Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. When the production of flat planar spiral spring spiral spring production of the first to be designed specifically Archimedean spiral linear mold; Second, we must consider the winding process and heat treatment processes employed. Rectangular strip annealing before winding the first commercially available, can be hand wound when winding method, lathe winding method and special tools winding method. After the flat spiral spring is made, you can not immediately remove it, you should mold around the spring to the furnace heating, quenching temperature rise, remove the mold and spring combination will place it in a suitable oil quenching. Then the tension spring, and then the assembly is heated to the tempering temperature and for a time and then removed. Made good plane scroll spring coils should transition uniform, does not allow bump phenomenon, the surface should be smooth, side acute chamfering or circular arc. The surface should be flat spiral spring oxidation treatment or other preservative treatment. Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment pressure springs, modern plant and professionals, products sold around the world. With the scroll spring widely used in household appliances, sporting goods, security equipment, clocks and timers, to scroll Clockwork also put forward higher requirements. In order to eliminate the adverse residual stress, improve scroll Clockwork surface stress distribution, beneficial to obtain high stress, in addition to measures taken in the choice of material and heat treatment, but in the manufacture of spring plate spring, often using mechanical strengthening processes, such as Shot processing, extreme pressure (pulling, twisting) treatment. Xufeng hardware products are based on variety of materials and processing status of the mainspring to develop, experience can be summarized in three types I, hardened steel processing, such as carbon spring steel wire, piano wire, oil quenched and tempered Second, the thermoformed and has been annealed material cold coil springs, are required to be quenched. Third, after solution treatment and cold-drawn hardened austenitic stainless steel, precipitation hardened stainless steel, steel and copper nickel wire, steel and copper-nickel alloy material produced by cold forming process spring, after forming the need for age hardening Processing ..
