Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a device for temporarily storing subsequent wire in reforming equipment after wire laying.

(Prior art) Conventional methods for heat treating wire rods after winding include continuous heat treatment on a stelmore conveyor, or cooling once after winding, and then reheating in a batch furnace or continuous furnace. This method was commonly used.

However, when heat treatment is performed on the former Stelmore conveyor, full-scale heat treatment for a long time is impossible due to the length of the conveyor. Also,
The latter method has the disadvantage that the heat held by the coil during winding is wasted because the coil is cooled once, and the heat treatment requires a long time because it is heated again from the cooled state.

Therefore, the present applicant has proposed a laying cone that is hermetically arranged on the ceiling wall of a furnace placed immediately after a finishing rolling mill, a rider holding mechanism that supports a preheated rider at a position below the laying cone, and a rider holding mechanism for supporting the preheated rider at a position below the laying cone. an elevating mechanism, a temporary holding mechanism that is interposed between the rider holding mechanism and the laying cone and temporarily supports the wire rod immediately after finish rolling that is led out from the laying cone, and a wire rod that is wound on the rider and formed into a coil. proposed a winding device for hot-rolled wire, which is equipped with rollers for conveying wire into a furnace (patent application 1983-
No. 65848), which attempted to solve the above-mentioned conventional drawbacks. In addition, this invention allows spheroidizing annealing, which conventionally required more than 10 hours, to be carried out in a few hours by heating, rolling, and winding the wire at a certain value and then immediately holding it. This was done based on the knowledge that

(Problems to be Solved by the Invention) The winding device is an excellent invention that can solve the conventional drawbacks, but the fingers of the temporary holding mechanism (hereinafter referred to as "iris") constituting the winding device are The coil is supported and released by rotating within the same plane at the position, and there is a limit to the upper limit position of the rider, so there is a considerable vertical distance between the finger position and the rider. Therefore, it has been found that there are inherent problems such as the occurrence of surface flaws due to mutual buffering due to falling between the coils and the action of impact force on the rider during delivery.

The present invention was made to solve this problem, and aims to provide a device that gives the iris a lifting function and brings the finger as close as possible to the rider during coil transfer, thereby making it possible to transfer the coil at close range. It is something to do.

(Means for solving the problem) An iris that temporarily stores the wire that is wound down from a laying cone that is hermetically arranged on the ceiling wall of the furnace, and a rider that is fed onto the hearth roller at the bottom of the furnace. In an apparatus equipped with a rider operation mechanism that receives a coil scooped up and stored by the iris and transfers it together with a rider onto a hearth roller, the iris is configured to be able to be raised and lowered separately from the raising and lowering movement of the rider operation mechanism. This is an elevating type wire storage device.

(Function) Since the elevating type wire storage device according to the present invention is configured such that the iris can be raised and lowered, it is possible to temporarily transfer or deliver the wire storage coil in a state in which it is brought close to the rider.

(Example) The drawing shows an example of the present invention.
For example, this is a heat retention furnace body, which is communicated with the heat retention furnace and the lidar preheating furnace through a gate (not shown), and a laying cone 3 is disposed in close contact with the upper opening 2 of the body. In addition, 4 is a hearth roller, and the rider 5 is transported by this.

Reference numeral 6 denotes a lidar operating mechanism, which includes a plurality of operating rods 7 that penetrate the heat retention furnace body 1, a support member 8 that is connected to the lower end of the operating rods 7 to maintain horizontality, and furthermore, although not shown, It is composed of a lifting mechanism such as a hydraulic cylinder that moves the operation stick 7 up and down, and the support member 8 when lowering is
It descends further below the upper surface of the hearth roller 4 without interfering with the hearth roller 4, and scoops up the rider 5 sent onto the hearth roller 4 from below.

Reference numeral 9 denotes an iris for temporarily storing the wire rod to be wound down, and this iris is connected to a plurality of elevating mechanisms (for example, hydraulic cylinders) 10 and a guide 11 erected on the heat retention furnace body 1.
An elevating body 12 consisting of an annular hollow body held horizontally by a lift body 12 and an elevating body 12 that is hung at equal intervals from the periphery of an opening 13 formed in the center of this elevating body 12 and penetrated into the heat retention furnace body 1. a plurality of operating shafts 14, a finger 15 that is attached to the lower end of each operating shaft 14 and maintains a horizontal posture on the same plane, and each operating shaft 1
an actuating lever 16, for example keyed at the top end of 4;
and a connecting member 17 that connects the tips of these actuating levers 16, and a cylinder device 18 that provides rotational movement to one of the actuating levers 16. By moving up and down integrally and rotating one actuating lever 16 by operating the cylinder device 18, this movement is simultaneously transmitted to all actuating shafts 14 and the fingers 15 are extended or retracted at the same time.

That is, the iris 9 is initially at the upper limit position and receives the wire being wound down. When the processing of the preceding coil is completed and the rider operation mechanism 6 has risen, the iris 9 starts descending and stops at the lower limit, and the finger rotation mechanism, that is, the cylinder device 18
All the fingers 15 are rotated in the storing (opening) direction in one motion, and the stored wire rod is dropped onto the support member 8.

Note that this embodiment shows the case where the present invention is implemented as a hot reforming equipment, but in the case of cold winding, the operating shaft 14 may be removed from the configuration of the iris 9, and the finger and its rotation may be replaced. A structure in which the mechanism is directly connected to the elevating body may be adopted, and in this case, the operation stick 7 of the rider operation mechanism 6
Coating of thermally insulating castable is omitted.

(Effects of the invention) As explained above, the invention is configured such that the iris for temporarily storing the wire can be raised and lowered,
Therefore, the distance between the wire rod and the rider during delivery can be shortened, and damage to the surface due to falling and impact to the rider can be prevented.
