Abstract
The utility model relates to an electrical control device of buffering opening adjustable height. A worm gear and worm box and a motor are installed on the upper portion of a sliding block, a worm and a worm gear which are matched with each other are arranged in the worm gear and worm box, and the motor is in transmission connection with the worm. An external spline transmission shaft is installed in the middle of the worm gear and is connected with the worm gear, wherein the external spline transmission shaft protrudes downwards, and a ladder-shaped worm is installed at the lower end of the external spline transmission shaft in a sleeved mode. The upper end of the ladder-shaped worm is in transmission connection with the external spline transmission shaft through an internal spline, and the lower end of the ladder-shaped worm is connected with a ladder-shaped nut in a rotating mode and protrudes out of the ladder-shaped nut. The ladder-shaped nut is fixed on the lower end face of the sliding block. An upper buffering cushion block is fixed on the lower end face of the ladder-shaped worm. A buffering cylinder is fixed on a working table, wherein a piston rod is arranged in a cylinder barrel of the buffering cylinder, a lower buffering cushion block is installed at the upper end of the piston rod, and the lower buffering cushion block is opposite to the upper buffering cushion block. The motor rotates through driving of the ladder-shaped worm by the worm, the worm gear and the external spline transmission shaft, and space between the upper buffering cushion block and the lower buffering cushion block can be changed accurately and fast.
Description
Technical field
The utility model relates to a kind of hydraulic press, particularly a kind of motorized adjustment buffering opening adjustment height device.
Background technology
Hydraulic press is when carrying out the operation such as blanking, punching, side cut, because Materials Fracture, resistance of deformation reduces suddenly, often causes sizable impact shock, even causes parts to damage.In the side cut process, descending along with slide block, the side cut punch begins to contact with workpiece, if slide block continues to descend, relative motion (shearing) will occur for workpiece and burr, until Materials Fracture, side cut power sharply rises in short impulse stroke, equals 2/3 place of burr thickness about stroke, and side cut power reaches maximum, then sharply descend again, until be zero.For when the Materials Fracture, the unlikely unexpected mistake of hydraulic press is carried, can slightly surpass thick 2/3 o'clock of material in impulse stroke, in the material bottom or the slide block both sides buffer unit is installed, the resistance that descends to increase slide block carries hydraulic press unlikely unexpected mistake when Materials Fracture, thereby has reduced impact shock.
Owing to need to install different moulds on user's mould structure difference or same hydraulic press, buffer unit buffering opening adjustment height need to be readjusted.The buffering opening adjustment height of existing buffer unit is realized by the turn screw rod, the shortcoming of this device is: need manually-operated, slide block need to be fallen during adjusting, when hydraulic press is higher, inconvenience manually-operated, the adjusting of slide block both sides buffer unit highly are difficult for consistent.
The utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of motorized adjustment buffering opening adjustment height device is provided, and is easy to adjust reliable.
For solving above technical problem, a kind of motorized adjustment buffering opening adjustment height device of the present utility model, comprise the top adjusting device that is fixed on the slide block and be fixed on cushion dashpot on the workbench, be provided with piston rod in the cylinder barrel of described cushion dashpot, described piston rod upper end is provided with lower cushion pad, described slide block top is equipped with worm gear case and motor, be provided with mutually adaptive worm and worm wheel in the described worm gear case, described motor is connected with described worm-drive by synchronous cog belt, described worm gear center is provided with the external splines power transmission shaft that is attached thereto, described external splines power transmission shaft stretches out downwards and the lower end is set with trapezoidal screw, the upper end of described trapezoidal screw is connected with described external splines transmission shaft driven by internal spline, the lower end of described trapezoidal screw is connected with trapezoidal nut and stretches out from trapezoidal nut, described trapezoidal nut is fixed on the lower surface of described slide block, be fixed with cushion pad on the lower surface of described trapezoidal screw, described upper cushion pad is relative with described lower cushion pad.
With respect to prior art, the utility model has been obtained following beneficial effect: the motor-driven worm screw is rotated, the rotation of worm drive worm gear, worm gear drives external splines power transmission shaft rotates, the external splines power transmission shaft drives trapezoidal screw by internal spline and rotates, because trapezoidal nut is fixed on the slide block, the rotation of trapezoidal screw has also just changed the spacing between upper cushion pad and the lower cushion pad so that trapezoidal screw stretches out the length of trapezoidal nut changes to some extent.
Description of drawings
