[0032] Example 1

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a lubrication mechanism of a hydraulic press, a base 1, a die 2 is fixedly connected to the top of the base 1, columns 3 are fixedly connected at the four corners of the top of the base 1, supporting a cylinder device 4 and a hydraulic plate 5, providing a track for vertical movement, cylinder devices 4 are installed on the tops of the four columns 3, driving the hydraulic plate 5 to move up and down, the surfaces of the four columns 3 are slidably connected to the hydraulic plates 5, and the hydraulic plates 5 are transmission-connected to the output ends of the cylinder devices 4;

[0034] The locking member 6 and the adjusting member 7 are arranged on the surface of the cylinder device 4. A movable member 8 is arranged on the top of the hydraulic plate 5. The movable member 8 includes two horizontal plates 81, four circular rings 82 and two through holes 83. The surface of the circular ring 82 is provided with a lubricating member 9.

[0035] In an embodiment of the present application, four circular rings 82 are respectively fixedly connected to both ends of two cross plates 81. The four circular rings 82 are sleeved on the surfaces of four columns 3. Two through holes 83 are respectively opened in the middle of the surfaces of the two cross plates 81. The lubricating member 9 includes an oil filling groove 91 opened at the top end of the circular ring 82. The oil filling groove 91 is designed with a wider upper part and a narrower lower part. This design prevents the cover 97 from falling to the low point inside the oil filling groove 91 and plays a role in covering the oil filling groove 91. An oil storage groove 92 is opened inside the circular ring 82 for storing lubricating oil. The inner cavities of the oil filling groove 91 and the oil storage groove 92 are connected. A cover 97 is placed inside the inner cavity of the oil filling groove 91. Side holes 93 are opened on the outer side wall of the circular ring 82. A transparent plate 94 is fixedly connected to the inner wall of the side hole 93, which is convenient for the staff to observe the capacity of the lubricating oil inside the circular ring 82. An oil absorbing cotton 95 and an oil wiping cotton 96 are arranged inside the circular ring 82. The lubricating oil is immersed into the oil wiping cotton 96 through the oil absorbing cotton 95, and the lubricating oil is smeared on the surface of the column 3 through the oil wiping cotton 96. One side part of the oil absorbing cotton 95 fixedly penetrates through the inner side wall of the circular ring 82 to the inner cavity of the oil storage groove 92, and the oil wiping cotton 96 is fixedly connected to the oil absorbing cotton 95.

[0036] In an embodiment of the present application, the locking member 6 includes limiting plates 61 respectively fixed on both side walls of the oil cylinder device 4. The limiting plates 61 are designed in a T shape. This design not only plays a role in limiting the moving plate 62 but also plays a role in preventing detachment. A moving plate 62 is movably sleeved on the surface of the limiting plate 61. The adjusting member 7 includes a supporting plate 71 fixed on the top end of the oil cylinder device 4. A threaded cylinder 72 is rotatably connected to the top of the surface of the supporting plate 71. Two opposite threads are distributed on both sides of the inner cavity of the threaded cylinder 72, so that when it rotates, two threaded rods 73 move relatively or away from each other. Both sides of the inner cavity of the threaded cylinder 72 are threadedly connected with threaded rods 73. One ends of the two threaded rods 73 are respectively rotatably connected to the surfaces of the two moving plates 62. One ends of the two moving plates 62 respectively movably penetrate through the inner cavities of the two through holes 83. The moving plate 62 plays a role in limiting the cross plate 81 through the through hole 83. It also includes a connecting member 10 placed between the circular ring 82 and the hydraulic plate 5. The connecting member 10 includes four magnetic rings I 101 and four magnetic rings II 102. Through the magnetic rings I 101 and the magnetic rings II 102, after the cross plate 81 is released from the limit, a part of the movable member 8 is connected to the hydraulic plate 5. The four magnetic rings I 101 are respectively fixed at the bottom ends of the four circular rings 82. The four magnetic rings II 102 are sleeved on the surfaces of the four columns 3 and are fixedly connected to the top end of the hydraulic plate 5. The magnetic ring I 101 is magnetically connected to the magnetic ring II 102.

[0037] The usage process of a lubricating mechanism for a hydraulic press provided by the present utility model is as follows: First, when it is necessary to supply oil to the surfaces of the four columns 3, the staff rotates the threaded cylinder 72 by hand, and the two threaded rods 73 will drive the two moving plates 62 to move relative to each other under the limiting action of the limiting plate 61 until one end of the two moving plates 62 disengages from the inner cavity of the through hole 83, releasing the limitation on the two cross plates 81. Subsequently, under the action of gravity, the first magnetic ring 101 and the second magnetic ring 102, the cross plate 81 drives the four rings 82 to move downward until the first magnetic ring 101 is magnetically connected to the second magnetic ring 102, and then it moves along with the movement of the hydraulic plate 5. During the movement, the lubricating oil in the oil storage tank 92 soaks into the oil wiping cotton 96 through the oil absorbing cotton 95, and the oil wiping cotton 96 will apply lubricating oil to the surface of the column 3 as it moves along with the movement of the hydraulic plate 5. When the staff observes through the transparent plate 94 that the lubricating oil in the oil storage tank 92 is in a large amount, the cover 97 can be lifted out, and lubricating oil can be injected into the oil storage tank 92 through the oil filling groove 91.
