Forging production process

Before the forging deformation process are mainly blanking and heating process. Blanking process according to the size of the preparation of the original blank forging need, when necessary, but also to the original blank derusting, in addition to the surface defects, anti-oxidation and lubrication, etc; Heating process according to the forging deformation required by heating temperature and heating production rhythm of the original blank.

After forging deformation process after forging deformation, followed by cooling process of forging. Then, in order to supplement the shortage of the previous process, make the forgings fully meet the requirements of the forging product figure was needed: trimming punching (to die), heat treatment, correction, surface cleaning, etc. Sometimes, will be closely combined with cooling after forging and heat treatment process, in order to obtain certain forgings organization performance.

In the existing wheel processing process, after the wheels are rough, they need to be polished, and then the bottom paint is sprayed, painted, and refined. Because a large amount of metal and abrasives are generated during polishing, the wheels need to be cleaned before spraying the primer. However, in the existing technology, once the water remains on the wheels after washing, the paint spraying and the subsequent paint effect will be affected, and in the existing technology, the wheels will be cooled naturally after removing from the oven. The baking temperature is generally 140 ° C ~ 180 ° C. The baking time and natural cooling time are long. Generally, it takes 15 minutes to 30 minutes and 5 minutes to 10 minutes.
