Introduction and use of aluminum profile extrusion press machine plant line

Aluminum extrusion machine is divided into two kinds of forward extrusion and reverse extrusion, aluminum production equipment at present most of the use of forward extrusion machine, the scientific principle is the principle of hydraulic press, to analyze from the structure of the extrusion machine. We usually divide the extruder into three parts: master cylinder, middle plate (extrusion barrel), extrusion rod.

Master cylinder is a hydraulic equipment, hydraulic oil pressure to the small piston, through large piston travels forward extrusion rod, will be after heating of aluminum rod extrusion barrels, after reaching the exhaust pressure extrusion barrels back exhaust, go forward with the mold cavity, after reaching the material pressure, extrusion rod and forward to the aluminum extrusion barrels into mould tap hole, aluminum alloy by die slowly out of shape.

The vertical and transverse levelness of the guide rail of the frame should not exceed 0.05/1000; Aluminum extruder installation or large, medium repair, must pay attention to the parallelism of the two guide rails: in the full length of the guide rails should not be installed accuracy detection and adjustment, to achieve the accuracy of more than 0. LMM degree standard or design requirements, so as to improve the accuracy of aluminum extruder.

When there is precision, how to improve the speed of aluminum extrusion machine? According to the tonnage of the extruder, the complexity of the shape of the die section, the heating temperature of the aluminum rod and other factors to make appropriate adjustments, so that the speed can be improved to some extent.
