What are the daily maintenance contents of the frame Hydraulic Press?

1、 Pre shift inspection of Frame Hydraulic Press (5-10 minutes before startup)

Appearance and Safety

Check the body, columns, rails, and sliders for cracks, deformations, or obvious damage.

Confirm that the safety protection devices (safety doors, light barriers, emergency stop buttons) are intact and effective, without looseness or obstruction.

Clean the workbench, guide rails, and surrounding debris to ensure no interference.

hydraulic system

Check if the hydraulic oil level is within the range of the oil gauge and if the oil color is normal (without emulsification or blackening).

Check for any signs of oil leakage in the hydraulic pipelines, joints, and cylinders, and promptly address any leaks found.

Confirm that the oil temperature is within the allowable range (usually 20-60 ℃), and preheat without load for 5-10 minutes during low temperatures in winter.

lubrication system

Check the lubrication points of the guide rail and slider guide sleeve, confirm that the lubricating grease/oil is sufficient and the oil circuit is unobstructed.

Manually or automatically lubricate once to ensure sufficient lubrication of the motion pair.

Electrical and Control

Check whether the wiring of power supply, gas source, emergency stop, travel switch, etc. is secure and whether there is any damage.

Move the slider with no load to check if the up and down movement is smooth, without any abnormal noise or jamming.

2、 In class monitoring of frame hydraulic press (in operation)

Operating status

Pay attention to the sound of the hydraulic pump, motor, and slider during operation. If any abnormal noise or vibration occurs, stop the machine immediately for inspection.

Monitor the pressure gauge, oil temperature gauge, and pressure curve, and promptly investigate any abnormalities such as large pressure fluctuations or sudden oil temperature increases.

It is strictly prohibited to operate beyond the tonnage, stroke, and speed limits to avoid biased processing.

Working condition record

Record the pressure, frequency, and abnormal situations during the production process to provide a basis for regular maintenance.

If there are problems such as oil leakage, abnormal noise, insufficient pressure, etc., the machine should be stopped and reported. It is forbidden to operate with problems.

3、 Post shift maintenance of frame hydraulic press (after shutdown)

Cleaning and resetting

Turn off the power and gas supply, clean the workbench, mold, and machine surface of iron filings, oil stains, and dust.

Stop the slider at the lower limit or safe position to avoid long-term hovering that may cause aging of the cylinder seal.

Organize hydraulic pipelines to avoid compression and bending.

Simple check

Recheck for oil leakage, loose fasteners, and other issues, mark any problems, and prioritize handling the next day.

Fill in the equipment operation log, indicating the production situation and abnormalities of the day.
