Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment equipment technology, and in particular to a through-type ultrasonic oil immersion line equipment. Background Technology

[0002] In industrial production, oil immersion is a common surface treatment process for metal workpieces, used for rust prevention, lubrication, or enhanced wear resistance. Traditional oil immersion equipment typically employs a simple soaking method, which suffers from uneven oil immersion, low processing efficiency, and significant oil waste. Although existing technologies have incorporated ultrasonic technology to improve the oil immersion effect, such as enhancing oil penetration through ultrasonic cavitation, most equipment has a simple structure, unreasonable ultrasonic generator arrangement, and a single direction of sound wave emission, resulting in limited processing effectiveness.

[0003] Therefore, there is a need for a novel, efficient, and adaptable through-type ultrasonic oil immersion line. Utility Model Content

[0004] The purpose of this invention is to provide a through-type ultrasonic oil impregnation line device. Through optimized structural design, multiple ultrasonic transducers arranged at multiple angles and in different areas form an interwoven ultrasonic field, avoiding energy dead zones and performing continuous all-round ultrasonic oil impregnation treatment on metal workpieces. This greatly improves the rust prevention, lubrication or penetration effect and solves the problems of uneven oil impregnation and low efficiency in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] Please refer to Figures 1-4This embodiment provides a through-type ultrasonic oil immersion line device, including a stainless steel frame 1. The frame 1 is equipped with an oil immersion tank 2, a control device 3, and a conveyor belt device 4 for driving workpieces 9 through the oil in the oil immersion tank 2. The oil immersion tank 2 is equipped with an ultrasonic device 5, which includes an ultrasonic generator 51, multiple first ultrasonic transducers 52, multiple second ultrasonic transducers 53, and multiple third ultrasonic transducers 54. Each of the first ultrasonic transducers 52, second ultrasonic transducers 53, and third ultrasonic transducers 54 is connected to the ultrasonic generator 51, and the ultrasonic generator 51 is connected to the control device 3. Specifically, the first ultrasonic transducers 52 are symmetrically and sealed to the upper part of the two long side walls of the oil immersion tank 2 via waterproof flanges, and their sound wave emission direction is downward. The second ultrasonic transducers 53 are symmetrically and sealed to the lower part of the two long side walls of the oil immersion tank 2 via waterproof flanges, and their sound wave emission direction is upward. The third ultrasonic transducers 54 are sealed to the bottom wall of the oil immersion tank 2 via waterproof flanges, and their sound wave emission direction is vertically upward.

[0026] Through the above structural design, multiple ultrasonic transducers arranged at multiple angles and in different areas form a three-dimensional, interwoven ultrasonic energy field within the oil immersion tank 2. This achieves a more uniform ultrasonic energy distribution, avoids energy dead zones, and ensures that the workpiece 9 receives uniform ultrasonic action regardless of its position within the oil immersion tank 2. This enables continuous, all-around ultrasonic oil immersion treatment of the workpiece 9, significantly improving oil penetration and processing efficiency (approximately 30% higher than conventional single-direction setups). Simultaneously, the overall structure is compact, suitable for continuous production lines, saving space and energy consumption.

[0027] In some preferred embodiments, such as Figure 1 As shown, the first ultrasonic transducer 52, the second ultrasonic transducer 53, and the third ultrasonic transducer 54 are all evenly spaced along the length of the oil immersion tank 2. Specifically, the spacing is 10cm to 50cm. As an example, the spacing can be designed to be 30cm.

[0028] In some preferred embodiments, such as Figure 2 As shown, the sound wave emission direction of the first ultrasonic transducer 52 is distributed downward at an angle of 20° to 45°, and the sound wave emission direction of the second ultrasonic transducer 53 is distributed upward at an angle of 10° to 30°. This allows for a better ultrasonic oil impregnation treatment effect.

[0029] Specifically, as an example, the upper portions of the two long sidewalls of the oil immersion tank 2 are each equipped with three first ultrasonic transducers 52. The sound waves emitted by the first ultrasonic transducers 52 are distributed downward at a 30° angle, pointing towards the lower part of the tank. The lower portions of the two long sidewalls of the oil immersion tank 2 are each equipped with three second ultrasonic transducers 53. The sound waves emitted by the second ultrasonic transducers 53 are distributed upward at a 15° angle, pointing towards the upper middle part of the tank. The bottom wall of the oil immersion tank 2 is equipped with three third ultrasonic transducers 54. The sound waves emitted by the third ultrasonic transducers 54 are vertically upward. The power of the first ultrasonic transducers 52, the second ultrasonic transducers 53, and the third ultrasonic transducers 54 is 500W, and the frequency is 28kHz.

[0030] As an improved implementation method, refer to Figure 1 and Figure 4 The oil immersion tank 2 is equipped with an oil circulation device 6 for filtering impurities. The oil circulation device 6 includes a circulation pump 62 and a filter 63 installed on a circulation pipe 61. The circulation pump 62 is electrically connected to a control device 3. An oil outlet 21 is located at the bottom of the oil immersion tank 2, and an oil return port 22 is located at the top of the tank. The oil outlet 21 and the oil return port 22 are connected to both ends of the circulation pipe 61, respectively. The circulation pump 62 pumps the oil out of the oil immersion tank 2, filters it through the filter 63 to remove impurities, and then returns it to the oil immersion tank 2, effectively maintaining the cleanliness of the oil and extending the service life of both the oil and the equipment.

[0031] In some specific embodiments, filter 63 is a cartridge filter 63. As an example, filter 63 adopts a high-flow cartridge filter 63 from Qingdao Kerui Filter Co., Ltd., with a filtration accuracy of 5μm, which can effectively remove impurities such as particulate matter and metal shavings from the oil.

[0032] In some implementations, reference Figure 1 , Figure 3 and Figure 4 The circulation pipe 61 is further connected to a heating device 7 for heating the oil. Specifically, the heating device 7 includes a plate 71 with heating channels 711 and electric heating wires 72 located inside the plate 71 and wound around the heating channels 711. The plate 71 has interfaces that are respectively connected to both ends of the heating channels 711. The oil immersion tank 2 is equipped with a temperature sensor 35 for detecting the oil temperature. The electric heating wires 72 and the temperature sensor 35 are electrically connected to the control device 3. When the oil flows through the heating channels 711, it can be heated to a suitable optimal operating temperature (such as 50℃~60℃), extending the service life of the oil and equipment.

[0033] refer to Figure 1 and Figure 4As a further improved implementation, the frame 1 is equipped with a preheating device 8 near the input end of the workpiece 9 to raise the surface temperature of the workpiece 9. Specifically, the preheating device 8 includes a housing 81 covering the conveyor belt device 4 with its opening facing downwards, and a plurality of parallel infrared heating tubes 82 arranged in the housing 81. The infrared heating tubes 82 are electrically connected to the control device 3. An air distribution plate 83 is provided at the opening of the housing 81, and a blower 84 blowing downwards is provided at the top of the housing 81. The blower 84 is electrically connected to the control device 3, and the air distribution plate 83 has evenly distributed ventilation holes. By rapidly raising the surface temperature of the workpiece 9 through infrared radiation, and then evenly blowing hot air onto the workpiece 9 through the blower 84 and the air distribution plate 83, the problem of local overheating or uneven preheating is effectively avoided, so that the workpiece 9 reaches a uniform preheating temperature (e.g., set to 40℃~50℃). This preheating process reduces the viscosity of the oil, significantly enhancing the penetration speed and uniformity of subsequent ultrasonic impregnation. The uniformity of the treatment can be further improved by 20%, making it particularly suitable for precision parts with complex structures or sensitive to thermal stress.

[0034] In some specific implementations, such as Figure 1 As shown, the transmission belt device is composed of multiple segments, each segment including a motor-driven roller and an oil-resistant conveyor belt driven by the roller. The conveyor belt speed is infinitely adjustable within the range of 0.1~1m / s by controlling the motor speed via a frequency converter. This adjustable speed transmission system adapts to the processing cycle of different workpieces 9.

[0035] In some specific implementations, refer to Figure 1 and Figure 4 The control device 3 includes a waterproof electrical control box 31 installed on the side of the frame 1 and a PLC controller 32 located inside the waterproof electrical control box 31. The PLC controller 32 is connected to several operating switches 33 and is connected to a power supply 34. The operating switches 33 can be used to flexibly adjust and set operating parameters such as power, temperature, and time, so that the PLC controller 32 can centrally adjust and control the ultrasonic power, transmission speed, oil temperature, and cycle start and stop.

[0036] It should be noted that the ultrasonic transducer, PLC controller 32, temperature sensor 35, circulating pump 62, infrared heating tube 82, and blower 84 used in this application are all conventional electrical components, and appropriate products of suitable specifications can be selected according to actual usage requirements.

[0037] refer to Figures 1-4The working process is described as follows: The circulating pump 62 and heating device 7 are turned on to start oil circulation, maintaining the oil temperature at 55°C and continuously filtering. Before entering the immersion tank 2, the workpiece 9 passes through the preheating device 8, where it is rapidly and uniformly heated to a preset temperature (e.g., 45°C) under the combined action of infrared heating and uniform hot air. Subsequently, the preheated workpiece 9 immediately enters the immersion tank 2 via a conveyor belt at a set speed (e.g., 0.5 m / s) for ultrasonic immersion treatment. All ultrasonic transducers work together to generate a cavitation effect in the oil, while the workpiece 9's surface and internal pores are fully penetrated by the oil as it passes through the immersion tank 2. After treatment, the workpiece 9 is removed from the equipment for subsequent draining or cleaning processes. The entire process is continuously automated.

Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
