Abstract

PURPOSE: To lower cost and produce the captioned insert inexpensively by cold or warm forging a heat-resisting steel blank of disc form or the like having the specific amount of carbon to an aporoximately concave shape in section thence opening a hole in the bottom.
CONSTITUTION: A heat-resisting steel blank 1 of disc- or circular cylindrical form of carbon content 0.06% (preferably 0.04%) or less is inserted into a die 5 and is cold or warm pressed by a punch 6 and counter punch 7, to be made into the insert member 4 of a disc shape assuming an approximately concave shape in section whose inside bottom surface 2 inclines, thence a hole 3 is opened in the bottom by arbitrary means such as of cutting, drawing and electric discharge machining. Providing a torus-form protrusion on the outside edge of the bottom is equally well. In this way, the swirl type combustion chamber insert for diesel engines is produced inexpensively without requiring conventional intricate processes and time.
