Abstract

PURPOSE:To forcibly carry out the slug generated due to punching by forcibly blowing the air to the bush inside the die. CONSTITUTION:The slug that the material to be worked is punched is entered inside the die bush. In this time, the punched slug is carried out from the die by supplying the air from the outside, and forcibly supplying the air from the hole slantingly bored at the die bush. The stream of the air is made so as to become downward by setting the angle of the hole to be bored to about 10-80 deg.. The diameter of the hole of <=1mm is effective, and the air pressure 0.5-5kg is suitable. And if the effect is not enough with one hole number, the enough effect can be shown by providing plural numbers of holes.

る。In the above-mentioned prior art, punching scraps are deposited on the upper surface of the die as shown in FIG. 2 (a). Further, as shown in FIG. 2 (b), punched dust is clogged on the inner surface of the die. However, this has led to damage to the mold. According to the present invention, air is forcibly wiped from an obliquely opened hole on the inner surface of the die to reliably carry out the waste in the die.

る効果を発揮する。Embodiments of the present invention will be described below with reference to the drawings. FIG. 3A shows a state in which the workpiece is punched by a pair of upper and lower blades. The punched dust enters the die bush, and at this time, air is forcibly supplied from the outside of the mold to carry the dust down. The die bush is provided with an obliquely drilled hole. The angle of the hole is set within 10 ° to 80 ° so that the air flow is downward. If it is set out of this range, the effect of carrying out scraps is lost. If the effect is not sufficient when the number of holes is one, it is sufficient to install 2, 3, 4 holes evenly around the entire circumference as shown in Fig. 3 (b). It can be effective. In addition, in order to obtain a greater effect, 1 ° to the relief hole
The effect is increased by performing the 2 ° taper process. As a result, there are no scraps in the mold, and the waste is surely carried out of the mold, so that no trouble occurs. Particularly, this method is effective in the shape of a small hole of φ1 mm or less, and also exhibits a sufficient effect in high-speed press working.
