DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a work table in a corner shear for notching.

(Prior Art) Conventionally, in a work table in a corner shear, a first guide portion extending in the front-rear direction is provided for positioning the plate material in the front-rear direction, and the first positioning portion is provided with the first positioning portion. A stopper is provided so as to be movable in the front-rear direction and fixed, and a second guide portion extending in the left-right direction is provided for positioning the plate material in the left-right direction. The second guide portion has a second guide portion. The positioning stopper was provided so that it could be moved and fixed in the left-right direction. Therefore,
The first positioning stopper is positioned at a predetermined position in the front-rear direction on the first guide portion, and the second positioning stopper is positioned at a predetermined position in the left-right direction on the second guide portion. Then, the plate material is positioned at a predetermined position on the work table by bringing the appropriate end faces of the plate material into contact with the first positioning stopper and the second positioning stopper.

(Problems to be solved by the invention) However, in the work table of the corner shear as described above, the moving range of the first and second positioning stoppers is limited within the work table. In some cases, it is not possible to position the plate material at a predetermined position on the work table by appropriately bringing the positioning gauge or the second positioning stopper into contact with the end surface of the plate material. Therefore, when the plate material is positioned by scribing or the like, there is a problem that the plate material positioning accuracy is poor and precise notching cannot be performed.

Further, when the plate material is relatively large, the end portion side of the plate material that is not supported by the work table tends to bend, and the entire plate material cannot be sufficiently supported. Therefore, there is a problem that precise notching processing cannot be performed similarly to the above-mentioned problems.

[Structure of the Invention] (Means for Solving the Problems) In view of the conventional problems as described above, the present invention provides a work table that includes a notching portion that performs notching processing on a plate material and that supports the plate material. In a work table in a corner shear provided with a groove for guiding the positioning stopper for positioning the plate material in a positionally adjustable manner, a work support connected to the groove and provided with a groove for positioning the positioning stopper, The work table is detachably attached.

(Operation) In the above structure, the work support is detached from the work table, and the positioning stopper is positioned at a predetermined position on the work table. Then, the plate material can be positioned at a predetermined position on the work table by bringing an appropriate end surface of the plate material into contact with the positioning stopper.

When the plate material has a special shape, or when the plate material is relatively large, the work support is first mounted on the work table. Further, the positioning stopper is appropriately moved through the positioning stopper, the guide portion of the work table, and the guide portion of the work support to be fixed at a predetermined position on the work table or the work support. The plate material can be positioned at a predetermined position on the work table by being able to abut the positioning stopper on an appropriate end surface of the plate material.
