In mid-December of 2011, the new type of complex tool developed by Hanjiang Tools, the taper worm gear hob, was used by a reducer user. The taper helix accuracy and processing efficiency all met the user's requirements. This is a result of Hanjiang Tool's directing to the needs of the user's process, and it is a further fruit of R&D. It marks a new breakthrough in the development of high-precision and complex tool development and reducer markets.
The taper worm gear drive has just started in domestic applications. The most common worm gear transmissions are cylindrical worm drives and ring-shaped worm gear drives. Compared with the cylindrical worm, the worm and worm drive smooth, large load capacity, high efficiency, compact structure when the drive is relatively large. The taper worm gear hob is a complex tool for machining taper worm gears. The tooth surface is Archimedes spiral surface, both the outer bottom diameter and the chip flutes are tapered, and the spiral taper feed line is formed and coated in research and development. Material and control and many other key issues.
During the development process, Hanjiang Tools started with the study of user processes, adopted CAD technology, played the advantages of advanced equipment, solved spiral thread taper feed line formation, coating materials and control, and successfully developed this difficulty. Big new product. Particularly worth mentioning is that in coating technology, Hanjiang Tools cooperates with the world-famous tool coating company Balzers Coating Technology Co., Ltd. in the new model of partners and suppliers. On the one hand, Balzers borrows the Han River. The site and process validation resources of the tool are used for coating research. On the other hand, Hanjiang Tools provides special tool coating services, which makes Hanjiang Tools’ tool coating technology at the advanced level in the world.
The complex tool that embodies and supports the complex surface integration technology of the group company is well-known in the domestic market. In recent years, Hanjiang Tools has succeeded in developing the largest insert hob, solid carbide hob, heavy-duty double-cut hob, 50-inch super-arc milling cutter, high-precision blade root cutter, cylindrical shape cutter, and large specifications. Broachers, dry-cut hobs, pinion cutters, oversized worm gear hobs, etc., whose technical level is synchronized with the international market, and is monopolized in the domestic market; with hobbing tools, cutting tools, broaching tools, and high-precision blade root milling cutters The representative of the complex gear cutting tools and high-precision cutting tools, the overall level ahead of the domestic industry, the market share of nearly 45%, is the country's first tool brand; as the first batch of tool industry to undertake major national science and technology major projects, national science and technology support plan The research company of the project, Hanjiang Tools has undertaken a total of 17 major cutting-edge topics such as tool products and three numerical control processing equipment. It has also participated in the research and development of two major national science and technology projects and three research and development projects in Shanxi Province. The research and development products have achieved 15 provincial-level scientific and technological achievements, highlighting the high-end and independent innovation capabilities of Hanjiang Tools.
