The design of motor progressive dies usually does not focus particularly on fast switching, especially in cases of multiple processes and workstations. Although motor progressive molds have certain operational flexibility and adjustment space compared to traditional molds, there are still certain challenges in achieving rapid switching of molds. The rapid switching of molds usually requires specific design features, such as modular design or a convenient workstation adjustment system, in order to quickly replace molds or adjust the process settings of molds.For motor-driven molds, fast switching mainly depends on the design structure of the mold itself, the adaptability to the workstation, and the complexity of replacing parts. Some motor progressive dies may improve replacement efficiency through replaceable mold plates, workstation adjustment systems, etc., but this still requires some preparation time, especially when multiple processes need to be adjusted. Therefore, although mold switching can be achieved, there are still certain limitations to the rapid switching of motor-driven molds compared to single process molds, especially when frequent adjustments to production content are required.

Motor progressive dies can be used frequently for a long time under certain conditions, but their durability and stability are affected by mold design, material selection, and usage environment. Due to the fact that motor progressive dies are designed for efficient and continuous stamping operations, they are typically able to withstand prolonged high-frequency operations. However, in long-term use, the wear, fatigue, and thermal stress of the mold may gradually affect its performance, especially frequent impacts, friction, and temperature changes during the stamping process may cause wear or other damage to the mold surface.In order to ensure that the motor progressive mold can operate at high frequency for a long time, regular maintenance, lubrication, and inspection are usually required. The design and materials of the mold also need to be able to cope with the pressure and stress in high-speed and high-frequency stamping, avoiding failures caused by excessive wear or fatigue. Therefore, although the motor progressive mold can operate at high frequencies, reasonable maintenance and regular inspections are very important to maintain long-term stability and accuracy.

The design of motor progressive dies usually takes into account certain loads and impact forces, but it is not specifically designed for extreme or sudden impact loads. Due to the need for stable operation of progressive molds under high-speed and high-frequency conditions, the load-bearing capacity and structural strength of each component of the mold have been precisely designed and optimized to ensure that they can cope with the pressure and load during conventional stamping processes. However, sudden impact loads, such as sudden impacts or overloads beyond the design range, may cause damage to the mold, and even lead to mold failure or deformation.The guidance system, stamping components, and material selection of the mold will all affect its ability to withstand sudden impacts. Although molds can withstand certain impact forces, impacts beyond the design range can accelerate wear, cause deformation, and even damage. Therefore, in order to avoid damage caused by sudden impact loads, additional protective measures are usually taken, such as appropriate shock absorption design, reasonable process parameter settings, regular inspections and maintenance, etc., to ensure that the mold will not suffer serious damage in case of emergencies.

The motor progressive die can be adjusted to a certain extent, but the flexibility of this adjustment is usually limited by mold design and processing technology. Due to the fact that the motor progressive die is designed to achieve continuous stamping of multiple processes, the process flow, material input, and stamping action of each workstation of the die are highly precise and optimized. However, in some cases, certain process adjustments can still be made. For example, the production process can be optimized to meet different production needs by adjusting the speed, pressure, number of workstations, stamping depth, or lubrication conditions of the mold.However, if more complex process adjustments are involved, such as replacing the core components of the mold, rearranging the workstation sequence, or changing the processing sequence, more time and effort will be required. This is because the motor progressive die has already taken into account the specific production process during design, and process adjustments may require disassembly, re debugging, or even redesign of the mold. Therefore, although motor progressive molds have certain adjustment capabilities, not every process adjustment can be made at any time, especially for molds that require high precision and efficient production.

Motor progressive dies usually require additional guiding devices. Progressive die is a complex stamping die that can complete multiple processes such as punching, bending, stretching, etc. in the same die. In motor manufacturing, the application of progressive dies is particularly widespread because it can improve production efficiency, ensure consistency and accuracy of parts.The guiding device plays a crucial role in the progressive die. It can ensure the stability and accuracy of the mold during the stamping process, preventing the mold from shifting or deforming when subjected to force. This is crucial for ensuring the quality and performance of the motor, as even small deviations can lead to unstable motor operation or malfunctions.In addition, the guiding device can also extend the service life of the mold. During the stamping process, the mold is subjected to significant impact and friction forces, and the guiding device can disperse these forces, reducing the degree of mold wear.

1. Error leads to uneven stacking of iron cores, reducing motor efficiencyThe automotive micromotor progressive die is responsible for stamping laminated iron cores. If the concentricity error of the mold exceeds 0.01mm, it will cause misalignment or air gaps during the lamination of silicon steel sheets. These micro defects will significantly increase the eddy current loss and hysteresis loss of the iron core, leading to an increase in heat generation and a decrease in energy efficiency during motor operation. 2. Dynamic imbalance exacerbates bearing wear and shortens motor lifeThe iron core produced by the automotive micromotor progressive die is the core load-bearing structure of the rotor. When the concentricity error exceeds 0.01mm, centrifugal force imbalance will occur during rotor rotation, causing the bearing to bear additional radial loads. Under long-term operation, this dynamic imbalance will accelerate bearing wear, increase motor noise and vibration. 3. Air gap magnetic field distortion affects control accuracyIn scenarios such as electronic power steering (EPS) or automatic headlight adjustment, the motor needs to adjust torque or angle in real-time based on the signal. If the error of the progressive die of the automotive micro motor leads to uneven distribution of the magnetic field in the iron core, local distortion of the air gap magnetic density will occur. This distortion may interfere with the signal acquisition of Hall sensors, causing misjudgment by the control unit and ultimately affecting the accuracy of steering force or lighting angle. 4. Error amplification under high-speed stamping threatens batch consistencyThe automotive micromotor progressive die is continuously stamped at a speed of 400 times per minute, and small errors can accumulate and amplify during high-speed production.

1. Reduce the frequency of die replacementThe life of the fan motor progressive die reaches 20 billion punches, far exceeding the durability of ordinary dies. This means that the frequency of die replacement is greatly reduced during the production of fan motors for industrial cooling systems. For example, ordinary dies may need to be frequently shut down for repair or replacement, while high-life dies can operate stably for a long time, directly reducing the production line downtime and replacement costs caused by die failure. 2. Improve production efficiency and qualityThe die can punch at a speed of up to 300 times/minute and supports self-riveting process. High-efficiency production can shorten the manufacturing cycle, while the self-riveting design simplifies the subsequent motor winding and installation steps, reduces manual intervention and potential assembly errors, and thus reduces the risk of cooling system failure caused by part quality problems. In addition, the stable die structure can also reduce product defects (such as heat sink deformation), indirectly improving the reliability of the cooling system. 3. Reduce maintenance complexityThe progressive die adopts a simple structural design for easy maintenance. For example, the self-cooling design of the die and the optimized bearing part (such as metallization and high-reliability ball bearings) can suppress temperature rise and reduce grease consumption and wear. This design makes daily maintenance easier, without the need to frequently disassemble or replace complex parts, saving maintenance hours and spare parts costs. 4. Extend the overall life of the equipmentThe high life of the mold is directly related to its optimized thermal management. For example, it is mentioned that the motor temperature can be reduced by 30K through heat dissipation design (such as thick heat sinks, thermal interface materials), thereby reducing the fatigue loss of bearings and windings. If the fan motor of the industrial cooling system uses components produced by such molds, its own life will also be extended due to temperature control optimization, further reducing the maintenance frequency. 5. Support preventive maintenance strategyCombined with the above-mentioned cooling fan monitoring technology, the components produced by high-life molds can work with intelligent systems (such as CNC speed monitoring function) to warn of potential failures in advance. This preventive maintenance mode is more economical than passive maintenance and can avoid losses caused by sudden downtime.

1. High-precision manufacturing and material selection Washing machine motor progressive die adopts micron-level processing accuracy (step accuracy of 3μm, block accuracy of 1μm), and uses high-strength materials such as cemented carbide to ensure that the parts fit tightly and reduce deviation and wear during stamping. For example, Gree mold has improved the accuracy to 0.001 mm through innovative processing technology, while balancing the blanking gap and reducing problems such as chipping. 2. Structural decomposition and stress dispersion design Complex parts are decomposed into multiple simple processes (such as blanking, flanging, bending), and segmented punching is used to disperse stress and avoid local overload. At the same time, empty spaces are set to avoid too small wall thickness, optimize the overall stress state of the mold, and improve strength. Ningbo Hongda's mold realizes process decomposition through automatic lamination, twisting groove and other functions to ensure stability at high speed. 3. Optimization of guide and unloading system The unloading plate also serves as a guide plate to ensure accurate positioning of the material during high-speed stamping and reduce vibration and offset. Gree optimizes the mold assembly process through CAE simulation analysis, improves the fluctuation problem of the feeding belt, and improves the feeding stability. 4. Automatic detection and electronic monitoring device The mold is equipped with electronic monitoring devices such as misfeeding detection and double material thickness detection to monitor the material position and status in real time to prevent mold damage due to feeding errors or material abnormalities. For example, Ningbo Hongda's molds are automatically monitored through solenoid valves and sensors. 5. Lubrication and maintenance design High-speed punch presses use forced lubrication systems (such as butter lubrication) to reduce wear on joints and maintain long-term operating accuracy. It is pointed out that punching of more than 300 times/minute requires a high-precision punch press with forced lubrication to avoid reduced accuracy and mold damage. 6. Feeding system and dynamic balancing technology Dynamic balancing technology is used to reduce vibration, and combined with feeding step optimization (such as the feeding design of the three-row compressor core mold), to ensure smooth material delivery at high speed. Gree has improved feeding stability to 380 times/minute through structural innovation. 7. Intelligent simulation and process optimization CAE simulation is used to analyze the speed strength and stress state of the mold and optimize the structural design. For example, Gree improved the problems of mold size fluctuation and insufficient assembly precision through simulation and achieved stable production of 360 times/minute. 8. Long life and reliability design The mold life is more than 200 million times, and the service life is extended by segmented punching, high-quality materials and surface treatment (such as three-proof process). Ningbo Hongda's mold has a single grinding life of 1.8 million punches and a total life of 200 million times.

Refrigerator motor progressive die is a die used to manufacture refrigerator motors. Its working principle is based on progressive die technology. Progressive die is a metal stamping process that gradually completes the forming and processing of parts by passing metal strip (such as steel plate or copper strip) from one station to another, and finally forms a complete finished product. Working principle of progressive die: 1. Material input and transfer: The metal strip enters the die from the feed end and passes through a series of arranged stations, each station performing different operations such as punching, bending, drawing, etc. Each time the stamping is performed, the material moves forward a certain distance, thereby gradually completing the forming of the part. 2. Operation process:In the early stations, positioning and preliminary processing, such as punching or cutting, are usually performed to ensure that the material is properly aligned in the subsequent stations.As the material passes through each station, the forming of the part is gradually completed. For example, some stations may be used to bend the outer shell of the motor, while other stations are used to process internal components.The last station is usually a cutting station, which separates the finished parts from the strip. 3. Automation and efficiency: Progressive dies are often used in conjunction with automatic feeding systems to achieve continuous production. This process is suitable for mass production because manual intervention and material waste can be significantly reduced. 4. Mold design and optimization: In order to improve production efficiency and part quality, mold design needs to consider the fluidity of the material and the accuracy of the mold. For example, some molds may contain thickness control devices to ensure that the thickness of the motor core is uniform. In addition, the design of the mold also needs to consider fault detection mechanisms to avoid production interruptions caused by improper material feeding.
