An overlapping and progressive forming method for a high-performance multi-element NiAl-based alloy tubular part, including: winding continuously flexible substrates of Ni and Al, and alloying coating continuously or selectively along a width direction or a rolling direction to obtain coated flexible substrates; winding continuously the coated flexible substrates on an outer surface of a core roller according to a sequence of Ni above and Al below to form a Ni/Al laminated structure having a plurality of layers with an outermost layer being a Ni layer, and consolidating with ultrasonic with assistance of a pulse current to combine the continuously wound flexible substrates into a laminated tube blank; and placing the laminated tube blank into a mold, applying a pulse current to both ends of the laminated tube blank for hot fluid high-pressure forming, and synthesizing in-situ to prepare the tubular part with assistance of the pulse current.

A method of progressive processing includes feeding a strip-shaped sheet to a press machine; pressing the strip-shaped sheet with the press machine; and joining the strip-shaped sheet with a new strip-shaped sheet by applying a tape over an end of the strip-shaped sheet located in a direction opposite a direction in which the strip-shaped sheet is fed and an end of the new strip-shaped sheet located in a direction in which the new strip-shaped sheet is fed.

A wire winding device includes a lock jig including a pair of tip end portions configured to approach each other or separate from each other. A control portion of the wire winding device is configured to execute: a step of winding a wire onto a winding drum; and a step of making the lock jig sandwich a pulled-out part of the wire, inserting the lock jig into a clip, and opening the tip end portions of the lock jig against biasing force of the clip to open the clip.

The invention relates to a method for preventing shape changes in metal coils, in particular for preventing a collapsing of newly wound hot coils. In the method, a metal coil, in particular a newly wound hot coil, is rotated about its longitudinal axis intermittently in a first rotational direction and then rotated back in a second opposing rotational direction, or further rotated in the first rotational direction.

A method of producing an amorphous alloy ribbon. The method includes radiating a laser to an amorphous alloy ribbon, while the amorphous alloy ribbon travels or is travelling, to thereby form laser irradiation marks on the amorphous alloy ribbon. Further, when the amorphous alloy ribbon has a traveling speed of S1 m/sec and the laser has a scanning speed of S2 m/sec, the S1 is 0.1 m/sec or more and 30 m/sec or less, the S2 is 1 m/sec or more and 800 m/sec or less, and S2/S1 is 3.0 or more.

A method for cutting a metallic film is disclosed. The method includes: feeding the metallic film between a scoring blade and an anvil at a first speed; feeding a first protective film between the metallic film and the scoring blade; feeding a second protective film between the metallic film and the anvil; moving the scoring blade toward the anvil for applying a pressure onto the first protective film, the metallic film, and the second protective film disposed between the scoring blade and the anvil for making a score along a width of the protective film; and pulling the metallic film having passed between the scoring blade and the anvil at a second speed. The second speed being greater than the first speed. A difference between the first and second speeds causes the metallic film to cut at the score. A system for cutting a metallic film is also disclosed.

Disclosed within are various embodiments that provide for an automated rod coil cutting station for both ferrous and non-ferrous wire rod mills.
