As the upper mold 14 descends as described above, the first rail 114a and the second rail 114b are also lowered, and the first roller 134a is lowered as the first rail 114a and the second rail 114b are lowered. ) And the second roller 134b are transported along the first tapered portion 116a and the second tapered portion 116b to the upper portion of the first tapered portion 116a and the second tapered portion 116b. In this way, the first roller 134a and the second roller 134b are transferred to the upper portions of the first tapered portion 116a and the second tapered portion 116b, and the movable portion 130 pressurizes the return spring 126 while pressing. To the government 160 side. At this time, the workpiece material caught on the first fixing protrusion 148a, the second fixing protrusion 148b, the third fixing protrusion 178a, and the fourth fixing protrusion 178b of the movable unit 130 and the fixing unit 160 ( 10 moves forward together to the fixed portion 160 by the forward movement of the movable portion 130, the workpiece 10 fixed in the fixed portion 160, the third clasp 176a and the fourth clasp 176b. 3) the third fixing protrusion 178a and the fourth fixing protrusion 178b of the fixing portion 160 are moved forward while pushing the upper portion thereof to the outside of the fixing portion 160, and the other position of the workpiece 10 is advanced. It is inserted into the crystal hole 12.

On the other hand, when the upper mold 14 is raised, the first roller 134a and the second roller 134b are formed along the first tapered portion 116a and the second tapered portion 116b and the first tapered portion 116a and It is conveyed to the lower part of the 2nd taper part 116b. In this way, the first roller 134a and the second roller 134b are transferred to the lower portions of the first tapered portion 116a and the second tapered portion 116b, and the movable portion 130 is returned by the return spring 126. At this time, the first fixing protrusion 148a and the second fixing protrusion 148b of the movable part 130 return while being separated from the positioning hole 12 of the advanced work material 10, thereby positioning another positioning hole 12. Is inserted into At this time, the fixing part 160 prevents the workpiece 10 from moving in the reverse direction by the returning movable part 130.

As described above, the material transfer apparatus 100 for a press die according to the present invention includes a first rail 114a having a first tapered portion 116a and a second tapered portion 116b formed on one side of the upper mold 14. A first roller 134a having a cam 110 having a second rail 114b and disposed on the front surface of the cam 110 to be transported along the first tapered portion 116a and the second tapered portion 116b. And a second roller 134b and disposed on the front of the movable part 130 and the front of the movable part 130 in which the movable block 140 for discharging the processed material 10 into the upper part is disposed. The upper portion is provided with a fixing portion 160 is disposed on the fixing block 170 for discharging the processing material 10 discharged from the movable block 140 to the outside, the workpiece by the lower motion of the upper mold 14 The first roller 134a and the second roller 134b of the movable portion 130 holding the 10 are along the first taper 116a and the second taper 116b. As a result, the movable part 130 is advanced toward the fixed part 160, and thus the movable material 10 can be easily transferred without using a separate power source.

In addition, since the workpiece 10 is transported by the downward movement of the upper mold 14, the lowering speed of the upper mold 14 and the feed rate of the workpiece 10 are the same, so that the speed required for press working may be satisfied. There is an advantage that can be, because the transfer material 10 to the lower movement of the upper mold 14 has the advantage of reducing the manufacturing cost without using a separate power.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims You will understand.
