Problems solved by technology

[0005] Therefore, the oil-quenched and tempered spring steel wire of the general process currently on the market has a bottleneck in the coiling speed, and the coiling efficiency cannot be effectively improved. Therefore, how to produce oil-quenched and tempered spring steel wire suitable for high-speed coiling processing of springs is also a problem. Become one of the goals of improving spring production efficiency and improving steel wire quality

Embodiment approach

[0016] see Figure 1-2 A kind of embodiment of the production process of oil-quenched and tempered spring steel wire of the present invention is shown, comprising the following steps: (1) unwinding, check the steel wire steel number, specification, surface quality, and place the steel wire on the pay-off reel (2) heating and heat preservation, the steel wire enters the heating furnace for heating, and the steel wire is austenitized; (3) steam film treatment, the austenitized steel wire passes through the surface treatment device, and the surface treatment device The steam inside reacts with the surface of the steel wire to form a dense oxide film on the surface of the steel wire; (4) Oil quenching, the steel wire after steam film treatment enters the oil quenching furnace for oil quenching to form martensitic steel wire; (5) Tempering , the martensitic steel wire after oil quenching enters the tempering furnace for tempering; (6) non-destructive testing, the surface quality of...

Abstract

The invention discloses a production process for an oil-tempered spring steel wire. The production process includes the steps of (1) paying off, (2) heating and heat preservation, (3) steam skin membrane treatment, (4) oil quenching, (5) tempering, (6) nondestructive inspection and (7) taking up. By the adoption of the production process, lubricity of the steel wire in the winding process is improved, the internal steel wire can be effectively protected, the spring production efficiency is improved, and the steel wire quality is improved.

Description

technical field [0001] The invention relates to a production process of oil-quenched and tempered spring steel wire. Background technique [0002] With the rapid development of my country's machinery manufacturing industry, the demand for domestic suspension springs is increasing year by year. With the continuous improvement of spring production efficiency and the continuous increase of domestic oil quenching and tempering steel wire consumption, the localization quality It has also attracted more and more attention from the spring industry and the metal products industry. [0003] In the process of spring production, it is necessary to wind spring steel wires through different combinations of guide plates, ejector rods and knives to produce springs of different structures. There is inevitably relative friction and wear. At the same time, the most direct and effective way to continuously improve the production efficiency of springs is to increase the winding speed of springs...
