The specific embodiment
As shown in Figure 3, series connection has the elliptic gear transmission mechanism of speed change transmission performance before slider-crank mechanism, angle can change the press ram kinematic parameter significantly between crank and passive elliptic gear by changing, and can make the forcing press of new design adapt to different pressure processing requirements.
As shown in Figure 3, initiatively the uniform rotation on the elliptic gear 11 is delivered on the passive elliptic gear 12 and has become the speed change rotation, the superimposed kinetic characteristic that just changes press ram of the kinetic characteristic curve of this speed change rotational characteristic curve and crank block, thus its use value enlarged significantly.
As shown in Figure 3, the motor 1 that is installed on the frame 10 provides power, small pulley 2 is housed on the motor 1, small pulley 2 sends power to big belt wheel 4 by driving-belt 3, big belt wheel 4, fulcrum 5 is mutually permanently connected with active elliptic gear 11, drive initiatively elliptic gear 11 by big belt wheel 4, initiatively elliptic gear 11 is meshing with each other with passive elliptic gear 12, passive elliptic gear 12 links to each other with crank 6, and drive crank 6 rotations, crank 6 is connected with connecting rod 8 by connecting pin 7, and connecting rod 8 is connected with slide block 9 by connecting pin 7 ', rotatablely moving of crank 6 is changed into the reciprocating motion of slide block 9 by connecting rod 8.
Passive elliptic gear 12 can be different modes such as spline, screw interconnection system, clutch type with the connected mode of crank 6, with transverse 121 and 6 adjustment that angle α is installed of crank that are used for passive elliptic gear 12, thereby adapt to different pressure processing requirements in plane of rotation.
As shown in Figure 4,6 installation angle α in plane of rotation of the transverse 121 of passive elliptic gear 12 and crank can change.Its adjusting range can be 0～360 degree.
As shown in Figure 5, it has represented passive elliptic gear 12 and crank 6 three kinds of different installation angle α (α=90 degree in plane of rotation, α=180 degree, α=270 degree) kinetic characteristic curve of downforce machine slide block, abscissa is represented the initiatively rotational angle of elliptic gear 11 among the figure, the S curve is represented the relation between press ram 9 displacements and active elliptic gear 11 rotational angles, the stack displacement curve V curve of just representing the kinetic characteristic curve of the variable motion characteristic curve of passive elliptic gear 12 and slide block 9 is represented press ram 9 speed and the relation of elliptic gear 11 rotational angles initiatively, just represents the stack velocity curve of the kinetic characteristic curve of the variable motion characteristic curve of passive elliptic gear 12 and slide block 9.
As seen install after the angle α change, the variable motion characteristic curve of passive elliptic gear 12 is different with the superposed positions of the kinetic characteristic curve of slide block 9, thereby has changed the kinetic characteristic curve of press ram 9.The kinetic characteristic curve of slide block is compared with ordinary press slide block movement characteristic curve shown in Figure 2 tangible change has all been arranged among Fig. 5 A shown in the utility model, Fig. 5 B, Fig. 5 C as can be known from Fig. 5.
As Fig. 4, shown in Figure 5, when the transverse 121 of passive elliptic gear 12 and 6 installation angle α in plane of rotation of crank are 90 degree (referring to Fig. 5 A), this machine slide block 9 has the speed of depressing more uniformly, can satisfy the pressure processing requirement of evenly depressing, and processes as pull and stretch; When if the transverse 121 of passive elliptic gear 12 and 6 installation angle α in plane of rotation of crank are 180 degree (referring to Fig. 5 B), then this machine slide block 9 has the less speed of depressing near bottom dead centre, can satisfy and suppress the pressure processing requirement that pressure increases severely between tailend, process as pressure-sizing; If when the transverse 121 of passive elliptic gear 12 and 6 installation angle α in plane of rotation of crank were 270 degree (referring to Fig. 5 C), then this machine slide block 9 had impulse stroke faster, can satisfy the processing request of quick compactings such as hot pressing.
