Abstract

PURPOSE:To facilitate the transfer of a wire coil to the succeeding stage and to reduce the equipment cost by providing the swift to which a wire rod is wound freely attachably on a turntable and slinging out the wire rod wound onto the swift together with it. CONSTITUTION:When a lift frame 11 is descended by contracting the cylinder 12 located on a base stand 2 at the time when the swift 20 suspended by a rope is transferred onto a turntable 13, a clamp 15 is tilted around a bearing shaft 14 by the elasticity of a spring and the swift 20 is immovably fixed on the turntable 13 with the tilting of the clamp 15 outward in the base leg 20d of the swift 20. A wire rod 21 is now wound on the flange part 20a of the swift 20 by turning the turntable 13 with the driving of a motor 6. The wire rod 21 is slung out by a rope together with the swift 20 by relaxing the clamp 15 with the actuation of the cylinder 12 after the wire rod 21 being wound and is transported to the succeeding stage, if necessary.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a machine for winding hot rolled wire into a coil.

[Conventional technology and its problems] A machine with a complicated structure as shown in Figure 3 has been known as a machine for winding hot-rolled wire at high temperatures extracted from a rolling mill or heat treatment furnace into a coil. It is being To briefly explain the structure of this machine, a base a is installed on the floor, and a hollow rotating shaft is connected to the bearing CTC of the base a.
vertically supported by, and a rotary table d is provided on the rotation axis,
A cylindrical outer drum e is provided on the rotary table d, and the rotating shaft is connected by a bevel gear gag so as to be rotated by a motor f, and an elevating disk h fixed to the upper end of the central axis i is mounted on the rotary table d. , the central shaft i is inserted through a rotating shaft and its lower end is rotatably supported by a thrust bearing j,
The bearing j is connected to one end of an L-shaped connecting rod I through a link k, and the connecting rod 1 is supported on a bearing m, and a cylinder n is connected to the other end. The elevating disc h is adapted to move up and down. Note that 0 is a winding core member pivotally supported by a pin p in a rotary table d, and the winding core member 0 can be tilted by a cylinder q on a base a. In the winding machine configured in this manner, the wire is wound onto the outside of the winding core member 0 on the lifting disk h by the drive of the motor f.

After winding a certain amount, stop the motor f and turn the cylinder n
The wire coil can be taken out onto the outer drum e by activating the elevating disk h to raise it. However, the lever winder is equipped with an elevating disk h to facilitate the removal of the wire coil, but for this purpose, the central axis i must be suspended deep underground, and the cylinder n must be installed underground, making installation easier. However, it is not only mechanically complex, but also has the disadvantage of increasing equipment costs.In addition, the wire coil must be held and supported by some means in order to transport the wire coil to the next process. It had drawbacks such as being easy to attach.

[Means for Solving the Problems] The winding machine of the present invention is intended to solve the above-mentioned drawbacks, and has a tapered winding core with a mooring part at the narrow end and a flange part at the thick diameter part. a turntable that supports a flange portion of the Swift so that the first volume core is vertically disposed;
A clamp for removably fixing the Swift on the turntable, a motor for rotating the turntable in a horizontal plane, and a clamp for enclosing the Swift at the outer periphery of the turntable with a wire winding space in between. The present invention is characterized in that it consists of a cylindrical outer drum formed in the form of a cylindrical outer drum, and is configured such that a swift wound with a wire rod is suspended from the mooring portion so as to be freely suspended from above the turntable.

[Function] The wire is wound onto the swift, and the swift can be attached to and detached from the turntable, making the transfer operation easier.

[Embodiment] Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. This winding machine has a shallow pit 1 dug in the floor, a base 2 fixed on top of it, bearings 3 and 4 installed at the top and bottom of the center of the base 2, and a rotating shaft 5 attached to the bearings 3 and 4. Support it so that it is in a vertical position. 6 is a motor placed horizontally on the floor; 7 is a bearing that supports the rotating shaft 8 of the motor; 9 is a bevel gear fixed to the tip of the rotating shaft 8; the bevel gear 9 is connected to the rotating shaft 5; meshes with a bevel gear 10 fixed on the outer periphery of the An annular elevating frame 11 with a flat upper surface is provided on the upper outer periphery of the base 2 so as to be movable up and down by the operation of a cylinder 12. A turntable 13 is fixedly installed on the upper part of the rotating shaft 5, and the turntable is provided with a clamp mechanism described below. That is, a support shaft 14 is provided at the bottom of the turntable 13, an L-shaped clamp 15 is pivotally supported on the support shaft 14, and the upper end of the clamp 15 is made to protrude from the upper surface of the turntable 13, and the other end is attached to the turntable 13. A trochanter 16 is provided here to protrude from the outer peripheral surface of the lift frame 11.
Slideably abut on the top surface of. Reference numeral 17 denotes a spring box provided below the outer peripheral edge of the turntable 13, and its working rod presses down on the trochanter 16 of the clamp 15. The outer peripheral edge of the turntable 13 is fixed with a cylindrical outer drum 18 having approximately the same diameter as the turntable.
0 is a swift that is detachably supported on the turntable 13. The swift 20 has a disk-shaped flange portion 20.
A winding core 20b is formed at the center of the upper surface of the winding core 20b and has a cross section that is tapered upward and tapers upward, and a mooring portion 20c that is a through hole is formed at the upper end of the winding core 20b. A water surface-like footrest 20d is formed below the flange portion 20a.

However, the Swift 20 is suspended from a crane rope and carried onto the turntable 13, and at that time, the cylinder 1
2 is contracted and the clamp 15 is tilted outward in the foot 20d of the Swift 20 by the elasticity of the spring, thereby fixing the Swift 20 immovably on the turntable 13. The rotating shaft 5.
By rotating the turntable 13, the hot-rolled wire 21 heated to 800° C. or higher is wound onto the flange portion 20a of the swift 20. In this case, the rotational speed of the motor 6 is completely synchronized with the advancing speed of the wire so that no unnecessary tension is applied to the wire being wound.

The wire rod wound up in Swift 20 in this way is
2 and loosening the clamp 15, the entire Swift can be lifted out using a crane rope. The suspended wire rod can also be directly inserted into a slow cooling pot or a heat treatment furnace (not shown) if necessary.

[Effects of the Invention] As described above in the embodiments, the hot-rolled wire rod winding machine according to the present invention is capable of suspending the wire rod together with the swift by winding it around the swift, so there is no risk of the wire rod being damaged. It has various advantages, such as making the transfer work easier, and since there is no need for a mechanism for lifting and lowering the disk on the equipment, it can be manufactured at a significantly lower cost.
