MOLD SHOP


                                                   Mold

                


The machines that were observed in the mold shop are:

1)     Center lathe machine
2)     Vertical milling machine
3)     Universal milling machine
4)     Copying milling machine
5)     Pantograph milling machine
6)     Surface grinding machine 
7)     Single lip cutter grinding machine
8)     Hobing  press machine
9)     Power  press machine
10)Lapping and polishing machine
11)Shaper machine
                                                  



1)Center lathe machine:
   Main parts :
(1)  Bed
(2)  Headstock
(3)  Tailstock
(4)  Carriage
(5)  Lead screw                                                                    

Operation :  Turning, Taper turning, Facing, Boring, Threading, Drilling, Knurling etc. operation can be done by this machine.


2)Vertical milling machine :
   Main parts :
(1)  Column
(2)  Knee
(3)  Table
(4)  Spindle
(5)  Over arm

Operation : The vertical milling machine is used for face milling profiling, die sinking and for various odd shaped jobs.
In vertical milling machine the spindle has the vertical movement and the table has vertical, longitudinal and transverse movement.


3)Universal milling machine : The universal milling machine is a developed features of the other types of milling machines. It is designed to handle all types of milling machine work. The table has some movements, but it addition it can be swiveled on the saddle. So that it moves at an angle to the spindle in the horizontal plane.

Operation : The universal milling machine is used to cut helical gears, twist drills, milling cutters and various kinds of straight and tapered work.

4)Copying milling machine : There are two types of copying milling machine n mold shop of BITAC. One having capacity 1:1 and the another having capacity 1:1.5 – 1:10, For enlarging a job the position of styles and spindle should be interchange. Its speed is 50-10000 rpm.

Main parts :
1.      Master table
2.      Working table
3.      Working vise

Cutter use in this machine : Single lip cutter
1.      Anvil cutter
2.      Ball nose cutter
3.      Pointer cutter

5)Pantograph milling machine : The capacity of the pantograph milling machine is 1:1 and 1:1.5-1:10. It is used to make ambushing sill, mail sill and latter.

Main parts :
1.      Master table
2.      Working table
3.      Working vise
4.      Cutter spindle
5.      Ratio bar
6.      Stallus

6)Hobing  press machine : Hobing  press machine is one of the important machine of the mold shop. Hydraulic pressure is used to press the job. It can creates 3000 KN pressure. It can produce various types of Padak.

7)Power press machine :

Main parts :
1.      Working table
2.      Block
3.      Dial indicator
4.      Motor

Operation : It is used to create pressure on job to change its deform shape or to do other works.

8)Polishing machine : It is used mainly polishing after different type of machine operation.

9)Shaper machine :
Main parts :
1.      Base
2.      Table
3.      Ram
4.      Frame

Operation : Shaper machine is mainly used for shaping a job.

“Equalizer connection is needed in lap winding armature but not in wave winding “ why ?

The equivalent circuit of a four point – pole dynamo with a simplex winding. The voltage induced in each path is assumed to both to be same and should be if the reluctance of each magnetic path is the same, so that the lines of flux cut by each inductor of each path are the same. However wear of the bearings or deflection of the armature shaft may cause the armature to be closer to some poles and farther from others, thus changing the length of the air gap, and therefore the reluctance of the magnetic circuits of the poles is not identical. This factors cause the voltage in the materials making up the magnetic circuit. These factors cause the voltage in each parallel path differ, and the unequal voltages in turn cause flow of a circulatingcurrent through the windings and brushes , undue heating of the armature and waste the power. To reduce the circulating current, points on the winding which should be at the same potentials are brought to the same potentials by connecting them with …

Boiler


Boiler: A steam boiler is usually a closed vessel made of steel. Its function is to transfer the heat produced by the combustion of fuel to water and ultimately to generate steam.
Types of boiler:
           1. Fire tube or smoke tube boiler            2. Water tube boiler




                                          Figure: Boiler
Fire tube boiler: In fire tube steam boilers, the flames and hot gases, produced by the combustion of fuel pass through the tubes which are surrounded by water. Fire tube boilers are generally used for relatively small steam capacities and low to medium steam pressure. As a guideline fire tube boilers are completive for steam rates up to 12000kg/h and pressures up to 18 kg/cm².Fire tube boilers are available for operation with oil, gas or solid fuel.

Example: Cochran boiler, Locomotive boiler, Scotch marine boiler, Velcon boiler, simple vertical boiler.


Differentiate among progressive die, compound die and combination die.

Progressive die: The dies which performed two or more operations at different stages every time the ram descends is known as Progressive die.
The principle advantage of Progressive die is in the number of operations that can be achieved with one handling of the stock strip. The main disadvantage is that work pieces may become “dished” as they pushed through the die as they generally have very little support.






Compound die: A compound die differs from a progressive die in that it performs two or more cutting operations during one stroke of the press at one station only.

Compound dies are slower in operation than progressive dies but they have advantages for certain jobs, especially where tolerance are close (1)the cutting operation, by the action of the knockout plate ,ensures flatness of the blank.2 Large parts can be blanked in a smaller press if compound dies rather than progressive dies areused.
Combination dies:A die in which a cutting operation is combined with a noncutting operation …
