Among the figure: the 1-fuselage; The 2-master cylinder; The 3-distance caging device; The 11-entablature; The 12-slide block; The 13-working slider; The 14-pull bar; The 15-column; The 16-safe grating; The 41-surge-tank; The 42-spill port; A-cap slider position; B-slide block lower position.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the invention protection.
As shown in Figure 1, the structural representation of the hydraulic press that provides for one embodiment of the invention, this hydraulic press specifically can comprise: fuselage 1 and master cylinder 2.
Existing that part-structure is following with the effect division:
Fuselage 1: fuselage 1 is made up of entablature 11, slide block 12, working slider 13, pull bar 14, locking nut and adjusting nut etc.; Rely on four root posts 15 to be support; Entablature 11 and working slider 13 are anchored on two ends by locking nut, and slide block 12 is installed between entablature 11 and the working slider 13.Sliding 12 are connected by locking nut with master cylinder 2 piston rods, rely on four pull bars 14 to do to lead and move up and down, and are furnished with the type groove on the slide block 12, and for example T type groove is used to connect mould, so that the mould installation.
In addition, also be provided with guide rail between working slider 13 and the machinery bed, make things convenient for moving back and forth of working slider.
Master cylinder 2: the cylinder body of master cylinder 2 relies on cylinder mouth shoulder and big locknut to be anchored in 11 centre bores of entablature, and the piston-rod lower end face then links with slide block 12, and the material of piston head is a cast iron; Play the guiding role, the piston head outer surface is equipped with several groups of opposite " Y " type sealing rings, and round section joint ring is housed in the hole; With forming two oil pockets up and down in the cylinder; The cylinder notch portion also is equipped with sealing ring and O shape ring, is locked by cylinder mouth locknut, to guarantee the cavity of resorption sealing.
Simultaneously, on the fuselage 1 safe grating 16 can also be installed, safe grating can be provided with one group or two groups, with tightening security property.
The general course of work is: hydraulic press is (slide block at the upper limit, working slider in rising limit, safety pin rising limit) in position, and safe grating is normal.The operator is placed on workpiece on the working slider, and the both hands push button start sends an initiating signal on the operating desk, and working slider moves inwardly into back limit, and slide block moves down fast; After the slow speed signal induction, add drops at a slow speed, mould is slowly closed up excise the workpiece slitter edge; After slide block lower limit and master cylinder pressure switch motion, after slide block rose to the upper limit, working slider outwards moved to rising limit; The operator touches safe grating near slide unit, takes out of workpiece, and once circulation finishes.
