Technical Field

[0001] The utility model relates to the technical field of bearing lubrication equipment, in particular to a lubrication device between copper bushes and shafts of a forging machine. Background Art

[0002] A forging machine is a mechanical equipment used for metal processing and forming. It is often used in processing processes such as bending, folding, stretching, compressing, and cutting of plates, bars, pipes, etc. The copper tile shaft inside the forging machine supports the forging machine. When the copper tile shaft works for a long time, a grease gun needs to be used to inject grease into the inside for lubrication. The existing grease gun needs to be filled with grease before use. After the grease is added, air will be generated between the piston and the grease inside the grease gun. When the air is added to the copper tile shaft, the grease output will be unstable, which will lead to a reduction in the lubrication effect of the copper tile shaft. Utility Model Content

[0021] 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.

[0022] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A lubrication device between copper bearing shafts of a forging machine includes: a storage cylinder 1, a nozzle 2 and an extrusion mechanism 3. The storage cylinder 1 can store butter. A valve is provided on the outside of the nozzle 2 to discharge the butter. The extrusion mechanism 3 can squeeze the butter and discharge it through the nozzle 2. The nozzle 2 is connected to the bottom of the storage cylinder 1. Telescopic rods 11 are evenly distributed on the outside of the storage cylinder 1, and the bottom of the telescopic rods 11 is equipped with support feet 12.

[0023] The storage cylinder 1 includes a first cylinder, a second cylinder and a third cylinder. The first cylinder and the second cylinder are connected by a second threaded connection 14. The top of the first cylinder is connected to the extrusion mechanism 3 through a connecting arm, and the first cylinder and the threaded rod 32 are connected by a bearing. The outside of the second cylinder is connected to the third cylinder through a first threaded connection 13. The third cylinder is connected to the nozzle 2. The first cylinder, the second cylinder and the third cylinder are disassembled, which will facilitate the filling of butter and cleaning inside the storage cylinder 1. The connection between the first cylinder, the second cylinder and the third cylinder is provided with threads, and the first cylinder, the second cylinder and the third cylinder are connected by the second threaded connection 14 and the first threaded connection 13 with the matching threads.

[0024] See also Figure 3 and Figure 4 The extrusion mechanism 3 includes a motor 31, which can provide drive. The output end of the motor 31 is connected to a threaded rod 32, which can drive the nut 33 to descend. The external thread of the threaded rod 32 is connected to the nut 33, which can drive the piston 34 to descend. The shape of the piston 34 is elliptical and adapts to the interior of the storage cylinder 1 to prevent the piston 34 from rotating when it moves.

[0025] The outside of the nut 33 is sleeved with a piston 34, which can squeeze the lubricating oil. Slide grooves 36 are evenly distributed on the top of the piston 34, and the slide grooves 36 are slidably connected to the block 43. A spring 44 is connected between the block 43 and the slide groove 36. The slide groove 36 can guide the block 43, and the spring 44 can drive the block 43 to return to its position after the movement is completed. Collection boxes 35 are evenly distributed on the top of the piston 34.

[0026] The top of the collection box 35 is equipped with a baffle 37, which can collect the discharged butter. The baffle 37 can facilitate the block 43 to push the butter into the interior of the collection box 35. The top of the piston 34 is evenly distributed with vertical grooves 39, which are adapted to the block 43. The vertical grooves 39 can discharge a small amount of butter and air, and the block 43 can close the vertical grooves 39. The bottom of the threaded rod 32 is connected to a hexagonal block 38 through a seat bearing. The hexagonal block 38 is embedded in the inner bottom of the storage tube 1. The hexagonal block 38 can be stuck in the inner bottom of the storage tube 1, and then support the threaded rod 32.

[0027] The outside of the storage cylinder 1 is evenly distributed with a closing mechanism 4, which includes a hollow column 41. The hollow column 41 can accommodate the trapezoidal block 42 and drive the trapezoidal block 42 to move through the inclined surface of the inner bottom. The hollow column 41 is connected to the storage cylinder 1. The interior of the hollow column 41 is slidably connected to the trapezoidal block 42, and the outside of the trapezoidal block 42 is connected to a stopper 43. The stopper 43 can close the vertical groove 39 and can push the butter to move.

[0028] This solution first opens the storage cylinder 1 by rotating the second cylinder, adds butter to the inside of the third cylinder, and then closes the storage cylinder 1. The storage cylinder 1 is fixed to the top of the forging machine through the telescopic rod 11 and the support leg 12, and is connected to the nozzle 2 and the oil tank inside the copper tile shaft through the pipeline, or the end of the pipeline connected to the copper tile shaft is directly disconnected and the butter is sprayed directly on the inner shaft of the copper tile shaft. The nozzle 2 is closed through the valve, the motor 31 is started to drive the threaded rod 32 to rotate, and then the piston 34 is driven down through the nut 33. The piston 34 will squeeze the top of the butter when it descends. The air on the top of the butter is discharged through the vertical groove 39, and part of the butter is also discharged through the vertical groove 39. When the piston 34 moves to the bottom of the hollow column 41, the trapezoidal block 42 contacts the bottom of the inner side of the hollow column 41 and is then driven by the friction, and at the same time drives the stopper 43 to move, closing the vertical groove 39, and the butter on the top of the piston 34 is pushed into the interior of the collection box 35 for collection through the guidance of the baffle 37. After the lubrication of the copper shoe shaft is completed, the staff can open the ground cylinder, pull the collection box 35 out of the interior of the piston 34, and recycle the butter inside.

[0029] Before the copper bushing shaft is lubricated with butter, the air on the top of the butter is automatically discharged through the added closing mechanism 4 and the squeezing mechanism 3 to prevent the air from causing the butter to be discharged unsmoothly and unsteadily, thereby reducing the lubricating effect of the butter on the copper bushing shaft. At the same time, the discharged butter can also be recycled and collected, thereby facilitating the reduction of butter waste, reducing economic losses and improving overall practicality.
