PURPOSE:To easily enable a thick wire used to be cut down by providing a mechanism where the wire is bent at a bonding point in cutting the wire. CONSTITUTION:A wire clamper rocking lever 41 is turned round by a given angle counterclockwise by means of a cam 40 for bending the wire, whereby a long groove 41a formed in the lever 41 is engaged with a pin 45 to turn round a wire clamper 20 clockwise and the wire is bent at the base of a tool. In this condition, the first wire cutting lever 25 is turned round counterclockwise by a cam 24 for wire cutting down and the second wire cutting lever 29 is turned round clockwise. By this, the wire clamper 20 is alienated from the tool 11 with the wire 4 remaining held thereby and as a result, the wire 4 is cut down at the bonding unit. Thus, the wire is bent and cut down at the root of the tool 11, so that even a thick wire can easily be cut down. |
