  • Extrusion punch and method of construction
    Patent number: 4368634
    Abstract: An extrusion punch, especially for use in a back extrusion process, wherein a hard wear resistant material is joined on one end to a steel punch body. The hard wear resistant material is joined on at the tip of a steel body so as to prevent wear due to abrasion on the punch caused by the material being extruded in a die means. The hard wear resistant end cap on the tip of the steel body is joined so that it may easily and quickly be replaced when the punch is in position on the machine thereby providing less down time for maintenance on the extrusion press. The method of joining the hard wear resistant end cap to the steel body minimizes the conditions which tend to fracture hard wear resistant material.

  • Punch and method of construction
    Patent number: 4125007
    Abstract: A punch for working material, such as an extrusion punch, wherein a hard wear resistant material is joined on one end to a rigid body, preferably a steel punch. The hard wear resistant material is joined on at the tip of the rigid body so as to prevent wear due to abrasion on the punch caused by the material being worked. The hard wear resistant end cap on the tip of the steel body is joined so that it may easily and quickly be replaced when the punch is in position on the machine thereby providing less down time for maintenance on the extrusion press. The method of joining the hard wear resistant end cap to the steel body minimizes the conditions which tend to fracture hard wear resistant material.
