2、Operating standard and process
Start-up and shutdown process: Train the staff on the correct start-up steps, such as checking whether there are any foreign objects in the appearance of the equipment, whether the power connection is normal, whether the initial position of the switches is correct, turning on the power supply, control system, cooling system (if any) in order, and observing whether the self-test status is normal after the equipment is started up; when shutting down the equipment, stop the equipment from running, turn off the relevant work units (such as the magnetizing power supply), and turn off the control system and the main power supply, as well as turn off the power after shutting down. When shutting down the machine, first stop the operation of the equipment, shut down the related working unit (such as magnetizing power supply), then shut down the control system and the general power supply, and organize and clean the equipment after shutting down.
Main points of daily operation: Teach employees how to correctly place bearings, magnets or motor parts to be processed, including the specific loading position and attitude requirements; how to set the pressure parameters of the bearing pressure, the intensity and time parameters of magnetization on the control panel, as well as the basis and scope of parameter adjustments; how to start single-step operation or automatic cyclic operation, and how to observe the working status during the operation of the equipment (e.g., whether the movement of each part is smooth, whether there is any abnormality, and whether there is no abnormality). Whether the movement is smooth, whether there is any abnormal sound or vibration), and timely handling of simple abnormalities (such as clearing off the slight jamming).
3、Protection knowledge and protection measures
Introduction of protective devices: Introduce the various protective devices equipped on the equipment to the staff, such as the location and function of the emergency brake button (in what kind of emergency to use and press the equipment response), the interlocking mechanism of the protective door (protective door open when the equipment automatically stops or can not be started), photoelectric sensors constitute the protection of the light curtain (its detection range and action after the trigger), etc., to ensure that the staff are familiar with and can use these protective facilities correctly. Ensure that employees are familiar with and can properly use these protective facilities.
Protective operation guidelines: formulate detailed protective operation specifications, such as strictly prohibit reaching out or body close to moving parts when the equipment is running, prohibit equipment adjustments or maintenance without stopping, must wear personal protective equipment (protective gloves, goggles, etc.) and the correct way to wear, as well as set up around the equipment the meaning of the warning signs and comply with the requirements, etc., and analyze the serious consequences of violating the protective regulations through actual cases, to strengthen the protection of employees. The serious consequences of violating the protection regulations may lead to, and strengthen the employees' awareness of protection.
Emergency handling methods: Train employees on emergency handling procedures in case of equipment failure, fire, electric shock and other emergencies. For example, how to quickly press the emergency brake button and report to the superior in case of abnormal movement caused by equipment failure; how to use fire extinguishers in case of fire (selection of types and operation methods) or evacuate to the protective area; how to cut off the power supply and give simple first aid (such as the basic steps of cardiopulmonary resuscitation) in case of electrocution, etc, so as to improve the ability of the staff to cope with the unexpected dangers.
4、Quality Control Points
Explanation of quality standards: make clear the product quality standards of pressed bearings and magnetized products, such as the pressure accuracy requirements (deviation range) of pressed bearings, the tightness standards of bearing and shaft; the magnetic field strength uniformity requirements of magnetized products, the magnetic stability indicators after magnetization, etc., so as to make the employees clearly understand the quality characteristics of qualified products.
Quality Inspection Methods: Teach employees how to carry out quality self-inspection during the production process, such as using simple gauges (calipers, micrometers, etc.) to measure the dimensional accuracy of the press-fit, using a Gaussmeter to detect the magnetic field strength of the magnetization, and mastering the way of recording and feeding back the quality data; at the same time, introduce the sampling process and standards of the quality control department, as well as the matters that should be coordinated by the employees during sampling process, such as providing the production records, assisting in tracing the production process, etc. and assisting in tracing the production process, etc.
Analysis and solution of quality problems: Train employees to analyze common quality problems, such as the loosening problem caused by insufficient pressure on the pressure bearing, which may be caused by wrong pressure setting, hydraulic or pneumatic system failure, or wear and tear of the press head; insufficient magnetizing strength may be caused by the failure of the magnetizing power supply, aging of the magnetizing head, or improper distance, and so on. For different quality problems, teach employees the corresponding solution measures or reporting process, such as self-adjustment of parameters, replacement of wearing parts or timely notification of maintenance personnel and quality management personnel, etc., to ensure product quality stability.
5、Maintenance knowledge
Daily maintenance tasks: arrange for employees to learn the daily maintenance of equipment work content, such as cleaning the surface of the equipment and the internal dust, debris (including wiping the motor, sensors, control cabinets and other components), check whether the fasteners of the equipment is loose (each connecting bolts, nuts, checking and fastening methods), lubrication of the moving parts of the equipment (to determine the lubrication point, select the appropriate lubricant and lubrication cycle and operating procedures), and Checking electrical wiring for breakage, aging, etc. (appearance check and simple conductivity test), and requiring employees to develop the habit of carrying out maintenance work daily or every shift and recording maintenance logs.
Regular maintenance items: Introduce the regular maintenance plan and items of the equipment, such as replacing wearing parts (replacement cycle and operation of drive belt, brush, seal, etc.) every certain period of time (monthly, quarterly or annually), checking and calibrating sensors (calibration method and tool use of position sensors, pressure sensors, etc.), adjusting the precision parameters of the equipment (e.g., calibration process of the accuracy of pressure of press bearings and the accuracy of the magnetizing strength) , conduct all tests on the electrical system (including insulation resistance test, electrical component performance check, etc.), as well as the performance test and acceptance criteria of the equipment after maintenance, to ensure that employees understand the importance of regular maintenance of the equipment and the specific implementation methods.
Maintenance records and reports: train employees how to fill in the equipment maintenance records, including records of maintenance time, content, found problems and solutions and other detailed information; at the same time, teach employees how to report to the superiors in a timely manner when they find a major equipment failure or abnormalities (report object, report mode and report content requirements), so that the maintenance staff can quickly respond and deal with to ensure the normal operation of equipment and the continuity of production. The maintenance staff can respond quickly and handle the situation to ensure the normal operation of the equipment and the continuity of production.
