An aluminum profile isothermal extrusion system and extrusion method thereof

Abstract

The invention discloses an aluminum section bar equal-temperature extrusion system which comprises an extrusion barrel (1), an extrusion oil cylinder (2) and an aluminum section bar outlet temperature detecting mechanism, wherein a piston rod of the extrusion oil cylinder (2) is arranged in a material extruding cavity (3) in a penetrating mode, and is connected with an extrusion pad (4); the right end part of the extrusion barrel (1) is equipped with a pad mould (5); a through slot which communicates with the material extruding cavity (3) is formed in the pad mould (5); the aluminum section bar outlet temperature detecting mechanism comprises a perpendicular air cylinder (6) and a temperature sensor (7); the perpendicular air cylinder (6) is arranged on the right end part of the extrusion barrel (1); the bottom of a piston rod of the perpendicular air cylinder (6) is equipped with the temperature sensor (7); and a cooling channel (8) is further arranged on the cylindrical surface of the extrusion barrel (1). The aluminum section bar equal-temperature extrusion system has the beneficial effects that: the structure is compact, the aluminum section bar outlet temperature is efficiently controlled, aluminum section bar production efficiency is improved, and product quality is guaranteed; and the production process is simple.

Description

technical field [0001] The invention relates to the technical field of isothermal extrusion of aluminum profiles, in particular to an isothermal extrusion system of aluminum profiles and an extrusion method thereof. Background technique [0002] At present, with the advancement of aluminum extrusion technology and the rapid development of the national economy, the application of aluminum profiles in transportation, aerospace, industrial machinery, electronic equipment and other fields is increasing year by year, especially in my country's transportation industry towards lightweight and high-speed With the development in the direction of environmental protection, transportation vehicles such as subways, high-speed trains, light rails, and double-decker buses gradually adopt aluminum profiles. The length of aluminum profiles for transportation is often up to 10-30m. There are high requirements for the shape and size accuracy of aluminum profiles, and the uniformity of structure...

AI Technical Summary

Problems solved by technology

In order to prevent the profile outlet temperature from being too high, a relatively low extrusion speed is generally adopted, which limits the extrusion production efficiency

At the same time, under constant-speed extrusion conditions, the temperature and deformation of the metal are extremely uneven, which easily leads to quality defects in the size, shape, structure and performance of the product.
