Description

Technical Field

[0001] The invention relates to the field of round tube marking moulds, in particular to a round tube notch marking mould with a fixed plane added as a reference plane. Background Art

[0002] Pipe cutting is an important step before pipeline installation. The pipe needs to be cut according to the length and shape required for installation.

[0003] During production and construction, it is often necessary to seal and place a vertical pipe between two parallel horizontal pipes. At this time, arc-shaped notches with the same diameter as the horizontal pipe need to be cut at both ends of the vertical pipe. Because the two horizontal pipes are parallel, the two arc-shaped notches need to be cut on the same reference plane. However, since the circular pipe surface of the circular pipe itself does not have a reference plane for reference, large errors are likely to occur during cutting. Summary of the invention

[0004] The object of the present invention is to provide a circular tube notch marking die with an additional fixed plane as a reference plane, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a circular tube notch marking mold with a fixed plane added as a reference plane, comprising a marking mold, the marking mold is a split design, including an alignment mold and a limiting mold, and the inner diameters of the alignment mold and the limiting mold are the same.

[0006] Preferably, a first placement groove is provided on the surface of the alignment mold, the first placement groove is an open semi-cylindrical design, and one end of the first placement groove is fixedly connected to a limiting protrusion.

[0007] Preferably, the limiting mold includes an upper cover plate, a lower cover plate, a first arc groove, a second arc groove and a second placement groove, the upper cover plate is covered and installed on the top of the lower cover plate, the first arc groove is opened at the front end of the upper cover plate, the second arc groove is opened at the front end of the lower cover plate, and the second placement groove is opened inside the upper cover plate and the lower cover plate.

[0008] Preferably, the bottom ends of the alignment mold and the limiting mold are both designed to be flat planes.

[0009] Preferably, the protruding cutout formed by the second arc-shaped groove and the second placement groove corresponds to the limiting protrusion.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The present invention proposes a circular tube notch marking mold with an added fixed plane as a reference plane. The mold can use an alignment mold to fix the circular tube after the rear end is cut, and then a limiting mold is sleeved on the surface of the circular tube for secondary fixation. The position is determined by sliding the limiting mold on the surface of the circular tube, and the protrusion at the front end of the limiting mold is used to facilitate the marking process on the surface of the circular tube, so as to ensure that the position of the front end of the circular tube when cut can be maintained on the same horizontal plane as the rear end.

[0024] See also Figures 1 to 5 The present invention provides a technical solution: a circular tube notch marking mold with a fixed plane added as a reference plane, comprising a marking mold 1, the marking mold 1 is a split design, comprising an alignment mold 2 and a limiting mold 3, the alignment mold 2 and the limiting mold 3 have the same inner diameter;

[0025] The mold can use the alignment mold 2 to fix the round tube after the rear end is cut, and then the limiting mold 3 is set on the surface of the round tube for secondary fixing. The position is determined by sliding the limiting mold 3 on the surface of the round tube, and the protrusion at the front end of the limiting mold 3 is used to facilitate the drawing process on the surface of the round tube, so as to ensure that the position of the front end of the round tube when cutting can be kept on the same horizontal plane as the rear end;

[0026] A first placement groove 22 is provided on the surface of the alignment mold 2. The first placement groove 22 is an open semi-cylindrical design. One end of the first placement groove 22 is fixedly connected to the limiting protrusion 21.

[0027] The limiting mold 3 includes an upper cover plate 31, a lower cover plate 32, a first arc groove 33, a second arc groove 34 and a second placement groove 35. The upper cover plate 31 is covered and installed on the top of the lower cover plate 32. The first arc groove 33 is opened at the front end of the upper cover plate 31, the second arc groove 34 is opened at the front end of the lower cover plate 32, and the second placement groove 35 is opened inside the upper cover plate 31 and the lower cover plate 32.

[0028] When in use, the position after cutting the rear end of the round tube is inserted into the limiting protrusion 21 of the alignment mold 2, and then the upper cover plate 31 and the lower cover plate 32 of the limiting mold 3 are covered on the front end of the round tube, and then the limiting mold 3 is slid on the surface of the round tube. After determining the appropriate cutting position, use an oil pen to mark the surface of the round tube along the second arc groove 34 and the second placement groove 35. The marked front end of the round tube and the cut rear end of the round tube are located in the same plane, so it is not easy to make errors in subsequent cutting;

[0029] The bottom ends of the alignment mold 2 and the limiting mold 3 are both designed to be flat surfaces;

[0030] The plane-designed alignment mold 2 and the limiting mold 3 can ensure that the front and rear ends of the round tube are in the same horizontal plane when marking, thus reducing the error during marking;

[0031] The protruding cutout formed by the second arc groove 34 and the second placement groove 35 corresponds to the limiting protrusion 21;

[0032] The corresponding raised cutouts and the limiting protrusions 21 can ensure that the front and rear ends of the round tube are at the same angle during cutting, thereby reducing errors.
