Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown, the heavy-duty shearing machine's upper blade lubrication structure of this utility model includes a drive mechanism 3, an oil tank 5, and an oiling plate 2 disposed between the pressure plate 13 of the shearing machine and the outer side of the upper shear blade 12 for lubricating the upper shear blade 12. The length and width of the oiling plate 2 are generally set according to the length and width of the upper shear blade 12. The side of the oiling plate 2 facing the upper shear blade 12 is provided with a compressible oil-absorbing material layer 21. The oiling plate 2 is provided with multiple hoses 4 arranged at intervals along the length direction of the oil-absorbing material layer 21, one end of which is connected to the oil tank, and the other end is connected to the oil-absorbing material layer 21 to supply oil to the oil-absorbing material layer 21. The drive mechanism 3 is mounted on the pressure plate 13 of the shearing machine. The drive mechanism 3 is connected to the oiling plate 2 to support the oiling plate 2 and drive the oiling plate 2 to move along the direction close to or away from the outer side of the upper shear blade 12, thereby applying oil to the outer side of the upper shear blade 12 or moving away from the upper shear blade 12.

[0022] The drive mechanism 3 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc. Figure 3 In the middle, the drive mechanism 3 is a hydraulic cylinder.

[0023] The oil reservoir 5 is typically mounted on the shearing machine frame. When the oil reservoir 5 is positioned higher than the oiling plate 2, the lubricating oil can automatically flow through the hose into the oil-absorbing material layer 21 using gravity. When the oil reservoir is positioned lower than the oiling plate 2, it is understood that an oil pump connected to the hose 4 should be installed on the oil reservoir 5 to pump the lubricating oil from the reservoir 5 into the hose 4 in order to supply oil to the oil-absorbing material layer 21. A small-diameter pipe of 2–5 mm is generally preferred for the hose 4.

[0024] The heavy-duty shearing machine's upper blade lubrication structure of this invention introduces lubricating oil from the oil reservoir 5 into the oil-absorbing material layer 21 via a hose, allowing the oil-absorbing material layer 21 to absorb oil. When lubrication of the upper shearing blade is required, the drive mechanism 3 drives the oiling plate 2 to move along the outer side of the upper shearing blade 12, causing the oil-absorbing material layer 21 of the oiling plate 2 to adhere to the outer side of the upper shearing blade 12 and be compressed by a certain amount, thereby squeezing out the lubricating oil in the oil-absorbing material layer 21 and allowing some lubricating oil molecules to adhere to the outer surface of the upper shearing blade, thus achieving the purpose of lubrication. Therefore, this invention does not generate oil mist during the lubrication process, has minimal pollution to the surrounding environment, and is also relatively economical in terms of lubricating oil. The compression amount of the oil-absorbing material layer 21 during the lubrication process is set as needed to ensure lubrication of the upper shearing blade. After the upper shear blade is lubricated, the drive mechanism 3 drives the oiling plate 2 to move away from the outer side of the upper shear blade 12, so that the oiling plate 2 leaves the upper shear blade 12. At this time, the oil-absorbing material layer 21 recovers its deformation and can absorb oil for lubrication again. Since the drive mechanism 3 is installed on the shearing machine pressure plate 13, and the oiling plate 2 is connected to and supported by the drive mechanism 3, the pressure plate 13 will float upward due to the action of the sheet metal during the closing of the upper and lower shear blades. Therefore, during the shearing process, the pressure plate 13 will drive the drive mechanism 3 and the oiling plate 2 to move upward together, so that the oiling plate 2 will move away from the upper shear blade 12 to avoid affecting the shearing of the sheet metal, making the shearing machine more convenient to use.

[0025] The hoses 4 are spaced apart along the length of the oil-absorbing material layer 21, which makes the lubricating oil content more uniform throughout the oil-absorbing material layer 21, and can better ensure the lubrication effect on the upper shear blade. The specific spacing between the hoses can be determined experimentally based on the hose diameter, actual flow rate, etc.

[0026] The oil-absorbing material layer can be made of sponge, cotton cloth, tar paper, etc. In this embodiment of the present invention, the oil-absorbing material layer 21 is a sponge.

[0027] like Figure 1 and Figure 3 As shown, the lower end of the oiling plate 2 is provided with an oil receiving groove 22. The oil receiving groove 22 can be used to collect the lubricating oil that overflows from the oil-absorbing material layer 21 and is squeezed out from the oil-absorbing material layer 21 after the oiling and lubrication process.

[0028] To control the compression deformation of the oil-absorbing material layer 21 and prevent it from being crushed, such as Figure 2 As shown, the oiling plate 2 is provided with limiting posts 23 for limiting the amount of compression deformation of the oil-absorbing material layer 21. In addition, the limiting posts 23 can control the amount of compression deformation of the oil-absorbing material layer 21, and also facilitate the control of the amount of lubricating oil used in each lubrication process.

[0029] The oiling plate 2 and the drive mechanism 3 can be rigidly connected. For example...Figure 3 and Figure 4 As shown, the oiling plate 2 is connected to the drive mechanism 3 in the following way: a guide cylinder 6 is installed on the oiling plate 2 along a direction perpendicular to the outer side of the upper shear blade 12. One end of the drive mechanism 3 is inserted into the guide cylinder 6 and slidably connected to the guide cylinder 6. A compressible relief spring 7 is provided inside the guide cylinder 6, with one end connected to the insertion end of the drive mechanism 3 and the other end connected to the oiling plate 2. The guide cylinder 6 can be fixed to the oiling plate 2 by welding or bolt connection. Since the position of the pressure plate 13 of the shearing machine will have a certain offset problem during use, and the position repeatability of the pressure plate 13 is poor, the drive mechanism 3 can compress the relief spring 7 to make the relief spring 7 move aside. Therefore, the theoretical maximum required stroke of the drive mechanism 3 can be set as its working stroke to ensure that when the pressure plate 13 is offset away from the outer side of the upper shear blade by the maximum distance, the drive mechanism 3 can also keep the pressure plate 13 attached to the outer side of the upper shear blade to ensure the lubrication effect. When the pressure plate 13 is not at the maximum distance position away from the outer side of the upper shear blade, the drive mechanism 3 can compress the relief spring 7 to make it move away, thereby avoiding deformation and damage to the pressure plate 13, drive mechanism 3, etc.

[0030] When the drive mechanism 3 uses hydraulic cylinders, pneumatic cylinders, etc., in order to facilitate the control of its movement, it is generally necessary to use sensor technology to sense the position of the lower blade holder 14 or the lower shear blade of the shearing machine, and then control the drive mechanism 3 to perform the oiling or moving away from the upper shear blade action according to the position of the lower blade holder 14 or the lower shear blade. This results in a high cost for the drive mechanism 3. Figure 5 As shown, in one embodiment of this utility model, the driving mechanism 3 includes a connecting rod 32 and a push rod 31, one end of which is connected to the pressure plate 13 to drive the oiling plate 2 to move along the direction of approaching or away from the outer side of the upper shear blade 12. The push rod 31 is slidably connected to the pressure plate 13 in a direction perpendicular to the outer side of the upper shear blade 12. One end of the connecting rod 32 is hinged to the lower blade holder 14 of the shearing machine, and the other end is hinged to the connecting rod 32. During the upward movement of the lower blade holder 14, the push rod 31 is pushed to move away from the outer side of the upper shear blade 12, thereby moving the oiling plate 2 away from the upper shear blade. During the downward movement, the push rod 31 is pushed to move closer to the outer side of the upper shear blade 12, thereby making the oiling plate 2 adhere to the upper shear blade and achieve oiling and lubrication of the upper shear blade. The above structure drives the pressure plate 13 through a mechanical structure connected to the lower blade holder 14, eliminating the need for sensors and controllers. The driving mechanism 3 has low cost and better reliability. To influence the loading and unloading of sheet metal, connecting rod 32 and connecting rod 32 are generally arranged on both sides of the shearing machine.
