Abstract
PURPOSE:To prevent the forming of a dead metal zone by equalizing a clearance between a shoe block and grooved bottom surface to the height of feeding blank material in an extrusion grip area, and in other area, by forming a clearance between the blank material and the shoe block. CONSTITUTION:The clearance HS between the shoe block 4 and the bottom surface of groove 1a is set to be Hs Hf in the extrusion grip area l2 and in other area it is set to be Hs>Hf. With the rotation of a grooved wheel 1, the feeding blank material 2 subjected to coining is advanced on a transport passage 3 by a friction force with the groove 1a, the blank material 2 is brought into contact with the groove 1a extensively at a contact part 2a. The blank material 2 in a area l1 of the transport passage 3 is not brought into contact with the block 4 by setting a clearance, so a loss caused by the friction force is eliminated and the extruding pressure is heightened. When the blank material 2 is reached the l2 zone in the passage 3, it is brought into with the block 4 set to Hs Hf and extrusion formed by the sufficiently raised extruding pressure through the die 5.
