Abstract
The invention relates to an upper hydraulic cushion structure guided by a guide pillar. The upper hydraulic cushion structure comprises a slider, a hydraulic cushion cylinder, an upper pad and an upper hydraulic cushion. The hydraulic cushion is arranged on the slider, a rod end of the hydraulic cushion cylinder is connected with the upper hydraulic cushion through a stud, the upper pad is arranged at the lower end of the upper hydraulic cushion, the upper pad is combined on the slider through a bolt I, is further matched and connected with the guide pillar by one end of the guide pillar with a thread fastener and is fixed with the guide pillar through a bolt II, the middle of the guide pillar is connected with a positioning sleeve through a matching surface, and the positioning sleeve is combined with the upper hydraulic cushion through a bolt III. The upper hydraulic cushion structure is simple and reliable. Since the upper hydraulic cushion with the pad structure moves vertically along a guide surface, namely a cylindrical surface of the guide pillar, defects of the prior art are overcome, parallelism of the upper hydraulic cushion with the pad structure is guaranteed, and qualified rate of produced parts is increased. In addition, as the guide pillar is fixed with the upper pad via screws exposed on the lower plane of the upper pad, convenience in maintenance is achieved and maintenance cost is reduced.
Description
Technical field
The invention belongs to the hydraulic press technical field, particularly a kind of hydraulic die cushion structure by the guide pillar guiding.
Background technology
During the hydraulic press processing work, upper hydraulic die cushion can affect quality and the precision of product on the depth of parallelism of working face, and this just requires the track of hydraulic die cushion operation and the perpendicularity of working face.As shown in Figure 3 and Figure 4, in structure in the past, upper hydraulic die cushion is hydraulic die cushion on the box-structure, and is highly higher, and the studs II that connects hydraulic die cushion on hydraulic cushion cylinder and the box structure is longer, is unfavorable for tightening; Moving up and down of upper hydraulic die cushion is as spigot surface by guide plate, for ease of dismounting, guide plate is fixed by holding screw and slide block, for guaranteeing the vertical running orbit of hydraulic die cushion, designed jackscrew on the structure, be used for adjusting the depth of parallelism of upper hydraulic die cushion and working face, can produce vibration during owing to the machine operation, cause the position of jackscrew to change.Therefore, just can't guarantee with the depth of parallelism of guide plate as the upper hydraulic die cushion of guiding.The final like this qualification rate that reduces product has increased maintenance cost.
Summary of the invention
The objective of the invention is can improve the product qualification rate for the technical problem that exists in the solution known technology provides a kind of, simple and reliable for structure, the hydraulic die cushion structure of passing through the guide pillar guiding of being convenient to keep in repair.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of upper hydraulic die cushion structure by the guide pillar guiding, comprise slide block, hydraulic cushion cylinder, upper padding plate and upper hydraulic die cushion, described hydraulic cushion cylinder is arranged on the slide block, the rod end of described hydraulic cushion cylinder and upper hydraulic die cushion link together by studs, the lower end of described upper hydraulic die cushion is provided with upper padding plate, described upper padding plate puts together on the slide block by bolt I, described upper padding plate also is threaded an end of button by guide pillar and guide pillar is connected and fix by bolt II, the middle part of described guide pillar is connected by mating surface with positioning sleeve, and described positioning sleeve puts together on upper hydraulic die cushion by bolt III.
Described upper hydraulic die cushion is hydraulic die cushion on the backing structure.
Advantage and good effect that the present invention has are: the present invention is simple and reliable for structure, hydraulic die cushion moves up and down take the face of cylinder of guide pillar as spigot surface on the backing structure, overcome the defective of prior art, guaranteed the depth of parallelism of hydraulic die cushion on the backing structure, improved the qualification rate of product.Because guide pillar and upper padding plate have screw to fix, screw exposes at the upper padding plate lower plane, and convenient maintenance has reduced maintenance cost.
Description of drawings
Fig. 1 is structural front view of the present invention;
Fig. 2 is Fig. 1 top view;
Fig. 3 improves the pre-structure front view;
Fig. 4 improves the pre-structure top view.
Among Fig. 1～Fig. 4,1. slide block, 2. hydraulic cushion cylinder, 3. bolt I, 4. hydraulic die cushion on the backing structure, 5. guide pillar, 6. bolt II, 7. positioning sleeve, 8. bolt III, 9. studs I, 10. upper padding plate, 11. hydraulic die cushion on the box-structure, 12. studs II, 13. guide plates, 14. jackscrews, 15. holding screws.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
As depicted in figs. 1 and 2, a kind of upper hydraulic die cushion structure by the guide pillar guiding, mainly comprise slide block 1, hydraulic cushion cylinder 2, hydraulic die cushion 4 and guide pillar 5 on the backing structure, hydraulic cushion cylinder 2 is installed on the slide block 1, hydraulic die cushion 4 links together by studs I9 on the rod end of hydraulic cushion cylinder 2 and the backing structure, the lower end of hydraulic die cushion 4 is provided with upper padding plate 10 on the backing structure, upper padding plate 10 puts together on the slide block 1 by bolt I3, the end that upper padding plate 10 also is threaded button by guide pillar 5 cooperates with guide pillar 5 to be installed and fixes by bolt II6, the middle part of guide pillar 5 and positioning sleeve 7 are installed together by mating surface, and positioning sleeve 7 puts together on by bolt III8 hydraulic die cushion 4 on backing structure.
Therefore, hydraulic die cushion 4 has overcome the defective of prior art take the face of cylinder of guide pillar 5 as spigot surface moves up and down on the backing structure of the present invention, has guaranteed the depth of parallelism of hydraulic die cushion on the backing structure, has improved the qualification rate of product.Because guide pillar and upper padding plate have screw to fix, screw exposes at the upper padding plate lower plane, and convenient maintenance has reduced maintenance cost.
Although the above is described the preferred embodiments of the present invention by reference to the accompanying drawings; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away from the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
