Requirements for safe operation of cold wire rolling mills
Working characteristics and requirements under different working systems of cold profile wire rolling mills: The working systems of strip rolling mills generally have two types: irreversible and reversible, so let’s talk about these two in detail.
Under the irreversible working system, the working characteristics and requirements of the precision wire rolling mill are mainly:
(1) On the rolling stock, the length of the rolling stock is long and the gap is short. In the wire rolling load, the load should be uniform.
(2) In terms of speed requirements, the adjustment speed range should be wide, the bite speed should be low, but the rolling speed should be high. Under the reversible working system, the working characteristics and requirements of the cold rolling mill are different, and it can be controlled by a computer.
Safety requirements for cold flat wire rolling mill machine operators
1 The operator has passed the training and examination and is certified to work
Safety operation procedures, mechanical maintenance inspection and shift system are perfect
3 The load-bearing operating site is flat and the foundation is solid
The weight of the counterweight of the machine is sufficient, the lifting stability is reliable, and it meets the technical requirements
5 The braking device is reliable and effective
6 Speakers, bells and other audio signal devices are complete, clear and loud
There are obvious color codes and light signals for components such as hoisting, walking, slewing, and luffing.
Technical indicators such as larger lifting weight and amplitude are marked in obvious positions
9 Lifting parts are equipped with limit switches and elevation limit switches, which are sensitive and reliable.
10 rotations, the luffing part is equipped with rotation and amplitude limit switches, which are sensitive and reliable.
The travel part of the track is traveled with a limiter at the terminal, and the rail clamp is sensitive and reliable.
12 The interlocking device of each limit switch is flexible and effective, and it is not allowed to dismantle and close at will
13 The operating room has a good line of sight
More than half of the edge of the escalator platform walkway has a railing, and the lower part has a 0.15m baffle
15 metal frame, equipment shell, reliable grounding of track, resistance less than 4Ω
16 The power supply line cable is well insulated
17 Check the running lights, the voltage of the audio device is less than 50v
18 The steel wire rope is not damaged and meets the technical requirements
