Abstract
The invention discloses a forging process for a lock case. The forging process includes the steps of discharging and heating, wherein a blank is arranged in an intermediate-frequency furnace to be heated at the temperature of 1,240 DEG C to 1,290 DEG C; blank forming, wherein the heated blank is manufactured into the shape basically similar to that of a pre-forging cavity through measures such as die forming and flattening; pre-forging, wherein the blank obtained after blank forming is arranged in a pre-forging die to be pre-forged; finish forging, wherein the pre-forged blank is arranged in a finish forging die for finish forging; edge cutting, wherein an edge cutting die is designed, and a lock case forging is subjected edge cutting, and burrs are removed; and heat treatment, wherein the surface of the lock case forging is subjected to shot blasting, and then subjected to thermal refining. The forging process has the beneficial effects that the process steps are simple, production cost is low, production efficiency is high, the quality of the lock case forging is stable, and the yield is high.
Description
Technical field
The present invention relates to Forging Technology, especially a kind of lock housing Forging Technology.
Background technology
Be generally foundry goods with the lock housing that locking bolt is supporting, but the lock housing of foundry goods exists a lot of defect to be difficult to make up, and therefore make lock housing foundry goods into forging, but lock-shell structure is complicated, forging difficulty.
Summary of the invention
The object of this invention is to provide a kind of steady quality, the lock housing Forging Technology that productivity effect is high.
For achieving the above object, the technical solution adopted in the present invention is: a kind of lock housing Forging Technology, comprises blanking heating, base, blocking, finish-forging, trimming, heat treatment successively, it is characterized in that:
Blanking is heated: loaded in intermediate frequency furnace by blank and heat, heating-up temperature is 1240 DEG C-1290 DEG C;
Base: the blank after heating is made the shape with blocking die cavity basic simlarity by the means such as die forging, flattening;
Blocking: carry out blocking in the blank loading Preform Die completed by base;
Finish-forging: carry out finish-forging in the blank loading finish-forging die completed by blocking;
Trimming: design a shaving die, carry out trimming process to lock housing forging, removes burr;
Heat treatment: ball blast is carried out to lock housing forging surface, then carries out modifier treatment.
Before blocking and finish-forging, carry out preheating to Preform Die, finish-forging die, preheat temperature is 200 DEG C-250 DEG C, and with gypsum breast lubricated dies.
Described blocking adopts hotdie forging press forging, and blocking temperature is 1150 DEG C-1200 DEG C, and blocker forging pressure is 6500T-7000T.
Final forging temperature is 900 DEG C-1000 DEG C, and finish forging pressure is 6000T-6500T.
The present invention adopts above-mentioned technique, and not only processing step is simple, production cost is low, production efficiency is high, and the steady quality of lock housing forging, and yield rate is high.
