On bearing, another power transmission shaft opposite side fixed chain wheels fourth, sprocket wheel fourth passes through the passive transmission mechanism of chain and support opposite side
Sprocket wheel fourth connects；
The connecting shaft bottom sets spur gear, and spur gear engages with another spur gear, and another spur gear is fixed on adjustment
On axle sleeve, adjustment axle sleeve is vertically rotatably connected on bearing, and adjustment axle forms screw pair with adjustment screw mandrel, adjusts on screw mandrel
Side is compacting oil cylinder；
Motor, in the mounting seat of the main drive gear of machine frame inside side, motor output shaft by shaft coupling with
Connect axis connection.
Preferably, guiding mechanism is set between the adjustment screw mandrel and guide support seat, makes the movement of adjustment screw mandrel more steady.
More specifically, the guiding mechanism is provided with guide groove for the upper end of adjustment screw mandrel, and with leading on guide support seat
It is engaged to key.
Preferably, another power transmission shaft other end is more stable by support base rolling support, so another drive axis.
Compared with prior art, the utility model has the advantage of：Because adjustment mechanism motor is connected directly between side tooth
It is driven on the gear shaft of wheel, transmission is more steady, and power transmission loss is smaller, and motor is placed on machine frame inside, can completely cut off outer
The influence of magnetic material material and combustible to motor in portion's environment dust, improve electrical machinery life and security.

Embodiment
The utility model is further described below in conjunction with accompanying drawing embodiment.
As shown in figure 1, powder metallurgy forcing press former active floating regulating mechanism, including：Mutually isostructural active accommodation
Mechanism and passive adjustment mechanism, motor.
The active accommodation mechanism and passive adjustment mechanism are symmetrically mounted on the both sides inside frame 1.
The active accommodation mechanism includes mounting seat 2, support base 3, bearing 4, power transmission shaft 5, power transmission shaft 6, bevel gear 7, umbrella
Gear 8, connecting shaft 9, spur gear 10, spur gear 11, adjustment axle sleeve 12, adjustment screw mandrel 13, guide support seat 14, sprocket wheel 15, chain
Wheel 16 and sprocket wheel 17.
The mounting seat 2 is fixed on the inside of frame 1.
The upper end of connecting shaft 9 is installed by bevel gear 8, lower end installation spur gear 10.
The power transmission shaft 5 is provided with sprocket wheel 15, the end of power transmission shaft 5 by support base 3 and the rolling support of mounting seat 2, power transmission shaft 5
Provided with the bevel gear 7 being meshed with bevel gear 8.
The support base 3 is fixed on support 1.
Adjustment axle sleeve 12 lower end is provided with the spur gear 11 being meshed with spur gear 10, and passes through the through hole of mounting seat 2,
Upper end is threadedly coupled with adjustment screw mandrel 13 lower end.
The adjustment screw mandrel 13 is fixed in mounting seat 2 by the vertical support of guide support seat 14, guide support seat 14.
The power transmission shaft 6 is by the rolling support of bearing 4, and its both ends is respectively equipped with sprocket wheel 16 and 17, and sprocket wheel 16 passes through chain 19
It is connected with the sprocket wheel 15 on top, sprocket wheel 17 is connected by chain with the respective sprocket 17 of passive adjustment mechanism.
The motor 18 is arranged in the mounting seat 2 of the side of frame 1, the output shaft of motor 18 by shaft coupling (in figure not
Show) it is connected with connecting shaft 9.
As shown in figure 3, the upper end of the adjustment screw mandrel 13 is provided with the feather key on guide groove 1301, with guide support seat 14
1401 are engaged, and can so ensure that adjusting screw mandrel 13 moves up and down steadily.
The adjustment process of powder metallurgy forcing press former active floating regulating mechanism is as follows：
The adjustment of the upper-lower position of screw mandrel 13 is first adjusted, its process is：Motor 18 drives connecting shaft 9 and installed thereon
Spur gear 10 rotate together so that the spur gear 11 that is meshed with spur gear 10 drives adjustment axle sleeve 12 to rotate, due to adjusting
Whole screw mandrel 13 is to be threadedly coupled with adjustment axle sleeve 12, so the rotating of adjustment axle sleeve 12 can just make to move down on adjustment screw mandrel 13
It is dynamic；At the same time, the bevel gear 7 engaged is driven to rotate by the rotation of the bevel gear 8 in connecting shaft 9, and then
Rotated by power transmission shaft 5 with movable sprocket 15, then the chain of the passive adjustment mechanism for the opposite side of driving frame 1 for passing through sprocket wheel 16 and 17
Wheel 17 and 16, so as to drive the sprocket wheel 15 of the opposite side of frame 1 to rotate, the opposite side of frame 1 is realized by such transmission mechanism
Adjustment screw mandrel 13 synchronously moves up and down.
By adjusting the upper-lower position of adjustment screw mandrel 13, make piston-rod lower end face and the adjustment screw mandrel of pressing pressure oil cylinder 20
The distance between 13 upper surfaces L is changed.Pressing pressure oil cylinder 20 is downward, lower surface and the adjustment screw mandrel 13 of its piston rod
Upper surface contact, drive adjustment screw mandrel 13 and adjustment axle sleeve 12 move downwardly together, by adjusting adding for the bottom of axle sleeve 12 connection
Pressure pad block 21 promotes transverse arm 22 also downwards, to see Fig. 3, the former being so connected with transverse arm 22（Do not show in figure）Also decline therewith, it is real
The active of existing former is floated.
As shown in Figure 1 and Figure 2, because the stroke of pressing pressure oil cylinder 20 is constant, L apart from smaller, get over by the distance that former declines
Greatly, i.e., former active amount of floating is big；L distances are bigger, and the distance that former declines is smaller, i.e., former active amount of floating is small.So this
The former active floating regulating mechanism of utility model can carry out former active amount of floating according to the actual requirement that need to produce product
Accommodation.
