Description

Technical Field

[0001] This utility model relates to the field of hydraulic components, and more specifically, to a low-noise silencing cover for hydraulic components. Background Technology

[0002] Hydraulic components are the core functional elements of a hydraulic system, including hydraulic pumps, hydraulic valves, hydraulic cylinders, hydraulic motors, and hydraulic accessories (such as pipe fittings and seals). They realize the power control, motion adjustment, and load drive of mechanical equipment through the conversion and transmission of liquid pressure energy. They are characterized by high power density, fast response speed, excellent control precision, and strong overload protection. They are widely used in engineering machinery, industrial equipment, aerospace, agricultural machinery, and other fields. Their performance directly affects the efficiency, reliability, and service life of the system. In order to reduce the noise emitted by hydraulic components during operation, a hydraulic press noise reduction cover is required.

[0003] A search revealed that Chinese patent CN202251218U discloses a "dustproof and low-noise hydraulic cylinder." The protective cover consists of a fixed cover and a movable cover. The fixed cover is located outside the cylinder body, with one end connected to the cylinder body via fasteners and the other end connected to the cylinder bottom pin. A cavity is formed inside the fixed cover. The movable cover is located outside the piston rod, with one end connected to the cylinder front pin and the other end extending into the cavity of the fixed cover and connecting to it. A muffler is provided on the cylinder body. This invention has a simple structure, high stability, self-protection effect, low noise, and low failure rate. However, it still has the following drawbacks:

[0004] (1) Most of the low-noise silencers for hydraulic components on the market now require manual opening and closing of the hydraulic cover. They do not provide a fast and efficient automatic opening and closing effect, which increases the workload of the staff, increases the complexity of the work, and reduces the overall work efficiency.

[0005] (2) It does not provide the effect of conveniently adjusting the height and position of the overall structure, which reduces the overall adaptability of the structure to the environment, reduces the applicable scenarios of the structure, and is not conducive to the use of the structure in multiple environments. Therefore, a low-noise silencing cover for hydraulic components is proposed. Utility Model Content

[0006] The purpose of this invention is to address the current problem of the lack of fast and efficient automatic opening and closing mechanisms.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a low-noise silencing cover for hydraulic components, comprising a worktable, a lower mold fixedly connected to the top of the worktable, a support frame fixedly connected to the top of the worktable, a hydraulic power supply component fixedly connected to the top of the support frame, a hydraulic rod fixedly connected to the bottom of the hydraulic power supply component, an upper mold fixedly connected to the bottom end of the hydraulic rod, a rear frame fixedly connected to the top of the worktable, and an adjustment motor fixedly connected to the top of the rear frame.

A movable long plate is movably connected to the outer wall of the rotating threaded column. A polyester fiber cotton sound insulation frame is fixedly connected to one side of the movable long plate. A limit column is movably connected to the bottom of the movable long plate. This allows the low-noise silencing cover to be opened and closed automatically without manual operation, providing a fast and efficient opening and closing effect. This reduces the workload and complexity of the workers, and improves the overall work efficiency.

[0010] As a preferred technical solution of this utility model, the bottom of the workbench is fixedly connected with an electric push rod, and the number of electric push rods is four.

[0012] As a preferred technical solution of this utility model, the top of the mounting plate is movably connected with mounting bolts, and there are two mounting plates, with two mounting bolts on the top of each mounting plate.

[0013] As a preferred technical solution of this utility model, the bottom of the workbench is movably connected to a locking bolt, and the outer wall of the locking bolt is movably connected to a handling handle.

[0014] As a preferred technical solution of this utility model, the top of the workbench is fixedly connected to the bottom of the rear frame, and the height of the rear frame is greater than the height of the support frame.

[0018] 2. The electric push rod, mounting plate, mounting bolts, locking bolts, and handling handle facilitate the overall connection and handling of the structure, as well as the height adjustment of the structure.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] As shown in 1-5, this embodiment proposes a low-noise silencing cover for hydraulic components, including a workbench 1, a lower mold 2 fixedly connected to the top of the workbench 1, a support frame 3 fixedly connected to the top of the workbench 1, a hydraulic power supply component 4 fixedly connected to the top of the support frame 3, a hydraulic rod 5 fixedly connected to the bottom of the hydraulic power supply component 4, an upper mold 6 fixedly connected to the bottom end of the hydraulic rod 5, a rear frame 7 fixedly connected to the top of the workbench 1, and an adjustment motor 8 fixedly connected to the top of the rear frame 7.

[0030] The output shaft of the adjustment motor 8 is fixedly connected to a rotating threaded column 9 via a coupling. A movable long plate 10 is movably connected to the outer wall of the rotating threaded column 9. A polyester fiber cotton sound insulation frame 11 is fixedly connected to one side of the movable long plate 10. A limit column 12 is movably connected to the bottom of the movable long plate 10. The low noise silencing cover can be opened and closed without manual operation, providing a fast and efficient automatic opening and closing effect. This reduces the workload of the staff, lowers the complexity of their work, and improves the overall work efficiency.

[0031] As shown in 1-5, in a preferred embodiment, based on the above method, the bottom of the workbench 1 is fixedly connected with an electric push rod 13, and there are four electric push rods 13, which can adjust the overall working height of the structure. The bottom end of the electric push rod 13 is fixedly connected with a mounting plate 14, and the length of the mounting plate 14 is greater than the length of the workbench 1, which improves the stability of the structure during operation. The top of the mounting plate 14 is movably connected with a mounting bolt 15, and there are two mounting plates 14, with two mounting bolts 15 on the top of each mounting plate 14, which facilitates fixing the working position of the structure. The bottom of the workbench 1 is movably connected with a locking bolt 16, and the outer wall of the locking bolt 16 is movably connected with a handling handle 17, which facilitates the overall handling of the device.

[0032] The top of the workbench 1 is fixedly connected to the bottom of the rear frame 7, and the height of the rear frame 7 is greater than the height of the support frame 3, which provides support for the connection structure. The bottom of the movable long plate 10 is movably connected to the outer wall of the limiting long column 12, and the length of the limiting long column 12 is equal to the length of the rotating threaded column 9, which allows the movable long plate 10 to move in a stable linear motion.

[0033] Specifically, when using this hydraulic low-noise silencing cover: first, move the entire structure to the working position using the handling handle 17, then fix the mounting plate 14 to the working position by rotating the mounting bolts 15. The electric push rod 13 rises so that the worktable 1 reaches the appropriate working height. At this time, place the part to be processed on the top of the lower mold 2. The adjustment motor 8 works, and the output shaft of the adjustment motor 8 rotates to make the rotating threaded column 9 rotate. The rotation of the rotating threaded column 9 makes the movable long plate 10 drive the polyester fiber cotton sound insulation frame 11 to move downward, so that the polyester fiber cotton sound insulation frame 11 can fit with the worktable 1. At this time, the hydraulic power supply component 4 works, so that the hydraulic rod 5 creates a sound field, completing the hydraulic pressure of the upper mold 6 on the parts on the lower mold 2. At the same time, the polyester fiber cotton sound insulation frame 11 can reduce the noise generated during the operation.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
