Aluminum alloy section mechanical polishing device

Abstract

The invention discloses an aluminum alloy section mechanical polishing device. The aluminum alloy section mechanical polishing device comprises a machine body, wherein a moving cavity is arranged in the machine body, a moving block is arranged in the moving cavity in a sliding mode, a hydraulic cylinder is fixedly arranged on the moving block, telescopic shafts are arranged at the left end and theright end of the hydraulic cylinder, an installation rod is fixedly arranged at one end, far away from the moving block, of each telescopic shaft, and a polishing device is arranged in each installation rod. Two polishing rotary wheels symmetrical left and right and a driving wheel are arranged, polishing belts with polishing abrasive paper are in power connection between the polishing wheels andthe driving wheel, an aluminum alloy is processed through the rotation of the polishing belts, and the left polishing rotary wheel and the right polishing rotary wheel can be reasonably adjusted according to the size of an actual operation interval and the size of a polished area of the to-be-polished aluminum alloy, so that the space size of the device is reduced, and the use flexibility of thedevice is improved. Moreover, the five polishing belts between the polishing rotary wheels and the driving wheel have different fineness, the polishing belts are automatically replaced, the operationis simple and convenient, and the applicability is wide.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to a mechanical polishing device for aluminum alloy profiles. Background technique [0002] Aluminum is a metal with low strength and good plasticity. In addition to the application of some pure aluminum, in order to improve the strength or comprehensive performance, it is widely used in combination with aluminum alloy. During the manufacturing process of aluminum alloy, the surface needs to be polished and polished. The existing aluminum alloy Polishing can be processed by a special aluminum alloy polishing machine, but because the polishing machine is expensive, large in size, and small in scope of application, it increases the production cost of aluminum alloys, and the smaller aluminum alloys not only have poor processing effect by using a polishing machine, but in addition , usually use sandpaper or grinding wheel to polish the surface of aluminum alloy. When polishing,...

[0002] Aluminum is a metal with low strength and good plasticity. In addition to the application of some pure aluminum, in order to improve the strength or comprehensive performance, it is widely used in combination with aluminum alloy. During the manufacturing process of aluminum alloy, the surface needs to be polished and polished. The existing aluminum alloy Polishing can be processed by a special aluminum alloy polishing machine, but because the polishing machine is expensive, large in size, and small in scope of application, it increases the production cost of aluminum alloys, and the smaller aluminum alloys not only have poor processing effect by using a polishing machine, but in addition , usually use sandpaper or grinding wheel to polish the surface of aluminum alloy. When polishing, different degrees of aluminum alloy need to be polished to different degrees of fineness. The existing mechanical polishing device has a fixed structure, and the size cannot be adjusted according to the use environment and the aluminum alloy to be polished. The polishing area is adjusted, which is inconvenient to use, and it is inconvenient to operate when replacing sandpaper or grinding wheels of different finenesses, which reduces the work efficiency for aluminum alloy polishing
