Title: Punch pressing device
Inventor: UNAI RYUICHI
IPC: B21D45/06
Filed: 1992-11-18
Abstract: PURPOSE:To hold slugs pushed into a die in the die by frictional force, and to enable a continuous punch pressing work without moving upward the slug by forming a tapered part opened upward a little in the upper part of the inside surface of the die. CONSTITUTION:When a metallic plate 3 is punched by a die 1 and a punch 2, on the lower face of the metallic plate 3, the upper end of a tapered part 9 in the die 1 becomes a cutting edge and a cutting face 5 is formed, and also, a rupture surface 6 is formed. Dimensions of the cutting face 5 of slug 4 in this punching process coincide with the inner dimensions of the upper end of the tapered part 9, that is, (a)+2e, and its dimensions become small by contraction caused by the distortion recovery. On the other hand, when punching is finished, the slug 4 is allowed to go into a land part 7 of the die 1 by the punch 2, and since the inner dimensions (a) of the land part 7 are smaller than the inner dimensions (a)+2e of the upper end of the tapered part 9, friction to the inside surface of the die 1 is not lost even by the contraction of the slug 4, and the slug 4 is held in the land part 7.

Filed: 1993-12-27
Abstract: PURPOSE:To change the electron density of a plasma beam, and to control the discharging voltage by giving the bias potential to an electrode, which contacts with the plasma beam closed by the magnetic filed generated by a magnetic field generating means. CONSTITUTION:A permanent magnet 24 is supported on a fitting bracket 25 fixed to the bottom of a chamber 11 so that the plasma beam 18 passes through the its center. Since this magnet 24 forms the magnetic field grade, which is to be quickly changed, along the orbit of the beam 18 to hinder the flow of electron, the beam 18 is left this part under the semi-closed condition. Electron density of the beam 18 under the semi-closed condition is larger than the density of ion due to the thermal diffusion to step up the discharging voltage. A discharging voltage control electrode 26 is arranged at a position, which contacts with the beam 18, and voltage is supplied from a bias power source 27. When the bias voltage is changed, electron density of the beam 18 is changed to change the discharging voltage. Discharging voltage is thereby controlled by changing the bias voltage.
