摘要： Disclosed is an adjustable internal support restraint device for roundness control of a cabin component. The present disclosure solves the problem that the existing cabin components are prone to roundness distortion in a heat treatment process. The adjustable internal support restraint device includes a central limiting column and at least two circumferential ejecting correcting assemblies that are coaxially mounted on the central limiting column in a sleeving manner. Each circumferential ejecting correcting assembly includes a mounting piece and a plurality of ejector blocks. The mounting piece is mounted on the central limiting column in a sleeving manner. The plurality of the ejector blocks are annularly arranged outside the mounting piece and are in threaded connection with the mounting piece. One side surface, close to the inner cavity profile of a cabin, of each ejector block and the inner cavity profile of the cabin are arranged according to the shapes.

摘要： A method for forming a metal beam may comprise: clamping first and second portions of the metal beam in a substantially fixed and in a position whereat the metal beam is rotatable about three axes; applying a net bending force to the clamped second portion of the metal beam at a predetermined angle; sensing twisting of the second portion of the metal beam resulting from the net bending force; and modulating the angle at which the net force is applied to reduce the twisting of the metal beam. As a result, the net bending force is moved toward the shear center and toward being along the principal axis of the metal beam.

摘要： A pipe-bending apparatus comprises an elongate structure having a longitudinal work surface at, or adjacent to, opposite ends of which clamping means and a former are respectively mounted. The former is held fast on the work surface, and the clamping means is power-driven towards and away from it by a double-acting hydraulic ram. A series of formers are provided, each having, in plan, a semi-circular anvil mountable to face the clamping means. The anvils are each of concave vertical cross-section and of different radius from one another, with peripheral walls to locate a pipe in position in the anvil during a bending operation. The ram is supplied from a tank containing a hydraulic fluid tank which--together with the necessary hydraulic pump and electric motor--is mounted beneath the work surface.

摘要： To fabricate a bent assembly of two metal tubes with one extending through and radially spaced within the other, the bending is done by inserting the smaller through the larger tube producing a tubular work assembly, clamping a leading work portion onto a bending forming die with the inner tube eccentric in the region to be bent against the die-adjacent inner wall portion of the outer tube, bending the region trailing the clamped portion by wrapping onto the bending die, while at (and immediately preceding) the point of feed onto the die the tubes are supported against collapse by a cylindrical mandrel in the smaller tube and a mandrel of crescent cross-section interposed between the large and small tube, in the plane of bending providing reaction support by a slideshoe bearing against the outer tube diametrically remote from the die; the mandrels being axially shiftably supported.

摘要： An apparatus includes a guide member configured with stress limiting features which function to prevent the stress from bending the guide member causing ovalization of the guide member. An apparatus for bending a guide member includes a ram die and a pressure die which are configured to fully encircle the portion of the guide member during the bending operation. A fixture for supporting a guide member during bending is configured to fully encircle sections of the guide member during bending.

摘要： A bending apparatus for rod-shaped and tubular workpieces, includes a rotatable bending mandrel with a bending groove is provided with a wrinkle smoothener, which immediately precedes the bending mandrel, and two sliding jaws. In order to change the bending direction around the bending mandrel, the sliding jaws can be moved to the other side thereof. In doing so, the sliding jaw on the side of the bending mandrel is arranged freely rotatable on a support axis, which extends parallel to the axis of rotation of the bending mandrel and whose position relative to the bending mandrel can be shifted parallel to the feeding direction of the workpiece. The sliding jaw is provided such that the end of its forming groove facing towards the bending mandrel can be placed in contact with the bending groove by shifting the support axis and, thus, its forming groove tangentially joins said groove.
