Description

Technical Field

[0001] This utility model belongs to the field of vibration reduction technology, specifically relating to a vibration reduction device for the base of a vacuum vibratory press. Background Technology

[0002] As a high-precision processing equipment, the vibration generated during the operation of a vacuum vibratory press, especially high-frequency impact and low-frequency resonance, can easily lead to a decrease in equipment stability, deviation in processing accuracy, and even accelerated wear of key components.

[0003] To suppress vibration transmission, the following vibration reduction schemes are commonly used in existing technologies, but they still have significant drawbacks. Single vibration reduction structures lack adaptability. Traditional vibration reduction devices often rely on single buffer elements (such as springs or rubber pads), which can only suppress vibrations in specific frequency bands. Spring dampers, while effectively absorbing low-frequency vibrations, have weak dissipation capacity for high-frequency impacts and are prone to plastic deformation due to instantaneous overload. Rubber pads / dampers, while quickly attenuating high-frequency vibrations, are prone to aging and cracking under long-term low-frequency alternating loads, resulting in significant degradation of vibration reduction performance. They also have poor adaptability to vibration direction. Most vibration reduction devices use rigid fixed structures, providing buffering only in a single direction (such as the vertical direction). However, vacuum vibratory presses often experience multi-directional vibrations (such as tilting, rotation, or lateral impacts) during actual operation. Fixed limit brackets cannot adapt to changes in vibration direction, causing non-axial impacts to be directly transmitted to the equipment base, exacerbating structural fatigue. Sliding friction pairs, in some designs, use sliding blocks to disperse lateral forces, but sliding friction easily generates wear debris, polluting the equipment environment, and the frictional resistance is unstable.

[0024] A vibration damping device for the base of a vacuum vibratory press includes,

[0025] Mobile station 1;

[0031] In a specific embodiment of this utility model, the mounting hole 202 facilitates the stable fixing of the bolt.

[0032] Specifically, the top of the outer wall of the shock absorber 2 is coated with a rubber layer.

[0033] In a specific embodiment of this utility model, a rubber layer is sprayed on the top of the outer wall of the shock absorber 2, which can improve the friction.

[0034] Specifically, the two ends of the positioning groove 201 extend outwards.

[0035] In a specific embodiment of this utility model, the two ends of the positioning groove 201 extend outward, which can improve positioning efficiency.

[0036] Specifically, a buffer layer is bonded to the bottom of the outer wall of the mobile station 1.

[0037] In a specific embodiment of this utility model, a buffer layer is bonded to the bottom of the outer wall of the mobile platform 1 to ensure stable placement.

[0038] Working principle:

[0039] The vibration source triggers the high-frequency impact or low-frequency vibration generated during the operation of the vacuum vibratory press, which is transmitted to the moving platform 1 through the equipment base. The vibration first acts on the bottom of the moving platform 1, where the buffer layer on its outer wall, such as rubber or elastic material, initially absorbs some of the high-frequency vibration energy, reducing the impact intensity directly transmitted to the damping components. The damper 4 responds quickly to the high-frequency vibration, which is transmitted to the damper 4 through the mounting bracket 3. The damper 4 rapidly consumes the vibration energy through its internal viscous fluid or friction plates, suppressing the transmission of high-frequency impact. One end of the damper 4 is fixed to the mounting bracket 3 of the moving platform 1, and the other end is connected to the angle bracket 5, forming a rigid connection channel to ensure that the high-frequency energy is preferentially dissipated and buffered. Spring 9 elastically buffers low-frequency vibrations. These vibrations are transmitted to the support base 8 via the limiting frame 6, compressing the underlying buffer spring 9. The spring absorbs and releases low-frequency energy through a compression-rebound cycle, extending the vibration decay time. The spring's pre-compression design allows it to maintain elastic deformation even under instantaneous large loads, preventing plastic damage. Dynamic adjustment and energy conversion are achieved through the rolling guide wheel 7. Vibration energy drives the drag-reducing wheel 7 at the end of the limiting frame 6 to roll within the slot of the limiting frame 10, converting linear vibration into rotational kinetic energy and reducing direct damage to the structure from lateral impacts. The support base 8 moves synchronously with the drag-reducing wheel 7, dynamically dispersing the impact force to a larger contact surface of the limiting frame 10. To avoid stress concentration, the angle bracket 5 and the limiting bracket 6 are linked and adaptable. The angle bracket 5 can rotate around the opening of the limiting bracket 6, allowing the damping component to finely adjust its angle in three-dimensional space and automatically adapt to vibration transmission paths in different directions, such as tilting or rotational vibration. The positioning groove 201 and the mounting hole 202 are rigidly fixed. The positioning groove 201 on the top of the damping seat 2 fits into the protruding structure of the vacuum vibratory press base. The contact area is expanded by the extension design at both ends to achieve fast and accurate positioning. The mounting hole 202, together with bolts, rigidly connects the damping seat 2 to the equipment base to prevent displacement caused by long-term vibration. The rubber layer and the buffer layer provide synergistic protection. The sprayed rubber layer on the top of the damping seat 2 increases the contact with the equipment base. The static friction of the base prevents slippage; at the same time, it acts as a soft isolation layer to further weaken the transmission of high-frequency vibrations. The buffer layer at the bottom of the moving platform 1, such as polyurethane, absorbs minor ground vibrations when the equipment is placed, forming a double protection system. The energy is eventually dissipated and the system is reset. The vibration energy is dissipated in stages. The remaining vibration energy is dissipated through multiple stages such as damping 4, spring, and drag-reducing wheel 7, and is finally transmitted to the ground through the shock-absorbing seat 2 to avoid damage to the precision components inside the equipment. After the components are reset and the vibration stops, the buffer spring 9 pushes the support seat 8 to reset, and the drag-reducing wheel 7 rolls back to the initial position within the limit frame 10. The angle frame 5 and the limit frame 6 return to the neutral angle to prepare for the next vibration response.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
