Description
Technical field
The present invention relates to a kind of transmission device, particularly driver of press.
Background technology
In existing technology, generally with pressure-sizing, impress, the part adding technological requirement of the complex precise part such as to carve characters, all will produce on multiple stage hydraulic press, hydraulic press efficiency is low, easy oil leakage and the restriction of numerous factor such as the usable floor area taken is large.And production efficiency is higher than hydraulic press on ordinary press, but cold extrusion, impression time upper and lower grinding tool must dieback, but make bent axle easily break like this.
Summary of the invention
In order to solve the deficiencies in the prior art, the object of this invention is to provide a kind of driver of press that can improve the molding time of metal to greatest extent.
To achieve these goals, driver of press provided by the invention, comprise travelling gear, left gear wheel, right gear wheel, left bent axle, right bent axle, connecting rod, upper elbow lever, lower elbow lever, guide pillar, adjusting screw(rod) and slide block, described travelling gear is connected with a joggle with described left gear wheel and described right gear wheel respectively, described left gear wheel is fixedly connected with described left bent axle, described right gear wheel is fixedly connected with described right bent axle, described upper elbow lever is arranged on described left bent axle and described right bent axle by described connecting rod respectively, described upper elbow lever is connected with the lower end of described lower elbow lever, described lower elbow lever by pinned connection on lathe, another hole of described upper elbow lever is connected with described guide pillar, described guide pillar is fixedly connected with described adjusting screw(rod), described adjusting screw(rod) is fixedly connected with described slide block.
Preferably, described left gear wheel is fixedly connected with by key with described left bent axle, and described right gear wheel is fixedly connected with by key with described right bent axle.
Preferably, described guide pillar and described adjusting screw(rod) are threaded connection.
The invention has the advantages that: by the operation curve of multi link elbow-bar mechanism uniqueness, make slide block can stop about 40 ° at bottom dead centre, improve the molding time of metal to greatest extent, advantageously in the plastic deformation of metal.So just can improve the quality of products, save material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein,
1, travelling gear; 2, left gear wheel; 3, right gear wheel; 4, left bent axle; 5, right bent axle; 6, connecting rod; 7, upper elbow lever; 8, lower elbow lever; 9, guide pillar; 10, adjusting screw(rod); 11 slide blocks.
Detailed description of the invention
As shown in Figure 1, driver of press provided by the invention, comprise travelling gear 1, left gear wheel 2, right gear wheel 3, left bent axle 4, right bent axle 5, connecting rod 6, upper elbow lever 7, lower elbow lever 8, guide pillar 9, adjusting screw(rod) 10 and slide block 11, described travelling gear 1 is connected with a joggle with described left gear wheel 2 and described right gear wheel 3 respectively, described left gear wheel 2 is fixedly connected with described left bent axle 4, described right gear wheel 3 is fixedly connected with described right bent axle 5, described upper elbow 7 is arranged on described left bent axle 4 and described right bent axle 5 by described connecting rod 6 respectively, described upper elbow lever 7 is connected with the lower end of described lower elbow lever 8, described lower elbow lever 8 by pinned connection on lathe, another hole of described upper elbow lever 7 is connected with described guide pillar 9, described guide pillar 9 is fixedly connected with described adjusting screw(rod) 10, described adjusting screw(rod) 10 is fixedly connected with described slide block 11.
Preferably, described left gear wheel is fixedly connected with by key with described left bent axle, and described right gear wheel is fixedly connected with by key with described right bent axle.
Preferably, described guide pillar and described adjusting screw(rod) are threaded connection.
Operation principle of the present invention is as follows: rotated by clutch band nutating gear 1 by driven by motor flywheel, drive left gear wheel 2 by engaged transmission gear 1, right gear wheel 3 rotates, left gear wheel 2, right gear wheel 3 connect the left bent axle 4 of drive by key, right bent axle 5 rotates, thus drive the upper elbow lever 7 be arranged on above left bent axle 4, right bent axle 5 to swing, upper elbow lever 7 is by the lower end of bearing pin link lower elbow lever 8, and the other end of lower elbow lever 8 is received on lathe by bearing pin chain; Another hole of upper elbow lever 7 is received on guide pillar 9 by bearing pin chain; The swing of upper elbow lever 7 drives the swing of lower elbow lever 8, upper end due to lower elbow lever 8 is fixing so lower elbow lever 8 is along fixing track swing, the other end of upper elbow lever 7 is linked on guide pillar 9 thus has driven moving up and down of guide pillar 9, guide pillar 9 is by screw thread link adjusting screw(rod) 10, regulate and 10 to be connected by fixed form with slide block 11, thus realize slide block 11 and move up and down.When slide block run to frighten to death some time bent axle continue to rotate and slide block substantially rests on and frightens to death a little, when bent axle continues to rotate, slide block starts backhaul.Thus achieve the function stopping 40 ° at bottom dead centre.
Advantage of the present invention is as follows: by the operation curve of multi link elbow-bar mechanism uniqueness, makes slide block can stop about 40 ° at bottom dead centre, improves the molding time of metal to greatest extent, advantageously in the plastic deformation of metal.So just can improve the quality of products, save material.
More than describe preferred specific embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design concept according to the present invention can make many modifications and variations without the need to creative work.Therefore; all technical staff in the art according to design concept of the present invention on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should within the scope of the present invention and/or by the determined protection domain of claims.
