Study Notes
Forging and Smithy
- Forging is a cost-effective way to produce net-shape or near-net-shape components and can be used for virtually all metals.
Tools and Equipment Used in Smithy and Forging
- Smith's forge or hearth:
- Used for heating purposes during smithy operation
- Made of cast iron or cast steel with a four-legged support, hearth, chimney, and hood
- Has an opening for air supply and a water tank for quenching
- Anvil:
- Important tool for supporting work during hot metal hammering
- Has a hardie hole (square shape) for holding swages, fullers, etc.
- Has a pritchel hole (circular shape) for bending rods and hot punching
- Swage block:
- Made of cast steel with different shaped slots and through holes
- Used for squaring, sizing, heading, bending, punching, and forming operations
- Hammers, tongs, hardie, fullers, and swage punch and drift are other tools used in smithy and forging.
Fitting Work Tools
- Classified into four categories:
- Job holding devices (e.g., vices)
- Striking tools
- Cutting tools
- Measuring, marking, and testing tools
Job Holding Devices
- Vices:
- Most suitable and widely used tools for gripping different jobs
- Types: parallel jaw vice/bench vice, leg vice, pipe vice, and hand vice
- Bench vice is the most commonly used in general fitting work
- Pipe vise:
- Used in plumbing to hold pipes or tubing secure while cutting or threading
- Can hold pipes from 3 mm to 200 mm in diameter
Measuring, Marking, and Testing Tools
- Universal surface gauge:
- Used for layout work and inspection
- Consists of a rigid base, a spindle carrying a scriber in a universal clamp, and a surface plate
- Used for marking and checking the accuracy of a right angle (90 degrees)
Forging and Smithy Shop (Primary Shaping Processes)
- Smithy:
- Defined as handling relatively small jobs only
- Work is carried out using hand hammers or small power hammers
- Forging:
- Production of jobs that require heating in a closed furnace
- Work is normally performed using heavy hammers, forging machines, and presses
- Implies the use of powerful pressure on metal heated to its plastic range
Learn about the tools and equipment used in smithy and forging, including the smith's forge, anvil, swage block, hammers, tongs, hardie, fullers, swage, punch, drift, and hearth. Understand the purpose of each tool in the forging process.
