[0002] A press is a general-purpose press with a delicate structure, which has the characteristics of wide application and high production efficiency. The press can be widely used in processes such as cutting, punching, blanking, bending, riveting and forming. Since each moving part of the press requires lubricating oil for lubrication during operation, lubricating oil is usually added to the connection parts of the moving parts at intervals. However, the lubricating oil often leaks out between the moving parts. In order to avoid the leaked lubricating oil interfering with the processing of the processed parts and for the purpose of saving lubricating oil, an oil receiving device is generally provided on the press. The publication number CN209189655U discloses an oil receiving device for a press, including a bottom mounting seat of the press, a smooth rod, an upper mounting seat of the press, a hydraulic cylinder, a hydraulic telescopic rod and a slider. The upper ends of the four corners of the bottom mounting seat of the press are provided with smooth rods, the upper ends of the smooth rods are provided with an upper mounting seat of the press, a hydraulic cylinder is mounted on the upper end of the upper mounting seat of the press, a hydraulic telescopic rod is mounted at the bottom end of the hydraulic cylinder, a slider is mounted at the bottom end of the hydraulic telescopic rod, a fixed frame is mounted outside the slider, the two sides of the slider are slidably arranged on the smooth rod through the fixed frame, an oil receiving tray is sleeved outside the slider, a plurality of first oil leakage holes are opened on the bottom surface of the oil receiving tray, and a first oil receiving groove is opened at the upper end of the bottom mounting seat of the press. This utility model receives oil more comprehensively, and can filter the collected lubricating oil to filter out slag, and it is not easy to cause mechanical wear when reused.

By setting structures such as long rods 6, fixing pieces 7, limiting holes 8, connecting blocks 9, mounting holes 10, springs 11 and limiting blocks 12, by simultaneously pressing the four groups of limiting blocks 12, the limiting blocks 12 are made to squeeze the springs 11 and retract into the mounting holes 10. After retracting, the limiting blocks 12 will move away from the limiting holes 8. After moving away, the oil receiving tray 13 can be slid out from the outer wall of the hydraulic telescopic rod 5 for cleaning. After cleaning, the two connecting blocks 9 are aligned with the inside of the fixing piece 7. After alignment, the four groups of limiting blocks 12 are simultaneously pressed to make the limiting blocks 12 retract into the mounting holes 10. After retracting, the connecting block 9 is pushed upward. After pushing a certain distance, the spring 11 will automatically pop the limiting block 12 into the limiting hole 8, thereby fixedly connecting the connecting block 9 and the oil receiving tray 13. This structure can quickly disassemble and assemble the oil receiving tray 13, thereby facilitating the operator to clean the oil receiving tray 13, and effectively avoiding that the dirty oil receiving tray 13 will affect the secondary use of the lubricating oil.

[0025] Embodiment Two

[0026] Please refer to Figure 4A fixing ring 14 is fixedly installed on the inner wall of the oil receiving pan 13, and an annular frame 15 is installed on the top of the fixing ring 14. An oil filter net 16 is fixedly installed inside the annular frame 15. The oil filter net 16 facilitates filtering the lubricating oil flowing into the oil receiving pan 13. A pull rod 17 is fixedly installed on the top of the annular frame 15. By pulling the pull rod 17 upward, the annular frame 15 and the oil filter net 16 can be driven to slide upward on the inner wall of the oil receiving pan 13, thereby making it convenient to remove the oil filter net 16 for cleaning. The annular frame 15 is slidably connected to the oil receiving pan 13, and the disassembly and assembly efficiency of the annular frame 15 is improved through the sliding connection. By providing structures such as a fixing ring 14, an annular frame 15, an oil filter net 16 and a pull rod 17, the lubricating oil flowing into the oil receiving pan 13 can be filtered through the oil filter net 16. When there are many impurities on the oil filter net 16, the pull rod 17 can be pulled upward to drive the annular frame 15 and the oil filter net 16 to slide upward on the inner wall of the oil receiving pan 13. After sliding a certain distance, they can be taken out and cleaned. This structure improves the filtering effect of the lubricating oil and facilitates the secondary use of the lubricating oil by the operating personnel.

[0027] Working principle: when in use, first start the hydraulic cylinder 4, and drive the hydraulic telescopic rod 5 to slide downward on the inner wall of the oil receiving pan 13 through the hydraulic cylinder 4. Lubricating oil will seep out of the hydraulic telescopic rod 5 during the movement, and the seeped lubricating oil will flow into the oil receiving pan 13. When there is too much lubricating oil in the oil receiving pan 13, the four groups of limit blocks 12 can be pressed at the same time to make the limit blocks 12 squeeze the spring 11 and retract into the mounting hole 10. After retraction, the limit blocks 12 will move away from the limit holes 8. After moving away, the oil receiving pan 13 can be slid out from the outer wall of the hydraulic telescopic rod 5 for cleaning. After cleaning, align the two groups of connecting blocks 9 with the inner side of the fixing plate 7. After alignment, press the four groups of limit blocks 12 at the same time to make the limit blocks 12 retract into the mounting hole 10. After retraction, push the connecting block 9 upward again. After pushing a certain distance, the spring 11 will automatically bounce the limit block 12 into the limit hole 8, thereby fixing the connecting block 9 and the oil receiving pan 13. When the lubricating oil flows into the oil receiving pan 13, the oil filter 16 will filter the lubricating oil. When there are many impurities on the oil filter 16, the pull rod 17 can be pulled upward to drive the annular frame 15 and the oil filter 16 to slide upward on the inner wall of the oil receiving pan 13. After sliding a certain distance, they can be taken out and cleaned.
