Abstract
The utility model relates to a transmission mechanism of a mechanical press. The transmission mechanism comprises a sliding block, crank shafts and connecting rods. A couple of crank shafts are arranged on the upper end of the sliding block. Connecting rods fixedly connected with the sliding block are arranged on the crank shafts in sleeved mode. The transmission mechanism is characterized in that a big gear A and a big gear B are respectively arrange on the couple of the crank shafts; the big gear A and the big gear B are respectively meshed with a transition gear A and a transition gear B; the transition gear A and the transition gear B are meshed with each other; and the transition gear A is meshed with a small gear driven by a motor. The transition gear A and the transition gear B which are meshed with each other are used for increasing of the distance between the two crank shafts, and the sliding block is ensured to be stable in stress without increasing of the diameters of the big gears, therefore, manufacture cost is not increased on the basis of ensuring a stable and reliable structure.
Description
Technical field
The utility model relates to a kind of punching machine drive mechanism, the punching machine drive mechanism of particularly a kind of Stability Analysis of Structures, reliable and low cost of manufacture.
Background technology
Punching machine is the metal forming machinery with crank connecting link or elbow-bar mechanism, cam mechanism, screw mechanism transmission, is used for material is carried out the lathe of pressure processing, it is deformed and rupture and be processed into part through blank being applied powerful pressure.Stable working, operating accuracy are high, operating condition is good, productivity ratio is high, is easy to realize mechanization, automation, is widely used in industrial machinery forcing presses such as automobile, boats and ships.
The punching machine transmission mechanism mainly comprises train of reduction gears and slider-crank mechanism, and each slider-crank mechanism is called one " point ".The simplest punching machine adopts single-point type, promptly has only a slider-crank mechanism.The punching machine that table top is bigger steadily adopts the two point formula for making the stressed all even motion in slide block bottom surface.In the two point formula punching machine transmission mechanism, the gear wheel on two crank axles directly is meshing with each other, and utilizes intermeshing gear wheel to transmit moment of torsion; The shortcoming of this structure is: when table top is big, and the corresponding increase of slide block size, the strain of gear wheel diameter phase is big; Increased manufacturing cost; If do not increase the gear wheel diameter, the spacing that then need reduce two crank axles adapts to, and slide block is stressed then unstable.
Summary of the invention
The technical problem that the utility model will solve provides the punching machine drive mechanism of a kind of Stability Analysis of Structures, reliable and low cost of manufacture.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of punching machine drive mechanism; Comprise slide block, bent axle, connecting rod, the upper end of said slide block is provided with a pair of bent axle, is set with on the said bent axle to be connected fixing connecting rod with slide block; Its innovative point is: be separately installed with gear wheel A and gear wheel B on said two bent axles; Said gear wheel A, gear wheel B respectively with transition gear A, transition gear B engagement, said transition gear A, transition gear B are meshing with each other, said transition gear A with by motor-driven pinion.
The advantage of the utility model is: utilize intermeshing transition gear A and transition gear B to improve the distance between the bent axle, guarantee the slide block stability under loading, need not to increase the gear wheel diameter, guarantee Stability Analysis of Structures, do not increase manufacturing cost on the basis reliably.

Fig. 1 is the utility model punching machine drive mechanism sketch map.
The specific embodiment
As shown in Figure 1, comprise slide block 1, bent axle 2, connecting rod 3, the upper end of slide block 1 is provided with a pair of bent axle 2, is set with on the bent axle 2 to be connected fixing connecting rod 3 with slide block 1.Be separately installed with gear wheel A4 and gear wheel B5 on two bent axles 2, gear wheel A4, gear wheel B5 respectively with transition gear A6, transition gear B7 engagement, transition gear A6, transition gear B7 are meshing with each other, transition gear A6 with by motor-driven pinion 8 engagements.During work, rotate, drive intermeshing transition gear A6, transition gear B7 rotation, make gear wheel A4 and gear wheel B5 drive bent axle 2 and be connected by motor-driven pinion 8.
