Elbow blanking and marking tool and application method thereof

Abstract

The invention provides an elbow blanking and marking tool and an application method thereof and overcomes the shortcoming about manual marking on the ground in the prior art. The marking tool comprises a straight pole (1), a connecting base (2), a tightening spring (3), a slider (4) and a paintbrush (5). The straight pole (1) and the connecting base (2) are perpendicular to each other and welded integrally, the slider (4) is connected with the connecting base (2) through a built-in slideway of the connecting base (2) and can slide on the slideway; before marking, the outer end of the straight pole (1) is abutted against the edge of the elbow, the connecting base (2) guarantees levelness with the ground, and the slider (4) and the connecting base (2) as well as the paintbrush (5) are fixed through the tightening spring (3), so that the tip of the paintbrush (5) and the outer end of the elbow are on the same vertical plane, and an outline of the elbow after shaped can be obtained by marking along the outer outline of the elbow. The elbow blanking and marking tool and the application method thereof are used for secondary marking-off in blanking of the elbow, all required graphics can be accurately marked rapidly, labor intensity is lowered, and efficiency is improved; the elbow blanking and marking tool is simple in structure, convenient to manufacture and convenient to use.

Description

technical field [0001] The invention is applied to the scribing of bent pipe blanking in the production of machinery manufacturing industry. Background technique [0002] In the oil refining and chemical machinery manufacturing industries, most equipment has bent pipes, and bending pipe cutting is frequently encountered, and it is also a difficult point. The existing technology is to draw lines manually on the ground, which often has large errors, insufficient precision, complicated operation, and high requirements on the technical level of workers. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art, and provide a fast, accurate, convenient operation, improved efficiency and accuracy of the elbow blanking marking tool. [0004] The invention provides a marking tool for bending pipe blanking, the solution is: the marking tool includes a straight rod 1, a connecting base 2, a faste...
