Description
Technical field
The present invention relates to a kind of forcing press dynamic balance system, particularly a kind of dynamic balance system of heavy-duty press.
Background technology
In crank press drive mechanism, out-of-balance force source mainly contains three aspects: one is the out-of-balance force that slide block pumps, and two is out-of-balance forces that linkage plane motion produces, and three is that eccentric crank rotates the out-of-balance force produced.In high-speed blanking press, if the inertia force produced when each pivoting part and reciprocating part motion can not reach dynamic balancing, the phenomenon that lathe occurs bob and rocks back and forth can be made.In prior art, high velocity ram machine often can only balance the out-of-balance force of above-below direction, and can not balance the out-of-balance force of fore-and-aft direction.Lathe just there will be the phenomenon of rocking before and after lathe when using spring shock-absorbing pad during high-speed motion.
Summary of the invention
The object of the invention is on bent axle, manufacture positive and negative bias, carrying out by installing balanced connecting rod and dynamic balance weight the unbalance inertia force that balance slide block moves up and down; The out-of-balance force in balance crankshaft direction of rotation is carried out additionally by setting-up eccentricity block; Make forcing press complete machine in the vertical direction or all obtain the balance of inertia force in the horizontal direction, thus make lathe be in more stable state.
The technical solution used in the present invention is for this reason: the present invention includes the bent axle (1) being arranged on and fuselage rotates, and described bent axle (1) is provided with positive eccentric shaft (2) and negative bias axle (3) that relative bent axle (1) axis is 180 ° of distributions;
Be arranged with the connecting rod (4) moved with bent axle (1) outside described positive eccentric shaft (2), described connecting rod (4) lower end connection sliding block (5), outside described slide block (5), be provided with the guide rail that slide block (5) is moved both vertically;
Be arranged with the balanced connecting rod (6) moved with bent axle (1) outside described negative bias axle (3), described balanced connecting rod (6) upper end connects balance weight (7), is provided with the guide rail that balance weight (7) is moved both vertically outside described balance weight (7);
Described bent axle (1) is also installed with and the rightabout eccentric block of described positive eccentric shaft (2) (8);
Between described positive eccentric shaft (2) and connecting rod (3), between negative bias axle (3) and balanced connecting rod (6), be provided with axle sleeve.
Described positive eccentric shaft (2) bilateral symmetry is provided with described negative bias axle (3), and what described eccentric block (8) was symmetrical is arranged on described negative bias axle (3) both sides.
Through hole is offered in described connecting rod (3) lower end, is equipped with bearing pin (9) in described through hole, and described slide block (5) is fixed on bearing pin (9).
Described two balanced connecting rods (6) upper end correspondence position is provided with through hole, and be equipped with balance weight bearing pin (10) between two through hole, described balance weight (7) is fixed on balance weight bearing pin (10).
The longitudinal axis of described slide block (1) and balance weight (8) is on same straight line.
Described positive eccentric shaft (2) is in the middle part of bent axle (1).
Advantage of the present invention is: slide block of the present invention and balance weight reach the dynamic equilibrium of above-below direction power by producing the contrary inertia force in direction each other.Eccentric block is then fixedly mounted on direction contrary with positive eccentric direction on bent axle in addition, is used for balance crankshaft bias from the circumferential unbalance inertia force produced when high-speed rotation, has reached the effect of balance lathe fore-and-aft direction out-of-balance force.By above-mentioned two structures simultaneously equalizing pressure machine at unbalance inertia force that is vertical and horizontal direction, make to reach more stable state during machine tool motion with this, the ability being operated in more speed that simultaneously also made lathe possess.

Detailed description of the invention
The present invention includes the bent axle 1 being arranged on and fuselage rotates, described bent axle 1 is provided with positive eccentric shaft 2 and negative bias axle 3 that relative bent axle 1 axis is 180 ° of distributions;
Be arranged with the connecting rod 4 moved with bent axle 2 outside described positive eccentric shaft 2, described connecting rod 4 lower end connection sliding block 5, is provided with the guide rail that slide block 5 is moved both vertically outside described slide block 5;
Be arranged with the balanced connecting rod 6 moved with bent axle 1 outside described negative bias axle 3, described balanced connecting rod 6 upper end connects balance weight 7, is provided with the guide rail that balance weight 7 is moved both vertically outside described balance weight 7;
Described bent axle 1 is also installed with and the rightabout eccentric block 8 of described positive eccentric shaft 2;
Between described positive eccentric shaft 2 and connecting rod 3, between negative bias axle 3 and balanced connecting rod 6, be provided with axle sleeve.
Described positive eccentric shaft 2 bilateral symmetry is provided with described negative bias axle 3, described eccentric block 8 symmetry be arranged on described negative bias axle 3 both sides.
Through hole is offered in described connecting rod 3 lower end, is equipped with bearing pin 9 in described through hole, and described slide block 5 is fixed on bearing pin 9.
