SHEET METAL DUST PAN
# TOOLS USED:
|Snips||Snips, also known as shears, are hand tools used to cut sheet metal and other tough webs. There are two broad categories: tinner’s snips, which are similar to common scissors, and compound-action snips, which use a compound leverage handle system to increase the mechanical advantage.|
|Rivet||A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite the head is called the buck-tail. On installation the rivet is placed in a punched or drilled hole, and the tail is upset, or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. To distinguish between the two ends of the rivet, the original head is called the factory head and the deformed end is called the shop head or buck-tail.|
|Center Punch||A small steel tool with a conical tip used to punch a small indentation at the location of the centre of a hole to be drilled.|
|Combination Square||A combination square is a tool used for multiple purposes in woodworking, stonemasonry and metalworking. It is composed of a ruled blade and one or more interchangeable heads that may be affixed to it.|
|Protable drill||A portable drill is a tool fitted with a cutting tool attachment or driving tool attachment, usually a drill bit or driver bit, used for boring holes in various materials or fastening various materials together with the use of fasteners. The attachment is gripped by a chuck at one end of the drill and rotated while pressed against the target material. The tip, and sometimes edges, of the cutting tool does the work of cutting into the target material.|
|Counter Sink||A countersink is a conical hole cut into a manufactured object, or the cutter used to cut such a hole. A common use is to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material .|
|Hemming||Hemming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. Hemming is the process in which the edge is rolled flush to itself, while a seam joins the edges of two materials.|
# Machining and bench work process applied:
The metal sheet that is used for making a sheet metal dust pan is measured in size with the help of scale, provided data from the instructor.Then the sheet metal is cut where the line is marked with the help of shear by keeping it on the table. The vice is used to clamp the sheet and the marked region are bent as directed by the instructor. A drill machine is used to make hole in the dust pan to attached the handle using rivet. In this way we can make a sheet metal dust pan.
# Photo of sheet metal dust pan:
- Prepare the development of the dust pan as per dimension directed by the instructor.
- A rectangular metal sheet was cut by the help of shear.
- Remove the unwanted material by using a straight snips.
- Fold the edges on the required size by using a suitable vice.
- Then, the handle of dust pan was made according to the data & handle was proper hemming.
- Using drill machine proper holes was made on the pan & handle.
- Attached the handle and pan using rivet to make the dust pan.
# Technical complications faced during WS-practice:
- While cutting metal sheet, sheet are not cut properly by shears.
- It is hard to operate properly bending of sheet metals.
- Durilg drilling we have to focus to the drill points.
- Difficult to properly rivet.
We should wear aprons while working at the workshop. Drilling should be done only after center punching on the work piece. Work piece should be carefully clamped while drilling. All the tools should be handled properly with lots of care. The edges of dustpan should be burr in order to get rid of injuries.We can know how the dust pan is made.We also know about the tools used in it. We can make anything which is used in our daily life.
