The Precision Requirements of the Use of Steel Wire Straightening Machine
The moving parts of the steel wire straightening machine (tool holder, worktable, etc.) move along the guide rails of the bed, pillars, beams and other basic parts. The function of the guide rail is to support and guide the moving parts, that is, to support the moving parts. The performance of the guide rail of the steel wire straightening machine directly affects the machining accuracy, load-bearing capacity and performance of the machine tool. Therefore, the guide rail must meet the following basic requirements:
1. Guidance accuracy of the steel wire straightening machine
This is the straightness accuracy of the moving parts when the steel wire straightening machine of indexing control travels along the guide rail and the mutual position accuracy between the guide rail and the relevant reference plane. The guide rail must have sufficient guiding accuracy whether it is no-load processing or rolling processing. The main factors affecting the accuracy of the guide rail are the structure of the guide rail, the manufacturing accuracy and assembly quality of the guide rail, and the rigidity of the guide rail and the basic parts.
2. Maintain the accuracy of the steel wire straightening machine
This means that the guide rail of the steel wire straightening machine can maintain the guiding accuracy even after long-term use. The wear resistance of the guide rail of the steel wire straightening machine is the decisive factor for maintaining accuracy. This is related to the material of the guide rail and the design structure of the guide wheel. In addition to reducing wear on the surface of the guide rail, it also needs to be automatically corrected and adjusted after wear.
3. The smoothness of low-speed movement of the steel wire straightening machine
When the power element moves on the guide rail at low speed or slight displacement, the movement should be smooth and without creep. This requirement is particularly important for steel wire straightening machines. The friction coefficient of the guide rail of the steel wire straightening machine should be small to reduce the friction resistance. In particular, the coefficient of dynamic friction and the coefficient of static friction should be as close as possible to get good results.
