The pull ball of the processing centre component was damaged:
1. Fragmentation phenomenon: the lifting steel ball and the skeletal snail cone in the main axle of the vertical processing centre with an automatic tightening of the apparatus are frequently damaged。
2. Fault analysis: the inspection revealed a lack of coordination between the main axle operation and that of the mechanical hand draw. This is due to the fact that the limit switch was installed at the tail of the cylinder, although the gas tank piston action was in place and the piston action was not in place, which resulted in the mechanical hand pulling the knife, damaging the puller's steel ball and tightening the screws before the handle was released。
3. Fault management: cleaning of pressurized tanks, replacement of seal rings, filling of pressurized tanks, adjustment of the pressure to 0. 5 ~ 0. 8 mpa and disappearance of the failure after trial。
4. Improvement measures: 1. Periodic inspection and cleaning of gas-heavy booster tanks, monitoring of the operation of the parts of the apparatus that are automatically secured by knives, and timely elimination of malfunctions
2 periodically inspect the adjustment of pressure and hydraulic system pressure and test the hydraulic fluids, such as oxidation, for timely replacement。
The positioning keys of the main axis parts of the processing centre were damaged:
1. Fragmentation: the main axis of the vertical processing centre has a high impact on the exchange of knives and the local transformation of the positional key at the front end of the main axis, which moves the handle。
2. Fault analysis: the sound occurs mainly during the mechanical slashing phase, and the failure was initially determined to be the error of the power main axle at the point of loss and the drift of the slash reference point. The main axle is not allowed to stop because of changes in the parameters of the electrical system of the main axle, weak positioning, or an excess of the main axle direction. First, the location of the installation of the hole component was checked, and it was found that the fixed screw was loose, that the knife handled slot was not aligned to the front end of the main axis at the time of the mechanical stroke, and that the positioning key was broken。
3. The installation of the main axle switch reference point close to the switch was similarly relaxed, resulting in a slight downswing of the switch reference point and a handle inserted into the main cone the cone impacts directly on the fixed cone of the main axis at the time of the hole and produces a noise。
4. Fault management: tightening and ductproofing elements after adjusting their placement. Repositioning the main axle switch point of reference close to the installation of the switch, replacing the position keys at the front end of the main axle, and eliminating the malfunction。
5. The improvement measures include periodic inspections of the clean main axle accelerator and of the main axle skeletal reference point locator, the observation of the state of the handle when inserted into the main axle cone, and the timely elimination of the risk of malfunction。
