Description

Technical Field

[0001] This invention relates to the field of mechanical equipment lubrication technology, specifically a corrugated plate type lubricating oil tank for a radial forging machine. Background Technology

[0002] As a heavy-duty, precision, and high-load hot forging equipment, the radial forging mill's main unit (primarily composed of a gearbox and forging box) operates at high speeds, with internal parts rotating at frequencies of hundreds or thousands of times per minute. This not only requires sufficient lubricating oil to ensure adequate lubrication of the moving parts but also necessitates the timely removal of the large amount of heat generated by friction through the lubricating oil. Therefore, radial forging mills generally employ a centralized thin oil lubrication system, equipped with a large dedicated lubrication station. The design standards of this oil tank system far exceed those of ordinary equipment, primarily reflected in: extremely high oil cleanliness, accurate oil temperature control, continuous operational reliability, and convenient maintenance, collectively forming the key foundation for ensuring the long-term stability and precision of the equipment. Traditional oil tanks often have relatively simple or fixed internal structures, making it difficult to achieve efficient bubble escape, impurity sedimentation, and flow stabilization. Furthermore, the complex internal components are difficult to clean, making it difficult to meet all the comprehensive requirements of the radial forging mill lubrication system. Summary of the Invention

[0003] The purpose of this invention is to provide a corrugated plate type lubricating oil tank for radial forging machines. This corrugated plate type lubricating oil tank for radial forging machines has the characteristics of reasonable structure, integrated function and convenient maintenance. It achieves efficient purification and stable flow of oil through modular and detachable corrugated plate device, and greatly improves the convenience of maintenance, thereby improving the overall reliability of the lubrication system.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a corrugated plate lubricating oil tank for a radial forging machine, comprising an oil tank body, wherein a first oil suction port, a second oil suction port, and an oil return port are provided on the side wall of the oil tank body, and an integrally detachable corrugated plate device is provided inside the oil tank body, the corrugated plate device being installed inside the oil tank body by a fixed bracket, and dividing the inner cavity of the oil tank into an oil return zone and an oil suction zone that are interconnected; the corrugated plate device includes a mounting frame, within which multiple layers of corrugated plates are arranged vertically from bottom to top, the corrugated plates being fixed to the mounting frame by positioning blocks, and honeycomb plates being provided on both sides of the mounting frame; inclined oil suction guide plates and oil return guide plates are provided on the inner sides of the first oil suction port, the second oil suction port, and the oil return port; a heating module is provided at the bottom of the oil tank body, located below the corrugated plate device, an air filter is installed at the top, and a level gauge and a temperature sensor extending below the liquid surface in the oil suction zone are installed on the side wall.

[0005] Preferably, the fixed bracket is an internal positioning device for the fuel tank, which has a waist-shaped hole and is used to connect and fix the corrugated plate device to the fuel tank body with screws.

[0006] Preferably, the mounting frame is a rectangular frame, and the corrugated plates are arranged at an inclined angle within the mounting frame.

[0007] Preferably, the guide baffle disposed inside the oil return port is an oil return guide plate, and the guide baffle disposed inside the first oil suction port and the second oil suction port is an oil suction guide plate.

[0008] Preferably, the top of the fuel tank body is provided with a detachable fuel tank top plate, and the fuel tank top plate has a mounting hole and an air filter is installed thereon.

[0009] Preferably, the top of the oil tank body is also provided with an openable observation cover, and the side is provided with a manhole cover.

[0010] Preferably, the heating module is located below the corrugated plate device, and the area below the corrugated plate device constitutes the heating zone.

[0011] Preferably, the mounting frame of the corrugated plate device is provided with a hoisting structure.

[0012] Preferably, the corrugated plate device is detachably connected to the fuel tank body, so that the entire corrugated plate device can be removed from the fuel tank body as a whole, and after the corrugated plate device is lifted out of the fuel tank, the positioning block can be removed to take out all the corrugated plates.

[0013] Preferably, the surface of the corrugated sheet is welded with rectangular grid strips, and the material of the corrugated sheet is preferably stainless steel.

[0014] The working principle of this invention is as follows: Return oil containing air bubbles and impurities enters the return oil zone of the oil tank through the return oil port. The return oil guide plate, which is inclined inside the return oil port, guides the high-speed return oil to the inner wall of the tank, allowing it to slide smoothly down the wall and avoiding liquid impact and air entrainment.

[0015] The oil in the return zone first flows through the honeycomb plates on both sides of the corrugated plate device, where the honeycomb plates initially stabilize the flow and break up large air bubbles. The oil then enters the interior of the corrugated plate device, flowing slowly between multiple layers of inclined corrugated plates. The corrugated structure of the corrugated plates lengthens the path of the oil from the return zone to the suction zone, increasing the oil's residence time. During this process, small air bubbles rise and escape, while impurities such as metal particles settle, achieving oil purification. The purified and stabilized oil flows smoothly into the suction zone. The clean oil in the suction zone is evenly distributed into the second suction port via the suction guide plate for circulation in the lubrication system. The circular perforations on the suction guide plate prevent oil vortices and maintain flow stability. A heating module located below the corrugated plate device heats the oil in low-temperature environments. A temperature sensor monitors the oil temperature in real time, an air filter balances the internal and external air pressure and filters the intake air, and a level gauge monitors the oil level. During maintenance, loosen the screws of the fixing bracket, lift the entire corrugated board assembly out of the box, remove the positioning block, and each corrugated board can be taken out individually for cleaning, achieving in-depth maintenance.

[0016] The beneficial effects of this invention are as follows: (1) The present invention divides the oil tank into sections using a modular corrugated plate device (a combination of honeycomb plates and multi-layer inclined corrugated plates). The oil in the return oil zone first diffuses, stabilizes, and breaks up large air bubbles through the honeycomb plates, and then slowly passes through the multi-layer corrugated plates. This combined structure extends the path of the oil from the return oil zone to the suction oil zone, providing sufficient time and space for air bubbles to escape and impurities to settle, thus realizing the comprehensive functions of defoaming, sedimentation filtration, and flow stabilization, and greatly improving the cleanliness of the oil.

[0017] (2) The present invention adopts an overall modular design and can be quickly lifted out of the oil tank by means of an adjustable fixed bracket. At the same time, the corrugated plates inside the corrugated plate device are fixed by positioning blocks and can be completely disassembled, which facilitates thorough cleaning of each corrugated plate and honeycomb plate. This solves the technical problem of complex internal structure and difficult cleaning of traditional oil tanks, and facilitates deep cleaning, inspection and maintenance, significantly reducing downtime and maintenance costs.

[0018] (3) The inclined guide baffles installed on the inner side of the inlet and outlet oil ports in this invention can effectively suppress the direct impact of large flow of oil on the liquid surface in the tank and the air entrainment effect, and maintain the stability of the flow state in the tank. Combined with the heating module located at the bottom of the corrugated plate device for precise control of oil temperature, it ensures that the lubrication system can operate stably and reliably under various working conditions, especially during low temperature start-up and continuous high load operation, and meets the long cycle and high precision working requirements of the radial forging machine.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown in the figure, an embodiment of the present invention provides a corrugated plate type lubricating oil tank for a radial forging machine, the main body of which is a rectangular oil tank body 1. A removable oil tank top plate 3 is provided on the top of the oil tank body 1, and a high-efficiency air filter 4 is installed on the top plate 3. An openable observation cover 2 is also provided for daily observation of the tank's internal condition. An oil return port 5, a first oil suction port 10, and a second oil suction port 11 are respectively provided on the side walls of the oil tank body 1. A magnetic level gauge 6 with high and low liquid level alarm functions and a temperature sensor 8 for real-time monitoring of oil temperature are also installed on the side walls. The detection parts of the level gauge 6 and the temperature sensor 8 extend below the liquid surface in the oil suction area 101. A manhole cover 12 is also provided on the side of the oil tank body 1 to facilitate personnel entering the tank for inspection or maintenance.

[0022] The interior of the fuel tank body 1 is divided into a left-side oil suction area 101 and a right-side oil return area 102 by a detachable corrugated plate device 7. The space between the corrugated plate device 7 and the bottom of the tank forms a heating area 103. The corrugated plate device 7 is fixed inside the tank body 1 by a fixing bracket 13. The fixing bracket 13 is provided with an oblong hole, and the connection and positioning between the corrugated plate device 7 and the fuel tank body 1 are achieved by screws. This oblong hole design allows for fine-tuning during installation to ensure accurate positioning of the corrugated plate device 7, and the entire device can be lifted out simply by loosening the screws during disassembly.

[0023] like Figure 4 and Figure 5As shown, the corrugated plate device 7 includes a rigid rectangular mounting frame 702. The mounting frame 702 has lifting holes for easy hoisting. Multiple mounting positions are formed within the mounting frame 702 by partitions, allowing multiple layers of corrugated plates 701 to be installed sequentially from bottom to top at a certain angle. Each layer of corrugated plate 701 is fixed within the mounting frame 702 by positioning blocks 703 to prevent movement. Honeycomb plates 704 are screwed onto both sides of the mounting frame 702. The honeycomb plates 704 provide initial flow stabilization and break up larger air bubbles in the oil from the return oil zone 102. The oil then enters the corrugated plate device 7. As it flows through the multiple layers of inclined corrugated plates 701, their corrugated structure effectively extends the oil's flow path and increases its residence time within the device. During this process, small air bubbles in the oil have sufficient time to rise and escape, while tiny metal particles and other impurities settle under gravity. The treated clean oil flows smoothly into the oil suction zone 101. The tilt angle of the corrugated plate 701 helps guide the bubbles to rise along the plate surface and exit the device.

[0024] At the bottom of the oil tank body 1, specifically in the heating zone 103 directly below the corrugated plate device 7, a heating module 9 consisting of electric heating rods is installed. The heating module 9 is used to rapidly raise and maintain the oil temperature within the optimal operating temperature range when the equipment is started at a low temperature or the ambient temperature is low, thus ensuring lubrication performance.

[0025] This invention creatively incorporates flow control measures at the oil inlet and outlet. An inclined return oil guide plate 15 is welded to the inner side of the return oil port 5. This baffle guides the high-speed oil flow returning from the lubrication system to the inner wall of the oil tank 1, allowing it to flow smoothly downwards along the wall, effectively preventing violent fluctuations, splashing, and air being drawn into the oil caused by direct impact of the oil flow on the liquid surface. An oil suction guide plate 14 is welded to the inner side of the first oil suction port 10 and the second oil suction port 11. This oil suction guide plate 14 has multiple evenly distributed circular holes, allowing the oil in the oil suction zone 101 to pass evenly and smoothly through the guide plate into the second oil suction port 11, preventing the generation of oil suction vortices and further stabilizing the flow within the tank.

[0026] When cleaning and maintenance of the fuel tank is required, the maintenance process is extremely convenient. First, open the removable top plate 3 of the fuel tank, and then loosen the screws on the internal fixing bracket 13. Using the lifting holes on the mounting frame 702, the entire corrugated plate device 7 can be lifted out of the fuel tank body 1 as a whole module. After placing the corrugated plate device 7 in the maintenance area, the positioning blocks 703 used to fix the corrugated plates 701 can be further removed, allowing each corrugated plate 701 to be removed individually. At the same time, the honeycomb panels 704 on both sides can also be removed by unscrewing the screws. In this way, all components of the corrugated plate device 7 can be completely disassembled, facilitating a thorough cleaning of each corrugated plate 701, honeycomb panel 704, and mounting frame 702, removing attached sludge and impurities, and solving the problem of many dead corners in cleaning traditional welded or fixed internal structures.

[0027] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, based on the technical teachings provided by the present invention and as common knowledge in the mechanical field, other equivalent modifications and improvements can be made, and these should also be considered within the scope of protection of the present invention.
