Aluminum profile extruder parts damage cause & repair


1. Overall fracture

When the part is subjected to external loads such as tension, compression, bending, shearing and twisting, fatigue fracture may occur in the dangerous section, such as breakage of the guide post, breakage of the bolt, and breakage of the root of the gear tooth.


2. Excessive residual deformation

If the stress acting on the part exceeds the yield limit of the material, the part will produce residual deformation, such as bending of the shaft, deformation of the gland, and the like.


3. Surface damage of parts (the main cause of part failure)

The surface damage of the parts is mainly corrosion, wear and contact fatigue. These are the forms of failure that occur gradually with the continuation of working time, such as the wear of the guide rail and the abrasion of the copper sleeve.


4. Destruction of failure caused by normal working conditions

A sliding bearing such as a liquid friction can only work normally if there is a complete lubricating oil film; if these necessary conditions are destroyed, different types of failures will occur, such as bearing overheating, gluing, wear, etc., belt drive The failure of slippage occurred.
