[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for press-molding an object to be pressed, particularly a long and heavy object, in two directions, longitudinal and lateral.

[0002]

2. Description of the Related Art FIG. 5 is a sectional view showing the structure of a conventional two-way pressing device. The frame body 40 is composed of a horizontal upper frame 40A and a lower frame 40B and a vertical horizontal frame 4
OC and the hook-shaped frame 40D form a C shape. Two hydraulic jacks are attached to the frame body 40 with their directions changed. The first jack 1 has its cylinder block 1A fixed to the upper frame 40A with the piston 1B facing downward. The second jack 2 has its cylinder block 2A fixed to the horizontal frame 40C with the piston 2B facing the horizontal direction. A horizontal pressing plate 6 and a vertical pressing plate 70 are fixed to the distal ends of the pistons 1B and 2B, respectively. . The pressed body 9 is placed on the lower frame 40B, and a lateral load receiving plate 80 is interposed between the pressed body 9 and the hook-shaped frame 40D. Each of the jacks 1 and 2 is provided with a hydraulic control device for increasing the pressure of the oil 5 in the cylinder block, but is not shown.

FIG. 5 shows a state where the pressed body 9 is pressed in the lateral direction. The hook-shaped frame 40D receives the rightward load of the second jack 2 via the lateral load receiving plate 80. On the other hand, FIG. 6 is a cross-sectional view showing a state where the pressed body 9 is pressed in the vertical direction by the device of FIG. After the piston 2B of the second jack 2 is slightly retracted to the left, the piston 1B of the first jack 1 is driven downward, and the lower frame 4B receives the vertical load.

In FIGS. 5 and 6, pressure is alternately applied to the pressed body 9 from two directions, that is, a horizontal direction and a vertical direction, to press-mold the pressed body 9 into a predetermined shape. However, in this apparatus, if the horizontal pressing plate 6 and the vertical pressing plate 70 are appropriately shaped, the pressed body 9 can be pressed simultaneously from two directions.

[0005]

However, the conventional apparatus as described above has a problem in that the protrusion of the hook-shaped frame is an obstacle, and it is difficult to put the pressed body into and out of the frame body. there were. That is, it is necessary to lift the pressed body once and operate it with the hook-shaped frame in between. When the pressed body is long and heavy, it is operated by a crane. However, a pair of hanging jigs formed so as to grasp both ends of the pressed body and protrude to both sides of the frame body are manufactured in advance. The object to be pressed was suspended by the crane via the tool. In this case, since the pressed body is long, the central portion is necessarily largely bent. In some cases, the pressed body receives abnormal stress only by the lifting operation, and the pressed body becomes defective. In addition, since the central portion of the pressed body vibrates greatly, there is a possibility that the pressed body may hit the nearby object and be damaged if the crane lifting operation is not performed carefully.

SUMMARY OF THE INVENTION It is an object of the present invention to enable a pressed body to be moved into and out of a frame of a frame without being lifted by a crane.

[0007]

According to the present invention, there is provided an apparatus for press-molding an object to be pressed from two directions, that is, a horizontal upper and lower frame and a vertical horizontal frame. A frame body formed into a C shape with the frame,
A first jack attached to the upper frame and having a piston driven vertically in the frame of the frame, a second jack attached to the horizontal frame and provided with a piston driven horizontally in the frame of the frame, and a first jack. A horizontal pressure plate fixed to the piston tip, a vertical pressure plate fixed to the piston tip of the second jack, and a horizontal load receiving plate disposed on the upper surface of the lower frame on the side opposite to the horizontal frame. The lower frame is protruded longer than the upper frame to the side opposite to the horizontal frame, and a vertical pressing plate is formed in an L shape integrally with a vertical load receiving plate horizontally arranged on the lower frame upper surface, and the horizontal load receiving plate is A third pivotally and slidably connected to a side edge of the receiving plate opposite to the vertical pressing plate, the piston including a piston that vertically penetrates the lower frame and moves in and out of the upper portion of the lower frame.
Assume that the jack is fixed to the lower frame on the side opposite to the horizontal frame.

[0008] In this configuration, the piston of the third jack has an oblique notch formed on the side of the horizontal frame at the end thereof, and further has a long connecting portion between the horizontal load receiving plate and the vertical load receiving plate. It is assumed that the hole and the guide pin are fitted to each other.

[0009]

According to the structure of the present invention, the lower frame projects longer than the upper frame toward the side opposite to the horizontal frame, and a vertical load receiving plate on which a pressed body is placed is provided at one end of the vertical pressing plate. The lateral load receiving plate was pivotally and slidably connected to the receiving plate. Further, a third frame which receives a lateral load on the lower frame is provided.
Jack was provided.

When setting a pressed body in such a device, first, the piston of the third jack is retracted downward from the lower frame, and the lateral load receiving plate is lowered horizontally.
The piston of the second jack is driven to the side opposite to the horizontal frame, and the vertical load receiving plate is pushed out of the frame of the frame body. After placing the pressed body on the vertical load receiving plate at this position, the piston of the second jack is driven to the horizontal frame side, and the pressed body is placed in the frame of the frame body. Next, the piston of the third jack is driven above the lower frame to raise the lateral load receiving plate to make it vertical. When the piston of the second jack is driven again in the anti-lateral frame direction in this state, the piston of the third jack receives the load via the lateral load receiving plate, and the pressed body is pressed in the horizontal direction. When the piston of the second jack is returned to the horizontal frame side and the piston of the first jack is driven downward, the lower frame receives the load via the vertical load receiving plate, so that the pressed body is pressed in the vertical direction.

When taking out the pressed body from such an apparatus, the piston of the first jack is driven upward and the piston of the second jack is driven in the horizontal frame direction to release the pressing force on the pressed body. Next, the piston of the third jack is retracted below the lower frame. The piston of the second jack is driven in the direction opposite to the horizontal frame while the horizontal load receiving plate is tilted horizontally on the lower frame, and the vertical load receiving plate is pushed out of the frame of the frame body.

In such a configuration, an oblique notch is formed at the tip of the piston of the third jack. This notch is in contact with the lateral load receiving plate when the lateral load receiving plate is raised or laid down, and the lateral load receiving plate can be automatically rotated in conjunction with the vertical movement of the piston of the third jack. it can.
Further, since the connecting portion between the horizontal load receiving plate and the vertical load receiving plate has a configuration in which the elongated hole and the guide pin are fitted to each other, it is possible to reliably secure the pressing allowance of the pressed body in the lateral direction. .
