Abstract
Novel perforate and come directly towards, including nasal part, perforation portion, roll off portion and afterbody, the nasal part be the nipple shape, perforation portion and the streamlined transition of roll off portion, the afterbody be provided with the chamfer, the inside cooling hole that is equipped with in perforation top, the cooling hole includes toper section, first rectangle section, round platform section, second rectangle section, circular arc section and third rectangle section. The utility model discloses cooling hole bonding strength index requires there is a gradient that scales up with cold going, and the wall thickness that waits of having broken through the top tradition design of perforating cools off even mode for the top inefficacy of perforating delays, the life extension.
Description
Technical field
This utility model relate to a kind of tubulation instrument, has particularly related to a kind of New Type Piercing Plug.
Background technology
Perforating head is one of key tool of seamless steel tube production, and the quality of its quality and the length in service life will be straight
Connect quality and the cost affecting perforating machine production hollow billet.At present, quality and the service life of domestic perforating head used are the lowest
In international advanced index, become in China's steel pipe's production one of good and length in service life the perforating head of development quality is important
Problem.
During rolling seamless steel pipe or high temperature alloy pipes, first with coming directly towards on perforating machine being heated to regulation
The round steel billet of temperature carries out drilling/rolling and becomes seamless steel pipe, contacts owing to top is gapless with the steel billet after heating, locates all the time
High temperature, high capacity occasion under, be highly susceptible to abrasion and corrode, particularly its structure design irrational situation
Under, wear and tear faster.
Summary of the invention
The deficiency existed for prior art, the purpose of this utility model is that and provides New Type Piercing Plug, not only
Wear-resisting, high temperature resistant, and service life is long.
To achieve these goals, the technical solution adopted in the utility model is such that New Type Piercing Plug,
Including nose, perforated portion, roll off portion and afterbody, described nose is disk shape, described perforated portion and rolling
Rolling portion's flowing transition, described afterbody is provided with chamfering, is provided with cooling endoporus, in described cooling inside described perforating head
Hole includes conical section, the first rectangular section, round platform section, the second rectangular section, arc section and the 3rd rectangular section.
This utility model cooling endoporus bond strength index and cold going require an incremental gradient, breach perforation top
The wall thickness that waits of head traditional design cools down uniform pattern so that perforating head lost efficacy and delays, and service life extends.
True form after this utility model mammiform nose and abrasion is close, and nose uniform wall thickness, cooling condition
Good, the beneficially formation of oxide-film, described mammiform nose thickness is 12.5mm, and mammiform nose is blocked up, and cooling effect is poor,
Nose easily melts scaling loss, and mammiform nose is the thinnest, insufficient strength, and nose easily extrudes to be scrapped, and described nose is provided with two sprays
Water hole, so can make nose sufficiently cool.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
1 nose 2 perforated portion 3 roll off portion 4 afterbody 5 hole for water spraying 6 conical section 7 first rectangular section 8 round platform section 9 in figure
Second rectangular section 10 arc section 11 the 3rd rectangular section.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings, but not as to restriction of the present utility model:
New Type Piercing Plug, including nose 1, perforated portion 2, roll off portion 3 and afterbody 4, described nose
1 is disk shape, and described perforated portion 2 and roll off portion 3 flowing transition, described afterbody 4 is provided with chamfering, institute
Being provided with cooling endoporus inside the perforating head stated, described cooling endoporus includes conical section the 6, first rectangular section 7, round platform section 8, second
Rectangular section 9, arc section 10 and the 3rd rectangular section 11.This utility model cooling endoporus bond strength index and cooling requirement have one
Individual incremental gradient, the wall thickness that waits breaching perforating head traditional design cools down uniform pattern so that perforating head lost efficacy and prolongs
Slow, service life extends.
True form after this utility model mammiform nose 1 and abrasion is close, and nose 1 uniform wall thickness cools down bar
Part is good, beneficially the formation of oxide-film, and described nose 1 thickness is 12.5mm, and mammiform nose is blocked up, and cooling effect is poor, nose
Easily melting scaling loss, mammiform nose is the thinnest, insufficient strength, and nose easily extrudes to be scrapped, and as preferably, described nose 1 is provided with
Two hole for water sprayings 5, so can make nose 1 sufficiently cool.
Above-described embodiment of the present utility model, only clearly demonstrates the citing that this utility model is done, but is not used to
Limiting protection domain of the present utility model, the technical scheme of all equivalents falls within category of the present utility model, this utility model
Scope of patent protection should be limited by every claim.
