Title: Manufacture of square steel pipe
Inventor: ITAYA MOTOAKI
IPC: B21C37/15
Filed: 1994-06-06
Abstract: PURPOSE:To reduce the deformation of the cut section of a square steel pipe at low cost by specifying the whole drawing quantity of square forming, and specifying the total drawing quantity of the stands of half of the numbers or below or the drawing quantity of a single stand. CONSTITUTION:A square steel pipe 2 is attained by passing a round steel pipe 1B through a sizing roll 16, further, by passing it through reshaving rolls 17A to 17D and by forming it to a square. In a square forming process by this square forming roll group R1 to R4, the whole drawing quantity of the outer peripheral length of square forming expressed by Napierian logarithm is set to 1.5% or over. Also, out of total square forming stands, the total drawing quantity of continuous stands of half of the numbers or below is set to 70% of the whole drawing quantity or over, or the drawing quantity of a single stand is set to 50% of the whole drawing quantity or over to perform square forming. Consequently, the deformation of the cut section of a square steel pipe can be reduced without performing hot forming or a heat treatment.

IPC: C03B19/02
Filed: 1992-06-05
Abstract: PURPOSE:To prevent the generation of surface detects by imposing a glass gob on an extruding split die, pressing the glass gob with a punch to pour the high-viscosity glass into a die having a mirror-finished forming surface and to form an intermediate product, then removing a stem part. CONSTITUTION:Molten glass 9 is poured down into a casting mold 10. The slow cooling part forming the glass gob 11 forms a soft film. The glass gob 11 is taken out of the casting mold 10 and is imposed on the extrusion split die 2 imposed on the die 11. The punch 3 is then placed on the glass gob 11 and is pressed to pour the high-viscosity glass from the hole 16 of the extrusion split die 2 into the die 1. The section is bulged to a circular shape from the central part toward the outer peripheral part of the die 1 by the pouring and the displaced air is dissipated from the spacing between the die 1 and the extrusion split die 2 to the outside. The surface defect of the lens by the trapping of the air is prevented. After the high-viscosity glass is filled into the die 1, the glass is cooled while the punch 3 is held placed thereon. The stem 18 is ten cut off from the formed intermediate product 17 of the lens, by which the lens 19 is obtd.
