Technical Field
[0001] This utility model relates to the field of elbow end processing technology, and in particular to a fixture for elbow end processing. Background Technology
[0002] Elbows are pipe fittings used in piping systems to change the direction of pipelines. The most common type is the 90° elbow, but there are also non-90° elbows, mainly with an angle of 45°, as well as elbows with other angles required for special projects. Currently, when processing elbows, it is necessary to clamp and position them, which often requires two sets of clamps. However, the two sets of clamps are usually fixed and difficult to adjust in angle, so they cannot adapt to elbows with different curvatures. At the same time, it is impossible to control the clamping force, which leads to the problem of extrusion damage to the pipe surface. Therefore, we have redesigned a clamp for processing the ends of elbows. Utility Model Content
