Description
Technical field
The utility model relates to Machining Technology field, more particularly, relates to a kind of 90 ° of power to changing jointed gear unit.
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.
Our company is through practice, having changed multiple hydraulic cylinders vertically has an effect and obtains the structure of pressure or power, the bar linkage structure that adopts a kind of direction vertical direction of and required power to have an effect, the amplification that not only can utilize link transmission to acquire strength, and in actual use, coordinate control system by the travel parameters of adjusting single oil hydraulic cylinder, just can realize pressure controlled object, structure is simpler, and it is also more convenient to operate.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant is through repeatedly putting into practice improvement, a kind of 90 ° of power are designed to changing jointed gear unit, solve and thought that intensified pressure acc power can only longitudinally increase the problem of hydraulic cylinder quantity or power, and under different user demands, pressure, lift be can obtain, pressure and lift even can be obtained simultaneously.
Technical scheme: in order to realize foregoing invention object, the technical scheme that the utility model adopts is: a kind of 90 ° of power are to changing jointed gear unit, comprise upper die and lower die, two ends, described patrix left and right arrange axle bed, in described upper axle bed, pivot pin and top bearing shell are set; Two ends, described counterdie left and right arrange lower axle bed, in described lower axle bed, lower shaft pin and lower bearing are set.
Bindiny mechanism between described upper die and lower die is specifically expressed as: upper driving connecting rod and underdrive connecting rod are set between described patrix and counterdie, described upper driving connecting rod is connected with intermediate bushing with underdrive connecting rod, described intermediate bushing inside is provided with middle pivot pin, and shaft-like retractable driving device is set between pivot pin in both sides.
Shaft-like retractable driving device is set between pivot pin in described both sides multiple choices, as long as can meet the tension force and the contracting power that provide certain, this practicality provides a kind of implementation, and described shaft-like retractable driving device adopts oil hydraulic cylinder.
Further, described upper driving connecting rod is identical with the shape and structure of underdrive connecting rod.
Again further, described upper pivot pin is fixed on axle bed, and top bearing shell freely rotates on upper pivot pin; Described lower shaft pin is fixed on lower axle bed, and lower bearing freely rotates on lower shaft pin.
Further, described patrix/counterdie is fixed die, and correspondingly counterdie/patrix is movable mold.When patrix is fixed die, when counterdie is movable mold, when oil hydraulic cylinder stroke amplifies, counterdie provides downforce; When counterdie is fixed die, when patrix is movable mold, when oil hydraulic cylinder stroke dwindles, patrix provides climbing power.
When described shaft-like retractable driving device is oil hydraulic cylinder, during for fixture, described upper die and lower die are movable mold, and at this moment, in the time that oil hydraulic cylinder stroke amplifies, described patrix provides climbing power, and counterdie provides downforce simultaneously.
In sum, the utility model obtains power by oil hydraulic cylinder stroke alteration, arranges by kinematic link, realizes 90 ° of power to the object that changes link transmission.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
1, the utility model adopts the structure that upper driving connecting rod and underdrive connecting rod coordinate, and manufacturing structure is simple and reliable, and manufacturing cost is lower.By the force-increasing mechanism of kinematic link, make that the only driving with an oil hydraulic cylinder just produces multiple equal oil cylinders and connect just available power output, reduce cost.
2, the utility model is that fixed die or counterdie are fixed die by patrix is set, and can obtain downforce or climbing power, and when oil hydraulic cylinder is made as to fixture, can obtain downforce and climbing power simultaneously, and the scope of application is more flexible.
Brief description of the drawings
Fig. 1 is that a kind of 90 ° of power of the utility model are to the structural representation that changes jointed gear unit.
Detailed description of the invention
Below by a most preferred embodiment, the technical program is elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of 90 ° of power, to changing jointed gear unit, comprise patrix 1, counterdie 2, and described patrix 1 two ends, left and right arrange axle bed 3, interior pivot pin 5 and the top bearing shell 7 of arranging of described upper axle bed 3.Described counterdie 2 two ends, left and right arrange lower axle bed 4, interior lower shaft pin 11 and the lower bearing (12) of arranging of described lower axle bed 4.Upper driving connecting rod 7 and underdrive connecting rod 10 are set between described patrix 1 and counterdie 2, described upper driving connecting rod 7 is connected with intermediate bushing 9 with underdrive connecting rod 10, upper driving connecting rod 7 is identical with the shape and structure of underdrive connecting rod 10, described intermediate bushing 9 inside are provided with middle pivot pin 8, and shaft-like retractable driving device 13 is set between pivot pin 8 in both sides.
