Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of press frame, more particularly, to a high-rigidity damping frame of servo press. BACKGROUND

[0002] In modern manufacturing industry, servo press is widely used in stamping forming processing of automobile parts, electronic components, hardware products and other fields due to its high precision, high response speed and flexible stamping characteristics. With the continuous improvement of the precision requirements of industrial production on workpieces, and the development of servo press towards large-scale and high-speed, the vibration problem in the working process of servo press is increasingly prominent, which becomes a key factor restricting the processing precision, service life and stability of the surrounding environment of the equipment.

[0003] At present, the servo press frames on the market mostly adopt single-structure damping design, which can be mainly divided into two categories. One is the impact-resistant frame for high-intensity impact, which uses high-rigidity materials or installs impact-resistant damping elements to cope with the instantaneous high-intensity impact load generated when stamping large workpieces. The other is the vibration-isolating frame for low-frequency vibration, which relies on flexible damping materials or low-frequency vibration isolation mechanisms to weaken the continuous low-frequency and slight vibration transmission generated when stamping small workpieces. However, for the frame with only impact-resistant function, the stiffness of the impact-resistant damping element is high, which can effectively buffer the instantaneous high-intensity impact, but has poor weakening ability for continuous low-frequency and slight vibration, resulting in that the vibration is easily transmitted to the ground and surrounding equipment when stamping small workpieces, which not only affects the stamping precision of the frame itself, but also interferes with the normal work of adjacent equipment, causing overall vibration and noise pollution in the workshop. For the frame with only vibration isolation function, the carrying capacity of the vibration isolation mechanism is low, and if it is used for stamping large workpieces, the instantaneous high-intensity impact load is easy to exceed the rated carrying range of the vibration isolation mechanism, resulting in damage of the vibration isolation element, deformation of the frame structure, and even equipment failure, which shortens the service life of the servo press. Therefore, when the servo press switches the stamping workpiece type according to the production demand, the existing damping frame is difficult to consider different vibration conditions. In view of this, we propose a high-rigidity damping frame of servo press. SUMMARY

[0014] Compared with the prior art, the present application has the following advantages:

[0015] 1、The shock-absorbing rack assembly of high rigidity material is designed, when in use, the work load and vibration of the press main body are transmitted to the shock-absorbing rack assembly below through the bottom connected base support table, the base support in the shock-absorbing rack assembly serves as a basic bearing structure, the semi-arc support arranged in the inner cavity is responsible for connecting the base support table and the base support, and preliminary load transmission and rigid support are realized; when the press main body stamps large workpieces to generate instantaneous high-strength impact load, the operator can adjust the control adjustment mechanism on the side wall of the base support to make the impact-resistant shock absorber in the shock-absorbing mechanism enter the working state, and the strong bearing and energy absorption capacity of the impact-resistant shock absorber are used to buffer and offset the high-strength impact vibration in the vertical direction; when the press main body stamps small workpieces to generate continuous low-frequency micro-amplitude vibration, the control adjustment mechanism is also switched to put the vibration isolation type shock absorber into work, and the vibration isolation type shock absorber is used to weaken the low-frequency vibration, so that the transmission of vibration to the base support and the ground is reduced, and finally the shock-absorbing mode is accurately matched according to different stamping conditions, the rigidity of the rack is ensured, the influence of vibration on the precision, service life of the equipment and the surrounding environment is effectively controlled, and the problem that the existing servo press adopts a single characteristic shock-absorbing mechanism and cannot consider different vibration conditions is solved.

[0016] 2、The present application is characterized in that the rolling groove is arranged in the inner wall of the wide arc-shaped support plate, and the guide block is arranged in the inner wall of the wide arc-shaped support plate, and the inner wall of the narrow arc-shaped support plate also has the same structure, which can accurately guide the rotation track by the rolling cooperation of the roller and the rolling groove when the shock absorber rotates to the vertical state and enters the working state, avoiding deviation and jamming, and the rigid positioning is realized by the insertion of the fixed block and the guide block, ensuring the stability and non-looseness of the shock absorber when bearing impact or vibration load; on the other hand, when the shock absorber rotates to the lying state and enters the idle state, the positioning is released by the separation of the fixed block and the guide block, and then the roller is separated from the rolling groove and is stored in the placing groove, avoiding the interference of the idle shock absorber components. Finally, the accuracy, stability and consistency of the switching action of the two shock absorbers under different stamping conditions are realized, the problems of track deviation, inaccurate positioning or idle component interference when switching the two shock absorbers are solved, and the working reliability of the overall shock rack is further ensured.

[0017] 3、The present application is characterized in that the arc of the wide arc-shaped support plate and the moving track of the roller when the impact-resistant shock absorber rotates are designed to intersect, when the impact-resistant shock absorber rotates from the vertical state to the lying state, the roller gradually separates from the rolling groove along the track, so that the impact-resistant shock absorber loses the close fitting relationship with the semicircular support, so that the vibration transmitted to the semicircular support cannot affect the impact-resistant shock absorber, avoiding unnecessary contact interference between components in the idle state; on the contrary, when the impact-resistant shock absorber rotates to the vertical working state, the roller and the rolling groove gradually form a squeezing state, and this gradual squeezing can gradually lift the semicircular support by the rotating action of the impact-resistant shock absorber, so that the impact-resistant shock absorber can form a supporting action on the semicircular support after rotating to the vertical state, and the supporting seat at the bottom of the semicircular support is separated from the inner cavity bottom of the base support, avoiding the direct transmission of the vibration of the semicircular support to the base support, and the supporting seat of the base support is still limited by the limiting column for horizontal displacement, and the vibration isolation type shock absorber is the same, so that when the two shock absorbers are switched according to the different vibrations of the servo press stamping different workpieces, they do not interfere with each other, and only one type of shock absorber is used to support and damp the semicircular support at a single time, avoiding the damage of the vibration with high impact force to the delicate vibration isolation type shock absorber, and solving the problems of mutual interference and damage of the delicate vibration isolation type shock absorber by high strength impact when switching different types of shock absorbers.

[0018] 4、The present application also designs the groove width of the rolling groove as an open structure from top to bottom, which on the one hand provides a smoother access for the roller when the shock absorber rotates to the vertical working state, even if there is a small trajectory deviation during rotation, the open slot can guide the roller to embed accurately in the rolling groove, ensuring the stable execution of the subsequent progressive extrusion and support seat lifting action; on the other hand, when the shock absorber rotates to the lying idle state, the open groove width can avoid the jamming or scraping of the roller and the rolling groove wall, so that the roller can quickly leave the rolling groove and smoothly enter the placing groove of the support seat, ensuring the smoothness of the shock absorber state switching, and ensuring that the two shock absorbers can realize stable action through the open structure of the rolling groove during switching, further improving the reliability and efficiency of the overall shock rack state switching.

[0019] 5、The present application designs upper and lower protruding guide strips on the guide block, which form a clamping groove channel between them, and the open entrance of the clamping groove channel provides a wide path for the anti-impact shock absorber top fixed insert block to enter, avoiding jamming; at the same time, the inner arc of the clamping groove channel and the rotating motion trajectory of the anti-impact shock absorber form a concentric circle structure, which can guide the fixed insert block to slide along the groove wall at all times when the shock absorber rotates, ensuring accurate access; when the shock absorber is completely rotated to the vertical working state, the fixed insert block is embedded in the clamping groove channel, and the abutting block on the inner wall of the guide block will be in close contact with the fixed insert block, limiting its displacement, preventing displacement of the fixed insert block caused by vibration, thereby further ensuring the stability of the connection between the shock absorber and the semi-arc support.

[0047] Further, the control and adjustment mechanism 34 is arranged on the side wall of the base support 31, and is used to control the working state of the impact-resistant damper 331 and the vibration isolation damper 332; when the press body 1 stamps large workpieces to generate high-intensity impact, the control and adjustment mechanism 34 can control the impact-resistant damper 331 to enter the working state, and when the press body 1 stamps small workpieces to generate continuous low-frequency vibration, the control and adjustment mechanism 34 can control the vibration isolation damper 332 to enter the working state.

[0048] The application designs a shock-absorbing frame assembly 3 with high rigidity material, when in use, the press main body 1 transmits the working load and vibration to the shock-absorbing frame assembly 3 below through the bottom connected base support table 2, the base support 31 in the shock-absorbing frame assembly 3 serves as a basic load bearing structure, the semi-arc support 32 arranged in the inner cavity is responsible for connecting the base support table 2 and the base support 31, and realizes preliminary load transmission and rigid support; when the press main body 1 stamps large workpieces to generate instantaneous high-strength impact load, the operator can adjust through the control adjusting mechanism 34 on the side wall of the base support 31, so that the impact-resistant shock absorber 331 in the shock-absorbing mechanism 33 enters the working state, and the strong load bearing and energy absorption capacity of the impact-resistant shock absorber 331 are used to buffer and offset the high-strength impact vibration in the vertical direction; when the press main body 1 stamps small workpieces to generate continuous low-frequency micro-amplitude vibration, the control adjusting mechanism 34 is also switched to put the vibration isolation shock absorber 332 into work, and the vibration isolation shock absorber 332 is used to weaken the low-frequency vibration, so that the vibration transmission to the base support 31 and the ground is reduced, and finally the shock-absorbing mode is accurately matched according to different stamping conditions, the overall rigidity of the frame is ensured, the influence of vibration on the equipment precision, service life and surrounding environment is effectively controlled, and the problem that the existing servo press with a single characteristic shock-absorbing mechanism cannot consider different vibration conditions is solved.

[0049] In the embodiment of the application, the mechanism groove 3101 is arranged on the outer side wall of the base support 31, a plurality of limiting columns 3102 and support protruding blocks 3103 are connected to the bottom of the inner cavity of the base support 31, a plurality of movable grooves one 3104 and a plurality of movable grooves two 3105 are formed in the top of the support protruding blocks 3103, and the plurality of movable grooves one 3104 and the plurality of movable grooves two 3105 are arranged in opposite directions. The semi-arc support 32 comprises a support plate 321, the top of the support plate 321 is connected to the bottom of the base support table 2, a plurality of wide arc-shaped support plates 322 are integrally formed on one side of the support plate 321, a plurality of narrow arc-shaped support plates 323 are integrally formed on the other side of the support plate 321, a support seat 324 is connected to the bottom of the wide arc-shaped support plate 322, and a structure symmetrical to the support seat 324 is connected to the bottom of the narrow arc-shaped support plate 323; a plurality of limiting holes 32401 are formed in the support seat 324 from top to bottom, the support seat 324 is sleeved on the limiting column 3102 through the limiting hole 32401, a spring 3106 is sleeved on the circumferential outer wall of the limiting column 3102, a limiting block 3107 is connected to the top of the limiting column 3102, and the spring 3106 is arranged between the support seat 324 and the limiting block 3107.

[0050] The half-arc support 32 is directly connected with the bottom of the base support table 2 through the top of the support plate 321, and when the press body 1 works and generates load and vibration, the base support table 2 transmits the force to the support plate 321; the wide-arc-shaped support plate 322 and the narrow-arc-shaped support plate 323 integrally formed on the two sides of the support plate 321 can disperse the concentrated load into uniformly distributed load along the arc surface by virtue of the anti-deformation characteristics of the arc structure, so as to avoid local stress concentration and cause the support to break or deform. The support seat 324 at the bottom of the wide-arc-shaped support plate 322 and the symmetric structure at the bottom of the narrow-arc-shaped support plate 323 are both sleeved on the limiting column 3102 in the inner cavity of the base support 31 through the limiting hole 32401, so as to limit the horizontal movement of the half-arc support 32 and only allow it to vertically ascend and descend along the limiting column 3102, thereby avoiding the horizontal deviation of the half-arc support 32 caused by the vibration of the press and ensuring the stable cooperation with the subsequent damping mechanism 33.

[0051] As another embodiment of the present application, the narrow-arc-shaped support plate 323 of one half-arc support 32 is arranged between the two narrow-arc-shaped support plates 323 of another half-arc support 32, so that the two half-arc supports 32 are arranged in a staggered state in the horizontal plane, which can greatly improve the space utilization, make the rack structure more compact, and ensure that the two half-arc supports 32 can relatively concentrate to support the press body 1.

[0052] As another embodiment of the present application, the damping mechanism 33 is movably arranged in the inner cavity of the half-arc support 32, and the two damping mechanisms 33 are arranged in a staggered manner; the damping mechanism 33 comprises a plurality of rotary rods 333 movably arranged in the inner cavity of the support protruding block 3103, one end of the rotary rod 333 extends into the mechanism groove 3101 in the side wall of the base support 31 and is connected with a gear 334; the side wall of the rotary rod 333 is connected with one end of an impact-resistant damper 331, a plurality of impact-resistant dampers 331 are arranged in a linear array, and the other end of the impact-resistant damper 331 is movably connected with the inner side wall of the wide-arc-shaped support plate 322; the side wall of the rotary rod 333 is connected with one end of a vibration isolation damper 332, a plurality of vibration isolation dampers 332 are arranged in a linear array, and the other end of the vibration isolation damper 332 is movably connected with the inner side wall of the narrow-arc-shaped support plate 323; the impact-resistant damper 331 is movably arranged in the active groove one 3104 through the rotary rod 333, and the vibration isolation damper 332 is movably arranged in the active groove two 3105 through the rotary rod 333; the impact-resistant damper 331 and the vibration isolation damper 332 are arranged in a right angle state in the vertical direction; the rotary rod 333 can drive the impact-resistant damper 331 to form a vertical state and the vibration isolation damper 332 to form a flat state, so that the half-arc support 32 and the support protruding block 3103 are connected through the impact-resistant damper 331, or drive the impact-resistant damper 331 to form a flat state and the vibration isolation damper 332 to form a vertical state, so that the half-arc support 32 and the support protruding block 3103 are connected through the vibration isolation damper 332.

[0053] The two damping mechanisms 33 are arranged in the cavity of the half-arc support 32 in a staggered manner to avoid mutual interference during operation and ensure comprehensive coverage of the vibration load; the core transmission component of the damping mechanism 33 is a rotating rod 333, which is rotatably installed in the cavity of the support protruding block 3103, one end of which extends to the mechanism groove 3101 of the side wall of the base support 31 and is connected with a gear 334 to provide a power connection point for subsequent state switching. The side wall of the rotating rod 333 is connected with an anti-impact damper 331 and a vibration isolation damper 332, respectively. When it is necessary to cope with the instantaneous high-intensity impact generated by the stamping of large workpieces by the press body 1, external power drives the rotating rod 333 to rotate through the gear 334, which drives the anti-impact damper 331 to rotate around the rotating rod 333 to a vertical state, so that its two ends stably connect the wide-arc-shaped support plate 322 of the half-arc support 32 and the support protruding block 3103, and simultaneously drives the vibration isolation damper 332 to a flat state to be disconnected. When it is necessary to cope with the continuous low-frequency and small-amplitude vibration generated by the stamping of small workpieces, the rotating rod 333 is reversely rotated, which drives the vibration isolation damper 332 to a vertical state to connect the narrow-arc-shaped support plate 323 and the support protruding block 3103, and the anti-impact damper 331 is in a flat state of idling, so as to realize the function of switching and adapting the damper according to different vibration conditions, and ensure that the vibration load transmitted by the half-arc support 32 can be accurately buffered and offset.

[0054] The anti-impact damper 331 and the vibration isolation damper 332 are designed to be arranged at a right angle in the vertical direction; when the control and adjustment mechanism 34 drives the rotating rod 333 to rotate, the precise state switching can be realized based on the right-angle arrangement relationship of the two: if it is necessary to cope with the instantaneous high-intensity impact generated by the stamping of large workpieces by the press body 1, the rotating rod 333 will drive the anti-impact damper 331 to rotate around the rotating shaft to a vertical state, so that its two ends are stably connected with the inner side wall of the wide-arc-shaped support plate 322 and the support protruding block 3103, respectively, at this time, the vibration isolation damper 332 arranged at a right angle will be synchronously rotated to a flat state, and is disconnected with the narrow-arc-shaped support plate 323, to avoid interfering with the buffering work of the anti-impact damper 331 on the high-intensity impact load; if it is necessary to cope with the continuous low-frequency and small-amplitude vibration generated by the stamping of small workpieces by the press body 1, the rotating rod 333 is reversely rotated, which drives the vibration isolation damper 332 to rotate to a vertical state, so that it is connected with the inner side wall of the narrow-arc-shaped support plate 323 and the support protruding block 3103 to weaken the transmission of low-frequency vibration, and the anti-impact damper 331 is rotated to a flat state, which is disconnected with the wide-arc-shaped support plate 322, to ensure that the vibration isolation damper 332 can efficiently play a vibration isolation role. This right-angle arrangement design not only provides a clear motion trajectory boundary for the state switching of the two dampers, avoiding structural interference during the switching process, but also ensures that only one damper is in a working state at the same time, realizing precise adaptation to different vibration conditions.

When the vibration isolation type shock absorber 332 switches state, the roller 33102 at the top of the vibration isolation type shock absorber 332 and the fixed embedded block 33101 will have the same cooperation and separation action with the rolling groove 32201, the guide clamping block 32202 and the corresponding placement groove of the narrow arc-shaped support plate 323, so as to realize the accurate switching and stable work of the two shock absorbers under different working conditions.

[0057] In the application, the anti-impact shock absorber 331 is provided with a fixed embedded block 33101 and a side wall rotating roller 33102 at the top, the top structure of the vibration isolation type shock absorber 332 is the same, the inner side wall of the wide arc-shaped support plate 322 is provided with a rolling groove 32201 and is provided with a guide clamping block 32202, the top of the support seat 324 is provided with a placement groove 32402 which is in communication with the rolling groove 32201, and the inner side wall of the narrow arc-shaped support plate 323 also has the same structure. When the anti-impact shock absorber 331 is driven to rotate to the vertical state by the rotating rod 333, the roller 33102 at the top of the anti-impact shock absorber 331 will first form a contact type rolling cooperation with the rolling groove 32201 of the wide arc-shaped support plate 322, stably slide along the rolling groove 32201 to guide the rotating track of the shock absorber, and after the anti-impact shock absorber 331 is completely vertical, the fixed embedded block 33101 is accurately inserted into the guide clamping block 32202 to realize stable insertion and ensure the connection reliability of the shock absorber during work; when the anti-impact shock absorber 331 rotates to the lying state, the fixed embedded block 33101 is first separated from the guide clamping block 32202, the roller 33102 is separated from the rolling groove 32201 and enters the placement groove 32402 of the support seat 324 to complete the storage. When the vibration isolation type shock absorber 332 switches state, the roller 33102 at the top of the vibration isolation type shock absorber 332 and the fixed embedded block 33101 will have the same cooperation and separation action with the rolling groove 32201, the guide clamping block 32202 and the corresponding placement groove of the narrow arc-shaped support plate 323, so as to realize the accurate switching and stable work of the two shock absorbers under different working conditions.

[0058] As another embodiment of the present application, the arc of the wide arc-shaped support plate 322 and the moving track of the roller 33102 of the anti-impact shock absorber 331 form an intersecting state, when the anti-impact shock absorber 331 rotates from the vertical state to the lying state, the roller 33102 can gradually form a separation state with the rolling groove 32201 of the inner side wall of the wide arc-shaped support plate 322, and vice versa, then gradually form a pressing state, the narrow arc-shaped support plate 323 and the vibration isolation shock absorber 332 are the same, the groove width of the rolling groove 32201 is in an open structure from top to bottom.

[0059] The present application designs the arc of the wide arc-shaped support plate 322 and the moving track of the roller 33102 of the anti-impact shock absorber 331 to form an intersecting state, when the anti-impact shock absorber 331 rotates from the vertical state to the lying state, the roller 33102 gradually separates from the rolling groove 32201 along the track, so that the anti-impact shock absorber 331 loses the close fitting relationship with the semi-arc support 32, so that the vibration transmitted to the semi-arc support 32 cannot affect the anti-impact shock absorber 331, avoiding unnecessary contact and interference between components in the idle state; on the contrary, when the anti-impact shock absorber 331 rotates to the vertical working state, the roller 33102 gradually forms a pressing state with the rolling groove 32201, this gradual pressing can gradually lift the semi-arc support 32 by the rotating action of the anti-impact shock absorber 331, so that after the anti-impact shock absorber 331 is rotated to the vertical state, a supporting effect on the semi-arc support 32 can be formed, and after the semi-arc support 32 is lifted, the supporting seat 324 at the bottom of the semi-arc support 32 is separated from the bottom of the inner cavity of the base support 31, avoiding the vibration of the semi-arc support 32 directly transmitted to the base support 31, and the supporting seat 324 of the base support 31 still forms a horizontal displacement restriction through the limiting column 3102, and the vibration isolation shock absorber 332 is the same, so that when the two shock absorbers are switched according to different vibrations generated by the servo press when stamping different workpieces, they do not interfere with each other, and only one mode of shock absorber is used to support and dampen the semi-arc support 32 at a single time, avoiding that the vibration with large impact force easily damages the relatively delicate vibration isolation shock absorber 332.

[0060] The present application also designs the groove width of the rolling groove 32201 as an open structure from top to bottom, which on the one hand provides a smoother access path for the roller 33102 when the shock absorber rotates to the vertical working state, and even if there is a small trajectory deviation during rotation, the open slot can guide the roller 33102 to accurately embed in the rolling groove 32201, ensuring the stable execution of the subsequent progressive extrusion and lifting action of the support seat 324; on the other hand, when the shock absorber rotates to the lying idle state, the open groove width can avoid the jamming or scraping of the roller 33102 and the groove wall of the rolling groove 32201, so that the roller 33102 can quickly escape from the rolling groove and smoothly enter the placing groove 32402 of the support seat 324, ensuring the smoothness of the state switching of the shock absorber, and ensuring that the two shock absorbers can realize stable action through the open structure of the rolling groove 32201 during switching, further improving the reliability and efficiency of the state switching of the overall shock rack.

[0061] As another embodiment of the present application, the guide block 32202 includes a plurality of upper protruding guide strips 32203 connected to the inner side wall of the wide arc-shaped support plate 322, and the guide block 32202 also includes a plurality of lower protruding guide strips 32204, the upper protruding guide strips 32203 and the lower protruding guide strips 32204 form a clamping groove channel 32205, the entrance of the clamping groove channel 32205 is an open structure, and the inner arc of the clamping groove channel 32205 and the rotating motion trajectory of the impact-resistant shock absorber 331 form a concentric circle structure; the inner side wall of the guide block 32202 is connected with a contact block 32206.

[0062] The present application designs the upper protruding guide strips 32203 and the lower protruding guide strips 32204 on the guide block 32202, and the upper protruding guide strips 32203 and the lower protruding guide strips 32204 form a clamping groove channel 32205, and the open entrance of the clamping groove channel 32205 provides an open path for the entrance of the fixed embedded block 33101 at the top of the impact-resistant shock absorber 331, avoiding jamming; at the same time, the inner arc of the clamping groove channel 32205 and the rotating motion trajectory of the impact-resistant shock absorber 331 form a concentric circle structure, which can guide the fixed embedded block 33101 to slide along the groove wall when the shock absorber rotates, ensuring accurate access; when the shock absorber is completely rotated to the vertical working state, the fixed embedded block 33101 is embedded in the clamping groove channel 32205, and the contact block 32206 of the inner side wall of the guide block 32202 will be in close contact with the fixed embedded block 33101, limiting its displacement, preventing displacement of the fixed embedded block 33101 caused by vibration, thereby further ensuring the stability of the connection between the shock absorber and the semi-arc support 32.

[0063] As another embodiment of the application, the control adjustment mechanism 34 comprises a screw linear movement mechanism arranged in the mechanism groove 3101. The screw linear movement mechanism is a structure that linearly moves the movement end of the screw rotation drive. The movement end of the screw linear movement mechanism is connected with a toothed plate 3401. The top of the screw of the screw linear movement mechanism is connected with a worm wheel 3402. The worm wheel 3402 is rotatably arranged on the inner wall of the mechanism groove 3101. The worm wheel 3402 is meshingly connected with the worm 3403. The two symmetrical side walls of the toothed plate 3401 are arranged with tooth openings of the same structure. The tooth openings of the toothed plate 3401 are meshingly connected with the gear 334. One end of the worm 3403 is movably penetrated through the side wall of the base support 31 and is connected with a hand wheel 3404. The operator rotates the hand wheel 3404 on the side wall of the base support 31 to drive the worm 3403 connected therewith to rotate on the inner wall of the mechanism groove 3101. Because the worm 3403 is meshingly connected with the worm wheel 3402 at the top of the screw of the screw linear movement mechanism, the rotation of the worm 3403 will drive the worm wheel 3402 and the screw to rotate synchronously. Based on the conventional working logic of the screw linear movement mechanism, the rotation of the screw will drive the toothed plate 3401 connected with the movement end to ascend and descend in the vertical direction in the mechanism groove 3101. Because the two symmetrical side walls of the toothed plate 3401 are provided with tooth openings and are meshingly connected with the gear 334 at one end of the rotating rod 333 of the damping mechanism 33, the ascending and descending of the toothed plate 3401 will drive the gear 334 and the rotating rod 333 to rotate, and finally the rotating rod 333 is rotated to switch the working state of the impact-resistant damper 331 and the vibration isolation damper 332, so as to adapt to the damping requirements of the press under different stamping working conditions.

[0064] When the operator rotates the hand wheel 3404 to drive the worm 3403, the worm wheel 3402, and the screw to rotate, the toothed plate 3401 is ascended and descended, and the impact-resistant damper 331 or the vibration isolation damper 332 is switched to the target working state through the gear 334 and the rotating rod 333, even if the press works to generate vibration load, the force transmitted to the rotating rod 333 and the gear 334 will be transmitted to the worm wheel 3402 through the toothed plate 3401. Because the worm wheel 3402 cannot reversely drive the worm 3403 to rotate, the transmission chain of the entire control adjustment mechanism 34 will remain fixed and will not cause the state of the damper to deviate due to vibration. It is ensured that the currently working damper is always in a stable vertical support state, and the idle damper remains in a flat storage state. At the same time, the worm and gear transmission itself has the characteristics of deceleration and force amplification. When the operator rotates the hand wheel 3404, it is not necessary to apply excessive force. The driving force can be amplified through the transmission ratio of the worm and gear to drive the screw, the toothed plate 3401, the gear 334, and the rotating rod 333 to complete the state switching of the damper, which realizes a relatively labor-saving adjustment operation and reduces the labor cost and operation difficulty during working condition switching.

[0065] Working principle: the embodiment provides a high-rigidity damping frame of a servo press, when in use, the press body 1 is connected with the base support table 2 through the bottom, and the load and vibration generated during stamping workpieces are transmitted to the damping frame assembly 3 below; the base support 31 serves as a basic load-bearing structure, the semi-arc support 32 in the inner cavity is connected with the base support table 2 through the support plate 321, and the load transmission and rigid support are preliminarily realized, and the semi-arc support 32 bottom support seat 324 is sleeved on the limiting column 3102 through the limiting hole 32401, and only vertical displacement is allowed, and horizontal deviation is limited; the operator rotates the hand wheel 3404 on the side wall of the base support 31 according to the type of the stamped workpieces, drives the worm 3403 to rotate, the worm 3403 meshes with the worm wheel 3402 to drive the screw linear movement mechanism to operate, so that the toothed plate 3401 vertically lifts, and then the toothed plate 3401 meshes with the gear 334 to drive the rotating rod 333 to rotate; if a large workpiece is stamped and a high-intensity impact is generated, the rotating rod 333 drives the anti-impact shock absorber 331 to rotate around the rotating shaft to the vertical state, and in the process, the top roller 33102 rolls along the rolling groove 32201 of the wide-arc-shaped support plate 322 to guide the track, and until the fixed embedded block 33101 is inserted and fixed with the clamping groove channel 32205 of the guide clamping block 32202, at this time, the anti-impact shock absorber 331 is connected with the wide-arc-shaped support plate 322 and the support protruding block 3103 at both ends, and the vertical impact is buffered by virtue of the strong bearing and energy absorption capacity; at the same time, the vibration isolation shock absorber 332 is in a flat state with the rotating rod 333, the roller 33102 is separated from the rolling groove of the narrow-arc-shaped support plate 323 and is stored in the placing groove 32402, so as to avoid interference; if a small workpiece is stamped and a low-frequency micro-vibration is generated, the hand wheel 3404 is reversely rotated, the rotating rod 333 drives the vibration isolation shock absorber 332 to the vertical state, and the vibration isolation shock absorber 332 is fixed by cooperating with the rolling groove of the narrow-arc-shaped support plate 323 and the guide clamping block, so as to weaken the low-frequency vibration transmission; the anti-impact shock absorber 331 is in a flat state and is stored. When the two shock absorbers are switched, because the wide-arc-shaped support plate and the narrow-arc-shaped support plate are intersected with the moving track of the roller 33102, the rolling groove 32201 is wide at the top and narrow at the bottom, the state switching is smooth without jamming, the semi-arc support 32 is lifted with the vertical support of the shock absorber, the support seat 324 is separated from the inner cavity of the base support 31, the vibration is directly transmitted, and finally the precise damping according to different working conditions is realized, and the equipment precision and the surrounding environment stability are ensured.
