Description

[Detailed Description of the Invention] The present invention relates to a straightening device for metal sections, such as steel sheet piles and sections.

Metal shapes can be deformed in a wide variety of ways, including bending, twisting, and bending.

The object of the present invention is to provide an apparatus for simply correcting the distortion of a rising portion of a cross section of a steel sheet pile, etc., as shown in FIG. 5, among such distortions of metal sections.

The metal profile strain relief device of the present invention (hereinafter referred to as 1 strain relief device).

) is that the lifting frame with the J key can be slid on one side of the correction frame with the guide key by an appropriate drive means.

The correction frame is rotatable by an appropriate drive means around the pivot point to the machine base.

The present invention is characterized in that at least one set of the above configurations is arranged.

Hereinafter, the strain relief device of the present invention will be explained using examples.

As shown in the second figure, an elevating frame 3 having a key hand 2 is slidably fitted into one side of a correction frame 6 having a guide key 5 by appropriate driving means.

The correction frame 6 is rotatably attached to the base 1 by appropriate driving means.

In this example, the hydraulic plunger cylinder device 4 as an appropriate driving means for making the lifting frame 3 slidable is located on the opposite side of the lifting frame 3 from the key 2! One end is fixed to the straightening frame 6, and the other end is pivotally connected to the correction frame 6.

In addition, a hydraulic plunger cylinder device as an appropriate driving means for making the correction frame 6 rotatable has one side connected to the base 1.
and the other is pivotally attached to one end of the correction frame 6, respectively.

In this example, such mechanisms are arranged symmetrically on the base 1.

For example, the strain relief device of the present invention configured as described above may be used as a fourth
To explain the case where the metal profile chucking mechanism is placed on one side as shown in the figure, first, the metal profile to be processed A
is inserted between the fixed jaw 13 and the movable jaw 14 and placed so that the strained part is located in the strain relief device of the present invention, and then the movable jaw 14 is lowered and the metal profile A to be processed is inserted into the fixed jaw. 13 as shown in Figures 6 and 7.

When the metal profile A1 to be treated, for example, a steel sheet pile, is bent outward, as shown in Figure 6, the - side abdomen 8 of the straightening frame 6 is applied to the outside of the steel sheet pile, and then □hydraulic The correction frame 6 is rotated to the left by the plunger cylinder device 7 for correction.

On the other hand, if the steel sheet pile is bent inward, the hydraulic plunger cylinder device 7 is driven to rotate the straightening frame 6, and the hydraulic plunger cylinder device 4 is driven to raise and lower the sheet pile, as shown in Figure 7. After sliding the frame 3 and locking the key 2 above the steel sheet pile A, the correction frame 6
is rotated to the right by the hydraulic plunger cylinder device 7 to correct it.

Similarly to the above, the strain on the rising portion on the left side of the steel sheet pile can also be corrected at the same time using the strain relief device of the present invention placed on the left side.

The above-mentioned operations are performed sequentially on each strained part to correct the distortion. If the chuck device 11 is fixed to the side of the chuck device 11 which moves on the guide rails 10 extending from left to right of the machine, it is very effective because the distortion of the rising portion can be corrected at the same time.

It should be noted that by using a suitable jaw 13, 14 or other fixing mechanism, it is possible to correct distortions in similar parts of H-shaped steel or other metal sections, and with just one set of mechanisms of the present invention, it is possible to correct distortions in a specific shape. It can also be used as a dedicated strain relief device for metal shapes.
If one pair or a plurality of pairs are arranged in a metal shape straightening machine as shown in the third figure, it is also possible to continuously straighten the strain by using the waist key 2 as a roller, which further improves efficiency.

Furthermore, the strain relief device of the present invention can be applied not only to strain relief but also to forming metal shapes.
