Safety operation procedures for precision four-guide column punch

1. Operating procedures for precision four-guide column punch
(1) Before starting, check whether the fasteners are firm, whether there are no obstacles in the running parts and sliding surfaces, and whether the limit devices and safety protection devices are perfect.

(2) Before working, make a test run for 10 minutes in an empty stroke, check whether the buttons, switches, valves, limit devices, etc. are flexible and reliable, confirm that the pressure of the hydraulic system is normal, and the working beam moves flexibly before starting to work.
(3) It is strictly forbidden to use the cylinder over stroke.
(4) If the cylinder piston is found to be vibrating or the oil pump makes a sharp sound, the gas must be discharged.
(5) If the equipment has abnormal phenomena or sounds during work, it should be stopped for inspection.
(6) When working, the pressed workpiece should be placed in the middle of the work table and be concentric with the spindle, and the pad should be placed smoothly.
(7) When the work is finished, the working oil pump should be turned off first, then the control oil pump should be turned off, the power supply should be cut off, the equipment should be cleaned, and the inspection records should be made.

2. Safety operation procedures for precision four-guide column punch
(1) Before starting the machine, check whether the fasteners are reliable, whether there are no obstacles in the running parts and sliding surfaces, and whether the limit devices and safety protection devices are reliable.
(2) It is strictly forbidden to use the oil cylinder over-travel, and it is forbidden to process it when it shakes during pressurization or depressurization.
(3) If the cylinder piston vibrates or the oil pump makes a sharp sound, the gas should be discharged.
(4) It is strictly forbidden to adjust the regulating valve and pressure gauge indiscriminately, and the pressure gauge should be calibrated regularly.
(5) Keep the oil quality of the hydraulic oil of the precision four-guide column punch, and the temperature of the working oil should not exceed 45℃. If there is an abnormality, the machine will be shut down.
