AUTOMATIC MACHINES FOR MAKING SPRING WASHERS

 

AUTOMATIC MACHINES FOR MAKING SPRING WASHERS are designed for the manufacture of single-fillet spring washers with internal diameter of 3 to 8 mm out of wire of square and trapezoidal section.

AUTOMATIC MACHINES FOR MAKING SPRING WASHERS are easily maintained, constructed for longterm operation.

 
DESCRIPTION:

The process of making washers consists in:

  • straightening  the   wire  fed  by  means  of a driveless  straightening device installed on the axle of the wire feeder;
  • coiling of wire into  spiral of a  definite  diameter by  means of pushing it with tongs through coiling device;
  • cutting  the washer off the spiral with travelling blade  moving vertically during radial cutting;
  • dropping the finished washer into container.
 
ADVANTAGES:
  • high accuracy of the internal diameter of the washer and  length of reamer which is ensured by easily rearrangeable replaceable units of the machine;
  • possibility of extended dimensions range of  washers  at  one and the same machine;
  • safety during  operation  of  he  machine is  ensured  by  reliable screens  and  housings  with  which moving parts are covered.
 
MATERIALS USED:

for the washers of square section - steel wire with an ultimate strength of 1100 MPa;
for the washers of trapezoidal section - steel wire with an ultimate strength of 700 MPa.
