Blister cutting machine often crushed knife die most of the reasons are the following three points:
First, the problem: the accumulation of dust and dust under the set guide block is too much, and the guide can not contact the travel switch when pressing down the press plate, so as to crush the cutter mold;
Solution: Clean up clutter;
Preventive measures: regularly clean the debris next to the machine;
Two, the problem: travel switch fault can not transmit signal.
Solution: replace the new travel switch.
Three, the problem: Blister cutting oil road failure;
Solution: please contact professional maintenance, do not disassemble inspection.
When analyzing and selecting the median function of the directional valve in the hydraulic system of the three-position hydraulic cutting machine, the following points are usually considered:
First, the system pressure.
Two, system unloading.
Commuting stability and accuracy.
Four. Startup stability. When the valve is in the middle position, if a cavity of the hydraulic cylinder is connected with the tank, it is not stable to start because there is not enough oil in the cavity to play a buffer role.
Five, hydraulic cylinder. Horizontal hydraulic cylinder is "floating" state, can use other institutions to move the worktable, adjust its position.
