TURN SHEAR

Machinery Systems

Until now, shape of the sheet was only a rectangle, In view of process rationalization and better yield of the sheet,molt angular shape sheet has been requested by the Customers,
Hitachi Engineering & Services Co.,Ltd. has been developing to cut various shape by means of single shear calling upon such Customer's request, and excellent performance is obtained.

Economical advantage of the turn shear

Productivity
  1. Further process is eliminated.
  2. Continuous cutting of various shape is carried out.
  3. Change in shape can be done within a limited time.
Quality improvement
  1. Accuracy in cutting.
    general: }3.0 mm
    high precision: }0.5 mm
  2. Error in angle.
    general: }5 min.
    high precision: }30 sec.
Easy maintenance
  1. Structure is very compact and easy operation.
  2. Easy clearance set up of knife.
  3. Easy set up change in sheet length and angle.
Yield improvement
  1. Minimum amount of scrap at both ends and edge.
Easy replacement
  1. Easy replacement of this turn shear to existing process line.

Characteristic of turn shear


Insert type to the press

  1. Every operation is curried out with N.C. circuit.
  2. Improvement of accuracy in cutting by centering and angle trace control mechanism.
  3. Adoption of select switch to set up sheet shape.
