Background technique

Pipe is the material used to make pipe fittings. Different pipes use different pipes. The quality of pipes directly determines the quality of pipes. Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drain pipes, gas pipes, and heating pipes. Tubes, wire conduits, rainwater pipes, etc., the cylindrical grinding of pipes is an important part of pipe machining.

At present, the grinding of most pipe fittings is carried out in the grinding machine, but the grinding machine has many significant deficiencies, such as: 1. Most of the ordinary grinding machines can only process shorter pipe fittings, but not long pipe fittings; 2. In the grinding machine When grinding pipe fittings, the pipe fittings are generally clamped for processing, and the clamping structure is complicated; third, the cost of the grinding machine is relatively high. The existing equipment for processing long pipes is basically to manually adjust the feed rate, and manually measure after grinding. This method makes the processing efficiency low, time-consuming and labor-intensive. For this reason we propose a kind of mechanical steel pipe outer surface grinding processing device.
