This tube reducer is essential for improving the thermal conductivity and electrical insulation of electric heaters, and is compatible with a variety of heater tubes, including those used in hot runner systems. The HTR-12 is a heater rolling machine characterized by its full gear transmission, ensuring quiet operation and high torque, solving compaction challenges for both large, long tubes and small, short ones.
The HTR-12 tube rolling machine is an MgO compactor that operates via a system of rollers that progressively reduce the tube diameter. Designed for high precision, this machine is crucial in the stage following powder filling, where the goal is to increase the magnesium oxide density within the heating element. The HTR-12 incorporates its own straightening device that ensures the heater coil stretches uniformly inside the element during the rolling process. To adapt to different tube diameters, it is necessary to change the rollers. This roller reduction machine is a technological evolution, equipped with a complete gear reduction system composed of multiple high-precision modular gears. This advanced configuration provides silent transmission and considerable torque, allowing it to effectively handle the compaction of a wide range of tubes, from large and long to small and short. It is, therefore, a versatile tube shrinking machine suitable for any heater tube manufacturer.
The HTR-12 roller rolling machine stands out for its robust and efficient structure, designed to guarantee precision and durability in the MgO compaction process:
Roller Structure: Generally, the machine is presented with 8, 12, 16, or 18 groups of rollers, which work sequentially to gradually reduce the tube diameter. This modular configuration allows for precise adaptation to production needs.
Transmission System: It incorporates a universal shaft drive structure, reinforced with a double cardan drive, ensuring efficient and stable power transmission to all rollers. This complete gear reduction system minimizes noise and maximizes torque.
Integrated Straightening Device: A key component that ensures the uniform stretching of the heater coil inside the element during rolling, preventing deformations and guaranteeing the quality of the heating element.
Die Material: The dies (rollers) are manufactured with high-strength materials such as tungsten alloy or die steel, guaranteeing a long service life and high precision in tube compaction.
Robust Chassis: With a weight of 2500 KG and a volume of 2000x1600x1300 mm, its solid construction minimizes vibrations and contributes to process stability, which is fundamental for the manufacturing of high-quality electric heaters.
The HTR-12 roller rolling machine is a versatile solution for the manufacturing of heating elements across various industries, thanks to its ability to process a wide range of electric heaters:
