Abstract: A product including a top surface part, a vertical wall part connected to an end of the top surface part and a corner part interposed between the top surface part and the vertical wall part is manufactured by flowing a material of the corner part toward the top surface part while applying a pressing force on a workpiece.

Abstract: A side panel including a first member and a second member having a higher strength is manufactured by arranging a corner portion of the second member in a recessed portion of the first member, and by simultaneously press-working the first member and the second member.

Abstract: A cutting apparatus is provided with a first blade (48, 82), a second blade (50, 84) intersecting with the first blade (48, 82), and a switching unit (72). The switching unit (72) switches between a first mode and a second mode. In the first mode, the first blade (48, 82) positions in a cutting position in which it is possible to cut a work-piece (12) and the second blade (50, 84) positions in a non-cutting position in which it is impossible to cut the work-piece (12). In the second mode, the second blade (50, 84) positions in the cutting position in which it is possible to cut the work-piece (12) and the first blade (48, 82) positions in the non-cutting position in which it is impossible to cut the work-piece (12).

Abstract: A vehicular body panel or component part having a reinforcing backing plate reconciled or joined to a part of a blank material at a position wherein a bending formation is implemented. The backing plate has one or more apertures formed in at least one lateral row at a location equivalent to the position of the bending formation. When forming the blank material and the backing plate concurrently by a bending operation, the backing plate becomes intimately associated with the blank sheet to avoid the backing plate from locally separating from the blank material and from forming a gap relative thereto, with a resultant improved product quality.

Abstract: A rolling apparatus is disclosed which forms a thin walled portion on part of a steel strip by allowing the steel strip to intervene between a pair of upper and lower rolling rolls, in which the upper rolling roll is vertically movable. The steel strip which has been pressed between a pair of upper and lower rolling rolls is repeatedly moved on a traveling table to upstream side and downstream side alternately, thereby forming the thin walled portion having a width corresponding to the movement quantity. In forming the thin walled portion, the steel strip is grasped on both upstream side and downstream side with a plurality of clamping means and is subjected to a tension due to tension imparting means, thereby facilitating formation of the thin walled portion.

Abstract: A vehicular body panel or component part having a reinforcing backing plate reconciled to a part of a blank material at a position wherein a bending formation is implemented. The backing plate has one or more than two apertures formed in at least one lateral raw at a location equivalent to the position of the bending formation. When forming the blank material and the backing plate concurrently by bending operation, the backing plate becomes intimate with the blank sheet to avoid the backing plate from locally separating from the blank material and from forming a gap relative thereto, with a resultant improved product quality.

Abstract: An apparatus for cutting a piece of work has a work supporting table which is movable only in one horizontal direction, and a spindle unit including a cutting tool which is disposed below the table for cutting the work from below. The spindle unit is movable in another horizontal direction perpendicular to the direction in which the table is movable, and in a vertical direction. The apparatus requires only a small space for installation, is simple in construction, an can perform an accurate cutting job at a high speed.

Abstract: A pit defining a machining cavity is positioned downstream of a loading conveyor. A workpiece such as a foam block to be machined into a lost foam pattern for use in full-mold casting is fixedly mounted on an invertable workpiece mount base that is positioned above the machining cavity. The machining cavity houses a cutting unit for cutting, from below, the foam block supported on the workpiece mount base. Chips produced when the foam block is cut by the cutting unit are discharged by a chip discharger disposed beneath the machining cavity. The machining cavity can be substantially closed by the workpiece mount base or the foam block mounted thereon. There may be employed upstream and downstream machining stations each having the machining cavity, the workpiece mount base, and the cutting unit. The workpiece mount base in the upstream machining station is vertically movable, and the upstream and downstream machining stations are interconnected by transfer units.
