Description
Technical field
The utility model belongs to hydraulic press technical field, particularly a kind of hydraulic press step-up system.
Background technology
Hydraulic press is primarily of critical piece compositions such as entablature, sill, guide pillar, slide block, oil cylinder, frame, moulds, and by hydraulic oil piston rod in oil cylinder, piston rod promotes reciprocating with the slide block of mould, completes the action of pressing component.
Existing piston rod connection sliding block is mainly rigidly connected, hydraulic stem Direct driver slide block mechanism, and the cylinder diameter of charge oil pressure and oil cylinder determines the size of honest pressure, there is the problems such as power consumption is large, complete machine speed is low, and reinforcement is not enough.
Want the existing honest pressure of increase of several times, or increase charge oil pressure, or be exactly the cylinder diameter of increase oil cylinder, the also increase at double of corresponding cost; But power and speed are inversely proportional to, certainly will speed be sacrificed, affect productive temp, finally affect the production marketing of enterprise.Current existing market major part drives to solve by multi-cylinder and increases hypodynamic situation, but production efficiency is not high, this is also the difficult problem always perplexing enterprise, market has in medium-small hydraulic press to have and relates to simple two connecting-rod force increasing devices, but reinforcement is not obvious, design angle change is also little, and productive temp is not high yet.
Summary of the invention
The utility model provides a kind of hydraulic press step-up system for solving in known technology the technical problem that exists, solve the above hydraulic press of kiloton fast and ensure enough honest pressure, the increase at double of honest pressure is made under the prerequisite not changing charge oil pressure and cylinder diameter, and can also productive temp be ensured, optimize structure, thus change the situation that traditional charge oil pressure and oil cylinder cylinder diameter determine productive temp and honest pressure, for enterprise saves a large amount of funds, be more or less the same by the testing result of reality and theory, realize 4 to 5 seconds strokes the soonest.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of hydraulic press step-up system, comprise symmetrically arranged four drive pins be installed on mobile device, each drive pin connects a drive rod, each drive rod is connected with toggle link and bar of exerting oneself by joint pin, the other end of described bar of exerting oneself is hinged with the moving slider of band mould by pin of exerting oneself, and the other end of described toggle link is hinged by the slide on knuckle-pin and entablature.
Described pin of exerting oneself, joint pin, knuckle-pin and drive pin are provided with copper bush respectively and between the rod aperture be connected.
The advantage that the utility model has and good effect are: the utility model mechanism analyzes the link motion position to the radians such as eight, the motion of drive link, toggle link, bar of exerting oneself is divided into two parts, negative 70 ° within the scope of this are rotated clockwise at horizontal level by analyzing toggle link, the speed of this process is just in time one and first increases the process reduced again, finally realize the quick movement of slide block, improve productive temp; In the end the rapid lift-rising of honest pressure of the scope inner mold in several years is big to 4,5 times, completes pressing component.The change curve of honest pressure in whole motion process is as Fig. 4, show more outstanding in the hydraulic press that tonnage is larger is suppressed fast, especially be a no small technological break-through for hydraulic press more than kiloton, play good economic effect, for enterprise brings huge benefit.
