How to maintain the abrasive belt machine
The belt is an important part of belt machine. How can we maintain the abrasive belt machine?
Only a reasonable selection, proper use of abrasive belt, and belt use in a variety of problems can be solved correctly, displays the superiority and abrasive belt grinding of the best grinding performance, in order to ensure the quality of workpiece.
Before using the belt
Belt storage is important, but the belt before use if it can not be handled properly will seriously affect the performance of it.
Abrasive suspension
The belt before use should be at least 2-5 days of suspension, its purpose is to eliminate curl due to packaging. The packing belt hanging on the belt support 100-200mm diameter pipe or on the special. Pipe length should be greater than belt width or belt to fall off or trumpet; tube should be a level, otherwise easy to damage belt edge. Should conform to the belt hanging belt the environmental temperature and humidity of storage conditions, the simplest way is in a sealed room, with few lamp 40W or 64W lighting to keep dry.
Appearance check
Rear suspension belt before use should be necessary for the appearance of quality inspection, the inspected belt joint whether level off, firm; abrasive belt surface hole, sand group, lack of sand, glue spots, wrinkles; belt edge is neat and cracks, if there is a smaller gap edge, cut (cut into circular arc) does not affect the use.
Due to the abrasive belt grinding of application and research in our country is still in the primary stage, so belt use knowledge presented in the literature, as a belt manufacturer, we at the reception and visit the user, often feel some users of belt storage store and use of knowledge is not very understanding. In order to better services for users, so that the sand belt in use in the best condition to play the superiority of the abrasive belt grinding, now the belt of the storage and use of some knowledge is introduced to everyone.
1 storage belt
Belt storage for belt use is very important, especially the influence on the wide belt. The ideal storage conditions, reasonable storage methods in order to ensure that the use of belt to the best state.
2 temperature and humidity requirements
Belt should not be stored there are larger changes in the temperature and humidity, the ideal temperature for 18-220C; the ideal humidity: 40-65%, the temperature is too high will make the binder aging, reduce the service life of the belt. Synthetic fiber matrix belt (such as polyester cloth belt) is more sensitive to the cold, not cold stored in the warehouse.
The belt will deform the humidity is too high or too low, and the deformation will reduce the bonding strength of glue sand belt. Especially the humidity effect of the belt is quite serious. In addition to water belt, general belt damp after use, are prone to discount, wrinkle phenomenon of the belt machine scrap. In addition, the damp grinding grinding material easy to adhesion in belt surface, reduce the service life of the belt. Effect of high temperature, low humidity on paper backing is relatively large, so that the paper backing is brittle, easy to fracture scrap.
