Abstract
The utility model discloses a big heavy hydraulic press off -load system of freely forging belongs to big heavy type and freely forges hydraulic press hydraulic system, hydraulic system includes the oil pipeline of off -load system, hydro -cylinder, hydraulic power unit and intercommunication hydraulic power unit and hydro -cylinder, the off -load system includes the unloading valve piece, its characterized in that: the setting of unloading valve piece on hydraulic power unit or hydraulic power unit close on the position, unloading valve piece oil inlet is linked together with oil pipeline, unloading valve piece oil -out and hydraulic power unit intercommunication.
Description
Technical field
The utility model relates to forcing press off-load field, especially for the position of sound production of large heavy punching press, forging and stamping used oil press unloader block, is specially large heavy open die forging hydraulic press Load Relief System.
Background technology
Along with the industrialized development of China, manufacturing industry level improves constantly, to workpiece combination property, the requirement of production efficiency is also more and more higher, in this case, various punching, forging hydraulic press is widely used, hydraulic press plays key player in processing and manufacturing process, therefore each hydraulic press manufacturer constantly makes great efforts to improve this producer hydraulic press design level, to meet the need of market, but manufacturer often focuses on the improvement of large parts, and have ignored the tiny but improvement of successful, the position of such as unloader block is selected, the effect of unloader block be after oil cylinder has pressurizeed-oil cylinder promote before very short time section in by the pressure release of oil cylinder inner high voltage fluid, traditional design concept is: unloader block is more near better apart from oil cylinder, so that oil cylinder pressure release, so unloader block is all placed in press top near oil cylinder oil inlet mouth place.
But in actual production process, there will be following problem when hydraulic press runs: 1, during hydraulic press work, its this cognition shakes, unloader block is that bolt is fixed or is welded and fixed and all can frequently come off; 2, press body temperature is high, and hot-air rises, and unloader controls lower road and electromagnetic component easily damages; 3, unloader block breaks down repairing or everyday devices when patrolling and examining, and all must shut down, employ driving, cage, holding time is many, impact production; 4, because press headroom is little, no matter so workload size, can only one man operation, and also danger coefficient is high.
Summary of the invention
The purpose of this utility model is to provide a kind of large heavy open die forging hydraulic press Load Relief System, and unloader block is wherein arranged on more rational position, can reduce equipment failure rate, and facilitates maintenance of equipment and maintenance.
For achieving the above object, the scheme that the utility model is taked is: large heavy open die forging hydraulic press Load Relief System, belong to large heavy open die forging hydraulic press hydraulic system, described hydraulic system comprises the Load Relief System with unloader block, oil cylinder, hydraulic power unit and the oil pipeline being communicated with hydraulic power unit and oil cylinder, described unloader block is arranged on hydraulic power unit or hydraulic power unit adjacent locations, to facilitate maintenance, unloader block oil-in is connected with oil pipeline, unloader block oil-out is communicated with hydraulic power unit, during off-load, hydraulic oil in oil pipeline leaks into hydraulic power unit by unloader block.
As optimization, near hydraulic power unit oil-out position welding tee on described oil pipeline, unloader block oil-in is connected with oil pipeline by described threeway, to facilitate installation, reduces workload.
Pascal's law is pointed out, after in incompressible stationary fluid, any point produces pressure increment by external force, this pressure increment instantaneous time reaches stationary fluid each point, its principle is, due to the mobility of liquid, the pressure change of certain part generation of the stationary fluid in closed container, by size unchangeably to all directions transmission.
Find in actual use, the utility model beneficial effect clearly: because unloader block leaves hydraulic press body, its environment temperature reduces, and control circuit and electromagnetic component fault rate decline; Be convenient to everyday devices inspection and safeguard, finding that fault is timely; Repairing is convenient, ensure that the safety of service worker, and saves the maintenance time of at least four times, monthly saves 10 hours maintenance time, according to 4.5 tons of Production rate per hour, monthly can improve output about 45 tons, can improve output about 540 tons every year.
Accompanying drawing explanation
Fig. 1 is prior art hydraulic press unloader block position view.
Fig. 2 is according to the utility model unloader block position view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme of utility model is described in detail.
Figure 1 shows that prior art hydraulic press unloader block position view, unloader block 1 is positioned at hydraulic press top near oil cylinder 2 oil-in place, and during pressure release, hydraulic oil leaks into the fuel tank 8 of unloader block 1 upper end; The utility model scheme as shown in Figure 2, unloader block 1 is arranged on hydraulic power unit 4, oil pipeline 3 closes on the oil-out place welding tee 6 of hydraulic power unit 4, threeway 6 is by the inlet communication of pipeline 5 with unloader block 1, the outlet of unloader block is communicated with hydraulic power unit 4 by pipeline 7, during pressure release, hydraulic oil directly leaks in the fuel tank of hydraulic power unit 4.
Use through long-time, the press off-load in above-described embodiment is normal, and fault rate obviously reduces, maintenance, easy to maintenance, also provides guarantee to safety of workers operation simultaneously; Compared with the similar press of prior art, monthly save 10 hours maintenance time, according to 4.5 tons of Production rate per hour, monthly can improve output about 45 tons, output about 540 tons can be improved every year.
The above is only preferred embodiment of the present utility model; protection domain of the present utility model is also not only confined to above-described embodiment; all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model; should be understood that; for those skilled in the art; do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
