Description

Technical Field

[0001] The invention relates to the technical field of rolling composite equipment, and in particular to non-ferrous metal composite plate and strip rolling equipment. Background Art

[0002] Metal composite plates combine the advantages of each component metal and have physical and chemical properties that a single metal does not have. They are widely used in aerospace, national defense, transportation, equipment manufacturing and other fields. The promotion and application of metal composite plates is of great significance to solving the outstanding problems of the current energy structure and industrial structure.

[0003] At present, the main methods for preparing metal composite plates include rolling, extrusion, explosion and diffusion welding. The rolling method is one of the most widely used preparation methods. The metal plate to be composited is subjected to the strong rolling pressure of the rolling mill to break the coating on the contact surface of the dissimilar metals, and plastic flow is generated in the entire contact surface. The fresh base metal squeezed out from the surface cracks comes into close contact and produces microscopic atomic reactions, and finally the contact interface between the metal layers forms a metallurgical bond of a certain strength. Compared with other methods, the rolling method has the advantages of low pollution, stable operation and good continuity of mass production.

[0004] During the rolling process of non-ferrous metal composite plates and strips, heat is generated when the metal undergoes transverse plastic deformation, and the friction between the rollers and the metal also generates heat. Different metal materials have different sensitivities to temperature. Lower temperatures may cause the composite plate to crack and the metal plate to fail to composite. In addition, high temperatures may reduce the hardness of the rollers and cause warping in the middle, resulting in the metal composite plate being thick in the middle and thin on both sides after rolling. Hollow rollers are used, and the heat exchange between the heat exchange oil and the rollers is used to control the roller temperature. Affected by the temperature transfer efficiency, the roller rotation speed cannot be too fast. Too fast will cause heat accumulation, resulting in low rolling efficiency. Increasing the ratio of the inner diameter of the oil channel to the roller radius will reduce the roller's bending resistance. Setting up an oil channel near the edge of the roller can improve the heat exchange efficiency, but the uneven surface temperature of the roller will reduce the rolling quality. Summary of the invention

[0005] In order to make up for the above deficiencies, the present invention provides a non-ferrous metal composite plate and strip rolling equipment.

[0006] The technical solution of the present invention is:

[0007] A non-ferrous metal composite strip rolling equipment, comprising:

[0009] The temperature control assembly includes two groups of temperature control rollers, and second rotary joints are rotatably installed at both ends of the temperature control rollers. The second rotary joints are used to pass heat exchange fluid into the temperature control rollers to control the temperature of the temperature control rollers. The temperature control rollers are used to perform heat exchange with the roller assembly;

[0010] The pre-pressing assembly includes a height adjustment assembly, the top surface of which is provided with a pressing assembly, the pressing assembly is used to press different metal raw materials and change the height of the metal strip to make it flush with the center of the roller assembly;

[0013] Preferably, the rolling roller comprises a roller body, with roller heads at both ends of the roller body, oil passages are provided through the roller body and the roller head, and a first rotary joint is provided outside the roller head.

[0014] Preferably, the temperature control roller is symmetrically installed on the front and rear sides of the roller through a connecting frame, the temperature control roller is in contact with the middle roller at the same height, and the temperature control roller is close to the working roller but not in contact with the working roller.

[0015] Preferably, the temperature control roller includes a rotating shaft, a heat exchange barrel is provided between the rotating shafts, the heat exchange barrel is hollow and the inner diameter of the heat exchange barrel is larger than the oil channel, a through hole is provided through the rotating shaft, and the second rotary joint is threadedly installed on the outside of the rotating shaft.

[0020] 1. The present invention arranges hollow temperature control rollers on the front and rear sides of the roller, passes a relatively high temperature heat exchange fluid into the front temperature control roller, and passes a low temperature heat exchange fluid into the rear temperature control roller. The front temperature control roller transfers heat to the roller, thereby controlling the temperature of the roller when in contact with the metal material, meeting the temperature requirements of different materials. The rear temperature control roller is used to absorb the heat on the surface of the roller, avoids the accumulation of temperature on the surface of the roller, and reduces the deformation of the roller.

[0021] 2. Since the temperature control roller is always in contact with the roller, the surface temperature of the roller is uniform. At the same time, since the temperature control roller does not need to be in contact with the material, the thickness of the heat exchange barrel can be made very thin, which is conducive to improving the heat transfer efficiency, thereby meeting the temperature control of the roller for rapid rolling and improving the rolling efficiency;

[0022] 3. By setting up the pre-pressing assembly, using the fixed roller and the adjusting roller to press the metal material, and using the height adjustment group to adjust the height of the pre-pressing bracket, different materials can be pre-pressed to ensure that the material enters horizontally between the two rollers, effectively improving the rolling efficiency and avoiding contact between the material and the temperature control roller;

[0023] 4. By setting up the deviation correction component and utilizing the elastic force of the elastic part, pressure is applied to the metal material through the centering roller, so that the position of the metal material is maintained in the middle of the fixed roller and the adjusting roller, ensuring that the metal material enters between the rollers from the middle position after being pressed by the fixed roller and the adjusting roller to achieve the best rolling effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0039] The present invention describes the above technical solution in detail through the following embodiments:

[0040] Embodiment 1:

[0041] See attached Figure 1-8 , a non-ferrous metal composite strip rolling equipment, comprising:

[0042] The rolling mill 1 comprises a frame 11, a roller assembly is slidably mounted inside the frame 11, a temperature control assembly 2 is arranged on the front and rear sides of the roller assembly, a pre-pressing assembly 3 is arranged on the front side of the frame 11, and a deviation correction assembly 4 is arranged on the front side of the pre-pressing assembly 3.

[0043] Roller assemblies are used to roll several layers of non-ferrous metal into metal strip.

[0044] The roller assembly includes two pressure rollers 15 , between which two working rollers 16 are rotatably mounted, and between which two working rollers 16 , two rolling rollers 17 are rotatably mounted, and the rolling rollers 17 are used for rolling metal materials.

[0045] One end of the working roll 16 is connected to a driving device via a retractable universal joint. The driving device may be a known three-phase motor. When the motor is working, it can drive the working roll 16 to rotate via the universal joint, thereby driving the roller 17 to rotate via friction.

[0046] The working roll 16 and the rolling roll 17 in contact with each other are connected by the same bracket, and the working roll 16 and the rolling roll 17 are slidably connected to the frame 11. A known nitrogen spring is provided between the working roll 16 and the brackets at both ends of the working roll 16, and the nitrogen spring is used to drive the two working rolls 16 to separate from each other. The two pressurized oil cylinders 13 are used to squeeze the working roll 16 toward the middle, which can reduce the vibration of the working roll 16 when it rotates, and can also reduce the deformation of the working roll 16 and the rolling roll 17 during rolling.

[0047] A balancing assembly 12 is connected above the upper pressure roller 15, and the balancing assembly 12 is used to prevent the pressure roller 15 from tilting. A pressure cylinder 13 is fixedly installed in the center of the top surface of the frame 11 by bolts, and the piston rod of the pressure cylinder 13 penetrates downward through the frame 11 and is connected to both ends of the pressure roller 15 by bolts. When the pressure cylinder 13 is working, it can drive the pressure roller 15 to move in the vertical direction, thereby changing the height of the working roller 16 above.

[0048] A lifting assembly 14 is provided below the pressurized oil cylinder 13 below. The lifting assembly 14 consists of two triangular sliders and two hydraulic cylinders. When the two hydraulic cylinders are working, they can drive the two triangular sliders to slide, thereby changing the overall height of the two sliders, so that the height of the pressurized oil cylinder 13 below changes, and then changes the height of the working roller 16 below.

[0049] The roller 17 includes a roller body 172 , with roller heads 171 at both ends of the roller body 172 , an oil passage 173 passing through the roller body 172 and the roller head 171 , and a first rotary joint 18 is externally threadedly connected to the roller head 171 .

[0050] The roller body 172 and the roller head 171 are integrally formed. The first rotary joint 18 is used to introduce heat exchange fluid into the oil passage 173, and the heat exchange fluid is preferably oil.

[0051] Heat exchange fluid is introduced into the oil passage 173, and by controlling the temperature of the heat exchange fluid, the temperature inside the roller 17 can be controlled. At the same time, the first rotary joint 18 is provided at both ends to speed up the flow rate of the heat exchange fluid and improve the stability of temperature control.

[0052] The temperature control assembly 2 includes two groups of temperature control rollers 26. Second rotary joints 27 are threadedly installed at both ends of the temperature control rollers 26. The second rotary joints 27 are used to pass heat exchange fluid into the temperature control rollers 26 to control the temperature of the temperature control rollers 26. The temperature control rollers 26 are used to exchange heat with the rolling roller assembly.

[0053] There are four temperature control rollers 26 in total, each group of temperature control rollers 26 has two temperature control rollers, the two temperature control rollers 26 in the same group have the same height, the two temperature control rollers 26 in the same group have different temperatures of heat exchange fluids, and the heat exchange fluid in the temperature control rollers 26 is preferably oil.

[0054] The temperature control roller 26 is symmetrically installed on the front and rear sides of the roller 17 through the connecting frame 21. The temperature control roller 26 is attached to the middle roller 17 at the same height. The temperature control roller 26 is close to the working roller 16 but does not contact the working roller 16.

[0055] The temperature of the heat exchange fluid in the front temperature control roller 26 is relatively high, slightly higher than the contact temperature required for metal rolling, and the temperature of the heat exchange fluid in the rear temperature control roller 26 is relatively low, but not lower than room temperature by more than 10°C to avoid condensation on the surface.

[0056] The temperature control roller 26 includes a rotating shaft 261, between which a heat exchange barrel 262 is welded. The heat exchange barrel 262 is hollow and the inner diameter of the heat exchange barrel 262 is larger than the oil passage 173. A through hole 263 is provided in the rotating shaft 261, and the second rotary joint 27 is threadedly installed on the outside of the rotating shaft 261.

[0057] The temperature control roller 26 does not contact the material, and the barrel wall thickness of the heat exchange barrel 262 can be made very thin to improve the heat transfer efficiency. The heat exchange fluid can enter through the second rotary joint 27 on one side, enter the heat exchange barrel 262 through the through hole 263, and then be discharged from the second rotary joint 27 on the other side. By controlling the temperature of the heat exchange fluid, the temperature of the heat exchange barrel 262 can be controlled, thereby controlling the contact temperature between the roller 17 and the material, and taking away the residual heat on the surface of the roller 17 after rolling.

[0058] The roller 17 is rotatably connected to the connecting frame 21 via a bearing, and the connecting frame 21 is fixedly connected to brackets at both ends of the roller 17 via bolts or the like, thereby preventing the connecting frame 21 from rotating.

[0059] Mounting grooves 22 are provided on both sides of the connecting frame 21, and an adjusting slider 24 is slidably installed in the mounting grooves 22. An adjusting plate 23 is fixedly installed at the opening of the mounting grooves 22 by bolts. An adjusting bolt 25 is threadedly installed on the adjusting plate 23. The adjusting bolt 25 passes through the adjusting plate 23 and is rotatably connected to the adjusting slider 24. The rotating shaft 261 is inserted into the mounting groove 22 and is rotatably connected to the adjusting slider 24 through a bearing.

[0060] By rotating the adjusting bolt 25 , the adjusting slider 24 can be driven to move, thereby controlling the pressure of the adjusting slider 24 on the rotating shaft 261 , and further controlling the pressure of the heat exchange barrel 262 on the roller 17 .

[0061] When the adjusting slider 24 is no longer in contact with the rotating shaft 261 , the temperature control roller 26 loses its fixation and can be removed.

[0062] The pre-pressing assembly 3 comprises a height adjusting assembly, the top surface of which is provided with a clamping assembly, which is used to clamp different metal raw materials and change the height of the metal strip to make it flush with the center of the roller assembly.

[0063] The height adjustment assembly includes a lifting frame 31 , which is slidably mounted on the front side of the frame 11 , and a lifting cylinder 32 is disposed at the bottom of the lifting frame 31 , which is used to drive the lifting frame 31 to move in a vertical direction.

[0064] A lifting guide rail 33 is symmetrically fixedly installed on the front side of the frame 11 by bolts, and the lifting frame 31 and the lifting guide rail 33 are slidably connected.

[0065] By controlling the operation of the lifting cylinder 32 , the height of the lifting frame 31 can be changed.

[0066] The clamping assembly includes two pre-pressing brackets 34 , between which a fixed roller 36 is rotatably mounted via a bearing, above which an adjusting roller 37 is slidably mounted, and both ends of the adjusting roller 37 are connected to an adjusting cylinder 39 via a second slider 38 .

[0067] The pre-stressing bracket 34 is fixedly installed on the middle part of the top surface of the lifting frame 31 by bolts. A slide groove 35 is provided in the middle part of the pre-stressing bracket 34. The adjusting roller 37 slides in the slide groove 35 through the second slider 38. The fixed roller 36 is located below the adjusting roller 37. The adjusting cylinder 39 is fixedly installed on the top surface of the pre-stressing bracket 34 by screws. The piston rod of the adjusting cylinder 39 passes through the pre-stressing bracket 34 and is rotatably connected to the second slider 38.

[0068] By controlling the adjusting oil cylinder 39 to work, the second slider 38 can be driven to slide along the slide groove 35 , thereby changing the height of the adjusting roller 37 , and further changing the distance between the adjusting roller 37 and the fixed roller 36 .

[0069] The metal material thus enters between the adjusting roller 37 and the fixed roller 36, and is squeezed by the adjusting roller 37 and the fixed roller 36 to complete preliminary straightening. By operating the lifting cylinder 32, the height of the lifting frame 31 is changed, and the height of the extruded metal material can be changed, so that the metal material can enter horizontally between the rollers 17, thereby improving the rolling efficiency and rolling effect.

[0070] The deviation correction assembly 4 includes two centering rollers 42, and the backs of the two centering rollers 42 are connected to pressure assemblies. The centering rollers 42 are used to squeeze the metal raw material from both sides to ensure that the metal raw material is located in the center of the clamping assembly.

[0071] The two centering rollers 42 are kept in a vertical state, and their axes are perpendicular to the axes of the adjusting roller 37 and the fixed roller 36 .

[0072] The pressure assembly includes a centering frame 41, on the back of which two guide rods 43 are welded. The guide rods 43 are slidably installed on the front side of the pre-pressure bracket 34 through a guide frame 44. An elastic member 45 is sleeved on the guide rod 43 and located between the guide frame 44 and the centering frame 41. The centering roller 42 is rotatably installed on the opening side of the centering frame 41.

[0073] The elastic member 45 can be a spring, and the elastic force of the elastic member 45 can drive the centering rollers 42 to approach each other, thereby squeezing the metal material from both sides to align the metal material and keep it at the center position of the adjustment roller 37 and the fixed roller 36.

[0074] The guide rod 43, the guide frame 44 and the elastic member 45 can be replaced with a nitrogen spring.

[0075] When the operator of this embodiment uses the device, he pulls different nonferrous metal coils out from the material rack, keeps them horizontal and passes them through between the centering rollers 42. After being squeezed by the centering rollers 42, the different materials remain horizontal.

[0076] The adjusting cylinder 39 is controlled to work, driving the second slider 38 to slide along the slide groove 35, changing the height of the adjusting roller 37, allowing the aligned material to pass between the adjusting roller 37 and the fixed roller 36, and then the adjusting cylinder 39 is controlled to work, driving the adjusting roller 37 to cooperate with the fixed roller 36 to press the metal material.

[0077] The lifting cylinder 32 is controlled to work and the height of the lifting frame 31 is changed so that the material squeezed by the adjusting roller 37 and the fixed roller 36 is kept level with the roller 17 .

[0078] The working roll 16 is driven to rotate by a driving device such as a motor, thereby controlling the rotation of the rolling roll 17.

[0079] The heat exchange fluid is passed through the roller 17 through the first rotary joint 18 to change the internal temperature of the roller 17. At the same time, the heat exchange fluid is passed through the temperature control roller 26 through the second rotary joint 27 to ensure that the temperature of the front temperature control roller 26 is slightly higher than the rolling temperature requirement of the material, and the temperature of the rear temperature control roller 26 is slightly lower than the room temperature. The temperature of the heat exchange fluid in the front temperature control roller 26 is controlled according to the different rolling materials.

[0080] The material squeezed by the adjustment roller 37 and the fixed roller 36 is inserted between the rollers 17 .

[0081] The pressurized oil cylinder 13 and the lifting assembly 14 are controlled to work, the height of the roller 17 is changed, and rolling is started.
