    摘要: A flexible shelving unit includes a support frame having at least one vertical guide rack, the guide rack including an elongated slot. The shelf unit is supported by the guide rack. The shelf unit includes a shelf plate framed by a front reinforcement portion and by at least one side reinforcement portion. The shelf unit when in a release position is moved to selected upward and downward locations by vertical displacement of at least one locating pin connected to and extending from the at least one side reinforcement portion which is positioned and sliding within the elongated slot. A flat end face of the at least one side reinforcement portion directly contacts a plate face of the at least one vertical guide rack with the at least one side reinforcement portion and the shelf plate in a horizontal position to frictionally retain the shelf unit in the horizontal position.

    摘要: A method of joining includes disposing a second workpiece adjacent to a first workpiece. The method further includes identifying a determined hardness parameter of at least one of the first and second workpieces at a welding position. The determined hardness parameter is determined by at least one of estimation, calculation, and measurement. The method includes selecting a weld schedule based on the determined hardness parameter and welding the first and second workpieces together using the selected weld schedule. A welding horn includes a shank and a tip having an end face, the tip being disposed at an end of the shank and configured to contact a workpiece and to transmit energy to the workpiece. Knurls are disposed on the end face, each knurl having a distal end. A curved indenter extends from the end face beyond the distal ends of the knurls.

    摘要: A two-part mechanical fastener comprising an elongated body with a bore slidably carrying a mandrel adapted to interferingly engage the body is described. The fastener body has one or more protuberances on its exterior surface. In an aspect, the protuberances form a thread. The fastener is adapted to form an opening in, and penetrate, a stack of two or more workpieces. To secure the workpieces in the workpiece stack and form a robust joint, the fastener body is deformed by the mandrel, expanding the body, so that a body end engages a surface of the workpiece stack and the one or more protuberances are brought into engagement with the walls of the opening. Methods of using such a fastener to secure non-ferrous or polymer-based sheet-like workpieces to one another are disclosed.

    摘要: A method of joining top and bottom layers of material according to the principles of the present disclosure includes providing a rivet having a head and a headless end, wherein a rimmed edge extends downward from the head toward the headless end, applying a layer of adhesive between the top and bottom layers and allowing the adhesive layer to at least partially cure. The method further includes piercing the top layer with a headless end of a rivet after the adhesive layer is cured, deforming the top layer with the rimmed edge and bottom layer with the headless end of the rivet, and forcing the rimmed edge and the headless end of the rivet to bend radially outward during deformation of the top and bottom layers.
