Description

Technical Field

[0001] The invention relates to the technical field of oil presses, in particular to a flow self-regulating hydraulic system. Background Art

[0002] The function of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components (accessories) and hydraulic oil. Hydraulic systems can be divided into two categories: hydraulic transmission systems and hydraulic control systems.

[0003] Hydraulic presses can be divided into water presses and oil presses, among which oil presses use hydraulic oil as the working medium. Because hydraulic oil has a relatively suitable viscosity, good sealing effect, and lubrication effect, oil presses have been widely used. When the oil press is in use, the oil in the hydraulic oil tank is pumped into the oil pipe through the machine pump, and then sent to the hydraulic telescopic rod through the oil pipe, so that the hydraulic telescopic rod can complete the telescopic operation. When the existing oil press is performing the oil delivery operation, it is not convenient to adjust the flow rate of the oil passing through the first oil pipe. Summary of the invention

[0004] The purpose of the embodiment of the present invention is to provide a flow self-adjusting hydraulic system, aiming to solve the following problem: when the existing hydraulic press is performing oil delivery operation, the flow of oil passing through the first oil delivery pipe cannot be conveniently adjusted.

[0010] The oil suction assembly is arranged on the second oil delivery pipe and the hydraulic oil tank, and is used for absorbing the hydraulic oil seeping out from the connection between the hydraulic telescopic rod and the second oil delivery pipe.

[0011] Furthermore, the flow control component includes:

[0012] A support member connected to the inner wall of the sleeve member;

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] like Figure 1-Figure 3 As shown, a flow self-adjusting hydraulic system provided by an embodiment of the present invention comprises a hydraulic oil tank 1, a first oil delivery pipe 2, a second oil delivery pipe 3, a hydraulic telescopic rod support 8 and a hydraulic telescopic rod 7, wherein the hydraulic telescopic rod support 8 is connected to the surface of the hydraulic oil tank 1, the hydraulic telescopic rod 7 is installed inside the hydraulic telescopic rod support 8, the second oil delivery pipe 3 is connected to one end of the hydraulic telescopic rod 7, and one end of the first oil delivery pipe 2 is arranged inside the hydraulic oil tank 1, and the flow self-adjusting hydraulic system further comprises:

[0033] The sleeve 13 is connected between the second oil pipeline 3 and the first oil pipeline 2, and one end of the second oil pipeline 3 away from the hydraulic telescopic rod 7 and one end of the first oil pipeline 2 away from the hydraulic oil tank 1 are both arranged inside the sleeve 13;

[0034] A flow control component, disposed on the sleeve 13, for adjusting the flow of the hydraulic oil flowing into the second oil delivery pipe 3;

[0035] A limit assembly, disposed on the side of the sleeve 13, for limiting the position of the flow control assembly; and

[0036] The oil suction assembly is arranged on the second oil delivery pipe 3 and the hydraulic oil tank 1 , and is used to absorb the hydraulic oil seeping out from the connection between the hydraulic telescopic rod 7 and the second oil delivery pipe 3 .

[0037] In one embodiment of the present invention, the socket 13 can be a socket cover, and the flow control component and the limit component cooperate with each other to change the size of the inner cross-section of the socket 13 to control the flow of the hydraulic oil passing through the socket 13, and this cooperation method is simple to adjust and the flow control is accurate. When the machine pump on the hydraulic oil tank 1 injects the hydraulic oil into the hydraulic telescopic rod 7 through the first oil pipe 2, there is usually a problem that some hydraulic oil will seep out of the connection between the second oil pipe 3 and the hydraulic telescopic rod 7. By arranging an oil suction component on the second oil pipe 3 and the hydraulic oil tank 1, the leaked hydraulic oil can be fully absorbed and cleaned up, and further, the hydraulic oil can be collected.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the flow control component includes:

[0039] A support member 11 connected to the inner wall of the sleeve member 13;

[0040] The hinge 18 is installed on the outside of the support member 11 , and the surface of the hinge 18 is connected with the flow control member 10 . The flow control member 10 is rotatably connected to the side of the hydraulic oil tank 1 through the hinge 18 .

[0041] In this embodiment, the limiting component includes:

[0042] A threaded hole 12 is formed on a side of the sleeve 13, and a moving part 16 is connected to the inside of the threaded hole 12; and

[0043] The limiting member 15 is installed at one end of the moving member 16 , and the outer surface of the limiting member 15 is smooth. A torsion column 17 is installed at one end of the moving member 16 .

[0044] In this embodiment, the limit assembly further includes:

[0045] A pressure sensor 19 mounted on the surface of the flow control member 10; and

[0046] The pressure display 14 is installed on the outside of the sleeve 13 , and the pressure display 14 is electrically connected to the pressure sensor 19 .

[0047] In this embodiment, the support member 11 may be a support block, the flow control member 10 may be a movable plate, the moving member 16 may be a threaded rod, and the stop member 15 may be an elliptical stop block;

[0048] The first oil delivery pipe 2 delivers the hydraulic oil into the interior of the socket 13, and then injects it into the interior of the second oil delivery pipe 3 through the socket 13. When the hydraulic oil passes through the socket 13, the hydraulic oil will pressurize the flow control member 10, so that the flow control member 10 rotates on the support member 11 through the hinge 18, and the limiter 15 arranged above the flow control member 10 will limit the flow control member 10, so that the gap between the two flow control members 10 is in a suitable position to achieve the purpose of flow regulation, and when the flow control member 10 rotates and abuts against the limiter 15, the limiter 15 will limit the flow control member 10. The pressure sensor 19 on the component 10 applies pressure. Since the pressure sensor 19 and the pressure display 14 are electrically connected, the user can also know the pressure caused by the limit member 15 on the pressure sensor 19 by observing the pressure display 14. The user can further adjust the position of the limit member 15 to adjust the gap between the two flow control components 10. At this time, the torsion column 17 is rotated by hand so that the torsion column 17 drives the movable member 16 to move left and right inside the threaded hole 12, thereby making the two limit members 15 move away from or close to each other to increase the gap between the two flow control components 10, that is, to adjust the flow size.

[0049] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the oil absorption assembly comprises:

[0050] The telescopic member 4 is installed on the outside of the second oil pipeline 3; and

[0051] The mounting member 5 is connected to one end of the telescopic member 4 , and an oil-absorbing member 6 is installed on the surface of the mounting member 5 . Both the mounting member 5 and the oil-absorbing member 6 are sleeved on the outside of the second oil delivery pipe 3 .

[0052] In this embodiment, a collecting member 9 is placed on the surface of the hydraulic oil tank 1 , and the collecting member 9 is arranged below the mounting member 5 and the oil suction member 6 .

[0053] In this embodiment, the telescopic member 4 may be an electric telescopic rod, the mounting member 5 may be a connecting ring plate, the oil absorbing member 6 may be an oil absorbing sponge block, and the collecting member 9 may be a collecting tank;

[0054] When the second oil pipeline 3 is injecting oil into the hydraulic telescopic rod 7, the side surface of the oil suction piece 6 should be in contact with the surface of the hydraulic telescopic rod 7, so that the oil seeping from the interface between the second oil pipeline 3 and the hydraulic telescopic rod 7 is absorbed by the oil suction piece 6. When the oil suction piece 6 absorbs more hydraulic oil, the telescopic piece 4 can be opened. The telescopic piece 4 drives the mounting piece 5 and the oil suction piece 6 to press against one end of the hydraulic telescopic rod 7, so that the hydraulic oil in the oil suction piece 6 is squeezed out, and the squeezed hydraulic oil will drip into the collecting piece 9 and be collected.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
