Title: Die of sheet material
Inventor: ISOWA YASUYUKI
IPC: B26F1/44
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To lengthen the service life of a horizontal punching edge and a vertical punching edge and perform sure punching by both of the punching edges by inclining the horizontal punching edge at a required angle and further setting the horizontal punching edge and the vertical punching edge at locations which do not interfere with a mounting hole of a die cylinder. SOLUTION: A horizontal punching edge 16a is inclined by substantially the same angle so that an end part A located at the side of an end part inclined to the side of upstream of a sheet feeding direction of a die cylinder 19 may be the preceding side of the revolving direction of the die cylinder 19. As a result, large stress is not applied to the die cylinder 19, an anvil cylinder and the horizontal punching edge 16a themselves because the horizontal punching edge 16a is gradually abutted on a sheet material 11. Because the horizontal punching edge 16a and a vertical punching edge 16b in a die 18 are faced at locations where the edges 16a and 16b do not interfere with a mounting hole of the die cylinder 19, each of the punching edge 16a, 16b is surely supported on the outer peripheral surface of the die cylinder 19 over the entire length.  Therefore, sure punching by each punching edge 16a, 16b is made possible.

Filed: 1990-11-30
Abstract: PURPOSE:To reduce a self-discharge and improve the recovery property of the capacity by using a grid made of the alloy composition containing no antimony, and using a positive electrode plate dipped in the salt of an alkali metal or an alkaline earth metal after formation then dried. CONSTITUTION:A grid made of the alloy composition containing no antimony is used, and a positive electrode plate dipped in the salt of an alkali metal or an alkaline earth metal after formation then dried is used. When the grid made of the alloy formation containing no antimony is used, a nonconducting layer is generated on the boundary face between the grid and an active material in the drying process after formation, and this is considered to cause a large self-discharge and the bad recovery property of the capacity. When the alloy containing no antimony is used, the charge and discharge are required several times for charging recovery, however if the grid is dipped in the salt of an alkali metal or an alkaline earth metal after formation, the generation of the nonconducting layer is suppressed. The self-discharge is reduced, and the recovery property of the capacity is improved.
