ME-311, Machine Design Practical B.Tech Part III, Vth Semester, Mechanical Engineering, 2016-2017 Riveted ts Note: (a) Indicate all the dimensions in of proportions as shown in figure. (b) Take diameter, d = 12 mm , if it is not mentioned in the problem. 1. Draw the following types of rivet heads as shown in Fig.1 and take the diameter of rivet, d = 20 mm. Indicate the proportions in of diameter of the rivet. 2. Draw the top and sectional front view of a single riveted lap t as shown in Fig. 2. Take thickness of the plate t = 10 mm and pitch, p = 3 d, and margin, m = 1.5 d. 3. Draw the top and sectional front view of a double riveted lap t as shown in Fig. 3. (i) Chain and (ii) Zigzag riveting. Take thickness of the plate t = 10 mm and pitch, p = 3 d, transverse pitch, pt = 0.8 p for chain riveting, and transverse pitch, pt = 0.6 p for Zig-Zag riveting and margin, m = 1.5 d. 4. Draw the top and sectional front view of a single riveted butt t as shown in Fig. 4. (i) Single cover plate and (ii) double cover plate. Take thickness of the plate t = 12 mm, t1 = 1.125 t for single cover plate, & t2 = 0.8 t for double cover plate, pitch, p = 3 d, and margin, m = 1.5 d. 5. Draw the top and sectional front view of a double riveted butt t with double cover plates having equal length as shown in Fig. 5 (i) chain riveting and (ii) Zig-zag riveting. Take thickness of the plate t = 12 mm, t2 = 0.8 t, pitch, p = 3 d, and transverse pitch, pt = 0.8 p for chain riveting, and transverse pitch, pt = 0.6 p for Zig-Zag riveting and margin, m = 1.5 d.
6. Draw the top and sectional front view of a triple row and quadruple row butt t with double cover plates having unequal length as shown in Fig. 6. Take thickness of the plate t = 12 mm, t2 = 0.8 t, margin, m = 1.5 d. Take suitable longitudinal and transverse pitch dimensions. 7. Draw the top and sectional front view of the diamond t with double cover plates and having equal length as shown in Fig. 7. Take thickness of the main plate t = 12 mm, and thickness of cover plates as t2 = 0.8 t, and margin, m = 1.5 d. Take suitable longitudinal, transverse pitch and width of the plate.
