Description

Technical Field

[0001] This invention relates to the field of press technology, and in particular to a servo press and a vibration reduction method. Background Technology

[0002] General-purpose servo presses are widely used in industries such as home appliances, digital products, and automobiles due to their low manufacturing cost, short installation and commissioning cycle, and high production efficiency. Due to limitations such as installation and commissioning cycle and factory space, general-purpose servo presses generally adopt an integrated design of the machine body and electrical cabinet, with the electrical cabinet placed directly on the machine body.

[0003] Currently, a vibration damping base is usually installed at the bottom of the electrical cabinet. The vibration damping base is usually a wire rope vibration damping structure, which contains several wire rope vibration dampers arranged in a row. The wire rope vibration dampers perform vibration damping operation for the electrical cabinet to ensure the stability and reliability of the electrical components of the electrical cabinet. However, in existing electrical cabinets, wire rope vibration dampers are usually installed between the bottom of the cabinet and the foundation platform. The rigidity of the wire rope vibration damper is fixed, and it is easy to have a hard impact with the bottom under large impact conditions, resulting in the direct transmission of impact force and poor vibration damping effect. In addition, most existing electrical cabinets use rigid connection methods for lateral connection of wire rope vibration dampers and other vibration damping structures. When the equipment is displaced or torn, the lateral vibration dampers are prone to failure or tearing of the cabinet shell due to excessive shear force. Summary of the Invention

[0004] To address the technical problems in the prior art where existing electrical cabinet vibration reduction structures have poor vibration reduction effects and are susceptible to failure or tearing of the cabinet shell due to shear forces, this invention provides a servo press and a vibration reduction method.

[0005] The technical solution of this invention is as follows: This invention provides a servo press, including an electrical cabinet and a press body mounted on a base platform. The bottom of the electrical cabinet is fixedly connected to the base platform via a vibration damping base. Side vibration damping components are installed on the sides and back of the electrical cabinet, and these components are fixedly connected to the press body via connecting beams. The vibration damping base includes a bottom plate and a top plate. The bottom plate is fixedly mounted on the base platform, and the top plate is fixedly mounted on the bottom of the electrical cabinet. Several first wire rope vibration dampers are fixedly installed between the bottom plate and the top plate, and a secondary vibration damping unit is fixedly installed on the bottom plate. This composite layout of multi-stage bottom vibration damping and side vibration damping completely isolates the electrical cabinet from the base platform, preventing the upward transmission of ground vibrations. The first wire rope vibration dampers provide buffering and vibration isolation under normal operating conditions, forming a composite vibration damping system with segmented stiffness variations in conjunction with the secondary vibration damping unit, balancing gentle vibration isolation for small vibrations with strong protection against large impacts. The side vibration damping components are arranged bidirectionally on the sides and back to absorb the lateral swaying and torsional vibrations of the cabinet, providing comprehensive overall vibration damping coverage and significantly improving the stability and safety of the electrical cabinet under strong vibration conditions of the press.

[0006] Preferably, the height of the secondary vibration damping unit is lower than that of the first wire rope vibration damper. The height difference arrangement realizes the graded triggering working mechanism. During normal small vibrations, only the first wire rope vibration damper participates in the work, ensuring that the vibration isolation is gentle and not harsh. When the impact is too large and the top plate is pressed down to the limit position, the secondary vibration damping unit is contacted, and the high stiffness buffer mode is automatically switched. This avoids the redundant participation of the secondary vibration damping unit under normal conditions, which affects the vibration isolation effect, and can provide strong support at the moment of strong impact, effectively preventing hard bottom impact from damaging the cabinet.

[0007] Preferably, the secondary vibration reduction unit is a polyurethane damping block or a disc spring assembly. The polyurethane damping block has high damping and gentle buffering, while the disc spring assembly has strong load-bearing capacity and stable stiffness. Both can provide nonlinear stiffness support according to the impact intensity, quickly absorb the remaining impact energy under large impact conditions, avoid the impact force from being directly transmitted to the internal components of the electrical cabinet, protect the electrical components from damage by strong vibration, and at the same time have a durable structure and low maintenance cost.

[0008] Preferably, the first wire rope vibration damper is provided in several rows and is arranged in a crisscross pattern on the surface of the base plate. The multiple rows of staggered arrangement make the bottom vibration damping force uniform, fully cover the cabinet support area, and avoid local stress concentration. The horizontal and vertical staggered arrangement can simultaneously isolate horizontal swaying vibrations in multiple directions, greatly improve the overall vibration isolation effect at the bottom, and ensure the stability of the cabinet in complex vibration environment.

[0009] Preferably, the side vibration damping assembly includes a second wire rope vibration damper and a slide rail. The slide rail is vertically fixed to the outer wall of the electrical cabinet. One end of the second wire rope vibration damper is fixedly connected to the press body via a connecting beam, and the other end of the second wire rope vibration damper is fixedly connected to the slider inside the slide rail via a ball joint connector. This flexible side vibration damping structure, using a slide rail and slider with a ball joint connection, allows the slider to slide freely vertically along the slide rail when the electrical cabinet experiences horizontal displacement or torsion, without generating additional shearing or pulling forces, thus preventing tearing damage at the connection between the vibration damper and the cabinet. The second wire rope vibration damper can freely extend and retract to absorb amplitude, and the ball joint connector allows for small-angle deflection of the connection point, adapting to the electrical cabinet's follow-up displacement and slight torsion conditions, significantly improving the reliability and service life of the side vibration damping.

[0010] Preferably, the second wire rope vibration isolator is arranged laterally, and both ends of the second wire rope vibration isolator are fixedly connected to connecting plates. The connecting plates have an L-shaped structure, and several reinforcing ribs are fixedly installed inside the connecting plates. The lateral arrangement of the second wire rope vibration isolator is more in line with the lateral vibration reduction force direction of the electrical cabinet. The L-shaped connecting plates are firmly installed and have a large bearing area. The internal reinforcing ribs significantly improve the structural rigidity of the connecting plates, prevent deformation and cracking due to long-term vibration and impact, and ensure that the connection of the second wire rope vibration isolator is stable and reliable.

[0011] Preferably, a rubber bushing is provided at the connection between the ball joint connector and the slider. The rubber bushing can further absorb high-frequency micro-amplitude vibration, buffer the impact stress at the connection point, compensate for assembly coaxiality errors, reduce rigid friction and wear, reduce operating noise, make the ball joint rotate more smoothly and gently, and extend the overall service life of the lateral vibration damping assembly.

[0012] Preferably, the press body is located on the back side of the electrical cabinet, and adjacent electrical cabinets are fixedly connected by a protective plate. A hollow rubber strip is provided between the electrical cabinet and the protective plate. The protective plate forms an overall protection for multiple electrical cabinets, and the hollow rubber strip flexibly isolates the electrical cabinet and the protective plate to avoid vibration and noise caused by rigid contact collision. At the same time, it absorbs the vibration transmitted between electrical cabinets, ensuring that the operation of a single electrical cabinet does not interfere with each other, and improving the overall stability of the electrical cabinet group.

[0013] A vibration reduction method includes: an electrical cabinet is isolated from the foundation platform by a vibration-damping base; a first wire rope vibration damper operates at low frequency and small amplitude to achieve foundation vibration isolation; and side vibration damping components absorb vibrations from the side walls of the electrical cabinet. When the press body generates a high-frequency, large impact that exceeds the stiffness of the first wire rope vibration damper, the top plate contacts a secondary vibration damping unit, achieving a nonlinear increase in stiffness. Under normal operating conditions, the first wire rope vibration damper provides efficient and gentle vibration isolation, ensuring stable operation of the electrical cabinet. During high-frequency, large impacts, the secondary vibration damping unit is automatically triggered, achieving a step-wise increase in stiffness, rapidly absorbing strong impact energy, preventing hard impacts to the bottom, effectively protecting the electrical cabinet structure and internal precision components, and significantly improving the equipment's impact resistance and reliability.

[0014] Preferably, when the press body generates low-frequency, large-amplitude vibrations or slight torsion around its axis, the side wall of the electrical cabinet will undergo a follow-up displacement. The extension and retraction of the second wire rope vibration damper absorbs the amplitude, the slider slides within the slide rail, and the ball joint connector allows the connection point to rotate at a small angle. The lateral flexible vibration damping system can adapt to the large-amplitude oscillations and slight torsional movements of the electrical cabinet. By releasing displacement stress through extension, sliding, and rotation, it avoids the lateral vibration damper from being subjected to excessive shear force, which could lead to failure or damage to the cabinet. This achieves all-round flexible buffering and absorption of lateral and torsional vibrations, further improving the safety and stability of the electrical cabinet under complex and harsh vibration conditions.

[0015] As can be seen from the above technical solutions, the advantages of the present invention are: 1. A composite layout of bottom multi-stage vibration damping and side vibration damping is adopted. The bottom vibration damping base completely isolates the electrical cabinet from the foundation platform, blocking the upward transmission of ground vibration. The first wire rope vibration damper is responsible for buffering and vibration isolation under normal working conditions. Together with the second-stage vibration damping unit, it forms a composite vibration damping system with segmented stiffness variation, which takes into account both gentle vibration isolation for small vibrations and strong protection against large impacts. Side vibration damping components are arranged bidirectionally on the sides and back to absorb the lateral sway and torsional vibration of the cabinet. The overall vibration damping coverage is comprehensive, which greatly improves the stability and safety of the electrical cabinet under the strong vibration conditions of the press.

[0016] 2. A flexible lateral vibration damping structure with a sliding rail slider and ball joint connection is adopted. When the electrical cabinet undergoes horizontal displacement or torsion, the slider can slide freely vertically along the sliding rail without generating additional shearing force, thus preventing tearing and damage at the connection between the vibration damper and the cabinet from the source. The second wire rope vibration damper can freely extend and retract to absorb the amplitude, and the ball joint connection allows for small-angle deflection of the connection point, adapting to the electrical cabinet's follow-up displacement and slight torsion conditions, greatly improving the reliability and service life of lateral vibration damping.

[0017] 3. Under normal operating conditions, the first wire rope vibration damper achieves efficient and gentle vibration isolation, ensuring stable operation of the electrical cabinet. During high-frequency and large-impact events, the secondary vibration damping unit is automatically triggered to achieve a step-wise increase in stiffness, quickly absorb strong impact energy, prevent hard impacts, effectively protect the electrical cabinet structure and internal precision components, and significantly improve the equipment's impact resistance and reliability. The lateral flexible vibration damping system can adapt to the electrical cabinet's large-amplitude swaying and slight torsional motion. Through the triple degrees of freedom of extension, sliding, and rotation, it releases displacement stress, preventing the lateral vibration damper from being subjected to excessive shear force, which could lead to failure or damage to the cabinet. This achieves all-round flexible buffering and absorption of lateral and torsional vibrations, further improving the safety and stability of the electrical cabinet under complex and harsh vibration conditions.

[0020] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Example 1 In a typical embodiment of the present invention, such as Figures 1-5 As shown, a servo press is proposed, including: a base platform 1, an electrical cabinet 2, a vibration damping base 3, side vibration damping components 4, a connecting beam 7, and a press body 8. The electrical cabinet 2 and the press body 8 are both mounted on the base platform 1. The bottom of the electrical cabinet 2 is fixedly connected to the base platform 1 through the vibration damping base 3. Side vibration damping components 4 are installed on the sides and back of the electrical cabinet 2. The side vibration damping components 4 are fixedly connected to the press body 8 through the connecting beam 7, ensuring that the overall frequency of the electrical cabinet 2 is much lower than the vibration frequency of the press, greatly reducing the amplitude and minimizing vibration damage to electronic components.

[0022] The system adopts a composite layout of multi-stage bottom vibration damping and side vibration damping. The bottom vibration damping base 3 completely isolates the electrical cabinet 2 from the foundation platform 1, preventing the upward transmission of ground vibration. The first wire rope vibration damper 33 is responsible for buffering and vibration isolation under normal working conditions. Together with the secondary vibration damping unit 36, it forms a composite vibration damping system with segmented stiffness variation, which takes into account both gentle vibration isolation for small vibrations and strong protection against large impacts. Side vibration damping components 4 are arranged bidirectionally on the sides and back to absorb the lateral sway and torsional vibration of the cabinet. The overall vibration damping coverage is comprehensive, which greatly improves the stability and safety of the electrical cabinet under the strong vibration conditions of the press.

[0023] In this embodiment, the press body 8 is located on the back side of the electrical cabinet 2. Adjacent electrical cabinets 2 are fixedly connected by a protective plate 5 to improve the overall appearance. The protective plate 5 is bolted to the electrical cabinet 2. A hollow rubber strip 6 is fixed on the outer wall of the electrical cabinet 2. The hollow rubber strip 6 is V-shaped and is located at the joint between the electrical cabinet 2 and the protective plate 5 to avoid collision and wear between the cabinet body and the protective plate 5 and noise when the electrical cabinet 2 vibrates.

[0024] The protective plate 5 forms an overall protection for multiple electrical cabinets 2. The hollow rubber strip 6 flexibly isolates the electrical cabinet 2 from the protective plate 5, avoiding vibration and noise caused by rigid contact and collision. At the same time, it absorbs the vibration transmitted between electrical cabinets 2, ensuring that the operation of a single electrical cabinet 2 does not interfere with each other, and improving the overall operational stability of the electrical cabinet group 2.

[0025] like Figure 3 As shown, the vibration damping base 3 includes a base plate 31, a top plate 32, a first wire rope vibration damper 33, guide posts 34, guide holes 35, and a secondary vibration damping unit 36. The base plate 31 is fixedly mounted on the foundation platform 1 by bolts or welding. The top plate 32 is fixedly mounted on the bottom of the electrical cabinet 2. Several first wire rope vibration dampers 33 are provided and fixedly mounted between the base plate 31 and the top plate 32. Several guide posts 34 are provided and vertically fixedly mounted on the base plate 31. Guide holes 35 are provided at corresponding positions on the top plate 32. The guide posts 34 and guide holes 35 are slidably connected to each other to provide guidance. The secondary vibration damping unit 36 ​​is fixedly mounted on the base plate 31 to provide secondary vibration damping.

[0026] The secondary vibration damping unit 36 ​​can be a polyurethane damping block or a disc spring assembly. The polyurethane damping block has high damping and gentle buffering, while the disc spring assembly has strong load-bearing capacity and stable stiffness. Both can provide nonlinear stiffness support according to the impact intensity, quickly absorbing the remaining impact energy under large impact conditions, avoiding the impact force from being directly transmitted to the internal components of the electrical cabinet 2, protecting the electrical components from damage by strong vibration, and at the same time, the structure is durable and the maintenance cost is low. The height of the secondary vibration damping unit 36 ​​is lower than that of the first wire rope vibration damper 33. The height difference arrangement realizes the graded triggering working mechanism, so that under low frequency and small amplitude, only the first wire rope vibration damper 33 works, ensuring that the vibration isolation is gentle and not harsh. When encountering a high frequency and large impact (exceeding the effective damping stroke of the wire rope), the top plate 32 will contact and squeeze the secondary vibration damping unit 36, realizing a nonlinear jump in stiffness. This avoids the redundant participation of the secondary vibration damping unit 36 ​​under normal conditions from affecting the vibration isolation effect, and can provide strong support at the moment of strong impact, effectively preventing hard bottom impact from damaging the cabinet.

[0027] In this embodiment, there are several first wire rope vibration dampers 33, and several columns of first wire rope vibration dampers 33 are arranged. All columns of first wire rope vibration dampers 33 are arranged in a crisscross pattern on the surface of the base plate 31. The multiple columns of crisscross arrangement make the bottom vibration damping force uniform, fully cover the cabinet support area, avoid local stress concentration, and the horizontal and vertical crisscross arrangement can simultaneously isolate horizontal swaying vibrations in multiple directions, greatly improve the overall vibration isolation effect at the bottom, and ensure the stability of the electrical cabinet in complex vibration environment.

[0028] like Figure 4 and Figure 5As shown, the side vibration damping assembly 4 includes a second wire rope vibration damper 41, a ball joint connector 43, a slider 44, and a slide rail 45. One end of the second wire rope vibration damper 41 is fixedly connected to the press body 8 through a connecting beam 7, and the other end of the second wire rope vibration damper 41 is fixedly connected to the ball joint connector 43. The slide rail 45 is vertically fixed on the outer wall of the electrical cabinet 2, and the slider 44 is slidably disposed in the slide rail 45. The slider 44 is also fixedly connected to the ball joint connector 43, so that the side of the electrical cabinet 2 no longer uses a direct rigid bolt connection to the vibration damper. When the electrical cabinet 2 undergoes vertical displacement or slight rotation around the axis, the ball joint connector 43 on the side can slide accordingly or rotate slightly on its own, absorbing only the radial impact force and releasing the axial and torsional shear stress, effectively avoiding damage to the side wall of the electrical cabinet 2 and ensuring the vibration damping effect.

[0029] The flexible lateral vibration damping structure, which uses a slide rail 45 and a slider 44 in conjunction with a ball joint, allows the slider 44 to slide freely vertically along the slide rail 45 when the electrical cabinet 2 undergoes horizontal displacement or torsion, without generating additional shearing or pulling forces, thus preventing tearing and damage at the connection between the vibration damper and the cabinet from the source. The second wire rope vibration damper 41 can freely extend and retract to absorb the amplitude, and the ball joint connector 43 allows for small-angle deflection of the connection point, adapting to the following displacement and slight torsion conditions of the electrical cabinet 2, greatly improving the reliability and service life of lateral vibration damping.

[0030] In this embodiment, the second wire rope vibration damper 41 is arranged laterally. Both ends of the second wire rope vibration damper 41 are connected to the connecting plate 42 by bolts. The connecting plate 42 has an L-shaped structure and several reinforcing ribs are fixed inside the connecting plate 42. The L-shaped connecting plate 42 is firmly installed and has a large bearing area, so as to expand the area of ​​the end of the second wire rope vibration damper 41 through the connecting plate 42, thereby improving the connection between the second wire rope vibration damper 41 and the connecting beam 7 and the ball joint connector 43. The internal reinforcing ribs significantly improve the structural rigidity of the connecting plate, prevent deformation and cracking due to long-term vibration and impact, and ensure that the second wire rope vibration damper 41 is connected firmly and reliably.

[0031] The ball joint connector 43 is located close to the center of the slider 44 to shorten the lever arm, reduce the lateral torque on the slide rail 45, and improve the overall stability. A butyl rubber bushing is provided at the connection between the ball joint connector 43 and the slider 44. The second wire rope vibration damper 41 is responsible for handling large amplitude and low frequency vibrations. The rubber bushing can further absorb high frequency micro-amplitude vibrations, buffer the impact stress at the connection point, compensate for assembly coaxial errors, reduce rigid friction and wear, reduce operating noise, make the ball joint rotation smoother and gentler, and extend the overall service life of the lateral vibration damping assembly.

[0032] Example 2 In another typical embodiment of the present invention, a vibration reduction method is proposed, comprising: Place the base platform 1 horizontally and fix it in the installation area to ensure that the base platform 1 is stable and bears the weight evenly. Move the electrical cabinet 2 to the corresponding position on the base platform 1. Install the vibration damping base 3 at the bottom of the electrical cabinet 2 and install the side vibration damping components 4 on the side and back of the electrical cabinet 2. The side vibration damping components 4 are fixedly connected to the press body 8 through the connecting beam 7.

[0033] Specifically, the base plate 31 is fixed to the foundation platform 1 by bolts or welding, the top plate 32 is fixed to the bottom of the electrical cabinet 2, a number of first wire rope vibration dampers 33 are installed between the base plate 31 and the top plate 32, the guide post 34 is vertically fixed on the base plate 31, the top plate 32 has a corresponding guide hole 35, the guide post 34 slides into the guide hole 35 to achieve a guiding connection, and the secondary vibration damping unit 36 ​​is fixed on the base plate 31 so that the height of the secondary vibration damping unit 36 ​​is lower than that of the first wire rope vibration damper 33; The slide rail 45 is vertically fixed to the outer wall of the electrical cabinet 2, ensuring that the slide rail 45 is vertical and parallel to the side wall of the electrical cabinet 2. The slider 44 is installed inside the slide rail 45 to ensure smooth sliding, so that the ball joint connector 43 is close to the center of the slider 44 to shorten the lever arm and reduce the lateral torque on the slide rail 45. One end of the second wire rope vibration damper 41 is fixed to the ball joint connector 43 through the connecting plate 42, and the other end of the second wire rope vibration damper 41 is fixed to the press body 8 through the connecting beam 7.

[0034] After the vibration damping base 3 and the side vibration damping assembly 4 are installed, a protective plate 5 is installed between adjacent electrical cabinets 2. The protective plate 5 is fixed to the electrical cabinet 2 with bolts. The protective plate 5 is located on the side of the electrical cabinet 2 away from the press body 8 to ensure a flat overall appearance. A V-shaped hollow rubber strip 6 is installed at the joint between the electrical cabinet 2 and the protective plate 5 to prevent collisions, wear and noise generation during vibration.

[0035] The electrical cabinet 2 is isolated from the foundation platform 1 by the vibration damping base 3. The first wire rope vibration damper 33 works at low frequency and small amplitude to achieve foundation vibration isolation. The side vibration damping component 4 absorbs the vibration of the side wall of the electrical cabinet 2 by sliding through the ball joint connector 43.

[0036] Specifically, when the press body 8 generates a high-frequency large impact that exceeds the stiffness of the first wire rope vibration damper 33, the top plate 32 contacts the secondary vibration damping unit 36, achieving a non-linear increase in stiffness, avoiding the electrical cabinet from hitting the bottom hard, and preventing damage to electronic components.

[0037] Under normal operating conditions, the first wire rope vibration damper 33 is used to achieve efficient and gentle vibration isolation, ensuring the stable operation of the electrical cabinet. When there is a high frequency and a large impact, the secondary vibration damping unit 36 ​​is automatically triggered to achieve a step-by-step increase in stiffness, quickly absorb strong impact energy, prevent hard collisions to the bottom, effectively protect the structure of the electrical cabinet 2 and the internal precision components, and greatly improve the equipment's impact resistance and reliability.

[0038] When the press body 8 generates low-frequency, large-amplitude vibrations or slight torsion around its axis, the side wall of the electrical cabinet 2 will undergo follow-up displacement. The extension and retraction of the second wire rope vibration damper 41 absorbs the amplitude, the slider 44 slides within the slide rail 45, and the ball joint connector 43 allows the connection point to rotate at a small angle. This ensures that the second wire rope vibration damper 41 only absorbs radial vibrations, while axial and torsional stresses are released. The side wall of the electrical cabinet will not be damaged due to rigid constraints, thus extending its service life. The lateral flexible vibration damping system can adapt to the large-amplitude oscillations and slight torsional movements of the electrical cabinet 2. By releasing displacement stress through extension, sliding, and rotation, it avoids the lateral vibration damper from being subjected to excessive shear force, which could lead to failure or damage to the cabinet. This achieves all-round flexible buffering and absorption of lateral and torsional vibrations, further improving the safety and stability of the electrical cabinet under complex and harsh vibration conditions.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
