Problems solved by technology

When the steel pipe is hot-extruded by this process device, there will always be a small section of the steel pipe billet remaining in the extrusion cylinder and cannot be extruded to become "residual waste", which generally accounts for 5-8% of the steel pipe billet, thus causing Great waste of expensive raw materials

Abstract

The hot extruded steel pipe blank tail mat heating and conveying apparatus includes one heating furnace with horizontal tracks inside the hearth and penetrating doors, one superposing material frame before the feeding door of the heating furnace, and one vertical material pushing oil cylinder and one horizontal material pushing oil cylinder. The superposing material frame consists of one upper plate with tail mat loading and unloading hole, one lower plate with oil cylinder piston rod lifted hole, and tail mat surrounding bars between the upper plate and the lower plate. The hot extruded steel pipe blank tail mat heating and conveying apparatus can convey tail mats into the heating furnace safely accurately in order and heat the tail mats, and has compact structure, high production efficiency and other advantages.

Description

technical field [0001] The invention relates to a material conveying device in the hot extrusion production process of steel pipes. Background technique [0002] Hot extrusion steel pipe is one of the more mature steel pipe production methods at present, especially for high-quality, high-demand, high-value stainless steel and alloy steel pipes used in special industries are basically produced by this method. The process device of hot extrusion forming steel pipe is generally composed of an extrusion cylinder, an extrusion die installed at the front end of the extrusion cylinder, and then sequentially loaded into the extrusion cylinder with a glass lubricating pad with a central hole, a steel pipe blank, and an extrusion pad. , supporting pressure on the rear end face of the extrusion pad, and its center is composed of an extrusion rod that can pass through the extrusion pad, steel pipe blank, glass lubricating pad and core rod of the central hole of the extrusion die. When ...
