Inspect whether the fixing bolts of the roller shaft bearing housings are securely fastened and whether the lubrication system oil lines are unobstructed. Confirm that the roller shaft adjustment mechanism operates normally, and that the electric or hydraulic adjustment system has no abnormal noise or leaks. Measure the parallelism of the roller shafts to ensure that the error is within the allowable range.

Electrical system safety inspection

Electrical system inspections should begin with the distribution box. Confirm that the main power switch is in good condition with no burn marks and that the emergency stop button is functioning properly. Inspect the control cabinet to ensure that all electrical components are securely installed, wiring is neat and free of exposed wires, and terminal blocks are not loose. Test the equipment's grounding system and measure the grounding resistance to ensure it meets safety standards.

Check that all buttons and knobs on the control panel are functioning normally and that the indicator lights are displaying accurately. Verify that the touchscreen or CNC system is running smoothly, with no screen distortion or touch control malfunctions. Test the interlock function of the safety protection device to ensure that the equipment stops immediately when the protective door is opened. Check that the cable tray is intact, that there is no damage or aging of the cables, and that the cable drag chain moves smoothly without jamming.

Hydraulic and pneumatic system inspection

First, check the oil level in the hydraulic tank, which should be within the specified range. Check that the hydraulic oil is normal in color, with no emulsification or sedimentation of impurities. Start the hydraulic pump and confirm that the pressure gauge reading is stable and that there is no abnormal vibration or noise in the system. Check that there are no leaks in the hydraulic pipe joints and that the hoses are free of cracks or bulges. Test that the hydraulic cylinder operates smoothly, with no crawling or shaking.

Pneumatic system inspection includes confirming that the air filter drains properly and that the pressure relief valve is set correctly. Check that the cylinder moves smoothly and that there are no air leaks. Test that the solenoid valve switches sensitively and that the silencer is working properly. Check that the pneumatic piping is securely fastened and that the quick-release couplings are properly sealed. Confirm that the pneumatic clamp's holding force meets requirements and that the safety pin is functioning properly.

Safety protection device inspection

Check that the mechanical protective cover is securely installed, with no missing or deformed parts. Confirm that the photoelectric protection device is accurate and responsive, and that the equipment stops running when the light beam is blocked. Test the dual-hand operation button function; the equipment must be started by pressing both buttons simultaneously. Check the emergency stop device function; pressing any emergency stop button should immediately cut off the power source.

Ensure that safety warning signs are complete and clear, including warnings for rotating parts, high pressure, operating procedures, etc. Check that the safety area around the equipment is clearly marked and free of clutter. Test the overload protection device to ensure that it functions reliably when overloaded conditions are simulated. Check that the equipment lighting system is working properly and that the operating area is well lit with no shadows.

Workpiece mold safety inspection

Check that the mold is securely installed, the locating pins are in place, and the tightening torque of the bolts meets the requirements. Confirm that the upper and lower molds are accurately aligned and that the gaps are uniform. Check that the mold working surface has no cracks, chipped edges, or other defects. Measure the mold dimensions to ensure that they meet the current processing requirements. Check that the mold lifting device is intact and has no deformation or cracks.

Verify that mold safety precautions are in place and that the guard to prevent workpieces from flying out is installed correctly. Check the storage status of the mold. Unused molds should be stored properly to prevent them from tipping over and injuring people. Confirm that all special tools for mold replacement are complete and in good condition, including lifting equipment, adjustment tools, etc.

Operating environment safety check

Check that the ground around the equipment is flat and dry, free of oil stains or debris. Confirm that safety passages are unobstructed and meet standard width requirements. Check that firefighting equipment is fully equipped, fire extinguishers are within their expiration dates, and fire exits are unblocked. Observe that workshop ventilation is adequate and the welding fume collection system is functioning normally.

Ensure that materials are neatly arranged and that workpieces and finished products are stored in separate areas. Check that lifting equipment is in good condition and that lifting devices are undamaged. Test that the workshop alarm system is functioning properly and that emergency lighting is available. Observe the operation of other equipment to ensure that it does not interfere with the operation of the cone roller.

Personal protection and operating procedures inspection

Inspect the proper wearing of personal protective equipment by operators, including safety helmets, safety goggles, and safety shoes. Confirm that operators are certified and familiar with equipment safety operating procedures. Inspect shift handover records for completeness and ensure that equipment abnormalities are clearly communicated during handover. Observe that operators are in good mental condition and show no signs of fatigue.

Ensure that no unauthorized personnel are present in the operational area and that support staff are positioned safely. Verify that all process documents are complete, including work instructions and safety precautions. Confirm compliance with the first-piece inspection system and ensure that processing parameters are correctly set. Verify that equipment inspection records are complete and that historical issues have been resolved.

Inspection results handling and recording

Issues identified during inspections should be categorized and handled according to their severity. Immediate hazards must be rectified by shutting down the equipment. Major hazards should be reported to the maintenance department for timely handling. General issues can be noted during shift handover. All inspection results should be accurately recorded in the equipment inspection form, including the inspection time, inspector, issues identified, and corrective measures.

Establish a mechanism for tracking inspection issues to ensure that corrective measures are implemented. Important safety hazards must be reinspected and confirmed after rectification. Regularly compile and analyze inspection data, and take fundamental corrective measures for frequently occurring issues. Inspection records should be properly stored and used as a basis for equipment maintenance and safety management.

Safety inspections prior to operating a cone rolling machine are systematic preventive measures that require operators to possess professional knowledge and a rigorous attitude. Through standardized inspection procedures, potential safety hazards can be effectively identified and eliminated, ensuring the safety of personnel and equipment.
