するものである。Pile drivers or hydraulic presses used in civil engineering or twisting construction work are required to be free of noise and slow movement when the work site is close to human residences. However, there are no existing pile driving machines, punching presses, etc. of this type that have satisfactory functions, and the industry is currently strongly demanding the development of such machines. In view of this, the gist of this invention, which aims to provide a round pressure generating device that generates noise and vibration, is to provide a middle boat on the upper side of the lower end of a cylinder whose upper and lower ends are sealed, and to move the screws in the cylinder to the upper part of the cylinder. The supply of O pressure oil and the O# oil from the middle boat accelerate downward to give kinetic energy to the piston and its integral parts, and the piston descends and the middle part closes the piston, causing the piston to suddenly move. Decelerates and moves the piston downward
11l! The hydraulic pressure suddenly rises to break the hydraulic pressure.
It is something to do.

す。Next, the operation of this embodiment will be explained. When the piston saw is located at the foreshadowing line at the upper end of the cylinder L, the switching valve L is operated and the hydraulic pump J supplies zero pressure forceps from the upper boat to the upper part of the cylinder / via the conduit D, and the piston saw moves to the piston reflex 1 Hehe, the weight is accelerated by the pressure oil and its own weight, and it descends. When the lower end of the piston lλ reaches the upper end of the Chubu Boat 3 and the Chubu Boat 3 starts to close, the piston reaches its maximum descending speed and decelerates to the J Kojikan.
When the lower end of the piston lλ reaches the lower end of the middle boat 4I and the middle boat 4I is closed, the piston lλ stops. In this case, the energy of the motion possessed by the piston L, piston rod J, weight l, etc. is transferred to the cylinder leg via the pressure oil that is densely filled in the cylinder l below the lower end. part/j and the pile WK are transmitted, and the pile W is driven downward. After the pile "W" is driven, switch the switching valve t and connect the conduit 9.
connect the tank//llz and the conduit 1oti to the discharge port of the noodle I pump I, raise the piston/J, and complete the pile driving cycle (111)/recycle ζ from now on.

うに形1成されて−る。A case in which this invention can be applied to a punching press machine is shown in Fig. 2, where the same reference numerals as in Fig. 1 are used to designate the same member shapes as those in Fig. 1. 11, but the legs 71 are installed on the floor. The 17th company building is a hydraulic cylinder, which is located in the t, tVh-frames shown in the figure, and the upper die lde is connected to the lower end of the bisshin-rad it, and the lower die lde is opposite to the upper die lde. is fixed on the shelf rod. At the upper end of the oil cylinder 17, there is a safety check valve, a conduit connected to the lower boat J through the check valve, a check valve, and a switchover valve JJ. It is connected to the pressure pump λ6 and the large conduit 7 through the check valve JJa upper boat side to? The conduit Jt is arranged so that the check function can be released by pressure II. In addition, the lower end of the 111J hydraulic cylinder 17 is connected to the 111J switching valve control via a conduit 19.
Damn it, Monkiri switching valve! The tank JO is also configured to communicate with the tank JO.

It descends steadily and the hydraulic oil is discharged from the central boat stop, but after the piston/J blocks the central boat stop, the hydraulic oil below the piston/JO eats up the piston/J. It is subjected to great auspicious pressure due to the kinetic energy of ζ
First hydraulic cylinder 170 via conduit JJ
Supplied to the upper part, the upper die IT suddenly receives a strong pressing force and punches out the sheet metal P by the cooperation of the lower die JO and O. After that, the switching valve L and the switching valve K are switched, and the piston /J, return to the upper part of the upper die and do the work by yourself.

ン田ツドを省略することがで自る。According to this invention, as described above, both upper and lower ends are sealed and the cylinder is provided with a middle boat in addition to the upper hoard and the lower boat, and the piston is accelerated downward by pressure oil from the upper boat, and the piston and the The structure is such that the lower piston blocks the middle boat, causing the piston, etc. to suddenly decelerate and generate large pressure in the cylinder below the piston. Therefore, when used in a pile driver, vibration and noise are not an issue, making it suitable for construction work in urban areas, and when used in a punching press, it produces less vibration and noise compared to presses that use inertia. Shockingly hitting the same number as the inertial press machine
The durability of the upper die and the lower die is as good as that of china clay because the die is not forced to punch at a low speed as in the case of a normal hydraulic press. In addition, by increasing the weight of this inventor's screw, the weight and piston head can be omitted.
