Description

Technical fields:

[0001] This utility model relates to the technical field of pipe pile production equipment, specifically to a vibration reduction and noise reduction device for a pipe mold centrifugal equipment. Background technology:

[0002] The existing support wheel structure of the tube mold centrifuge equipment uses symmetrically arranged support wheels to limit and support the tube mold, achieving stable centrifugal rotation. However, this structure has significant shortcomings: First, the support wheels are made of pure steel in a single piece, forming rigid contact with the inner wall of the tube mold during operation. Vibration is directly transmitted to the centrifuge frame, resulting in large overall vibration amplitude of the equipment. Long-term use can easily lead to problems such as loosening of centrifuge frame connectors and accelerated bearing wear. Second, the noise generated by rigid friction is high, which does not meet the environmental noise limits for workshops, and long-term exposure can damage the hearing health of operators. Third, there is a lack of targeted shock absorption and buffering structures, making it impossible to adapt to changes in the centrifugal rotation speed of the tube mold (such as low-speed forming and high-speed compaction stages) to meet vibration absorption requirements, which can easily lead to fluctuations in the forming accuracy of the inner wall of the tube mold. Therefore, this utility model proposes a vibration reduction and noise reduction device for tube mold centrifuge equipment to solve the shortcomings and defects of the existing technology. Utility Model Content:

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a vibration reduction and noise reduction device for tube mold centrifuge equipment.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A vibration damping and noise reduction device for a tube mold centrifuge includes a centrifuge frame and a centrifuge wheel mounted on the centrifuge frame. The centrifuge wheel includes two limiting wheels and a vibration damping and noise reduction wheel. The two limiting wheels are coaxially mounted on both sides of the vibration damping and noise reduction wheel by fixing bolts. A positioning block is fixedly provided on the inner axis of the centrifuge wheel, and a square hole is provided on the axis of the vibration damping and noise reduction wheel for the positioning block to be inserted.

[0006] Preferably, the shock-absorbing and noise-reducing wheel comprises a rigid wheel, rubber pillars, a protective layer, and a rubber wear-resistant layer. The edge of the rigid wheel is provided with multiple grooves, in which the rubber pillars are engaged. The rigid wheel is covered with a protective layer, and the protective layer is covered with a rubber wear-resistant layer. Elastic limiting filler is used to fill the space between the protective layer and the rubber pillars.

[0007] Preferably, the inner edge of the limiting wheel is provided with a graphite layer.

[0008] Preferably, the outer surface of the rubber wear-resistant layer is provided with anti-slip grooves.

[0009] According to the vibration damping and noise reduction device for the tube mold centrifuge according to the claim, the rubber wear-resistant layer is provided with a plurality of buffer through holes, preferably, and the rubber column shaft is provided with a second buffer through hole.

[0010] The beneficial effects of this utility model are as follows: This utility model achieves synergistic shock absorption and limiting functions through the split centrifugal wheel design. The rubber columns, buffer through holes, and elastic fillers of the shock-absorbing and noise-reducing wheel can absorb vibration in multiple layers, which can significantly reduce the vibration amplitude of the centrifugal frame. The rubber wear-resistant layer and graphite layer of this utility model reduce rigid friction, which can significantly reduce noise levels. The anti-slip groove and positioning block structure of this utility model ensure the stability of the tube mold operation and prevent slippage. The detachable limiting wheel facilitates component replacement and maintenance, and extends the service life of the equipment. Attached image description:

[0017] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0018] like Figure 1-6 As shown, a vibration damping and noise reduction device for a tube-mold centrifuge includes a centrifuge frame 001 and a centrifuge wheel 002 mounted on the centrifuge frame 001. The centrifuge wheel 002 includes two limiting wheels 210 and a vibration damping and noise reduction wheel 220. The two limiting wheels 210 are coaxially mounted on both sides of the vibration damping and noise reduction wheel 220 by fixing bolts. A positioning block 003 is fixedly provided on the inner axis of the centrifuge wheel 002. The axis of the vibration damping and noise reduction wheel 220 is provided with a square hole 004 for the positioning block 003 to be inserted. The positioning block 003 is fixed to the inner axis of the centrifuge wheel 002 by welding.

[0019] This solution is further optimized as follows: Figure 1-6 As shown, the shock-absorbing and noise-reducing wheel 220 consists of a rigid wheel 221, a rubber column 222, a protective layer 223, and a rubber wear-resistant layer 224. The edge of the rigid wheel 221 is provided with multiple grooves 2211, in which the rubber column 222 is engaged. The rigid wheel 221 is covered with a protective layer 223, and the protective layer 223 is covered with a rubber wear-resistant layer 224. The space between the protective layer 223 and the rubber column 222 is filled with an elastic limiting filler 225.

[0020] The protective layer 223 is made of polyurethane elastomer, the rubber wear-resistant layer 224 is made of neoprene rubber, and the elastic limiting filler 225 is a mixture of elastic rubber particles and epoxy resin with a filling density of over 90% to ensure filling density. The elastic limiting filler 225 fills the gap between the protective layer 223 and the rubber column 222 to prevent vibration from causing the component to shift.

[0021] This solution is further optimized as follows: Figure 1-6 As shown, the inner edge of the limiting wheel 210 is provided with a graphite layer 211. The graphite layer 211 is a coating made of high-purity graphite powder and resin to reduce the coefficient of friction with the end face of the tube mold.

[0022] This solution is further optimized as follows: Figure 1-6 As shown, the outer surface of the rubber wear-resistant layer 224 is provided with anti-slip grooves 2241. The anti-slip grooves 2241 on the outer surface of the rubber wear-resistant layer 224 are V-shaped grooves. The anti-slip grooves 2241 of the rubber wear-resistant layer 224 increase the friction with the inner wall of the tube mold and prevent slipping.

[0023] This solution is further optimized as follows: Figure 1-6 As shown, the rubber wear-resistant layer 224 is provided with multiple buffer through holes 2242, which initially absorb the vibration of the tube mold in contact with the wheel body.

[0024] This solution is further optimized as follows: Figure 1-6 As shown, the rubber column 222 has a buffer through hole 2221 on its shaft. The rubber column 222 is made of nitrile rubber and its diameter is adapted to the groove 2211. The diameter and length of the buffer through hole 2221 on the shaft are consistent with the rubber column. When the vibration amplitude of the tube mold increases, the rubber column 222 is squeezed and deformed, and the buffer through hole 2221 shrinks, further absorbing radial vibration.

[0025] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
