First, the quality of Hangwo chain starts from the material, and we use superior raw materials:
A) Superior alloy steel plates from large steel mills such as Xingcheng Special Steel and Huaigang Iron and Steel are adopted;
B) Superior alloy round steel produced by large special steel mills such as Xining Special Steel;
c) Superior alloy steel pipe (the billet of which must be supplied by a large steel mill).
2. Hangwo Chain has a number of advanced modern equipment:
a) Adopt the international advanced imported high-power laser cutting machine - for the processing of large chain plates and complex contour chain plates, high grade accuracy;
B) Domestic advanced CNC machining center - using German power head, Japanese CNC tool, for high-precision boring processing of chain plate after heat treatment, hole accuracy up to ±0.05mm, pitch tolerance within ±0.10mm;
C) High-efficiency and high-precision circular saw-used for blanking of roller sleeve pins, the end face of blanking is very flat, the parallelism and dimensional accuracy are high, the efficiency is high, and the blanking automation is realized;
D) domestic advanced inclined rail lathe (auxiliary manipulator) - for the rough and finishing of roller sleeve pins, high processing efficiency, the use of Japanese CNC tools, the machining accuracy is guaranteed;
E) Domestic advanced assembly riveting equipment - used for the whole chain assembly, pin shaft riveting, to reach the industry processing level;
F) 5000KN large CNC chain plate leveling machine - the equipment adopts German Aku technology, which is mainly used for leveling after heat treatment of chain plate, and the thickness can be used to level 22mm thick plates, and the leveling accuracy deviation can reach 0.30mm, which solves the phenomenon of uneven twisting after chain assembly;
G) Efficient automatic welding - our company adopts the automatic welding of FU chain hook in China, after years of use and transformation, workers get started quickly, do not need to go through complex training, can be used on the job, and achieve high quality and high efficiency of welding;
Third, the heat treatment of Hangwo chain adopts the method of commissioned processing, the processing enterprise is a professional heat treatment enterprise, with an investment of more than 200 million heat treatment equipment and testing equipment, with advanced heat treatment equipment, including the United States Ipsen controllable atmosphere multi-functional furnace, vacuum quenching furnace, large-scale multi-functional continuous mesh belt furnace, CNC intermediate frequency quenching machine, etc., as well as including metallographic analysis, material analysis, tensile testing and other equipment. At present, it is a heat treatment product of SKF, Wolf and other internationally renowned manufacturers, and a strong guarantee for the superior product quality of Hangwo;
Fourth, Hangwo chain itself also has a number of testing equipment, the common ones are image measuring instrument, metallographic analysis, Rockwell hardness tester, Brinell hardness tester, Leeb hardness tester, non-destructive testing equipment, etc. Quality inspectors strictly implement the inspection procedures, in the process of the first piece, sampling, batch inspection, strict quality control, never allow unqualified products to leave the factory.
Fifth, Hangwo in the production process, is also constantly improving, in the production process for many years, through the introduction of advanced equipment, such as the use of high-precision laser cutting and cutting, machining center processing, instead of the previous stamping process, improve the accuracy of the product, but also increase the service life of the product; In addition, there is the transformation of automated production, first of all, to solve the problem of the current labor shortage, for the adjustment of the current industrial structure, to reduce the labor intensity of workers, the same
