Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coiled wire cutting device for cutting a wire that is still wound in a coil.

[0002]

2. Description of the Related Art Conventionally, when cutting a wire wound in a coil, the wire is generally cut according to the following procedure. For example, the coiled wire is suspended by the hook portion of a hanger having a C-shaped hook, and the hanger with the coiled wire suspended is conveyed to a predetermined position by, for example, a self-propelled trolley and automatically stopped. . Therefore, when cutting both ends of the coiled wire rod in the stopped state, first, the work end work for manually identifying the cut portion is performed manually. When the end of the work is cut out and the cut portion is specified, the wire cutter is manually cut using a rod cutter suspended by a balancer or the like, and the residual material after cutting is collected.

[0003]

As described above, in the conventional cutting work of the coiled wire rod, at least one person is required for the end work of the wire rod and one is required for the cutting work when cutting the wire rod.
It requires a lot of manpower, such as one person to handle the remaining material, and a total of six workers to cut both ends of the coiled wire at the same time. Since the position of the cutter blade with respect to the wire is not accurate, the cutter blade does not contact the wire perpendicularly,
As a result, there have been inconveniences such as damage to the blade of the cutter blade and scattering of the residual material at the moment when it is cut off, requiring special attention to ensure work safety.

Therefore, according to the present invention, the cutting work of the coil-shaped wire rod can be performed as mechanically as possible and the remote operation can be performed. When the wire rod is cut, the vicinity of the cut portion of the wire rod is accurately fixed to prevent the blade portion of the cutter blade from being damaged. We made sure that the cut surface of the wire was made uniform and the cut surface of the wire material was held even after the cut material was cut off to prevent the scattering of the scrap material, so that the cutting work can be performed safely. An object of the present invention is to provide a coiled wire cutting device.

[0005]

In order to achieve the above-mentioned object, a cutting device for a coiled wire according to the present invention comprises a turning base frame which turns about a turning shaft rotatably supported by a cutting device body. , So that the turning radius of the turning base frame can be changed according to the coil radius of the wire to be cut,

Further, the coiled wire cutting device of the present invention includes a hook for suspending the coiled wire in a coiled state in cutting the coiled wire, a self-propelled trolley for moving the hook, and a self-propelled trolley. And a coiled wire rod positioning control device for positioning the coiled wire rod so that the end surface of the coil of the coiled wire rod faces the swivel surface of the swivel base frame.

According to the above-described coiled wire cutting device of the present invention, when the coiled wire is cut, the expansion motor is expanded / contracted so that the turning radius of the turning base frame about the turning axis of the wire to be cut is The radius is adjusted to be the closest to the coil radius. Then, the orientation of the rod cutter around the turning axis is aligned with the orientation of the coil cutting portion around the center of the end surface of the coil of the coiled wire placed in a state of facing the turning surface of the turning base frame. Then, the swivel base frame is swiveled around the swivel axis and positioned. Prior to the operation of the cutter blade of the rod cutter, the swivel base frame approaches the wire rod so that the portions near both sides of the cut portion of the wire rod are captured in the V-shaped groove of the V-shaped receiving plate arranged on the swivel base frame. To be done. When the wire rod is captured in the V-shaped groove of the V-shaped receiver, the swing clamp operates and the wire rod is fixed in the V-shaped groove of the V-shaped receiver and stabilized. In this state, the rod cutter operates and the cutter blade cuts the wire. At that time, since the residual material is secured by being pressed into the V-shaped groove of the V-shaped receiving plate by the swing clamp, it is not scattered by impact (claim 1). Further, according to the coiled wire cutting device of the present invention, when the cutter blade of the rod cutter on the swivel base frame is brought close to the cutting portion of the wire, the cutting device body moves forward to move the swivel base frame. When the swivel surface is moved forward and the cutting of the wire rod by the cutter blade is completed, the cutting device body can be moved backward to retract the swivel surface of the swivel base frame, and the cutter blade can be aligned with the cutting portion of the wire rod. It is performed quickly and smoothly, and when the wire rod is moved after the wire rod is cut, the portion on the cutting device side such as the swivel base frame does not hinder the movement of the wire rod (claim 2). Further, according to the coiled wire cutting device of the present invention, all the operations of the coiled wire cutting device are remotely controlled, and work safety is ensured (claim 3).
