Description
Technical field
The utility model relates to pressure processing technology field, more particularly, relates to a kind of gradually pressurization and the link lever press with force amplification effect.
Background technology
In pressure processing field, in the time that pressure is little, be generally to adopt punching machine to meet production requirement, in the time that needs pressure ratio is larger, conventionally being difficult to provide desired power by motor-driven punching machine, is generally at this moment to replace punching machine with hydraulic press.Forcing press claims again: hydraulic press, hydraulic press.Common other hydraulic press of ton is all the setting that adopts hydraulic cylinder arranged side by side now, between upper plate and lower plate, portable plate is set, some hydraulic cylinders are set between portable plate and upper plate, by contraction and the stretching, extension of hydraulic cylinder, portable plate obtains the strength pressing down, such pressure transmission effect is straight line, and in the situation that not considering frictional dissipation, the downforce of portable plate is the tension force of hydraulic cylinder.
In the time that single hydraulic cylinder reaches its maximum load, if need larger output pressure, be generally diameter by increasing oil cylinder or with multiple hydraulic cylinders and fetch realization.The method that increases cylinder diameter can cause the problem of a lot of other sides, for example the control problem of large flow, the poor electrohydraulic servo system of large stream; Multiple hydraulic cylinders the method connecing need to be controlled multiple oil cylinder synchronous coordination motions, and frame for movement can be more complicated, and required energy consumption also can increase, and maintenance and inspection expense is higher, and this is also the problem of a bad solution.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant is through repeatedly putting into practice improvement, design the link lever press that gradually pressurizes, solved and thought that intensified pressure acc power can only longitudinally increase the problem of hydraulic cylinder quantity or power, obtained larger pressure result with less afterburning cost.
Technical scheme: in order to realize foregoing invention object, the technical scheme that the utility model adopts is: link lever press gradually pressurizes, its structure comprises: working plate, upper plate and moving plate, on described working plate, be symmetrical set the upper end that two guide pillars, described upper plate are fixed on two guide pillars, described moving plate is socketed on two guide pillars by guide pin bushing, and described moving plate is free rise/fall on two guide pillars.Pressure connecting rod and downforce connecting rod are set between described upper plate and moving plate, and described upper pressure connecting rod and downforce connecting rod are fixed on the outer surface of intermediate bushing, between the intermediate bushing of two of left and right, force-boosting driving device are set.
Further, for pivot pin in obtaining is with upper pressure connecting rod and the outwards effect of motion of downforce connecting rod, the further technical scheme of the utility model is: the power transmission portion of described force-boosting driving device is connected with the middle pivot pin that is arranged on intermediate bushing center.
Can have multiple choices scheme about above-mentioned force-boosting driving device, as long as certain flexible tension force can be provided, can be even by the outwards pulling force of action of two middle pivot pins.Consider assembly cost and operating space, the utility model provides a kind of preferred technical scheme, adopt telescoping hydraulic cylinder, be specifically expressed as follows: described force-boosting driving device is telescoping hydraulic cylinder, described telescoping hydraulic cylinder is connected with middle pivot pin by pressure cylinder connecting component.
Again further, being connected by the cooperation of axle bed, pivot pin and bearing shell between described upper pressure connecting rod and upper plate completes, the upper end of described upper pressure connecting rod is fixedly connected on the outer surface of bearing shell, and pivot pin is fixed on axle bed, and described axle bed is fixed on the lower surface of upper plate by shear pad.So just can ensure upper pressure connecting rod connect one end of intermediate bushing pushed outwards go out or inwardly shrink in, the other end can rely on the cooperation of bearing shell and pivot pin, makes corresponding action of rotating to the left or to the right.
Finally, described guide pillar is fixedly connected with upper plate by guide pillar nut.
When real work, workpiece to be processed is placed on working plate, under moving plate, the utility model mainly relies on force amplificatory structure to realize the increase of power.Specifically be expressed as: in the process of shrinking at telescoping hydraulic cylinder stroke, telescoping hydraulic cylinder has chamber bar to work, at this moment telescoping hydraulic cylinder provides pulling force, telescoping hydraulic cylinder passes to middle pivot pin by pressure cylinder connecting component power, pass through intermediate bushing, make the angle between pressure connecting rod or downforce connecting rod and guide pillar more and more less, because upper plate has been fixed on guide pillar by guide pillar nut, the effect realizing is exactly that moving plate declines, in the process declining at moving plate, due to the counter-force of load, the pressure on workpiece also can be increasing by mould action for moving plate, realize the gradually action effect of pressurization,
In the process of amplifying at telescoping hydraulic cylinder stroke, the rodless cavity of telescoping hydraulic cylinder works, and makes moving plate increase.In sum, the utility model is realized the object of pressure control and Stroke Control by hydraulic pressure and control system.
Pressure conversion formula is as follows:
F=F
telescoping hydraulic cylinder× cot θ
Wherein, F is the power pressing down that plate obtains, and F telescoping hydraulic cylinder amplifies the power providing for telescoping hydraulic cylinder stroke, and θ is that upper pressure connecting rod or downforce connecting rod are the angle between guide pillar.By this formula, we can be clear that telescoping hydraulic cylinder stroke amplifies the power providing by this mechanism, has obtained amplification.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
1, the utility model adopts the structure that upper pressure connecting rod and downforce connecting rod coordinate, and manufacturing structure is simple and reliable, and manufacturing cost is lower.By the force-increasing mechanism of connecting rod, make that the only driving with a telescoping hydraulic cylinder just produces multiple equal oil cylinders and connect just available power output, reduce cost, do not have the control difficult problem that multiple oil cylinders need synchronous coordination motion yet.
2, the utility model adopts fairly simple structure can obtain larger downforce, and assembly space is all less than traditional hydraulic press or hydraulic press, overhauls also more convenient.
