Making a Funnel using metallic sheet

Aim:-

To make a funnel from a given (GI)metallic sheet.

Tools Required:-

MALLET, SNIP, STAKE, STEEL RULE, BALL PEEN HAMMER, STRAIGHT EDGE, RIVETS, SCRIBER

Procedure:

The size of the given sheet metal is checked for its dimensions using a steel rule
The required development of surface is being made on the white paper which is overlapped on the sheet metal.
The marking is done on the sheet metal as per the development being done on the paper.
Now using straight snips, unwanted materials are removed.
Now fold and bend the workpiece to make the funnel shape and joint is made on the workpieces.
Then using a groover, a locked grooved joint is made for about 5mm. Also, hemming is done in the bottom of the funnel.
In between top face and bottom face, a butt joint is made using a solder.
Finally, trimming and finishing operations are carried out.

Safety Precautions:-

Each cut you make exposes sharp edges and creates burrs that can slice a finger. Must Use Hand gloves when cutting the sheet.
Metal waste also has hazardous edges. So Wear shoes.
Handle metal sheets with care, especially if they are wet.

Result:-

Thus, the funnel of the required dimensions is made from the given sheet metal.

TIN SMITHY & Sheet metal

TIN SMITHY Introduction : Many engineering and house articles such as boxes, cans, funnels, ducts etc. are made from a flat sheet of metal. The process being known as tin smithy. For this the development of the article is first drawn on the sheet metal, then cut and folded, to form the required shape of the article. Allowance should be given in the drawing stage for folding and bending. This allowance depends upon the radius of the bend and thickness of the sheet metal. Sheet Metal Materials : A variety of metals are used in a sheet metal shop such as galvanized Iron, black, Iron, tin, Stainless Steel, copper and Aluminium. Hand Tools : The common hand tools used in sheet metal work are steel, try square, Wire gauge, Scriber, Ball peen hammer, Nylon Mallet, Snips Divider, Stakes, Cutting plier and Soldering Iron. Here, the details of tools that are being equipped by our workshop purpose only are presented. Wire Gauge: The thickness of sheet is referred in numbers known

Fluid mechanics VIVA QUESTIONS and ANSWERS

1. Define density? Ans: It is defined as the ratio of mass per unit volume of the fluid. 2. Define viscosity? Ans: It is defined as the property of fluid which offers resistance to the movement of fluid over another adjacent layer of the fluid. 3. Differentiate between real fluids and ideal fluids? Ans: A fluid, which is in-compressible and is having no viscosity, is known as ideal fluid while the fluid, which possesses viscosity, is known as real fluid. 4. What is a venturimeter? Ans: It is a device which is used for measuring the rate of flow of fluid flowing through pipe. 5. What is a notch? Ans: A notch is a device used for measuring the rate of flow of a fluid through a small channel or a tank. 6. Define buoyancy? Ans: When a body is immersed in a fluid, an upward force is exerted by the fluid on the body. This upward force is equal to the weight of the fluid displaced by the body. 7. Define meta-centre? Ans: It is defined as the point about which a body

Lathe machine introduction

STUDY OF LATHE Aim To study about the lathe . Introduction Lathe is called the father of machine tools. The main function of lathe is to remove metals from work piece to give a required shape and size. In the lathe the work piece is held in a chuck. The tool is moved at an angle 90_ to the axis. Various operations such as straight turning, taper turning, and chamfering, facing, knurling, grooving, thread cutting, taper turning are carried out. When the operations above set are done automatically, then the lathe is called automatic lathe. Working principle of lathe In a lathe, the workpiece is held in chuck and rotates about its axis by means of power. A single point cutting tool is mounted in tool post. When the chuck rotated the work piece also rotated. The tool moves parallel to the axis of rotation of work piece to produce a cylindrical surface, where as the tool moves perpendicular to the work piece to pro
