Abstract
The invention discloses a small-tabletop link punch. The small-tabletop link punch comprises a rack, a reduction gearbox assembly, a transmission gearwheel, a slide block, and a crankshaft link mechanism for driving the slide block to move up and down, wherein the reduction gearbox assembly is fixedly mounted on the rack; the transmission gearwheel is meshed with an output gear in the reduction gearbox assembly. The small-tabletop link punch is characterized in that the transmission gearwheel is arranged at one side of the rack and is shafted to the rack; the transmission gearwheel is in transmission with a crankshaft in the crankshaft link mechanism through a link transmission mechanism; the link transmission mechanism and the transmission gearwheel are positioned at the same side of the rack; the crankshaft and the transmission gearwheel are eccentrically arranged. The small-tabletop link punch has the advantages that the link transmission mechanism, rather than other parts of the punch, can be simply modified and designed in case that a speed curve of the slide block of the punch is to be modified, so that the modifying and designing efficiency can be greatly improved, and the manufacturing cycle can be reduced; in addition, the whole punch is compact in structure; the left tabletop size and the right tabletop size are small, thus the small tabletop specification applies, and the cost can be reduced.
Description
Technical field
The present invention relates to punch press, particularly relate to a kind of little table top connecting rod 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.Current rotation drive machine is primarily of compositions such as reduction box assembly and transmission gear wheels, sliding drive mechanism has crankshaft connecting rod system, eccentric wheel connecting rod mechanism etc., after transmission gear wheel connects with slider-actuated mechanism, the circular motion of punch press power source is converted to the rectilinear motion up and down of slide block, realizes the punching press of punch press.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, and whole the little table top connecting rod punch press that punching machine structure is compact, table top is less.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of little table top connecting rod punch press, comprise frame, reduction box assembly, transmission gear wheel, slide block and the crankshaft connecting rod system for driving described slide block to move up and down, described reduction box assembly is fixedly mounted in described frame, described transmission gear wheel is meshed with the output gear in described reduction box assembly, described transmission gear wheel is arranged on the side of described frame and is coupling with described frame, by jointed gear unit transmission between bent axle in described transmission gear wheel and described crankshaft connecting rod system, described jointed gear unit and described transmission gear wheel are positioned at the homonymy of described frame, eccentric setting between described bent axle and described transmission gear wheel.
Described jointed gear unit comprises connecting rod and rocking bar, 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, and the other end of described rocking bar is fixedly connected with described bent axle.
Described frame is fixedly installed eccentric shaft near the side of described transmission gear wheel and is subject to, and described transmission gear wheel and described eccentric shaft are coaxially coupling, and described bent axle and described eccentric shaft are coupling by bias.
Described frame is fixedly installed axle by side cover, described eccentric shaft is by being fixedly mounted on described axle by side cover.
Described crankshaft connecting rod system adopts double-crankshaft, and comprise left bent axle and right bent axle, described left bent axle or described right bent axle are fixedly connected with the other end of described rocking bar, are coaxially fixed between described left bent axle and described right bent axle by shaft coupling; Reduce the left and right of press bolster further to size.
Compared with prior art, advantage of the present invention is arranged on the side of frame due to transmission gear wheel and is coupling with frame, and by jointed gear unit transmission between bent axle in transmission gear wheel and crankshaft connecting rod system, 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, and the dismounting of jointed gear unit and easy to maintenance, as long as dismounting axle is by side cover, just can overhaul jointed gear unit and change, in addition, the compact conformation of whole punch press, left and right is less to mesa dimensions, is applicable to little table top specification, also reduces cost.
