2. in process, loosened when clamping occurs in corner oil cylinder, when pressure sensor detects pressure and is less than setting value, micro- electricity
Brain controller can only also carry out early warning, when scene does not have operating personnel, equipment will autostop, when it is live for a long time nobody
During on duty or repairing, the equipment also will always be in dead state, and this will have a strong impact on the processing efficiency of production.
3. at the top of the benchmark boss or inside the positioning chamber of casting tool bottom during out-of-flatness, directly casting has been removed put down again into
Row positioning method, it is difficult to be installed in place casting tool, generally require and rotate casting tool, exchange casting tool inner chamber with
The pairing order of benchmark boss, can carry out accurately installation positioning.So, the labor intensity of operating personnel, production will be increased
Efficiency will also decrease.
