Abstract
The invention relates to a line drawing instrument for oxygen cutting of a pipe fitting. Generally, a linear edge is cut by using loft paper when a steel pipe is cut and blanked by an oxygen cutting gun; and the linear edge is encircled and overlapped around the outer surface of the pipe fitting; then the line drawing operation is carried out. In the general process, the operation is more complicated, the drawing deflection is easily caused, and the speed is slower. When in use, the line drawing instrument for the steel pipe is arranged on the outer surface of the pipe fitting, four wheels cling to the outer surface of the pipe fitting, a line drawing frame points to the direction of a pipe opening, then the pipe fitting is rolled or the line drawing instrument is pushed, a straight line is drawn on the outer surface of the pipe fitting until the pipe fitting is rolled for a circle, the straight line is connected to the line drawing start, and the line drawing operation is ended. In the above process, the operation is simple, the line can be drawn accurately, and the speed is fast. The line drawing instrument for the steel pipe is a tool which not only increases the blanking speed in a processing procedure but also improves the processing quality for processing medium and small batches of pipe fittings. Moreover, the line drawing instrument can be subjected to auxiliary application in the process of cutting all the pipe fittings.
Description
Technical field the present invention relates to the line-drawing instrument of oxygen cutting pipes
When background technology is blocked the steel pipe blanking with the oxygen burning torch usually, adopt setting-out paper to shear out the straight line limit.Around pipe fitting outer surface, make straight line center on coincidence, carrying out setting-out then.The pipe fitting bottom also needs apart from the ground certain height when centering on.Operate more loaded down with trivial detailsly, it is inclined to one side to be prone to picture, and speed is slower.
Be to solve the setting-out in the oxygen cutting pipes process, the setting-out error that is produced effectively improves the cutting accuracy and the operating efficiency of cutting pipes, avoids occurrence of waste and defect ware in cutting process.Developed steel pipe scriber appearance.
Summary of the invention the objective of the invention is to overcome the deficiency of prior art, and a kind of accurately line tool efficiently is provided.Its structure utilizes parallel principle and man-computer relation to design, and can adapt to the setting-out of blocking of all pipe fittings.
Description of drawings 1. body frames.2. directive wheel.3. adjustment screw.4. scribing block.5. setting-out bar.6. slate pencil steps up device.7. holding screw.
The specific embodiment in use, with the outer surface of line-drawing instrument frame in pipe fitting, four-wheel is close to outer surface of pipe fittings; Scribing block points to the direction of the mouth of pipe, and the pipe fitting or promote line-drawing instrument of rolling then draws straight line up to rolling a week at the outer surface of pipe fitting; Be connected to starting of setting-out, line finishes.
Claims (4)
