Description

A metal pipe end grinding device

technical field

The invention relates to the technical field of mechanical processing, in particular to a metal pipe end grinding device.

Background technique

Metal pipes are manufactured and sold in regular lengths of six meters, ten meters, twelve meters, etc. After purchase, the processing manufacturers need to process the steel pipes according to their own needs. The combination of columns and glass is used as guardrails in multi-storey shopping malls. When the column is manufactured, the two ends of the cut steel pipe need to be welded to the flange plate and the installation head for installing the handrail, and the installation frame for installing the glass is welded on the side wall of the steel tube. The glass needs to be supported for the column. It is made of steel pipe with a thickness greater than two millimeters. When the steel pipe is cut, burrs will be generated at the end, which will affect the subsequent welding. Since the cross section of the steel pipe is circular, the common burr scraper is inconvenient to use. It is not only impossible to control the amount of grinding with an angle grinder , and will quickly consume the physical strength of the operator.

If the pressure is small, the efficiency of non-grinding will be poor. The grinding wheel rotates around the steel pipe for a circle. Since the pressure of the telescopic oil cylinder of the grinding frame remains unchanged, the side wall of the steel pipe without burrs and burrs will be polished to the same degree, resulting in low consistency of steel pipe grinding. Therefore, it is necessary to design a metal pipe end Grinding device.
