it is bead wire, steel cord, or hose wire, there is a layer of metal coating on the surface, which we call coated steel wire. The coating on the surface of the steel wire has the following functions: ① prevent the surface of the steel wire from being corroded; ② increase the bonding performance between the steel wire matrix and the rubber; ③ provide an effective lubricating layer for the drawing process. [0003] Coated steel wire has limited its application in some aspects due to the existence of surface coating. Such as shot blasting steel wire, because the steel wire needs to act on other objects, in order to prevent impurity pollution to the acting object, it...
