摘要： A counterweight loading and unloading device and a movable crane have a freestanding pallet (10) with two ends whose upper end faces are used for holding a counterweight (61). The two ends of the freestanding pallet (10) are both equipped with a cavity, and at least one telescopic oil cylinder (11, 12, 13, and 14) is provided in the cavity. A fixed end of the telescopic oil cylinder is fixed with the freestanding pallet (10), and a telescopic end of the telescopic oil cylinder is coupled with a pallet lifting mechanism for lifting the freestanding pallet. The device is not limited by a planar space of a vehicle frame and a turntable height of the movable crane. An integral dimension of the movable crane is not increased, thus preventing integral dimension of the movable crane from exceeding a road traveling standard. The structure of the device is more compact, and the telescopic oil cylinder plays a role of the counterweight, thus enabling stress of the turntable to be more reasonable.

摘要： According to at least one aspect of the present invention, a method is provided for cladding a thin metal sheet for enhanced formability and manufacturability thereof. In at least one embodiment, the method includes contacting at least one metal cladding layer with the thin metal sheet to form a thin metal sandwich having an original thickness, wherein the metal cladding layer may be a thin metal foil or a plated or deposited thin metal film, and then subjecting the thin metal sandwich to four Skin-Pass steps at an incremental thickness reduction ratio of 25 percent of the total thickness Reduction Ratio per step in four alternating directions. The method provides Skin-Pass processed clad sheet metals with reduced uniaxial pre-strain, improved uniformity in microstructure and material properties along the longitudinal and transversal directions, and enhanced formability and manufacturability.

摘要： A single-step heat treating and surface coating process is provided for steel self-piercing rivets for joining 5xxx and 6xxx aluminum panels. In this process, two coats of zinc and aluminum flakes in an inorganic binder are applied to the steel rivets. After each coating, the rivets are heated to set and cure the coats and to achieve the desired microstructure and hardness level for joining 5xxx and 6xxx aluminum panels. The coating curing step combines the heat treatment with surface coating into a single-step procedure.
