Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe polishing equipment, and more specifically, to a small metal pipe inner diameter polishing head. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is aimed at obtaining a smooth surface or mirror gloss, and is sometimes used to eliminate gloss (matte). Polishing wheels are usually used as polishing tools. Polishing wheels are generally made of multiple layers of canvas, felt or leather, clamped on both sides by metal circular plates, and the wheel rims are coated with a polishing agent uniformly mixed with micro-powder abrasives and grease. During polishing, the high-speed rotating polishing wheel (circumferential speed of more than 20 m / s) is pressed against the workpiece, causing the abrasive to roll and slightly cut the workpiece surface, thereby obtaining a bright processed surface, and the surface roughness can generally reach Ra0.63~0.01 microns; when a non-greasy matte polishing agent is used, the bright surface can be matted to improve the appearance. When mass-producing bearing steel balls, the drum polishing method is often used. During rough polishing, a large number of steel balls, lime and abrasives are placed in an inclined can-shaped drum. When the drum rotates, the steel balls and abrasives randomly roll and collide in the drum to remove the surface convexity and reduce the surface roughness. The excess of about 0.01 mm can be removed. The inside of metal pipes also needs to be polished during polishing. The existing polishing heads for internal polishing of metal pipes have the following shortcomings: the size of the polishing head is fixed, and the polishing head needs to be replaced when polishing metal pipes with different aperture sizes, which is time-consuming and labor-intensive, and affects the production speed and the service life of the polishing head. In addition, the length of the polishing head of the current device is fixed, and it is inconvenient to polish the inner wall of metal pipes of different lengths. To solve the above problems, we have launched the following device. Utility Model Content
