The specific embodiment two: the difference of the (see figure 3) present embodiment and the specific embodiment one is, on the holder 13-1 of upper punch 17, increase the lead clamping device is arranged, the lead clamping device by hollow bolt 13-4, steel ball 13-3, hold out against spring 13-5, clamp nut 13-2 forms, hollow bolt 13-4 is threaded with screwed hole 13-6 on the holder 13-1, hollow bolt 13-4 is provided with clamp nut 13-2, steel ball 13-3 and hold out against spring and be located at successively in the hollow bolt 13-4.Other composition is identical with the specific embodiment one with annexation.

The specific embodiment three: the difference of the (see figure 1) present embodiment and the specific embodiment one is that it has increased adjusting screw nut 9 again, and adjusting screw nut 9 is serially connected in the lower end of vertical rod 4.The distance of dashing in order to accurate adjusting low punch 20.Other composition is identical with the specific embodiment one with annexation.

Operation principle; Under the effect of tension spring 15, the protruding 16-1 in the middle of the fork 16 is pressed on the master plate 14 all the time.After equipment started, slide block 13 drove master plates 14 and moves up and down, owing to have waveform groove 14-1 on the master plate 14, made fork 16 around axis swing, thereby made hopper 18 produce vibration and motion, will expect that powder sends in the die 19.The upper punch 17 that is contained on the slide block 13 is being with lead to move downward, and when upper punch 17 during near die 19, stretches out upper punch 17 outer leads and just at first inserts in the material powder.When upper punch 17 continues to press down, just lead is pressed in brush body and has suffered.For the length that lead is imbedded in the brush body reaches requirement, the clamping force that need apply an adjustable size to lead is to overcome the resistance of material powder, and this task is finished by the lead clamping device.When driving, slide block 13 just begins to rise after upper punch 17 presses to minimum point, the cam 1 that ejects that is fixed tightly in this moment on the bent axle 12 just presses down cam follower 4-2 vertical rod 4 is descended, lever 10 rises knock-pin 21 around support 11 motions, and the brush of suppressing is ejected die 19.Simultaneously after upper punch 17 is finished compacting, the unsteady suspension bracket 5 drive scissors 6 that are fixed tightly on the slide block 13 move upward, because of the speed that upper punch 17 rises fast than the speed that knock-pin 21 rises, and the lateral pressure of 19 pairs of brushes of die is greater than the clamping force of steel ball 13-3 to lead, so scissors lead in uphill process is relatively more and more longer, when conductor length reaches specification requirement, the contact of trimming cam 2 depression stroke switches 3, be single automatically controlled two-position-five-way solenoid valve 8 power supplies, commutation, the piston 7-1 of cylinder 7 drives scissors 6 and advances, and cuts off lead.When the contact of trimming cam 2 and travel switch 3 is separated from, travel switch 3 outages, magnetic valve 8 commutations for this reason, scissors 6 returns to initial position, finishes the pressing process of a brush.
