Centrifugal cement pipe machine is the main equipment for forming centrifugal cement products, is the tool for continuous operation. The supporting wheel is the main part of the cement pipe making machine, and it is easy to wear during the forming process. Therefore, people pay more attention to the repair and improvement of its structure.
The wear and tear of the roller will affect the normal operation of the cement pipe die, which will cause the bending deformation of the cement pipe die, which will seriously affect the quality of the products.
Wear of (a) riding wheel
There are two kinds of wheel wear and end wear. There are two kinds of outer wear, one is uniform wear, the outer diameter of the supporting wheel is reduced; the two is uneven wear.
(two) the cause of wear
Uniform wear on wheel friction drive cement pipe die rotation caused by, is a normal phenomenon, uneven wear is uneven and running wheel and supporting wheel running is not normal caused by the wheels holder, such as impact and so on.
Face wear is cement pipe die to produce axial movement caused the, die shifting reasons: centrifuge installation uneven; mold feeding to the undue concentration of at one end; a group or a group of supporting wheel of the horizontal center line and the whole unit supporting wheel in the center line is not vertical, the mold structure caused by itself, such as: tapered pole size end, pressure pipe with Bell and spigot, supporting wheel outside the mold cantilever length etc.; caused by additional mechanisms, such as: prestressed tension device; caused by structure and length of transmission shaft; by the supporting wheel and run the gap size between the wheel due to unequal.
(three) the consequences of wheel wear
Uneven wear of the wheel will cause the mold to beat, which will not only affect the quality of cement products, but also speed up the wear and tear. Mould axial movement will make roller and running wheel flange wear intensifies, increase equipment load, serious may also speed and other accidents.
(four) repair of wheel wear
Repair method is: the roller from the bearing seat in the demolition, the truck bed processing, excircle dimensions must be to wear most serious minimum size as the standard size of metal cutting margin, supporting wheel repair after must comply with relevant supporting the provisions of round of technical standards.
