The technical scheme that the above-mentioned technical problem of this utility model solution adopts is: the rotation drive machine of a kind of punch press, including reduction box assembly and transmission gear wheel, described reduction box assembly is fixedly mounted in the frame of punch press, described transmission gear wheel is meshed with the output gear in described reduction box assembly, by jointed gear unit transmission between described transmission gear wheel and the sliding drive mechanism of punch press, described frame is fixedly installed independent connecting rod case, described transmission gear wheel and described jointed gear unit are arranged in described connecting rod case.
Described jointed gear unit includes connecting rod and rocking bar, described transmission Large Gear Shaft is connected in described connecting rod case, the medial wall of one end of described connecting rod and described transmission gear wheel is hinged, one end of the other end of described connecting rod and described rocking bar is hinged, the other end of described rocking bar is fixedly installed jackshaft, eccentric setting between described jackshaft and described transmission gear wheel, described jackshaft and described slider-actuated mechanism are connected.
Being fixedly installed eccentric shaft on described connecting rod case to be subject to, described transmission gear wheel and described eccentric shaft are connect by co-axial shafts, and described jackshaft eccentric shaft is connected on described eccentric shaft by upper.
Described slider-actuated mechanism is crankshaft connecting rod system, and described jackshaft is connected by shaft coupling is fixing with the bent axle in described crankshaft connecting rod system.
Be provided with between described connecting rod case and described frame make described jackshaft and described bent axle to the heart to heart guiding mechanism.
Described includes front pods, rear cushion block and lower cushion block to heart guiding mechanism, described front pods or described rear cushion block are taper liner block, described front pods is arranged between front end and the described frame of described connecting rod case, described rear cushion block is arranged between rear end and the described frame of described connecting rod case, and described lower cushion block is arranged between lower surface and the described frame of described connecting rod case.
Compared with prior art, the utility model has the advantages that owing to passing through jointed gear unit transmission between transmission gear wheel and the sliding drive mechanism of punch press, and transmission gear wheel is arranged in the connecting rod case mutually independent with frame with jointed gear unit, both the relatively independent design of jointed gear unit can have been realized, processing and installation, and when needing the ram speed curve of change punch press, have only to jointed gear unit is modified design, other parts of punch press need not be modified design again, it is greatly improved change design efficiency, shorten the manufacturing cycle, be conducive to the series standardized design of punch press, additionally, when after punch press life-time service, owing to jointed gear unit is the most easy to wear, only whole connecting rod case need to be split out the maintenance carrying out part or change during replacing, save maintenance time and cost, and reduce labor intensity.
