Beam, drive rod connects the little slide of hydraulic press by drive pin, and bar of exerting oneself is connected with the slide block of hydraulic press by pin of exerting oneself, elbow
Bar, drive rod and bar of exerting oneself connect further through joint pin, are driven the slide block of hydraulic press by the motion of the oil cylinder of hydraulic press, it is achieved
The reciprocating motion of hydraulic press.
The technical Analysis of the present invention:
The power that in conventional hydraulic machine, oil cylinder applies acts directly on the slide block of hydraulic press, and the oil cylinder applying of hydraulic press
The power that power is subject to equal to the slide block of hydraulic press.Being different from conventional hydraulic machine, this Composite Transmission hydraulic press has a kind of special height
Efficiency symmetry connecting-rod force increasing device.The power that the oil cylinder of this hydraulic press applies is not to act directly on the slide block of hydraulic press, but
By symmetrical connecting-rod force increasing device indirect action on the slide block of hydraulic press.Symmetrical connecting-rod force increasing device is close to lower dead point position
Time there is the reinforcement coefficient of 6-8 times, relatively can reduce exerting oneself of master cylinder with tonnage with speed traditional oils press, make installation hold
Amount reduces.
Advantages of the present invention and beneficial effect:
1) bar-link drive system of hydraulic press is to be driven little slide to move by oil cylinder, drives symmetrical connecting-rod force increasing device, tool
There is the feature that compact conformation, efficiency are high；
2) symmetrical connecting-rod force increasing device has the reinforcement coefficient of 6-8 times when close to lower dead point position, relatively same with tonnage
Speed traditional oils press can reduce exerting oneself of master cylinder, and installed capacity reduces；
3) have employed symmetrical linkage and connecting rod little slide guide pillar, balance radial component, can effectively overcome forcing press
Eccentric load in work, thus keep the high accuracy of slide block.
