Abstract
PURPOSE: To prevent the failure during cold working and lower the cost of manufacture by combining 6 pieces of small nib pieces of a trapezoidal shape to form a nib of a regular hexagonal outside circumference, fitting a ring of a regular hexagonal inside circumference and a circular outside circumference to the outer side thereof and further fitting a die case to the outer side thereof.
CONSTITUTION: Six pieces of small nib pieces 1 of an isosceles trapezoidal shape having legs 7, 8 of the same length and an upper bottom 9 shorter than a lower bottom 10 are combined in contact with each other to form a nib 2 of a regular hexagonal shape in outside and inside circumference. A ring 3 of an inside circumference of a regular hexagonal shape similar to the outside circumference of the nib 2 and a circular inside circumference is fitted to the outer side thereof, and further a circular die case 5 having an inside circumference similar to the outside circumference of the ring 3 is fitted to the outside circumference thereof. Here, the nib of a regular hexagonal shape are sometimes fitted in two steps, inward and outward in an axial direction and in some cases, the ring is divided to two. This die is used for nut formers and bolt formers.
