SHOT BLASTING MACHINES FOR WIRE AND BARS

  /   Wire and Bar

Single Blast wheel machines ( Inline ) – bars

Components held in rubber belt cavity formed between barrel head plates. The rotation of the barrel head plate causes the components to tumble. The high velocity abrasive from the top clean the components from all sides. Applications – forging / castings and Al die casting.

Double Blast wheel machines – inline for bars

Double blast wheel machines are used in two cases –

  • either for higher production rates with a small increase in floor space area
  • or for specific large sized flats that cannot otherwise be accommodated in the pattern from a single wheel.

Three / four Blast wheel machines ( Inline ) – bars

Three / four blast wheel ( inline ) machines are used for large quantities of square, flat and hex section which cannot be rotated spirally and the quantity does not justify two passes through the machine. The picture indicates the arrangement of the wheels around the section. Higher line speeds are possible as the bar / section is conveyed linearly only

Four Blast wheel / Three Blast wheel configuration

Three Blast wheel machine for square, hex and other sections.

Four Blast wheel machines ( across ) for bars.

These machines are recommended for higher volumes of square, flats, hex and special section. Multiple bars are placed on a roller conveyor and made to pass through the Shot Blasting cabinet and four blast wheels placed across the line of the axis, clean the sections from all the sides ( as shown in the figure.

Roller conveyor type shot blasting machine for square, hex and other sections.

Online shot blasting machine for wires.

Online shot blasting machines are aligned in line with the CDL ( combined drawing lines ) or the bull block type drawing line. The machine is selected on the basis of the rated line speed of the drawing line. These machines are continuous type and works in sync with the drawing line. 7 roll horizontal and 5 roll vertical straighteners are installed at the entry of the machine to straighten the wire as it passes through the blasting zone. The wire is pulled through the machine by the drawing line.

Offline shot blasting machine for wires – batch type.

These are batch type shot blasting machines for wire bar coils. The coils are loaded on mandrels mounted on the doors of the machine and the door is closed. The mandrel rotates clockwise and anti clockwise thereby exposing the coil to the blasting pattern from the blast wheels. The special projections on the mandrel opens the coils and the blasting is penetrated to the inner side of the coil to get a thorough cleaning.

Offline shot blasting machine for wires – crane operated

Instead of door mounted mandrel, we have come up with a innovative and easy handling of the coil using a dedicated crane for the machine. This reduced the dependence on the plant cranes for the loading and unloading of the coil with enhanced safety.
