IPC: B21D28/00
Filed: 1981-03-06
Abstract: PURPOSE:To make piercing without forming burrs by forming an annular groove on a plate by a die having an annular projection and piercing inside of the annular groove to forming side of the annular groove. CONSTITUTION:An annular projection having nearly the same diameter as the hole to be pierced on a plate B is formed on the upper face of a lower die member 1. The plate (b) is placed on the lower die member 1 and an upper die member 3 is pressed from above to plastic work an annular groove C on the plate B. Next, the plate is placed on a cylindrical die 4 which is nearly the same in inner diameter as the groove C of the plate B, and blanking is made from above by a punch 5. A step 6 is formed on the punch 5 and a face D is generated by pressing upper periphery of the hole E of the plate B. By this way, the generation of burrs on the periphery of the hole E can be prevented.

Filed: 1984-02-23
Abstract: PURPOSE:To reduce the variation in the cutting degree due to the variation in the voltage of a battery by varying a voltage applied to a motor from the battery in response to terminal voltage of the battery or the load current of the motor. CONSTITUTION:When an operation is started by a new battery B, a voltage VR is higher than a reference voltage Vm.

At this time, a control voltage of B.R2/(R1+R2) is applied to the gate of a field effect transistor FET, and the applied voltage of a motor is slightly reduced. When the voltage of the battery drops by the used of a battery B so that a voltage VR becomes equivalent to the reference voltage Vm, the output of the amplifier A becomes high level, and the transistor Q1 is turned OFF. At this time, the voltage B of the battery is applied directly to the gate of a field effect transistor FET. Thus, the motor M is fully rotated.
