Elbow pipe processing technology

Abstract

The invention discloses an elbow pipe processing technology. The elbow pipe processing technology is used for processing an elbow pipe with a first pipe opening and a second pipe opening, wherein thefirst pipe opening is provided with a flange plate, the opening edge of the first pipe opening is higher than the flange plate, and an axis of the first pipe opening is perpendicular to an axis of thesecond pipe opening mutually. The elbow pipe processing technology comprises the following steps: step one: fixing the elbow pipe on a first clamp and lathing a first pipe opening outer circle; steptwo: fixing the first pipe opening of the elbow pipe on a second clamp and lathing a second pipe opening inner circle; step three: fixing the elbow pipe on a third clamp, and drilling a hole in the flange plate; using the flange plate to position on the first clamp, firstly processing the first pipe opening outer circle provided with the flange plate, and using a positioning ring on the second clamp to position the first pipe opening of the elbow pipe and process the second pipe opening outer circle, using the flange plate to position, and using a drill bushing to process the hole in the flange plate. The processing sequence is optimized, the processing steps are simplified, the clamping and positioning accuracy is higher, and the production efficiency of the elbow pipes is greatly improved.

Description

technical field [0001] The invention relates to a pipe bending process. Background technique [0002] In the prior art, when processing an elbow with a first nozzle and a second nozzle, and the first nozzle is provided with a flange, and the edge of the first nozzle is higher than the flange, due to the need to process There are many positions, not only need to process the outer circle of the first nozzle and the second nozzle, but also need to process the holes on the flange, there are shortcomings such as inaccurate clamping and positioning, complicated procedures, etc., which affect the production efficiency of the product . Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a pipe bending process that is accurate and convenient in positioning and clamping, and can effectively improve the efficiency of pipe bending processing. [0004] The technical solution of the present invention is: a pipe bending proc...
