Abstract
A cooling and lubricating device of a movable core rod relates to the rolling of metal. In order to solve the wearing problem of the core rod under high temperature and pressure in the rolling of a seamless tube, a method of a separate core rod cooling and separate lubricating system is usually adopted, but the method is characterized by low production efficiency and poor lubricating effect, thereby lowering the wall quality of the tube. When in work, the core rod is a hollow rotating body. Through a separating and sealing structure between a stock and a fittings body, lubricant and cooling water are simultaneously input to the internal part of the core rod in a rotating state, wherein the lubricant is injected out from the front end of the core rod so as to lubricate the internal surface of the tube, and the cooling water forms a circuit in the core rod so as to reduce the temperature of the core rod. In the rolling process, the core rod can not only be cooled, but also can the internal surface of the tube be lubricated simultaneously, thereby not only prolonging the service life of the core rod, but also improving the quality of the internal surface of the tube. Simultaneously, the dosage of the lubricant is decreased, the cost is lowered, and the environment pollution is reduced.
Description
Technical field
The utility model relates to the rolling of metal, lubricated and cooling device in the time of particularly a kind of hot seamless tube milling train mobile mandril.
Background technology
During the hot seamless tube material is rolling, usually adopt long plug or short mandrel rolling, owing to plug bears high temperature and high pressure when rolling in tubing dual adverse circumstances, the plug that has also will to produce a relative velocity poor with tubing according to technological requirement.Therefore, the wearing and tearing of plug and under the effect of HTHP, consumption is very big, causes production cost very high.In order to address the above problem, generally adopt the method for independent plug cooling and independent lubricating system.That is: 6～8 of employings are one group hollow or solid mandrel, use in turn in the operation of rolling; Before use to plug appearance spraying lubricant.This method not only production efficiency is low, and easily comes off from plug under the high temperature of lubricant in the operation of rolling and the vibration, has reduced lubricant effect.The manufacturer that has sprays into lubricant in the tubing before tube rolling by hand or simple device, and the deadly defect of this method is that lubricant can not evenly spray in the pipe, not only severe contamination working environment, and wasted lubricant in a large number.For above-mentioned reasons, finally cause being reduced by tube rolling material inwall quality.
Summary of the invention
The purpose of this utility model is to overcome existing technical disadvantages, and a kind of cooling and lubricating device of mobile mandril is provided, and plug both can obtain cooling in the operation of rolling, and table can be lubricated again simultaneously in the tubing; Both improve the service life of plug, improved the quality of table in the tubing simultaneously again.Lubricant quantity reduces, and has reduced cost, has reduced environmental pollution.
The utility model is achieved through the following technical solutions its goal of the invention.
A kind of cooling and lubricating device of mobile mandril, comprise hollow plug, hollow push rod, hollow ejector rob trolley provided axle, described hollow plug is threaded with hollow push rod, described hollow push rod is connected with hollow ejector rob trolley provided axle by shaft coupling, it is characterized in that: be provided with bearing I between described hollow ejector rob trolley provided axle and the ejector rob trolley provided body, described hollow ejector rob trolley provided axle is connected with rotating shaft, described rotating shaft is installed in the counter flange that is connected with described ejector rob trolley provided body by bearing I I, in stock and the fittings body, the lubricant joint is housed on the described stock, and be communicated with lubricant passageway in the described rotating shaft, on the described fittings body warter connection is housed, and be communicated with cooling-water duct in the described rotating shaft, described lubricant passageway is communicated with lubricant tube and along described hollow ejector rob trolley provided axle, hollow plug stretches into the inner chamber of top guide, described top guide is provided with spray orifice, described cooling-water duct is communicated with cooling water pipe and along described hollow ejector rob trolley provided axle, hollow push rod enters the front end inner chamber of described hollow plug, plug inner chamber and described hollow push rod, described hollow ejector rob trolley provided axle, the inner chamber of described counter flange is communicated with, and described counter flange is provided with drainage joint.
Be provided with sealing between described stock and described fittings body and the described rotating shaft.
The utility model compared with prior art because plug is a hollow rotary body, by isolation between stock and the fittings body and hermetically-sealed construction, is imported rotating plug inside with lubricant and cooling water simultaneously when work.Lubricant is lubricated to internal surface of pipe in the ejection of plug front end; Cooling water reduces the plug temperature by the inner loop that forms of plug.Plug both can obtain cooling in the operation of rolling, table can be lubricated again simultaneously in the tubing.Not only improve the service life of plug, and improved the quality of table in the tubing again.Simultaneously, lubricant quantity reduces, and has reduced cost, has reduced environmental pollution.
