The utility model discloses a servo material-pressing device of a panel veneer numerical control punching machine. The material-pressing device of the panel veneer numerical control punching machine comprises a material-pressing plate, a guiding device and a hydraulic cylinder, wherein a cylinder seat of the hydraulic cylinder is fixed with a rod-punching seat of the panel veneer numerical control punching machine, a piston rod of the hydraulic cylinder is fixed with the material-pressing plate, and the guiding device is a guide sleeve which is compounded in the hydraulic cylinder; the guide sleeve is fixed on a cylinder body of the hydraulic cylinder, the piston rod of the hydraulic cylinder is inserted in the guide sleeve, and the guide sleeve is the guide sleeve of the piston rod of the hydraulic cylinder. According to the material-pressing device of the panel veneer numerical control punching machine, the guiding device is arranged from the exterior of the hydraulic cylinder to the interior of the hydraulic cylinder, the piston rod of the hydraulic cylinder is directly guided by the guide sleeve, and no guide shaft is independently arranged, so the guide shaft is saved, the stability of the movement of the piston rod is improved, then the stability of the movement of the material-pressing plate is improved, and the material-pressing plate is prevented from warping which is caused by unbalance loading. Besides, the guiding device and the hydraulic cylinder are compounded to form a whole, so the material-pressing device is simple in structure, small in size and small in weight.
Description
Technical field
The utility model relates to a kind of sheet-bar puncturing device, particularly a kind of Follow-up material pressing device of numerical control sheet punching machine.
Background technology
Numerical control sheet punching machine for preventing the plate play, has all adopted hydraulic pressure commutation material pressing device when carrying out the punching operation.This device is comprised of mechanisms such as hydraulic system, link, binder parts, and processing and buying parts cycle are long, and installation is complicated, operation is more.Must be by hydraulic system before carrying out the punching operation with the binder parts along Z-direction by compacting on plate, then could begin punching, after plunger chip die lifted, hydraulic means can unclamp.Each punching must be and so forth, and punching speed is low, working (machining) efficiency is slow.This device is also inconvenient in the working service process, and the point that must note is more, in case damage also comparatively inconvenience of maintenance activity, consuming time longer, cause certain economic loss to the user.
The utility model patent that the open applicant of Chinese patent CN201120290203.0 has, it discloses a kind of Follow-up material pressing device of numerical control sheet punching machine, its guider and hydraulic cylinder are split settings, guider is arranged on outside the hydraulic cylinder, can not well lead to hydraulic cylinder piston rod, easily make hydraulic cylinder that holding pad is produced unbalance loading, make the holding pad warpage, in punching course, promote the workpiece skew, affect precision.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of Follow-up material pressing device of integral type numerical control sheet punching machine is provided, makes the piston rod of its hydraulic cylinder as the axis of guide.
For solving the problems of the technologies described above, the utility model comprises holding pad, guider and hydraulic cylinder, the cylinder seat of hydraulic cylinder and the jumper bar seat of numerical control sheet punching machine fix, piston rod and the holding pad of hydraulic cylinder fix, described guider is the fairlead that is compounded in the hydraulic cylinder, fairlead is fixed on the cylinder body of hydraulic cylinder, and the piston rod of hydraulic cylinder is inserted in the fairlead, and fairlead is the fairlead of the piston rod of hydraulic cylinder.
In order to shorten the impulse stroke of holding pad, the piston rod of described hydraulic cylinder is vertical with guide plate.
In order to improve the stability of holding pad motion, described hydraulic cylinder has at least two, respectively is provided with a fairlead in each hydraulic cylinder.
In order to lead more accurately, described cylinder body comprises cylinder barrel and the cylinder cap that is fixed on the cylinder barrel, and fairlead is arranged on the piston rod of cylinder cap and imports and exports the position.
The beneficial effects of the utility model: the utility model outward is set to hydraulic cylinder in by hydraulic cylinder guider, directly the piston rod of hydraulic cylinder is led by fairlead, the axis of guide need not be set separately, save the axis of guide, improve the stability of piston rod movement, thereby improve the stability of holding pad motion, can prevent that holding pad is because of the unbalance loading warpage.And guider and hydraulic cylinder are combined into one, so that the material pressing device structure becomes simply, size is less, quality is lighter.
Description of drawings
Fig. 1 is the main TV structure schematic diagram that the utility model uses state;
Fig. 2 is the A-A profile of Fig. 1;
Among the figure: 1, die change cylinder, 2, the jumper bar seat, 3, hydraulic cylinder, 4, drift, 5, holding pad, 6, die shoe, 7, cylinder barrel, 8, piston rod, 9, fairlead, 10, cylinder cap.
The specific embodiment
A kind of specific embodiment as depicted in figs. 1 and 2, it comprises holding pad 5, guider and hydraulic cylinder 3.This Follow-up material pressing device is installed on the existing perforating press and uses, and perforating press comprises die change cylinder 1, jumper bar seat 2, drift 4 and die shoe 6.Die change cylinder 1 and drift 4 are arranged on the jumper bar seat 2, and die shoe 6 is positioned at the below of drift 4.Holding pad 5 is arranged on the below of the jumper bar seat 2 of perforating press, and guider and hydraulic cylinder 3 all are connected between holding pad 5 and the jumper bar seat 2.
Guider and hydraulic cylinder 3 respectively are provided with two.Guider is fairlead 9, each fairlead 9 is arranged in the hydraulic cylinder 3, and hydraulic cylinder 3 comprises cylinder barrel 7, piston, piston rod 8 and cylinder cap 10, and fairlead 9 is arranged on the piston rod of cylinder cap 10 and imports and exports the position, piston rod 8 is inserted in the fairlead 9, and fairlead 9 is used for piston rod 8 guiding.The overhanging end of piston rod 8 is fixed on the holding pad 5, and piston rod 8 is perpendicular to holding pad 5.
Operation principle: plate is placed on the die shoe 6, and after die change cylinder 1 chose the mould position, perforating press driving jumper bar seat 2 and drift 4 were descending, and holding pad 5 is along with jumper bar seat 2 moves down.Holding pad 5 touches behind the plate and compresses sturdy plate by hydraulic cylinder 3 effects, and drift 4 continues to move downward under the effect of master cylinder and finishes the punching operation.When drift 4 lifts, the piston rod of hydraulic cylinder 3 stretches out, under the effect of fairlead 9, piston rod 8 can keep the fixing direction of motion, and holding pad can not produce unbalance loading, holding pad 5 continues to compress plate under the effect of hydraulic cylinder 3, until after drift 4 broke away from plate fully, the piston rod of hydraulic cylinder 3 was retracted, make holding pad 5 break away from plates, afterwards, thus holding pad 5 just lifts with jumper bar seat 2 and fulfils assignment.
