Special-shaped tube bending tool

Abstract

The invention discloses a special-shaped tube bending tool, wherein a special-shaped tube is used for forming various cylindrical reaction chambers, and a plurality of special-shaped tube bending tools are required and are at least 1 / 4 of special-shaped tubes required by a cylindrical reaction chamber. Each set of special-shaped tube bending tool comprises at least one first runner, at least two second runners and a support frame, wherein the first runner and the second runners are arranged on the support frame; arc grooves formed in the special-shaped tubes corresponding to the first runner and the second runners; and the special-shaped tubes are contained in the adjacent arc grooves of the first runner and the second runners. The special-shaped tube bending tool disclosed by the invention bend the special-shaped tubes accurately and rapidly according to design demands and can improve the bending accuracy and speed of the special-shaped tubes and the production accuracy and efficiency of a gasifier.

Description

technical field [0001] The invention relates to the field of chemical, petroleum and other production equipment manufacturing, in particular to a special-shaped pipe bending tool used for bending special-shaped pipes forming a cylindrical reaction chamber. Background technique [0002] Gasifiers used in petroleum, chemical and other industrial fields are complex in structure and bulky compared to ordinary gasifiers, so the manufacturing process of gasifiers used in petroleum, chemical and other industrial fields is also obviously different from ordinary gasifiers. Production of gasifiers. For example, the cylindrical reaction chamber of the gasifier is a membrane wall in the shape of a curved 45° elbow composed of 64 Ω tubes (that is, special-shaped tubes); similarly, many other parts of the gasifier also have different bending It is formed by group welding of special-shaped tubes with angles. [0003] Therefore, the bending operation of various special-shaped pipes has be...

Problems solved by technology

[0003] Therefore, the bending operation of various special-shaped pipes has become an indispensable step in the gasifier manufacturing process, but there is no special bending tooling for bending special-shaped pipes used in gasifiers in the prior art, so that the whole The bending process of special-shaped pipes is cumbersome and inconvenient to operate. It takes a lot of time to bend special-shaped pipes, and the precision of the bent special-shaped pipes usually does not meet the design requirements; this not only affects the production speed of the entire gasifier, but also Moreover, the production quality of the whole gasifier cannot be guaranteed
