Abstract
Description
Technical Field
[0001] This application relates to the field of shell structure technology, and in particular to a built-in damping vibration reduction structure for a press frame. Background Technology
[0002] When a press is in operation, the internal moving parts will generate continuous vibration. The metal frame will not only transmit this vibration, but also amplify it. This will not only make the noise during operation very noticeable, but the continuous vibration will also accelerate the fatigue damage of the parts. Utility Model Content
[0003] The purpose of this application is to provide a built-in damping vibration reduction structure for a press frame that can prevent the transmission of vibration.
[0004] To achieve the above objectives, this application provides a built-in damping vibration reduction structure for a press frame: including a pair of parallel left and right side plates, a pair of parallel front and rear side plates fixedly connected between the two left and right side plates, a flow-blocking plate fixedly connected between the left and right side plates and located between the two front and rear side plates, a support frame provided between the flow-blocking plate and the two front and rear side plates, each support frame having upper and lower flow holes and left and right flow holes, the flow-blocking plate having front and rear flow holes penetrating the front and rear surfaces, upper and lower side plates fixedly connected to the upper and lower ends of the front and rear side plates, and the cavity formed by the front and rear side plates, left and right side plates and upper and lower side plates being suitable for injecting fluid, using the frictional resistance of fluid flow to consume vibration energy.
[0005] As a preferred embodiment, each of the support frames includes several transverse partitions and several longitudinal partitions, with all the transverse partitions fixedly connected to all the longitudinal partitions, and all the longitudinal partitions fixedly connected to all the transverse partitions, forming a continuous "well" structure.
[0006] As a preferred embodiment, all the transverse partitions of the same support frame are arranged in parallel and at equal intervals, and all the longitudinal partitions of the same support frame are arranged in parallel and at equal intervals, so as to uniformly provide support between the baffle plate and the front and rear side plates.
[0007] As a preferred embodiment, the upper and lower flow holes are formed on the transverse partitions and located between adjacent longitudinal partitions, and the left and right flow holes are formed on the longitudinal partitions and located between adjacent transverse partitions, so that the left and right flow holes in the same row are aligned and the upper and lower flow holes in the same column are aligned, which facilitates the drilling operation.
[0008] As a preferred embodiment, the front and rear flow holes are located between the adjacent transverse diaphragms and also between the adjacent longitudinal diaphragms, to prevent the front and rear flow holes from being blocked by the transverse or longitudinal diaphragms.
[0009] As a preferred embodiment, the baffle plate has a central through hole, and the front and rear side plates have end through holes. The two end through holes are coaxial and aligned with the central through hole. A bushing is fixedly connected to the central through hole and the two end through holes to constrain the rotating shaft structure of the press.
[0010] As a preferred embodiment, the bushing, front and rear side plates, left and right side plates, upper and lower side plates, support frame and baffle plate are all made of corrosion-resistant alloy material to ensure the strength and stability of the structure.
[0011] As a preferred option, each of the support frames is integrally injection molded from plastic, reducing weight and operating costs.
[0012] Compared with the prior art, the beneficial effects of this application are as follows:
[0013] (1) By designing the cavity structure and opening convection holes in the front-back, left-right, and up-down directions in the cavity, the fluid injected into the cavity can consume vibration energy through the frictional resistance during flow, thereby suppressing the transmission of vibration and reducing the generation of noise.
[0014] (2) This design can not only be set inside the frame to directly contact the frame to suppress vibration, but also directly serve as a frame or shell structure to constrain moving parts, thus having a good vibration reduction effect. Attached Figure Description

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0025] like Figure 1-5 The built-in damping vibration reduction structure of the press frame shown includes a pair of parallel left and right side plates 3, with the upper and lower ends of the two left and right side plates 3 aligned. A pair of parallel front and rear side plates 2 are fixedly connected between the two left and right side plates 3. The top edge of the two front and rear side plates 2 is flush with the upper end of the left and right side plates 3, and the bottom edge is flush with the lower end of the left and right side plates 3. A flow baffle 6 is also fixedly connected between the left and right side plates 3 and located between the two front and rear side plates 2. The flow baffle 6 is parallel to the two front and rear side plates 2 and is equidistant from the two front and rear side plates 2.
[0026] A support frame 5 is provided between the baffle plate 6 and the two front and rear side plates 2. Each support frame 5 is integrally injection molded from plastic, and each support frame 5 has upper and lower flow holes 503 and left and right flow holes 504. Specifically, each support frame 5 includes several transverse partitions 501 and several longitudinal partitions 502. It should be noted that all transverse partitions 501 are fixedly connected to all longitudinal partitions 502, and all longitudinal partitions 502 are fixedly connected to all transverse partitions 501 to form an integral structure. All transverse partitions 501 of the same support frame 5 are parallel and equidistantly arranged, and all longitudinal partitions 502 of the same support frame 5 are also parallel and equidistantly arranged. The upper and lower flow holes 503 are opened on the transverse partitions 501 and are located between adjacent longitudinal partitions 502. The upper and lower flow holes 503 allow liquid to flow in the vertical direction. The left and right flow holes 504 are opened on the longitudinal partitions 502 and are located between adjacent transverse partitions 501. The left and right flow holes 504 allow liquid to flow in the horizontal direction.
[0027] The baffle plate 6 has front and rear flow holes 602 that penetrate the front and rear surfaces. The front and rear flow holes 602 are located between adjacent transverse baffles 501 and between adjacent longitudinal baffles 502. The front and rear flow holes 602 allow liquid to flow in the front and rear direction.
[0028] The front and rear side plates 2 are fixedly connected to the upper and lower ends of the upper and lower side plates 4. The bushing 1, the front and rear side plates 2, the left and right side plates 3, the upper and lower side plates 4, the support frame 5 and the baffle plate 6 are all made of corrosion-resistant alloy materials to ensure structural strength. The cavity formed by the front and rear side plates 2, the left and right side plates 3 and the upper and lower side plates 4 is suitable for filling with fluid, usually hydraulic oil. On the one hand, hydraulic oil is not corrosive, and on the other hand, hydraulic oil can consume vibration energy when it flows, so as to achieve the effect of damping and vibration reduction.
[0029] The baffle plate 6 has a central through hole 601, and the front and rear side plates 2 have end through holes 201. The two end through holes 201 are coaxial and aligned with the central through hole 601. A bushing 1 is fixedly connected to the central through hole 601 and the two end through holes 201. The bushing 1 is used to install a bearing structure and to limit the rotating shaft structure of the press.
[0030] Working principle: The cavity formed by the front and rear side plates 2, left and right side plates 3, and upper and lower side plates 4 does not need to be filled with hydraulic oil. Generally, it is sufficient to fill it to 80% to 90% of the upper limit of capacity. When the press vibrates during operation, regardless of the direction of vibration, the hydraulic oil can flow back and forth through one or three of the upper and lower flow holes 503, left and right flow holes 504, and front and rear flow holes 602. During the process of hydraulic oil flowing through the fine holes, due to frictional resistance, the kinetic energy will be converted into heat energy, thereby consuming vibration energy. This structure can be set in the frame or used as a protective shell for the moving mechanism to achieve the function of damping and vibration reduction.
[0031] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
