Molding bed forging method for barrel with side connection pipe seat and die

Abstract

The invention provides a molding bed forging method for a barrel with a side connection pipe seat and a die and particularly relates to the technical field of forging. A first barrel comprises a firstbarrel body and a first pipe seat, and the outer wall of the first barrel body is connected with the first pipe seat. The molding bed forging method comprises the steps that the first barrel body isprepared, and a first protrusion is manufactured on the edge of one end of the first barrel body; the first protrusion is squeezed to make the side wall of the first barrel body to protrude outwards to form a second protrusion; and the second protrusion is squeezed to be manufactured into the first pipe seat. According to the molding bed forging method for the barrel with the side connection pipeseat and the die, an integrated barrel forge piece with the side connection pipe seat formed with the molding bed forging method avoids welding lines fundamentally, and thus the service stability of abarrel component with the side connection pipe seat is ensured. Furthermore, a forging assembly line is reserved to the maximum degree, the comprehensive mechanical performance of the forge piece isimproved, and thus the requirements, such as the requirement that container equipment in the nuclear electrical field is subjected to nuclear radiation in long term, are met.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a tire mold forging method and a mold for a cylindrical body with a side socket. Background technique [0002] For large-scale heavy equipment, it is often necessary to have a cylinder with a side connection, that is, the tube base is connected to the side wall of the cylinder. Large-scale heavy equipment is often used in special environments, such as nuclear power, hydropower, etc., so there are very high requirements for the parts of large heavy equipment. In this case, it is necessary to avoid welding the cylinder structure and The structure of the pipe seat is connected to avoid the influence of the weld seam on the stability of the part. In addition, there are often other special requirements for the part, such as the wall thickness of the pipe seat is thicker than the wall thickness of the cylinder. Manufacturing presents great challenges. [0003] Specifically, for examp...
