Abstract

Hemming finishing pliers press and thereby bring a folded portion of a panel into close contact with an inner surface side of the panel facing the folded portion, by a clamping action of first and second holding arms. A pressure receiving plate for supporting an outer surface of the panel is provided in a tip end portion of the first holding arm. A pressing claw for pressing the folded portion against the panel supported by the plate is provided in a tip end portion of the second holding arm. A pressure receiving surface of the plate facing the outer surface of the panel is set wider than a pressing surface of the claw facing the folded portion. A supporting wall for supporting a flexed part of the folded portion is formed in the plate. Accordingly, the pliers enable efficient hemming finishing without requiring a skill.

First claim

What is claimed is:

1. Hemming finishing pliers comprising:
First and second plier bodies connected together to be turnable relative to each other in mutually intersecting intermediate portions thereof by use of a pivot shaft, the first and second plier bodies including:
first and second holding arms formed on one-end sides of the first and second plier bodies, and
first and second handles formed on opposite-end sides of the first and second plier bodies and configured to open and close the first and second holding arms,
in which the pliers are configured to press and thereby bring a folded portion of a panel into close contact with an inner surface side of the panel facing the folded portion, by a clamping action of the first and second holding arms, wherein:
a pressure receiving plate for supporting an outer surface of the panel is provided in a tip end portion of the first holding arm,
a pressing claw, for pressing the folded portion against the panel supported by the pressure receiving plate, is provided in a tip end portion of the second holding arm, the pressing claw including a pressing surface having a first width, the pressing surface configured for placement facing the folded portion,
a pressure receiving surface of the pressure receiving plate, configured for placement facing the outer surface of the panel, has a second width that is set wider than the first width of the pressing claw's pressing surface,
a supporting wall, for supporting a tubular bead portion of the folded portion is formed on the pressure receiving plate, the supporting wall extending substantially continuously across substantially the entire width of the pressure receiving plate and being configured to position the pressure receiving surface relative to the tubular bead portion when the folded portion is received on the pressure receiving surface, and relief recess is provided in the second holding arm at a position adjacent to the pressing claw, the relief recess being disposed in a space between the pressing claw and the supporting wall, the relief recess further being configured to receive the tubular bead portion therein when the pressing claw presses the folded portion against the pressure receiving surface,
and further wherein a supporting surface of the supporting wall, configured for placement facing the tubular bead portion, is formed as a curved surface having a radius of curvature along its width having a center of curvature that lies on the central axis of the pressing claw's pressing surface when the pressing surface is in contact with the pressure receiving surface.
