Abstract

Provided is a finishing processing method, including placing an inner panel having a protrusion and an outer panel on each other, and, by using a hemming finishing punch having an arc-shaped pressing surface and having a relief hole of a size corresponding to the protrusion at a central part of the pressing surface, pressing the outer panel so that the arc-shaped pressing surface is rolled along an end portion of the outer panel and the relief hole corresponds to the protrusion.

Claims

1. A hemming finishing punch

having an arc-shaped pressing surface for pressing an outer panel placed on an inner panel, and

having a relief hole of a size corresponding to a protrusion of the inner panel at a central part of the pressing surface.

2. A robot, comprising

the hemming finishing punch according to claim 1.

3. The robot according to claim 2, further comprising

a hemming roller, wherein

the hemming finishing punch is provided to be adjacent to the hemming roller.

4. A finishing processing method, comprising:

placing an inner panel having a protrusion and an outer panel on each other; and

by using a hemming finishing punch having an arc-shaped pressing surface and having a relief hole of a size corresponding to the protrusion at a central part of the pressing surface, pressing the outer panel so that the arc-shaped pressing surface is rolled along an end portion of the outer panel and the relief hole corresponds to the protrusion.

5. The finishing processing method according to claim 4, wherein

the hemming finishing punch is provided on a robot hand of a robot, and the press is performed by operation of the robot.
