Abstract
The utility model discloses a casting pressure system. The casting pressure system comprises a lower pressure casting roller corresponding to an upper pressure casting roller fixed horizontally in the axial direction, wherein the lower pressure casting roller is driven by an oil cylinder to perform horizontal movement; the oil cylinder is connected onto an oil tank and is driven by a pump to form an oil feed line and an oil return line; and a ball valve is arranged on each of the oil feed line and the oil return line neighboring the oil cylinder. By arranging high-pressure ball valves on the oil feed line and the oil return line of the oil cylinder, the casting pressure system provided by the utility model can avoid influences on normal production of the whole casting system caused by closing the ball valve after the pump has a sudden failure so as to ensure the casting capacity; and the pump can be maintained without stopping. Additionally, the pump only works at the early and final stages, and can be idle to avoid loss of the service life of the pump due to long-term uninterrupted work; and the ball valve can block off the oil feed line and the oil return line of the oil cylinder to ensure stable pressure in the oil cylinder, thereby ensuring casting thickness uniformity and improving casting quality.
Description
Technical field
The utility model relates to a kind of casting and presses system, belongs to aluminum technology for making field.
Background technology
In cast aluminium technical field, be all generally that upper die casting roller maintains static, and press down casting roll and move up and down to manufacture with respect to described upper die casting roller aluminium ingot or the aluminium foil of different-thickness.Be all generally to realize by oil cylinder oil inlet and oil return for pressing down moving up and down of casting roll at present, the oil-feed of oil cylinder or oil return are to drive by the pump on the pipeline between oil cylinder and oil cylinder.In actual job process, the potential burst dead electricity of pump or fault and cause pump normally to work, and then make the pressure release of oil cylinder automatic oil return, cause pressing down casting roll and decline and cannot normally work, the operation of final whole casting duration of impact, has reduced casting output.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of casting and presses system, pump occurs that catastrophic failure, by not affecting the normal operation of whole casting system, has ensured casting output, can under the prerequisite of not stopping, carry out maintenance activity to pump.
To achieve these goals, the technical solution of the utility model: a kind of casting presses system, it comprise the upper die casting roller that is fixedly installed with axial level corresponding press down casting roll, this presses down casting roll and moves horizontally up and down by hydraulic oil cylinder driving, and described oil cylinder is connected on fuel tank and driven and formed oil-feed and oil return circuit by pump, be provided with ball valve being in close proximity on the oil-feed of described oil cylinder and oil return circuit.
Further, described ball valve is that pressure is the high-pressure ball valve of 15MPa～20MPa; On the oil-feed between described oil cylinder and ball valve and oil return circuit, be provided with atmospheric valve; Described atmospheric valve is connected in described fuel tank by pipeline.
The beneficial effects of the utility model: by the oil-feed of oil cylinder and high-pressure ball valve is set above oil return circuit, in the time of operation, when pressing down and move to desired location in casting roll, oil cylinder control can close this high-pressure ball valve, like this, be that pump occurs that catastrophic failure also can not affect the normal operation of whole casting system, ensure casting output, can under the prerequisite of not stopping, carry out maintenance activity to pump; In addition, by the setting of this high-pressure ball valve, make the pump only need be in initial and ending operation work, can stop At All Other Times, avoid pump to make in long-time non-stop run the situation reducing its service life, simultaneously by oil-feed and the oil return circuit of high-pressure ball valve blocking-up oil cylinder, make in-oil cylinder pressure steadily stable, ensure upper die casting roller and pressed down the uniformity of the cast thickness between casting roll, improved castability.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation sketch of the present utility model.
Detailed description of the invention
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of casting as described in Figure 1 presses system, it comprise the upper die casting roller 1 that is fixedly installed with axial level corresponding press down casting roll 2, this presses down casting roll 2 and is driven up and down and moved horizontally by oil cylinder 3, and described oil cylinder 3 is connected on fuel tank 6 and driven and formed oil-feed and oil return circuits by pump 7, be provided with ball valve 4,5 being in close proximity on the oil-feed of described oil cylinder 3 and oil return circuit.
The utility model is by the oil-feed of oil cylinder 3 and high-pressure ball valve is set above oil return circuit, in the time of operation, oil cylinder 3 is controlled to press down while moving to desired location in casting roll 2 and can be closed this high-pressure ball valve, like this, be that pump 7 occurs that catastrophic failure also can not affect the normal operation of whole casting system, ensure casting output, can under the prerequisite of not stopping, carry out maintenance activity to pump 7; In addition, by the setting of this high-pressure ball valve, make 7 of the pumps need be in initial and ending operation work, can stop At All Other Times, avoid pump 7 to make in long-time non-stop run the situation reducing its service life, simultaneously by oil-feed and the oil return circuit of high-pressure ball valve blocking-up oil cylinder 3, make the pressure in oil cylinder 3 steadily stable, ensure upper die casting roller 1 and pressed down the uniformity of the cast thickness between casting roll 2, improved castability.
Described ball valve 4,5 is made as to the high-pressure ball valve that pressure is 15MPa～20MPa, to ensure described upper die casting roller 1 and to press down roll-force between casting roll 2 as 15MPa～20MPa, ensures the normal operation of whole casting system.
In addition, on the oil-feed between described oil cylinder 3 and ball valve 4,5 and oil return circuit, be provided with atmospheric valve 8, for working as pump 7 in the situation that not keeped in repair, when stopping operation, whole casting system, by this atmospheric valve 8, the pressure oil in oil cylinder 3 is carried out to emptying, reduce its service life to avoid the uninterrupted operation of this oil cylinder 3, otherwise, that is to say the service life of having improved oil cylinder 3.Preferably, described atmospheric valve 8 is connected in described fuel tank 6 by pipeline, pressure oil is recycled, improve the utilization rate of pressure oil, cost-saving.
The technical scheme above the utility model embodiment being provided is described in detail, applied principle and the embodiment of specific case to the utility model embodiment herein and set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in detailed description of the invention and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
