Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to the technology of measuring measures in machine tools, particularly to the technology of measuring 31 measures in punch dies of presses.

BACKGROUND ART Conventionally, machine tools have been equipped with measuring scales, etc. to determine the mounting position of the workpiece and the form of pressurization. A scale is provided to determine the location of the hole to be drilled.

Of course, it is also possible to place the workpiece, such as a sheet metal, on a scribing table and use an index finger to make the marks, but the present invention does not use this method, but instead relates to continuous drilling.

Going back to the previous section, in the right-angled ruler-shaped Aributan, one end of the two Benmin is tied A to make them orthogonal in the vertical and horizontal directions. From the 0 point in the middle, cut out a semicircle of a cylindrical punch die (the IJ/L receiver is a mold), and from the end where the horizontal scale is cut out, The diameter of the circle (for example, 28 mm) is calibrated, and the vertical part is perpendicular to the side of the circular protrusion of the horizontal part, and the outer intersection point of the horizontal part is set to 0. There are 11 points.

Now, for example, when punching a hole at a distance of 35 mm horizontally and 20 mm vertically from the end of the sheet metal using a punch die with a diameter of 28 mm in the row, the notch of the member next to the hit member is inserted into the punch die. Insert it, move the vertical member to the 35n1m position on the scale and fix it, align the vertical hit rate above it and fix it, then continue from the 0 point of the vertical member to 2on1m. Then, by aligning the horizontal hit points to that amount and fixing the size, by touching the sheet metal to the vertical and horizontal hit points 4J and using tri/l,
Holes can be drilled at the required 35 x 20 mm locations and can be made one after another in the same manner.

In this conventional method, the semicircular notch part of the punch die is separated from the punch die when the horizontal distance is two times longer than the diameter of the punch die (28 mm or more in the example). Align the vertical center line with the 0 point on the horizontal scale, and align or parallel the corner (1t1 corner) of the workpiece in the press for the ruler's reliability. This is because when you take a horizontal division, you can immediately continue the vertical number I [eight] from the position of the intersection on the 1 side where the horizontal division and the vertical division meet.

However, when using this conventional right-angled ruler, when drilling holes at a horizontal spacing of less than the diameter of the punch die, or more than 28 mrη according to the precedent, they are completely unable to complete the above-mentioned marking work. - I have to rely on others.

In the present invention, the width of (within the inner diameter of the punch die)
Not only can the hole be positioned easily and accurately, but it is also easier to attach to the die set than the conventional right-angled ruler-shaped contact part, and it is easier to attach to the die set than the conventional right-angled ruler-shaped contact part. 4. It is superior in terms of ease of installation. It is a creation of a ¥1 measuring instrument.

Unpacking of the Invention The present invention involves vertically cutting the central part of a rectangular metal plate from one long side by the width of the diameter of a punch die, and placing the tip of the notch on the surface of the plate at a point 0 and -. 4 is provided along the notch, and furthermore, a semicircle with a diameter between the two 0 points is provided as a notch at the front of the insertion part, and a vertical center line of the insertion part is placed on the other longitudinal side. To set the matching zero point, expand the scale horizontally and horizontally, and attach the engagement piece that can be detachably attached to the die set to the bottom of the flat plate.
