Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a work supporting table in a scoring machine having a stainless plate folding curve.

[Prior Art] When a stainless thin plate for processing is placed on a support table and positioned, and when a folding curve is cut and formed on the upper surface of the stainless thin plate by the ruled blade as the ruled blade holder reciprocates left and right, In many cases, the cutting depth is erroneously set to be larger than the thickness of the thin flat plate to form a cutting trace on the upper surface of the supporting table along the sliding line of the scoring blade to damage the upper surface. Further, the stainless steel plate forms a ridge on the lower surface by the cutting pressure by the cutting blade, and a dent mark is formed on the upper surface of the table along the sliding line of the scoring blade through the ridge to damage the upper surface. To deal with such damage, a very complicated repair method is used in which the table 2 is lifted with bolts 15, a thin plate is laid on the lower surface of the table 2 and the upper surface of the lifted table 2 is polished with paper to provide a flat surface. It was being appreciated. In order to repair the above damage, the bolts 17 are removed to separate the table front portion 18 from the table body as shown in FIG. 4, and the front portion 18 is replaced with a new one. This method has a problem that the thick, heavy and expensive table front portion 18 is wasted, and that labor and time are required.

[Problems to be Solved by the Invention] The purpose of the present invention is to repair the damage of the upper surface of the table 2 by the ruled blades easily and quickly, reduce the repair material, and significantly shorten the repair cost and repair time.

[Means for Solving Problems] The present invention for achieving the above-mentioned object is to provide a flat plate supporting table for processing on a machine frame, and install a ruled blade holder on the upper part of the table so as to be reciprocally slidable in the left-right direction. Then, in a scoring device in which an elevating and lowering presser for fixing the flat plate is provided immediately after a horizontal reciprocating sliding line of a scoring blade which is vertically supported by the holder, a horizontal direction is provided on an upper surface of the supporting table. Work support table in a stainless plate folding curve scoring machine in which a shallow groove that can fit the strip is formed along the line before and after the reciprocating sliding line. The upper surface of the strip is in the same plane as the upper surface of the table. It is constituted by the work supporting table in the stainless plate folding curve scoring machine described in the above invention, which is supported and can be detachably fitted.

[Operation] Therefore, when the strip 3 is fitted in the shallow groove 4 on the upper surface of the support table 2, the upper surface of the strip 3 and the upper surface of the table 2 are supported in the same plane. In this state, the processing flat plate 1 is placed on the table 2, and after positioning, the vertically movable presser foot 5 is lowered immediately after the sliding line L of the ruled blade 6 so that the flat plate 1 is placed on the upper surface of the table 2. After pressing and fixing, in this state, the ruled blade 6 is lowered by a predetermined distance to move the ruled blade 6 to the flat plate 1.
By descending to a predetermined cutting depth position and sliding the scoring blade holder 7 to the left, the folding curve 8 by the cutting groove can be scribed on the upper surface of the flat plate 1. After that, the operation of raising the ruled blade 6 and sliding it to the right to return it to the original position and further lowering the blade 6 to deepen the cutting depth and sliding to the left is repeated a plurality of times to obtain a predetermined depth. The folding curve 8 can be marked. At that time, if the cutting depth is set incorrectly and is set to be larger than the thickness of the flat plate 1, the scriber blade 6 cuts the flat plate 1 along the line L and cuts the upper surface of the lower strip plate 3 to form a cutting scratch on the upper surface. To do. Even if the cutting depth is a normal depth, a ridge is formed on the lower surface of the flat plate 1 by the cutting pressure, and the cutting pressure is transmitted to the upper surface of the strip 3 through the ridge, and the dent mark due to the cutting pressure is formed on the upper surface. In order to form the above, the unevenness due to the concave streak is formed on the upper surface of the strip plate 3, and unevenness is generated in the upper surface level of the new flat plate 1 placed thereon, or a space due to the streak is formed on the lower surface of the flat plate 1. Occurs,
Since the flat plate 1 is not stable in the vertical direction, the cutting depth of the folding curve 8 by the scriber blade 6 becomes uneven, or the flat plate 1 is cut. In order to prevent this, the strip plate 3 with the above-mentioned striations in the shallow groove 4 is removed from the shallow groove 4, and a new strip 3 is fitted into the shallow groove 4 and replaced to repair the above-mentioned striations. can do.

[Embodiment] A machine frame 9 is provided with a table 2 for supporting a work for bending curves, that is, a stainless flat plate 1 having a thickness of about 2 mm or less, and a ruled blade holder 7 is horizontally guided on the upper side of the table 2. Arranged so that it can slide back and forth along the guide 10,
The ball nut 12 provided on the holder 7 is screwed into the ball screw 11 installed in parallel with the guide 10 to form a ball screw.
The holder 7 is slid back and forth by rotating 11 forward and backward. A ruler blade 6 is supported on the holder 7 so as to be adjustable up and down, and a trailing edge holding tool 13 of the flat plate 1 is provided in a front-rear direction adjusting device 14 behind the sliding line L of the ruler blade 6, and Immediately after L, a lifting / lowering presser 5 for fixing the flat plate 1 is arranged to form a marking device for the stainless flat plate 1. A shallow groove 4 (for example, a depth of 1.5 mm and a width of 35 mm) is formed in the upper surface of the table 2 in parallel with the line L. The plate 3 is detachably fitted, that is, replaceable. The strip 3 has a thickness of 1.5 mm and a width of 35 mm, and in the fitted state, the upper surface of the table 2 and the upper surface of the strip 3 are aligned or supported in the same plane. However, shallow groove 4 and strip 3
The above dimensions do not have to be limited and may be appropriately designed. The sliding line L is not a mark on the table 2. In the figure, reference numeral 15 indicates the machine frame 9 and the table 2 above.
And fixing bolts, 16 is a bolt head receiving hole.

[Effect] Since the present invention is configured as described above, the folding flat plate stainless steel plate 1 fixed on the support table 2 is mistakenly used for the ruled blade 6.
By cutting with the above, a cutting striation is formed on the upper surface of the table 2, or a concave striation on the upper surface of the table 2 due to the cutting pressure of the flat plate 1 is exchanged with the strip plate 3 to make it extremely quick, simple and inexpensive. There is an effect that can be repaired.
