Abstract

PROBLEM TO BE SOLVED: To provide a machining method for a long wire in which environmental problems are not generated, and moreover, mechanical properties of the long wire are not degraded, and which is compatible with the in-line. SOLUTION: The oxide scales and deposits of the long wire W are removed by passing the long wire W between a plurality of lateral rolls 31 which are pivotally supported extending in the horizontal direction and whose heights are different in a zigzag shape and/or a plurality of longitudinal rolls which are rotatably supported extending in the vertical direction and whose positions are different in a zigzag shape and by bending the long wire W in the vertical direction and/or in the horizontal direction. The long wire W, in which the oxide scales or the like are removed, is passed in a state that the long wire is clamped by two or more of elastic rollers with required force, and the elastic rollers are rotated in the same direction as the passing direction of the long wire W or in the opposite direction so as to make a peripheral speed faster or slower than the passing speed of the long wire W. The long wire W is rubbed by throwing a powdery particulate grinding material into a space between the elastic rollers.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a long wire and an apparatus therefor, and more specifically, to roughening the surface of the long wire whose cross-sectional shape is circular, roughly circular, polygonal or irregular. , Oxide scale removal, rust removal, foreign matter removal,
The present invention relates to a method and an apparatus suitable for performing processing such as.

[0002]

2. Description of the Related Art When the above-mentioned long wire is processed by using a cutting tool, a grinding wheel, a brush, a belt sander, etc., particularly when the long wire has a small cross section, It is extremely difficult to process the outer circumference continuously and uniformly. Therefore, conventionally, in the case of removing oxide scale such as a long wire and rust, a pickling method, a peeling method, a peeling method using a die, or the like (see, for example, 2857279) is also used to remove adhered substances. In this case, a pickling method, an alkali cleaning method, an organic solvent cleaning method, etc. are used.

[0003]

However, in the pickling method,
Since a large amount of water is used, the cost of wastewater treatment and environmental measures becomes high, and the equipment becomes large-scale. Moreover, when processing thin long wires, etc. Since it is difficult to uniformly soak the acid in the pickling solution, uneven treatment occurs, and when the long wire is iron-based, its mechanical properties deteriorate depending on the acid (chemical) used. There was such a problem. In addition, in the pickling method, since the equipment is large-scale as described above, if the operation is temporarily stopped during the operation of the treatment, the long wire is excessively immersed in the acid and the surface thereof is significantly deteriorated. Therefore, it has been difficult to put the processing device in-line by the pickling method.

Further, in the peeling method for removing foreign matters and the like by passing a long wire between cutting tools such as composite cutting tools or dies,
There are adverse effects such as cutting traces remaining on the long wire and cutting of the long wire due to tension applied by cutting resistance. Also, in the alkaline cleaning method and the organic solvent cleaning method, the liquid used is a chemical as in the pickling method, so management is very difficult in terms of protection of the working environment, and since it is a wet method, the apparatus becomes large. There was a problem of doing.

The present invention has been made in view of the above circumstances, and its purpose is to prevent environmental problems.
Moreover, it is an object of the present invention to provide a method for processing a long wire and an apparatus for the same which can be in-lined without deteriorating mechanical properties of the long wire.

[0006]

In order to achieve the above object, a method for processing a long wire in the present invention is a method for processing a long wire by passing through various processing means, and is Between a plurality of lateral rolls that extend and are pivotally supported and have different heights in a staggered manner, and / or a plurality of vertically oriented rolls that extend in a vertical direction and that are horizontally staggered in a staggered manner. Passing through the long wire, bending the long wire in the vertical direction and / or the horizontal direction, and removing oxide scale and deposits on the long wire; The scale line is passed while being sandwiched by two or more elastic rollers with a force of a required magnitude, and the peripheral speed is made faster or slower than the passage speed of the long line. Forward in the same direction as the passing direction or in the opposite direction It is characterized by including the step of rotating the elastic roller and the step of rubbing the long wire by introducing a powdery or granular abrasive between the elastic rollers.

Here, the elastic roller used in the present invention has elasticity so that it can hold the abrasive material with the long wire and can withstand the frictional force generated when passing the long wire. Any size, shape, and material can be used as long as it has sufficient strength and can be rotated by an electric motor.

In the present invention, the magnitude of the force that the two or more elastic rollers sandwich the long line is such that the elastic roller that sandwiches the long line can rotate with respect to the long line with the abrasive interposed. It is something. Further, while the elastic roller is rotated while allowing the peripheral speed of the elastic roller to pass through the elongated line so as to be faster or slower than the passing speed of the elongated line, the abrasive is made into the elongated line. The long wire is processed by relatively moving it and rubbing the long wire.

The soft abrasive used in the present invention is a single plant or a mixture of plants having grindability such as rice husks, mulberry leaves, and tree bandits. These abrasives are suitable for so-called mild surface finishing and removal of deposits on the surface of long lines.

The hard abrasive used in the present invention is ceramics, glass powder, non-ferrous metal powder, metal powder or the like, or a mixture thereof. These abrasives are suitable for strong processing such as long scale oxide scale removal, rust removal, foreign material removal, deburring, and rounding.

The mixture of soft and hard materials used in the present invention is a grindable plant such as rice husk, mulberry leaf, and wood bandage, ceramics, glass powder, non-ferrous metal powder, metal powder, etc. And a mixture of these. These abrasives are suitable for lightly grinding or polishing the surface of a long wire.

The size of the abrasive used in the present invention is determined by the correlation with the cross-sectional dimension of the long wire, etc., but when the particle size is 0.02 to 2.50 mm. It is easy to supply to the container and is excellent in removing foreign matter on the surface of the long wire. Further, by humidifying the elastic roller, the processing function can be enhanced.

The long wire in the present invention means a long wire having a circular cross section, a substantially circular shape, a polygonal shape, an irregular shape, etc., and its material is not limited.

In the present invention, basically, the long wire is pressed and gripped from two opposite directions, but it may be pressed and gripped from three directions. Further, if it is expected that substantially uniform processing is performed but it is not sufficient, the processing may be performed again at a position where the pressing position is displaced by a required angle around the long line.
