Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an integrated manufacturing apparatus for manufacturing products of various cross-sectional shapes, such as wire ronds, rectangular wires, thin wires, and shaped sedge hats, from casting to commercialization.

Conventionally, as shown in Fig. 1, there is a continuous cotton casting apparatus that combines a wheel belt type continuous casting machine and a rolling mill to manufacture aluminum rough drawn wire and copper rough drawn wire. Since a rolling mill with a rolling process of 17 stages is required, the equipment occupies a large area, and maintenance of the equipment is difficult, making it uneconomical.Moreover, the shape of the manufactured product is The facility was limited and could not manufacture shaped materials, square tubes, circular tubes, etc., and was designed exclusively for cotton materials.

A rotary metal extruder is also being considered that consists of a rotating wheel with a circumferential groove and a shoe that makes a part of the circumferential groove wave. Moreover, in the case of a large-diameter feed nut, a considerable amount of heating time is required, which has the disadvantage that efficient extrusion processing cannot be performed.

The present invention was made in order to eliminate the above-mentioned conventional drawbacks, and it simplifies the equipment and greatly reduces the area required by receiving the cast material formed by a continuous casting machine and extruding it directly by a rotary extruder. The object of the present invention is to provide an integrated product manufacturing apparatus that can be reduced in size and that can manufacture products with various cross-sectional shapes with high efficiency.

Below, the embodiment will be explained with reference to the drawings. In the drawing, 1 is a wheel belt type continuous casting machine, which includes a large diameter drum 2 that is horizontally supported on the machine base and can rotate, and a constant interval is maintained at the lower part of the outer periphery of the drum 2. The drum 2 and the steel belt 3 are both synchronously driven.

Reference numeral 5 denotes a spout, and the spout 5 allows the molten metal from the melting furnace 6 to pass through the heat-retaining furnace 1 and pour into the spout of the casting machine 1.

8 is a cast material cast by the casting machine 1, 9 is a pinch roller for pulling out the cast material 8, 9' is a shear for cutting off the tip of the cast material 8, and 10 is a roller for conveying the cast material 8. be.

Reference numeral 11 denotes a metal extruder, and the extruder 11 has a wheel 13 having a continuous U-shaped groove 12 on its outer periphery, and is horizontally supported by a frame 13' so as to be rotatable by a drive device (not shown). The concave groove 12 of the wheel 13 is inserted into the wheel 13.
The shoe 14 covers about 1/4 of the outer circumference in the rotational direction and radial direction.

The front end of the shoe 14 in the wheel rotation direction is provided with a die 15 and a product ejection hole 16 in series.
The structure is such that the material drawn and crushed by the rotation is extruded as a product downward in the figure or to the rear of the extruder 11.

The continuous casting machine 1, rollers 10, and metal extruder 11 described above are arranged in series to form a line.

In the case of a product extruded by the extruder 11, such as a wire rod, a cooler 18 and a winder 19 for cooling the wire rod 11 are disposed downstream of the metal extruder 11.

In the case of manufacturing a thin wire, a small metal extruder 20 is installed to receive and reprocess the wire rod 1γ extruded by the extruder 11, and a cooler 21 and a winding are installed downstream of this extruder 20 to cool the thin wire. The takers 22 are arranged in series.

Further, when manufacturing a shape, a square, or a round tube, a shear 23, a conveyance table 24, and a pallet 25 are arranged in series after the extruder 11.

The material of the above casting material is non-ferrous metal (aluminum,
(steel, lead, various alloys, etc.), but ordinary metals may also be used.

Also, corresponding parts in the conventional example shown in FIG. 1 are given the same reference numerals.

Since the present invention is configured as described above, the wheel belt type continuous casting machine 1 is operated to form a continuous casting material 8 having a substantially rectangular cross section from molten metal, and this casting material 8 is pulled out by pinch rollers 9. , metal extruder 1 via conveyor rollers 10
1.

In the metal extruder 11, as shown in FIGS. 3 and 4, a U-shaped groove 12 formed on the outer periphery of the wheel 13, and
At the entrance of the cavity formed by the shoe 14 that serves as a lid plate,
When a feed stock, that is, a cast material 8 that is slightly larger than the groove 12 is introduced (the first part is indented), the cast material 8 is pulled into this cavity by the frictional force of the three sides of the groove and the rotation of the wheel 13. After the tip reaches the die 15, the tip is crushed and pressurized by the pressing action of the feedstock that is subsequently pushed in, and is put into a hydrostatic pressure state and extruded as a product from the die 15, Thereafter, the product is continuously extruded.

Therefore, by attaching dies of various shapes, we can manufacture not only wire rods and shapes, but also square tubes, circular tubes, etc. using bridge dies or boat hole dies that utilize the welding phenomenon caused by processing heat that occurs when materials are crushed. It is possible to consistently manufacture products with various cross-sectional shapes.

As described above, according to the apparatus of the present invention, it is possible to perform the entire process from casting molten metal to manufacturing products with various cross-sectional shapes. - It is extremely economical as there is no need for cutting, and since the cast material in a high temperature state from the continuous casting machine is directly introduced into the metal extruder to process the product, it is heated compared to the processing of feedstock at room temperature. This method eliminates the need for a machine, eliminates the inconvenience of slowing down processing speed due to a heating machine, and has the advantageous industrial advantage of being able to manufacture products with various cross-sectional shapes with high efficiency, in addition to the above-mentioned integrated manufacturing.
