The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic structural view of a piercing plug for seamless steel pipe production according to the present invention;
fig. 2 is an enlarged view of a in fig. 1.
In the figure, 1, a head part of a plug, 2, a tail part of the plug, 3, a groove, 4, a cylindrical cavity, 5, an external thread, 6 and a conical cavity.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
Any process or method descriptions in flow charts or otherwise described herein may be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps of the process, and the scope of the preferred embodiments of the present invention includes other implementations in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the embodiments of the present invention.
As shown in fig. 1 and 2, the utility model provides a piercing plug for seamless steel tube production, which comprises a plug head part 1 and a plug tail part 2, wherein the plug head part 1 is a conical vertex angle with a gradually shrinking outer diameter from right to left, and the conical surface of the plug head part 1 is provided with a sawtooth-shaped groove 3; the right end of the ejector tail part 2 is provided with an inwards concave cylindrical cavity 4, the inner wall of the cylindrical cavity 4 is provided with an external thread 5, the ejector head part 1 is provided with a conical cavity 6, and the conical cavity 6 is communicated with the cylindrical cavity 4.
The angle of the conical vertex angle of the plug head part 1 is 45-60 degrees, and when the angle of the conical vertex angle is 45-60 degrees, the service life and the production efficiency are most balanced.
The groove 3 is of a spiral structure, and compared with a stepped structure, the sawtooth-shaped groove 3 of the spiral structure has longer service life and reduces production cost.
In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention.
