Aluminium alloy pressure-maintaining extruding device easy to cool and extruding method thereof

Abstract

The invention relates to the technical field of aluminium alloy extruding devices, in particular to an aluminium alloy pressure-maintaining extruding device easy to cool and an extruding method thereof. The extruding device comprises a plunger type feeding assembly, a three-way piece, a material storage assembly, a moulding mould and a pressure-maintaining blanking assembly; the plunger type feeding assembly is provided with a supplying flow channel, a feeding flow channel, a feeding piston and a shutoff valve; the feeding piston is arranged in the feeding flow channel in a sliding manner; the supplying flow channel is communicated with the feeding flow channel; the three-way piece is provided with a three-way flow channel; the material storage assembly comprises a material storage cavity and a material storage piston; the material storage piston is arranged in the material storage cavity in a sliding manner; the moulding mould is provided with a moulding flow channel; the pressure-maintaining blanking assembly comprises a blanking mould, stop covers and driving devices; the blanking mould is provided with two shaping flow channels; the pressure-maintaining blanking assembly and the moulding mould are arranged in a relatively reciprocating sliding manner so that the two shaping flow channels are alternately communicated with the moulding flow channel; the moulding mould is provided with pressure-maintaining material stop parts. According to the aluminium alloy pressure-maintaining extruding device easy to cool and the extruding method thereof, continuous high pressure intensity can be provided for a material; the mechanical properties of a product are improved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy extrusion devices, in particular to an easily cooled aluminum alloy pressure maintaining extrusion device and an extrusion method thereof. Background technique [0002] Most of the existing extrusion devices are continuously fed by the screw feeding device, but the pressure provided by the screw feeding device is relatively small. Generally, the maximum pressure on the material is 500MPa~650MPa, and it cannot provide higher pressure. [0003] Therefore, it is necessary to provide an aluminum alloy pressure maintaining extrusion device and an extrusion method thereof that can provide higher pressure. Contents of the invention [0004] The purpose of the present invention is to provide an easy-to-cool aluminum alloy pressure-holding extrusion device for the deficiencies of the prior art, which can provide continuous high pressure to the material and improve the mechanical properties of ...
