Description

TECHNICAL FIELD The present invention relates to a machine for winding a hot-rolled wire into a coil.

[Prior Art and its Problems] As a machine for winding a hot-rolled wire at a high temperature extracted from a rolling mill or a heat treatment furnace into a coil, a machine having a complicated structure as shown in FIG. 3 is conventionally known. Has been. The structure of this machine will be briefly described. A base a is installed on a floor, a hollow rotating shaft b is vertically supported by bearings c of the base a, and the rotating shaft b is supported on the rotating shaft. A rotary table d is provided, a cylindrical outer drum e is provided on the rotary table d, and a rotary shaft b is connected by bevel gears g so as to be rotated by a motor f. Is provided with an elevating disk h fixed to the upper end of the center axis i, the center axis i is inserted into a rotating shaft b, and the lower end thereof is rotatably supported by a thrust bearing j, and the bearing j is connected via a link k. An L-shaped connecting rod l is connected to one end, the connecting rod l is supported by a bearing m, and the other end is connected to a cylinder n. When the cylinder n is actuated, the central axis i moves up and down, and the elevating disk h moves up and down. It is about to do. In addition, o is a core member pivotally supported by a pin p in the turntable d, and the core member o can be tilted by a cylinder q on the base a. In the winding machine configured as described above, the wire rod is wound onto the outside of the core member o on the elevating disk h by driving the motor f, and when the winding of a certain amount is completed, the motor f is wound.
Is stopped and the cylinder n is operated to raise the elevating disk h, so that the wire coil can be taken out onto the outer drum e. In this winding machine, however, an elevating disk h is provided for facilitating the take-out of the above wire coil. Therefore, the central axis i must be hung deep underground and the cylinder n must be installed underground. Not only is it mechanically complicated, but there is a drawback that equipment costs are involved, and the wire coil must be sandwiched and supported by some means in order to transport the taken out wire coil to the next step. There were drawbacks such as easy attachment.

[Means for Solving the Problems] The winding machine of the present invention is intended to solve the above-mentioned drawbacks by providing a mooring portion on a narrow end of a tapered winding core and a flange portion on a large diameter portion. Swift, a turntable that supports the flange portion of the swift so that the winding core is in a vertical state, a clamp that detachably fixes the swift on the turntable, and the turntable is rotated in a horizontal plane. It consists of a motor and a cylindrical outer drum that is formed on the outer peripheral edge of the turntable so as to surround the circumference of the swift with a winding space for the wire rod. The swift wound with the wire rod is suspended at the mooring portion. It is characterized by being configured so that it can be lowered and hung from the turntable.

[Operation] Since the wire rod is wound around the Swift and the Swift can be freely attached and detached from the turntable, the transfer work becomes easy.

[Embodiment] Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. In this winding machine, a shallow pit 1 is dug on the floor, a base 2 is fixedly mounted on the shallow pit 1, bearings 3 and 4 are provided at the upper and lower parts of the center of the base 2, and a rotary shaft 5 is attached to the bearings 3 and 4. Support it so that it will be vertical. 6 is a motor horizontally placed on the floor, 7 is a bearing for supporting a rotary shaft 8 of the motor, 9 is a bevel gear fixed to the tip of the rotary shaft 8, and the bevel gear 9 is the rotary shaft 5 Meshes with a bevel gear 10 fixed to the outer periphery of the. An annular lift frame 11 having a flat upper surface is provided on the outer periphery of the upper portion of the base 2 so as to be vertically movable by the operation of the cylinder 12. A turntable 13 is fixed to the upper part of the rotary shaft 5, and a clamp mechanism described below is provided on the turntable 13. That is, a support shaft 14 is provided at the bottom of the turntable 13, and an L-shaped clamp 15 is pivotally supported on the support shaft 14, and the upper end of the clamp 15 is projected from the upper surface of the turntable 13 and the other end of the turntable 13 is supported. The trochanter 16 is provided so as to project from the outer peripheral surface, and the trochanter 16 is slidably brought into contact with the upper surface of the elevating frame 11.
Reference numeral 17 denotes a spring box provided on the lower side of the outer peripheral edge of the turntable 13, and its working rod presses down on the trochanter 16 of the clamp 15. A cylindrical outer drum 18 having substantially the same diameter as that of the turntable 13 is fixed to the outer peripheral edge of the turntable 13. The numeral 20 is a swift that is detachably supported on the turntable 13. The swift 20 has a disc-shaped flange portion 20a.
A winding core 20b is formed in the center of the upper surface of the winding taper and has a cross-section of 10 and is tapered upward, and a mooring portion 20c formed of a through hole is formed at an upper end of the winding core 20b. A water cylinder-shaped footrest 20d is formed below the flange portion 20a.

However, the lever Swift 20 is hung on a crane rope and carried onto the turntable 13. At that time, the cylinder 12 is contracted and the clamp 15 is tilted outward at the center of the foot 20d of the Swift 20 by the elasticity of the spring. Thus, the swift 20 is fixedly fixed on the turntable 13. The rotary shaft 5 and the turntable 13 are driven by the rotation of the motor 6.
The hot-rolled wire rod 21 heated to 800 ° or more by being rotated is wound around the flange portion 20a of the swift 20. In this case, the motor 6 is designed so that its rotation speed is perfectly synchronized with the wire rod entry speed so that no extra tension is applied to the wound wire rod.

The wire rod wound around the swift 20 in this manner can be lifted by the crane rope together with the swift by operating the cylinder 12 and loosening the clamp 15. If necessary, the suspended wire rod can be directly loaded into an annealing pot or a heat treatment furnace (not shown).

[Advantages of the Invention] As described above with reference to the embodiments, the hot-rolling wire winding machine according to the present invention can wind the wire together with the swift by winding the wire around the swift, and thus the wire may be flawed. In addition, there are various advantages such as easy transfer work, and a significantly lower cost because the equipment does not require a disk lifting mechanism.
