摘要： A friction stir spot welding apparatus including a controller that (A) operates a rotary driver and a tool driver such that a pin and a shoulder are brought into contact with a welded workpiece; (B) operates, after the (A), the rotary driver and the tool driver such that the pin separates from the welded workpiece; and (C) operates, after the (B), the rotary driver and the tool driver such that the pin advances toward the welded workpiece. The controller controls the tool driver such that pressing force applied to the welded workpiece from the pin and the shoulder in the (C) is smaller than that in the (B) and/or controls the rotary driver such that rotational frequencies of the pin and the shoulder in the (C) are lower than those in the (B).

摘要： A roll bending apparatus includes: a roll pair formed by a pair of rolls disposed facing each other, the roll pair being configured to sandwich an elongated material between the rolls to perform forming on the elongated material; a slide mechanism configured to slide the roll pair in a first normal direction that is a direction normal to a conveying direction of the elongated material on a plane including the conveying direction; and a tilt mechanism configured to rotate the roll pair about a tilt axis that extends in a second normal direction that is a direction orthogonal to the conveying direction and the first normal direction. The slide mechanism further slides the roll pair to change a position of the roll pair relative to the tilt axis.

摘要： Forming roll units included in an apparatus for manufacturing a roll-formed component each include a roll pair. The roll pair includes a receiving roll part and a first bending roll part that face each other. A plate member passing area is formed below the first bending roll part, the plate member passing area allowing a roll formed member excluding its side edge portions to pass through. The roll pair is configured to make, during bending, sliding movement in a width direction of the roll formed member and rotational movement about a normal direction to the roll formed member as a rotational center.

摘要： A friction stir spot welding apparatus according to the present invention includes: a rotary tool; and a perpendicular-to-plane detector, which detects whether or not the rotary tool is positioned to be in a perpendicular-to-plane state relative to a joining target portion of workpieces. The perpendicular-to-plane detector measures distances to at least three measurement positions set around the joining target portion by means of, for example, position sensors. The measurement positions are set to be positioned at the vertices of a polygon on a reference plane to which forward and backward movement directions of the rotary tool are normal. The perpendicular-to-plane detector detects that the rotary tool is positioned to be in the perpendicular-to-plane state relative to the joining target portion of the workpieces if all the distances to the measurement positions are equal to each other.

摘要： Friction stir spot-welding is performed to join together a stack of a plurality of metal foils and a metal sheet by using a double-acting type rotary tool including a hollow member and a pin member which are movable independently of each other in their axial directions, and a clamp member which is fitted on an outer circumferential surface of the hollow member and which is movable in its axial direction. While an outer annular part of a portion to be friction-stirred is pressed with the clamp member, the pin member is inserted into the above-described portion and the hollow member is retracted, whereby a metal mass is accommodated within a space formed between the above-described portion and the hollow member. Then, the hollow member is advanced to press the metal mass into a hole formed by retraction of the pin member, whereby the hole is filled with the metal mass.

摘要： A friction stir welding apparatus is used at a butted portion where a second workpiece is butted against a first workpiece such that the second workpiece is upright on the first workpiece. The friction stir welding apparatus includes: a rotary tool that is plunged into one inner corner of a pair of inner corners that are positioned, at the butted portion, on both sides of the second workpiece, respectively; an inner corner presser that presses the other inner corner of the pair of inner corners; and a mover that moves the rotary tool and the inner corner presser along a direction in which the butted portion extends. The inner corner presser includes a pressing roller that presses the other inner corner while rolling in a state where the inner corner presser is being moved by the mover.

摘要： There is provided a press brake that improves bending accuracy of a partial bending method. The press brake includes: a conveying mechanism that intermittently conveys a workpiece; a die; a punch; a crowning mechanism; a bending amount measuring device; and a control device. The control device presses an end portion of the workpiece in a conveying direction by the punch and conveys the workpiece by the conveying mechanism until the pressed portion enters into a measurement range of the bending amount measuring device. The control device drives the crowning mechanism so as to correct a crowning amount in accordance with a difference between a middle bending amount and an end bending amount measured by the bending amount measuring device.
