The mounting base is movably connected to the base, and the vibration damping components for providing vibration damping support to the press are installed between them. The base is located at the bottom of the mounting base and is used to install the vibration damping components, while the top of the mounting base is used to install the press.

Description

Technical Field

[0001] This invention relates to the field of press technology, specifically to a shock-absorbing base for a press. Background Technology

[0002] As an important forming equipment in modern industry, presses are widely used in processes such as stamping, forging, and molding. During their operation, especially during the stamping or forging process, they generate severe impacts and vibrations. These vibrations not only reduce processing accuracy and affect product quality, but also cause fatigue damage to the press's structural components, molds, and hydraulic systems, shortening the equipment's lifespan. Furthermore, the strong vibrations are transmitted through the equipment base to the work area, causing environmental noise pollution and even affecting the normal operation of other precision equipment and the structural safety of the factory building.

[0003] To effectively suppress harmful vibrations during press operation, a vibration damping base is typically installed between the press and its foundation. However, traditional vibration damping bases often fail to ensure that the multiple damping elements (such as shock absorbers) are subjected to completely uniform stress during equipment operation. Some shock absorbers may overload and fail prematurely, while others may not function effectively, resulting in poor overall damping performance and affecting equipment stability. After long-term operation, this can easily lead to tilting or swaying. Furthermore, shock absorbers are consumable parts, and their performance gradually deteriorates after prolonged exposure to impact loads, requiring regular maintenance or replacement. Currently, replacing shock absorbers is typically a very cumbersome process. It often requires lifting the entire press or using large jacks to lift the massive press body to access and remove the bottom shock absorbers. This is not only risky and time-consuming, but also requires specialized lifting equipment and prolonged downtime, severely impacting production efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a shock-absorbing base for presses, which has the advantages of uniform shock absorption, improved shock absorption effect, and easy and quick replacement of damaged shock absorbers. It solves the problems of current shock-absorbing bases at the bottom of presses, which are difficult to evenly distribute vibration force, resulting in poor shock absorption effect, and the high risk, time and labor-intensive operation of replacing damaged shock absorbers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shock-absorbing base for a press, comprising a base, a mounting base, and a shock-absorbing component. The mounting base is movably connected to the base, and a shock-absorbing component for providing shock-absorbing support for the press is installed between them. The base is located at the bottom of the mounting base and is used to install the shock-absorbing component, while the top of the mounting base is used to install the press. When the press vibrates during operation, the shock-absorbing component on the base provides buffering and shock absorption.

[0006] The base has mounting slots at all four corners. The shock absorber includes a shock absorber movably connected in the mounting slot. A connecting rod is rotatably connected to the output end of the shock absorber. The mounting slots at the four corners of the base are equally spaced, and each mounting slot is equipped with a shock absorber. This effectively and evenly buffers and reduces the vibration force generated by the press above, ensuring the shock absorption effect and stability.

[0007] There are connecting holes at all four corner positions on the mounting base. The connecting rod is threaded into the connecting hole, and the diameter of the connecting rod matches the diameter of the connecting hole. The connection between the shock absorber and the mounting base is achieved by threading the connecting rod into the connecting hole.

[0008] When using this press's vibration-damping base, a vibration damper is installed in the mounting groove and locked in place by a retaining device. The connecting rod on the output end of the vibration damper is threaded into the corresponding connecting hole on the mounting base. Hydraulic rods are movably connected to both ends of the connecting groove on the base. One end of the hydraulic rod is rotatably connected to one end in the connecting groove, while the other end is rotatably connected to the corresponding position on the bottom of the mounting base. The bottom of the press is then mounted on the mounting base, and screws are threaded into the mounting holes on the bottom of the press, thus fixing the press to the mounting base. The vibrations generated during press operation are evenly buffered and damped by the vibration dampers installed at the four corners of the base. Over time, the vibration damping effect of the vibration dampers is enhanced. When the shock absorber needs to be replaced due to a drop in pressure, the hydraulic rod operates, and when the output end outputs outward, it lifts the mounting base and the press above it. Under the force of the connection between the connecting hole and the threaded connection of the connecting rod, the shock absorber is driven to rise. At this time, it slides on the side of the retaining rod through the limiting groove, switching the upper magnetic block to the lower magnetic block. Using the magnetic repulsion between the lower magnetic block and the magnetic button, the retaining rod moves backward and disengages from the limiting groove. At this time, the mounting base can drive the shock absorber to completely detach from the base. Then, by rotating the connecting rod, the connecting rod is separated from the connecting hole, and the corresponding shock absorber is removed and replaced with a new shock absorber. The above steps are repeated in reverse until the shock absorber enters the corresponding mounting groove. After the upper magnetic block and the magnetic button in the limiting groove are aligned, the magnetic attraction force fixes the retaining component between the shock absorber and the base.

[0009] As a further improvement to the above solution, a retaining member is movably connected to the side of the base. The retaining member includes a sleeve hole that penetrates the mounting groove on the side of the base, and a retaining rod is movably sleeved in the sleeve hole.

[0010] The shock absorber has a limiting groove on its side, and the front end of the retaining rod is movably connected in the limiting groove.

[0011] With the above technical solution, when the retaining rod moves into the mounting groove in the sleeve hole, the front end of the retaining rod is inserted into the limiting groove, thereby limiting the position of the shock absorber and preventing the shock absorber from falling out of the mounting groove.

[0012] As a further improvement to the above scheme, an upper magnetic block and a lower magnetic block are fixed in the limiting groove, and a magnetic button is fixed at the front end of the fixing rod. The magnetic button is opposite to the upper magnetic block and the lower magnetic block respectively through displacement changes.

[0013] With the above technical solution, when the bottom of the shock absorber is completely attached to the bottom of the mounting groove, the upper magnetic block and the magnetic button are aligned. At this time, the magnetic attraction force causes the magnetic button to move the retaining rod into the mounting groove until the magnetic button and the upper magnetic block are attracted and fixed. When the shock absorber moves upward, the limiting groove moves to the side of the retaining rod until the lower magnetic block and the magnetic button are aligned. Then, the magnetic repulsion force causes the magnetic button to move the retaining rod in the opposite direction and disengage from the limiting groove, thus allowing the shock absorber to be removed from the mounting groove.

[0014] As a further improvement to the above solution, multiple support components are distributed on the base. The support components include connecting grooves opened on the base and located between the mounting grooves, and two hydraulic rods are arranged opposite each other in the connecting grooves.

[0015] Both ends of the hydraulic rod are equipped with rotating blocks, with one rotating block rotatably connected to the connecting groove, and the other rotating block rotatably connected to the corresponding position at the bottom of the mounting base.

[0016] With the above technical solution, the four sides above the base are provided with connecting slots, and the hydraulic rods in the multiple connecting slots operate synchronously. During operation, the output end of the hydraulic rod outputs outward synchronously and is turned by the rotating block to lift the mounting base.

[0017] It should be further explained that at the moment the mounting base is lifted, the force exerted by the threaded connection between the connecting rod and the connecting hole will cause the shock absorber to change its position upward. Through this displacement distance, the upper magnetic block in the limiting groove will disengage from the magnetic button at the front end of the retaining rod until the lower magnetic block aligns with the magnetic button. Then, the magnetic repulsion force will cause the magnetic button to move the retaining rod outward and disengage from the limiting groove, thereby allowing the shock absorber to quickly separate from the base for easy replacement later.

[0018] As a further improvement to the above solution, multiple mounting holes are provided on the mounting base.

[0019] With the above technical solution, when the press is installed above the mounting base, the press is fixed above the mounting base by passing screws through the mounting holes of the press and threading them into the mounting holes.

[0020] It should be further explained that the position of the mounting holes is specifically set according to the multiple mounting holes of the press to ensure that when the press is placed on the mounting base, the mounting holes are aligned with the mounting holes of the press, thus facilitating fixation.

[0021] As a further improvement to the above solution, multiple stabilizing sleeve rods are fixedly distributed at the bottom of the mounting base, and multiple stabilizing holes are distributed on the base, with the stabilizing sleeve rods movably sleeved in the stabilizing holes.

[0022] Through the above technical solution, when the mounting base moves up and down, it moves within the stabilizing hole through the stabilizing sleeve rod, ensuring the stability between the mounting base and the base and the precise alignment effect during installation.

[0023] Compared with the prior art, the present invention provides a shock-absorbing base for a press, which has the following advantages: 1. The press uses a shock-absorbing base, which has multiple mounting slots evenly distributed at the four corners of the base, and shock absorbers are installed in each mounting slot. The shock absorbers are threadedly connected to the connecting holes of the mounting base through the connecting rod installed at the output end. When the press operates above the mounting base, the vibration generated can evenly drive the connecting rod to produce a change in height displacement, so that the output end of the shock absorber can be evenly stressed, effectively improving the shock absorption effect.

[0024] 2. This press uses a shock-absorbing base. Supporting components are evenly installed on the base. The hydraulic rod operates while simultaneously rotating, lifting the mounting base. At the same time, the force from the threaded connection between the connecting rod and the connecting hole causes the shock absorber to move upwards. This results in a height displacement change in the limiting groove at the corresponding end of the retaining rod, replacing the upper magnetic block attracted by the magnetic button with a lower magnetic block with magnetic repulsion. This causes the retaining rod to displace in the opposite direction, separating the mounting base and the shock absorber from the base. This allows for quick disassembly and replacement of the shock absorber. The hydraulic rod then reverses its operation, causing the mounting base to move downwards, allowing the shock absorber to be reinstalled in the mounting groove and secured by the retaining components. This achieves the effect of rapid disassembly and replacement of the shock absorber. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0028] Please see Figure 1 - Figure 4 As shown, the shock-absorbing base for the press proposed in this embodiment includes a base 1, a mounting base 2, and a shock absorber 3. The mounting base 2 is movably connected to the base 1, and the shock absorber 3 for providing shock-absorbing support for the press is installed between them. The base 1 is located at the bottom of the mounting base 2 and is used to install the shock absorber 3, while the top of the mounting base 2 is used to install the press. When the press vibrates during operation, the shock absorber 3 on the base 1 provides buffering and shock absorption.

[0029] The base 1 has mounting slots 11 at each of the four corner positions. The shock absorber 3 includes a shock absorber 301 movably connected in the mounting slot 11. A connecting rod 302 is rotatably connected to the output end of the shock absorber 301. The mounting slots 11 at the four corner positions of the base 1 are equally spaced, and each mounting slot 11 is equipped with a shock absorber 301. This can effectively and evenly buffer and reduce the vibration force generated by the press above, ensuring the shock absorption effect and stability.

[0030] There are connecting holes 201 at the four corner positions of the mounting base 2. The connecting rod 302 is threaded into the connecting hole 201. The diameter of the connecting rod 302 matches the diameter of the connecting hole 201. By connecting the connecting rod 302 into the connecting hole 201, the shock absorber 301 is connected and fixed to the mounting base 2.

[0031] The working principle of the shock-absorbing base for the press proposed in this embodiment is as follows: During use, a shock absorber 301 is installed in the mounting groove 11 and locked in place by the retaining member 12. Simultaneously, the connecting rod 302 on the output end of the shock absorber 301 is threaded into the corresponding connecting hole 201 on the mounting base 2. Hydraulic rods 132 are movably connected to both ends of the connecting groove 131 on the base 1. One end of the hydraulic rod 132 has a rotating block 133 rotatably connected to one end of the connecting groove 131, while the other end has a rotating block 133 rotatably connected to the corresponding position on the bottom of the mounting base 2. The bottom of the press is then mounted on the mounting base 2, and screws are threaded through the mounting holes on the bottom of the press and threaded into the mounting holes 202, thus fixing the press to the mounting base 2. The vibration generated during the operation of the press is evenly buffered and damped by the shock absorbers 301 installed at the four angular positions of the base 1. However, over time, as the damping effect of the shock absorbers 301 decreases, it is necessary to adjust the damping mechanism. When device 301 is replaced, the hydraulic rod 132 operates, and when the output end outputs outward, it lifts the mounting base 2 and the press above it. Under the force of the threaded connection between the connecting hole 201 and the connecting rod 302, the shock absorber 301 is driven to rise. At this time, it slides on the side of the retaining rod 122 through the limiting groove 303, switching the upper magnetic block 304 to the lower magnetic block 305. Utilizing the magnetic repulsion between the lower magnetic block 305 and the magnetic button 123, the retaining rod 122 is moved backward and disengaged from the limiting groove 303. Mounting base 2 can completely detach the shock absorber 301 from the base 1. Then, by rotating the connecting rod 302, the connecting rod 302 is separated from the connecting hole 201. After removing the corresponding shock absorber 301, a new shock absorber 301 is replaced. The above steps are repeated in reverse until the shock absorber 301 enters the corresponding mounting groove 11. After the upper magnetic block 304 in the limiting groove 303 is aligned with the magnetic button 123, the retaining member 12 fixes the shock absorber 301 to the base 1 by magnetic attraction. Example 2

[0032] Please see Figure 1 - Figure 4 As shown, the shock-absorbing base for the press proposed in this embodiment, based on the first embodiment, further includes a retaining member 12 movably connected to the side of the base 1. The retaining member 12 includes a sleeve hole 121 that penetrates the mounting groove 11 on the side of the base 1, and a retaining rod 122 is movably sleeved in the sleeve hole 121.

[0033] The shock absorber 301 has a limiting groove 303 on its side, and the front end of the retaining rod 122 is movably connected in the limiting groove 303.

[0034] More specifically, when the retaining rod 122 moves into the mounting groove 11 in the sleeve hole 121, the front end of the retaining rod 122 is inserted into the limiting groove 303, thereby limiting the position of the shock absorber 301 and preventing the shock absorber 301 from falling out of the mounting groove 11.

[0035] Furthermore, an upper magnetic block 304 and a lower magnetic block 305 are fixed inside the limiting groove 303, and a magnetic button 123 is fixed at the front end of the fixing rod 122. The magnetic button 123 is opposite to the upper magnetic block 304 and the lower magnetic block 305 respectively through displacement changes.

[0036] More specifically, when the bottom of the shock absorber 301 is completely attached to the bottom of the mounting groove 11, the upper magnetic block 304 is aligned with the magnetic button 123. At this time, the magnetic attraction force causes the magnetic button 123 to move the retaining rod 122 into the mounting groove 11 until the magnetic button 123 is attracted and fixed to the upper magnetic block 304. When the shock absorber 301 undergoes an upward displacement, the limiting groove 303 is displaced on the side of the retaining rod 122 until the lower magnetic block 305 is aligned with the magnetic button 123. Then, the magnetic repulsion force causes the magnetic button 123 to move the retaining rod 122 in the opposite direction and disengage from the limiting groove 303, thereby enabling the shock absorber 301 to be removed from the mounting groove 11.

[0037] Furthermore, a plurality of support members 13 are distributed on the base 1. The support member 13 includes a connecting groove 131 opened on the base 1 and located between the mounting grooves 11. Two hydraulic rods 132 are arranged opposite to each other in the connecting groove 131.

[0038] Both ends of the hydraulic rod 132 are provided with rotating blocks 133, and one end of the rotating block 133 is rotatably connected in the connecting groove 131, while the other end of the rotating block 133 is rotatably connected to the corresponding position at the bottom of the mounting base 2.

[0039] More specifically, the four sides above the base 1 and the adjacent mounting slots 11 are provided with connecting slots 131, and the hydraulic rods 132 in the multiple connecting slots 131 operate synchronously. When operating, the output end of the hydraulic rod 132 outputs outward synchronously and is turned by the rotating block 133 to lift the mounting base 2.

[0040] It should be further explained that at the moment the mounting base 2 is lifted, the force of the threaded connection between the connecting rod 302 and the connecting hole 201 will cause the shock absorber 301 to change its position upward. Through this displacement distance, the upper magnetic block 304 in the limiting groove 303 will disengage upward from the magnetic button 123 at the front end of the retaining rod 122 until the lower magnetic block 305 is aligned with the magnetic button 123. Then, the magnetic repulsion force will cause the magnetic button 123 to move the retaining rod 122 outward and disengage from the limiting groove 303, so that the shock absorber 301 can be quickly separated from the base 1 for easy replacement later.

[0041] Furthermore, the mounting base 2 has multiple mounting holes 202 distributed on it.

[0042] More specifically, when the press is installed above the mounting base 2, the press is fixed above the mounting base 2 by passing screws through the mounting holes of the press and threading them into the mounting holes 202.

[0043] It should be further explained that the position of the mounting hole 202 is specifically set according to the corresponding mounting hole position of the press, so as to ensure that when the press is placed on the mounting base 2, the mounting hole 202 is opposite to the mounting hole position of the press, thus facilitating fixation.

[0044] Furthermore, multiple stabilizing sleeves 203 are fixedly distributed at the bottom of the mounting base 2, while multiple stabilizing holes 14 are distributed on the base 1, and the stabilizing sleeves 203 are movably sleeved in the stabilizing holes 14.

[0045] More specifically, when the mounting base 2 moves up and down, it moves within the stabilizing hole 14 via the stabilizing sleeve 203, ensuring the stability between the mounting base 2 and the base 1 and the precise alignment effect during installation.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
