Problems solved by technology

[0004] However, the effect of physical rust removal in the above-mentioned methods does not reach the claimed purpose of completely replacing pickling and rust removal, and cannot completely remove the oxide layer on the surface of the steel wire. Proper pickling is required to remove the remaining oxide layer, and the complete removal of the

Example Embodiment

[0041] Example 1

[0042] Such as Figure 1-5 As shown, a steel wire batch physical rust removal device includes a vertical shelling wheel 1, a horizontal shelling wheel 2, a spiral wire brush 3, and a rust removing machine 4.

[0043] The vertical shelling wheel 1 includes a first roller 1.1 and a second roller 1.2 vertically arranged. The first roller 1.1 is located above the second roller 1.2, but the highest point of the groove of the second roller 1.2 is located at the first roller. Between the highest point and the lowest point of the wheel groove of the roller 1.1, so that when the steel wire 5 passes through the lowest point of the wheel groove of the first roller 1.1 and the wheel groove at the highest point of the second roller 1.2, the wire Deformation, bending and peeling of the oxide scale on the lower surface.

[0044] The horizontal shelling wheel 2 is horizontally arranged on the right side of the second roller 1.2, the spiral wire brush 3 and the rust remover 4 are...

Example Embodiment

[0047] Example 2

[0048] A steel wire batch physical derusting device, same as Example 1, the difference is: the vertical shelling wheel 1 and the horizontal shelling wheel 2 are all made of YG8 hard alloy steel with a diameter of 125mm and a groove depth 15mm. The spiral rod 3.1 is made of 65# steel, the derusting wire 3.2 is made of 80# steel with a diameter of 0.2 mm and a length of 10 cm, and the diameter of the spiral rod 3.1 is 8 cm. The length of the spiral wire brush is 150mm, and the pitch is 30mm. The roll wire 4.2 is made of steel wire with a diameter of 0.3 mm and a length of 0.2 mm.

Example Embodiment

[0049] Experimental example 1

[0050] A steel wire batch physical rust removal device, the same as the embodiment 2, the difference is that the spiral wire brush 3 is not included in the device.

[0051] Test 1: Test the rust removal effect of the devices of Example 2 and Experimental Example 1 using steel wires produced in the same batch and under the same conditions. The results show that there is a large amount of oxide scale under the spiral wire brush 3, However, there is no obvious oxide scale under the steel wire without the spiral wire brush 3. This is mainly because the spiral wire brush 3 designed in the present invention can compress a certain distance along the moving direction of the steel wire under the action of the steel wire, so that the rust removal wire will be The holding force between the steel wire and the steel wire is always automatically adjusted to a state suitable for steel wire rust removal, which maximizes the effect of steel wire rust removal.

Abstract

The invention relates to a steel wire batched physical rust removal device, and belongs to the technical field of steel wire surface treatment. The device comprises a vertical shelling wheel, a transverse shelling, a spiral steel wire brush and a rust removal machine; the vertical shelling wheel comprises a first rolling wheel and a second rolling wheel which are arranged vertically, the first rolling wheel is located on the upper portion of the second rolling wheel, and the highest point location of a wheel groove of the second rolling wheel is located between the highest point location and the lowest point location of the first rolling wheel; the transverse shelling wheel is horizontally arranged on the right side of the second rolling wheel, the spiral steel wire brush and the rust removal machine are sequentially arranged on the left side of the vertical shelling wheel, a steel wire passes through the wheel groove at the lowest point of the wheel groove of the second rolling wheeland then continues to drive forwards by surrounding the transverse shelling wheel; the spiral steel brush is composed of a spiral rod and a rust removal wire, and one end of the rust removal wire is fixedly arranged on the inner surface of the spiral rod. The steel wire batched rust removal device and process can achieve the pickling effect, and chemical pickling rust removal can be completely replaced.

Description

technical field [0001] The invention relates to the technical field of steel wire surface treatment, in particular to a device and process for batch derusting steel wire for tires that can completely replace pickling. Background technique [0002] Tire wire refers to the steel wire inlaid on the edge of the rubber tire, also known as bead wire or tire edge wire. The steel wire used to make tires is generally made by cold-drawing the steel wire with a hot-rolled wire rod. During the hot-rolling process of the wire rod, the steel wire reacts with oxygen to form a layer of hot-rolled scale on the surface of the steel wire. At the same time, due to the After being stored for a long time, rust oxidation film and oxidation spots will also be formed on the surface after being oxidized by water. The tire steel wire not only needs to have high tensile strength, toughness and good fatigue resistance, but also should have good bonding ability with rubber; It will have an adverse effe...
