Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a carrier used when annealing a coiled wire wound by a winding machine.

(Prior art) As a conventionally known carrier of this kind, a cylindrical body for inserting a hollow part of a steel wire coil is fixed upright in the center of a substrate made of a steel plate, and the coils are stacked horizontally on the substrate. However, if the weight of the coil exceeds 2 tons, there is a risk that the bottom layer of wire may be deformed by the weight of the top wire, that is, the coil's own weight, during annealing. Only 2 tons or less of wire can be annealed in a single annealing process, which is extremely inefficient, and since the inner diameter of the coil is rarely affected by direct heating by hot air, the outer diameter of the coil is Compared to conventional methods, it requires a longer heating time, annealing time becomes longer, and the fuel cost for the annealing furnace increases, among other disadvantages.

(Purpose of the invention) The present invention eliminates and solves the drawbacks of the above-mentioned conventional technology,
The object of the present invention is to provide a carrier for annealing wire rods that has good work efficiency and fuel efficiency for an annealing furnace.

(Example) That is, a cylindrical body 3 with a plurality of holes 3 ₁ ... 3 ₁ is fixed upright in the center of a horizontal base frame 2 consisting of a plurality of frame members 2 ₁ ... 2 ₁ , and A lower carrier 1 consists of ^a guard frame 4 made up of a plurality of frame members ^{4 1 .} A cylindrical body ⁷ having a plurality of holes ₇₁ ... ₇₁ is fixed upright in the center of a horizontal base frame 6 consisting of a horizontal base frame 6, and a plurality of frame members surround the cylindrical body 7 at intervals. A guard frame 8 consisting _{of 8 1} . It is characterized by comprising an upper carrier 5 having a diameter that can fit into the upper end portion of the cylindrical body 3 of the lower carrier 1.

In FIGS. 3 and 4, reference numeral 9 denotes a hanging ring for hanging a hook at the tip of a crane wire, which is integrally fixed to the upper end of the cylindrical body 7 of the upper carrier 5 and the guard frame 8 via a frame material.

(Function of the invention) Next, in accordance with the above-described structure of the invention, the specific usage and operation of the carrier of the invention will be explained with respect to the illustrated embodiment.

The base frames 2 and 6 of the upper and lower carriers 5 and 1 shown in Figs. 1, 2, 3 and 4 are respectively made of frame materials 2 ¹ ... 2 ¹ , 6 ¹ ... 6 ¹ such as rods or pipes. Therefore, if wire rods are placed on these base frames 2 and 6, there is a risk that the lowermost wire rods will rub against these frame materials and be scratched, so a guard is placed in the center on the base frames 2 and 6. A steel plate having a hole having a diameter larger than that of the frames 4 and 8 is placed in advance so that the hole is inserted through the guard.
Further, a plurality of holes or notches are previously formed in the steel plate to improve the convection of hot air.

Then, one unit (within a weight of 2 tons) of wire is inserted from above into each of the upper and lower carriers 5, 1 and placed on the base frames 2, 6 so as to pass through the guard frame.

Next, the lower carrier 1 is placed on a roller conveyor (not shown) for transport into the annealing furnace, and the upper carrier 5 is suspended above this by a crane.
When the lower end extension 7 ₂ of the cylindrical body 7 is brought to a point where it coincides with the upper end of the cylindrical body 3 of the lower carrier 1 and lowered, the outer diameter of the extension 7 ₂ becomes smaller than the inner diameter of the cylindrical body 3. Since the extension part 7
₂ fits into the upper end of the cylindrical body 3, and the upper carrier 5
The base frame 6 is placed on the upper end of the guard frame 4 of the lower carrier 1.

In this state, the upper cylindrical body 7 has an extension 7
₂ is fitted into the upper end of the lower cylindrical body 3 so that there is no misalignment in the lateral direction, that is, in the direction of conveyance by the conveyor. Also, the upper carrier 5 will not fall off from the lower carrier 1.

When these carriers are stacked, the load of the wire supported by the upper base frame 6 is transferred to the base frame 2 through the cylindrical body 3 of the lower carrier 1 and the guard frame 4.
There is no burden on the lower wire rod, and the lowermost wire rod only bears a weight of less than 2 tons, which is the allowable amount, so that it will not be deformed during annealing.

In addition, when heated by the burner in the furnace, the hot air that enters the lower end of the cylinder 3 from between the rollers of the conveyor rises through the plurality of holes 3 ₁ ... 3 ₁ and the holes 7 of the cylinder 7 in the upper part. ₁ ...7 The air is blown out from ₁ and heats the inner diameter side of the coil. Furthermore, since the base frames 2, 6 and guard frames 4, 8 are transparent through the frame material, the cylindrical bodies 3, 7 and the guard Hot air rises between the frames 4 and 8 and heats the inner diameter of the coil as well.

(Effects of the invention) As described above, according to the carrier according to the invention, it is possible to stack a plurality of carriers on which wire rods are to be placed, and each carrier has a weight such that the lowermost wire rod does not deform due to the weight of the coil. Since the carrier is designed to hold one unit of wound coil, it is efficient because multiple units of coil can be annealed in one annealing process, and the carrier of the present invention has a transparent frame and Since it is constructed of a perforated cylindrical body, it has good thermal efficiency in the annealing furnace, helps to shorten working time and fuel costs, and has many practical effects such as being lightweight.

In this embodiment, the outer diameter of the cylindrical body extension 7 ₂ of the upper carrier 5 is made smaller than the inner diameter of the lower cylindrical body ₃ to enable fitting. It goes without saying that the outer diameter of the body 3 may be larger than that of the body 3 so that the upper carriers can be fitted together, and that the upper carriers may be stacked in two or three tiers.
