Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an apparatus for generating an impact water pressure used for molding using fluid pressure, in particular, a hammer moves at high speed in a cylinder, and an impact is generated in a water pressure chamber directly connected to the cylinder. This invention relates to an impact water pressure generating device that generates water pressure.

This type of impact water pressure generating device is capable of shockingly generating water pressure of several thousand atmospheres, which cannot be easily generated with ordinary pumps, and is used in industry. Although this is extremely useful, since the configuration is such that high-speed hammers generate water pressure by plunging into the water in the water pressure chamber, the hammers and water pressure chambers, which are subject to friction with each other at high speed and high pressure at the same time, are regularly It is necessary to perform 9 removals and 1 repairs.

As shown in Figure 3, this device generally has a water pressure chamber fitted and fixed on top of the bed, a long cylinder on top of it, and a compressed air supply and interruption system on top of it. A valve device is provided to control the following. This valve device usually has many pneumatic pipes, electrical wiring, etc. fixed to it.

Conventionally, for example, a hammer in a cylinder was removed for repair.
To remove it, first remove the piping and wiring to remove the upper valve device, then lift and remove the valve device that is inserted into the upper end of the cylinder from above, and then insert it into the water pressure chamber from above. Lift the cylinder up sufficiently until it no longer fits into the hammer inside, then slide it to the side and remove it. Since I had to take out the hammer IILe for the first time after that, it took a lot of effort to take out the hammer IILe. Furthermore, reassembly after repair requires a lot of time and effort since all the disassembly and assembly operations must be performed in the reverse order of the above.

The present invention aims to eliminate these conventional drawbacks, and makes it possible to quickly and accurately remove and assemble parts such as hammers that need to be repaired or replaced in a short time and with ease.
The purpose of the present invention is to provide a highly safe device with a simple configuration and an economical form.

Another object of the present invention is that the center shafts of the upper and lower cylinders can be easily reassembled after disassembly. In addition, it is possible to remove the internal valve or remove the water pressure chamber without moving the valve body up or down, which saves a lot of time during conventional repairs. The object is to provide a device that can solve problems that require time and manpower.

The present invention relates to an impact water pressure generating device in which a hammer moves at high speed inside a cylinder and generates an impact water pressure in a water pressure chamber directly connected to the cylinder. V/ Ih no t

An upper 7 flange and a lower flange are provided on the outer periphery of the upper and lower cylinders, respectively, and a mounting plate is removably attached to the iron flange, and a fittable reference ring is fitted to the outer periphery of the 7 flange. This is an impact water pressure generating device which is fixed to the mounting plate and further tightened by a stator between the upper flange and the lower 7 flanges.

In Figures 1 and 2, the upper cylinder 1 and the lower cylinder 2, which are divided by a plane perpendicular to the central axis of the cylinder, have a ring-shaped upper 7 flange 3 and a lower 7 flange 4 on their outer peripheries, respectively. Welded and prepared, both 72-inches 3 and 4 are attached to the cylinder 1,
The joint surface is arranged on the same plane as the dividing surface of No. 2.

Both 7 langes 3.4 are made of a cylindrical body having 2,000 faces perpendicular to its central axis on both end faces, with a hole drilled in its center concentrically with the cylinder and having the same diameter as the outside diameter of the cylinder. Consists of a ring body with the same dimensions except for. Therefore, among the upper 7 lunges 3, I! ! is the outer PI of upper cylinder 1:
Welded, the lower and side planes are on the same plane as the dividing plane of the cylinder, and the upper 7 flange outer surface 5 is cylindrical with the central axis of the cylinder l as the axis, and the upper surface is on the same plane as the dividing surface of the cylinder. The inner circumference of the lower 7 langes 4 is parallel to the lower cylinder 2.
The upper plane is on the same plane as the dividing surface of the cylinder, and the outer surface 6 of the lower 7 flange is cylindrical with the center axis of the cylinder 2 as its axis, and its diameter is that of the upper 7 lange. The diameter of the outer surface 5 is the same as that of the cylinder, and the lower surface is a plane parallel to the upper plane.

The upper 7 flange 3 has a plurality of mounting plate bolts 10 on its upper plane, a disc-shaped mounting plate 8 having a hole in the center concentric with the cylinder and having a diameter sufficiently larger than the outer diameter of the cylinder.
It can be freely removed. In this case, the hole in the center of the mounting plate 8 may be large enough to allow the mounting plate 8 to slide around the outer periphery of the cylinder.

Furthermore, a 7-flange-shaped mounting portion 1 is attached to the above-mentioned mounting [8], which can be adjusted with an extremely small gap over the total length of each cylinder of the upper 7-lange outer surface 5 and the lower 7-lange outer surface 6. The reference ring 7 is firmly fixed to the mounting plate 8 with a reference ring mounting bolt 9 at a position where the reference ring 7 is fitted to the upper 7 flange 3 and the lower 7 flange 4 to align the center axes of the cylinders. However, it goes without saying that the mounting plate 8 and the reference ring 7 may be constructed as one piece from the beginning. In this state, the upper 72 langes 3 and the lower 7 langes 4 are configured to be tightened by a stator, for example, a plurality of tightening poles 11.

In addition, if the degree of centering of the cylinder is not so strictly required, that is, if a relatively large gap is allowed between the cylinder and the hammer, the reference ring 7 and the mounting plate 8 may not all be 360° circular. , 18σ, it is no longer necessary to shift the mounting plate 8 upward and hold it, and it can be pulled out laterally, which further simplifies the work.

Furthermore, by using two semicircular plates instead of one circular plate with a hole, the mounting plate 8 can be easily removed from the cylinder if necessary, and the upper
There is no need to insert the mounting plate 8 into the upper cylinder 1 before welding the flange 3 to the upper cylinder 1, which is convenient.

In addition, if the cylinder can be moved even slightly in the vertical direction, move the upper cylinder 1, lower cylinder 2, /l top, and upper flange 3.
The joint surface of the lower 7 flange 4 is formed with an uneven surface in the circumferential direction or radial direction to improve the sealing condition of the cylinder, which is convenient for relating to the bolt hole. In the case of joints, the joint surfaces of the upper cylinder 1 and lower cylinder 2 and the joint between the upper 72 flange 3 and the lower 7 lange 4 may be arranged on different planes.

As shown in FIG. 3, the dividing surface constructed in this way is formed by a cylinder having a cylinder 712 movable up and down inside thereof, which is formed at two locations separated by a distance L1. This distance L1
If L2 is the full length of the hammer 12, then L2 is also set to be slightly longer, and the lower dividing surface is provided slightly above the top end position when the hammer 12 is at rest. By attaching and detaching or separating a part of the cylinder, it is possible to easily disassemble and assemble the cylinder at a place where it is assembled using a normal spigot without having to disassemble it.

In addition, a valve device is inserted and fixed at the top of the cylinder, which has the role of supplying and shutting off compressed air to move the cylinder at high speed within the device while aligning the center at the in and low points. is inserted into the upper end of the water pressure chamber 13 and centered and fixed with a spigot, and is also centered and fixed with a spigot in the bed surrounding the water pressure chamber 13. A large number of air piping, electrical wiring, their protection tubes, etc. are fixed to the valve device.

Therefore, when removing the hammer 12 and reassembling it after repair, first tighten the tightening bolts at each divided part of the cylinder.
1) Loosen 1G and move the mounting plate 8 slightly above 11 to which the reference ring 7 is fixed, and the outer surface of the lower 7 langes will come out. In this state, the upper and lower cylinders 1.2 are not relatively restrained at each dividing point, so
Of the cylinder divided into three parts, the middle cylinder can be removed by horizontally shifting it.

The upper cylinder of the three parts is fixed to the valve arrangement and remains in place supported by piping or a suitable support structure (not shown). The cylinder directly connected to the water pressure chamber 13 is also held stationary. In this way, a space with an interval of h is created between the cylinders, so a long hammer can be lifted up from inside the lower cylinder and taken out from the space h.

Next, to reassemble the repaired hammer 12, the hammer 12 is suspended in a cylinder directly connected to the hydraulic chamber 13 using the space L1, and then the intermediate cylinder is pushed into the space L1 from the side. At this time, at each split point, the mounting plate 8 can move upwards with the reference ring 7 fixed, so it is moved slightly upwards and the reference ring 7 is slid onto the outer surface 6 of the lower flange from above. Fit them together. That is, the reference ring 7 can be easily fitted by slightly moving the cylinder being assembled back and forth, right and left. After that, the mounting plate bolts 10 are tightened, and the tightening bolts 11 are further tightened firmly, and the center axis of the divided cylinders is completely aligned by fitting the outer surfaces of the upper and lower flanges and the reference ring 7 at each divided point. It can be assembled automatically in a matching state.

That is, by horizontally shifting and removing only the middle part of the cylinder, disassembly and assembly including repair of the hammer 12 can be carried out, and it is possible to easily disassemble and assemble other parts without requiring a great deal of effort and time. □The central axes of the cylinders can be aligned.

The purpose can also be achieved by providing the cylinder with two or more dividing surfaces as described above, and making the intermediate portion removable depending on the length of the hammer, or by providing two or more dividing surfaces so that they can be moved horizontally.

The present invention is an impact water pressure generating device in which a hammer moves at high speed inside a cylinder and generates impact water pressure in a water pressure chamber directly connected to the cylinder. A soil flange and a lower flange are provided on the outer periphery of the upper and lower cylinders, respectively, and a mounting plate is removably provided on the armpit flange. By fitting a fittable reference ring around the outer periphery and fixing it to the mounting plate, and further tightening the upper 7 langes and lower 7 langes with a stator, this can be avoided with conventional structures. It is possible to provide an impact water pressure generating device that can significantly shorten and reduce the enormous amount of effort required for disassembling and assembling work that would otherwise have been required, and that can achieve perfect alignment of the central axes, which has an extremely large practical effect. .
