摘要： PURPOSE:To manufacture simply a hollow part having a stepped part on the outer periphery by rotating a columnar material and pressing with three forming rolls provided in circumference and piercing a hole at the center of the material by a rotary mandrel. CONSTITUTION:Both end faces of a columnar steel material 45 are supported by flanges 26, 26a, and three forming rolls 20 are arranged around them. While rotating the material 45, mandrels 27, 27a are advanced through holes provided in the center of flanges 26, 26a, and a hole is pierced along the center axis of the material 45. At the same time, rotating three forming rolls are pressed down against the outer peripheral face of the rotating material 45 to form a necessary stepped part on the outer peripheral face of the material 45. By this way, a hollow part having stepped part on the outer periphery can be manufactured by small number of stages and man-hours.

摘要： PURPOSE:To perform diffusion joining of multilayer cylindrical bodies effectively and surely by pressing the outside circumferential surfaces of the joined members by acting gaseous pressure thereby pressure-welding the fitted surfaces of the cylindrical bodies. CONSTITUTION:A sealing plate 1 is brazed to the top and under end face parts of the fitting surfaces 6 of an outside cylinder 4 and an inside cylinder 5 in a vacuum. The assembly of these two layer cylinders 4, 5 and sealing plate 1 which are brazed to one piece is put into a device that can apply gaseous pressure and temp. simultaneously, in which it is applied with gas pressure while being maintained at a diffusion joining temp., whereby the fitted surfaces 6 are diffusion- joined. The application of the gaseous pressure causes the inside cylinder 5 to elastically deform in a diameter expanding direction and the outside cylinder 4 in a diameter reducing direction and therefore the joined surfaces are pressure-welded and are diffusion- joined. Compressive stress is generated by the gaseous pressure acting upon the contact surfaces of the top and under end faces of the sealing plate 1 and the two layer cylinders 4, 5, so that the diffusion joining treatment is accomplished in the normal pressure-welded state of the fitted surfaces as well without the entry of brazing metal between the contact surfaces.

摘要： PURPOSE:To readily volume-produce fins for heat exchangers by forming rugged parts assuming roundness on both edges of a metal plate material by hole type forming rolls, and cutting away the concave connecting parts of the convex parts by a cutting roll then bending square the thus formed bar-shaped bodies. CONSTITUTION:A metal plate 2a is formed continuously with convex parts 3a' on both edges, leaving a land 2b in the center, by a pair of upper and lower hole type forming rolls 11, 11. Next, the concave parts connecting the convex parts 3a' are cut away by a cutting roll 13 and a flat roll 14, and the convex parts 3a' are formed into bar-shaped bodies 3a. These are admitted into a bending device 16, where the bar-shaped bodies 3a are bent square with respect to the land 2b in the central part, whereby fins 3 are formed. The fins for heat exchangers of various kinds of air conditioners etc. may be easily volume-produced by this method.

摘要： PURPOSE:To improve the yield of material at head and tail ends of the rolled material, by setting the roll gap at a size larger than the roll gap of the final roll, and by reducing the roll gap to the size of the final rolls' just at starting the rolling work, and by performing the rolling work. CONSTITUTION:At edging the metallic material, first of all, the gap of the rolling roll 2 in the breadth direction is set at the size of the roll gap for the initial rolling reduction. The initial rolling reduction is represented by DELTAh1=R(1-costheta) (in which, R is the roll's radius and theta is the angle of bite under the initial reducing condition), besides, the relation 2DELTAh1>=rW0 (in which, W0 is the sheet breadth before the rolling work, and (r) is the breadth reducing rate) is established. After the rolling work is started, at the point of time that the rolled material's tip passes the center of the roll 2, the screw down device of the roll 2 is driven to reduce the roll gap to the final reducing gap according to the signal of the detector so as to satisfy the relation, that is the roll gap reducing time T=(aW0)/V (in which, (a) is the value obtained by dividing the slab length required in reducing the rolling reduction from DELTAh1 to DELTAh2 by the sheet breadth W0, and V is the circumferential speed of the roll 2); hereby, the purpose can be accomplished.

摘要： PURPOSE:To manufacture spiral parts decreasing mon-hours of working and increasing material yield by performing plating of required strength on the surface after forming spiral parts by extrusion using Al as a material. CONSTITUTION:Spiral parts 1' are formed by extrusion using Al as a material. In this case, forming is made to smaller size by the thickness of a plating layer in consideration of subsequent platings. Iron is plated to specified thickness on the surface of extruded Al parts. Thus, hardness similar to steel parts can be obtained.

摘要： PURPOSE:To perform die forging of a molding having an intricate shape without producing under fill and burrs by forming roughly the top and bottom of a blank material with top and bottom dies, forming roughly the side faces with side dies, and pressing the blank material in a closed state with punches to pack the same in the closed space. CONSTITUTION:A closed forging die is constituted of top and bottom dies 10, 11 which define the shape of the top and bottom surfaces of a molding 1 and plural divided side dies 12, 13, 14, 15 which are positioned between the top and bottom dies and define the shape on the side faces of the molding. The top and bottom surfaces are roughly formed and the side faces are roughly formed, by which the forging die closed with the dies 10, 11, 12, 13, 14, 15 is obtd. The roughly formed material is pressed with punches 16-19 through any of the dies to pack the blank material in the forging die. Thus, the die forging is accomplished.

摘要： PURPOSE:To obtain an impeller at a low cost with a less stage in the stage of extruding and forging radially vanes by using punches, by giving twist to the punches to incline the vanes in the stage of drawing the punches forced into the blank material in a bottom die. CONSTITUTION:A blank material 3 for an impeller 3 is fitted into a bottom die 9, and a top die 12 is lowered to force radially projected punches 11 into the material 3, thereby radially extruding respective vanes and yielding an impeller 4 arranged alternately with large and small plane vanes. Shaft grooves for twisting are provided at the top end in a shaft part. The impeller 4 is then fixed together with the die 9 by means of a chuck 10, and the die 12 is moved and rotated to twist the punches 11 while drawing the same from the impeller 4, by which the vanes 6 are inclined in the same direction and the impeller 5 is obtd. The chuck 14 of the die 12 is fitted in the shaft grooves in this stage to twist the shaft part to the same degree as for the vanes. Mass production of the impeller having an intricate shape is thus made possible.

摘要： PURPOSE:To enable rotary forging that meets the shape of a work by providing a required number of punches which position the top or bottom die of a press to the holders of the top or bottom die of a press and inclining the opposing surfaces of the respective holders at optional angles relatively with each other. CONSTITUTION:Four punches 12-A, B, C, D are connected, via universal joints 13, to a top die 11, and are constituted vertically individually movably as desired by oil pressure. The punches 12-A, B,- are controlled so that the die 11 has an attitude (a) inclining downward toward the left to form a work X. The die 11 is thereafter brought into the state (b) inclining downward toward the right and to a horizontal state (c) to form successively the work X. The contact area between the forged article and the die is thus decreased in performing forging, and the number of the punches 12 is enough if it is >=3 pieces. Rotary forging of a large-sized forged article to a desired shape is thus made possible by using a press having relatively small forging capacity.
