[0029] Embodiment 1: A hydraulic guide mechanism comprises four guide columns 1, four oil tanks 4 and a lubrication assembly, wherein the four guide columns 1 are arranged in a rectangular array, the four oil tanks 4 are respectively located on the outside of the four guide columns 1, and the bottoms of the four oil tanks 4 are all provided with a fixing seat 5, and the outsides of the four guide columns 1 are all provided with a lubrication assembly;

[0030] The lubrication assembly includes an oil outlet block 2 and an oil receiving block 3. The oil outlet block 2 is welded up and down by two connecting columns 202 and a first shell 201. The outside of the oil receiving block 3 is a second shell 301, and a filter screen 302 is arranged inside. Four oil outlet blocks 2 and four oil receiving blocks 3 are arranged and are respectively installed on the outside of the guide column 1 near the top and the bottom.

[0031] In this embodiment, the first shell 201 is in the shape of a boss that is wide at the top and narrow at the bottom and hollowed out in the middle. A first connecting plate with an annular through hole is provided in the middle of the top surface of the first shell 201 , and the middle of the first connecting plate is plugged into the guide column 1 .

[0032] In this embodiment, a rotating plate 203 is disposed between the first connecting plate and the inner wall of the first shell 201 . The rotating plate 203 is hingedly connected to the first connecting plate. A first hand-held portion is also disposed on the top of the rotating plate 203 .

[0033] It should be noted that the first shell 201 is designed to be wide at the top and narrow at the bottom with a hollowed-out boss in the middle, which not only facilitates the distribution of the lubricating oil, but also reduces the resistance of the lubricating oil during the flow, thereby improving the lubrication efficiency. The annular through hole opened in the middle of the first connecting plate allows the guide column 1 to pass through easily, while providing a stable connection basis. The design of the rotating plate 203 being hinged to the first connecting plate makes it easy to adjust the angle of the rotating plate when necessary, thereby facilitating maintenance or inspection of the internal situation of the oil block 2. The provision of the first hand-held portion further enhances the convenience of operation.

[0034] In this embodiment, an oil inlet 204 is formed on the first housing 201 facing the oil tank 4 , and an oil guide ring 205 is disposed inside the first housing 201 and below the oil inlet 204 . The oil guide ring 205 is in the shape of a boss that is wider at the bottom and narrower at the top.

[0035] It should be noted that the boss-like design of the oil guide ring 205 , which is wider at the bottom and narrower at the top, combined with the overall structure of the oil outlet block 2 , effectively distributes the lubricating oil evenly on the surface of the guide column 1 , reducing the wear problem caused by uneven lubrication.

[0036] In this embodiment, the second shell 301 is also in the shape of a boss that is wide at the top and narrow at the bottom and hollowed out in the middle. The narrow end of the second shell 301 is plugged into the guide column 1 and fixed with bolts, and a sealing ring 303 is provided on the top of the plug-in point. The top surface of the second shell 301 is also provided with a second connecting plate with an annular through hole in the middle.

[0037] In this embodiment, the filter 302 is semicircular, and a plug is provided on the top thereof to be plugged into the second connecting plate. A second hand-held portion is provided on the top of the filter 302. An oil outlet 304 is provided on the second shell 301 facing the side of the oil tank 4. An inlet is provided on the side of the oil tank 4, and an outlet is provided on the top. A hydraulic pump 6 is also installed on the top of the outlet. Pipelines 7 are connected between the oil inlet 204 and the output end of the hydraulic pump 6, and between the oil outlet 304 and the inlet of the oil tank 4.

[0038] It should be noted that the semicircular ring design of the filter 302 is convenient for installation and disassembly, and the plug-in block on the top is plugged into the second connecting plate to ensure the firmness of the filter. At the same time, the filter 302 can effectively filter out impurities in the lubricating oil and protect the cleanliness of the lubrication system.

[0039] Embodiment 2: A CNC hydraulic press is equipped with a hydraulic guide mechanism, including a bottom plate 8, a damping plate 10, a push plate 11, a hydraulic telescopic column 12 and a top plate 13. The bottom plate 8 and the top plate 13 are bolted to the bottom and top of the four guide columns 1 respectively, the damping plate 10 is installed on the top of the bottom plate 8 near both sides, the hydraulic telescopic column 12 is installed in the middle of the top plate 13, and its output end is bolted downward to the push plate 11.

[0040] The push plate 11 is I-shaped, and its four end corners are respectively plugged with the four guide columns 1, the top of the connecting column 202 is bolted to the bottom of the top plate 13, and the sides of the four fixing seats 5 are welded to the outer side of the bottom plate 8.

[0041] It should be noted that the I-shaped design of the push plate 11 not only reduces the weight, but also enhances the stability of the plug-in connection with the guide column 1, thereby ensuring the smooth progress of the stamping operation.

[0042] In this embodiment, a stamping groove is opened on the top of the base plate 8, the middle section width of the I-shaped push plate 11 is equal to the width of the stamping groove, the shock absorbing plate 10 is installed on the top of the base plate 8 and is located on the outside of the stamping groove, and a spring group 9 is arranged between the shock absorbing plate 10 and the base plate 8.

[0043] It should be noted that the combined design of the shock absorbing plate 10 and the spring group 9 effectively absorbs the vibration and impact generated during the stamping process, protects the precision components of the equipment, and prolongs its service life.

[0044] Working principle:

[0045] Four guide columns 1 arranged in a rectangular array provide a stable and high-precision guide path for the CNC hydraulic press. The upper and lower ends of the guide columns 1 are respectively installed with oil outlet blocks 2 and oil receiving blocks 3 to form a complete lubrication system. When working, the hydraulic pump 6 transports the lubricating oil in the oil tank 4 to the oil inlet 204 of the oil outlet block 2 through the pipeline 7. The lubricating oil then flows through the oil guide ring 205. The lubricating oil is evenly distributed on the surface of the guide column 1 by utilizing its boss-shaped design of being wide at the bottom and narrow at the top, so as to achieve effective lubrication. During the movement of the guide column 1, excess lubricating oil and impurities are removed. The clean lubricating oil is collected in the second shell 301 of the oil collecting block 3 and filtered by the filter screen 302, and then flows back to the oil tank 4 through the oil outlet 304, thus completing the recycling of the lubricating oil. At the same time, the push plate 11 of the CNC hydraulic press performs stamping operation along the guide column 1 under the drive of the hydraulic telescopic column 12. The I-shaped design and the connection with the guide column 1 ensure the smoothness of the movement. The combination of the shock absorbing plate 10 and the spring group 9 effectively absorbs the vibration and impact generated during the stamping process, thus ensuring the stability of the equipment operation and the processing accuracy.

[0046] Beneficial effects:

[0047] The hydraulic guide mechanism and CNC hydraulic press provide stable and high-precision guiding action through four guide columns 1 distributed in a rectangular array, and then the oil outlet block 2 and the oil collecting block 3 are respectively installed on the top and bottom of the guide column 1, ensuring full-process lubrication and reducing wear. The first shell 201 of the oil outlet block 2 has a unique structure, combined with the oil inlet 204 and the oil guide ring 205, so that the lubricating oil can be evenly distributed on the surface of the guide column; the second shell 301 of the oil collecting block 3 has a built-in filter 302, which effectively filters impurities, maintains the cleanliness of the lubricating oil, and can also recycle the lubricating oil. In addition, the CNC hydraulic press integrates a bottom plate 8, a shock absorbing plate 10, a push plate 11, a hydraulic telescopic column 12 and a top plate 13. Through the combination of the shock absorbing plate 10 and the spring group 9, vibration and impact are effectively reduced, and the stability of equipment operation and the processing quality of the product are improved.
