摘要： Hardening is accomplished by heating a longitudinal section of a workpiece such as an odd-shaped bar, and by quenching while constraining the workpiece section in dies. The quenching is executed while the workpiece is pressed in a direction perpendicular to its longitudinal direction by a pressing device which is installed adjacent to the workpiece section constrained in the dies. Warping by quenching can thus be minimized in odd-shaped workpieces, such as an automobile steering rack bar.

摘要： This invention provides a method and apparatus for quenching a tubular workpiece such as cylindrical tubes or different-shaped tubes, which are difficult to be exerted constraining force for preventing warping especially in case of thinner thickness. Warping is prevented by applying a constraining force which is increased from beginning of the quenching to termination thereof, corresponding to increase of elasticity limit stress in accordance with temperature drop of the workpiece. Furthermore, apparatus for carrying out the method for quenching a tubular workpiece are offered, wherein the apparatus are provided with a pressure controller for pressure rolls or dies, thereby the pressure controller changes setting input for the pressure during the quenching.

摘要： A constrained quenching apparatus is provided for hardening a workpiece such as an asymmetrical bar which has a notable tendency to warping when quenched, without warping the workpiece. The apparatus comprises a set of two or more dies having plural projections provided on the inner side thereof, the projections coinciding with the contour of the workpiece when the dies are closed so that their die faces in contact with one another, and having plural recesses therein defined by the projections. The recesses are provided with one or more cooling liquid blow holes. The apparatus does not exert pressure on the workpiece at the start of the quenching when the workpiece is soft, so the flattening of the hollow workpiece such as a pipe, can be prevented.

摘要： The present invention is drawn to a method and apparatus for holding wire at a specified temperature for a specified period of time by a direct-resistance heating device which applies such voltage as to generate Joule's heat in the wire, sufficient to offset the quantity of heat that would tend to be released from the heated wire during unforced cooling, after the travelling wire is heated rapidly to a specified temperature throughout its cross section. A temperature-holding apparatus, employed subsequent to the heating of wire, may either supply power directly to a wire through feeding wheel electrodes or entail a combination of a shell type transformer and a hollow annular holding furnace incorporating guide rollers, and having wheel electrodes electrically connected by a lead, disposed outside of the inlet and outlet of the holding furnace incorporating guide rollers, and producing secondary current in the multiple-wound wire in the furnace with the lead as a return, depending upon the holding time desired. The latter form of the apparatus imparts an advancing force and curl to the wire so that thick and inflexible wire can be placed in the holding furnace, and rollers are provided to create a desired number of turns in the wire in the holding furnace.

摘要： A spacer 44 is inserted between an upper end face 44a of a contact column 40, and a lower face of a flange 14. The flange 14 is supported at plural positions by supporting columns 42. In heating a shoulder portion 16 to a hardening temperature, an electroconductive member 56 is placed close to the shoulder portion 16, and an AC current having a frequency which will cause mutual attraction between the current flowing through the elctroconductive member 56 and the current flowing through the shoulder portion 16 is applied to flow through the electroconductive member 56. The shoulder portion 16 having been heated to the hardening temperature is quenched by ejecting a liquid coolant through ejection outlets of a cooling jacket.

摘要： A liquid phase diffusion bonding method for dissimilar metal sheets of the present invention has the steps of: allowing a galvanized steel sheet and an aluminum alloy sheet to come into close contact with each other and pressing both sheets by using a first mold of a liquid phase diffusion bonding apparatus and a second mold of the same; and heating the galvanized steel sheet and the aluminum alloy sheet at approximately the same heat-up rate and at approximately the same temperature to perform liquid phase diffusion bonding of the sheets by using induction heat generated by applying high frequency currents to a first high frequency induction heating coil provided on the first mold and a second high frequency induction heating coil provided on the second mold. The first high frequency induction heating coil and the second high frequency induction heating coil are positioned to sandwich the galvanized steel sheet and the aluminum alloy sheet at predetermined distances from the sheets, respectively. By this method, it is possible to reduce a time for bonding the galvanized steel sheet and the aluminum alloy sheet and to ensure sufficient bonding strength between the sheets.
