Title: Pressed product without burrs and its manufacture
Inventor: TATENO TOSHIMASA
IPC: B21D28/16
Filed: 1985-02-27
Abstract: PURPOSE:To improve product quality and to reduce costs by pressing a material from a side and shaving the material from the other side. CONSTITUTION:The material 2 is set between a punch 3 and die 1 and is pressed from the back surface 7 of the material 2 to the front surface 6 in the 1st process. In this time, a somewhat smaller hole than a hole of the finishing size is worked. In the first stage, burrs and a corner rounding 5 are generated on the front surface 6 and the back surface 7, respectively. Pressing for shaving with the finishing size is performed from the front surface 6 of the material 2 to the back surface 7 in the 2nd process. In this time, a punch 3' shears off the burrs on the front surface 6 and a fractured surface 8 and passes through the back surface 7. Thus hand works such as deburring are eliminated and products are finished finely, so that product quality is improved and costs are reduced.
