APRON MECHANISM IN LATHE

APRON MECHANISM IN LATHE Apron Mechanism: Apron is attached to the carriage and hangs over the front side of the lathe bed. It is useful in providing power and hand feed to both carriage and cross-slide. It is also used to provide power feed to the carriage during thread cutting through two half nuts. The construction of apron is shown in Fig. Fig - Apron Mechanism Construction Power is transmitted from the spindle to the lead screw and feed rod through the spindle gear and tumbler gear arrangement. A worm is mounted on the feed rod by a sliding key. The worm meshes with a worm gear on whose axis another gear G1 is attached. Gear G1 is attached to a small gear G2 by a bracket as shown in the diagram. Gear G4 is positioned to be in mesh with the rack gear always. Another gear G3 is mounted on the same axis of gear G4. The carriage hand wheel meant for longitudinal feed is attached to the gear G5 on the same axis. The gears G3 and G5 are always in mesh. The gear G

Boiler Mountings - Dead Weight Safety Valve

DEAD WEIGHT SAFETY VALVE Function:- A valve is placed upon a valve seat that is fixed upon a long vertical pipe having a flange at the bottom for fixing at the top of the boiler. Suspended at the top of the valve is the weight carrier that carries cast iron rings. The total weight must be sufficient to keep the valve on its seat against the normal working pressure. When the steam pressure exceeds the normal limit, it lifts the valve with its weight & the excess steam escape through the pipe to the outside. This valve is used only with stationary type of boilers. It is the most elementary type of safety valve. The objection to dead weight safety valve is the heavy weight that has to be carried.

SCOPE OF CAD/CAM/CAE

SCOPE OF CAD/CAM/CAE Integrated CAD/CAM/CAE Software like Pro/Engineer, I-DEAS & CATIA help manufacturers optimize product concept early in Design process, enabling them to significantly improve product quality, while reducing product development time and cost. Moreover people having 3D CAD/CAM/CAE knowledge have better chances of growth, immediate employability after completion of course, graduation and chances of jobs abroad. As the market economy opens more and more it has become extremely competitive and with this state of economy, skilled people play the most important role in organization. Hence it becomes imperative on the part of top Tool Room Training centers and Engg. Colleges to especially look for new initiatives towards improving the skills and knowledge of students. An emerging trend of Engg. Education in Tool Room and the world is the rapid incrementation of CAD/CAM/CAE software as an essential part of curriculum. Pic - Scope of CAD/CAM/CAE The prim
