Clockwise stops curve after turning to the depanning of ba edge sections, as shown in fig. 7, when stopping curve after ba edge sections and depanning,
Because the radian of ba edge sections is identical, therefore L-shaped knee-piece 13 keeps same transition inconvenience, therefore the gear unit also keeps former
The motion state come is constant, to modulus, makes modulus safer.When cam 11 continues to rotate to the i.e. backhaul curves of ad, institute
L-shaped knee-piece 13 is stated to rotate counterclockwise, under the effect of powder product product trimmer body interior strength, the rolling in its first end 131
Wheel 18 is close to the first end 131 towards close to the lateral movement of bent axle 12 1, drives the power transmission shaft 14 to lower swing, the biography
Moving axis 14 by the spacing collar 15 make the main shaft 16 move downward be eventually returned to dc edge sections i.e. lower dead center curve so as to
Resetted, return to state as shown in Figure 5, complete time processing process.When cam ejecting mechanism 1 moves upwards, it drives
The punching once 5 and two times punchings 6 are moved, and the product in former 4 is ejected, is finally completed the demoulding.
In the present invention, it is combined using crankshaft cam with L-shaped knee-piece 13, makes the motion of the cam ejecting mechanism 1 more
It is stable, while the reset of prior art cam ejecting mechanism 1 needs a kind of external force effect of cylinder, and bent axle is only needed in the present invention
12 rotations can realize reset, while set roller 18 to reduce the cam 1 and institute in the first end 131 of the L-shaped knee-piece 13
State the friction between L-shaped knee-piece 13.
Presently preferred embodiments of the present invention is the foregoing is only, is merely illustrative for the purpose of the present invention, and it is non-limiting
's.Those skilled in the art understands, many changes can be carried out to it in the spirit and scope that the claims in the present invention are limited,
Modification, in addition it is equivalent, but fall within protection scope of the present invention.
