Abstract
The invention discloses a high-strength seamless steel pipe piecing plug which comprises a plug body. A plug is disposed at one end of the plug body. The inside of the plug is of a hollow structure. A support center is disposed in the middle inside the plug. A plurality of support rods are disposed between the side wall of the plug and the support center and used for enhancing the pressure resistance of the inside of the plug. A composite high-temperature alloy layer is disposed on the outer layer of the plug body. The high-strength seamless steel pipe piecing plug has the advantages that the inside of the plug is of the hollow structure with the support rods, materials are saved, weight is reduced, the stress can be shared by the support rods, and maximum pressure resistance can be achieved; the composite high-temperature alloy layer disposed outside the plug body can increase the pressure and crack resistance of the plug body.
Description
Technical field
The present invention relates to seamless steel pipe production, particularly a kind of efficient cracking resistance resistance to compression piercing plug for seamless steel tubes.
Background technology
Seamless steel pipe is all to be formed being heated to the pipe stock drilling/rolling of uniform temperature by piercing plug for seamless steel tubes conventionally, piercing plug for seamless steel tubes is in the process of perforation, piercing plug for seamless steel tubes need to bear the larger pressure from pipe blank, and this is easy to cause piercing plug for seamless steel tubes and Central Cracking.
Patent 201220410101.2 discloses a kind of piercing plug for seamless steel tubes, its cracking resistance resistance to compression measure is for being provided with combined high temperature alloy-layer on the middle part periphery at top body, yet this patent only discloses the Crack Resistance at perforating head middle part, in fact, in perforation procedure, top head is introduced into steel duct, must first bear pressure, therefore comes directly towards head easily impaired.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to improve a kind of efficient cracking resistance resistance to compression piercing plug for seamless steel tubes, not only can make perforating head middle part cracking resistance, can also make to come directly towards head resistance to compression cracking resistance.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of high-strength seamless steel pipe perforating head, comprise top body, body one end, top is provided with top, end, top is provided with alloy head, it is characterized in that, inside, described top is hollow structure, and in top, middle part is provided with centre of support, between top sidewall and centre of support, be provided with several support bars, for strengthening coming directly towards inner pressure resistant ability.
A high-strength seamless steel pipe perforating head, is characterized in that, described support bar quantity is 4-15 root.
A high-strength seamless steel pipe perforating head, is characterized in that, described support bar quantity is 9.
A high-strength seamless steel pipe perforating head, is characterized in that, described centre of support and support bar material are combined high temperature alloy.
A high-strength seamless steel pipe perforating head, is characterized in that, this volume surrounding of described top is provided with combined high temperature alloy-layer.
Usefulness of the present invention is: 1. inside, top is made as to the hollow-core construction with support bar, not only saves material, weight reduction, also because support bar can decompose suffered power, can farthest bring into play resistance to compression effect on the contrary; 2. this volume surrounding of top is provided with combined high temperature alloy-layer, can increase the resistance to compression anti-crack ability of top body.
Accompanying drawing explanation
Fig. 1 is high-strength seamless steel pipe perforating head schematic diagram of the present invention.
The implication of Reference numeral in figure: 1. come directly towards, 2. top body, 3. alloy head, 4. centre of support, 5. support bar, 6. combined high temperature alloy-layer.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
In conjunction with Fig. 1, a kind of high-strength seamless steel pipe perforating head, comprise top body 2, body 2 one end, top are provided with top 1, come directly towards 1 end and be provided with alloy head 3, 1 inside, described top is hollow structure, come directly towards 1 interior middle part and be provided with centre of support 4, come directly towards and between 1 sidewall and centre of support 4, be provided with 9 support bars 5, come directly towards 1 inside and be made as the hollow-core construction with support bar 5, not only save material, weight reduction, also because support bar 5 can decompose suffered power, can farthest bring into play resistance to compression effect on the contrary, described centre of support 4 is combined high temperature alloy with support bar 5 materials, described top body 2 skins are provided with combined high temperature alloy-layer 6.
A high-strength seamless steel pipe perforating head, except said structure, its difference is, described support bar 5 numbers are 4.
A high-strength seamless steel pipe perforating head, except said structure, its difference is, described support bar 5 numbers are 15.
High-strength seamless steel pipe perforating head of the present invention has put into production and has tried out, respond well.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
