Description

Technical Field

[0001] The present invention belongs to the technical field of metal sheet rolling equipment, and particularly relates to a composite metal plate rolling mill. Background Art

[0002] A composite metal plate is a composite material formed by metallurgically bonding metal plates with different properties at the interface using various composite technologies. Through appropriate material selection and reasonable structural design, the composite metal plate can greatly improve many properties of a single metal material, such as thermal expansion, strength, toughness, wear resistance, corrosion resistance, electrical properties, magnetic properties, etc., and is thus widely applied to industrial fields such as petroleum, chemical industry, shipbuilding, metallurgy, electric power, water conservancy, transportation, environmental protection, food, and pharmaceuticals. In addition to the structural and functional characteristics, the metal composite plate can also save the use of precious metals and significantly reduce the cost of various equipment materials. Existing composite metal plates generally use methods such as explosive welding and composite rolling for composite processing. Among them, due to the safety hazards of the explosive welding composite processing method, a large amount of dust is generated during the explosion, polluting the environment, and continuous production and processing cannot be carried out. Therefore, the more commonly used composite processing method at present is composite rolling. However, it has been found that during the composite rolling process, due to the poor quality of the bonding surface between the metal plates and the insufficient bonding degree through extrusion, the produced metal composite plate is prone to delamination, so the production quality cannot be guaranteed. In this regard, in the Chinese patent with the patent number CN201810137565.2 and the patent name of an electromagnetic vibration roll for rolling a metal composite plate, a plurality of electromagnetic vibration devices are installed on the mandrel of the roll body. By using the vibration mechanical energy generated by electromagnetic vibration, the roll body generates vibration during the rolling process, thereby breaking the oxide film on the contact surface of the bimetallic material, and further exposing more fresh metal on the bimetallic contact surface, increasing the bonding area and improving the bonding strength of the bimetallic plate. Among them, the frequency of electromagnetic vibration can be adjusted according to the bonding strength of the slab, and the frequency of each electromagnetic vibrator can also be adjusted separately according to the edge cracking situation of the plate until the requirements are met. The electromagnetic vibration roll disclosed in this patent can improve the bonding strength of the composite metal plate when applied. However, it has been found in the actual application process that a large amount of heat will be generated due to friction during the rolling process of the roll on the composite metal plate. Especially when the external environmental temperature is relatively high, the heat generated during the rolling process of the roll cannot be ignored. At this time, when the roll continues to be in a high-temperature state, the internal electromagnetic vibrator is prone to electronic component aging or fusing due to high temperature, resulting in its control failure, and thus it cannot normally exert its vibration effect, seriously affecting the service life of the roll.

[0022] 1. The present invention sets a high-frequency vibrator inside the first rolling roller group, which can generate a forging impact force on the composite metal plates entering between the rolling roller assemblies, thereby refining the grains on the metal surface and causing microscopic bonding between the composite metal plates. At the same time, during the working process, the vibration generated by the high-frequency vibrator can drive the vibration guide rod in the cooling system to vibrate at high frequency. At this time, the high-pressure air intake pipe inputs high-pressure air from the outside, so that the cooling lubricant entering the cooling lubricant chamber from the cooling lubricant channel in the vibration guide rod forms liquid microparticles. The formed liquid microparticles are then sprayed from the cooling hose on the cooling lubricant outlet to the rolling roller assemblies to cool the rolling roller assemblies. The cooling of the rolling roller assemblies after the cooling lubricant is made into liquid microparticles can effectively improve the cooling effect of the cooling lubricant, making the cooling more uniform. At the same time, spraying the cooling lubricant made into liquid microparticles between the rolling roller assemblies can also reduce the friction between the rolling rollers and the metal plates, thereby reducing the damage to the rolling rollers caused by friction.

[0023] 2. The high-frequency vibrator provided by the present invention is a mechanical vibration, which can effectively avoid the phenomenon that the internal electronic components of the vibrator age or fuse due to overheating when the roll assembly is continuously in a high-temperature state compared with the electromagnetic vibrator in the prior art. Therefore, the roll assembly can also have a long service life in a high-temperature environment.

[0024] 3. The vibration guide plate provided on the vibration guide rod of the present invention can further strengthen the liquid microatomization of the cooling lubricant, that is, it can make the particle size of the liquid micro-particles formed by the cooling lubricant smaller, thereby further enhancing its cooling effect.

Therefore, the embodiments of the present invention aim to disclose a composite metal plate rolling mill to solve the technical problem that the roll of the composite metal plate rolling mill in the prior art is prone to short service life due to excessive temperature during rolling.

[0036] The following further specifically introduces the composite metal plate rolling mill disclosed in the present invention in conjunction with the embodiments shown in the accompanying drawings.

[0037] Embodiment 1

[0038] A composite metal plate rolling mill, as Figure 1 and Figure 2 shown, includes a mounting bracket 1, a roll assembly, a driving mechanism 2, and a cooling system;

[0039] The roller assembly includes a first roller group 3 and a second roller group 4. The first roller group 3 includes a first roller 3-1, two first roller sleeves 3-2 rotatably connected to the opposite ends of the first roller 3-1, and a transverse connecting plate 3-3 fixed to the two first roller sleeves 3-2. The first roller group 3 is slidably connected to the mounting bracket 1 through the first roller sleeve 3-2. The first roller sleeve 3-2 and the mounting bracket 1 are slidably connected together by using the sliding rails and slots conventionally used in the prior art. It is worth mentioning that the transverse connecting plate 3-3 provided in the first roller group 3 in this embodiment is for the convenience of assembly and connection with the following other structures. In actual application, technicians in this field can choose whether to provide the transverse connecting plate according to actual needs or can use other structures disclosed in the prior art for equivalent replacement according to actual needs. A high-frequency vibrator 5 is provided inside the first roller group 3. Figure 4 As shown, in this embodiment, the high frequency vibrator 5 adopts a mechanical vibration principle, and its specific structure is:

[0040] The high-frequency vibrator 5 includes a main roller shaft 5-1, two high-frequency eccentric shafts 5-2, a power mechanism and a transmission assembly. The main roller shaft 5-1 is rotatably connected to the first roller 3-1. Two relatively arranged mounting turntables 5-3 are fixedly arranged on the main roller shaft 5-1. The two high-frequency eccentric shafts 5-2 are rotatably connected between the two mounting turntables 5-3. The two high-frequency eccentric shafts 5-2 are symmetrically distributed on opposite sides of the main roller shaft 5-1. The two high-frequency eccentric shafts 5-2 are connected to the main roller shaft 5-1 through a transmission wheel. Two eccentric blocks 5-4 are fixedly arranged on the high-frequency eccentric shaft 5-2. It is worth noting that in actual application, the number of the high-frequency eccentric shafts 5-2 is not limited to the above two. Those skilled in the art can determine the specific number according to actual needs. At the same time, in order to ensure stability during use, it is necessary to evenly distribute a number of the high-frequency eccentric shafts 5-2 along the circumferential direction of the mounting turntable 5-3 during setting. The power mechanism is fixed in the first roller group 3, and an output shaft 5-5 is provided on the power mechanism, and the output shaft 5-5 is connected to one end of the main roller shaft 5-1 through a transmission assembly. When in use, the power mechanism drives the main roller shaft 5-1 to rotate through the output shaft 5-5, and under the action of the transmission wheel, the two high-frequency eccentric shafts 5-2 also rotate with the main roller shaft 5-1. At this time, under the action of the eccentric block 5-4, the entire first roller group vibrates, and the composite metal plate passing through the roller assembly forms a certain forging impact force, so that the metal surface grains are refined, and then microscopic bonding occurs between the composite metal plates, thereby improving the bonding strength between the composite metal plates.

[0041] In order to ensure the stability and safety of the high-frequency vibrator 5 during use, the high-frequency vibrator 5 also includes a connecting disk 5-6 and a support seat 5-7. The connecting disk 5-6 is a cylindrical structure with a hollow interior and openings at both ends. The connecting disk 5-6 is fixed between the two mounting turntables 5-3, and the connecting disk 5-6 is covered on the outside of several high-frequency eccentric shafts 5-2. The support seat 5-7 is a disc-shaped structure, and the support seat 5-7 is fixed in the connecting disk 5-6. The outer wall of the support seat 5-7 is fixedly connected to the inner wall of the connecting disk 5-6. A main shaft hole matching the main roller shaft 5-1 is provided at the axial position of the support seat 5-7, and the main roller shaft 5-1 rotates through the main shaft hole. Two secondary shaft holes are also provided on the support seat 5-7. The two secondary shaft holes are arranged one-to-one with the two high-frequency eccentric shafts 5-2, and the high-frequency eccentric shaft 5-2 rotates through the corresponding secondary shaft holes.

[0042] The transmission assembly includes a hollow outer cover 5-8, a partitioning disc 5-9, a left sealing sheet 5-10 and a right sealing sheet 5-11, all of which are arranged in the outer cover 5-8. The outer cover 5-8 is composed of two end covers connected to each other. An annular cavity arranged along its circumferential direction is provided on the inner wall of the outer cover 5-8 at a position corresponding to the axis of the outer cover 5-8, and an electromagnetic coil assembly 5-12 is fixed in the cavity. The main roller shaft 5-1 and the output shaft 5-5 rotate and pass through the opposite ends of the outer cover 5-8 respectively. The partitioning disc 5-9 is fixed to the end of the main roller shaft 5-1, and the left sealing sheet 5-10 is fixed to the partitioning disc 5-9. The left sealing sheet 5-10 and the partitioning turntable 5-9 are arranged to form a left magnetic powder chamber 5-13, the right sealing sheet 5-11 is fixed to the end of the output shaft 5-5, and the right sealing sheet 5-11 and the other side of the partitioning turntable 5-9 are arranged to form a right magnetic powder chamber 5-14, and the right magnetic powder chamber 5-14 and the left magnetic powder chamber 5-13 are filled with magnetic powder particles. When in use, the electromagnetic coil assembly 5-12 is energized to form a magnetic field so that the magnetic powder particles filled in the right magnetic powder chamber 5-14 and the left magnetic powder chamber 5-13 generate magnetism and attract each other, so that the main roller 22 can rotate simultaneously with the output shaft 5-5. The second roller group 4 is fixed on the mounting bracket 1, and the second roller group 4 and the first roller group 3 are arranged parallel to each other; the second roller group 4 adopts the roller assembly conventionally used in the prior art, so its specific structure is not repeated.

[0043] The driving mechanism 2 is fixed on the mounting bracket 1, and the driving mechanism 2 is connected to the first roller group 3 to drive the first roller group 3 to slide up and down; Figure 1As shown, in this embodiment, the driving mechanism 2 adopts a screw transmission assembly, and its specific structure is:

[0044] The driving mechanism includes a transmission sleeve 2-1, two groups of transmission components and a power input device (not shown in the figure). The transmission sleeve 2-1 is fixed on the mounting bracket 1 and corresponds to the position above the first rolling roller group 3. The two groups of transmission components are symmetrically arranged on the transmission sleeve 2-1. The transmission component includes a transmission screw 2-2, a rotary gear 2-3 and a turbine rod 2-4, and the bottom end of the transmission screw 2-2 is movably connected to the transverse connecting plate 3-3 of the first rolling roller group 3 through the mounting sleeve. The top end of the transmission screw 2-2 passes through the transmission sleeve 2-1 and extends to the top of the transmission sleeve 2-1. The rotary gear 2-3 is threadedly screwed on the top end of the transmission screw 2-2. The turbine rod 2-4 is rotatably connected to the top end of the transmission sleeve 2-1 and is meshed and transmission-connected with the rotary gear 2-3. The turbine rods 2-4 on the two groups of transmission components are fixedly connected by a coupling. The power input device is transmission-connected to the turbine rod 2-4 to drive the turbine rod 2-4 to rotate. During the application process, technicians in this field can select a power input device commonly used in the prior art for this embodiment according to actual needs, such as a motor, a rotary motor, etc. At the same time, in the actual application process, the driving mechanism is not limited to the above-mentioned screw transmission assembly, and technicians in this field can also select other driving mechanisms commonly used in the prior art according to actual needs, such as a hydraulic cylinder or a linear cylinder, etc.

[0045] like Figure 3As shown, the cooling system includes a coolant chamber 6 and a vibration guide rod 7. The coolant chamber 6 is arranged inside the transmission sleeve 2-1. In actual application, if the transmission sleeve 2-1 is not provided, the coolant chamber 6 can be directly fixed to the mounting bracket 1. A high-pressure air inlet pipe 8 is provided on one side wall of the coolant chamber 6. When in use and installation, the high-pressure air inlet pipe 8 is connected to an external high-pressure gas source to convey high-pressure gas into the coolant chamber 6. A coolant outlet 9 is provided on another side wall of the coolant chamber 6. A cooling hose (not shown in the figure) is provided on the coolant outlet 9. The vibration guide rod 7 is slidably arranged through the coolant chamber 6. One end of the vibration guide rod 7 is fixedly connected to the top end of the transverse connecting plate 3-3 on the first roll group 3. The other end of the vibration guide rod 7 is provided with a coolant channel 10. A plurality of liquid outlets 11 communicating with the coolant channel 10 are provided on the side wall of the vibration guide rod 7 at a position corresponding to the inside of the coolant chamber 6. During the working process, the vibration generated by the high-frequency vibrator 5 can drive the vibration guide rod 7 in the cooling system to vibrate at a high frequency. At this time, when the high-pressure air inlet pipe 8 inputs high-pressure gas from the outside, the coolant entering the coolant chamber 6 from the coolant channel 10 in the vibration guide rod 7 forms liquid micro-particles. The formed liquid micro-particles are then sprayed onto the roll assembly through the cooling hose on the coolant outlet 9 to cool the roll assembly.

[0046] In order to make the particle size of the liquid micro-particles formed by the coolant smaller and further enhance its cooling effect, a plurality of vibration guide plates 12 are fixedly provided on the side wall of the vibration guide rod 7 at a position inside the coolant chamber 6. The plurality of vibration guide plates 12 are respectively and evenly distributed above and below the liquid outlet 11.

[0047] A return spring 14 is also sleeved on the side wall of the vibration guide rod 7. One end of the return spring 14 is fixedly clamped to the bottom end of the transmission sleeve 2-1. In actual application, if the transmission sleeve 2-1 is not provided, the return spring 14 can be directly fixed to the outer side wall of the coolant chamber 6. The other end of the return spring 14 is fixedly clamped to the top end of the transverse connecting plate 3-3 of the first roll group 3.

[0048] Embodiment 2

[0049] As Figure 5As shown in the figure, the difference between this embodiment and the above-mentioned Embodiment 1 lies only in that: a plurality of the vibration guide plates 12 and a plurality of the liquid outlets 11 are respectively arranged in one-to-one correspondence, a plurality of the vibration guide plates 12 are all of a hollow internal structure, and the liquid outlet 11 is communicated with the inside of the corresponding vibration guide plate 12, and a plurality of through holes 13 are further provided on the side wall of the vibration guide plate. Such a setting can further intensify the vibration effect of the cooling lubricant, so that the particle size of the formed liquid micro-particles is smaller and the cooling effect is better.

[0051] As Figure 6 shown in the figure, this embodiment discloses a composite metal plate rolling mill production line, and the rolling mill production line includes two groups of rolling mills arranged in sequence, and one of the groups of rolling mills is the composite metal plate rolling mill described in the above-mentioned Embodiment 1 or Embodiment 2.

[0052] Finally, it should be noted that: these embodiments are only used to illustrate the present invention and do not limit the scope of the present invention. In addition, for those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
