High-speed punch press bearings generally punch in main shaft, crankshaft, gear rotating parts, such as punch is the key to ensure the punch stable performance.In order to ensure the high quality of punching machine.Miyoshi high-speed punching machine, punching machine adopt NSK bearing NSK bearings, stable quality, grinding and low sliding bearing loss, long service life.(partial NSK bearings manufacturer also is nominal, mostly some unlicensed manufacturers do, domestic, is not recognized by the Japanese technology licensing and our bearing, have the agent certification, can provide certification) is a precision machine tool spindle bearing spindle bearing, and similar devices to guarantee the working accuracy of precision machine tools and the use of performance has played a decisive role.
But even if high-speed punch press with the highest performance of bearing, the event if the composite bearing stamping production, maintenance, improper use, also can't achieve the desired effect.So, high-speed punching machine operators in the actual use and maintenance of punch bearing is important to pay attention to:
Part 1, to ensure the bearing and the surrounding clean.(to avoid any dust falling into)
2, according to the actual operation rules, careful use.(prevent punch bearing onslaught)
3, high-speed punch press bearings are equipped with special tools, be sure to use a special tool to operate when using bearing.The alternative (banning the use of tools)
4, pay attention to rust and lubrication of the bearing.(be sure to wear gloves when actual bearing maintenance to prevent hand sweat. Pay attention to the corrosive gas)
High-speed punch press bearing for rotary motion in a press machine for a long time, it is important to make full lubrication, to ensure its long-term sensitivity of operation, bearing on the maintenance of the most important supplement for lubricating grease.The basic purpose of lubrication oil supplement:
1, on the surface of the sliding bearing lubrication lubrication (to prevent direct contact with metal)
2, in rolling contact form oil film, so that the ability of load, good wear resistance.(the above two have the effect of the noise of the press at the same time.)
3, with aging of grease and small abrasion powder wash effect.
4, the existence of lubricating grease make the bearing corrosion, dust, good effect of vibration insulation, sound insulation, etc.
But counterproductive when lubricating grease additives such as: bearing overheating and last for a long time in high temperature condition, grease leakage and so on.Embellish is lubricating grease recharge too small, lubricating grease can't cycle until the end of the bearing body interior, cause if insufficient sliding bearing friction between the metal, cause temperature rise of bearing.
5, bearing lubrication oil added time interval, to punch the sign on the daily operation of similar days 24 hours time), which can greatly prolong the service life of bearing, and ensure their normal operation for a long time.
