Description

Technical Field

[0001] The utility model relates to the technical field of lubricating equipment for pipe benders, in particular to a leakage-proof lubricating device for pipe benders. Background Art

[0002] A pipe bender is a machine used for bending pipes that can also be used as a jack. The pipes are bent using a pipe bender. During the bending process, in order to improve the quality of the pipes, a lubrication device is required to regularly lubricate the contact area between the core head and the straight pipe.

[0003] The utility model patent with announcement number CN218310458U discloses a lubrication device for a pipe bending machine. Since the lubricating oil is sprayed out after the core head is inserted into place, the lubricating oil is applied to the accurate position, the amount of lubricating oil used is small, and the lubrication effect is good. However, during the implementation of the patent, due to the lack of an anti-leakage structure, after the lubrication is completed, excess oil is likely to continue to flow out from the inside of the core rod, which not only easily causes waste of lubricating oil, but also easily causes pollution to the forming machine. Therefore, the utility model provides a leakage-proof lubrication device for a pipe bending machine to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a leakage-proof lubricating device for a pipe bending machine to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leakage-proof lubrication device for a pipe bending machine, comprising an oil filling pipe and an oil inlet pipe, a semicircular buffer mixing bin is installed at the bottom of the oil filling pipe, and an anti-leakage baffle is installed inside the oil filling pipe, a return spring is installed at the bottom of the anti-leakage baffle, and the end of the return spring away from the anti-leakage baffle is connected to the oil filling pipe, an oil inlet pipe is installed at the top of the oil filling pipe, and an oil supply pipe is installed on the outside of the oil inlet pipe.

[0006] Preferably, a spiral tube is installed at the bottom of the semicircular buffer mixing bin, and a core head is installed at the bottom of the spiral tube, and lubricating oil spray ports are evenly arranged on the outer side of the core head.

[0007] Preferably, both ends of the oil filling pipe are equipped with a counter-flow guide pipe, and the end of the counter-flow guide pipe away from the oil filling pipe is connected to the semicircular buffer mixing chamber.

[0008] Preferably, a filter is installed inside the oil inlet pipe.

[0009] Preferably, a sealing pipe cover is installed on the top of the oil inlet pipe.

[0010] Preferably, guide grooves are provided at the bottoms of both ends of the oil filling pipe, and guide sliders are slidably installed inside the guide grooves. An L-shaped connecting rod is installed at the end of the guide slider away from the guide groove, and the end of the L-shaped connecting rod away from the guide slider is connected to the anti-leakage baffle.

[0011] Preferably, an anti-rust layer is provided on the outer side of the return spring.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The anti-leakage pipe bending machine lubrication device is equipped with an oil filling pipe, a return spring and an anti-leakage baffle. During the lubrication process, the oil supply pump draws lubricating oil into the oil filling pipe, which increases the oil pressure inside the oil filling pipe. At this time, the anti-leakage baffle is forced to move, so that the anti-leakage baffle no longer blocks the counter-drain pipe, and the oil can be discharged through the counter-drain pipe. After the lubrication is completed, the oil supply process is stopped, the oil pressure inside the oil filling pipe is reduced, and the return spring can push the anti-leakage baffle to move and reset, so that the anti-leakage baffle blocks the counter-drain pipe again, thereby preventing the oil from continuing to leak through the counter-drain pipe, thereby avoiding oil waste.

[0014] 2. The anti-leakage pipe bending machine lubrication device is equipped with a spiral tube, a hedging guide tube and a semicircular buffer mixing chamber. When the oil enters the semicircular buffer mixing chamber through the two sets of hedging guide tubes, since the two sets of hedging guide tubes are installed opposite to each other, the oil can be sprayed out through the two sets of hedging guide tubes and impact each other inside the semicircular buffer mixing chamber, which not only reduces the impact force of the oil and plays a buffering role, so that the oil can flow out evenly, but also can fully mix the oil. At the same time, after the oil enters the spiral tube, the spiral structure of the spiral tube can stir the oil, so that the oil impacts each other, which can play the effect of mixing the oil again, so that the lubricating oil composition remains uniform, ensuring the lubrication effect;

[0015] 3. The anti-leakage pipe bending machine lubrication device is equipped with an oil inlet pipe, a filter and an oil supply pipe. When the lubricating oil enters the oil inlet pipe, the impurities in the oil can be filtered through the filter. After use, the sealing pipe cover can be opened to clean the impurities attached to the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3 The utility model provides an embodiment: a leakage-proof lubrication device for a pipe bending machine, comprising an oil filling pipe 4 and an oil inlet pipe 7, a semicircular buffer mixing bin 11 is installed at the bottom of the oil filling pipe 4, and an anti-leakage baffle 6 is installed inside the oil filling pipe 4, a reset spring 5 is installed at the bottom of the anti-leakage baffle 6, and the end of the reset spring 5 away from the anti-leakage baffle 6 is connected to the oil filling pipe 4, an anti-rust layer is provided on the outside of the reset spring 5, which is beneficial to prolonging the service life of the reset spring 5, an oil inlet pipe 7 is installed on the top of the oil filling pipe 4, and an oil supply pipe 10 is installed on the outside of the oil inlet pipe 7.

[0022] like Figure 1-2 As shown, a spiral tube 2 is installed at the bottom of the semicircular buffer mixing chamber 11, and a core head 1 is installed at the bottom of the spiral tube 2. Lubricating oil spray ports 12 are evenly arranged on the outside of the core head 1. After the oil enters the spiral tube 2, the spiral structure of the spiral tube 2 can stir the oil, so that the oil impacts each other, which can play the role of mixing the oil again, so that the lubricating oil composition remains uniform, ensuring the lubrication effect.

[0023] like Figure 1-2 As shown, both ends of the oil filling pipe 4 are equipped with a counter-flow guide pipe 3, and the end of the counter-flow guide pipe 3 away from the oil filling pipe 4 is connected to the semicircular buffer mixing chamber 11. When the oil enters the semicircular buffer mixing chamber 11 through the two groups of counter-flow guide pipes 3, since the two groups of counter-flow guide pipes 3 are installed opposite to each other, the oil can be sprayed out through the two groups of counter-flow guide pipes 3 and impact each other inside the semicircular buffer mixing chamber 11, which not only reduces the impact force of the oil and plays a buffering role, so that the oil can flow out evenly, but also can make the oil fully mixed.

[0024] like Figure 1-2As shown, a filter screen 8 is installed inside the oil inlet pipe 7, and a sealing pipe cover 9 is installed on the top of the oil inlet pipe 7. When the lubricating oil enters the oil inlet pipe 7, impurities in the oil can be filtered through the filter screen 8. After use, the sealing pipe cover 9 can be opened to clean the impurities attached to the filter screen 8.

[0025] like Figure 1-3 As shown, guide grooves 13 are provided at the bottom of both ends of the oil filling pipe 4, and guide sliders 14 are slidably installed inside the guide grooves 13. An L-shaped connecting rod 15 is installed at the end of the guide slider 14 away from the guide groove 13, and the end of the L-shaped connecting rod 15 away from the guide slider 14 is connected to the anti-leakage baffle 6. The anti-leakage baffle 6 is guided by the L-shaped connecting rod 15 and the guide slider 14 so that the anti-leakage baffle 6 can only move in a straight line in the vertical direction.

[0026] Working principle:

[0027] When in use, the oil supply pump will draw the lubricating oil into the oil inlet pipe 7 through the oil supply pipe 10, and the impurities in the oil can be filtered through the filter 8. The filtered lubricating oil enters the oil filling pipe 4 through the oil inlet pipe 7;

[0028] The lubricating oil continues to flow into the oil filling pipe 4, causing the oil pressure inside the oil filling pipe 4 to increase. At this time, the anti-leakage baffle 6 is moved by the extrusion force, causing the anti-leakage baffle 6 to squeeze the return spring 5, and the anti-leakage baffle 6 no longer blocks the hedging guide pipe 3, so that the oil can be introduced into the semicircular buffer mixing chamber 11 through the hedging guide pipe 3;

[0029] When the oil enters the semicircular buffer mixing chamber 11 through the two sets of counter-flow guide pipes 3, since the two sets of counter-flow guide pipes 3 are installed opposite to each other, the oil can impact each other inside the semicircular buffer mixing chamber 11 when it is ejected through the two sets of counter-flow guide pipes 3, which not only reduces the impact force of the oil and plays a buffering role, so that the oil can flow out evenly, but also can fully mix the oil;

[0030] At the same time, after the oil enters the interior of the spiral tube 2 through the semicircular buffer mixing chamber 11, the spiral structure of the spiral tube 2 can stir the oil, causing the oil to impact each other, which can again achieve the effect of mixing the oil, so that the lubricating oil composition remains uniform and ensures the lubrication effect;

[0031] After the oil enters the core head 1 through the spiral tube 2, it is evenly sprayed out through the lubrication oil injection port 12 on the core head 1 to achieve a lubricating effect;

[0032] After lubrication is completed, the oil supply pump stops supplying oil. At this time, the oil pressure inside the oil filling pipe 4 is reduced, and the elastic action of the return spring 5 causes it to push the anti-leakage baffle 6 to move and reset, so that the anti-leakage baffle 6 blocks the counter-flow guide pipe 3 again, thereby preventing the oil from continuing to leak through the counter-flow guide pipe 3, thereby avoiding oil waste;

[0033] At the same time, the worker opens the sealing pipe cover 9 and cleans the impurities attached to the filter screen 8.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
