Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general-purpose straightening machine.

[0002]

2. Description of the Related Art Conventionally, there has been a strain removing machine which presses the strain of a sheet-like metal workpiece to form and deform the workpiece, and removes the strain. A configuration in which a hydraulic cylinder was provided was common.

[0003] However, in such a straightening machine, the work position is limited because the mounting position of the hydraulic cylinder is fixed, and the work must be moved to change the press position. It was inefficient.

Therefore, the present applicant has filed Japanese Patent Application No. 7-2357.
At 39, a lower bed on which the workpiece is placed, a cylinder supporter that straddles the lower bed in the left-right width direction and is movably mounted in the front-rear direction, and the cylinder support for pressurizing the workpiece. A hydraulic press equipped with a hydraulic cylinder movably attached to the upper beam of the section in the left-right width direction has been disclosed as a general-purpose straightening machine.

With this configuration, it is possible to increase the degree of freedom of the mounting position of the workpiece irrespective of the shape and size of the workpiece, thereby greatly improving work efficiency.

[0006]

However, the above-mentioned general-purpose straightening machine still has the following problems.

That is, in such a general-purpose straightening machine, a relatively large lower bed or the like needs to be used in order to widen an object to be processed, so that the installation space naturally becomes large.

When such a general-purpose straightening machine is installed in a factory building, the space becomes a dead space when not used, and the effective use of the entire building is impaired.

When the workpiece is extremely large, it may be necessary to protrude a portion other than the press portion from the lower bed to one side in a large direction. It was very difficult.

An object of the present invention is to provide a general-purpose straightening machine capable of solving the above-mentioned problems.

[0011]

Therefore, according to the present invention, a lower bed on which a workpiece is placed, and the lower bed straddle the left and right width directions and are movably mounted in the front-rear direction. Cylinder support portion, for pressurizing the workpiece, comprises a hydraulic cylinder movably attached to the upper beam of the cylinder support portion in the left and right width direction, further,
The lower bed was a general-purpose straightening machine that was movable with respect to the mounting floor. So if you don't use it,
For example, move to the inner part of the building where it is installed to make effective use of the building, and when using it, move the lower bed to a predetermined location according to the size of the workpiece, etc. for efficient work I can do it.

According to the present invention, the lower bed moves on a rail laid on a mounting floor. Therefore, the heavy-weight general-purpose straightening machine can be smoothly moved to the destination.

Further, according to the present invention, a crane device is mounted on the upper beam. Therefore,
Even if the workpiece is a large heavy object, it can be easily placed on the lower bed or changed in position on the same bed.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a lower bed on which a workpiece is placed, a cylinder supporter which straddles the lower bed in the left-right width direction and is movably mounted in the front-rear direction.
A hydraulic cylinder mounted on the upper beam of the cylinder support so as to be movable in the left-right width direction in order to pressurize the workpiece; and further, the lower bed is movable with respect to its mounting floor surface. The present invention relates to a general-purpose straightening machine.

The lower bed can also be used as a surface plate and is a heavy object having a hydraulic cylinder and a cylinder support. Therefore, in order to move the lower bed, wheels connected to an electric motor or the like are connected to the lower bed. And a rail can be laid on the mounting floor surface so as to be movable on the rail.

With this configuration, it is possible to smoothly move on the rail to a desired location.

The cylinder support portion is formed in a front view portal type by right and left vertical frames erected so as to straddle the lower bed and an upper beam integrally connected between upper ends of both vertical frames. Two are arranged side by side at a certain interval in the front and rear direction,
The lower ends of the front and rear vertical frames on the left and right sides are connected by the lower frame, and lower rollers are attached to the front and rear ends of the lower frame, respectively, and the rails provided on both sides of the lower bed are moved in the front and rear directions. It can be configured freely. As a drive source for moving the cylinder supporting portion, an electric motor disposed on the lower frame, an output shaft of the electric motor and one of the lower rollers are interlocked and connected.

Further, a press device for pressing a workpiece to the upper beam to remove distortion is provided.

The press device comprises a hydraulic cylinder having a bending die detachably mounted at the tip thereof, a hydraulic unit including a hydraulic pump for generating hydraulic pressure in the cylinder, and an inner upper surface of a lower flange formed on an upper beam. And an upper roller that rolls, so that the upper beam can be moved in the left-right width direction.

As described above, according to the present invention, when the general-purpose straightening machine is not used, it is positioned at a predetermined storage location, and if necessary, the lower bed is moved to the predetermined location according to the size of the workpiece. Because it can be moved, space can be used effectively. Moreover, the movement can be performed smoothly along the rail. The rail may be laid on the floor or buried.

Further, a crane device can be attached to the upper beam. It is preferable that the crane device is attached to the front and rear sides of the upper beam so as to swing freely.

That is, some types of workpieces are large and heavy to be moved manually, but the provision of a crane device makes it easy to move or change the position, thereby improving work efficiency. It can be significantly improved.
