Problems solved by technology

In the process of production and use, the cavity is a vulnerable part. Because the materials selected for the cavity are expensive and have a short lifespan, the production cost increases
In most cases, the damage of the cavity is caused by the deformation or cracking of the stopper, which causes the damage of the entire cavity and needs to be replaced as a whole

Abstract

The present invention relates to shaped section extruding apparatus, and is especially one kind of combined continuous extruder cavity. The cavity consists of panel including sealing plane and feeding port, bottom plate, material stoppers as independent parts embedded to the cavity, and mold. The cavity in the combined structure with embedded material stoppers may have material stoppers of different material for greatly raised load bearing capacity and may have the damaged material stopper replaced without need of replacing the whole cavity. The cavity bottom plate is so designed that mold may be installed, and this can lower the height of the cavity obviously and saving material for the cavity.

Description

Technical field: [0001] The invention relates to equipment for manufacturing copper and aluminum busbars, ladder bars, copper flat wires, various bars and other nonferrous metal products by continuous extrusion. Background technique: [0002] The cavity of the existing continuous extruder is composed of several parts, such as a sealing surface, a material blocking block, a feed inlet, a billet flow channel, and a cavity for installing a mold, and these parts are a complete part. In the process of production and use, the cavity is a vulnerable part. Since the material selected for the cavity is expensive and has a short lifespan, the production cost increases. In most cases, the damage of the cavity is caused by deformation or cracking of the stopper, which causes damage to the entire cavity and needs to be replaced as a whole. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned disadvantages and provide a combined continuous...
