To operate a multifunctional bending machine, it is necessary to start from five core aspects: safety regulations, equipment debugging, operation procedures, quality control, and maintenance, to ensure efficient, accurate, and safe operation. The specific contents are as follows:
Strictly abide by safety regulations and establish a solid operating bottom line
Personnel protection: Operators must wear anti smashing safety shoes, protective gloves, goggles, and long hair must be tucked into a safety helmet. It is strictly prohibited to wear accessories or loose clothing to prevent entanglement with equipment transmission components.
Equipment inspection: Before starting up, confirm that the emergency stop button is sensitive and effective, the protective devices (such as protective covers and safety gratings) are intact, the power cord is not damaged, and the grounding is reliable; Check that the bending mold has no cracks or deformations, and that the fasteners are not loose.
On site management: It is strictly prohibited to stack debris in the work area, and unrelated personnel are not allowed to approach; When collaborating with multiple people, it is necessary to clarify the division of labor, assign a dedicated person to command, and avoid misoperation.
Carry out equipment debugging and match processing requirements
Mold selection and installation: Select a suitable bending mold based on the material and specifications of the workpiece (such as steel bar diameter, pipe wall thickness). During installation, ensure that the mold is concentric with the spindle and tighten the fastening bolts to prevent mold displacement from causing deformation of the workpiece.
Parameter setting: Set parameters such as bending angle, bending speed, and return speed through the device control panel; For workpieces with curvature requirements, it is necessary to calculate the bending radius in advance, adjust the mold spacing, and perform bending calibration if necessary.
No load trial operation: After debugging is completed, perform no-load operation to check whether the equipment runs smoothly, whether there is no abnormal noise or jamming, and confirm that all actions (such as feeding, bending, and resetting) are accurate and correct.
Follow standard procedures and standardize homework steps
Workpiece preparation: Clean the oil stains, rust, and burrs on the surface of the workpiece to be processed, ensuring that the workpiece specifications meet the requirements of the drawing; For longer workpieces, auxiliary support tools should be prepared to prevent shaking when the workpiece bends.
Loading positioning: Place the workpiece smoothly into the mold, align the positioning reference line, and ensure that the workpiece is tightly attached to the mold; Before starting the equipment, confirm the position of the workpiece again to avoid positioning deviation.
Bending operation: Press the start button, observe the operation status of the equipment and the bending process of the workpiece. If any abnormal deformation or abnormal noise of the workpiece is found, immediately press the emergency stop button to stop the machine for inspection; It is strictly prohibited to touch the workpiece or mold with hands while the equipment is running.
Cutting and re inspection: After the workpiece is bent, wait for the equipment to fully reset before removing the workpiece, measure whether the bending angle and size meet the requirements of the drawing, and adjust the parameters and reprocess the non-conforming products in a timely manner.
Control processing quality and avoid common defects
Prevent workpiece deformation: Control the bending speed to avoid excessive rebound of the workpiece caused by too fast a speed; For materials with poor plasticity, such as high-strength steel bars and thick walled pipes, they can be preheated appropriately before bending.
Reduce dimensional deviation: Regularly calibrate the positioning accuracy and angle sensors of the equipment to ensure that parameter settings are consistent with actual processing; During mass production, a sampling inspection is required for each processed quantity of workpieces to adjust deviations in a timely manner.
Avoiding mold damage: It is strictly prohibited to process beyond specifications (such as bending large-diameter workpieces with small-sized molds) to prevent mold cracking; When processing high-strength workpieces, lubricating oil can be applied to the surface of the mold to reduce wear.
Strengthen maintenance and prolong equipment lifespan
Daily maintenance: After the homework is completed, clean the iron filings and oil stains on the surface of the equipment and molds, wipe them clean, and apply rust proof oil; Check each lubrication point (such as spindle, guide rail), add lubricating oil or grease as needed, and ensure the flexible operation of transmission components.
Regular maintenance: Regularly check the wear and tear of the mold, and replace it in a timely manner when the wear is severe; Check the operating status of the motor, reducer, and hydraulic system, tighten loose connections, and replace aging seals, belts, and other vulnerable parts.
Fault record: Establish an equipment operation ledger to record daily operation parameters, fault phenomena, and handling methods, facilitating subsequent troubleshooting and optimization of operation processes.
