The motor brush manufacturing device that lowers the upper mold that protrudes to and is bite down, heat press molds the motor brush, and lifts the upper mold that loosens the bite of the lead wire to the elevated position is It is known as disclosed in the publication. In this device, the lead wire must be cut below the raised upper mold, but conventionally, mechanical shearing by means of scissors has been adopted. Although this shearing does not cause a problem in cutting the lead wire, it is necessary to fit a flexible insulating coated cylinder such as a synthetic resin cylinder after manufacturing to the lead wire of the manufactured motor brush. However, if mechanical shearing is used, the cut end of the twisted wire does not have cohesiveness, and the twisted wire at the cut end is loosened and broken up. Since it is necessary to fit the insulating coated cylinder after crushing and binding, the work efficiency is extremely poor, and there is a problem that the fitting cannot be automated.

がある製造装置を提供できる。(Operation and effect) The present invention fills a press die of a workbench with brush raw material powder, inserts a lead wire made of a stranded wire, and projects a certain length downward to lower the bite upper die, and press-molds. Then, in the motor brush manufacturing apparatus for raising the upper die with loosened bite of the lead wire, the welding cutter 7 is arranged to advance from the side below the elevated position of the upper die, and the advancement is performed. The stranded wire 6 is sandwiched between the welding electrode pairs 17 and 17 at the end portions, and the lead wire 6 is cut by an electrical action upon energization, and at the same time, the lead wire 6 is electrically burned by a cutting action of fusing at the cut end. Tie it up and make it 4,5
Since the tying wire 6a shown in the figure is generated to prevent the twisted wires from being separated from each other, the flexible insulating tube can be fitted from the cut end without paying attention to the separation of the twisted wires, and It is possible to provide a manufacturing apparatus that has the action and effect peculiar to a lead wire made of a stranded wire.
