What spare parts are needed for brushless motor manual six-station internal winding machine and how to set up the guarantee stock?
The spare parts of brushless motor manual six-station internal winding machine usually include wearing parts, electrical components and other general parts, etc. The following are the specific contents and how to set up the guarantee stock:
I. Spare parts list
1、Mechanical wearing parts
Winding mold: During the winding process, the mold will be worn out due to frequent use, which affects the winding accuracy and needs to be replaced regularly.
Belt: Used for power transmission, aging, wear and tear, stretching and other problems will occur after long time use, resulting in a decline in transmission efficiency, need to prepare different specifications of the belt.
Gears: gears in the transmission process may appear tooth wear, broken teeth, etc., according to the equipment used in the gear specifications to prepare spare parts.
Guide rail slider: when the equipment is running, the guide rail slider will be constantly friction, prone to wear, jamming and other problems, need to prepare the appropriate type of guide rail slider.
2、Electrical components
Contactor: to control the circuit on and off, frequent action may lead to contact erosion, should be prepared for different rated current contactor.
Relay: used for signal conversion and control, there may be coil burning, contact sticking and other faults, need to prepare common specifications of the relay.
Fuse: It plays a protective role when overload or short circuit occurs in the circuit, and the fuse of the fuse may be blown, so it is necessary to prepare a variety of fuse with different melting currents.
Motor: Brushless motors may have problems such as short-circuiting of windings and damage of bearings, so it is necessary to prepare motors of the same type as spare parts.
3、Other general parts
Screws and nuts: screws and nuts of various specifications are used to fix mechanical parts and electrical components to prevent loosening.
Wires and cables: different specifications and models of wires and cables, used for electrical connection, in order to prepare for line damage in time for replacement.
Sensors: such as counting sensors, position sensors, etc., there may be inaccurate signals, damage, etc., you need to prepare the appropriate sensor spare parts.
Second, to protect the inventory setup method
1、Based on historical data method
Collect data: Collect the use data of each spare part of the winding machine in the past period of time (at least 12 months), including the replacement time, the number of replacements.
Analyze the data: Calculate the average monthly usage of each spare part, the great monthly usage and the frequency of usage and other indicators.
Determine the guaranteed stock: Generally speaking, the guaranteed stock can be set at 1.5 times to 2 times of the average monthly usage. For spare parts with high usage frequency and long procurement cycle, the guarantee stock can be increased appropriately.
2、Based on the equipment operating conditions method
Equipment evaluation: Regularly inspect and evaluate all the winding machines to understand the wear and tear of each part of the equipment and its operation status.
Forecast demand: Based on the operating condition of the equipment, forecast the spare parts and quantity that may need to be replaced in the future. For the parts with serious wear and close to the service life, the guarantee stock should be increased appropriately.
3、Based on the procurement cycle method
Determine the procurement cycle: Understand the procurement cycle of each spare part, including the supplier's production cycle, transportation time, etc..
Set security stock: security stock should be able to meet the procurement cycle of equipment maintenance needs. Generally, the guaranteed stock can be set up according to 1.2 times to 1.5 times of the procurement cycle. For example, the procurement cycle of a spare part is 1 month, and the average monthly usage is 5, then the guaranteed stock can be set to 6 to 8.
When setting the actual guaranteed stock, it is also necessary to consider the enterprise's financial situation, storage space and other factors to ensure the normal operation of the equipment under the premise of reasonable control of inventory costs.
