Abstract

PURPOSE: To produce the cone with good accuracy in a short work period by bisecting a metal straight pipe to trough-form bodies and forming a torus-form body from these.
CONSTITUTION: A metal straight pipe is bisected in its lengthwise direction to trough-form bodies 1 of semicircle in section. Next, the trough-form bodies 1 with their opening side being brought to the outer side are hot or cold bent to arc-form bodies 2. Next, a plurality of the arc-form bodies 2 are connected by welding to a torus-form body 3. Next, the torus-form body 3 is bisected circumferentially to the annular bodies A, B of the same shape of 1/4 circular form in section. Next, extension parts m, n are connected to the both sides of the annular bodies A, B, whereby these are formed to a fannel shape to provide the cone C.
