Description

Technical Field

[0001] This utility model relates to the field of hydraulic pump technology, and in particular to a low-noise hydraulic pump assembly installation device for a servo hydraulic press. Background Technology

[0002] A hydraulic pump is a power component in a hydraulic system. Driven by an engine or electric motor, it draws hydraulic fluid from a tank, pressurizes it, and delivers it to the actuators. Hydraulic pumps are classified by structure into gear pumps, piston pumps, vane pumps, and screw pumps.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: existing hydraulic pumps generate a lot of noise during installation and use. Long-term exposure of operators to this noise environment can lead to irreversible hearing loss or even occupational deafness. Moreover, high noise can mask abnormal noises of equipment malfunctions (such as friction sounds before bearing failure or impact sounds of loose parts) or warning shouts from colleagues, increasing the risk of safety accidents. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the installation and use of hydraulic pumps will generate a lot of noise, which has a significant impact on personnel health, equipment safety and production costs. To this end, we propose a low-noise hydraulic pump group installation device for servo hydraulic presses.

[0005] To achieve the above objectives, this application adopts the following technical solution: a low-noise hydraulic pump assembly installation device for a servo hydraulic press, comprising a housing, a mounting base fixed at the bottom of the housing, a connecting plate at the top of the mounting base, a hydraulic pump body fixed at the top of the connecting plate, first threaded holes at each of the four corners of the connecting plate, and second threaded holes at each of the four corners of the top of the mounting base. The connecting plate is fixed to the mounting base with bolts through the first and second threaded holes. A sealing cover is rotatably connected to the top of the housing via a hinge. A pipe hole for cooperating with the hydraulic pump body is opened at the front end of the housing. A first sound insulation pad is installed inside the housing, and a second sound insulation pad is installed at the bottom of the housing.

[0006] Preferably, a third sound-insulating pad is installed on one side of the sealing cover.

[0007] Preferably, heat dissipation holes are provided on both sides of the housing.

[0008] Preferably, grooves are formed on the outer surfaces of both sides of the housing, and cooling fans are installed inside the grooves.

[0009] Preferably, a shock-absorbing pad is installed on the top of the mounting base, the connecting plate is located on top of the shock-absorbing pad, and through holes are provided at the four corners of the shock-absorbing pad to cooperate with the first threaded hole and the second threaded hole.

[0010] Preferably, a sealing strip is installed on the top of the housing, and a sealing groove is provided on one side of the sealing cover to cooperate with the sealing strip.

[0011] Preferably, one end of the sealing cover is rotatably connected to a rotating block via a rotating shaft, a limiting block is provided on the side of the rotating block away from the sealing cover, one side of the limiting block is fixed to the rotating shaft, a slot is provided on the side of the rotating block away from the rotating shaft, and a limiting rod that cooperates with the slot is fixed on one side of the housing.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, by isolating vibration and absorbing and isolating noise, the noise emitted by the hydraulic pump body during operation can be greatly reduced, avoiding long-term exposure of operators to such a noisy environment. At the same time, it avoids the abnormal noise of equipment failure or warning shouts from colleagues due to high noise, thus reducing the risk of safety accidents.

[0013] In this invention, after the sealing cover and the housing are closed, the rotating block is rotated to engage the slot with the limiting rod, thereby fixing the position of the sealing cover and preventing it from moving due to lack of a limiting position, which would affect the overall sealing effect.

[0016] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0017] Reference Figures 1-4 As shown, this utility model provides a technical solution: a low-noise hydraulic pump assembly installation device for a servo hydraulic press, including a housing 1, a mounting base 2 fixed at the bottom inside the housing 1, a connecting plate 3 provided at the top of the mounting base 2, a shock-absorbing pad 15 installed at the top of the mounting base 2, the connecting plate 3 located at the top of the shock-absorbing pad 15, and through holes 16 for use with first threaded holes 5 and second threaded holes 6 at the four corners of the shock-absorbing pad 15, a hydraulic pump body 4 fixed at the top of the connecting plate 3, a first threaded hole 5 at the four corners of the connecting plate 3, and a second threaded hole 6 at the four corners of the top of the mounting base 2, the connecting plate 3 being fixed to the mounting base 2 with bolts through the first threaded holes 5 and the second threaded holes 6, a sealing cover 7 being rotatably connected to the top of the housing 1 via a hinge, a pipe hole 8 for use with the hydraulic pump body 4 being opened at the front end of the housing 1, a first sound insulation pad 9 installed inside the housing 1, a second sound insulation pad 10 installed at the bottom inside the housing 1, and a third sound insulation pad 11 installed on one side of the sealing cover 7; Specifically: The connecting plate 3 is installed on the top of the mounting base 2. Before installation, the shock-absorbing pad 15 is placed between the connecting plate 3 and the mounting base 2. The connecting plate 3 and the mounting base 2 are connected by bolts. Then, the top of the housing 1 is closed by the sealing cover 7. The housing 1 and the sealing cover 7 form a cavity to physically isolate the noise generated by the hydraulic pump body 4 during operation. The first sound insulation pad 9 and the second sound insulation pad 10 inside the housing 1, as well as the third sound insulation pad 11 installed at the bottom of the sealing cover 7, absorb the noise generated by the hydraulic pump body 4 during operation. The shock-absorbing pad 15 can effectively isolate high-frequency vibration. Through the isolation of vibration and the absorption and isolation of noise, the noise transmitted by the hydraulic pump body 4 during operation can be greatly reduced, avoiding long-term exposure of operators to such a noisy environment. At the same time, it avoids the high noise masking of abnormal noises of equipment failure or warning shouts from colleagues, reducing the risk of safety accidents.

[0018] Reference Figure 3 As shown, in this embodiment: heat dissipation holes 12 are provided on both sides of the housing 1, and grooves 13 are provided on the outer surfaces of both sides of the housing 1, with a cooling fan 14 installed inside the groove 13; Specifically: the heat dissipation holes 12 allow for ventilation and heat dissipation inside the housing 1, preventing the internal temperature of the housing 1 from becoming too high; the cooling fan 14 enables active heat dissipation, improving the overall heat dissipation effect.

[0019] Reference Figure 4 As shown, in this embodiment: a sealing strip 17 is installed on the top of the housing 1, and a sealing groove 18 that cooperates with the sealing strip 17 is opened on one side of the sealing cover 7; Specifically: By using the sealing strip 17 in conjunction with the sealing groove 18, when the sealing cover 7 is closed to the top of the housing 1, the gap between the closed parts is sealed, reducing noise leakage.

[0020] Reference Figure 3 As shown in this embodiment: one end of the sealing cover 7 is rotatably connected to a rotating block 19 via a rotating shaft. A limiting block 20 is provided on the side of the rotating block 19 away from the sealing cover 7. One side of the limiting block 20 is fixed to the rotating shaft. A slot 21 is provided on the side of the rotating block 19 away from the rotating shaft. A limiting rod 22 that cooperates with the slot 21 is fixed on one side of the housing 1. Specifically: After the sealing cover 7 and the housing 1 are closed, the rotating block 19 is rotated to make the slot 21 engage with the limiting rod 22, thereby fixing the position of the sealing cover 7 and preventing the sealing cover 7 from moving due to lack of limiting, which would affect the overall sealing effect.

[0021] Working principle: The connecting plate 3 is installed on top of the mounting base 2. Before installation, the shock-absorbing pad 15 is placed between the connecting plate 3 and the mounting base 2. The connecting plate 3 and the mounting base 2 are connected by bolts. Then, the top of the housing 1 is closed by the sealing cover 7. After the sealing cover 7 and the housing 1 are closed, the rotating block 19 is rotated to make the slot 21 engage with the limiting rod 22, thereby fixing the position of the sealing cover 7 and preventing the sealing cover 7 from moving due to lack of limiting, which would affect the overall sealing effect. Through the cooperation of the sealing strip 17 and the sealing groove 18, when the sealing cover 7 and the top of the housing 1 are closed, the gap of the closure is sealed, reducing noise leakage. The housing 1 is configured to form a cavity, which physically isolates the noise generated by the hydraulic pump body 4 during operation. The first sound insulation pad 9 and the second sound insulation pad 10 inside the housing 1, as well as the third sound insulation pad 11 installed at the bottom of the sealing cover 7, absorb the noise generated by the hydraulic pump body 4 during operation. The damping pad 15 can effectively isolate high-frequency vibration. Through the isolation of vibration and the absorption and isolation of noise, the noise transmitted by the hydraulic pump body 4 during operation can be greatly reduced. The heat dissipation hole 12 can ventilate and dissipate heat inside the housing 1, preventing the temperature inside the housing 1 from becoming too high. The cooling fan 14 can actively dissipate heat, improving the overall heat dissipation effect.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
