摘要： PROBLEM TO BE SOLVED: To provide low-cost tool steel which has satisfactory workability on working into a die shape, can allow a required part such as a cutting edge to exhibit hardness needed as that of a tool by partial supercooling (subzero) treatment, thus requires no quenching treatment for exhibiting hardness and precision working for removing strains attendant on the treatment, and can simplify a process for producing a die.
SOLUTION: The austenitic tool steel has a composition containing, by weight, 0.6 to 2.0% C, ≤3.0% Si, 0.2 to 15.0% Mn, 0.2 to 10.0% Cr, 0.2 to 10.0% Ni, 0.1 to 4.0% 2Mo+W, and 0.02 to 0.4% S and the balance substantially Fe, and has an austenite content of ≥80% in an ordinary temperature condition after cooling from an austenitizing temperature.

摘要： PROBLEM TO BE SOLVED: To provide a mold for which a manufacturing cost is kept down to achieve its lightweight and to provide its manufacturing method.
SOLUTION: A bottom mold 11 is equipped with a mold structure 20, a mold thickness part 27, and a cavity surface 13. For a method for manufacturing the mold, a space between the first-the fifth plate materials 21 to 25 of the bottom mold 11 comprising the first-the fifth plate materials 21-25 is padded by welding bead 42 to make a mold raw material 71 integrated with the first-the fifth plate materials 21-25. A notch part 46 of the second plate material 22 of the mold raw material 71, a notch part of the fourth plate material 24 and the first-fourth padding parts 43, 47, 51 and 55 are worked by finishing in a specific shape with a cutting tool 72 to expose an end surface of the second plate material 22 and an end surface 73 of the fourth plate material 24 to the cavity surface 13.

摘要： PURPOSE:To subject a work to a sub-zero treatment with the simpler equipment and smaller amt. of liquid nitrogen than in the conventional methods of dipping the work into a cell contg. liquid nitrogen. CONSTITUTION:A flexible pipe 2 is disposed along a part 1a to be subjected to the sub-zero treatment of a work 1 and the liquid nitrogen is discharged from plural discharge holes 2a formed on this pipe 2 toward the part 1a to make sub-zero treatment of the part 1a. Equally good alternative is to execute the sub-zero treatment by depositing a liquid accumulating member absorbing and holding liquid on the part 1a and impregnating the liquid nitrogen into this liquid accumulating member.

摘要： PROBLEM TO BE SOLVED: To quickly manufacture car body panels including trial products to be produced in small quantities by obtaining a blank material by a plasma cutter, performing drawing by a draw metal mold, performing edge cutting and hole boring on a drawing mold by the plasma cutter in the next place, and performing bending molding by a bend metal mold. SOLUTION: This method is suitable for manufacturing car body panels to be produced in small and for manufacturing the trial products of them. Quantities. First or all, a shearing material is obtained from a coil, and is cut by a plasma cuter to obtain a blank material (ST01, 02). The blank material is drawn by a draw metal mold (ST03). A drawing mold is placed on a work placing stand, and edge cutting and hole boring are performed by the plasma cutter (ST04). Bending molding is performed by a bend metal mold (ST05). An obtained car body panel is inspected, and when it is success in an inspection, it is finished, and when it is a failure in the inspection, it is corrected by the plasma cutter in a trim process (ST07, 08). Thus, manufacture of the car body panel can be completed in a short time.

摘要： PURPOSE: To prepare a coolant which can prevent liquefied nitrogen gas from vaporizing and can keep a low temperature for a long period of time by mixing liquefied nitrogen gas and powdered dry ice with stirring under the atmospheric pressure. CONSTITUTION: Liquefied nitrogen gas is poured in powdered dry ice (solidified carbon dioxide) in an amount of 0.7 pt.wt. of the nitrogen gas per 1 pt.wt. of the dry ice and they are stirred. The outlet nozzle for taking out the liquefied carbon dioxide from the vessel filled with liquefied carbon dioxide at 20kg/cm pressure is combined with the outlet nozzle for taking out the liquefied nitrogen gas from the vessel filled with the liquefied nitrogen gas at 5kg/cm and both liquefied gases are simultaneously jetted out into the cooling vessel and they are mixed with stirring.

摘要： PURPOSE:To facilitate machining with securing clearance precision, etc., by forming at least one fitting part of subzero cooling hardener between both of male-female fitting members and treating the fitting part by means of subzero cooling after carrying out clearance adjustment machining in the fixing part under the ordinary temperature. CONSTITUTION:At least a fitting part 4a of one member 4 to the other member between two members, which male-female fits each other, is formed of a subzero cooling hardener A which is hardened by subzero cooling. While the fitting part 4a is roughly machined, one member 4 is fitted to the other member to carry out clearance adjustment machining. Then, a coolant such as snow dry ice, etc., is heaped up on the fitting part 4a so that the fitting part 4a is treated by subzero cooling. In this way, clearance adjustment machining in the fitting part 4a can be carried out easily as the hardness of the subzero hardener A is low before subzero cooling. On the other hand, the hardness of the fitting part 4a is increased by subzero cooling without any distortion and abrasion resistance and clearance precision are secured.

摘要： PURPOSE:To easily and efficiently produce an appropriate amt. of snow dry ice. CONSTITUTION:A CO2 discharge nozzle 5 is provided at one end of a cylindrical vessel 1 with both ends closed, and high-pressure CO, discharged from the nozzle 5 is adiabatically expanded to form snow dry ice (a) in the vessel. The peripheral wall 2 of the vessel is formed with a gas-permeable material, and the air and excess CO2 are discharged to the outside through the wall 2. Consequently, the pressure in the vessel is not increased, and snow dry ice is efficiently formed.

摘要： PURPOSE:To execute sub-zero treatment for cooling a build up welded material joined at the edge part with a cooling material at low cost and in short time, e.g. to form trimming edge on a trimming metallic mold. CONSTITUTION:Rubber magnets 12, 12 are fixed along both side edges in the longitudinal direction of a flexible sheet 1 composed of aluminum wool and a pipe-like vessel 13 formed by mutually attracting both rubber magnets 12, 12 is connected with a liquefied carbon dioxide cylinder and snowy dryice 6 is filled into the inner part. By separating both rubber magnets 12, 12 and attracting to the edge part of the trimming metallic mold 1, the dryice 6 held in the inner part of the pipe-like vessel 13 is brought into contact with the build up welded material 3 in the trimming metallic mold 1 and the welded material is cooled. The pipe-like vessel 13 can repeatedly be used to the trimming metallic mold having various kinds of shapes.
