What spare parts are needed for the motor automatic rotor spot welding test machine and how to set up the guarantee stock?
The spare parts of the fully automatic rotor spot welding test machine usually include wearing parts, electrical components and other related accessories, etc. The following is the specific introduction and the method of setting up the protection stock:
I. Spare parts list
1、Wearable parts
Spot welding electrode: directly contact with the workpiece in the process of spot welding, easy to wear, need to be replaced regularly to ensure the quality of spot welding.
Electrode cap: installed at the end of the spot welding electrode, is directly involved in the spot welding parts, wear and tear faster, need to be replaced regularly.
Guide rail slider: used in the equipment to realize the precise movement of the components, after a long time of use may be due to wear and tear and affect the accuracy of the movement.
Seals: used to prevent liquid leakage in the equipment, such as the hydraulic system or cooling system in the seal, aging or damaged need to be replaced in a timely manner.
2、Electrical components
Fuse: in the circuit overload or short circuit, the fuse will fuse to protect the equipment and personnel security, is a common perishable electrical components.
Relay: used to control the circuit on and off, frequent use may lead to contact wear or coil failure, need to have a certain number of relays.
Sensors: such as pressure sensors, displacement sensors, etc., used to monitor the operating status and parameters of the equipment, may be due to aging, damage and affect the normal operation of the equipment.
Contactor: mainly used to control the motor and other loads on and off, after a long time of use contacts may appear ablation and other problems, need to be as spare parts.
3、Other accessories
Screws and nuts: during the operation of the equipment, some connection parts of the screws and nuts may be loose or lost, need to prepare different specifications of the screws and nuts.
Wire and cable: wire and cable may need to be replaced due to aging, wear and tear or accidental damage, a certain number of spares should be prepared according to the specifications of the wire and cable used in the equipment.
Cooling fan: the cooling fan in the equipment is used to dissipate heat to ensure that the equipment operates within the normal temperature range, fan failure may lead to overheating of the equipment, you need to prepare spares.
Second, to protect the inventory setup method
1, analyze historical data: review the past operating records of the equipment, statistics on the replacement frequency and use of spare parts. For example, if in the past year, a certain type of spot welding electrodes replaced an average of 5 per month, then the electrode can be initially set to protect the stock slightly higher than the average monthly use.
2. Consider the operating condition of the equipment: If the equipment has a long operating time and high frequency of use, or if the production task requires high reliability of the equipment, then the guaranteed inventory should be increased appropriately. On the contrary, if the frequency of use of equipment is low, you can appropriately reduce the guaranteed inventory.
3, the supply cycle factors: for the procurement cycle of longer spare parts, guarantee inventory should be set higher to prevent stock-outs in the procurement cycle. For example, some kind of imported sensors procurement cycle for 3 months, then the guarantee stock should be able to meet the demand for the use of these 3 months.
4, cost factors: consider the cost of spare parts, for the higher cost of spare parts, in order to ensure the normal operation of the equipment under the premise of guaranteeing that the inventory should not be too high, so as not to take up too much money. Can be negotiated with the supplier to establish an emergency procurement mechanism, etc., in the need to be able to quickly access spare parts.
5, to determine the number of guaranteed stock: a combination of the above factors, to determine the number of guaranteed stock of spare parts. For example, the guaranteed stock of spot welding electrodes can be set to 8 - 10, the guaranteed stock of electrode caps is set to 15 - 20, fuses, relays and other electrical components according to different specifications, each set 5 - 10 guaranteed stock.
The setting of guaranteed stock needs to consider various factors and be adjusted dynamically according to the actual operation of the equipment and production demand to ensure the normal operation of the equipment and avoid excessive backlog of stock.
