Induction Motor Rotor Winding Forming Machine Repair

Recently, the company's large-scale motor R off-line induction motor rotor winding has accounted for nearly 40% of the output in the past three months, and due to customer customization needs, it has shown the dual production pressure of "many varieties and specifications". This situation puts forward strict requirements for the continuous operation capacity of the workshop's core equipment, the five-in-one parallel headgear forming machine, and the equipment is seriously aging and worn. Under high-intensity production loads, the connecting rod breaks and the drive shaft is stuck. Frequent failures directly lead to the shutdown of the R rotor motor, and the production schedule is facing serious challenges.

Equipment is the basis of workshop production, and the normal operation of equipment is essential to the production efficiency and product quality of the workshop. Therefore, in order to quickly reverse the passive situation, the Manufacturing department activated the emergency response mechanism as soon as possible, and established a special emergency repair team with the backbone of equipment, machining, and riveting and welding as the core. Clarify the emergency repair strategy of "surveying and mapping priority, sequence processing, and collaborative assembly".Among them, the equipment team took the lead in carrying out the heavy task of technical research: for irregular parts such as connecting rods and drive shafts (no original drawings are archived), the equipment engineers took the initiative to map and map one by one to ensure accurate data.After the drawings were delivered, the riveting and welding and machining teams quickly entered a "war-time state", forming an efficient and connected process chain: the riveting and welding branch gave priority to the cutting process, and the two welders selected 45# steel materials to accurately cut the blank parts of the connecting rod according to the requirements of the drawings, and at the same time pretreated the welding parts of the drive shaft to ensure the flatness of the welding surface of induction motor rotor winding. Error control; Subsequently, the machining factory continued to promote refined processing, and the lathe process first roughed and semi-finished the shaft holes of the connecting rods to ensure that the aperture and dimensional tolerances met the H7 standard; the grinder process then precision ground the outer circular surface of the drive shaft , So that the surface roughness reaches Ra0.8µm; finally, the machining center performs CNC milling on the special-shaped groove structure of the connecting rod to achieve precise forming of complex contours.The various processes are closely connected, and overtime is worked to complete the processing of key parts of the headgear.

The five-in-one parallel headgear forming machine has completed the replacement and commissioning of the core components. During the start-up trial production, all parameters reached the normal operating standards, the production capacity was restored to the pre-failure level, and the operation was stable and stable, effectively guaranteeing the production progress of the large motor R off-line induction motor rotor winding. In this emergency repair work, everyone worked together and cooperated together, demonstrating the spirit of unity and cooperation. The equipment team of the manufacturing department demonstrated the professionalism of "excellent technology and overcoming difficulties", and the riveting and welding and machining teams embodied the spirit of "rapid response and precise execution". The spirit of collaboration.With the core goal of "ensuring production and rushing progress", they used practical actions to interpret the entrepreneurial spirit of "responsibility" and "collaborative combat" under the challenge of no drawings, tight time, and high accuracy requirements, and set an excellent example of post achievement for all employees.

Here, I would like to highly affirm the hard work of the equipment team of the manufacturing department, the machining factory, and the riveting and welding branch of all the personnel involved in the emergency repair, and commend them! I hope that all departments will follow their example, strengthen their sense of collaboration and enhance their professional capabilities in follow-up work, take the initiative to take responsibility and cooperate efficiently in the face of production problems, and jointly build a strong production guarantee line for the company's high-quality development!
