Furthermore, the utility model has the advantages of a simple structure and an enhanced service life of the hydraulic press.
Description
Technical field
The utility model belongs to a kind of hydraulic press that is used for Sheet Metal Forming Technology, particularly relates to a kind of hydraulic press that has slide block down fine setting and buffer unit.
Background technology
At present common hydraulic press is when technologies such as punching, blanking, and slide block can lose load suddenly when workpiece is sheared fracture, makes hydraulic press produce huge vibration and noise, thereby the working environment in place is had adverse effect; Slide block loses load suddenly and also can cause elastic potential energy that the oil cylinder inner fluid that drives slide block and fuselage load distortion gathered by instantaneous relase, therefore causes system-wide impact, the service life that can reduce hydraulic press so greatly.In addition, when common hydraulic press is installed bedding-in at mould,, make installation, the bedding-in of mould on hydraulic press very inconvenient because the slide block down amount is big and speed is fast.
Summary of the invention
The utility model provides a kind of mould installation, bedding-in conveniently for solving the technical problem that exists in the known technology, and stamping-out has the hydraulic press of slide block down fine setting and buffer unit stably.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of hydraulic press that has slide block down fine setting and buffer unit, by entablature and sill and about two pillars fuselage, be installed in about fuselage slide block that two intercolumniations move up and down, install the oil cylinder that the driving slide block on the crossbeam moves up and down and the workbench that can horizontal shift-in shifts out that is dragged by hydraulic motor and chain that is installed on the sill is formed, vertical on the lower plane of described slide block both sides two micromatic settings are installed; Two buffer units homoaxial of the vertical installation of corresponding two micromatic settings on the described sill with it.
The utility model can also adopt following technical measures to realize:
Described micromatic setting is to install two nuts that have flange on the lower plane of slide block both sides, the screw rod that has centre bore and keyway is installed in the nut, the top of nut is fixed with stop sleeve, the upper end of stop sleeve is equipped with the motor that has decelerator and the encoder of drive screw turns, the output shaft of decelerator is equipped with key, by its axle and the key screw rod that is slidingly connected.
Described buffer unit is that corresponding two micromatic settings vertically install two cylinder bodies on sill, be equipped with in the cylinder body with the micromatic setting screw coaxial to piston and piston rod thereof, and the oil-in and the oil drain out that are communicated with the piston upper and lower cavity on the cylinder body.
The cylinder body upper port of described buffer unit also is lined with the fairlead of piston rod and the flange of fixed guide cover, and fairlead and flange all are equipped with the sealing ring of piston rod.
Advantage and the good effect that the utlity model has are: owing to install the slide block down micromatic setting additional on the slide block lower plane that moves up and down, on sill, install additional and the corresponding coaxial buffer unit of micromatic setting, not only make slide block that the function of descending fine motion is arranged, and the effect of buffering in addition, mould is installed, bedding-in is more convenient thereby make, the vibration and the noise of stamping-out reduce greatly, have improved the service life of hydraulic press.

The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, fuselage by entablature 1, sill 8 and about two pillars 2 constitute.About two intercolumniations the slide block 3 that moves up and down is installed, be equipped with between upper end of slide block and entablature and drive the oil cylinder 9 that slide block moves up and down, the workbench 7 (dragging) that installing on the sill can horizontal shift-in, shift out by hydraulic motor and chain.In order to make slide block that fine adjustment function be arranged, two micromatic settings 4 are installed at the two ends, the left and right sides of slide block lower plane.Its structure as shown in Figure 2, the vertical nut 47 that has flange 46 of installing on lower plane, install down the screw rod 45 of turn in the nut, nut top is fixed with stop sleeve 48, the sleeve upper end is equipped with motor 41 and decelerator 42, the output shaft of decelerator is that slide key is connected with screw rod, so that the screw rod rotation time also has an axially-movable.For the distance that can show that screw rod moves up and down, an encoder that is connected with display 43 also is installed on decelerator, between encoder and the reducer output shaft by a pair of gear drive.In order to make slide block that a cushioning effect be arranged, two buffer units 6 are vertically installed in the position of opposite ends micromatic setting 4 on sill 8.Its structure as shown in Figure 3, the vertical cylinder body 61 of installing on sill 8, piston 62 and the piston rod 65 thereof that moves up and down is installed in the cylinder body, the good bar of wearability 5 is also installed in the piston rod upper end, also be lined with fairlead 63 between piston rod and cylinder body upper port, the sealing ring of cylinder body and piston rod all is housed on the interior outer cylinder of fairlead, the cylinder body upper surface is equipped with the flange 64 of fixed guide cover by bolt, the sealing ring of piston rod also is housed in the flange center hole, also is provided with the oil-in 67 of connection piston cavity of resorption and the oil drain out 66 of piston upper chamber on the cylinder body.
Operating principle of the present utility model is:
During bedding-in: the piston rod of buffer unit is return upper/lower positions, slide block down, and the screw rod of micromatic setting is with after the damper piston bar contacts, slide block down stops, the rotation of actuating motor drive screw drives the little rising of slide block or little decline, reaches the requirement of mould fine motion bedding-in.
During stamping-out: as shown in Figure 4, come oily P to enter the buffer unit cylinder body, make its piston rod be raised to uppermost position in fig-ure, then slide block down through check valve, when upper mould 10 has just contacted with workpiece 11, adjust the screw rod of micromatic setting and damper piston bar apart from S less than thickness of workpiece L; When workpiece was sheared fracture, cushion dashpot absorbed the potential energy of slide block like this, and at this moment the pressure oil of cushion dashpot cavity of resorption reaches the stamping-out cushioning effect through pressure valve and choke valve oil return.
