Description

Technical Field

[0001] The utility model relates to the technical field of rolling of bimetallic composite materials, in particular to a roller structure for processing copper-aluminum composite plates. Background Art

[0002] With the development of modern science and technology, people are constantly putting forward higher requirements on the performance of materials. In most cases, it is difficult to meet the performance and cost requirements of engineering structures by using a single metal material. Bimetallic composite plates, such as copper-aluminum composite plates, are widely used in aerospace, mechanical power, electronic communications, home life and other aspects because of their excellent properties of cladding metal and base metal.

[0003] After searching, it was found that the publication number is CN108144966B, and the name is an electromagnetic vibration roller for rolling metal composite plates. The application proposes that in recent years, rolling bimetallic composite plates is usually divided into cold rolling and hot rolling. The strength and hardness of the bimetallic composite plates after cold rolling are significantly increased, but the plasticity and toughness are significantly reduced, accompanied by obvious work hardening phenomenon. The plate must be annealed after rolling, which is bound to greatly increase energy consumption and reduce production efficiency. In addition, the higher rolling force during cold rolling is likely to cause rolling mill bounce and roll deflection deformation. Hot rolling has many problems such as difficult size control, low strength index, large performance fluctuation range, poor surface quality, and excessive temperature will also cause grain growth. By introducing an ultrasonic vibration device in the rolling process, ultrasonic vibration helps the metal plate to obtain energy and improve the activity of the plate. High-frequency vibration can break the oxide film on the contact surface of the bimetallic plate, expose more fresh metal, promote dislocation migration inside the metal, refine the grains, and improve the bonding strength of the bimetallic composite plate. The vibration device generates high-frequency vibration, which intensifies the movement of metal particles, increases the temperature, reduces internal friction, and converts the lost vibration energy into heat energy, causing the temperature inside the medium to rise, effectively improving the plastic deformation capacity of the bimetal. At the same time, high-frequency vibration can reduce stress concentration and eliminate surface microcracks during the rolling process. However, this application installs the electromagnetic vibrator inside the roller and uses it with a variety of sensors. The structure is very complex. Due to the poor working environment of the rolling process, the precision electromagnetic vibrator and a variety of sensors are very easy to be damaged, the manufacturing and use costs doubled, and the installation and debugging are also more troublesome. At the same time, it is difficult to disassemble for later inspection and maintenance, and maintenance is troublesome. It also requires a complex power supply structure such as rotating power supply, which further increases the complexity and cost of installation. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

When the aluminum composite plate is rolled, the driving device drives the driving wheel 4 to rotate, and then drives the roller 1 to rotate through the main shaft 3 to roll the copper-aluminum composite plate.

As the roller 1 rotates, the side tube 7 rotates with the inner tube 6. When the side tube 7 rotates to the other end of the top mouth, the steel ball 8 moves down and the spring 11 is compressed. When the side tube 7 rotates to the other end downward, the spring 11 rebounds and the steel ball 8 moves down synchronously through the gravity, hitting the inner wall of the roller 1 to generate vibration. The vibration helps the copper-aluminum composite plate to obtain energy, improve the activity of the copper-aluminum composite plate, and can It is able to break the oxide film on the surface of the copper-aluminum composite plate by vibration, promote the internal displacement of the metal, and improve the bonding strength of the copper-aluminum composite plate.
