Background technology
In the existing press technologies, the transmission balanced structure of general high-speed blanking press adopts the static balancing structure, and concrete structure is exactly the assembling balancing weight opposite with crankshaft eccentric on bent axle, the non-equilibrium state of the main high-speed cruising that causes in order to balance crankshaft off-centre.The advantage of this structure is simple in structure, and cost is low, but can only realize local constitutional balance, can't realize the dynamic equilibrium of complete machine, can't be applied to the high speed and precision punching press.Also there is the dynamic balancing of employing piece to solve the whole machine balancing state in addition, what but the guiding of dynamic balancing piece adopted is four sides plane formula guiding, this structural advantages is the problem that has solved the overall dynamic-balance state, but the structure of planar guide needs regularly to adjust, and adjust inconvenience, maintenance difficult, and when non-equilibrium state occurring, mould has been subjected to grievous injury, reduces the service life of mould greatly.
Summary of the invention
The purpose of this utility model provides and a kind ofly can make that slide block is stable, precision is high, and can improve the dynamic equilibrium mechanism of the high-speed blanking press of whole machine balancing performance.
The technical solution of the utility model is: described high-speed blanking press drives the slide block operation by a pair of ball head connecting rod that is connected on the bent axle, described bent axle is provided with the ball head connecting rod eccentric segment that two-section is used to connect ball head connecting rod, described this two-section ball head connecting rod eccentric segment concentric, between this two-section ball head connecting rod eccentric segment, also be provided with one on the bent axle and be the dynamic balancer eccentric segment of 180 ° of angles with respect to the bent axle axle center, be connected with dynamic balancer on the described dynamic balancer eccentric segment with described ball head connecting rod eccentric segment; Described dynamic balancer comprises dynamic balancing piece, balanced connecting rod, bearing pin and lead; Described balanced connecting rod is movably connected on the dynamic balancer eccentric segment of described bent axle; Described dynamic balancing piece is provided with pin-and-hole, and described dynamic balancing piece utilizes its pin-and-hole to link to each other with balanced connecting rod by bearing pin; Also be provided with pilot hole on the described dynamic balancing piece perpendicular to pin-and-hole; Described lead is fixedly connected on the fuselage, and pilot hole and described lead on the described dynamic balancing piece are slidingly connected.
Bent axle of the present utility model has three off-centre, and two downward eccentric directions are consistent with distance, and concentric is for connecting the off-centre of ball head connecting rod; Another eccentric direction between above-mentioned two off-centre, is the off-centre of connection balance weight in contrast, and distance is determined according to the moment of inertia principle for balance.On the one hand, bent axle is connected by bearing with ball head connecting rod, and ball head connecting rod is realized being connected with slide block by spherical connector, adjusting screw(rod), guide pillar, and slide block is realized the slide block high-speed cruising under the accurate guide effect of two guide pillars and four auxiliary guide pillars.On the other hand, bent axle is connected by bearing with balanced connecting rod, balanced connecting rod is realized being connected with the dynamic balancing piece by bearing, bearing pin, when bent axle rotated, the dynamic balancing piece can move under bent axle drives, and the dynamic balancing piece is under the constraint of lead, only do and move both vertically, the direction of motion is moved into rightabout with slide body, reduces the vibration of fuselage body under the slide block high-speed cruising state greatly, guarantees the precision operation of slide block under high-speed motion state.
