摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a press die which helps to shorten the manufacturing time of a die as much as possible. SOLUTION: In a condition that a platy metallic material 16 is supported by a supporter 12, a forming tool 20 with a substantial point contact to the platy metallic material 16 is transferred to the inside of the horizontal surface along the contour line of a product to deform the platy metallic material 16 plastically. By gradually changing the contour line for a target manufacture, a model panel 22 substantially identical to the configuration of the final product is obtained. The model panel 22 is located in a standing position inside a casting die frame 24 and the molten metal material for pressing mold is poured to both the surface and the back of the model panel. By solidifying the molten metal, a punch and a die of the press die is attained.

摘要： PROBLEM TO BE SOLVED: To provide a male forming method which restricts droop and deformation of a forming goods. SOLUTION: An outer circumference frame 2 is attached to the circumference edge part 2 of a base plate 1, and a supporting tool 3 is mounted on the central part of the base plate 1. Further, a metal sheet 4 is held on the upper face of the outer circumference frame 2 with bolts 10 so that the metal sheet 4 is brought into contact with the peak of the supporting tool 3. A set of jigs in this state is fixed on a table of an NC vertical milling machine. Next, based on a forming contour data assembled with a male die working contour data and a circumference working contour data, a tool 5 is moved so as to alternately repeat circumference forming and male die forming, the metal sheet 4 supported with the supporting tool 3 is formed with pressing from the upper side by every one layer or every plural layers, and formed into the male die shape. In this time, the tool 5 is always moved from the range of outskirts of the outer circumference frame 2 toward the center.

摘要： PURPOSE:To keep the high strength of a joint in the wide current range by using the iron/aluminum clad of the prescribed ratio of the thickness of a sheet made of aluminum to that of the steel sheet. CONSTITUTION:A galvanized steel sheet 1 is arranged on the iron side c>f a clad sheet of double layer of iron/aluminum made of a cold-rolled steel sheet 3 and an aluminum sheet 4, and an aluminum sheet 2 is arranged on the aluminum sheet 4 side to execute the spot welding. The iron/aluminum clad sheet where the ratio of the thickness of the aluminum sheet to that of the steel sheet is 1:1.3-1:5.0 is used, and the welding is executed under the condition where the welding current is 7.5-15.5A, and the welding time is 80-280ms. This constitution suppresses the deposition of the aluminum and the plating to the minimum, and high strength of the joint can be secured.

摘要： PURPOSE:To carry out a high quality welding by applying a high density current between a plated steel material and a clad material in a resistance welding method being suitable to a spot welding between the steel material executing a corrosion preventing treatment, etc., with a plating work and an aluminum base material. CONSTITUTION:The clad material 15 composed of an iron layer 15a having projecting parts 15c and an aluminum layer 15b is interposed between the plated steel plate 13 as a material to be welded and the aluminum steel plate 14. A specified current is applied to the electrodes 10, 11 from AC electric source 15b. Electric conducting passage of the welding current is limited to the area of the projecting parts 15c, and as molten plating metal by melting the plating layer 13a is incorporated among the pitches of the projecting parts 15c, the enlargement of the electric current conducting area is prevented. In this result, the temp. of the interface between the plated steel plate and the clad material is efficiently raised and the suitable nugget is formed to both surfaces of the clad material 15.
