           CHAPTER 2 : OVERVIEW OF DIFFERENT
                                 DEPARTMENT
Acey consist of four department they are Spring Department, Outer Department,Stranding
Department and Assembly Department. Below fig gives an idea regarding organised
layout of the departments until final product is manufacture.
           Spri
Inner Wire
In Spring Department, Spring is manufactured from raw materials like Stainless Steel and
Galvanized Steel. Spring is a helical winding or a sheaf of steel. Spring manufactured in
this department prevent inner wire from damaging due to external forces or banding and
also allow frictionless ease movement of inner wire.

Table2.1Differentthicknessofflattenwire
In this process spring or sheaf of steel is produced by winding flatten wire on liner. Spring
prevent inner wire from damaging and also allow inner wire to move with ease. The
machine use to manufacture is auto winding machine. Auto winding machine is a modified
lathe machine in which chuck consist of set of three guiding rollers and carbide die tool at
the centre. Initially spool of flatten wire is loaded at tail stock of auto winding machine.
And liner on which flatten wire is to be winded is fed through the head stock. Then flatten
wire is manually fed through the guiding roller and then through the carbide forming die.
Then the chuck is rotated for two to three turns of spring. The spring starts for mingon
liner & coming out of die. Now Start the Machine by pressing the Switch. The Machine
start coiling of spring which shall come out on the Right hand side of machine through the
tail stock continuously. Auto winding Machine is shown in figure Fig 2.3.
Maintenances Process
    -     Send tools for maintenance as per the tool maintenance schedule or when non-
          conference takes place asper the filing for mat of the tooling work order. As you get
          the tools, update the tool history card.
    -     Dusting or cleaning zinc powder or torso.
    -     Clean the head stock with an air jet or duster.
    -     Check the free rotation of the coiling pin and replace it if it deserves to be replaced.

In this process continuous helical spring is coiled on Spring coiling machine. In this type
of machine there are four tools used to make a spring. This spring are more flexible in
comparison to the auto-winding spring. Long pipes are used to contain this spring as they
have high flexibility and cannot be kept in a basket. Helical spring can be made from this
type of machine. Spring coiling machine is shown in the Fig 2.4 below.
Operation Process
  -   Turn on the switch of the machine, make the spring approximately 100 to 150 mm
      according to the manual control.
  -   Turn off the machine, pull the mandrill and pull the extra flat wire out of the start
      end of the sting.
  -   Pass the mandrel through the collet with the spring, open the collet lock and rotate
      the collet spring as required to hold the collet spring tight.
  -   The pressure is maintained. Turn on the machine and make an approximate one-
      meter spring. Check the outside diameter with a micro metre and scale Spring
      stiffness on the machine with a scale Check.
  -   Visually check the overlap and gap of the spring. Set the tension of the guiding
      bucket and pay off the bobbin if the gap appears. Check the fee rotation of the
      sliding roller if it overlaps.
  -   If there is a whirlpool or bend in the spring, Reduce the holding pressure to reduce
      the whirlpool but be careful not to sleep from spring collect. If the flat coil looks
      OK, Pass the spring through the spring guide tube. In the machine when the spring
      touches the end of the spring guide tube shut it down.
Maintenances Process
 -    If the I.D. If it seems low, check the Mendel diameter and change it if
      necessary or adjust the bearing pressure to increase the ID.

Core winding process is done to increase strength and load caring capacity of core wire.
Machine used in this process is Core winding Machine shown in Fig 2.6. This machine is
used to combine Stainless steel or Galvanized steel wire into one core wire or central wire.
The core wire is a combination of 7 wire of raw material wires. Core winding process
increases strength of the load carring capacity of core wire. The machine use for core
winding process is known as Bunching machine which shows in below figure.
Rewinding Process
Core wire bobbin from the core winding machine is rewinded into small size bobbins.
Rewinding is done to increase flexibility of core wire and also
help unbending the bend occurs during core winding process. Rewinding of core wire into
small size bobbins is also important so that it can be loaded in stranding machine.
Wire Standing Machine
We saw wire stranding machine in which inner wire is made by 1*6 structure and this
inner is used as core wire in 1 * 6 * 12 and also used as core wire in 7*7. Then we saw
wire stranding machine in which inner wire with 1*6 * 12 structure is prepared. 12
different bobbins are set in the bobbin tube and 1 *6* 12 inner wire can be made using
it. Similarly in bobbin tube 6 different bobbins are set up to create an inner with 7 * 7
structure. Inside 6 bobbins are 1 *6 core wire. This is how a 7* 7wire rope is made from
it.WirestrandingmachineandstrandingprocessisshowninFig2.13&Fig2.14.Table
