MANUFACTURING SHOP:

MANUFACTURING SHOP 1) PATTERN SHOP A pattern may be defined as a replica model of the desired casting which, when packed or embedded in a suitable moulding material, produces a cavity called MOULD. This cavity, when filled with a molten metal, produces the desired casting after solidification of the poured metal Material For Pattern Wood 2. Metal 3. Plaster 4. Plastics 5. Wax

PowerPoint Presentation:

Types of Pattern : Solid or Single piece pattern Two piece or split pattern 3. Multi-piece pattern 4. Match plate pattern Gated pattern Skeleton pattern Sweep pattern Pattern with loose pieces Cope & Drag pattern Follow Board pattern 11. Segmental pattern. Pattern Allowances:- Shrinkage Allowance Machining Allowance Draft Allowance Rapping or shake Allowance Distortion Allowance Mould-wall movement allowance.

PowerPoint Presentation:

2) FOUNDARY SHOP A foundry is a place in an industry, where the moulds are prepared with the help of different types of things(such as sand, bentonite, fire clay, dextrine etc.) and poured them with molten metal to get the solid casting which can be used for specific purposes after machining with in specified limits and dimensions. Terminology of Foundry Sands:- Green Sand Floor black or baking sand Dry Sand Baking sand Facing Sand Parting Sand Core Sand Oil Sand Molasses sand Air setting (No Bake) Sand

PowerPoint Presentation:

Charge Composition and Chemistry (Tractor Casting) Charge: Pig Iron 10-15% Steel scrap 25-30% H. Scrap Balance Final Analysis: % carbon 3.20-3.35% % silicon 2.0-2.2% %manganese 0.6-0.8% % CE valve 3.9-4% Inoculation: Ladle (Fe Si granules) 2-4kg/800kg of metal Tapping temp. 1480 ◦ C Pouring temp. 1370 ◦ C

PowerPoint Presentation:

3) CUTTING SECTION The cutting section provides the raw material to the various sections to manufacture the different type of components. The long bars are cut in the cutting section with the machining allowance so that the desired component can get after machining and facing and centering also done in the cutting section then the raw material is dispatched to the next section for further operations. Grinding Machine Circular saw 1000 mm cutter diameter Circular saw 600 mm cutter diameter Power Hack saw – 2 no. SPM side milling machine – 3 no. Drilling machines – 3 no. Column drilling

PowerPoint Presentation:

4) MACHINE SHOPS The process to cut or remove the unwanted material from the surface of the component to get the desired shape and size, with the help of machine tools. Light Machine Shop Heavy Machine Shop Machine Tool Division Small Parts Section

PowerPoint Presentation:

5) HEAT TREATMENT SECTION The process of Heat Treatment involves heating of solid metals to specified temperatures holding them at that temperature and then cooling them at suitable rates in order to enable the metal to acquire the desired properties to the required extents. To change the properties of the metal or to get the required properties with the help of heat as per design. 1. To relieve internal stresses. 2. To improve mechanical properties. 3. To improve machinability . 4. To change the internal structure.

PowerPoint Presentation:

VARIOUS HEAT TREATMENT PROCESSES : 1.ANNEALING 2. NORMALIZING 3. HARDENING 4. TEMPERING 5. CASE HARDENING 6. SURFACE HARDENING

PowerPoint Presentation:

6) PRE-TREATMENT AND PAINTING SHOP Pre-treatment and painting shop is the section to treatment and painting for the sheet metal parts of the tractor such as; mud-guards, fuel tanks, bonnets etc. It is required so that the appearance of the tractor can be save for a long period.
