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.

Improve mold hardness and wear resistanceHeat treatment can significantly improve the hardness and wear resistance of mold steel through quenching, tempering and other processes. This is especially important for progressive dies, because progressive die for automotive new energy motor needs to withstand large punching force and friction during use. If the die hardness is insufficient, wear and deformation will easily occur, thus affecting the accuracy of the die. and service life. Through heat treatment, the surface hardness and wear resistance of the mold are improved, which can better resist wear and deformation during the stamping process and ensure the long-term stability and accuracy of the mold.Optimize mold organization structureHeat treatment can change the microstructure of mold steel, such as refining the grains, changing the phase composition, etc. These changes help optimize the mold's performance, increasing its strength and toughness. For progressive dies, the optimized organizational structure means better fatigue resistance and longer service life. At the same time, refining the grains can also improve the corrosion resistance and oxidation resistance of the mold, further extending the service life of the mold.Eliminate internal stress and improve stabilityZhejiang Ruixin Mold Technology Co., Ltd. has advanced manufacturing equipment and quality control equipment. It has rich manufacturing experience and technical strength in new energy motor core progressive molds, which can ensure high precision and high quality of molds.

Progressive Lamination Die is a die technology widely used in precision machining. It is mainly used to produce laminated sheets in the core components of motors, transformers and generators. These laminated sheets are usually made of silicon steel or other magnetic materials. After continuous stamping by multiple stations of the die, they are formed into laminated sheets with precise dimensions and complex shapes, which are used to improve the electromagnetic performance and energy efficiency of the equipment. Working principle of progressive lamination dieThe core features of progressive lamination die are "progressive" and "lamination". During the processing, the material (usually metal strip) is driven by the press and passes through multiple stations of the die to gradually complete the processes of punching, trimming, folding, forming and lamination. This method can achieve efficient and high-precision production, especially for the manufacture of large quantities of parts. Through the cooperation of automated equipment, the die can also complete the welding or bonding between the laminated sheets to form a stable component structure. Main application areasMotor manufacturingProgressive lamination die is widely used in motor manufacturing, especially in the rotor and stator lamination processing of asynchronous motors and permanent magnet synchronous motors. It can produce silicon steel sheets with high precision and low loss, improving the efficiency and operating stability of the motor. Transformer manufacturingThe core components of the transformer are usually composed of multiple laminates. The progressive lamination mold can produce laminations with complex shapes and consistent sizes to meet the strict requirements of the transformer for magnetic flux distribution and energy loss during the power transmission process. Power generation equipmentIn wind power generation, hydropower generation and other new energy fields, the rotor and stator of the generator need to use high-performance laminates. The high-efficiency processing method of the progressive lamination mold can meet the industry's demand for large quantities of high-quality parts. Automotive electrification fieldWith the rapid development of new energy vehicles, progressive lamination molds are increasingly used in electric vehicle drive motors. The high-precision laminations produced by it can improve motor efficiency and extend vehicle range. Advantages and prospectsThe outstanding advantages of progressive lamination molds are their high precision, high efficiency and low material waste. Compared with traditional molds, its multi-station stamping design not only shortens the production cycle, but also significantly reduces production costs. With the development of industrial automation and intelligence, progressive lamination molds are evolving towards a more flexible and efficient direction, and are gradually becoming one of the indispensable technologies in the field of high-end equipment manufacturing.

Pump motor progressive dies are essential tools in the manufacturing of pump motor components. These dies are designed to perform multiple stamping steps in a single operation, offering significant improvements in production efficiency, precision, and cost-effectiveness compared to traditional stamping processes. This article explores the production efficiency of pump motor progressive dies and highlights the key advantages they offer over conventional stamping methods. I. Production Efficiency of Pump Motor Progressive Dies Pump motor progressive dies operate by gradually forming components through a series of sequential stamping steps. These dies are particularly suited for high-precision, high-volume production. Several factors contribute to the increased production efficiency of progressive dies: Multiple Stamping Steps, Reduced Tool Change Time A key feature of progressive dies is their ability to perform multiple stamping operations in one cycle. As a result, components are gradually shaped through successive processes within the same die, reducing the need for frequent tool changes. In contrast, traditional stamping processes require a tool change after each operation, resulting in more downtime. Progressive dies significantly minimize tool change times, boosting overall production efficiency. Continuous Production, Enhanced Process Flow Progressive dies ensure a continuous production process where components are progressively formed without interruption. Unlike traditional stamping methods, where each cycle produces a single part and often requires reloading and re-positioning, progressive dies allow for a smoother, uninterrupted workflow. This continuity of production helps maintain consistent throughput and improves manufacturing efficiency. Precision Control, Reduced Scrap and Rework Progressive dies are designed with precise control over each stamping step, ensuring that every component meets stringent quality standards. By managing the tolerance and alignment at each stage of the stamping process, progressive dies significantly reduce the likelihood of errors or defects. This precision minimizes the need for rework, lowers the scrap rate, and ensures that material is used more efficiently. Automated Process, Less Human Intervention Progressive die systems are often integrated with automated feeding, stamping, and ejecting mechanisms, which reduce the need for manual intervention. This automation not only improves production speed but also reduces the potential for human error, contributing to greater consistency and accuracy in the final components. As a result, manufacturers can achieve higher productivity and reduced labor costs. II. Advantages Over Traditional Stamping Processes When compared to traditional single-step stamping, pump motor progressive dies offer several distinct advantages, particularly in terms of precision, speed, and cost-efficiency. Higher Component Precision and Consistency In traditional stamping processes, there is often variability in the precision of each individual part due to tool wear or setup misalignment. In contrast, progressive dies maintain a high degree of precision throughout all stages of the stamping process. Each stamping step is closely controlled, ensuring that the final components are consistent in size and meet tight tolerances. For pump motor components, such as rotors and stators, this level of precision is critical to ensuring optimal motor performance. Faster Production Speed Traditional stamping methods may offer high-speed operations, but the need to change tools after each cycle can result in significant downtime, especially for complex parts. In contrast, progressive dies can produce multiple parts in a single cycle, reducing the need for frequent tool changes. This results in a faster overall production speed. For high-volume production runs of pump motor components, progressive dies can significantly increase output, making them ideal for meeting large-scale production demands. Reduced Tool Maintenance and Replacement Costs Traditional stamping dies often require frequent maintenance and replacement due to wear and tear from repeated use. Progressive dies, on the other hand, are typically designed to be more robust, with a gradual, evenly distributed load during the stamping process. This reduces the frequency of tool replacement and extends the overall lifespan of the die. Consequently, manufacturers can lower maintenance costs and minimize downtime. Improved Scrap Management One of the challenges in traditional stamping is the high volume of scrap produced, especially when forming complex or irregularly shaped components. Progressive dies are more efficient in material utilization, as they are designed to maximize the use of each piece of material and minimize waste. The design of the die allows for better control of scrap, resulting in lower material costs and reduced environmental impact. Enhanced Adaptability to Different Production Requirements Progressive dies are highly versatile and can be easily adjusted to accommodate different component designs and specifications. This adaptability is especially valuable in industries where designs frequently change or new models are introduced. Traditional stamping processes often require entirely new tooling for each change in component design, making them less flexible. Progressive dies can quickly adapt to new production requirements, allowing manufacturers to stay responsive to changing market demands. Higher Automation, Lower Labor Costs Progressive die systems often feature automated material handling, part transfer, and ejection systems, which significantly reduce the need for manual labor. This not only speeds up the production process but also reduces labor costs. Additionally, automated systems improve workplace safety by minimizing the risk of operator injuries, which can occur in traditional stamping environments where workers are more directly involved in handling parts.
