Abstract

PURPOSE:To perform the clearance adjustment of a metal die quickly and accurately by finding the deformation of a pad due to the pressure by pressing the work with the metal die in the state of fitting the pad into a piercing part after executing a pressure treatment and piercing process on the work. CONSTITUTION:The pad 14 caused as the slug is fitted into each hole 12 after piercing plural holes 12 by using a punching press on the work 10 subjected to a pressure treatment by using the metal die to be measured. The deforming quantity or projecting quantity of the pad 14 due to the pressing is measured with the pressure treatment of the work 10 in which the pad 14 is fitted between the lower die 16, upper die 18 and the clearance variation of the dies 16, 18 is found from this measuring value. In this way the clearance adjusting work of the metal die can be performed quickly and accurately.

When manufacturing molds such as press molds, clearance adjustment work is performed as a finishing work in mold manufacturing. Conventionally, when adjusting the clearance of the mold, a clearance sheet was used to measure and determine the clearance of the mold, but with the method using a clearance sheet, it is not possible to measure areas with excessive clearance. In some cases, it may not be possible to measure the clearance at the corner of the mold, so the mold surface is coated with paint, etc., and the molds are aligned, and the worker can estimate where the paint has peeled off due to mold interference. The cutting process was repeated repeatedly.

Note that the hole in the workpiece 10 may be made before drawing, but if the hole is made in the workpiece 10 before drawing, the hole diameter may be deformed due to the elongation of the material of the workpiece 10 during drawing. If holes are made in the formed workpiece 10 using a punching press, the distance between each hole 12 can be shortened, and the material will not be stretched during drawing, so it will be more accurate and the tolerance will be better. Measurement data can be obtained. In addition, when drilling holes in the workpiece 10 before drawing forming, the distance between the holes 12 should be Q≧10d and the hole diameter d≦5t so that cracks due to elongation do not occur when press forming the workpiece 10. is desirable.

The pad 20 configured in this way is inserted into each hole 1 of the workpiece 10.
2, as shown in FIG.
If pressure is applied by the lower mold 16 and the upper mold 18, the pad 20 in the area where the clearance is close to 0 will be more deformed by the pressure of the upper mold 18, and the cylindrical body 20B will be buried in the hole 12. On the other hand, in the pad 20 at a portion where the clearance is large, the amount of deformation of the cylinder body 20B is small. Therefore, by determining the amount of deformation of the pad 20 and cutting the wall surface of the upper mold 18 according to this amount of deformation, the clearance of the upper mold 18 can be made uniform.

In addition, in this example as well, workpiece 1 is
The hole at 0 may be made before drawing with a die, but since the drawing of the die causes elongation of the material in the workpiece 10 and changes the hole diameter, By drilling holes, the distance between the holes 12 can be shortened, and since the material does not stretch during drawing, more accurate measurement data can be obtained.

The material of the pad 20 is preferably a soft metal or plastic so as not to damage the mold during press molding, and should be easily crushed and not restored to its original state by pressure. In addition, the shape of the pad 20 is such that it does not protrude onto the workpiece 10 when crushed.
It is preferable to provide a sharpening part as a hat shape.
Furthermore, when fitting into the hole 12 of the workpiece 10,
It is desirable that the outer diameter of the base 20A be slightly larger than the hole diameter of the hole 12 to prevent it from falling.
