Planing machine head for blade clamping comprises plastics enrobed welded packet of strips punched from steel sheet for reduced weight.

摘要

The main body (11) of the plane head presents an axial packet (20) of punched strips (21) inserted in a threaded support (22) positively inserted in the packet in the form of an axially continuous rectangular bar (23) inserted in holes punched into the strips . The strips are welded to one another and mounted on a shaft which is joined to it in the form of a plastics-enrobed packet. The bar should lie axially free between the end strips (211) which however remain solid where facing the remaining strips and the adjacent strips bordering on the tapped holes (18) in the bar have punched holes (28) to extend from the strip holes to the nearest strip edge. The packet strips are punched from steel sheet.
