Description
Technical field
The utility model relates to a kind of perforated member of rolling seamless steel pipe, refers more particularly to a kind of novel top.
Background technology
Piercing mandrel plug is one of important mould in seamless steel tube production.In perforation procedure, top surface because of be subject to high temperature, high pressure effect and easily wear and tear, the problem such as melting loss and steel bonding, shortens service life thus, and the inner surface of steel pipe is worsened.
Summary of the invention
The purpose of this utility model is the technical problem solving above-mentioned existence.
The utility model is achieved in that a kind of novel top, comprise top body, top body interior is provided with inner chamber, it is characterized in that: described top body is provided with head and afterbody, is disposed with impact head, circular arc workbench, circular arc chamfering, taper seat from head to afterbody; Described impact head periphery is provided with oxide-film, and impact head and circular arc workbench junction are tiltedly installed with a cooling water hole A, and circular arc workbench left part is provided with a cooling water hole B; Described inner chamber is provided with cylindrical hole C, conical bore, cylindrical hole B, circular hole from the inside to the outside, cylindrical hole A.
The novel top of one described in the utility model, is characterized in that: described cooling water hole A, cooling water hole B all communicate with inner chamber.
The novel top of one described in the utility model, is characterized in that: described cooling water hole A and cooling water hole B is disposed on the same plane.
The novel top of one described in the utility model, is characterized in that: described oxide-film is set to circular arc.
The novel top of one described in the utility model, is characterized in that: the diameter of described cylindrical hole A is greater than the diameter of cylindrical hole C.
The utility model is reasonable in design, manufacturing process is simple, substantially increases the service life of top, reduces maintenance, replacement cost, propagation and employment enhances impact head case hardness and anti-wear performance and high-temperature behavior, so will have good social benefit timely simultaneously.
