摘要： PROBLEM TO BE SOLVED: To form a cutting blade at a thin metallic sheet forming an inner blade for an electric shaver only by press working. SOLUTION: At the thin metallic sheet 41, slit holes 42 extending in a direction crossing the sliding direction of the inner blade 4 are blanked at equal intervals. Between a punch die 5 where die bars 51 of inverse-trapezoidal cross sections are arrayed correspondingly to the respective slit holes and a receiving table 6 opposing the punch die, the thin metallic 41 provided with the slit holes is set. Then, the hole edges in the longitudinal direction of the slit holes 42 and 42a are pressurized by the trapezoidal inclined surfaces 43 of the punch die to form the hole edges on the inclined surfaces to form the cutting blade at the lower end edges of the hole edges.

摘要： PROBLEM TO BE SOLVED: To provide a blade with notches with which the reduction of load resistance at the time of cutting can be attained, and to provide its production method.
SOLUTION: The blade 1 is provided with a set of blade members 1A, 1B capable of slidable contact each other, acute-angled edges 3 are formed at the corner parts on both the sides of the sliding-contact parts 2 in the blade members 1A, 1B, respectively, and cutting is performed with the edges 3 by the sliding-contact movement of the blade members 1A, 1B. In the blade 1, a notch 5 is formed at the central part of the sliding-contact face 2 at least in either blade member 1A(1B). The contact area of the blade members 1A, 1B is reduced by the notch 5, thus cutting resistance is reduced.

摘要： PURPOSE:To obtain a sharp cutting tool by rapidly solidifying a molten stainless steel containing specific amounts of Al, forming the resulting metal sheet into cutting tool, and then forming an Al2O3 film with superior adhesive strength on the surface of the cutting tool by means of heating treatment in an oxidizing atmosphere. CONSTITUTION:A stainless steel having a composition containing, by weight, 15-30% Cr, 0-10% Ni, 2-6% Al, and 0.05-1.0% of at least one element among Ti, Zr, Y, Hf, Ce, La, Nd, and Gd is melted, cooled rapidly by a single roll method, a twin-roll method, etc., so as to be solidified into a sheet-like state, and subjected, if necessary, to cold rolling, by which thickness and mechanical properties are homogenized. This stainless steel sheet 2 is formed, e.g. into an outer blade and an inner blade of an electric razor and then heated up to 800-1300 deg.C in an oxidizing atmosphere, by which a thin film 1 of Al2O3 is formed on the surface with superior adhesive strength as if it takes roots 3 in the surface. By this method, the sharp sheet-like cutting tool can be produced.

摘要： PURPOSE:To prevent a drop of strength and a crack-loss of the outside angle of a bent part, by butt-welding a supplementary material onto a line which becomes the outside angle when bending a blank plate, and after that, bend-forming the blank rial plate. CONSTITUTION:On a line which becomes an outside angle when bending a bandlike blank plate 1 obtained by forging, a supplementary material 2 having the same quality as the base material plate 1 is stuck by welding. Subsequently, the blank band 1 is bent to an L-shape by a press machine, etc. Thickness of a bent part of a bent L-shape formed article A beomes a little thicker than thickness of the blank plate 1. A lift pawl B is obtained by cutting an unnecessary projecting part of the outside angle.

摘要： PURPOSE:To manufacture simply drill material with oil holes, by arranging oil-hole packing at prescribed places, where oil holes are formed later, in a hollow cylindrical capsule, and by filling the other place in the capsule with high speed steel powder, then by pressing by a hot hydrostaic press. CONSTITUTION:At prescribed places, where oil holes are formed later in manufacture of a drill, in a hollow, cylindrical capsule 1 are arranged rod materials 2 made of, e.g., copper, copper alloy, or gray cast iron, which melt at a temp. lower than the hardening temp. of the drill and higher than the hot hydrostatic pressing temp. The other part in the capsule is filled with high speed steel powder 3 as drill material. In another case, pipes 4 made of material same as drill material are placed in the capsule and are filled with low-melting alloy of A1, Cu, or Pb, which has no affinity for the pipe 4, instead of above-described metallic rod. Drill mateiral with oil holes is manufactured simply by sintering the capsule with a hot hydrostatic press. The packing is made to melt and run off by heating to a temp. above the m.p. of the packing so as to form oil holes.
