The invention discloses a forming process of a main bolt structure of a fireproof lock. The forming process comprises the following steps that an iron roll material is subjected to blanking and stamping production through a progressive die to be machined into a dead bolt plate with a bent part at one end, and the bent part is used for mounting and fixing one fixing foot of a dead bolt plate swing rod spring; and a dead bolt heat is connected to the dead bolt plate. By means of the main bolt structure of the fireproof lock, the problem that a spring rivet of an original structure is poor in riveting and falls off can be thoroughly and effectively solved, meanwhile, the material consumption of a lock body can be reduced, a riveting procedure is omitted, and therefore the product cost is reduced to a certain degree, the product reliability is improved, and the market competitiveness of the product is enhanced.
本发明公开了一种防火锁主锁舌结构的成型工艺，其包括以下步骤：将铁卷料利用连续模下料冲压生产加工成一端具有折弯部的方舌板，折弯部用于安装固定方舌板摆杆弹簧的一个固定脚；将方舌头连接在方舌板上。通过本申请的防火锁主锁舌结构，能彻底有效的解决原结构弹簧铆钉铆接不良脱落的问题，同时能减少锁体的物料用量，减少一道铆接工序，从而一定程度上降低了产品成本，提高产品的可靠性，从而增强了产品的市场竞争能力。
