Welding point cutter for separating spot-welded sheet metal comprises a shaft connected at one end to a cutting part via a form-locking connection having joint surfaces lying at right angles to each other

摘要

Welding point cutter comprises a shaft (3) which is connected at one end via a form-locking connection to a cutting part (16) and is axially displaced relative to a center part arranged in an axial holder of the shaft and the cutting part. The form-locking connection has joint surfaces (20, 22, 28) lying at right angles to each other. Preferred Features: The shaft-side form-locking connection and the form-locking connection of the cutting part are L-shaped grooves. One part of the joint surfaces of the shaft and cutting part runs perpendicular to the axis of the weld point cutter for insertion of the cutting part and extends up to the outer casing of the shaft or cutting part. Another part of the joint surfaces of the shaft and cutting part extends in an axial direction. The center part (14) lies under the force of at least one pressure spring (11).
