Abstract
A cooling lubricant device with a removable mandrel bar relates to metal rolling. In order to avoid the abrasion problem on the mandrel bar at high temperature and pressure during the seamless steel tube rolling process, the method of single mandrel bar cooling and single lubricating systems is generally applied, which degrades the quality of the tube inner wall for the low productivity effect and poor lubrication effect. The mandrel of the invention is a hollow rotary body when in operation and inputs the lubricant and cooling water simultaneously into the mandrel bar which is rotating via the insulation and closure structure between a holder and a connector body, with the lubricant ejecting from the front head of the mandrel to lubricate the tube inner wall while the cooling water, so as to form a circuit within the mandrel bar to cool down the temperature for the mandrel bar. When in the rolling process, not only the mandrel bar can be cooled but also the tube inner wall can be lubricated, which can prolong the service life of the mandrel bar and improve the quality of tube inner wall. Besides, the dosage of the lubricant consumption is decreased, cost is saved and environmental pollution is reduced.
Description
Technical field
The present invention 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 objective of the invention is to overcome existing technical disadvantages, a kind of cooling and lubricating device of mobile mandril is provided, 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 present invention is achieved through the following technical solutions its goal of the invention.
A kind of cooling and lubricating device of mobile mandril, its removable hollow plug one end other end that is threaded with seal nipple is threaded with hollow push rod, hollow push rod is connected with hollow ejector rob trolley provided axle by shaft coupling, be provided with bearing I between described hollow ejector rob trolley provided axle and the ejector rob trolley provided body, hollow ejector rob trolley provided axle is connected with rotating shaft, rotating shaft is installed in the counter flange that is connected with ejector rob trolley provided body by bearing I I, in stock and the fittings body, the lubricant joint is housed on the stock and is communicated with lubricant passageway in the rotating shaft, warter connection is housed on the fittings body and is communicated with cooling-water duct in the rotating shaft, lubricant passageway is communicated with lubricant tube and along hollow ejector rob trolley provided axle, hollow plug stretches into the inner chamber of top guide, top guide is provided with spray orifice, cooling-water duct is communicated with cooling water pipe and along hollow ejector rob trolley provided axle, hollow push rod enters the front end inner chamber of plug, plug inner chamber and hollow push rod, hollow ejector rob trolley provided axle, the inner chamber of counter flange is communicated with, and counter flange is provided with drainage joint.
Be provided with sealing between described stock and fittings body and the rotating shaft.
The present invention compared with prior art because plug is a hollow rotary body, by isolation between stock and the fittings body and hermetically-sealed construction, imports 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.
