Abstract
PURPOSE: To easily make a saddle-shaped body light and thin by beforehand adjusting the thickness of a blank material to be drawn between upper and lower dies, and providing a protruding strip having slopes on the inner side on the flat face of the circumferential edge part of the upper die.
CONSTITUTION: A blank material of a required thickness and a rectangular section is cut to a suitable length, is heated and is placed between upper and lower dies 20, 21. Both dies are then pressed to plastically deform the blank material. A projecting strip 24 having a slope 22 on the inner side and a perpendicular face 23 on the outer side is so provided to the flat part formed in the circumferential edge part of the upper die 20 as to make a round. The projecting strip 24 is formed around the fin 31 of a semifinished product 30' at the forming, by making round the groove 32 and at the same time the flatness of the flat face 34 of the upper face circumferential part of a saddle body 30 is obtained accurately; in addition, the under fill in the inside wall part 35 of the circumferential edge is prevented. After the forming, the fin 31 is cut off along the groove 32, whereby the finished product is obtained.
