Abstract
The invention discloses a protector of a pressure machine, which is provided with a hydraulic cylinder, wherein the middle part of the hydraulic cylinder is fixed with a pressure head through a positioning and guide flange and a bolt, an oil storage chamber is arranged in the pressure head, a safety valve is arranged at the bottom part of the pressure head, the safety valve is communicated with the oil storage chamber, a sealing ring is arranged between the pressure head and the hydraulic cylinder, hydraulic oil is closed between the pressure head and the inner hole of the hydraulic cylinder, and the size of the hydraulic oil after being compressed is less than or equal to the volume of the oil storage chamber at the upper part of the pressure head. When the working pressure of the pressure machine acts on the pressure head, and is over the pressure born by the safety valve, the safety valve is open, the pressure head moves downwards, the hydraulic oil is discharged into the oil storage chamber through the safety valve, and thus, the purpose of the safety protection is achieved.
Description
Technical field
The present invention relates to a kind of press technology, specifically is a kind of protector of forcing press.
Background technology
At present, the protector of forcing press has two kinds of versions, and a kind of is so-called rigidity protector; in fact this kind protector serves as the function of cutout at work; under the situation of pressure overload,, and protect the safety of other important parts and whole forcing press by self damaging of protector; so; the rigidity protector has advantage of simple structure, still, because it act as disposable; so; in case after damaging, must re-design, still; user as forcing press; design and fabrication must be according to the knowledge of specialty, the relevant parameter of forcing press, and need necessary equipment; so this just brings many troubles to the user.What another often used on forcing press at present is the fluid pressure type protector, though this kind protector can overcome the scarce limit of all existence of rigidity protector, but, this kind protector overlaps independently hydraulic system owing to need be provided with one, not only has the high scarce limit of cost, simultaneously, also there is complex structure, the scarce limit that fault is higher.
Summary of the invention
The object of the present invention is to provide a kind of protector of forcing press, overcome the existing above-mentioned scarce limit of protector of existing forcing press.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: the protector of this a kind of forcing press comprises hydraulic cylinder, positioning and guiding flange, head, safety valve, bolt, hydraulic oil, sealing ring, accumulator, this invention has a hydraulic cylinder, middle part at hydraulic cylinder, by positioning and guiding flange and bolt, be fixed with head, described head inside is provided with accumulator, and the bottom of described head is equipped with safety valve, and the safety valve accumulator is connected; Be provided with sealing ring between head and the hydraulic cylinder, the middle airtight hydraulic oil that has of the endoporus of head and hydraulic cylinder; And the volume after the hydraulic oil compression is less than or equal to the volume of head top accumulator.
Operation principle: when the operating pressure of forcing press acted on the head, in case pressure surpasses the pressure that safety valve can bear, then safety valve was opened, and head moves downward, and hydraulic oil enters accumulator through safety valve, thereby arrived the effect of safeguard protection.
Beneficial effect: the present invention is simple in structure, and advantage easy to use can overcome existing forcing press rigidity protector simultaneously and converge the shortcoming of pressing protector.
Description of drawings
Accompanying drawing 1 is a structure principle chart of the present invention.Shown in the figure: 1. hydraulic cylinder, 2. positioning and guiding flange, 3. head, 4. safety valve, 5. bolt, 6. hydraulic oil, 7. sealing ring, 8. accumulator.
Specific implementation method
In the drawings, the protector of this a kind of forcing press comprises hydraulic cylinder 1, positioning and guiding flange 2, head 3, safety valve 4, bolt 5, hydraulic oil 6, sealing ring 7, accumulator 8, this invention has a hydraulic cylinder 1, middle part at hydraulic cylinder 1, by positioning and guiding flange 2 and bolt 5, be fixed with head 3, described head 3 inside are provided with accumulator 8, the bottom of described head 3 is equipped with safety valve 4, and safety valve 4 accumulators 8 are connected; Be provided with sealing ring 7 between head 3 and the hydraulic cylinder 1, head 3 and the middle airtight hydraulic oil 6 that has of the endoporus of hydraulic cylinder 1; And the volume after hydraulic oil 6 compressions is less than or equal to the volume of head 3 top accumulators 8.When the operating pressure of forcing press acted on the head 3, in case pressure surpasses the pressure that safety valve 4 can bear, then safety valve 4 was opened, and head 3 moves downward, and hydraulic oil enters accumulator 8 through safety valve 4, thereby arrived the effect of safeguard protection.
