Embodiment 2
[0044] This embodiment is a method for preparing an aluminum alloy handrail with a reinforced structure, comprising the following steps:
[0045] 1) Preheat the extrusion barrel of the extrusion molding equipment to 450°C-460°C, heat the aluminum rod evenly to 480°C-500°C, feed the aluminum rod into the extrusion barrel of the extrusion machine, and extrude Slow and uniform extrusion in the process, the extrusion speed is 2-3m / s, the uniform pressure is between 6-8 Mpa, the aluminum profile is extruded through the outlet of the extrusion die, and the outlet of the extrusion die is The shape matches the cross-sectional shape of the column product; the aluminum profile is cut, the outer surface of the cut workpiece is sandblasted, the cut workpiece is hung on the mounting frame of the sandblasting machine, and steel shot is used for sandblasting, and then the The suspended cut workpiece is hung upside down and then sandblasted again. After the sandblasting is completed, use a bl...

Abstract
The invention discloses an aluminum alloy handrail with a reinforced structure and a preparation method thereof. The aluminum alloy handrail includes a column, an upper limit ring seat and a lower limit ring seat. The upper limit ring seat and the lower limit ring seat have the same structure, and the center A snap ring is provided, and the top frame plate and the bottom frame plate of the carriage are respectively provided with mounting rings. The bottom end of the mounting ring is provided with a waist-shaped chute inward, and the inner end of the waist-shaped chute is provided with a circular lock groove. The outer side of the shaft is provided with screw joints and fastening grooves, and the upper and lower limit ring seats are respectively provided with turning grooves. The rotation in the turning grooves is limited by a rotating shaft with an end. The top of the rotating shaft is fixed with a waist-shaped lock block, and the side ends of the rotating shaft A fastening hole matched with the fastening screw is provided. The invention has rich functions. In addition to being used as a handrail, the column can be threaded with cables and safety ropes to facilitate the layout of the compartment circuit; at the same time, a built-in low-temperature heater can heat the column, which can improve the grip of passengers when the temperature is low. , especially the comfort of holding for a long time.
Description
technical field [0001] The invention relates to the technical field of aluminum alloy products, in particular to an aluminum alloy handrail with a reinforced structure and a preparation method thereof. Background technique [0002] The aluminum and aluminum alloy processing industry has entered a new period of rapid development, the application of aluminum is more and more extensive, and the transportation industry has become the largest user of aluminum. Aluminum is the material of choice for lightweighting, and it will inevitably partially replace steel and become an important basic material for various sectors of the national economy and all aspects of people's lives. Urban rail train is a fast and large-capacity rail vehicle running in the city. It has a superior ability to dredge passenger flow. The interior decoration and equipment of the vehicle are arranged according to the passenger flow. In order to improve passenger capacity and adapt to the characteristics of sh...
