A method of manufacturing a rotating bearing unit includes to cause one end surface in the axial direction of the forming punch (46), formed by combining a plurality of punch elements (46, 46) divided in the circumferential direction, which are displaceable in the axial direction and which are not displaceable in the circumferential direction, and having a processing teeth (44, 44) at one end surface in the axial direction, to face the other end surface of the caulking section (20) in the axial direction. In this state, rolls (30a) are rotated about the central axis (α) of the hub main body (8) while pressing the other end surface of the forming punch (46) in the axial direction with a pressing surface (43) of the roll (30a) having a central axis (β) that is inclined with respect to the central axis (α) of the hub main body (8).

Provided is a roller hemming apparatus capable of preventing positional misalignment of a lower plate workpiece during a bending process. A roller hemming apparatus of the present disclosure includes a die configured to hold a first workpiece which is a plate material, and a roller configured to bend an edge of the first workpiece onto an edge of a second workpiece, which is a plate material placed on the first workpiece held in the die, to overlap each other, the die including a suction mechanism that opens toward a workpiece contact surface against which a hem flange on a peripheral edge of the first workpiece abuts, and that suctions the first workpiece. Thus, positional misalignment of the first workpiece is prevented during a hemming process.

A vertical Pittsburgh Seam closing apparatus having a base supporting surface, a track mechanism for moving a carriage assembly which holds seam forming members used to close a Pittsburgh Seam, a pair of upper and lower guide members for guiding the duct section into a proper vertical position, and upper and lower clamping members positioned inside the duct section and adjacent the inside portion of the Pittsburgh Seam to be closed, the upper guide members and clamping member being selectively movable and adjustable for accommodating different duct section lengths. In one embodiment, the seam forming assembly includes three roller members mounted in vertical arrangement to each other, one roller member being V-shaped in configuration and the other two roller members being substantially cylindrical in shape. The V-shaped roller member may also include one or more projecting members for forming dimples in the closing process to prevent shifting and/or slipping of the closed seam.

A modular roller hemming system having a base assembly, a replaceable anvil, a spider arm assembly, a plurality of support arms for supporting the spider arm assembly, and a plurality of repositionable unit tools. The anvil is 3-D printed of a polymer composite material and may be replaced with similarly manufactured anvils having different form factors for receiving various shaped and dimensioned workpiece assemblies. The plurality of support arms are repositionable on the base assembly, the spider arm assembly is reconfigurable, and the plurality of unit tools are moveable to accommodate various anvils having different form factors. The support arms includes an upper segment that is detachable from the lower segment to facilitate the changeover of anvils.

In one embodiment, the method includes providing a double sheet metal element including the two sheet metal end sections; and creating a connecting section along the connecting line. The creation of the connecting section includes introducing a first depression into the double sheet metal element, and creating a first folded section of the double sheet metal element. The method further includes orienting the connecting section relative to an extension plane of the double sheet metal element so that the connecting section extends perpendicularly to the extension plane.

A vehicle panel roller hemming device includes roller hem equipment including: a positioning mechanism configured to position an outer panel on a hemming die by a locator; and a suction and fixing mechanism configured to suck and fix a lower face of the outer panel by a vacuum pad. The suction and fixing mechanism includes a pad base part; a skirt part continuously rising with a predetermined thickness from an edge of the pad base part and including an opening on an end edge thereof; a decompression space formed by an inner wall of the pad base part and an inner wall of the skirt part; and a suction through pipe penetrating the pad base part and communicating with the decompression space, and configured to suck air inside the decompression space.

An apparatus for seaming roof assemblies having a modular provision of tooling stations is disclosed herein. Such an apparatus includes multiple tooling stations that may be added or removed on demand in order to facilitate different degrees of seaming engagements as needed. Such a device utilizes horizontal rollers to provide seaming of overlapping roof panel ends to reduce the potential for separation thereof after building erection has been undertaken, further impeding water egress therethrough and wind updraft damage, at least, as well. The modular device thus provides a manner of selecting specific numbers of horizontal rollers for seaming contact with metal roof panels, thereby allowing for different types of panels and end structures thereof, as well as reduce the propensity for jamming of such multiple rollers during utilization. The method of utilization of such a modular device is encompassed herein as well.

A vertical Pittsburgh Seam closing apparatus having a base supporting surface, a track mechanism for moving a carriage assembly which holds seam forming members used to close a Pittsburgh Seam, a pair of upper and lower guide members for guiding the duct section into a proper vertical position, and upper and lower clamping members positioned inside the duct section and adjacent the inside portion of the Pittsburgh Seam to be closed, the upper guide members and clamping member being selectively movable and adjustable for accommodating different duct section lengths. In one embodiment, the seam forming assembly includes three roller members mounted in vertical arrangement to each other, one roller member being V-shaped in configuration and the other two roller members being substantially cylindrical in shape. The V-shaped roller member may also include one or more projecting members for forming dimples in the closing process to prevent shifting and/or slipping of the closed seam.

A roller hemming apparatus includes a receiving body including a receiving member coming into contact with an edge of a panel workpiece, a roller body including a roller member bending a panel flange at the edge of the workpiece toward the receiving member, and a movement unit moving the roller body along the edge and tilts up or down the roller body toward the flange. The roller member hems the flange through the tilting-up operation of the roller body. One of the receiving and roller bodies includes a guide recess and the other includes a convex curved surface coming into sliding contact with the recess. The recess and the surface have a same curvature. The roller body is tilted up to bend the flange or tilted down to move away from the flange around a center of curvature common to the surface and the recess that come into sliding contact.

A cleaning device for a hemming roller cleans the hemming roller of a hemming roller unit mounted on an arm tip of a hemming robot. The cleaning device includes: a support frame installed on a floor of a workshop; a roller rotation unit that is installed on an upper surface of the support frame and rotates the hemming roller that has entered the upper surface of the support frame through the hemming robot; and a scraper that is installed to be movable back and forth on the support frame while facing the roller rotation unit and removing foreign substances on the surface of the hemming roller.
