Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for adjusting the tightening of the plates during pressure closing in an open plate type overpass machine having a large number of plates.

Conventionally, this type of perforation machine used a hydraulic cylinder to close the plate by pushing the pressure plate with a rod, but since it was necessary to maintain a gap that would allow the plate to be opened, the rod had to be made longer. The disadvantages include that the large hydraulic cylinder increases the height of the equipment, and that the retracting rod takes up space.

This drawback could be eliminated by using a bending/extending member operated by a small cylinder as shown in Figure 1 as the pressurizing device, but the rubber gaskets of the plates or the frame interposed between the plates would fatigue and age. The total length of the closed plates may be shortened. However, with a pressurizing device for a bending/stretching member, the bending/stretching member can only extend a certain length, and therefore the plate cannot be sufficiently compressed and closed. This resulted in the problem of the raw solution spewing out from the board and frame.

The present invention solves the above problem by providing an adjusting device that can tighten the plate in addition to the pressurizing device using the bending and stretching member.

Hereinafter, an illustrated embodiment of the present invention will be described. In the embodiment shown in FIGS. 1 to 3, 1 is a plate, and 2 is a pressing plate, each of which is mounted on a rail 3 by a traction device (not shown). move. Reference numeral S denotes a bending/extending member, which is made up of a pair of actuating plates 4a, 4b which are rotatably axially connected at the center thereof. One end of one actuating plate 4b is rotatably connected to the center of the pressing plate 2, and a cylindrical portion 4c provided at the other end of the other actuating plate 4a.
By inserting a shaft 5b supported between brackets 5a of the slide member 5, the operating plate 4a is rotatably connected to the slide member 5. The slide member 5 can be slid by engaging the arms 5c on both sides with the rail 3. Further, the tip of a rod 6a of a hydraulic cylinder 6 which is swingably arranged is connected to the central shaft portion which is the bending and stretching point of the bending and stretching member S, so that the bending and stretching member S can be bent and stretched by moving the rod 6a up and down. It is configured. Furthermore, reinforcing pieces 4d that come into contact with each other when the bending member S is extended are welded to the respective actuating plates 4a and 4b. A characteristic feature of this example is that a wedge member 8 is disposed between the slide member 5 and the end fixing portion 7 side. That is, a guide member 9 having an inclined portion that comes into contact with the inclined surface portion of the wedge member 8 is fixed to the fixed portion 7,
A wedge member 8 is interposed between the guide member 9 and the slide member 5. The wedge member 8 has a handle 10a.
The threaded rod 10 is provided by engaging the lower end protrusion 10b of the threaded rod 10 with the upper end groove 8a,
A portion of the threaded rod 10 is screwed into a female threaded portion of an arm portion 7a provided on the fixing portion 7, thereby stably disposing the wedge member 8 in a suspended state. In addition, by passing the bolt B passed from the fixing part 7 through the respective insertion holes 9a and 5d, and screwing the bolt B with the nut N on the slide member 5 side, it can be used as a locking tool for fixing the position of the interposed wedge member 8. There is. Further, since the wedge member 8 has a frame shape with a hollow portion 8b, it can move up and down regardless of the presence of the bolt B passing through the hollow portion 8b.

Next, the operation of this example will be explained. First, from the closed state shown in FIG. 1, the cylinder 6 is operated to lower the rod 6a. As a result, as in the conventional case, the bending member S extends and presses the plates 1, . . . through the press plate 2 to close the plates (see FIG. 4). In this state, the extended state of the bending member S is locked by the contact of the reinforcing piece 4d. If the closed state of this board is appropriate, you can pour the stock solution in this state and use it for a while, but if you use it for a long time, the rubber gaskets on the board and frame will age and the total length of the board will become shorter. If this happens, there will be insufficient pressure on the plate. In such a case, the wedge member 8 is moved downward by turning the handle 10a before the bending member S presses the plate. As a result, the slide member 5 is pressed by the wide portion of the wedge member 8 and moves toward the plate (see the imaginary line in FIG. 3). In this state, the nut N, which has been loosened in advance, is screwed onto the bolt B to lock the wedge member 8. As the slide member 5 moves, the actuating plates 4a and 4b also move toward the plate side.
From this state, the cylinder 6 is actuated to extend the bending member S and press the plates 1, . . . to close the plates.

According to this example, the bending member S is placed closer to the plate by the distance that the slide member 5 moves toward the plate side in response to the lowering of the wedge member 8, so that the tightening of the plate 1 by the bending member S is reduced. As a result of the strong pressure, insufficient tightening of the plate and frame can be resolved, and it is possible to prevent the undiluted solution from spouting out.

Although this example is configured as described above, the present invention is not limited to this. For example, the arrangement of wedge members,
As shown in FIGS. 5 and 6, a similar configuration may be provided between the pressing plate 2 and one end of the bending member S. Further, the shape of the wedge member is not limited. Further, the means for moving the wedge member in the inserting/removing direction is arbitrary, and in addition to the handle type as in this example, the wedge member may be directly operated by hand. In addition, the location of the bending and stretching member is also appropriate.
Alternatively, the plates may be interposed in a group of plates and separated and opposed to each other, and the plates may be closed by pressing.

In short, this invention is the "scope of claims for utility model registration"
This is a plate tightening adjustment device having the following configuration.

Therefore, according to the present invention, since the wedge member is interposed, the plate can be strongly pressed by the extension of the bending/stretching member, which can eliminate insufficient tightening of the plate and prevent the undiluted solution from spouting out. Since it can be fixed in place, there is no problem with its operation, and there is an advantage that a small and simple bending member can be used as a pressurizing plate closing device.
