The mild steel plate Properties are 2 Youngs Modulus E207GN m Elastic limit yield stress σ y 515MN m 2 Poissons ratio034 Given data from the specification of the machine 22 The plate thickness t1mm Upper roller diameter du50mm Lower roller diameter dl50mm Lower rolls centre distance 2f120mm Theplate rolling speed v 55ms. In this post the calculation of the force capabilities of symmetrical three-roll bending machine is one of the methods the other types of plate rolling machine can take it for reference.
P the total pressure acting on the roller kN. CALCULATIONS OF COMPONENTS 31 Design of Spur Gear Material EN8 hardened and tempered S ut 550nmm2. The aim of the research is to design a rolling machine that can roll metal sheets of up to 3 mm thickness.
A Project Report On DESIGN AND FABRICATION OF SHEET METAL ROLLING MACHINE Submitted By HARSHDEEP SINGH INAYATULLAH FAROOQUI Under the guidance of Prof. Plate Rolling Machine Calculation The calculation of the main driven power of the plate roll bending machine is the key reference data for. Operating Parameters of the Machine Begin with selecting the correct machine to roll the part on.
The rolling is carried out in a modern and very powerful four-high mill from 1997 shown in Figure 4. Features of Three Roller Rolling Machine. A Plate Rolling Machine is a machine that will roll different kinds of metal sheet into a round or conical shape and a rod bending machine will roll or bend different kinds of metal sheet into right angles or circular shapes.
The slab thickness is normally 220 mm but also 290 and 140 mm exist. Calculation of motor driving power of plate rolling machine. The lower roller of the plate of plate rolling machine is the 2653 1 For thickness F 2 T R neutral layers radius of the rolling in mm R 05 d min R 05388 194 mm F 2 F 2 11563 N According to the force balance the pressure force F 1 which is generated by the upper roller acting on the rolling plate ie 2F 2 F 1.
This paper presents the design construction and evaluation of a sheet metal rolling machine for small-scale enterprises. All the material is reheated before rolling up to 1160-1245C. The three rollers are driving rollers.
