Description
TECHNICAL FIELD
[0001] The utility model relates to bus detection technical field, concretely is a bus stress analysis with wire end fixing device. BACKGROUND
[0002] As the key consumables in the field of precision machining, the preparation process of diamond wire (diamond cutting wire) directly affects the cutting performance. The core carrier of the diamond wire bus adopts high-strength steel cord as the base material, and forms a micron-level diamond plating layer structure through multi-channel composite processing. In the continuous production process of the bus, the cord line mode is adopted, but the line tension is prone to non-steady-state fluctuations due to process fluctuations. This dynamic tension imbalance not only causes subsequent plating defects, but also may cause wire breakage risk during cutting.
[0003] The existing tension monitoring scheme mainly relies on a contact type mechanical detection device. Its working principle is to form a shear force field through the tensioning wheel and the counter-roller, so that the running bus produces elastic deformation, and the tension value is converted based on Hooke's law. This scheme has inherent defects: the local stress concentration area formed during the detection process will cause plastic deformation of the line body, and long-term operation will cause the bus to relax. Moreover, the contact measurement method is easy to introduce surface damage, which affects the subsequent plating layer bonding strength. This contradiction is particularly prominent in the production of diamond wire for photovoltaic silicon slicing, and non-contact dynamic tension monitoring technology needs to be developed. In view of this, the above problems are studied in depth, and the present case is produced. CONTENT OF THE UTILITY MODEL
