The invention belong to the technical field of aluminum
alloy profile and concretely relates to a manufacturing method for slide rail hollow profile for
robot arm movements with aluminum
alloy replacing steel. The manufacturing method comprises first, analyzing steel connection member motion and
stress conditions, second, selecting aluminum-
alloy material, third, designing hollow profile, fourth, simulating aluminum profile connection member motion and
stress conditions by a computer to determine whether the hollow profile meets demands, fifth, selecting an extruding
machine and designing an aluminum alloy hollow profile connection member via a die, sixth,
casting aluminum alloy
ingot, seventh, extruding aluminum alloy hollow profile connection member and conducting online
quenching, eighth, conducting aluminum alloy hollow profile connection member tension extension and aging treatment, ninth, sampling and checking the aluminum alloy hollow profile connection member, and tenth, hardening and packing the aluminum alloy hollow profile. Motion and
stress conditions of the aluminum alloy hollow profile connection member can be simulated by the computer; strength and
plasticity meet use requirements; and hollow profile can be manufactured in batches by the use of the method.
