Aluminum material extruding machine

Abstract

The invention discloses an aluminum material extruding machine in the technical field of equipment manufacturing. The aluminum material extruding machine comprises a platform fixed to the ground. The platform is sequentially provided with a die base, an extruding cylinder, an extruding beam and an air cylinder from left to right. The die base is provided with a die. The extruding beam and a piston rod of the air cylinder are fixed. The die is fixedly connected into the extruding cylinder. The die base, the die, the extruding beam and the extruding cylinder are located on the same axis. The extruding cylinder comprises an inner layer and an outer layer. The outer layer of the extruding cylinder is connected with a vacuum pump through a flexible pipe. One end of the flexible pipe extends into an interlayer formed by the inner layer and the outer layer of the extruding cylinder. The vacuum pump is arranged on the platform. By the adoption of the extruding machine in the scheme, after the vacuum pump is started, air in the interlayer is pumped out to make the interlayer vacuum, the extruding cylinder does not dissipate heat easily, the cooling speed of aluminum materials is low, and the aluminum materials can be formed beneficially.

Description

technical field [0001] The invention relates to the technical field of equipment manufacturing, in particular to an aluminum extrusion machine. Background technique [0002] In recent years, due to the miniaturization and lightweight requirements of automotive air-conditioning equipment, the proportion of aluminum extruded products in heat exchanger tubes and hollow profiles has increased rapidly, and aluminum and aluminum alloy products account for more than 70% of extruded products. The development of aluminum alloy profile extrusion technology has therefore led to the development of modern extrusion technology. [0003] The extrusion process of aluminum alloy profiles is to put the aluminum alloy blank into the extrusion cylinder installed on the plastic forming equipment. The hole is extruded to obtain the required cross-sectional shape and size; during the extrusion process, the aluminum alloy is in a state of strong three-dimensional compressive stress in the extrusio...
