In the field of modern mechanical manufacturing, the performance of heat treatment equipment directly affects the quality and service life of parts. The valve seat induction hardening machine tool launched by Tianjiao Precision Machinery has become an ideal choice for quenching heat treatment of engine valves and various mechanical parts with its advanced technology and stable performance.
The valve seat induction hardening machine tool is a special equipment developed by Tianjiao Precision Machinery for the processing of core engine components. With its continuously upgraded technical concept and adapted to the latest valve processing requirements, it can not only accurately complete the quenching of the engine valve head, but also can be widely used in the quenching heat treatment of various mechanical parts such as gears, bearings, shaft parts, cylinder liners, etc., providing solid guarantee for the production of parts in the automobile, motorcycle, truck and other industries.
The machine tool has strong flexibility in processing range, and can process workpieces with valve stem diameter of 4.5~13mm, head diameter of 17-65mm, and total length of 70-220mm (the technical parameter table subdivided into stem diameter 5-10mm, head diameter 20-50mm, total length 70-150mm). Applicable materials include domestic materials such as 21-4N, 4Cr10Si2Mo, and imported materials SUH3 and SUH35. The hardness of the material before processing must be between 25~45HRc to meet diverse processing needs.
High efficiency and energy saving are the outstanding highlights of the equipment. Its constant power output design speeds up the melting speed, with significant energy-saving effects, and comprehensive energy-saving optimization makes the production cost lower than coal-fired production. Zero-pressure sweep frequency software startup technology is suitable for frequent startup scenarios to reduce equipment loss. In terms of precision control, the machine tool can accurately control the heating length, speed and temperature, so that the workpiece is heated evenly, greatly reducing oxidation and decarburization, and ensuring the forging quality.
The high degree of automation enables automatic loading and unloading and online production, which is simple to operate and efficient. At the same time, the equipment meets environmental protection requirements, has low pollution, and achieves a balance between efficient production and green environmental protection.
The machine tool adopts HT250 cast iron bed, equipped with TG-80 high-frequency machine to complete the quenching process, with a total power of 85KW, and the overall structure is strong in rigidity and high in stability. The automatic loading and unloading mechanism is designed considerately, and the frame can be flexibly adapted to valves of different sizes, which is easy to adjust. When there are faults such as lack of material or full material, the equipment will immediately alarm and stop the automatic cycle to ensure production safety.
The control system adopts Japan's Mitsubishi system and servo system, with built-in PLC and sufficient spare points reserved, and strong scalability. The operation panel can display the cumulative quantity in real time and support permission settings, which is convenient for production management. It also has dustproof, cooling and dehumidification functions, and cooperates with the feeding stroke controlled by the contactless proximity switch to ensure the stable operation of the equipment in a complex workshop environment.
The technical parameters of the equipment are precisely controllable, the quenching depth can reach 2-5mm, and the hardness of the workpiece after quenching can stably reach more than 50HRc. The equipment operates at a frequency of 20~60KHz, a high-frequency current of 380V, and a water pressure of 0.15~0.3Mpa. The single-piece processing cycle is only about 5 seconds. These parameters work together to ensure the quality stability of each processed workpiece and provide a reliable heat treatment solution for machinery manufacturing companies.
Question 1 (focusing on core advantages): What are the outstanding performances of this machine tool in terms of production efficiency and cost control?
Answer: ① In terms of efficiency, constant power output makes the melting speed faster, the workpiece heating speed is fast and the oxidation and decarburization are less, and the processing cycle is about 5s/piece, which is far superior to traditional equipment; ② In terms of cost, comprehensive energy-saving optimization design reduces energy consumption, the production cost is lower than coal-fired production, and high automation reduces labor costs. Zero-voltage sweep frequency start-up reduces equipment loss and further controls costs.
