Abstract
The utility model provides a piercing plug which comprises a piercing plug body (2); and a composite high-temperature alloy head (1) is arranged at the top of the piercing plug body (2). The plug has the advantages that phenomena such as wearing, collapse deformation and the like in the piercing process are reduced, thereby greatly prolonging the service life of the piercing plug.
Description
Technical field:
The utility model relates to a kind of top that is used for rolling seamless steel pipe.
Background technology:
In seamless steel tube production process, all adopt the top that pipe is bored a hole.Because the working condition the during perforation of top is very abominable, the top needs seamlessly to contact with the pipe of high temperature, also to be subjected to frictional force and extruding force simultaneously from pipe, therefore cause top, the top phenomenons such as distortion of in perforation procedure, very easily wearing and tearing, cave in, thereby shortened the service life that comes directly towards greatly.
The utility model content:
The technical problems to be solved in the utility model is, a kind of high temperature resistant, wear-resisting, not yielding, the top that can improve service life greatly is provided.
Technical solution of the present utility model is that a kind of top with following structure is provided: it comprises the top body; Described top bodies top is provided with combined high temperature alloy head.
After adopting above structure, compared with prior art, the utlity model has following advantage: because the utility model is provided with combined high temperature alloy head at the top of top body, we know, combined high temperature alloy head has good wear resistance and high-temperature stability, therefore, the utility model its top in perforation procedure phenomenons such as distortion that can under the effect of combined high temperature alloy head, be difficult for wearing and tearing, caving in, thus improved greatly service life of the present utility model.
Description of drawings:
Fig. 1 is the main TV structure schematic diagram of the utility model top.
Fig. 2 is the structural representation of the utility model top.
Shown in the figure, 1, combined high temperature alloy head, 2, the top body, 3, inner chamber.
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As depicted in figs. 1 and 2, in this specific embodiment, the utility model top comprises top body 2; Body 2 tops, described top are provided with combined high temperature alloy head 1; Described top body 2 is provided with inner chamber 3; Described inner chamber 3 is provided with screw thread.
