    • The invention comprises a method of forming a sheet metal cup without using a mandrel. A cup shaped blank is first produced having a relief on a rim or outer circumference. The blank is clamped in the spinning machine. The relief controls and facilitates the bending process, creating a uniform curve at a predetermined bending point. During the rolling process, a forming roller is engaged with rim, and is moved progressively parallel with an axis of rotation. As the forming roller moves, the rim is progressively bent from an orientation normal to an axis of rotation to a position parallel to the axis of rotation. The fully formed rim can then be punched to accommodate a bearing or shaft. This allows a small radius pulley to be formed without use of a mandrel.
    • 本发明包括在不使用心轴的情况下形成钣金杯的方法。 首先制造出杯形坯料,其在边缘或外圆周上具有浮雕。 坯料夹在纺纱机中。 浮雕控制并促进弯曲过程,在预定的弯曲点产生均匀的曲线。 在轧制过程中,成形辊与轮辋接合,并且与旋转轴线逐渐平行移动。 当成型辊移动时,边缘从垂直于旋转轴线的方向逐渐弯曲到平行于旋转轴线的位置。 然后可以将完全成形的轮辋冲压以适应轴承或轴。 这允许在不使用心轴的情况下形成小半径滑轮。

    • A cylindrical workpiece (20) is mounted onto and connected to a mandrel (14) that is itself mounted for rotation about a vertical axis (12). A first end portion of the workpiece (20) is housed within the mandrel (14). A second end portion projects axially outwardly beyond a radial forming surface (60) on the mandrel (14). A first forming roller (30) is mounted on a swing post (52) that is positioned by an adjustable length strut (56). The strut (56) is elongated to swing the post (52) downwardly and place the roller (30) inside the second end portion of the workpiece (20). Then, a lead screw (28) is used for pulling on a base (50) that supports the post (52). This pulls a convex face portion (32) of the roller (30) against the inside of the second end portion of the workpiece (20). Lead screw operation moves the roller (30), causing it to stretch the second end portion of the workpiece (20) and move it up onto and then move it radially outwardly along the forming surface (60). The movement of the roller (30) can be stopped before the roller (30) passes the outer diameter of the forming surface (60). Then, a second forming roller end cam can be used to bend the outer end part of the workpiece radially inwardly and then flat against an adjoining portion of the workpiece (20) that is in contact with the forming surface (60). Or, the roller (30) can be moved radially outwardly until it moves past the outer diameter of the forming surface (60). At that time, stored spring energy will push the roller (30) downwardly at it is still moving outwardly, so as to form a V-groove (36) in the workpiece (20). Then, second and third rollers (40, 44) may be used for curling the end portion of the workpiece over and back towards the forming surface (60) to form a bead (B) on the outer periphery of the workpiece (20).

    • To spin a metal sheet around a chuck for forming a product, in a teaching phase involving force control, a product is formed on the chuck by rotating the chuck about the axis of rotation and by moving a forming roller one or several times alongside the chuck with a pre-determined pressure force thereby spinning the intermediate metal sheet. In the teaching phase, measuring data corresponding to the movement of the forming roller during spinning is fixed in a memory of a control unit, and in the production phase the forming roller is controlled with the aid of these measuring data. The control unit determines the position values of the forming roller in axial direction and in transverse direction relative to the chuck from the data fixed in the teaching phase, and the control unit controls the forming roller in the production phase at least during a part of the spinning movement by means of the position values determined in this manner for spinning the metal sheet into the desired product.

    • Method and apparatus for spinning a product, wherein a metal plate which may be preshaped or not, is deformed on a rotating chuck by a forming roller into a hollow product with a wall thickness. The shape of the chuck is determined and is stored in a memory of a control unit as a series of successive points. The control unit moves the forming roller according to a path corresponding with the shape of the chuck. This path is determined by the stored shape of the chuck with a desired wall thickness of the product added thereto. The metal plate is deformed by moving the forming roller according to the thus determined path. In each point of the stored shape of the chuck, the control unit determines a tangent line of the chuck shape at the location of this point and adds the desired wall thickness to the chuck shape at the location of this point according to a line perpendicular to the tangent line to calculate the path of the forming roller.

    • A method for making seamless tilted vent comprises the spinning of a mold and a metal sheet to form a tubular member and a flat angular shackle continuously extending from and around the tubular member. The mold is made of a cylindrical member and a flat collar surrounding the cylindrical member at one end. The collar is agularly disposed relative to the cylindrical member and the metal sheet is tightened in abutting relationship against the other end of the cylindrical member. The spinning takes place about an axis corresponding to the longitudinal axis of the cylindrical member. The chasing operation of the metal against the cylindrical member is made until the metal sheet reaches the intersection of the cylindrical member with the collar to form a tubular member. The speed of the mold and of the tubular member is then set between a maximum speed not exceeding 400 RPM and short intervals of speed substantially reduced from said maximum speed. During the above sequence of speed, the metal sheet is alternatively chased until it abuts against the collar for forming the angularly disposed shackle.
