An inert gas is supplied into 8 and 9 to make the same pressure. In the present invention, the vacuum means a state where the pressure is reduced to a predetermined pressure or lower.
[0028]
Next, the blocking means 21 is opened, and the basket 22 in the material supply chamber 8 is moved to a predetermined position in the main body chamber 6 by the reciprocating cylinder 23. Then, as shown in FIG. 6, while driving the rotary pump 27 of the metal material transfer means F, the vacuum hand 26 is moved to move a predetermined storage portion of the basket 22 —for example, the first (frontmost) storage portion— The metal material 7 is sucked, and the metal material 7 is discharged and set in the cavity portion 28 of the first lower mold 2a.
[0029]
Thereafter, the lower mold moving means E is driven to move the moving plate 16 and the lower molds 2. Then, as shown in FIG. 7, the first lower mold 2a is disposed at the material melting position below the energy radiating section 5 of the high energy heat source section 4, and the second lower mold 2b is disposed at the material supply position. The
[0030]
Then, the arc power source 4a of the high energy heat source unit 4 is turned on to generate a plasma arc 37 between the tip of the energy radiating unit 5 (arc electrode) and the metal material 7 (set in the lower mold 2a), The metal material 7 is completely dissolved to form a molten metal 38. Meanwhile, at the material supply position, the metal material 7 set in the second storage portion of the basket 22 is transferred to the second lower mold 2b by the vacuum hand 26 (as described above).
[0031]
When the metal material 7 on the first lower mold 2a is completely melted, the arc power source 4a is turned off to turn off the plasma arc 37, and as shown in FIG. The lower molds 2 are moved forward by 1 pitch, the first lower mold 2a is disposed at the press molding position, the second lower mold 2b is disposed at the material melting position, and the third lower mold 2c is disposed at the material supply position.
[0032]
Thereafter, at the press molding position, the upper die 1 is lowered by the lifting mechanism K, and the molten metal 38 having a melting point or higher obtained on the first lower die 2a is pressed by the upper die 1 and the lower die 2a. Then, the molten metal 38 is deformed into a predetermined shape, and simultaneously with or after the deformation, the molten metal 38 is rapidly cooled at the critical cooling rate or higher by the cooled upper mold 1 and lower mold 2a. As a result, a product 39 made of an amorphous alloy (in the shape of an elliptical plate) is formed.
[0033]
At the material melting position, the metal material 7 set on the second lower mold 2b is completely melted by the plasma arc 37 from the energy radiating section 5 (similar to the above), and the molten metal 38 is melted. Form. At the material supply position, the metal material 7 set in the third storage portion of the basket 22 is transferred to the third lower mold 2b by the vacuum hand 26.
[0034]
Next, as shown in FIG. 9, the lower plate moving means E moves the moving plate 16 and the lower dies 2... By 1 pitch, the first lower die 2a at the product pick-up position, and the second lower die 2b. Are placed at the press molding position and the third lower mold 2c is placed at the material melting position.
[0035]
9 and 10, at the product pick-up position, the product 39 on the first lower mold 2a is picked up by the vacuum hand 33 of the product pick-up means G, and the product 39 is picked up. Carry in the cylindrical wall part 30. Then, the suction by the vacuum hand 33 is stopped and the product 39 is dropped into the product take-out chamber 9. At this time, the blocking means 31 is open.
[0036]
At the press molding position, the molten metal 38 on the second lower mold 2b is press molded to form a product 39 made of an amorphous alloy. At the material melting position, the third lower mold 2b is formed. The molten metal 38 is formed by completely melting the metal material 7 set on the mold 2c.
[0037]
Thereafter, the lower plate moving means E moves the moving plate 16 and each lower die 2... By 1 pitch, and places the second lower die 2b at the product pick-up position to bring the product 39 into the vacuum hand 33 (similar to the above). And is carried to the product take-out chamber 9 side, and press molding is performed by placing the third lower mold 2c at the press molding position.
[0038]
Then, the lower plate moving means E moves the moving plate 16 and the lower dies 2... By 1 pitch, places the third lower die 2c at the product pick-up position, picks up the product 39 with the vacuum hand 33, and takes out the product. Carry to the chamber 9 side. Then, as shown in FIGS. 1 and 2, the motor M of the lower mold moving means E rotates reversely, the moving plate 16 moves backward, and the first lower mold 2a is returned to the material supply position. This is one cycle from the material supply process to the product picking process.
[0039]
When the metal material 7 in the basket 22 is emptied during the one cycle, the reciprocating cylinder 23 is shortened and the basket 22 is returned into the material supply chamber 8, and the blocking means 21 is closed to close the main body chamber 6. , The basket 22 is taken out, a newly weighed metal material 7 is set, and it is returned to the material supply chamber 8 again. Then, the inside of the material supply chamber 8 is evacuated again and replaced with an inert gas at the same pressure as in the main body chamber 6.
[0040]
Thus, after completion of one cycle from the material supply process to the product pick-up process, the products 39 are repeatedly manufactured in two cycles, three cycles, and when the predetermined cycle is completed, the blocking means 31 is closed and the product take-out chamber 9 is closed. Is shut off from the main body chamber 6 and the product take-off means 32 is opened to take out the products 39 in the product take-out chamber 9 from the outside. When manufacturing again after taking out the product, the inside of the product take-out chamber 9 is evacuated and replaced with an inert gas at the same pressure as in the main body chamber 6.
[0041]
As described above, the apparatus for producing an amorphous alloy according to the present invention replaces the inside of the main body chamber 6 with a predetermined pressure with the inert gas when supplying the metal material 7 from the outside and taking out the product to the outside. Therefore, it is not necessary to evacuate the main chamber 6 having a large space volume again and replace it with an inert gas. Further, the press molding process, the material melting process, and the material setting process are performed. Since a plurality of products can be produced in one cycle by proceeding at the same time, the workability is excellent.
