Title: Hydraulically driven closed forging machine
Inventor: OKUMOTO MASANORI
IPC: B21J9/06
Filed: 1983-01-14
Abstract: PURPOSE:To drive thoroughly synchronously top and bottom punches by controlling a solenoid valve for controlling flow rate provided to a circuit for a driving hydraulic cylinder to change a cylinder speed when the difference in the displacement between the top and bottom punches exceeds a set value. CONSTITUTION:A die mounting base 8 is fixed in a prescribed position by a hydraulic cylinder 6 and thereafter the synchronous driving of top and bottom punches 12, 13 is started by cylinders 5, 7 and differential transformers 14, 15 start measuring the displacing rate of the punches 12, 13. When the difference in the displacement between the respective punches exceeds a set value, a selector valve of a solenoid valve for controlling the flow rate of a cylinder on the side where the displacing rate is larger is energized to change over oil paths so that the flow rate is limited by a flow rate control valve, thus decreasing the displacing speed of the punch 12 or 13. When the top and bottom punches are synchronized, the selector valve is reset to the home position and the punches are thoroughly synchronously driven by the repetition of the above-mentioned operation. The difference in the displacement between the top and bottom punches is thus exactly and accurately corrected and the synchronized driving is made possible.

Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the danger of malfunction even without stopping the operation of a radar system at the time of passing through a gate by arranging left and right partition walls for determining a passage so as to make the positions of front ends longitudinally different. SOLUTION: The gate is composed of partition walls P, Q and R partitioning plural passages and the ceiling supported by these partition walls (A).
