Abstract
The invention discloses a rotation transmission mechanism of a punch. The rotation transmission mechanism comprises a reduction gearbox component and a transmission bull gear; the reduction gearbox component is fixedly arranged on the rack of the punch; the transmission bull gear is meshed with an output gear in the reduction gearbox component; the rotation transmission mechanism is characterized in that transmission between the transmission bull gear and a sliding driving mechanism of the punch is realized through a connection rod transmission mechanism; the rack is fixedly provided with an independent connection rod box; the transmission bull gear and the connection rod transmission mechanism are arranged in the connection rod box; the rotation transmission mechanism has the advantages that transmission between the transmission bull gear and the sliding driving mechanism of the punch is realized through the connection rod transmission mechanism, and the transmission bull gear and the connection rod transmission mechanism are both arranged in the connection rod box which is relatively independent from the rack, so that relatively independent design, machining and assembly of the connection rod transmission mechanism can be realized, and when the sliding block velocity curve of the punch needs to be changed, only the connection rod transmission mechanism needs to be changed and designed, while the other parts do not need to be changed and designed; the changing design efficiency is greatly improved; the manufacture cycle is shortened; and serial standardized design of the punch is facilitated.
Description
Technical field
The present invention relates to punch press, particularly relate to a kind of rotation drive machine of punch press.
Background technology
The kind of punch press is a lot, but no matter is which kind of punch press, and its operation principle is all that circular motion is converted to rectilinear motion, primarily of several large parts composition such as motor, flywheel, clutch, rotation drive machine and slider-actuated mechanism.The circular motion of punch press power source, primarily of compositions such as reduction box assembly and transmission gear wheels, is converted to the rectilinear motion up and down of slide block, thus realizes the punching press of punch press by current rotation drive machine after transmission gear wheel connects with slider-actuated mechanism.And every platform punch press after installation is complete, the rate curve of its slide block is changeless, to change the rate curve of this punch press top shoe, then need the rotation drive machine in this punch press and slider-actuated mechanism to pull down and re-start the designs such as size, gearratio, intensity and amendment, even the frame of punch press all needs to coordinate amendment, and its change design efficiency is low, and the manufacturing cycle is long, loaded down with trivial details and the intensity of dismounting is large, series standardized extremely unfavorable to punch press.
Summary of the invention
Technical problem to be solved by this invention is to provide the ram speed curve of a kind of convenience to punch press and changes, and change design efficiency is high, the manufacturing cycle is short, the rotation drive machine of the punch press of easy accessibility.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of rotation drive machine of punch press, comprise 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 independently connecting rod case, described transmission gear wheel and described jointed gear unit are all arranged in described connecting rod case.
Described jointed gear unit comprises connecting rod and rocking bar, described transmission Large Gear Shaft is connected in described connecting rod case, one end of described connecting rod and the madial wall of described transmission gear wheel are hinged, the other end of described connecting rod and one end of described rocking bar are 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.
Described connecting rod case is fixedly installed eccentric shaft be subject to, described transmission gear wheel and described eccentric shaft are coaxially coupling, 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 fixedly connected with by shaft coupling 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 comprises 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, between the front end that described front pods is arranged on described connecting rod case and described frame, between the rear end that described rear cushion block is arranged on described connecting rod case and described frame, between the lower surface that described lower cushion block is arranged on described connecting rod case and described frame.
Compared with prior art, advantage of the present invention be due between transmission gear wheel and the sliding drive mechanism of punch press by jointed gear unit transmission, and transmission gear wheel and jointed gear unit are all arranged on frame phase independently connecting rod case, both the relatively independent design of jointed gear unit can have been realized, processing and installation, and when needing the ram speed curve changing punch press, only need jointed gear unit to be carried out change design, other parts of punch press do not need to carry out change design again, greatly improve change design efficiency, shorten the manufacturing cycle, be conducive to the series standardized design of punch press, in addition, when after punch press Long-Time Service, because jointed gear unit is the most easy to wear, only whole connecting rod case need be split out the maintenance carrying out part during replacing or change, saving maintenance time and cost, and reduce labour intensity.
