automatic pneumatic hammer pdf
SYNOPSIS
Moulding is one of the important metals forming process in manufacturing components for various applications in industry. Casting of any size and shape can be made accurately. Automation in this field helps to improve the foundry environment and accuracy of the cast parts. Efficiency of moulding is affected by various parameters like permeability, collapsibility, adhesiveness etc. So it is a must to avoid defects in casting. The defects occur in sand castings post a great problem in foundry and all industries. This automatic hammer is used to for all industries. The hammer is operated in pneumatic power.
Even though skilled labor is employed for hammering operation, the packing of moulding sand will not be even throughout the moulding box. So we have selected the idea of fabricating AUTOMATIC PNEUMATIC HAMMER . This Hammer is operated pneumatically. By using this hammer moulding sand will be packed evenly throughout the box.
INTRODUCTION
The Sensor Operated Automatic hammer is used for hammering the sand, metal, etc uniformly around the pattern. It can be used even in small scale industries. To operate this hammer an air compressor is needed. A butt which is attached to the bottom of the piston rod does the operation of hammering. The pressure developed inside the cylinder reciprocates the piston and hence the butt. This hammer is handled by an operator just by moving it over the moulding sand. The butt rams the sand at places moved and the sand is uniformly rammed. This hammer reduces the hammering time and labor. Due to this the cost is reduced considerably. So this machine finds application in foundries.
INDUSTRIAL APPLICATIONS
The hammer can be handled by an operator without feeling uneasiness. No separate skill is required to operate this hammer. The operation is quick and hence it is a time saving one. The operation is easy and consumes less cost. Due to the above reasons it finds its extensive application in manufacturing industries.
It has an extensive application in both large scale and small scale industries because of its economy and easy handling.
ADVANTAGES
1. Uniform hammering of sand is obtained by this hammer.
2. The time consumption for hammering is reduced greatly.
3. Skilled labor is not required.
4. Easy operation
5. It can be transported easily from one place to another since dismantling and assembling is simple.
6. It reduces more labor for hammering operation.
7. Maintenance is easy.
DISADVANTAGES
1. The initial investment is high when compared to hand hammering.
2. Air leakage affects the efficiency.
