If it is turned by conventional turning, it is easy to roll up the rubber block and scrap it. To this end, we have produced a simple tool body and tool for processing the sealant rubber gasket, as shown below. The car is made of a wooden mandrel, and the big end is larger in diameter than on the chuck. Cut the rubber block to a larger diameter and place it on the end face of the mandrel. Fix it with a pushpin. It should not be wrinkled or stretched too tightly. Then use the diameter of the prepared plastic plate to tighten the top of the tailstock. Turning speed can be selected) 78, to be smooth after the operation to cut, eat the knife can not be too fast, with a small drag plate into the knife is better. The waste composite center drill is sharpened into a turning tool on the grinding wheel, and the cutting edge angle is! 2 After grinding, you must use the oil stone backlight knife face! = (20), to ensure that the cutting edge of the tool is sharp. After the turning tool is sharpened, place the mounting hole of the self-made shank and tighten the turning tool with the screw. Practice has proved that the sealing rubber gasket is processed according to the above method, which saves time and labor, can ensure the accuracy requirement, and the effect is very good. Author unit: Lu'an Bearing Factory Address: Lu'an City, Anhui Province Zip code: Ordinary lathe bed head box shaft sealing structure improvement Chen Jiang In recent years, my unit has purchased several ordinary lathes, and the bed box shaft is common in use. The problem of oil leakage in the sealing device causes the working pressure of the hydraulic oil to drop and the equipment cannot work normally. The analysis and research on the hydraulic seal structure of the shaft shows that the sealing and pressure resistance of the domestic double-sided sealed bearing have to be improved and improved. The oil leakage is caused by the low bearing pressure and the damage of the gasket under the hydraulic pressure. To this end, we have improved the shaft seal structure as shown. A sealing device consisting of parts is added to replace the original double-sided sealed bearing sealing oil pressure function. Double-sided sealed bearings can be replaced by ordinary bearings. This newly designed shaft sealing structure can completely solve the problem of oil leakage caused by low pressure resistance. Most of the same type of equipment in our factory has received good results after adopting this new technology.
