Precision Hydraulic Press For CNC Reverse Stretching Process Of Kitchen Utensils

Standard operating steps for precision hydraulic press for CNC reverse stretching machining of kitchen utensils:
1. Preparation before homework
Equipment inspection: Confirm that the appearance of the hydraulic press is undamaged, all components are securely connected, and the electrical circuits are not damaged.
Mold inspection: Check whether the installation of the reverse stretching mold is stable, whether there is damage or deformation, and ensure that the mold is clean.
Material preparation: Prepare the raw materials for kitchen utensils to be processed, check their size, quality, and surface condition.
Numerical Control System Setting: According to the machining requirements, input the correct process parameters in the numerical control system, such as pressure, stroke, speed, etc.
Safety protection: Ensure that operators wear necessary protective equipment such as gloves, goggles, etc.
2. Startup and preheating
Turn on the main power switch and start the hydraulic press.
Preheat the equipment, usually for 5-10 minutes, to stabilize the oil temperature and other parameters.
3. Loading and positioning
Accurately place the raw materials on the mold and use positioning devices to ensure their positional accuracy.
4. Start processing
After confirming that the parameters are correct in the CNC system, start the reverse stretching machining program.
5. Processing process monitoring
Closely observe the operating status of the hydraulic press, including pressure changes, stroke movement, speed stability, etc.
Pay attention to the deformation of raw materials and promptly detect possible wrinkles, cracks, and other issues.
6. Intermediate inspection (if necessary)
At a specific stage of the processing, pause the equipment and conduct size and shape checks on the semi-finished products to compare with the standards.
7. Processing completed
When the CNC system displays that the machining is completed, the equipment automatically stops running.
8. Unloading and Inspection
Carefully remove the processed kitchen appliance components and conduct a comprehensive quality inspection, including dimensional accuracy, surface quality, shape conformity, etc.
9. Equipment cleaning and maintenance
Clean up residual materials and oil stains on molds and workbenches.
Perform daily maintenance on the equipment, such as adding lubricating oil and checking the hydraulic oil level.
10. Shut down
Turn off the power supply of the CNC system and hydraulic press.
For example, if a sudden drop in pressure is found during the reverse stretching process of processing a stainless steel pot, it may be due to a hydraulic system leak and requires immediate shutdown for inspection; For example, when unloading, if there are scratches on the surface of the component, it may be due to the mold surface not being smooth enough and needs to be repaired before the next processing.
Strictly following the above standardized operation steps and paying attention to details and handling of abnormal situations during the process can help ensure the quality of processing and the normal operation of equipment.
