Rolling mill of composite material rolling system

Abstract

The invention discloses a rolling mill of a composite material rolling system, which belongs to the technical field of composite material rolling, and comprises a roller and a vibration assembly, and the vibration effect is transmitted between the vibration assembly and the roller through a damping coupling path. The damping coupling path is a non-rigid transmission path, when the vibration effect of the vibration assembly excites the roller through the damping coupling path, a forced vibration system is formed, and when the roller is subjected to steady-state and periodic excitation of the vibration assembly, the roller finally forms periodic vibration with steady-state vibration frequency and amplitude. For a linear system provided by the vibration assembly, when the roller is subjected to steady-state and periodic excitation, the steady-state response achieved after the roller is subjected to a transient process has the same frequency as the vibration effect, and the corresponding amplitude is reduced. Therefore, vibration is transmitted through a non-rigid path, and the process requirements of high frequency and small amplitude are met more easily.

Description

Technical Field

[0001] The invention belongs to the technical field of composite material rolling, and specifically relates to a rolling mill for a composite material rolling system. Background Art

[0002] Metal laminated composites are in urgent demand in fields such as aerospace, rail transit, and national defense and military industries by superimposing different component metals and integrating the superior properties of each component. The rolling composite process uses the powerful pressure of a rolling mill to cause plastic deformation of two or more different metal sheets in the solid state, thereby achieving atomic-level close bonding. However, in the traditional rolling composite process, there are problems with poor interfacial bonding quality due to low dislocation rate, insufficient metal fluidity, and insufficient fragmentation of the oxide film / hardened layer at the interface to be compounded.

[0003] During the rolling process of composite materials, providing a horizontally vibrating artificial and controllable specific frequency and amplitude to the rolling roll is an advanced process improvement technology. On the one hand, the stress alternation generated by vibration promotes the proliferation and movement of dislocations, reduces the resistance of dislocation movement, and thus promotes the mutual embedding and biting of micro-protrusions on the interface; on the other hand, vibration can more effectively break and remove the residual oxide film and contamination layer on the interface, exposing more fresh and highly active metal atoms.

[0004] In some rolling processes, ultrasonic waves are used to provide a vibration power source for the rolling roll, but the problems of energy dissipation and attenuation of ultrasonic waves greatly restrict the development of this technology in the field of vibration rolling. In some rolling processes, pistons or eccentric mass blocks are used to force the rolling roll to generate a synchronous reciprocating motion in the horizontal direction, but the vibration method generated by pushing the rolling roll through such a rigid mass block has the characteristics of large amplitude and low vibration frequency, and it is difficult to meet the process requirements. In addition, when the lateral vibration blocking force of the rolling roll is too large, the forced vibration form of rigid connection is prone to cause the risk of overload of the vibration components.

[0005] The patent with the publication number CN108144966A discloses an electromagnetic vibration rolling roll for rolling metal composite plates. A plurality of electromagnetic vibration devices are installed on the mandrel of the rolling roll body, and the vibration mechanical energy generated by electromagnetic vibration is used to cause the rolling roll body to vibrate during the rolling process, thereby breaking the oxide film on the contact surface of the bimetallic material. However, the temperature of the environment where the rolling mill is located is usually high, and in addition, the electromagnetic vibration device itself generates a lot of heat during operation. High temperature is likely to affect the performance of the permanent magnet in the electromagnetic vibration device, and it is difficult to arrange a cooling system in the rolling roll, so the service life and operation stability of the vibration device are insufficient. Summary of the Invention

[0006] The purpose of the present invention is to provide a rolling mill for a composite material rolling system to solve the problems mentioned in the above-mentioned prior art.

[0007] Provide a rolling mill for a composite material rolling system, including: Roller; Vibration assembly, and a vibration action is transmitted between the vibration assembly and the roller through a damping coupling path.

[0008] As a further embodiment of the present invention: the damping coupling path includes a non-contact electromagnetic excitation action between the vibration assembly and the roller.

[0009] Non-contact electromagnetic excitation transmits vibration energy through an electromagnetic field, avoiding direct mechanical contact. On the one hand, the non-contact design of electromagnetic excitation enables the electromagnetic assembly to be away from the high-temperature area of the roller, avoiding demagnetization of the permanent magnet; on the other hand, the high-frequency vibration effect of electromagnetic excitation is used to increase the vibration frequency of the roller.

[0010] As a further embodiment of the present invention: the damping coupling path includes a coupling channel penetrating through the roller and a damping medium filled between the vibration assembly and the coupling channel.

[0011] The vibration assembly drives the damping medium to flow reciprocally in the coupling channel, and the vibration action is transmitted to the roller through the interfacial shear force and viscous force of the damping medium, forcing the two subsystems of the roller and the vibration assembly to be coupled with each other to transmit vibration. Using a fluid medium to establish a damping coupling path between the vibration assembly and the roller, while transmitting the vibration action, flexible contact is achieved to prevent overloading and damaging the vibration source.

[0012] As a further embodiment of the present invention: the vibration assembly includes a vibration source for driving the damping medium to move reciprocally in the coupling channel.

[0013] In this solution, the driving effect of the vibration assembly is directly applied to the damping medium to force the damping medium to flow reciprocally, and the vibration assembly and the roller rely on the shear force and viscous force formed between the flow of the damping medium and the coupling channel for transmission.

[0014] As a further embodiment of the present invention: the vibration assembly includes a vibration source and a reciprocating rod, the vibration source is used to drive the reciprocating rod to move reciprocally in the coupling channel, and the damping medium is filled between the reciprocating rod and the coupling channel.

[0015] In this solution, the driving effect of the vibration assembly is applied to the reciprocating rod, and the reciprocating movement of the reciprocating rod is transmitted to the inner wall of the coupling channel through the damping medium, thereby forcing the roller to vibrate. There is only a micro-gap between the reciprocating rod and the coupling channel wall, and the vibration action is indirectly transmitted from the reciprocating rod to the damping medium, significantly reducing the transmission path of the interlayer shear force of the damping medium and improving the energy transmission efficiency.

[0016] As a further embodiment of the present invention: the damping medium includes damping blocks and a liquid damper, and the liquid damper is filled between the two damping blocks.

[0017] The damping block is solid, and the interlayer shear force transfer effect of the solid damping block is strong, and it can seal the liquid damping. The liquid damping is liquid, and the viscosity of the liquid damping is strong, and it can lubricate the damping block. Through the cooperation of the damping block and the liquid damping, the vibration coupling effect between the reciprocating rod and the coupling channel can be significantly improved. The damping block and the liquid damping can promote form self-sustainment, performance complementarity and effect enhancement.

[0018] As a further embodiment of the present invention: spiral rifling is formed on the inner wall of the coupling channel.

[0019] The spiral rifling forces the flow of the liquid damping medium in the coupling channel to change from linear reciprocation to partial spiral propulsion, increasing the flow resistance of the damping medium and thus improving the energy transfer efficiency. The spiral rifling can enhance the laminar flow effect of the liquid damping medium, enhance the steady state and periodicity of the excitation, maintain the linear transmission of the system, and thus improve the frequency synchronization of the roll response.

[0020] As a further embodiment of the present invention: a plurality of the coupling channels are arranged circumferentially along the roll.

[0021] The vibration actions in the plurality of coupling channels are carried out synchronously, and a resonance effect can be formed. By connecting in parallel through multiple channels, the contact area between the damping medium and the roll is increased, and the energy transfer rate is improved.

[0022] As a further embodiment of the present invention: the roll includes an outer roll and an inner roll arranged in sequence from outside to inside, and the coupling channel is formed inside the inner roll.

[0023] The coupling channel is built inside the inner roll. The inner roll is dedicated to vibration transmission, while the outer roll is responsible for rolling force. This avoids the coupling channel from affecting the rolling strength of the roll surface. Compared with the outer roll dedicated to rolling force, the inner roll can be made of a material that cooperates more closely with the damping medium.

[0024] As a further embodiment of the present invention: an elastic damping member is provided at the end of the roll.

[0025] The elastic damping member is installed at the end of the roll, which can effectively reduce the height of the resonance peak, weaken the inertial effect of the roll vibration, provide mechanical buffering and define the physical path and characteristics of the coupling under this system.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The damping coupling path is a non-rigid transmission path. When the vibration action of the vibration component excites the roll through the damping coupling path, a forced vibration system is formed. When the roll is subjected to the steady-state and periodic excitation of the vibration component, the roll will finally form a periodic vibration with a steady-state vibration frequency and amplitude. Vibration promotes the embedding of micro-protrusions at the metal interface and the fragmentation of the oxide film, improving the bonding quality of the composite material.

[0027] 2. The damping coupling path has an energy buffering characteristic, can absorb vibration shocks, and prevent the vibration components from directly bearing the inertial resistance of the roll, thereby preventing the vibration components from being overloaded due to excessive roll blocking force, and significantly improving the service life and stability of the vibration system.

[0028] 3. For the linear system provided by the vibration components, when the roll is subjected to steady-state and periodic excitation, the steady-state response reached by the roll after experiencing the transient process will have the same frequency as the vibration effect and reduce the corresponding amplitude. Therefore, by transmitting vibration through the non-rigid path, it is easier to meet the process requirements of high frequency and small amplitude. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will describe and explain the present invention in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] Obviously, the accompanying drawings in the following description are only some examples or embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, the present invention can also be applied to other similar scenarios based on these drawings. In addition, it can also be understood that although the efforts made in such a development process may be complex and lengthy, for those of ordinary skill in the art related to the content disclosed in the present invention, some design, manufacturing or production changes based on the technical content disclosed in the present invention are only conventional technical means and should not be understood as insufficient disclosure of the content of the present invention.

[0034] However, there will be cases where unnecessary details are omitted. For example, there are cases where the detailed description of well-known matters is omitted and the repeated description of actually identical structures is omitted. This is to avoid the following description becoming unnecessarily lengthy and to facilitate the understanding of those skilled in the art. In addition, the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present invention and are not intended to limit the subject matter recited in the claims.

[0035] Please refer to Figure 1 As shown, the rolling mill of the composite material rolling system in the embodiment of the present invention includes a rolling roll 1 and a vibration assembly 2, and the vibration assembly 2 transmits a vibration effect to the rolling roll 1 through a damping coupling path.

[0036] The rolling mill provided by the present invention is used for the rolling process of metal laminated composites, and specifically further includes a bench 4, a lifting mechanism 5 and a driving mechanism. The rolling roll 1 includes an upper roll 14 and a lower roll 15. The lifting mechanism 5 is located at the top of the bench 4 and cooperates with the upper roll 14 to drive the upper roll 14 to lift. The lifting mechanism 5 has two constraint points in the length direction of the upper roll 14 that restrict the radial movement of the upper roll 14. In addition to the rotational freedom between the upper roll 14 and the constraint points, there can also be a freedom of axial movement. The lower roll 15 cooperates with the bench 4. The bench 4 has two constraint points in the length direction of the lower roll 15 that restrict the radial movement of the lower roll 15. In addition to the rotational freedom between the lower roll 15 and the constraint points, there can also be a freedom of axial movement. It should be noted that the vibration system provided by the present invention can act on the upper roll 14 or the lower roll 15 alone, or can act on the upper roll 14 and the lower roll 15 simultaneously. Whether there is a freedom of axial movement between the rolling roll 1 and the constraint point is determined by whether a vibration effect is applied to this roll.

[0037] Since the rolling mill is used for composite material rolling, the driving mechanism is composed of two sets of actuators 61 and a universal joint 62. The two actuators 61 respectively drive the upper roll 14 or the lower roll 15 to rotate through the corresponding universal joints 62. The upper roll 14 and the lower roll 15 are respectively driven by independent actuators 61 to meet the requirement of speed difference between different rolling rolls 1 due to different ductility of different materials, so as to compensate for the deformation difference between materials.

[0038] To enhance the interfacial bonding effect between different component metals, the rolling mill applies an axial vibration to the roll 1 during the rolling process. The vibration promotes the embedding of micro-protrusions at the metal interface and the fragmentation of the oxide film, improving the bonding quality of the composite material. The vibration is generated by the vibration assembly 2. Different from directly transmitting vibration energy through a rigid connection, in the rolling mill of the present invention, a damping coupling path is established between the vibration assembly 2 and the roll 1, and the vibration energy is transmitted through non-contact or flexible contact.

[0039] Specifically, the damping coupling path refers to a non-rigid physical connection channel established between the vibration assembly 2 and the roll 1. This channel uses the partition space and / or damping as the medium for transmitting vibration energy, realizing the controllable energy transmission and dynamic response adjustment between the vibration assembly 2 and the roll 1. The vibration assembly 2 provides a steady-state and periodic linear excitation to the roll 1. Since the connection between the vibration assembly 2 and the roll 1 is non-rigid, the steady-state response of the roll 1 system after experiencing a delay process will have the same frequency as the excitation source.

[0040] It should be noted that the vibration assembly 2 provides vibration energy through the vibration source 21. The existence of the damping coupling path does not change the frequency of the steady-state response of the roll 1. It mainly affects the amplitude and phase of the response. Due to the energy dissipation process of the damping, the amplitude of the roll 1 in the final steady state is smaller than the amplitude of the excitation source. Therefore, compared with the low-frequency forced vibration with a rigid connection and the low-amplitude ultrasonic vibration with a relatively fast energy dissipation speed, the present invention can provide a vibration source 21 with a higher excitation frequency to increase the response frequency of the roll 1, and provides a scheme basis for increasing the vibration amplitude range of the roll 1 by increasing the power of the vibration source 21. For a vibration device such as a hydraulic vibrator, the vibration frequency is usually only below 50Hz due to the limitation of the commutation frequency of the directional control valve.

[0041] Furthermore, it should be noted that the existence of the damping causes the vibration of the roll 1 to lag behind the vibration of the vibration source 21. That is to say, although they have the same steady-state frequency, they are not in the same phase. There is a certain delay time for the roll 1 to enter the steady-state vibration state and enter the steady-state stop state.

[0042] Specifically, please refer to Figure 1 As shown, the damping coupling path includes a non-contact electromagnetic excitation between the vibration assembly 2 and the roll 1, that is, the vibration assembly 2 interacts with the permanent magnet through the alternating magnetic field generated by the current, generating a vibration frequency significantly higher than 50Hz. The specific process of the electromagnetic excitation is that the electromagnetic coil in the vibration assembly 2 is energized with high-frequency alternating current to generate an alternating magnetic field, and the permanent magnet has an induced eddy current. The eddy current magnetic field interacts with the original magnetic field to generate the vibration source 21.

[0043] In a specific embodiment, the permanent magnet is located at one end of the roll 1, and there is an extension section between the permanent magnet and the end of the roll 1. The vibration energy is transmitted between the permanent magnet and the roll 1 through a rigid connection. The electromagnetic coil and the permanent magnet are not within the same structural system. Since the electromagnetic coil and the permanent magnet can be physically isolated from the high-temperature roll 1, the situation of high-temperature demagnetization is effectively avoided. And due to the spatial isolation between the electromagnetic coil and the permanent magnet, the vibration assembly 2 is prevented from generating an overload problem due to excessive blocking force of the roll 1.

[0044] Specifically, please refer to Figure 2 As shown, the damping coupling path includes a coupling channel 11 running through the inside of the roll 1, and a damping medium 32 filled between the vibration assembly 2 and the coupling channel 11. The high-frequency vibration provided by the vibration source 21 is indirectly transmitted to the roll 1 through the damping medium 32 in the coupling channel 11, enabling the roll 1 to have a dynamic response process. Specifically, the damping medium 32 is forced to move in the coupling channel 11, converting the mechanical energy of the vibration source 21 into the kinetic energy of the damping medium 32. The interlayer shear force generated when the damping medium 32 moves pushes the wall of the coupling channel 11, and then pushes the roll 1 to move.

[0045] In a specific embodiment, the vibration source 21 is composed of a permanent magnet and an electromagnetic coil. The permanent magnet and the electromagnetic coil are both located within the vibration assembly 2 to form a structural system. The permanent magnet serves as the vibration output end and undergoes piston motion under the alternating magnetic field of the electromagnetic coil. The damping medium 32 is liquid. The front piston of the vibration source 21 changes the flow direction of the damping medium 32 through work, and the damping medium 32 then reciprocates within the coupling channel 11, thereby forcing the roll 1 to respond to the vibration.

[0046] Under this scheme, a physical isolation is formed between the vibration source 21 and the roll 1 through the damping medium 32. The driving effect of the vibration assembly 2 is directly applied to the damping medium 32 to force the damping medium 32 to flow back and forth. The vibration assembly 2 and the roll 1 rely on the shear force and viscous force formed between the flow of the damping medium 32 and the coupling channel 11 for transmission.

[0047] It should be noted that under the flexible connection system of the constructed damping medium 32 and the coupling channel 11, the vibration source 21 can also use a hydraulic vibrator, a reciprocating compressor, a pump, etc. as the driving source, which can play a role in avoiding load.

[0048] Further, please refer to Figure 3As shown in the figure, in addition to the vibration source 21, the vibration assembly 2 further includes a reciprocating rod 22. The vibration source 21 is used to drive the reciprocating rod 22 to reciprocate within the coupling channel 11, and the damping medium 32 is filled between the reciprocating rod 22 and the coupling channel 11. The reciprocating rod 22 extends into the interior of the coupling channel 11, and a flexible connection is established between the reciprocating rod 22 and the coupling channel 11 through the damping medium 32. By the extension of the reciprocating rod 22, the force transmission area between the vibration source 21 and the roller 1 can be increased, that is, the shear force and viscous force transmission area of the damping medium 32 can be increased, and the energy transmission efficiency can be improved.

[0049] In a specific embodiment, the vibration source 21 is composed of a permanent magnet and an electromagnetic coil. Both the permanent magnet and the electromagnetic coil are located within the vibration assembly 2 to form a structural system. The permanent magnet is disposed as the vibration output end at the end of the reciprocating rod 22, and the front end of the reciprocating rod 22 extends into the coupling channel 11. The permanent magnet forces the reciprocating rod 22 to perform a piston motion under the alternating magnetic field of the electromagnetic coil. The working end of the reciprocating rod 22 transmits the vibration to the damping medium 32, realizing the flexible connection and kinetic energy transmission between the vibration assembly 2 and the roller 1.

[0050] Furthermore, the reciprocating rod 22 can be used as an extension rod to extend the distance between the vibration assembly 2 and the roller 1, avoiding the demagnetization of the permanent magnet caused by the hot area of the roller 1.

[0051] In a specific embodiment, the damping medium 32 is a compression spring.

[0052] Generally speaking, since a damping effect is established between the roller 1 and the vibration assembly 2 through the damping medium 32, the damping medium 32 can effectively reduce the height of the vibration peak of the roller 1, weaken the inertial effect of the vibration of the roller 1, and avoid the difficulty of the vibration return stroke of the roller 1 due to the lack of reaction force limitation. The roller 1 and the vibration assembly 2 constitute two coupled dynamic subsystems, and the damping medium 32 serves as the coupling path between the two dynamic subsystems, participating in the shaping of the dynamic interaction between the two subsystems, providing a phase shift path for the roller 1 and at the same time providing a reaction force for the return stroke.

[0053] Further, please refer to Figure 3 and Figure 4 As shown in the figure, the damping medium 32 includes damping blocks 321 and a liquid damper 322. The liquid damper 322 is filled between the two damping blocks 321.

[0054] In one embodiment, the inner ring of the damping block 321 is fixed to the reciprocating rod 22. When the reciprocating rod 22 reciprocates, the outer ring of the damping block 321 is in sliding contact with the coupling channel 11. This solution mainly transmits the vibration through the shear force and viscous force between the liquid damper 322 and the coupling channel 11 and constructs the vibration return stroke damping. The damping block 321 acts as a seal to constrain the shape of the liquid damper 322, and on the other hand, the liquid damper 322 provides a lubricating effect to the damping block 321.

[0055] In one embodiment, the inner ring of the damping block 321 is fixed to the reciprocating rod 22, while the outer ring of the damping block 321 is fixed to the coupling channel 11. This solution mainly transmits vibration through the interlayer shear force of the damping block 321 itself and constructs vibration return damping.

[0056] The inner wall of the coupling channel 11 is formed with spiral rifling, which is used to guide the liquid damping medium 32 to achieve precession flow, thereby increasing the blocking force between the damping medium 32 and the coupling channel 11 and improving the energy transfer efficiency.

[0057] Multiple coupling channels 11 are arranged along the circumference of the roll 1. Single-channel excitation leads to excessive local stress in the roll 1, while multi-channel distribution realizes uniform pressure distribution around the roll 1, thereby suppressing amplitude fluctuation of the roll 1.

[0058] See also Figure 2 and Figure 3 As shown, the roller 1 includes an outer roller 12 and an inner roller 13, which are arranged in sequence from the outside to the inside. The coupling channel 11 is formed inside the inner roller 13. The inner roller 13 and the outer roller 12 are made of different materials. The outer roller 12 is used to press the plate, while the inner roller 13 is used for vibration transmission.

[0059] See also Figure 1 As shown, an elastic damping member 31 is provided at the end of the roller 1. When vibration is transmitted between the vibration assembly 2 and the roller 1 via non-contact electromagnetic excitation, the elastic damping member 31 at the end of the roller 1 provides a cushioning effect. However, when the coupling channel 11 passes through the interior of the roller 1 and the space between the vibration assembly 2 and the coupling channel 11 is filled with a damping medium 32, although the damping medium 32 provides a cushioning effect during vibration, if the damping medium 32 is liquid damping 322, the damping medium 32 does not have the potential energy storage capacity of a spring. Under the action of vibration, the roller 1 may produce a large displacement relative to the constraint point. Therefore, the elastic damping member 31 provides a displacement constraint, limiting the position offset of the roller 1 to a certain range.

[0060] In a specific embodiment, the elastic damping member 31 is a spring or an elastic block.

[0061] It should be noted that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments are merely examples, and any embodiments having substantially the same structure and effect as the technical concept within the scope of the technical solution of the present invention are all included in the technical scope of the present invention. In addition, without departing from the scope of the present invention, other embodiments that can be conceived by those skilled in the art and that combine some of the constituent elements in the embodiments are also included in the scope of the present invention.
