In the manufacturing process of Steel Floating Joint Shell, achieving precise dimensional accuracy and good surface quality is the key to meeting higher assembly accuracy and sealing performance requirements.
First of all, the design and manufacture of the mold are crucial. Use high-precision processing equipment to make the mold to ensure that the dimensional error of the mold is controlled within a very small range. For example, using a CNC machining center to mill the mold can achieve micron-level accuracy. The structural design of the mold should also be reasonable, taking into account the shape characteristics and molding process of the shell to ensure uniform material flow during the molding process and avoid local deformation or dimensional deviation.
The selection of processing technology and parameter optimization are important factors affecting dimensional accuracy. For steel shells, common processing methods such as cutting and stamping require strict control of process parameters. In cutting, reasonably select parameters such as tool type, cutting speed, feed rate and cutting depth. Too high a cutting speed may cause the tool to wear too quickly and affect dimensional accuracy; while too low a feed rate will reduce processing efficiency and increase production costs. Through multiple tests and data analysis, the best combination of processing parameters is determined to ensure that the dimensional accuracy of the shell meets the requirements.
In the stamping process, control the parameters such as the gap of the stamping die, stamping pressure and stamping speed. The appropriate die gap can ensure that the material is uniformly deformed during the stamping process, reduce the rebound phenomenon, and thus improve the dimensional accuracy. At the same time, the use of advanced stamping equipment, such as servo presses, can accurately control the various parameters in the stamping process to achieve high-precision stamping.
The control of surface quality should not be ignored. During the processing, use appropriate cutting fluids or lubricants to reduce friction and heat generation during the processing process and prevent surface burns and scratches. For parts with high surface roughness requirements, subsequent processing such as grinding and polishing can be carried out. When grinding, select the appropriate grinding wheel grain size and grinding process parameters to obtain the required surface roughness. Polishing can further improve the surface finish, reduce surface microscopic defects, and improve sealing performance.
In addition, the quality inspection link is an important guarantee to ensure dimensional accuracy and surface quality. Advanced measuring equipment, such as three-dimensional coordinate measuring machines and optical profilometers, are used to comprehensively test the size and surface quality of the shell. Strict quality control standards and testing processes are established to adjust or rework unqualified products in a timely manner to ensure that each Steel Floating Joint Shell can meet the high requirements for assembly accuracy and sealing performance. Through the above measures, the dimensional accuracy and surface quality of the Steel Floating Joint Shell can be effectively and accurately controlled, providing reliable performance guarantee for it in various high-end application scenarios.
