Abstract
The utility model discloses a fast oil cylinder for a small-table-board large-tonnage hydraulic press. The fast oil cylinder comprises a cylinder body, wherein a liquid filling valve installation cavity is formed in the top center of the cylinder body; a rodless oil chamber port is formed near the liquid filling valve installation cavity; a speed increasing rod oil inlet is formed in the top side of the cylinder body; a piston is inserted and sheathed in the cylinder body; a speed increasing rod is inserted and sheathed in the center of the piston; one end of the speed increasing rod is fixedly arranged on the internal bottom face of the cylinder body; a speed increasing oil chamber is formed in the center of the speed increasing rod; the speed increasing oil chamber is communicated with the speed increasing rod oil inlet. According to the structure of the fast oil cylinder for the small-table-board large-tonnage hydraulic press, as the speed increasing rod oil inlet which is originally formed in the top of the cylinder body is formed in the side face of the cylinder body, the usable area of the top of the cylinder body is increased; as multiple original smaller liquid filling valve installation cavities are changed into one larger liquid filling valve installation cavity, the cylinder body is simpler in structure, the processing technology is simplified, and the processing cost is reduced; meanwhile, a larger liquid filing valve is installed, so that the oil feeding speed is higher; therefore, the working speed of the oil cylinder is improved greatly.
Description
technical field:
The utility model relates to hydraulic equipment technical field, relates in particular to hydraulic equipment Quick cylinder.
background technique:
When existing little table top great tonnage hydraulic machine does not reach required speed by deadweight, master cylinder adopts Quick cylinder, by increase speedup bar in oil cylinder, realize, in current Quick cylinder, oil cylinder speedup bar filler opening is in oil cylinder top center, for increasing flow, liquid-filling valve is arranged in both sides, top, in both sides, oil cylinder top, offer two little liquid-filling valves cavity is installed, but make like this cylinder structure complicated, process loaded down with trivial details, cost is high, and two little liquid-filling valves are installed are made oil-feed flow little, does not reach the requirement of quick work.
model utility content:
The purpose of this utility model is exactly in order to solve existing issue, and a kind of little table top great tonnage hydraulic machine Quick cylinder is provided, and makes housing structure simpler, simplified processing process, cut down finished cost, larger liquid-filling valve is installed simultaneously and is made oil-feed speed faster, greatly improved oil cylinder operating rate.
Technology solution of the present utility model is as follows:
Little table top great tonnage hydraulic machine Quick cylinder, include cylinder body, described cylinder body top center has liquid-filling valve cavity is installed, liquid-filling valve is installed cavity side and is had without bar oil pocket mouth, side of cylinder block has speedup bar filler opening, and cylinder interior is inserted with piston, and piston center is inserted with speedup bar, speedup bar one end is fixed on oil cylinder inner bottom surface and center has speedup oil pocket, and speedup oil pocket is connected with speedup bar filler opening.
As preferably, described speedup bar filler opening, between liquid-filling valve installation cavity bottom surface and cylinder interior bottom surface, forms level and vertical rectangular shape passage between speedup bar filler opening and speedup oil pocket.
As preferably, described without bar oil pocket mouth and liquid-filling valve, cavity be installed and be all connected with cylinder interior.
The beneficial effects of the utility model are:
The utility model structure changes out original speedup bar filler opening of opening at cylinder body top at side of cylinder block into, cylinder body top usable area is increased, by original, offer a plurality of less liquid-filling valve installation cavity structural reforms for offering a larger liquid-filling valve installation cavity, make housing structure simpler, simplified processing process, cut down finished cost, larger liquid-filling valve is installed simultaneously and is made oil-feed speed faster, greatly improved oil cylinder operating rate.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
In figure: 1, cylinder body; 2, piston; 3, speedup bar; 4, speedup oil pocket; 5, liquid-filling valve is installed cavity; 6, without bar oil pocket mouth; 7, speedup bar filler opening; 8, rectangular shape passage.
embodiment:
As shown in Figure 1, little table top great tonnage hydraulic machine Quick cylinder, include cylinder body 1, described cylinder body 1 top center has liquid-filling valve cavity 5 is installed, and liquid-filling valve is installed cavity 5 sides and had without bar oil pocket mouth 6, and cylinder body 1 top-side has speedup bar filler opening 7, cylinder body 1 inside is inserted with piston 2, piston 2 centers are inserted with speedup bar 3, and cylinder body 1 inner bottom surface is fixed in speedup bar 3 one end and center has speedup oil pocket 4, and speedup oil pocket 4 is connected with speedup bar filler opening 7.
Particularly, described speedup bar filler opening 7 is between liquid-filling valve installation cavity 5 bottom surfaces and cylinder body 1 inner bottom surface, and speedup bar filler opening 7 and 4 of speedup oil pockets form level and vertical rectangular shape passage 8.
Particularly, describedly without bar oil pocket mouth 6 and liquid-filling valve, cavity 5 is installed and is all connected with cylinder body 1 inside.
Working principle of the present utility model is: liquid oils enters the speedup oil pocket 4 of speedup bar 3 by speedup bar filler opening 7, the liquid-filling valve that liquid-filling valve is installed in cavity 5 simultaneously is also filled with liquid oils in cylinder body 1, thereby promote piston 2 work, because liquid-filling valve is improved oil-feed speed after being replaced with large liquid-filling valve, accelerated the movement velocity of piston 2.
The foregoing is only preferred embodiment of the present utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all should belong to the scope of the utility model protection.
