Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for converging and heat-treating a wire rod that has been hot rolled and formed into a continuous ring shape through a laying cone.

(Prior art) The most commonly used technology for heat-treating hot-rolled wire rods formed into a continuous ring shape is as follows:
There are methods such as a method in which the convergent wire is conveyed while being expanded on a Stelmore conveyor and heat treated by air cooling, or a method in which a heat treatment tank is arranged linearly on the conveyance path and heat treatment is carried out.

However, this method requires a long conveyor equipment and a wide installation floor, and therefore, as seen in the technology disclosed in Japanese Patent Publication No. 58-3019, heat treatment conveyance equipment consisting of a long conveyor and heat treatment It has been proposed to arrange conhairs in parallel with a tank and a cleaning device, but even this method cannot overcome all the drawbacks of conventional equipment, and the heat treatment method is limited.

Another known method is to cool the wire once after winding it, and then perform reheating heat treatment in a batch furnace or continuous furnace, but this method wastes the heat held by the wire, and in addition, the wire must be reheated from the cooled state. Another problem is that heat treatment takes a long time.

As a means to solve the problems of these conventional methods, the applicant sealed a laying cone to the ceiling wall of a furnace placed immediately after the finishing rolling mill, and temporarily held the ring-shaped wire rod drawn from the cone with a temporary holding mechanism. The preheated rider is brought close to the temporary holding mechanism by the rider holding mechanism and its elevating mechanism, transferred to the converging wire temporarily held by this, and lowered onto the conveyor roller at the bottom of the furnace. Patent application 1986-65848 for a winding device for hot-rolled wire rods, which is then transported to a heat retention furnace.
I proposed it in the issue.

(Problems to be Solved by the Invention) The above-mentioned hot-rolled wire winding device exhibits an excellent effect of solving the drawbacks of the conventional device described above, but it A further problem that needed to be solved was that it had to be transported out for proper heat treatment.

The present invention aims to provide a wire winding heat treatment apparatus that can solve these problems.

(Means for Solving the Problems) The present invention temporarily supports and converges the wire led out from the laying cone and is transported by a temporary holding mechanism, and then ascends to a position below the temporary holding mechanism and receives it by a waiting rider. A hot winding device that is lowered and immersed into the heat treatment tank, a heat treatment tank that is directly connected below the hot winding device, has a fixed beam on the inner bottom surface, and has openings with lids on both sides of the top, and this heat treatment tank. The gist is a structure that combines a lidar transfer mechanism that performs up and down movement and back and forth movement in the upper space of the body, and transmits this movement to the rider via an arm rod inserted into the processing tank and a moving beam installed at the tip of the arm rod. It is something to do.

(Function) In the present invention, a heat treatment tank is directly connected to the lower part of the hot winding device, and the convergent wire is processed while being moved along with the lidar in the heat treatment tank, so that the desired heat treatment is performed immediately after winding the wire. can be administered.

It is composed of a long rider elevating mechanism 7. Although the temporary holding mechanism 6 is not shown,
A large number of rotary claws are arranged around the circumference at equal intervals, and the base ends of the claws are operated simultaneously to open and close the entire claw in one motion.The rider elevating mechanism 7 also has a hook portion 8 at the lower end. It is constituted by a plurality of shaft rods 9 provided with a shaft and a shaft lifting means 10 mounted on the heat insulation cover 4.

Reference numeral 17 denotes a rider transfer mechanism, which includes a horizontal frame 18 supported horizontally in the upper space of the processing tank 11, a forward and backward movement means 19 provided on both sides of one end of the frame, and a rider transfer mechanism 18. A plurality of opposing arm rods 20 are deeply inserted into the tank through the long holes 15 formed in the upper part of the processing tank 11, and a plurality of opposing arm rods 20 are fixed to the lower ends of these arm rods 20 and close to the outside of the fixed beam 12. Two parallel moving beams 21
It is composed of. As shown in FIG. 5, the connecting portion between the horizontal frame 18 and the forward/backward movement means 19 does not provide support for the forward/backward movement even if the rider transition mechanism 17 is moved up and down by the vertical movement mechanism described later. Furthermore, as shown in FIG. Consideration has been taken to avoid interference with the hook portion 8. Reference numeral 24 denotes a vertical movement mechanism of the rider transfer mechanism 17, which includes a lever with a roller 26 that is rotatably supported by a bearing 25 at a plurality of front and rear locations outside the heat treatment tank, and a lower end of the lever with a roller 26, respectively. The roller 28 at the end of the roller-equipped lever 26 is always in contact with and supports the lower surface of the horizontal frame 18.

The present invention has a structure as described in the above embodiments, and the empty lidar 16 inserted through the opening 13 of the heat treatment tank 11 is first placed on the end of the fixed beam 12, where it can be moved up and down. By operating the mechanism 24, the rider transition mechanism 1
7 is raised, the rider 16 is lifted up by the moving beam 21, and then the forward and backward movement means 19 is operated to sequentially move the transfer mechanism 17 from a-xb to C shown in Fig. 2. Then, the empty rider 16 moved to position C is raised to a predetermined height by the rider lifting mechanism 7, and the wire rod already converged and supported on the temporary holding mechanism 6 is dropped and transferred onto the rider 16. Next, the rider lifting mechanism 7 is operated in the descending direction, and the wire is further converged by the rider 16a and descends, eventually reaching the fixed beam 12.
The wire is now completely immersed into the tank together with the rider 16a. Next, the lidar transfer mechanism 17 described above is moved upwardly and forwardly to move to the lower part of the opening 14 while performing necessary submerged processing, and when the processing is completed, the lidar is lifted out from the opening 14. In addition,
In the present invention, such winding operations are performed successively at predetermined timings, and during this period, the rider transfer mechanism 17 repeats the operations of raising, moving forward, lowering, and retreating.

(Effects of the Invention) As explained above, the present invention involves immediately immersing the wire that has been wound up by the hot winding device and converged on the rider into a heat treatment tank, and then heating the inside of the tank while performing the required heat treatment. Therefore, the entire device can be made compact and the installation space can be saved, and a device that is easy to maintain and inspect can be provided at a low cost. In addition, according to the present invention, direct patenting in a salt bath (approximately 500 to 600°C) eliminates lead patenting due to transition to secondary processing, which was conventionally required, or direct spheroidization in a salt bath (approximately 700°C). Further, when the salt bath is replaced with boiling water (approximately 95° C.), lead patenting can be simplified by direct patenting.
