Abstract
This design is about the three-roller symmwtry rolling machine,mainly calcats the up and down roller and the decelerator.
Roll trigger a sheet metal bending roll into the cylindrical, arc or other shape the universal equipment. According to the principle of into round three, use of work roll change and the relative position of the rotary motion to produce continuous plastic deformation plank, scheduled for the shape of the workpiece. In order to improve the efficiency of the roll triggers, improve the machining precision of the products, reduce labor intensity, to improve the working conditions of the sheet metal, usually by lateral table, auxiliary operation machinery, bracket platform, as well as supporting groove and auxiliary equipment. Roll trigger as a special machine, it in the industry foundation processing occupies an important position. All steel cylinder, forming for almost all roll trigger roller system with. The products are widely used in the boiler, shipbuilding, petroleum, chemical industry, carpentry, metal structure and other mechanical manufacturing industry.
During the front process of the design,the rolling machine`s structucre design and the analysis of strength are described. The rolling machine` structure is three-roller symmetry. Pressure provides pressure under owing structure the above-average roller , the roller does revolution sport under two , sheet material provides moment of torsion to roll of system.It has a series of advantages such as simply structure,small volume,light weight,economical and so on.YZ type YZ-160L-6 motor is selected as the power source,which adapts situation such as slience quenching and light reverse velocity.
The last part of the paper is ahout decelerator which is choosing triple expanding columm gear constiuction .The material of gear is 40Cr which has been hardening surface.The gears, axes, keys, bearings are checked, so to confirm this design is practical
