Description

Technical Field

[0002] Double-layer metal rolling is a technology that combines two or more different metals (or alloys) into a composite material with specific properties through a rolling process. Its core is to use the pressure and deformation during the rolling process to achieve metallurgical bonding (such as diffusion bonding) or mechanical bonding between different metal layers, thereby giving the material excellent comprehensive properties. Common metal rolling is generally the rolling of aluminum alloys, and the rolling method is generally hot rolling.

[0003] However, in the process of metal rolling, since the metal in the hot rolling operation has a certain temperature, the surface of the rolled metal will be easily oxidized. The oxidation of the metal surface during the rolling process may cause defects such as pitting and pitting on the metal surface, and the oxidized metal will have oxidized debris, which will affect the rolling quality between the metals. It may even cause cracks or delamination of the double-layer metal during the rolling process, which will affect the quality of the double-layer metal rolling.

[0025] Among them, the power connection assembly 11 includes a power longitudinal rod 1101 fixedly installed behind the corresponding transmission roller 8, and the rear end of the power longitudinal rod 1101 is fixedly installed with a second gear 1102 for meshing connection, and the opposite sides of the two second gears 1102 are commonly meshed and connected with a conversion gear 1103, and the inner wall of the conversion gear 1103 is rotatably connected to the surface of the rear support vertical plate 2 through a fixed shaft 1104, and the rod wall of the lower power longitudinal rod 1101 is located in front of the second gear 1102 and is fixedly installed with a second pulley 1105 for transmission, and the inner wall of the second pulley 1105 is clamped with the inner wall of the first pulley 504 through a clamping belt 1106. The surfaces of the two transmission rollers 8 located in front of the power longitudinal rod 1101 are fixed with several anti-slip strips 1107 for increasing friction. The anti-slip strips 1107 can better ensure the transportation of metal and ensure the normal rolling effect of the device.

[0026] The working principle of the above embodiment is: When the device is in use, the operator is required to place the two processed metals on the upper and lower transmission rollers 8 respectively. In this way, the metals can be transported and moved by the internally powered transmission rollers 8. The gas transported in the device's gas guide component 10 is nitrogen, which not only prevents oxidation of the metal surface but also does not affect the environment. The centralized vertical pipe 1002 in the gas guide component 10 will be connected to the nitrogen delivery equipment to ensure the supply of nitrogen required by the device. The device highlights the innovative structure and does not elaborate too much on the existing mature technologies and auxiliary gas delivery equipment. During the use of the device, the output motor 502 can drive the extrusion cylinder 4 to rotate relative to each other through the transmission longitudinal rod 3, so as to ensure the effect of extrusion and rolling of the two metals, and the output motor 502 can ensure the opposite rotation direction of the extrusion cylinder 4 through the mutual meshing effect of the first gear 503, thereby achieving the bite extrusion effect of the metal conveyed by the transmission roller 8, and the output motor 502 can transmit the rotational force to the power longitudinal rod 1101 through the pulley structure and the transmission of the belt 1106 under the rotation output. The power longitudinal rod 1101 is driven by the conversion gear. The rotation conversion of the wheel 1103 can ensure that the rotation directions of the upper and lower power longitudinal rods 1101 are the same, and the power source of the power longitudinal rod 1101 is provided by the lower transmission longitudinal rod 3, so that the rotation direction of the power longitudinal rod 1101 and the rotation direction of the lower transmission longitudinal rod 3 are consistent. If the metal plate on the left side is to be ensured to enter the extrusion cylinder 4 for rolling, the extrusion cylinder 4 on the lower side needs to be rotated clockwise, so the power longitudinal rod 1101 also rotates clockwise. Therefore, under the clockwise action of the power longitudinal rod 1101, the smooth transportation effect of the metal plate can be guaranteed. The rotation of the extrusion cylinder 4 will drive the internal transmission longitudinal rod 3 to rotate, and the clockwise rotation of the lower transmission longitudinal rod 3 will cause the upper transmission longitudinal rod 3 to rotate counterclockwise, and the counterclockwise rotation of the upper transmission longitudinal rod 3 will drive the L-shaped lever 506 on the output longitudinal rod 505 to rotate counterclockwise. During the counterclockwise rotation of the L-shaped lever 506, when the L-shaped lever 506 rotates to contact the pushing cylinder 1008, the L-shaped lever 506 will pull the pushing cylinder 1008 to move downward, so that the double-hole baffle 1003 will be driven downward through the L-shaped pull plate 1007, so that the inner wall of the double-hole baffle 1003 and the inner wall of the gas pipe 1001 are misaligned, which will reduce the delivery of nitrogen. As the L-shaped lever 506 continues to rotate, it will eventually move away from the pushing cylinder 1008. Under the elastic force of the spring 1005, The double-hole baffle 1003 will move upward again to ensure the re-alignment of the double-hole baffle 1003 and the inner wall of the gas pipe 1001, and restore the large-scale nitrogen delivery effect. The top surface of the double-hole baffle 1003 here contacts the upper side of the inner wall of the transmission chamber 6, so that the overlap effect of the holes of the double-hole baffle 1003 and the inner wall of the gas pipe 1001 can be ensured. The up and down movement of the double-hole baffle 1003 can ensure that the nitrogen is delivered to the delivery rod shell 7 intermittently, and the effect of switch delivery can be utilized to ensure that the nitrogen has the function of impact delivery. In this way, the cleaning bevel 702 on the delivery rod shell 7 is used to guide it out, so that if there are impurities on the surface of the metal plate, they will be blown away, and the blown nitrogen can also avoid the problem of oxidation of the metal surface, and use nitrogen adhesion to block oxygen to increase the quality of metal rolling.

[0027] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
