In the manufacturing process of conical sleeve forgings, due to the complexity of materials and processes, some common problems may occur. These problems can affect the quality of products and process efficiency. This article will introduce some common problems and their causes.
Surface Defects Surface defects include cracks, air bubbles, inclusions, and porosity, which are usually significant quality problems that affect the forging.
Causes: It may be due to incorrect temperature, pressure, speed in production or improper heat treatment of the blank.
Dimensional Deviation The dimensional deviation of the shaft includes diameter deviation, length deviation, and surface roughness deviation after processing.
Causes: The causes of dimensional deviation may be equipment design, debugging, material quality, and temperature and pressure processes in production.
Burrs and Excessive Chamfers Burrs refer to rough edges during metal cutting. Excessive chamfers mean that the surrounding edges are stretched or deformed.
Causes: Improper selection of process schemes or machining processes or improper equipment adjustment may lead to burrs and excessive chamfers.
Poor Corrosion Resistance It cannot withstand corrosion-resistant chemical components and may exhibit passivation patterns such as staining or rusting on the surface of the metal shaft.
Causes: It may be due to overheating, insufficient cooling processes, the type of materials used in the metal shaft, and the processing methods used.
Material Extrusion This refers to material incorrectly flowing and forming extrusion patterns, which usually leads to cracks in specific parts or extreme conditions of the structural elements.
Causes: It is common between equipment maintenance and the gap between component replacements, or due to improper flow control during the process and the instability of metal shaft quality.
In summary, some common problems may occur in the manufacture of conical sleeve forgings. Solving these problems requires correct technical and process methods and strict quality control. By understanding the common causes of these problems, better problem-solving and improvement can be performed to improve product quality and production efficiency.
