Description
Technical field
The present invention relates to a kind of punch press, be specifically related to a kind of accurate lever punch bed.
Background technology
The design principle of punch press is that circular motion is converted to rectilinear motion, exerted oneself by mair motor, flywheel driven, through runnings such as clutch band moving gear, bent axle (or eccentric gear), connecting rods, reach the rectilinear motion of slide block, complete press work, but directly adopt bent axle or eccentric gear to drive the mode of slide block movement to need larger driving force just can reach punching press object, expend electricity many.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of structure, saves the accurate lever punch bed of electric energy.
The technical solution used in the present invention is: a kind of accurate lever punch bed, the rocking arm that it comprises frame, the power transmission shaft be arranged in frame, the eccentric block be arranged on power transmission shaft, the drive link be socketed with eccentric block, one end are hinged with drive link, the kinematic link, the slide block be connected with kinematic link and the drive unit be connected with power transmission shaft that are hinged with the rocking arm other end; The middle part of described rocking arm is connected by rocker arm shaft with frame.
Described rocker arm shaft is arranged near kinematic link side.
Described drive unit comprises driving shaft, setting driven wheel on the driving shaft, setting belt pulley, the motor be connected with belt pulley and the travelling gear be arranged on power transmission shaft on the driving shaft; Described power transmission shaft is provided with travelling gear, and described driven wheel is meshed with travelling gear.
Described drive link is connected one end with rocking arm and is provided with Baltimore groove, and described rocking arm is arranged in Baltimore groove, passes through pinned connection with Baltimore groove.
Described drive link is connected one end with power transmission shaft and is provided with axle sleeve, and described drive link is connected with power transmission shaft by axle sleeve; Described axle sleeve and eccentric block shape suitable.
Good effect of the present invention is: the mode adopting eccentric block to be combined with rocking arm drives slide block, and structure is simple, little to power demand under same impulsive force, saves electric energy; The rocker arm shaft of rocking arm, near kinematic link side, forms lever, can obtain larger outputting power, save power consumption further under less input power effect; Drive unit adopts stage-geared, and output to eccentric block from drive motors and export, driving force increases gradually, realizes less input power and reaches larger outputting power; Drive link is connected with rocking arm by Baltimore groove, and scope of activities is large, easy for installation; Drive link is connected by axle sleeve with eccentric block, easy for installation, is convenient to maintenance; Belt pulley, gear do not expose, and reduce industrial accident noise little, simple good maintenance.
