| <P>PROBLEM TO BE SOLVED: To manufacture an edge protector composed of three dimensional free curved surfaces without raising the manufacturing cost, at excellent productivity and highly accurately. <P>SOLUTION: The edge protector is press-formed by two plastic working stages of a primary plastic working stage where a blank plate is set to a primary press die and the blank plate is drawn into a U-shaped cross-sectional shape by using the primary press die so that the shape of a bending ridgeline is made into a shape which coincides with the shape of the tip edge of the vane body of an object to be attached and a secondary plastic working stage where a primary plastic worked article Wb to which the primary plastic working is applied in the primary plastic working stage is set on a secondary press die 50 and the primary plastic worked article Wb to which stretch-forming is applied by using a secondary press die 50 so that side parts which are continued to the both sides of the bending ridgeline are made into a shape which coincides with a vane-surface shape continued to the tip edge of the vane body in the state where the bending ridgeline part a of the primary plastic worked article Wb is protected from deformation. <P>COPYRIGHT: (C)2009,JPO&INPIT | ||||||

| PROBLEM TO BE SOLVED: To improve a method of manufacturing a metallic sheet member for automotive use from a blank so that cutting work and/or punching work is not required later. SOLUTION: (a) Long sides 8 respectively situated on the opposite sides of the blank 7 are received between the outer lower forming jaws 5 which are situated to face each other, (b) the outer lower forming jaws 5 are moved toward each other and the blank 7 is clamped, (c) the outer upper forming jaws 6 are brought to its closing position and the long sides 8 of the blank 7 are positionally fixed between the outer lower forming jaws 5 and the outer upper forming jaws 6, (d) the outer forming jaws 5, 6 and a pressing tool 2 are relatively moved and (e) the metallic sheet member 17 is finally formed.

| PROBLEM TO BE SOLVED: To briefly remove the strain of a press-formed article only in a tensioning operation in a state (press-forming condition) that the shape of the press-formed article is maintained. SOLUTION: By shifting the center W1 of the press-formed article W in a state that its peripheral edge W3 is fixed by a die 12 of a press unit and a blank holder insert 28 to the press direction (arrow direction in Fig.) in a state of partially pinching the center W1 by a cope 21 and a drag 11, a surrounding portion W2 surrounding the center W1 of the press-formed article W is relatively tensioned in the departing direction from the center W1 and the press-formed article W is deformed and strain is removed from the press-formed article W by the plastic deformation.

| PURPOSE:To control any material to be worked to a proper temperature peculiar to it with a very high precision, by detecting the change of the organization state of the material to be worked, where a temperature change is given, to control the temperature in the warm or hot plastic molding of metallic materials. CONSTITUTION:One end of a material 1 to be worked is fixed by a chuck 2, and the other end is drawn in the direction of an arrow by a chuck 4, and simultaneously, power is supplied directly to the material 1 to be worked through chucks 2 and 4 by a heating power source 8 to heat the material 1 to be worked. When the change of the magnetic permeability of the material 1 accompanied with the rise of temperature is measured by a magnetism detector 11, the magnetic permeability is changed as shown in figure. This detection signal is diffentiated in a magnetism change point detecting circuit 12 to obtain a differential waveform. The occurrence of a rapid magnetism change in the material 1 is confirmed by this waveform, and a temperature T1 detected at this time by a temperature detector 10 is defined as a reference temperature. A slight energy is given to the material 1 properly in low and high speed to set the temperature to a proper temperature T2 for plastic working, and power supply from the power source 8 is stopped to perform the drawing work. | ||||||
