Description

[Detailed Description of the Invention] The present invention relates to a metal wire feeding device that unwinds and draws out a metal wire such as a P-C steel wire wound into a ring shape.

In general, a metal wire such as a P-C steel wire is wound into a coreless ring shape and transported, and is used by unraveling the wire, pulling out the tip, and cutting it to an appropriate length.

Conventionally, when drawing out the tip, a ring-shaped metal wire is supported on a rotating cylinder or placed on a rotating stand and the end is pulled out, but when a rotating cylinder is used, the drawing direction is unidirectional. In addition to being limited, loading the metal wire is troublesome.

Furthermore, when using a rotating stand, the ring state of the conventional ring may be distorted, and the wire may become twisted or tangled when being pulled out.

Therefore, the present invention provides a metal wire feeding device that uses a rotating stand and can be drawn out smoothly in any direction without becoming tangled or twisted. A rotatable pedestal on which a metal wire wound in a ring shape can be placed, a support shaft protruding from the center of the mount, and a horizontally extending arm that can freely rotate around the support shaft. The metal wire supply device includes a wire rod supported by the support shaft, and a wire lead-out tube through which the metal wire can be freely inserted at the tip of the arm, which is rotatable with respect to the arm.

Next, an example of implementation of the present invention will be described with reference to the drawings.

1 in the figure is a base that is installed on the floor or the like.

A support shaft 2 is rotatably protruded from the center of the base 1.

A pedestal 3 is supported on the support shaft 2 so as to be rotatable about the support shaft 2.

This mount 3 has a frame 4 assembled in a cross-shaped structure, and a bearing cylindrical body 5 fixed to the center thereof, and the cylindrical body 5 is fitted onto a support shaft 2 so as to be rotatable.

Further, a height-adjustable upright member 6 is provided at the outer end of the frame 4 to protrude upward, and a protrusion prevention piece 7 is attached to the upper end of the upright member 6 in a horizontal direction.

This extrusion prevention piece 7.7 is formed into a rod shape and is inserted into a mounting tube 8 fixed to the upper end of the upright member 6 and fixed with a lock screw 9, and is directed toward the center of the pedestal 3. The length of the protrusion can be adjusted.

An arm 10 is fixed to the upper end of the support shaft 2 in a horizontal direction.

At the tip of this arm 10 is a wire rod lead-out tube 1 whose both ends are trumpet-shaped.
1 is installed.

This wire rod lead-out tube 11 is attached to the arm 10 in a T-shape, and the attachment part 10 protruding from the outer circumferential surface is attached to the arm 10.
A is attached to the tip of the arm 10 so that it can rotate freely and cannot be removed.

The metal wire supply device configured in this manner feeds the metal wire A wound in a ring shape onto the frame 4 with the spring-out prevention piece 7 of the pedestal 3 pulled out outward, and the metal wire A wound around the support shaft 2. The base end is fixed with a steel wire termination stopper 12, and the tip is inserted into the wire rod lead-out tube 11 and pulled out.
The mount 3 rotates together with the arm 10 to face the direction in which the wire rod A is pulled out, and further, the gantry 3 rotates and is sequentially pulled out while the direction of the wire rod lead-out tube 11 is maintained by the pull-out force.

Further, when the drawing direction of the wire rod A is changed, the direction of the wire rod lead-out tube 11 is automatically changed accordingly, and the wire rod drawing tube 11 can freely follow the drawing in any direction.

The metal wire feeding device of the present invention is configured as described above, and includes a rotatable mount on a base, and a rotatable support shaft at the center of the mount, and the direction of the support shaft can be changed via an arm. By providing a wire rod lead-out tube, the direction of the wire rod lead-out tube can be freely followed in any drawing direction.
In addition, the mount rotates due to the pulling force, and the wire is pulled out from the circumference of the ring-shaped wire while maintaining an angle close to the tangent to the ring, so that the wire does not twist or become tangled when being pulled out. , the wire can be pulled out smoothly.
