An apparatus for correcting an aberration in a bullet casing's neck, the apparatus incorporating a support frame; a collet chuck and collet sleeve combination whose collet chuck presents a circumferential array of jaws having longitudinal ends, wherein the collet chuck further has a throat extending longitudinally from the jaws' longitudinal ends; a bullet ogive centering annular land fixedly attached to or formed wholly with the collet chuck, the bullet ogive centering annular land being positioned at an oppositely longitudinal end of the throat; rotatable mounting conical bearings and bushings which attach the collet chuck and collet sleeve combination to the support frame; and a turn wheel connected operatively to the collet chuck and collet sleeve combination.

The present disclosure provides a floating block of a hub shaping mold. The floating block can include: at least one inner support member having a first side and a second side opposite to each other, wherein the first side of the at least one inner support member can include a first arc surface, and at least one first bulge can be arranged on the first arc surface; at least one outer pressing member having a first side and a second side opposite to each other, wherein the first side of the at least one outer pressing member can include a second arc surface matched with the first arc surface, at least one second bulge can be arranged on the second arc surface, and the at least one first bulge and the at least one second bulge can be arranged in a staggered manner.

Roll forming is used for re-shaping an iridium crucible. The crucible is placed on a platen. The platen rotates the crucible while heat is applied by a plurality of torches. A plurality of rollers press on the rotating, heated crucible to re-shape. The roll forming allows for a greater number of repetitions of the re-shaping, increasing the number of uses per expensive re-fabrication of the crucible. The roll forming may provide more exact re-shaping.

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.

Device (1) for calibrating and straightening hollow components, preferably welded pipes (2), the device (1) being substantially composed of a frame (5) having two side stands (6, 7), a lower cross member (8) and an upper cross member (9), a ram (10) being provided, said ram (10) being movable toward the lower cross member (8) and back by means of a pressure-operable cylinder assembly (12) supported on the upper cross member (9), and a calibrating and straightening tool (11a) being provided between the lower cross member (8) and the ram (10), wherein the calibrating and straightening tool (11a) is changeably disposed on the lower cross member (8) and on the ram (10) and can be replaced with a bending tool (11b) for bending the lateral ends (3) of sheets (4) to produce pipes (2).

A shaping method for a double pipe includes: bending the double pipe with a specified curvature to form a bent portion in the double pipe; and arranging the bent portion on a first shaping die having a first shaping surface at a position biased inward or outward in a curvature radius direction of the bent portion relative to the first shaping surface, wherein the first shaping surface is configured to shape a first outer surface of both outer surfaces of the bent portion that are located on both sides of a plane including a central axis of the bent portion, and pressing the bent portion arranged on the first shaping die by a second shaping die having a second shaping surface configured to shape a second outer surface of the both outer surfaces of the bent portion.

An apparatus for the orbital cutting and calibration of tubes is provided. The apparatus has a rotor having a central hole through which a tube to be cut is movable along its longitudinal axis, the rotor being drivable to rotate about a first axis of rotation coinciding in use with the longitudinal axis of the tube that is supplied to the apparatus. The apparatus has a cutting device having a first support body mounted radially movable on the rotor and a cutting tool carried by the first support body, and a calibration device having a second support body mounted to be radially movable on the rotor and a calibration tool carried by the second support body.
