Description

Technical Field

[0001] This utility model relates to the field of vibration damping structure technology, and more specifically, to a metal PU vibration damper. Background Technology

[0002] In today's various industrial production processes, the material feeding process is a key starting step to ensure the continuous operation of the production line. During the feeding process, the material is guided by the guide plate. However, the material will frequently collide with the guide plate during the guiding and conveying process. In order to avoid damage to the guide plate, a shock absorption mechanism is often set up.

[0003] Existing shock absorption methods often use conventional rubber buffer pads for cushioning. However, when faced with high-intensity and frequent material collisions, rubber buffer pads are prone to fatigue and aging, and their shock absorption effect rapidly diminishes, failing to effectively absorb impact energy. Therefore, a metal PU shock absorber is proposed. Utility Model Content

The bottom of the support plate is fixedly connected to a reinforcing rib, which improves the support strength of the support plate and prevents deformation of the support plate, thus affecting the performance of the PU panel. The bottom of the support plate is fixedly connected to a first fixing plate and a second fixing plate, and the bottom of both the first and second fixing plates is fixedly connected to a spring. The bottom of the spring is connected to a third fixing plate. Through the compression of the spring by the first and third fixing plates, the reverse thrust of the spring can achieve the function of buffering and shock absorption.

[0006] The bottom of the third fixed plate is fixedly connected to a shock-absorbing pad, and a connecting plate is fixedly connected between multiple third fixed plates. The bottom of the first fixed plate is fixedly connected to an arc-shaped plate, and the top two ends of the arc-shaped plate are symmetrically fixedly connected to first rubber rods. The bottom middle of the arc-shaped plate is fixedly connected to a second rubber rod. The shock-absorbing pad provides secondary buffering for the third fixed plate, the connecting plate improves the stability between multiple third fixed plates, the deformation of the arc-shaped plate further plays a role in buffering and shock absorption, and the compression of the second and first rubber rods generates deformation, which plays a role in damping and buffering, thereby achieving the role of buffering and shock absorption.

[0007] The two ends of the arc-shaped plate are symmetrically fixedly connected to limiting slide plates. A first sliding groove is provided in the middle of the limiting slide plate. A second sliding groove is provided on the top of the third fixed plate corresponding to the limiting slide plate. A limiting strip is fixedly connected in the middle of the second sliding groove. Through the cooperation of the limiting slide plate, the first sliding groove, the second sliding groove, and the limiting strip, the two ends of the arc-shaped plate can be limited and connected to the third fixed plate without affecting the sliding of the limiting slide plate caused by the deformation of the arc-shaped plate, thus improving the use effect.

[0008] Preferably, the reinforcing ribs are configured as a mesh structure and fixed to the bottom of the support plate. The first fixing plate and the second fixing plate are offset from the reinforcing ribs. The second fixing plate is disposed on both sides of the first fixing plate. The reinforcing ribs improve the support strength of the support plate.

[0009] Preferably, the top end of the first rubber rod is fixedly connected to the bottom wall of the support plate, and the bottom end of the second rubber rod is fixedly connected to the top wall of the third fixed plate. By pushing the first fixed plate and the arc plate with the first rubber rod and the second rubber rod, the first rubber rod and the second rubber rod can be squeezed when the arc plate deforms, thereby achieving the function of buffering and damping.

[0010] Preferably, the arc-shaped plate is disposed between multiple springs, and the arc-shaped plate is parallel to the connecting plate so as not to affect the deformation buffer of the springs.

[0011] Preferably, the limiting slide plate is adapted to the second slide groove, and the limiting plate is disposed in the middle of the second slide groove.

[0012] Preferably, the cross-sectional shape of the limiting strip is set to "T" shape, the first slide groove is adapted to the limiting strip, the limiting strip passes through the middle of the first slide groove, the limiting slide plate can not affect the deformation buffer of the arc plate, and the stability of the limiting slide plate is improved and the use effect is improved by the cooperation of the first slide groove and the limiting strip.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model first uses the support plate and the third fixing plate to compress the spring, and the deformation of the spring achieves the function of buffering and shock absorption. By compressing the arc plate, the deformation of the arc plate compresses the first rubber rod and the second rubber rod, which can further play the role of buffering and shock absorption. The first rubber rod and the second rubber rod can also play a damping role, reducing the vibration amplitude, improving the buffering and shock absorption effect, thereby increasing the service life of the first rubber rod and the second rubber rod, reducing the fatigue aging rate, and improving the use effect.

[0015] 2. This utility model can also improve the stability of multiple third fixed plates by setting a connecting plate, and improve the stability of arc plate deformation by setting a limiting slide plate to slide inside the second slide groove. The stability of the limiting slide plate is improved by the cooperation of the first slide groove and the limiting strip. The supporting strength and hardness of the support plate are improved by setting a reinforcing rib, so as to avoid deformation and damage to the support plate and improve the use effect.

[0016] In summary, through the interaction of the above-mentioned multiple effects, the deformation of the spring and the arc plate, along with the damping effect of the first and second rubber rods, can achieve the function of buffering and shock absorption, while also reducing vibration and the fatigue aging rate of the rubber material.

The bottom of the support plate 2 is fixedly connected with a reinforcing rib 4, which improves the support strength of the support plate 2 and prevents the support plate 2 from deforming, thus affecting the performance of the PU panel 3. The bottom of the support plate 2 is fixedly connected with a first fixing plate 5 and a second fixing plate 6. The bottom of both the first fixing plate 5 and the second fixing plate 6 is fixedly connected with a spring 7. The bottom of the spring 7 is connected with a third fixing plate 8. By compressing the spring 7 with the first fixing plate 5 and the third fixing plate 8, the reverse thrust of the spring 7 can achieve the function of buffering and shock absorption.

[0025] A shock-absorbing pad 10 is fixedly connected to the bottom of the third fixing plate 8. A connecting plate 9 is fixedly connected between multiple third fixing plates 8. An arc-shaped plate 11 is fixedly connected to the bottom of the first fixing plate 5. First rubber rods 12 are symmetrically fixedly connected to both ends of the top of the arc-shaped plate 11. A second rubber rod 13 is fixedly connected to the middle of the bottom of the arc-shaped plate 11. Limiting slide plates 14 are symmetrically fixedly connected to both ends of the arc-shaped plate 11. A first sliding groove 15 is provided in the middle of the limiting slide plate 14. A second sliding groove 16 is provided on the top of the third fixing plate 8 corresponding to the limiting slide plate 14. A limiting strip 17 is fixedly connected to the middle of the second sliding groove 16. The shock-absorbing pad 10 provides secondary buffering for the third fixed plate 8, the connecting plate 9 improves the stability between multiple third fixed plates 8, and the deformation of the arc plate 11 further buffers and reduces shock. The compression of the second rubber rod 13 and the first rubber rod 12 causes deformation, which acts as a damping buffer, thereby achieving the function of buffering and reducing shock. Through the cooperation of the limiting slide plate 14 and the first slide groove 15 with the second slide groove 16 and the limiting strip 17, the two ends of the arc plate 11 can be limited and connected to the third fixed plate 8 without affecting the sliding of the limiting slide plate 14 caused by the deformation of the arc plate 11, thus improving the performance.

[0026] As attached Figure 1-5As shown, the reinforcing rib 4 is configured as a mesh structure and fixed to the bottom of the support plate 2. The first fixing plate 5 and the second fixing plate 6 are offset from the reinforcing rib 4. The second fixing plate 6 is located on both sides of the first fixing plate 5. The top end of the first rubber rod 12 is fixedly connected to the bottom wall of the support plate 2, and the bottom end of the second rubber rod 13 is fixedly connected to the top wall of the third fixing plate 8. The arc-shaped plate 11 is located between multiple springs 7 and is parallel to the connecting plate 9. The limiting slide plate 14 is adapted to the second slide groove 16 and is located in the middle of the second slide groove 16. The cross-sectional shape of the limiting strip 17 is set as "T". The first slide groove 15 is adapted to the limiting strip 17, which passes through the middle of the first slide groove 15. The supporting strength of the support plate 2 is improved by the reinforcing rib 4. The first fixed plate 5 and the arc plate 11 are pushed by the first rubber rod 12 and the second rubber rod 13. When the arc plate 11 deforms, the first rubber rod 12 and the second rubber rod 13 are squeezed, thereby achieving the function of buffering and damping. The limiting slide plate 14 does not affect the deformation buffering of the arc plate 11. The stability of the limiting slide plate 14 is improved by the cooperation of the first slide groove 15 and the limiting strip 17, which improves the use effect and does not affect the deformation buffering of the spring 7.

[0027] The working principle of this utility model is as follows: When in use, the shock absorber is installed in a preset position. When the PU panel 3 is impacted, the spring 7 is compressed by the support plate 2, and the arc plate 11 is also compressed. The deformation of the spring 7 and the arc plate 11 can play a buffering role. At the same time, the deformation of the arc plate 11 will compress the first rubber rod 12 and the second rubber rod 13. The first rubber rod 12 and the second rubber rod 13 play a damping role, thereby achieving the buffering and shock absorption effect and improving the shock absorption effect.
