Description

Technical Field

[0001] The utility model relates to the technical field of magnetic tile production, in particular to an oil tank structure of an oil pump station for a permanent magnet automatic hydraulic press. Background Art

[0002] In the production process of wet magnet die-casting, after the amount of material delivered by the feeding system to the die-casting mold reaches the standard, it is necessary to use a permanent magnet automatic hydraulic press in conjunction with the die-casting mold to die-cast the material. During the die-casting process, the two opposing cylinders of the permanent magnet automatic hydraulic press are required to drive the die-casting mold to die-cast the material.

[0003] At present, permanent magnet automatic hydraulic presses usually require an external oil pump station to transport hydraulic oil to their telescopic cylinders to provide sufficient hydraulic pressure for the telescopic cylinders. The two opposing telescopic cylinders of the permanent magnet automatic hydraulic press are both supplied with oil by the oil pump of the oil pump station. The hydraulic oil has a complex route and metal debris is more likely to appear in the hydraulic oil. The oil tank of a traditional oil pump station usually has only one containing area. The metal debris in the hydraulic oil is in a disturbed state. During the process of the oil pump pumping oil out, the metal debris is very likely to re-enter the oil pump, which can easily cause damage to the oil pump impeller.

[0004] In order to solve the problem that metal debris easily flows with the hydraulic oil, causing the oil pump to be easily damaged, the inventor designed an oil tank structure for an oil pump station for a permanent magnet automatic hydraulic press, and thus proposed the present application. Utility Model Content

[0011] The flow route of the liquid oil in the tank body is: dynamic oil return area, oil outlet, static buffer area, oil hole, static oil distribution area, and the flow route is L-shaped.

[0012] Optionally, the shape of the oil passage port is any one of circular, rectangular or elliptical;

[0013] There are multiple oil holes, and the multiple oil holes are evenly distributed on the second orifice plate in a rectangular or circular array.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] like Figures 1 to 3 As shown, this embodiment provides an oil tank structure of an oil pump station for a permanent magnet automatic hydraulic press, including a tank body 10 of an oil storage tank, wherein the tank body 10 is provided with a first partition 11 and a second partition 12 for dividing the oil storage tank into a dynamic oil return area 13, a static buffer area 14 and a static oil distribution area 15, and the dynamic oil return area 13, the static buffer area 14 and the static oil distribution area 15 are interconnected through the first partition 11 and the second partition 12.

[0032] In this embodiment, the first partition 11 and the second partition 12 are provided, and the oil storage tank of the tank body 10 is divided into three areas: a dynamic oil return area 13, a static buffer area 14, and a static oil distribution area 15 by using the first partition 11 and the second partition 12. This can prevent the oil return action and oil discharge action of the oil pump station from disturbing the liquid oil in the static buffer area 14, so that the metal debris in the liquid oil can naturally sink to the bottom, which can effectively solve the current problem of metal debris flowing with the liquid oil and causing damage to the oil pump.

[0033] Therefore, the core concept of the present application is to divide an entire oil storage tank into multiple areas so that the liquid oil in at least one of the areas is in a relatively static state, and utilize the density difference between the liquid oil and the metal debris to allow the metal debris to naturally sink to the bottom in a relatively static state, thereby completing the filtration of the metal debris and solving the problem of the oil pump being easily damaged due to the flow of metal debris with the liquid oil.

[0034] Specifically, in this embodiment, if Figures 1 to 3 As shown, the volume of the static buffer area 14 is smaller than the volume of the dynamic oil return area 13 and the volume of the static oil distribution area 15 .

[0035] Specifically, in this embodiment, if Figures 1 to 3 As shown, the first partition 11 and the second partition 12 are both arranged vertically, and the two ends of the second partition 12 are respectively fixed to the two opposite side walls of the tank body 10, one end of the second partition 12 is fixed to the side wall of the tank body 10, and the other end is fixed to the second partition 12. In this embodiment, Figures 1 to 3The second partition 12 divides the oil storage tank into two areas, and the first partition 11 divides one of the two divided areas into two again, forming three areas.

[0036] Specifically, in this embodiment, if Figures 1 to 3 As shown, the first partition plate 11 and the second partition plate 12 are arranged perpendicular to each other, the first partition plate 11 is provided with an oil through port 112, and the second partition plate 12 is provided with an oil through hole 121, and the axes of the oil through port 112 and the oil through hole 121 are perpendicular to each other;

[0037] The liquid oil flows through the tank body 10 through the dynamic oil return area 13, the oil port 112, the static buffer area 14, the oil hole 121, and the static oil distribution area 15, and the flow route is L-shaped.

[0038] The flow path of the liquid oil in the oil storage tank in this embodiment is L-shaped, so that after the liquid oil flows from the dynamic oil return area 13 into the static buffer area 14, the liquid oil will not flow directly into the static oil distribution area 15, but there is a truncation and deceleration process, which is conducive to the sinking of metal debris and prevents the metal debris from flowing directly into the static oil distribution area 15 along with the liquid oil.

[0039] Specifically, in this embodiment, if Figures 1 to 3 As shown, the shape of the oil passage port 112 is any one of a circular, rectangular or elliptical shape;

[0040] There are multiple oil holes 121, and multiple oil holes 121 are evenly distributed on the second orifice plate in a rectangular or circular array. In this embodiment, the shape of the oil port 112 is rectangular, and technicians can also set it to other shapes such as a circle, a regular polygon, etc. according to needs. In this embodiment, there is only one oil port 112, and its size is much larger than the size of the oil hole 121, which is convenient for metal debris to enter the static buffer zone with the liquid oil. There are multiple oil holes 121, which can prevent large metal debris from directly entering the static oil distribution area 15. The oil holes 121 in this embodiment are distributed in a rectangular array.

[0041] Specifically, in this embodiment, if Figures 1 to 3 As shown, the bottom of the side wall of the tank body 10 is provided with a first oil drain joint 101, a second oil drain joint 102, and a third oil drain joint 103 which are respectively connected to the dynamic oil return area 13, the static buffer area 14, and the static oil distribution area 15;

[0042] The horizontal positions of the first oil drain joint 101, the second oil drain joint 102, and the third oil drain joint 103 are all lower than the oil through port 112 and the oil through hole 121. By providing the first oil drain joint 101, the second oil drain joint 102, and the third oil drain joint 103, it is convenient to discharge the liquid oil during the subsequent oil pump station inspection and maintenance.

[0043] Specifically, in this embodiment, if Figures 1 to 3 As shown, the first baffle 11 is provided with a first overflow notch 111, and the second baffle 12 is provided with a second overflow notch 122, and the bottom height of the first overflow notch 111 is lower than the bottom height of the second overflow notch 122. By providing the first overflow notch 111 and the second overflow notch 122, and the bottom height of the first overflow notch 111 is lower than the bottom height of the second overflow notch 122, when there is sufficient oil in the oil storage tank, liquid oil is prevented from flowing directly from the overflow tank from the dynamic oil return area 13 to the static oil distribution area 15, but flows from the static oil distribution area 15 to the static buffer area 14, and then flows into the dynamic oil return area 13.

[0044] Specifically, in this embodiment, if Figures 1 to 3 As shown, the side wall of the tank body 10 is also provided with a first pump oil port 106 and a second pump oil port 107 both connected to the static oil distribution area 15, and the first pump oil port 106 and the second pump oil port 107 are arranged on the same side wall or on two opposite side walls of the tank body 10. By providing two pump oil interfaces, the two telescopic cylinders of the permanent magnet automatic hydraulic press can be respectively equipped with corresponding oil pumps to complete the offset top pressure.

[0045] Specifically, in this embodiment, if Figures 1 to 3 As shown, metal debris filters are installed on the first pump oil port 106 and the second pump oil port 107. The metal debris filter can further prevent the metal debris that has not settled to the bottom from entering the oil pump and damaging the oil pump. The metal debris filter in this embodiment adopts a filter screen, and technicians can choose other types of filters according to needs.

[0046] Specifically, in this embodiment, if Figure 2 and Figure 3 As shown, the side wall of the tank body 10 is also provided with a first observation window 104 and a second observation window 105 for respectively observing the dynamic oil return area 13 and the static buffer area 14. By providing the first observation window 104 and the second observation window 105, the liquid oil state of the second observation window 105 can be observed conveniently and timely.
