[0002] A threading machine is a device used to process pipe threads during pipeline installation. The oil pump circuit of a threading machine is an important component. Common threading machine oil pump circuits on the market typically connect an oil pipe to the bottom of the oil sump to allow oil to enter the pump, which then lubricates the threads through the oil pipe. However, the existing oil pump circuits are not designed reasonably and are not reliable enough. With increased use, the oil outlet hose is prone to blockage, and the accumulated oil in the oil circuit can easily lead to hose rupture. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide a threading machine oil pump circuit structure with reasonable structural design and reliable performance.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The oil pump circuit structure of this threading machine is a component of the threading machine. The threading machine is equipped with an oil sump assembly and a slide assembly. The oil pump of the threading machine is installed on the cover inside the threading machine and the rotor of the oil pump drives the flat wire and the gearbox drive shaft of the threading machine is connected. The oil pump circuit structure of the threading machine includes an oil pump inlet pipe and an oil pump outlet pipe. One end of the oil pump inlet pipe is connected to the oil sump assembly of the threading machine, and one end of the oil pump outlet pipe is connected to the slide assembly of the threading machine. Its structural features are: it also includes an oil sump inlet hose, a No. 1 tee connector, an inlet pipe, an outlet pipe, an outlet hose, and branch inlets. The system includes an oil pipe, an overpressure valve, a branch outlet pipe, and a No. 2 tee connector. The other end of the oil pump inlet pipe is connected to one end of the oil sump inlet hose. The other end of the oil sump inlet hose is connected to one end of the inlet pipe and one end of the branch outlet pipe via a No. 2 tee connector. The other end of the inlet pipe is connected to the oil pump inlet pagoda connector. The oil pump outlet pagoda connector is connected to one end of the outlet pipe. The other end of the outlet pipe is connected to one end of the outlet hose and one end of the branch inlet pipe via a No. 1 tee connector. The other end of the outlet hose is connected to the other end of the oil pump outlet pipe. The other end of the branch inlet pipe is connected to the other end of the branch outlet pipe via an overpressure valve.

[0005] Preferably, the threading machine oil pump circuit structure of this utility model further includes several locking buckles. The other end of the oil pump inlet pipe and one end of the oil sump inlet hose are connected by locking buckles. The other end of the oil inlet pipe and the oil pump inlet pagoda connector are connected by locking buckles. The oil pump outlet pagoda connector and one end of the outlet pipe are connected by locking buckles. The other end of the outlet hose and the other end of the oil pump outlet pipe are connected by locking buckles. Both ends of the overpressure valve are connected to the other end of the branch inlet pipe and the other end of the branch outlet pipe respectively through locking buckles.

[0006] Preferably, the oil pump of this invention is mounted on a cover located inside the threading machine using several internal hexagonal screws.

[0007] Compared with the prior art, this utility model has the following advantages and effects: simple structure and reasonable design.

Detailed Implementation

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0013] Example

[0014] See Figures 1 to 2 The threading machine is equipped with an oil sump assembly 13 and a carriage assembly 16. The oil pump 6 of the threading machine is mounted on a cover 15 located inside the threading machine, and the rotor of the oil pump 6 drives the flat wire and is connected to the gearbox drive shaft of the threading machine. Normally, the oil pump 6 is mounted on the cover 15 inside the threading machine by three Allen screws 14. For those skilled in the art, the oil sump assembly 13, the carriage assembly 16, the oil pump 6, and the cover 15 on the threading machine are common knowledge, and the installation relationship between these components is also common knowledge, so it will not be described in detail here.

[0015] The oil pump circuit structure of the threading machine in this embodiment includes an oil pump inlet pipe 1, an oil tank inlet hose 3, a No. 1 tee connector 4, an inlet pipe 5, an outlet pipe 7, an outlet hose 8, an oil pump outlet pipe 9, a branch inlet pipe 10, an overpressure valve 11, a branch outlet pipe 12, and a No. 2 tee connector 17.

[0016] In this embodiment, one end of the oil pump inlet pipe 1 is connected to the oil tank assembly 13 of the threading machine, and the other end of the oil pump inlet pipe 1 is connected to one end of the oil tank inlet hose 3. The other end of the oil tank inlet hose 3 is connected to one end of the inlet pipe 5 and one end of the branch outlet pipe 12 through a No. 2 tee connector 17. The other end of the inlet pipe 5 is connected to the inlet pagoda connector of the oil pump 6. The outlet pagoda connector of the oil pump 6 is connected to one end of the outlet pipe 7. The other end of the outlet pipe 7 is connected to one end of the outlet hose 8 and one end of the branch inlet pipe 10 through a No. 1 tee connector 4. The other end of the outlet hose 8 is connected to the other end of the oil pump outlet pipe 9. One end of the oil pump outlet pipe 9 is connected to the slide assembly 16 of the threading machine. The other end of the branch inlet pipe 10 is connected to the other end of the branch outlet pipe 12 through an overpressure valve 11.

[0017] Typically, the threading machine oil pump circuit structure in this embodiment may also include several locking buckles 2. The other end of the oil pump inlet pipe 1 and one end of the oil tank inlet hose 3 are connected by locking buckles 2. The other end of the oil inlet pipe 5 and the oil inlet pagoda connector of the oil pump 6 are connected by locking buckles 2. The oil outlet pagoda connector of the oil pump 6 and one end of the oil outlet pipe 7 are connected by locking buckles 2. The other end of the oil outlet hose 8 and the other end of the oil pump outlet pipe 9 are connected by locking buckles 2. Both ends of the overpressure valve 11 are connected to the other end of the branch inlet pipe 10 and the other end of the branch outlet pipe 12 respectively through locking buckles 2.

[0018] As can be seen from the above, in this embodiment, the oil pump circuit structure of the threading machine first connects one end of the oil pump inlet pipe 1 to the oil sump assembly 13, and the other end of the oil pump inlet pipe 1 is fixed to the oil sump inlet hose 3 through the locking buckle 2. The oil sump inlet hose 3 is connected to the inlet pipe 5 and the branch outlet pipe 12 through the No. 2 tee connector 17. The inlet pipe 5 is then fixed to the oil pump 6's inlet pagoda connector using the locking buckle 2. The oil pump 6 is connected to the cover 15 inside the threading machine through three internal hexagon screws 14, which drive the flat wire and the threading machine speed change. The oil pump 6 is connected to the drive shaft. The oil outlet pagoda connector of the oil pump 6 is fixed to the oil outlet pipe 7 by the locking buckle 2. The oil outlet pipe 7 is divided into two paths by the No. 1 tee connector 4: one path is connected to the oil outlet hose 8, and the oil outlet hose 8 is connected to the oil pump outlet pipe 9 by the locking buckle 2. Finally, the oil pump outlet pipe 9 is fixed to the threading machine slide assembly 16; the other path is connected to the branch oil inlet pipe 10. The branch oil inlet pipe 10 and the branch oil outlet pipe 12 are connected by the overpressure valve 11. The two ends of the overpressure valve 11 are fixed to the branch oil outlet pipe 12 and the branch oil inlet pipe 10 by the locking buckle 2 respectively.

[0019] In this embodiment, the oil pump circuit structure of the threading machine is based on the fact that when the threading machine motor is working, it drives the rotor inside the oil pump 6 to rotate through the transmission component, generating suction. When the oil pump 6 is working, the oil in the oil tank assembly 13 passes through the oil pump inlet pipe 1, through the oil tank inlet hose 3 and the inlet pipe 5, and then enters the oil pump 6. Driven by the oil pump 6, it enters the outlet pipe 7, and then passes through the No. 1 tee connector 4 and splits into two paths: one path passes through the outlet hose 8 and the oil pump outlet pipe 9, and finally enters the carriage assembly 16; the other path passes through the branch inlet pipe 10 and reaches the overpressure valve 11. During normal operation, the internal hydraulic pressure of the threading machine oil pump circuit structure cannot make the overpressure valve 11 reach the opening pressure. That is to say, when the threading machine is working normally, the overpressure valve 11 is in the closed state, so this path of oil is cut off at the overpressure valve 11.

[0020] After the threading machine has been working for a long time, the oil outlet hose 8 may become blocked. At this time, a certain pressure will be generated in the oil inlet pipe 5, which will increase the hydraulic pressure inside the oil pump circuit structure of the threading machine. When the hydraulic pressure inside the oil circuit exceeds the opening pressure of the overpressure valve 11, the valve core of the overpressure valve 11 is pushed open, and the valve port of the overpressure valve 11 opens, which will guide the oil and flow to the branch oil outlet pipe 12, so that the oil in the oil circuit returns to the No. 2 tee joint 17 between the oil inlet hose 3 and the oil inlet pipe 5, and then forms a return oil circuit. The oil returns to the oil inlet pipe 5 again, forming a self-circulation of the oil circuit. This effectively avoids the oil outlet hose 8 from bursting due to excessive pressure, and greatly improves the overall performance of the threading machine.

[0021] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, all of which should fall within the protection scope of this utility model.
