The invention discloses a rapid tempering process of a formed steel wire for an automobile seat. The rapid tempering process of the formed steel wire for the automobile seat comprises the following steps that (1), the formed steel wire is fixed to a loosening and clamping assembly, the loosening and clamping assembly comprises two heating copper blocks, and the two heating copper blocks are clamped at the two ends of the formed steel wire; (2), a resistance value of the formed steel wire is calculated, and electric energy required for heating the formed steel wire to a set temperature is calculated by utilizing a resistance heating principle; (3), required voltage and current are provided through a power transformer, a positive electrode and a negative electrode of the power transformer are separately connected to the corresponding heating copper blocks through wires, and an electric loop is formed; and (4), the power transformer is controlled to heat the formed steel wire to a set time, so that the formed steel wire is heated to a set temperature to finish tempering. According to the rapid tempering process, the formed steel wire is subjected to heat treatment by utilizing the principle that the resistance of the formed steel wire generates heat, so that the formed steel wire is heated and tempered within an extremely short time, the treatment time is short, the cost is low, and the production mode of large-batch online continuous production is better met.
Description
technical field [0001] The invention relates to a rapid tempering technology, in particular to a rapid tempering process for forming steel wires for automobile seats. Background technique [0002] Many forming steel wires are involved in the production of car seat parts, some of which require stress relief after forming to reduce the impact of force deformation. The general drawing requirement is 300°C tempering. Conventional tempering furnace tempering needs to be transported in batches for tempering, which takes a long time. For the mass production of auto parts and the subsequent processing of formed steel wires, it is difficult to achieve online continuous production, and it is difficult to achieve single piece flow in the process, increasing logistics transshipment, increased production costs, not suitable for automated production. Contents of the invention [0003] The purpose of the present invention is to provide a rapid tempering process for forming steel wires f...
