Abstract
The invention relates to a large-diameter high-density molybdenum alloy plug which is a tapered rotor. One end of the rotor is a tip, and the other end of the rotor is a round planar bottom. The tip end to the bottom of the plug is in an arc structure. The plug is provided with a connecting hole and a structural hole inside. The connecting hole is formed between the bottom and the structural hole in the plug. The wall of the connecting hole is provided with a connecting thread. The diameter of the structural hole is smaller than or equal to the diameter of the connecting hole. The plug is provided with a shell layer and an inner connecting layer. The shell layer is fixedly connected with the inner connecting layer to form an overall structure. Compared with the prior art, the large-diameter high-density molybdenum alloy plug in the complex structure has the advantages that the shell is made of molybdenum alloy, the inner connecting layer of the plug is made of common carbon steel, and accordingly production cost and application cost are reduced greatly; the large-diameter high-density molybdenum alloy plug is usable as a large-diameter molybdenum alloy plug and is low in cost and convenient to mount and use.
Description
Technical field
The present invention relates to pierce the top of steel pipe, especially a kind of major diameter high-density molybdenum alloy top head that adopts composite construction.
Background technology
At present, the top is general to be used for piercing the seamless steel pipes such as stainless steel tube, alloy pipe, and the material of top is molybdenum alloy etc. normally.Molybdenum alloy is to add the alloy that other elements form take molybdenum as base, in refractory metal, Mo and Mo alloys has good heat conduction, electric conductivity and the low coefficient of expansion, at high temperature (1100～1650 ℃) have high intensity, compare with tungsten, easily processing, thereby in electron tube, electric light source, metal machining tool (die casting and extrusion die and perforating head) manufacturing sector and aerospace industry, be applied.
Existing molybdenum alloy top head generally is overall structure, when molybdenum alloy top head pierced steel pipe at the heat bundle, usually because friction produces damage, service life was shorter between its surface and the steel pipe, the diameter of top namely needs the top that more renews after less than given size, and production cost and use cost are higher.
Summary of the invention
For the deficiency of above existing molybdenum alloy top head, the purpose of this invention is to provide a kind of use cost and reduce, adopt the major diameter high-density molybdenum alloy top head of composite construction.
The objective of the invention is by realizing by the following technical solutions:
The major diameter high-density molybdenum alloy top head, described top is made as the revolving body of conical structure, and the one end is made as the tip, and the other end is the bottom that is made as circular flat, is made as arc-shaped structure from coming directly towards the tip to bottom, described top; Inside, described top is provided with connecting hole and structure hole, and connecting hole is located between bottom, described top and the structure hole, and the hole wall of connecting hole is provided with connecting thread.
As the preferred technical solution of the present invention, the diameter of described structure hole is less than or equal to the diameter of described connecting hole.
As the preferred technical solution of the present invention, described top is provided with outer shell and interior articulamentum, and outer shell is connected with interior articulamentum and fixes and form overall structure.
As the preferred technical solution of the present invention, described outer shell closely is connected by interference fit with interior articulamentum and forms overall structure.
As the preferred technical solution of the present invention, be bolted and fix between described outer shell and the interior articulamentum.
As the preferred technical solution of the present invention, the diameter of bottom, described top is more than or equal to 100 millimeters, and the height of top is more than or equal to 300 millimeters.
The invention has the beneficial effects as follows: with respect to prior art, the present invention adopts composite construction, and the outer shell of top adopts molybdenum alloy material, and the interior articulamentum of top adopts ordinary carbon steel, thereby the cost of top is reduced greatly.The present invention is applicable to the major diameter high-density molybdenum alloy top head, and cost is lower, and is easy to install.
