Thick-walled tube saddle port cutting mould, and formation method and application method thereof

Abstract

The invention discloses a thick-walled tube saddle port cutting mould, and a formation method and an application method thereof. The thick-walled tube saddle port cutting mould comprises an n-shaped supporting platform, wherein the supporting platform is provided with a trolley track, the trolley track is provided with a semi-automatic cutting machine trolley, a turning tire is arranged below the supporting platform, the turning tire is symmetrical to the centre and provided with two rollers used for supporting a thick-walled tube and driving the thick-walled tube to rotate, and a flame cutting nozzle on the semi-automatic cutting machine trolley is vertical to the wall of the thick-walled tube on the turning tire. The thick-walled tube saddle port cutting mould, provided by the invention, has the advantages of low cost, simple operation, easy implementation, good cutting effect and high processing quality, cutting of all kinds of curves on the thick-walled tube is lightly completed, the vices of poor manual cutting shape are avoided, the problems of too high price and the like caused by a numerical control abnormal cutting machine are avoided, and the quality requirements of sequential processes are ensured.

Description

technical field [0001] The invention relates to a cutting mold for saddle mouth of pipe fittings, more specifically, the invention relates to a mold for cutting saddle mouth of thick-walled pipe, its constitution and usage method. Background technique [0002] In actual production and application, the situation of pipe-pipe structure is often encountered, such as: T-shaped joints, K-shaped joints, Y-shaped joints of jackets, or the production of hoisting frames, etc., will involve the problem of pipe saddle cutting . [0003] The existing saddle mouth cutting methods include manual cutting and machine cutting, but these two methods have the following disadvantages and deficiencies respectively: [0004] (1) The shape of manual cutting is not good, the groove is uneven, and it is difficult to meet the quality requirements of the subsequent process; [0005] (2) Mechanical cutting can ensure a uniform groove shape, but the price of the CNC special-shaped cutting machine is t...

AI Technical Summary

Problems solved by technology

[0004] (1) The shape of manual cutting is not good, the groove is uneven, and it is difficult to meet the quality requirements of the subsequent process;

[0005] (2) Mechanical cutting can ensure a uniform groove shape, but the price of CNC special-shaped cutting machine is too high, which does not meet the actual requirements of production cost
