Description

Technical Field

[0001] The utility model relates to the technical field of polishing tubular hardware, in particular to a polishing device for tubular hardware. Background Art

[0002] Tubular hardware refers to metal products used in pipeline engineering. They are usually used to connect and install hardware accessories. Tubular hardware is made of various materials, and commonly used ones are alloy steel, stainless steel, copper, aluminum, etc. These materials are corrosion-resistant, high-temperature-resistant, and pressure-resistant, which makes tubular hardware widely used in various aspects of the manufacturing industry, such as mechanical processing, automobile manufacturing, and construction. Some tubular hardware often have burrs and flash on the inside and inner wall after processing, which can easily affect the actual use effect, and thus need to be polished inside.

[0003] The traditional grinding method is to grind manually with a handheld grinder, which results in a relatively low grinding efficiency. At the same time, manual grinding is prone to excessive force due to uneven force, which leads to wear of the inner wall surface of the hardware. When grinding tubular hardware, the grinding head of the grinding device first grinds the inner wall of the tubular hardware. After the inner wall is polished, the outer wall of the tubular hardware is polished. The overall grinding operation is relatively complicated and the grinding efficiency is low. At the same time, when grinding the outer wall, the clamped part of the tubular hardware is not polished, and the grinding effect is not good. The grinding operation needs to be repeated many times, which is inconvenient to use. Utility Model Content
