BATTERY OPERATED HACKSAW

INTRODUCTION:

We have pleasure in introducing our new project “AUTOMATIC BATTERY OPERATED HACKSAW”, which is fully equipped by wiper motor. It is a genuine project which is fully equipped and designed for Machines. The HACKSAW system is a fully automation project. This is an era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation. The operation remains an essential part of the system although with changing demands on physical input as the degree of mechanization is increased.

Hacksaw

A hacksaw is a fine-toothed saw, originally and principally made for cutting metal. They can also cut various other materials, such as plastic and wood; for example, plumbers and electricians often cut plastic pipe and plastic conduit with them. There are hand saw versions and powered versions (power hacksaws). Most hacksaws are hand saws with a C-shaped frame that holds a blade under tension. Such hacksaws have a handle, usually a pistol grip, with pins for attaching a narrow disposable blade. The frames may also be adjustable to accommodate blades of different sizes. A screw or other mechanism is used to put the thin blade under tension. Panel hacksaws forgo the frame and instead have a sheet metal body; they can cut into a sheet metal panel further than a frame would allow. These saws are no longer commonly available, but hacksaw blade holders enable standard hacksaw blades to be used similarly to a keyhole saw or pad saw. Power tools including nibblers, jigsaws, and angle grinders fitted with metal-cutting blades and discs are now used for longer cuts in sheet metals. On hacksaws, as with most frame saws, the blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. In normal use, cutting vertically downwards with work held in a bench vice, hacksaw blades should be set to be facing forwards. Some frame saws, including Fret Saws and Piercing Saws, have their blades set to be facing the handle because they are used to cut by being pulled down against a horizontal surface.

Blades

Blades are available in standardized lengths, 10 or 12 inches (254 or 305 mm) for a standard hand hacksaw. “Junior” hacksaws are 6 inches (152 mm) long. Powered hacksaws may use large blades in a range of sizes, or small machines may use the same hand blades.

TYPES OF BLADES:

1.High Carbon Steel

2.Low Alloy Steel

3.Bi-Metallic Steel

4.High Speed Steel

Component List:

  • HACKSAW

  • MODEL FRAME

  • SHAFTS

  • DC BATTERY

  • DC MOTOR

ADVANTEGES:

  • Weight of machine less

  • It reduce the work of labor

  • Easy to make because of simple construction

  • High production rate.

  • Cost is less

APPLICATIONS:

  • In Engineering industry

  • In Construction industry

  • In workshop

CONCLUSION:

We have learnt how the theoretical design is possible is possible in practical. Other Hacksaw machine is only cut one part at one time but this machine cut the four part at a time, this hacksaw machine has lighter weight as compared to other machine. The cost of machine is less and easy to operate so it affordable for all industry.

Future Scope:

We can try to change the speed of motor cutting the different metal at various speed if it possible. So we can make the changes as well in the project as per the requirements.
