Title Design of large aluminum castings poured
riser cutting machine worktable
Abstract
With the development of the mechanical manufacturing industry ， manufacturing
accounts for a large casting status has improved significantly.In the defense, aerospace,
shipbuilding, transportation, and many other areas plays a big role.At the same time
large castings poured riser cutting problems to a certain extent, restrict the development
of it.The current domestic large castings poured riser cutting basic using artificial cut，
There is a large labor intensity and low efficiency.Under the condition of the proposed
design of large castings poured riser cutting machine tools
This article mainly includes the large aluminum alloy castings poured riser cutting
machine workbench,this machine adopts the gantry frame type machine tool structure,
the workbench part main reference to design the planer, milling machine
workbench.Workbench is mainly composed of artifacts bearing parts - work platform,
the horizontal turning parts - guide rail, gear - ball screw pair, the power source - motor,
the overall support - bed, etc. This paper was carried out the design of lathe bed base and
the guide rail, actuator ball screw pair, drive servo motor and other standard parts
selection, and do the necessary checking, ensure the parts on the strength and stiffness
meet basically the requirements.
The machine table parts weighing about 10 tons, about 20 tons of lathe bed base, gross
weight around 30 tons. Maximum capacity of 15 tons of stroke, 3500 mm, maximum
speed 4000 mm/s, the minimum speed of 40 mm/s.
Key Words Machine tool workbench drive
