Abstract
The utility model relates to a servo-press transmission system, which comprises a servo motor, a speed-reducing mechanism, a crankshaft, a toggle-rod mechanism, a driving rod, a model-regulating screw and a slide block, wherein the model-regulating screw is in a flat-bottom structure, a convex shoulder is arranged at the middle part of the model-regulating screw, and the external threads of the model-regulating screw are connected with the internal threads of the driving rod: when the model-regulating screw downwards moves under the action of the driving rod, a stamping force is transferred to a screw seat through the bottom plane of the model-regulating screw to further drive the slide block to realize downward stamping operation; and when the model-regulating screw upwards moves, the returning movement of the slide block is realized through the upper ring surface of the convex shoulder of the model-regulating screw and a pressure cover which is fixedly connected to the slide block. The servo-press transmission system has the characteristics that: the mechanical structure of the slide block is greatly simplified, the processing property is good, and the manufacturing precision is easy to ensure; a lateral force generated by the transmission system is born by a driving-rod guiding mechanism, the lateral force acted on a slide-block guide rail is greatly decreased, the slide block is steady in operation, the abrasion of the guide rail is lightened, and the service life of a machine tool is prolonged.
Description
Technical field
The utility model relates to a kind of servo-pressing machine transmission system, the particularly transmission system of toggle rod type servo-pressing machine.
Background technology
Exist pressure curve to ordinary press and fix, degree of flexibility is relatively poor, has released multi-form servo-pressing machine in recent years one after another, has not only improved the machining accuracy and the operating efficiency of forcing press, has also improved the Sheet Metal Forming Technology scope of forcing press greatly.But, unavoidably also come with some shortcomings in performance and structure aspects because servo-pressing machine time that emerges is shorter.Like 200820082737.2 patented technologies " Numerical control servo pressure machine drive mechanism " by State Intellectual Property Office's bulletin; Use force booster type elbow-bar mechanism driving pressure machine slide block and carry out stamping press; Improve the degree of flexibility of forcing press, saved the servomotor power demand.Yet this technology is still being continued to use the ball screw structure of ordinary press slide block, and its anufacturability is poor, cooperates with ball cup and bulb gland to require height; In addition should technology effect has larger side pressure to bed ways, cause way rub fast, influence forcing press service life.
The utility model content
The utility model provides a kind of servo-pressing machine transmission system of designs simplification to the deficiency that prior art exists.
The technical scheme of the utility model is: the utility model comprises servomotor, reducing gear, bent axle, elbow-bar mechanism, drive rod, mode transfer screw rod, slide block and mould adjusting mechanism composition.Reducing gear includes a pair of synchronous pulley and a pair of gear constitutes the double reduction motion.Elbow-bar mechanism comprises toggle link, upper pendulum bar and draft link.The mode transfer screw rod is a flat-bottom structure, and mode transfer screw rod bottom is provided with the screw bolt seat that engages with mode transfer screw rod baseplane, and screw bolt seat connects slide block through the overload protection oil cylinder; The screw rod middle part is provided with a convex shoulder, engages the gland that is fixed on slide block with the convex shoulder upper ring surface.
Said drive rod arranged outside one is fixed in the fairlead on the fuselage body.
Said drive rod and mode transfer screw rod are of coupled connections through internal and external screw thread.
Said mould adjusting mechanism is made up of mode transfer motor, worm couple, transmission flat key, mode transfer screw rod, and the mode transfer motor directly is connected with worm couple, connects through the transmission flat key between worm couple and the mode transfer screw rod.
The characteristics of the utility model are: the utility model has been done relevant improvement to the frame for movement of mode transfer screw rod, and slide block structure is simplified greatly, and its good manufacturability, the accuracy of manufacture are easy to guarantee; The side force that transmission system produced is born by the drive rod guiding mechanism, and the side force that acts on the slide block guide rail reduces greatly, reduces way rub, and slide block operates steadily, and improves lathe service life.
