Title: Die for cold forging
Inventor: OGAWA MASUJI
IPC: B21J13/02
Filed: 1983-02-14
Abstract: PURPOSE:To obtain a titled die that prevents damage of the first forming member and positions both members easily and surely by dividing the first forming member raidally into plural sections and forming a swelled circular arc face on the side of contact between the end of divided section and the second forming member. CONSTITUTION:When forging a nut, the projected tip of a knock out pin K is placed in the forming hole 14 of the first forming member 13. Roughly forged nut material M is put in the hole 14. Under this condition, the material M is pressed by an extruding pin 22 from above the body in the direction of formed convcavity 18. Consequently, external shape of the nut is formed accroding to internal shape of the concavity 18 and hole 14. The distance between inner bottom faces of the concavity Ma of the material M is narrowed by a pin K and projection of the pin 22. As the member 13 is divded before-hand, even if large pressure is applied to inner face of the hole 14 at the time of forging the nut, damage of the member 13 from the corner part of the hole 14 can be prevented before it occurs. Further, as the circular arc face 15 of each divided section 13a is fitted to the concavity 19 of the second forming member 16, positional deviation between the section 13a and formed concavity 18 can be prevented.

IPC: B65H3/52
Filed: 1979-02-28
Abstract: PURPOSE: To prevent the shrinkage of a copy due to buckling when feeding is stopped and when a friction roller rotates by the friction force against the sheet by making a clutch on the feeding roller side and a one-way clutch intervene.  
     CONSTITUTION: When a copy is put on the copy setting plate 6, the feeding roller 5 rotates and arrives at the contact point of the friction roller 7 and the separation belt 8. As a result, only the lowermost copy is fed. In this case, since the separation belt 8 is a stationary fixed member, twists do not occur. After copies are fed subsequently, the final copy arrives at the fixed location and the feeding roller 5 stops. The friction roller 7 rotates negatively by the friction force against the copy, but since one way clutch is inserted into the pulley 22, the rotation of the firction roller 7 is not transmitted to the feeding roller 5. Even when the next copy is put on the plate, it is not fed, thereby preventing its shrinkage.
