Description

Technical Field

[0001] This utility model relates to an oil collection device for a four-column hydraulic press. Background Technology

[0002] With the widespread application of hydraulic technology, four-column hydraulic presses, as a common pressure processing equipment, are widely used in metal forming, assembly, and plastic processing. During the operation of a hydraulic press, its column often requires lubrication to reduce friction and wear and extend the service life of the equipment. However, because the oil in the column is prone to dripping or leaking during the lubrication process, without effective collection measures, this oil will fall directly onto the bottom of the machine tool or the workshop floor, not only polluting the environment but also increasing safety hazards such as slipping on the ground.

[0003] Existing hydraulic presses typically rely on bottom trays or enclosure structures for initial oil collection. However, these structures are often bulky, complex to install, and loosely connected to the press body, leading to oil leaks, difficulties in disassembly and assembly, or disruptions to maintenance. Meanwhile, while some improved structures attempt to collect oil using annular flanges or added sealing components, they still suffer from significant shortcomings in terms of adaptability, ease of draining, and structural stability.

[0004] Therefore, there is an urgent need for an oil collection device that is compact, easy to install, convenient for oil drainage, and has good sealing performance. This device should effectively collect lubricating oil from the cylinder without affecting the normal operation and maintenance of the hydraulic press, thereby improving the cleanliness and safety of the equipment. To address these issues, designing an oil collection structure that can be directly installed at the cylinder nut, equipped with an oil drain port, and has a protective height is a key technical requirement that urgently needs to be solved by those skilled in the art. Utility model content:

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an oil collection device for a four-column hydraulic press.

[0006] An oil collection device for a four-column hydraulic press includes a chassis 4 and an oil baffle ring 3. The chassis 4 is a ring-shaped structure, and the oil baffle ring 3 is a thin rim with a certain height set along the edge of the chassis 4. The side of the oil baffle ring 3 is provided with an oil drain port 5. The chassis 4 is sleeved on the column of the hydraulic press and supported on a nut 2.

[0007] Furthermore, the chassis 4 is welded to the oil baffle ring 3.

[0008] Furthermore, the oil drain port 5 is equipped with a threaded connector to facilitate connection to the oil drain pipe.

[0009] Furthermore, the height of the oil baffle ring 3 is between 30 mm and 100 mm.

[0010] Furthermore, the gap between the inner diameter of the chassis 4 and the outer diameter of the column is within 2 millimeters.

[0011] Furthermore, the chassis 4 is made of corrosion-resistant metal material.

[0012] Beneficial effects: Compared with the prior art, this utility model only requires the oil collecting device 1 to be directly installed on the nut 2. This does not affect the operation of the machine tool, and at the same time, it can collect the lubricating oil in a unified manner. The operator only needs to clean the lubricating oil periodically through the oil drain port 5. Such a device is durable, easier to clean, makes the working environment cleaner and more hygienic, and also increases safety. Attached Figure Description

[0016] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0017] An oil collection device 1 for a four-column hydraulic press includes a chassis 4 and an oil baffle ring 3. The chassis 4 is a ring-shaped structure, and the oil baffle ring 3 is a thin rim with a certain height set along the edge of the chassis 4. The side of the oil baffle ring 3 is provided with an oil drain port 5. The chassis 4 is sleeved on the column of the hydraulic press and supported on a nut 2.

[0018] The core principle of this oil collection device 1 lies in the formation of an annular closed space around the hydraulic press column by the ring-mounted chassis 4, and the interception of hydraulic oil dripping due to column lubrication or leakage during operation by the oil-retaining ring 3 located on the edge of the chassis 4. The chassis 4 is supported on the hydraulic press nut 2, ensuring its stable positioning at an appropriate position below the column. Under the action of gravity, the hydraulic oil is collected by the oil-retaining ring 3 and gathers along its inner wall to the side with the oil drain port 5. The port can be connected to an oil drain pipe for convenient centralized discharge, preventing oil from spilling and polluting the surrounding environment.

[0019] This device has a simple structure, is easy to manufacture and install, and effectively collects residual oil flowing from the hydraulic press column, preventing oil from dripping onto the ground and causing pollution. Simultaneously, the oil drain port 5 located on the oil baffle ring 3 allows for centralized discharge of hydraulic oil, facilitating maintenance and reuse, and improving the cleanliness of equipment operation and the environmental level of the workplace. The device is tightly integrated with the hydraulic press structure, enhancing the safety and service life of the equipment.

[0020] In one possible implementation, the chassis 4 is welded to the oil baffle ring 3.

[0021] By welding the chassis 4 to the oil baffle ring 3, the two are integrated into a single structure, enhancing the overall sealing and structural strength of the oil collection device 1. This effectively prevents oil leakage caused by loosening or aging of the joints during hydraulic press operation. The welded structure also improves the rigidity and durability of the device, making it suitable for long-term stable operation in industrial environments.

[0022] This welding method can prevent oil leakage caused by improper assembly or loose threads during use, thereby improving the reliability and safety of equipment operation, while reducing maintenance frequency and extending service life.

[0023] In one possible implementation, the oil drain port 5 is provided with a threaded connector to facilitate connection to the oil drain line.

[0024] By incorporating a threaded connector at the oil drain port 5, the oil collection device 1 can be easily connected to an external oil drain line. This threaded structure ensures a tight connection, preventing oil leakage during draining and allowing for quick installation and disassembly, thus improving maintenance efficiency.

[0025] This structure improves the convenience and reliability of hydraulic oil discharge, is suitable for connecting different specifications of drain hoses or metal fittings, enhances the versatility and field adaptability of the device, and helps to achieve the standardization and modular configuration of the oil collection system.

[0026] In one possible implementation, the height of the oil baffle ring 3 is between 30 mm and 100 mm.

[0027] By designing the oil baffle ring 3 to a height between 30 mm and 100 mm, both oil collection capacity and structural compactness can be effectively balanced. This provides sufficient volume to collect dripping or splashing oil during operation without affecting the operation of the hydraulic press column. This height range also helps the oil to converge towards the drain port 5 under gravity, facilitating centralized discharge.

[0028] This height design ensures effective oil collection while reducing the risk of structural interference and improving the compatibility between the device and the hydraulic press column, making it suitable for various models and structural forms of hydraulic press systems.

[0029] In one possible implementation, the gap between the inner diameter of the chassis 4 and the outer diameter of the column is within 2 millimeters.

[0030] The gap between the inner diameter of the chassis 4 and the outer diameter of the column is controlled within 2 mm to ensure that the chassis 4 is tightly fitted onto the outside of the column, effectively preventing hydraulic oil from seeping out along the gap in the column and enhancing the sealing effect of the oil collection device 1. At the same time, this gap also facilitates the installation and disassembly of the chassis 4, avoiding interference that could affect the operation of the equipment.

[0031] This close-fitting design improves oil collection efficiency, prevents oil leakage from the junction of the chassis 4 and the column, enhances the cleanliness of the hydraulic system, and maintains the device's ease of installation and maintenance.

[0032] In one possible implementation, the chassis 4 is made of a corrosion-resistant metal material.

[0033] Choosing corrosion-resistant metal materials (such as stainless steel, galvanized steel, aluminum alloy, etc.) as the chassis 4 material can effectively resist the corrosion of hydraulic oil, lubricating oil, or environmental moisture, thereby maintaining the long-term stable operation of the device. This material selection also improves the structural strength and rigidity of chassis 4, ensuring that it does not deform or age during continuous operation of the hydraulic equipment.

[0034] The use of corrosion-resistant metal materials improves the service life and environmental adaptability of the oil collection device 1, reduces component damage and maintenance frequency caused by corrosion, lowers maintenance costs, and enhances the overall industrial applicability of the device.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
