The invention discloses a perforation top of a seamless steel pipe. The perforation top of the seamless steel pipe consists of a nozzle, a rectifying block, a heating tank and a top body; a cavity is formed in the top body; the rectifying block is mounted at the front end of the cavity; the heating tank is formed between the rectifying block and the inner wall of the cavity of the top body; the nozzle is arranged at the front end of the top body; and the heating tank is communicated with the nozzle. The perforation top of the seamless steel pipe has the following advantages: the problem of high-temperature deformation of the top end of a traditional perforation top is solved; the problem of low heat exchange effect of the inner cavity of the top caused by incapability of quick circulating heat exchange due to generation of a steam barrier area in the use process of the inner cavity of the perforation top is solved; and the problem of incapability of synchronously achieving water cooling and lubrication due to only possession of cooling or lubricating effect by the perforation top is solved.
Description
Technical field
The present invention relates to a kind of water-cooled piercing plug for seamless steel tubes.
Background technology
Seamless steel pipe perforation is important procedure in seamless steel tube production, and used tool is exactly piercing plug for seamless steel tubes, and the service behaviour of top how direct relation the height of seamless steel pipe perforation effect and production cost.Therefore people did not stop at all times to the innovation of piercing plug for seamless steel tubes, improvement, and carry out in two the innovation of piercing plug for seamless steel tubes, improvement, one improves top material, and dual-purpose water-cooling pattern improves the mechanical performance during work of top.Innovation, the improvement of current piercing plug for seamless steel tubes are carried out around top material substantially, this is because people improve top material have certain progress, but the red hardness of material has the limit, it is that geometric progression rises that red hardness gets over high cost, and this point is especially embodied on the seamless perforation process of high-alloy steel.Test, practice also show to come directly towards the improvement of Water Cooling Technology, innovation than coming directly towards few many of material.
Because water-cooled top exists vapour locking district when operation and under being positioned at water-cooled top nose, make the heat of top nose increase temperature rapidly and sharply raise and cause top operational failure.When seamless steel pipe perforation process, the reason overwhelming majority of top operational failure is that top nose high temperature loses shape.Disclosed in patent CN203196990U, CN204503759U, water-cooled comes directly towards to have and offers water spray aperture in nose rear flank, top, reduce vapour locking district to a certain extent, because tube wall waste during perforation is close to water-cooled top outer wall under High Pressure, therefore few gasified water can only be had to take away with the displacement of waste tube wall, moreover water-cooled top inner chamber does not change, vapour locking region there is not change substantially, and therefore heat exchange action is too little, and losing shape to top nose high temperature does not affect substantially.The disclosed top of patent US20100089111, US20120210761 is non-water-cooled top, it offers aperture in nose rear flank, top, in order that lubricant flows out from aperture, but because tube wall waste during perforation is close to top outer wall under High Pressure, few lubricant therefore can only be had to take out of with the displacement of tube wall; The causus lubricant produced when perforation is very little to cooling of plug effect.The disclosed top of CN204544969 is also non-water-cooled top, it offers aperture at top nose, in order that lubricant slowly flows out from aperture, because set aperture is just to Mannesmann hole, lubricant must can not make Mannesmann's hole temperature drop intensity liter from aperture, otherwise perforation process failure, so equally very little to cooling of plug effect for the causus lubricant produced during perforation.
Summary of the invention
The object of the invention is to solve existing product, and 1, perforating head top high temperature loses the problem of shape; 2, in use there is vapour locking district in perforating head inner chamber, cannot form cycling hot fast and exchange, and causes coming directly towards the little problem of inner chamber heat exchange action; 3, perforating head only has independent cooling or lubricant effect, cannot accomplish the problem simultaneously with water-cooled and lubrication.
The present invention is directed to the deficiency of existing product, and provide a kind of rational in infrastructure, practical, safe and reliable, effectively prevent top height warm deformation, play a kind of piercing plug for seamless steel tubes of cooling and self-lubricating function fast.
A kind of piercing plug for seamless steel tubes of the present invention, described piercing plug for seamless steel tubes is made up of nozzle, rectifying block, heating tank, top body, the inside of described top body is provided with cavity, the front end of described cavity is provided with rectifying block, heating tank is provided with between described rectifying block and top body cavity inner wall, the front end of described top body is provided with nozzle, and described heating tank and nozzle communicate.
Further, the sidewall of described rectifying block is provided with heating tank.
Further, described heating tank is arranged in the body cavity sidewalls of top.
Further, the quantity of described heating tank is 3-10.
Further, the rear end surface of described rectifying block is provided with collector ring.
Further, described collector ring is front end hemisphere, and rear end arranges coniform horn mouth.
Further, the cavity inner wall of described top body is provided with helicla flute.
The present invention's beneficial effect is compared to the prior art:
1, rectifying block is installed in the cavity front end coming directly towards body, and rectifying block improves the intensity of the front end of top body, prevents top body from use deforming.
2, the front end of cavity is cylindrical, and rear end is that cone shape is conducive to disperseing the stressed of top body, prevents stressed concentrating, improves service life.
3, the front end coming directly towards body arranges nozzle, and nozzle and heating tank communicate, and makes the inner chamber of top body form cool cycles, accelerates the cooling effect of top body, and prevent the inner chamber coming directly towards body from forming vapour locking district, the head temperature of top body is too high, causes losing efficacy.
4, the rear end of rectifying block arranges collector ring, it is inner that boundling shape pressure cooling water enters top intracoelomic cavity, impact on the collector ring of the rear end surface of rectifying block, collector ring makes cooling water rectification disperse and turns to 180 °, after cooling water 180 ° turns to, along the helicla flute of top body cavity inner wall, helicla flute makes cooling water be rotation status, thus reduces the turbulent condition of cooling water, and the state of nonturbulent flow is conducive to the resistance reducing fluid, and then accelerate the speed of heat exchange, top body is cooled fast.
5, cooling water enters heating tank from this process that nozzle flows out, heat exchange is carried out in the front end of top body, cooling water becomes gaseous state from liquid state in this process simultaneously, cracking is produced under high temperature action, gas after cracking, under the High Pressure of the inner chamber of top body, is discharged by nozzle; React with Mannesmann hole inwall after entering Mannesmann hole after cooling water cracking and generate high-temperature lubricant Fe3O4, there is while cooling effect the effect of high temperature lubricating, avoid the problem occurring steel bonding.
