Embodiment 1
[0070] Taking the LG-220H two-roller periodic seamless steel pipe cold rolling mill with a product specification of φ150-220mm as an example, and replacing the roll device with a product specification of φ208*12mm as an example, the calibration of the tooth side meshing clearance of the rolling mechanism is implemented on site. The working steps included in the process are: job preparation, actual measurement of wear equivalent, positioning of working frame (front and rear limit positions), measurement and calculation of tooth side meshing clearance, online adjustment and correction of tooth side meshing clearance, tooth side meshing clearance inspection, etc. The standard clearance of tooth side meshing is 0.15±0.02mm.
[0071] 1) The operation preparation process includes: disclosure of safety technology, implementation of on-site safety precautions, inspection and maintenance operation registration and listing contact, preparation of tooling equipment, etc. → the working fra...
Embodiment 2
[0081] Taking the LG-150H two-roller periodic seamless steel pipe cold rolling mill with a product specification of φ110-150mm as an example, and replacing the roll device with a finished product specification of φ110*7.5mm as an example, the calibration of the tooth side meshing gap of the rolling mechanism is carried out on site. The working steps included in the process are: job preparation, actual measurement of wear equivalent, positioning of working frame (front and rear limit positions), measurement and calculation of tooth side meshing clearance, online adjustment and correction of tooth side meshing clearance, tooth side meshing clearance inspection, etc. The standard clearance of tooth side meshing is 0.12±0.02mm.
[0082] 1) The operation preparation process includes: disclosure of safety technology, implementation of on-site safety precautions, inspection and maintenance operation registration and listing contact, preparation of tooling equipment, etc. → the working...
Embodiment 3
[0092] Taking the LG-110H two-roller periodic seamless steel pipe cold rolling mill with a finished product specification of φ76-110mm as an example, the daily maintenance of the roll device with a specification of φ90*6.5mm is taken as an example, and the calibration of the tooth side meshing gap of the rolling mechanism is carried out on site . The working steps included in the process are: job preparation, actual measurement of wear equivalent, positioning of working frame (front and rear limit positions), measurement and calculation of tooth side meshing clearance, online adjustment and correction of tooth side meshing clearance, tooth side meshing clearance inspection, etc. The standard clearance of tooth side meshing is 0.10±0.02mm.
[0093] 1) The operation preparation process includes: disclosure of safety technology, implementation of on-site safety precautions, inspection and maintenance operation registration and listing contact, preparation of tooling equipment, et...
