Description

Technical Field

[0001] This application relates to the field of punch press auxiliary mechanism technology, and in particular to a vibration suppression structure for a heavy-duty punch press base. Background Technology

[0002] When a heavy-duty punch press is in operation, the large mass of its moving parts causes significant vibrations, and the base of the punch press exerts a strong reciprocating load on the ground, which can easily damage the floor where it is installed. Utility Model Content

[0003] The purpose of this application is to provide a vibration suppression structure that can reduce ground damage caused by heavy-duty punch presses.

[0004] To achieve the above objectives, this application provides a vibration suppression structure for a heavy-duty punch press base: comprising a hydraulic cylinder, a cover, and a piston body. The hydraulic cylinder includes a base plate, and a rectangular cylinder is fixedly connected to the upper surface of the base plate. The rectangular cylinder is suitable for injecting fluid. The cover is fixedly connected to the hydraulic cylinder by bolts, and the cover has a guide hole penetrating the upper and lower surfaces. The piston body includes a rectangular plug plate located inside the rectangular cylinder. The rectangular plug plate is suitable for cooperating with the rectangular cylinder to form a sliding pair. A convection hole penetrating the upper and lower surfaces is opened in the center of the rectangular plug plate. A guide post is fixedly connected to the upper surface of the rectangular plug plate, suitable for cooperating with the guide hole to form a sliding pair, further constraining the degree of freedom of movement of the piston body and improving the stability and reliability of the piston body's up-and-down movement.

[0005] As a preferred embodiment, a bottom rubber pad is provided at the bottom of the rectangular cylinder to prevent the piston body from making direct hard contact with the bottom wall of the cylinder.

[0006] As a preferred embodiment, the cover includes a pressing plate, the lower surface of which has an insert plate adapted to be embedded in the rectangular cylinder for installation and positioning.

[0007] As a preferred embodiment, a top rubber pad is fixedly connected to the lower surface of the insert plate. The top rubber pad has a clearance hole aligned with the guide hole to avoid motion interference with the guide post.

[0008] As a preferred embodiment, the pressing plate has a through hole on the portion outside the inner plate, and the top surface of the rectangular cylinder has an internal threaded hole aligned with the through hole. The bolt is adapted to pass through the through hole and engage with the internal threaded hole to achieve a tightened and fixed connection.

[0009] As a preferred embodiment, the upper end of the guide column is fixedly connected to a support plate, and the upper surface of the support plate is provided with a recessed hole; the bottom support plate is provided with a connection hole in the part outside the rectangular cylinder, so that the connecting parts can pass through and be fixedly connected to the ground.

[0010] As a preferred embodiment, the outer side of the rectangular plug plate is provided with a sealing ring groove, and a piston sealing ring is provided in the sealing ring groove of the rectangular plug plate. The cover is provided with a coaxial inner mounting groove on the inner wall of the guide hole, and a plug rod sealing ring is provided in the inner mounting groove to prevent hydraulic oil from overflowing through the gap between the guide post and the cover.

[0011] As a preferred embodiment, the outer side of the inner panel is provided with an outer configuration groove, and a rubber ring is provided in the outer configuration groove of the inner panel to prevent hydraulic oil from overflowing from the mating gap between the cover and the cylinder.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a reasonable piston body and oil cylinder to form a liquid damping structure, the vibration energy is converted into heat energy by the friction of liquid flow, thereby effectively suppressing the vibration transmission of heavy punch press to the bottom surface and reducing the damage to the ground when the heavy punch press is working.

[0014] (2) Since the piston body has a relatively small range of vertical movement, the height of the vibration suppression structure is relatively small and it occupies less space. The cylinder and piston body are designed as rectangles, which can be well adapted to the bottom shape of the press. Attached Figure Description

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] 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.

[0030] like Figure 1-10 The vibration suppression structure of the heavy-duty punch press base shown includes a hydraulic cylinder 1, a cover 2, and a piston body 5. The hydraulic cylinder 1 is fixedly connected to the ground, the cover 2 is fixedly connected to the hydraulic cylinder 1, and the piston body 5 is fixedly connected to the punch press base. The hydraulic cylinder 1 includes a base plate 101 that is in direct contact with the ground. A rectangular cylinder 102 is fixedly connected to the upper surface of the base plate 101. The cross-section of the base plate 101 is larger than that of the rectangular cylinder 102. The larger contact area with the ground is beneficial to reducing pressure. The part of the base plate 101 outside the rectangular cylinder 102 has a connecting hole 103 for the connecting parts to pass through to achieve a fixed connection with the ground. A bottom rubber pad 3 is provided at the bottom of the rectangular cylinder 102 to prevent the piston body 5 from making hard contact with the bottom of the hydraulic cylinder 1. The rectangular cylinder 102 needs to be filled with fluid, such as hydraulic oil, which is the key to achieving damping and vibration reduction.

[0031] The cover 2 is fixedly connected to the cylinder 1 by bolts 9. The specific structure of the cover 2 includes a pressing plate 201. The lower surface of the pressing plate 201 has an inner plate 202, which can be perfectly embedded in the rectangular cylinder 102. The outer side of the inner plate 202 has an outer groove 204 connected end to end. The inner plate 202 is provided with a rubber ring 8 in the outer groove 204 to form a rectangular sealing surface, which is used to prevent the fluid in the rectangular cylinder 102 from overflowing from the fit gap between the cover 2 and the rectangular cylinder 102. The part of the pressing plate 201 outside the inner plate 202 has a through hole 203. The top surface of the rectangular cylinder 102 has an internal thread hole 104 aligned with the through hole 203. There are several through holes 203 and internal thread holes 104, which are evenly arranged along the upper edge of the rectangular cylinder 102. The bolts 9 will pass through the through holes 203 and engage with the internal thread holes 104, thereby fixing the cover 2 to the upper open end of the cylinder 1.

[0032] The piston body 5 includes a rectangular plug plate 501 located inside a rectangular cylinder 102. The outer side of the rectangular plug plate 501 has a very small gap with the inner wall of the rectangular cylinder 102, allowing it to cooperate with the rectangular cylinder 102 to form a sliding pair. A sealing ring groove 502 is also provided on the outer side of the rectangular plug plate 501. A piston sealing ring 6 is provided within the sealing ring groove 502. The piston sealing ring 6 is pressed against the inner wall of the rectangular cylinder 102 by the rectangular plug plate 501, forming a rectangular sealing surface. Although the piston sealing ring 6 can slide up and down along the rectangular cylinder 102, hydraulic oil will not pass through the contact surface between the piston sealing ring 6 and the inner wall of the rectangular cylinder 102. A convection hole 505 penetrating the upper and lower surfaces is provided in the center of the rectangular plug plate 501. The diameter of the convection hole 505 is very small, resulting in very high resistance when hydraulic oil passes through it. The cover 2 has guide holes 205 penetrating the upper and lower surfaces. There are usually two guide holes 205. The inner plate 20... A top rubber pad 4 is fixedly connected to the lower surface of the piston 5 to prevent hard contact between the piston body 5 and the cover 2. The top rubber pad 4 has a clearance hole 401 aligned with the guide hole 205. A guide post 503 is fixedly connected to the upper surface of the rectangular plug plate 501. The number and position of the guide posts 503 correspond to the guide holes 205, and there are two of them. They are used to cooperate with the corresponding guide holes 205 to form a sliding pair. In fact, the cover 2 has a coaxial inner groove 206 on the inner wall of the guide hole 205. A plug rod sealing ring 7 is set in the inner groove 206 to form an annular sealing surface on the outside of the guide post 503 to prevent hydraulic oil from overflowing from the gap between the guide post 503 and the cover 2. A support plate 504 is fixedly connected to the upper end of the guide post 503 to directly contact the punch press base. A recessed hole 506, which is generally a threaded hole, is opened on the upper surface of the support plate 504 to cooperate with the threaded fastener, thereby fixing the punch press base and the support plate 504 together.

[0033] Working principle: In use, first fix the base plate 101 to the ground, and then fix the base of the heavy-duty punch press to the support plate 504. When the heavy-duty punch press vibrates during operation, the support plate 504 will transmit the vibration to the rectangular plug plate 501 through the guide column 503. The rectangular plug plate 501 is forced to float up and down inside the rectangular cylinder 102. Although the floating range is very small, the cross-sectional area of ​​the rectangular plug plate 501 is large, which will compress a large volume of hydraulic oil through the convection hole 505. Since the diameter of the convection hole 505 is very small, the hydraulic oil has great resistance when passing through the convection hole 505, generating a large friction, which will convert the kinetic energy of the liquid flow into heat energy, thereby consuming vibration energy and playing a role in vibration suppression.
