wherein said linking member converts a rotational motion into a linear motion.
4. The molding manufacturing apparatus according to claim 2, wherein said driving source includes a fluid cylinder for actuating said movable punch in the forward and backward directions.
5. The molding manufacturing apparatus according to claim 1, further comprising a control unit that detects a travel distance of said movable plate arid controls said driving mechanism according to the detected travel distance.
6. The molding manufacturing apparatus according to claim 1, wherein said driving mechanism includes a cam mechanism having a cam follower and a cam groove.
7. The molding manufacturing apparatus according to claim 1, wherein said fixed die has a back forming surface for forming a back surface of the end portion and said movable punch has a front forming surface for forming a front surface of the end portion, and
wherein said back forming surface and said front forming surface bend and press the end portion of the molding body to bend at either a substantially right angle, an acute angle or an obtuse angle.
8. The molding manufacturing apparatus according to claim 1, further comprising:
a heating unit which is provided to said fixed table and heats a back surface of the end portion.
9. The molding manufacturing apparatus according to claim 8, wherein said heating unit includes an infrared heating device.
10. The molding manufacturing apparatus according to claim 1, wherein said fixed die includes a positioning groove into which the end portion neighborhood of the molding body is fitted.
11. The molding manufacturing apparatus according to claim 1, wherein said movable plate further comprises a pushing means for pushing a portion of the molding body at a predetermined position excluding the end portion, to prevent displacement in a longitudinal direction.
12. The molding manufacturing apparatus according to claim 1, further comprising a stopper means for stopping said movable plate at a forward end position, said stopper means being provided between said fixed table and said movable plate.
13. The molding manufacturing apparatus according to claim 7, further comprising a second movable punch capable of changing a volume of a cavity formed between said front forming surface and said back forming surface.
14. The molding manufacturing apparatus according to claim 13, further comprising a second driving mechanism including a second driving source and a second linking member which transmits a driving force of said second driving source to said second movable punch to shift said second movable punch.
15. The molding manufacturing apparatus according to claim 13, wherein said movable punch has an internal angle portion being formed continuously with said front forming surface and having a radius of curvature smaller than a radius of curvature of a surface of the end bending portion of the molding body.
16. The molding manufacturing apparatus according to claim 13, wherein said second movable punch is guided by said back forming surface of said fixed die to move forward and backward while being in contact therewith; and
wherein the volume of said cavity is reduced by a forward moving motion of said second movable punch.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A melting apparatus for melt-decontaminating radioactive metal waste so as to allow the metal waste to be recycled, the melting apparatus comprising:
a melting furnace comprising a crucible into which the metal waste is input, and an induction coil wound around the crucible to melt the metal waste using a current induced by electromagnetic induction, the induction coil having a hollow hole in which a cooling fluid flows;
a high frequency generator applying a high-frequency current to the induction coil;
a ladle supplying molten metal, from which slag has been removed in the crucible, into molds;
