ABSTRACT:
An auto body decrimping tool assembly for decrimping a panel from a vehicle frame. The decrimping tool assembly includes a hollow housing body member with a first aperture at one end and a second aperture. A decrimping head member is pivotally mounted near an end thereof on a drive shaft member rotatably secured in the body member's second aperture. The decrimping head member includes a base portion having a protruding contact section and an opposed, protruding blade section having a concave, helical surface facing the contact section. The blade section includes a tapered edge at a side of the concave, helical surface opposite the base portion. The decrimping head member is mounted to the drive shaft member at the contact section.The decrimping head member is positioned at an edge of a panel crimped to the frame with the contact section on an edge of the crimped panel and the tapered edge of the blade section between the crimped panel and the frame. A power source, positioned at the body member's first aperture and operably connected to the drive shaft member, imparts reciprocal rotary motion to the drive shaft. The drive shaft causes the blade section and tapered edge of the decrimping head member to reciprocally pivot relative to the contact section, thereby incrementally decrimping the panel from the frame as the crimped panel and frame move between the blade section and the contact section of the decrimping head member.
