Bucket teeth are an important part of the excavator. They are similar to human teeth and are also wearing parts. They are a combination bucket tooth composed of a gear seat and a tooth tip, and the two are connected by a pin. The process of bucket teeth is generally casting and forging. Among them, the cost of casting is low and the technology level and bucket tooth quality are not as good as forging. Although forging is higher in cost, the technology level and bucket tooth quality are better. The specific process of bucket tooth forging is: blanking - heating - upsetting - extrusion - punching and typing - residual temperature quenching, etc. The heating process is mostly carried out by medium frequency diathermy equipment, and the effect is very good.
The forging process of bucket teeth is:
1. Blanking: Precision blanking is adopted, and the length blanking tolerance of the blank is ±0.5mm.
2. Heating: Medium frequency diathermy equipment is used, and the heating temperature is 1100℃-1200℃, which can quickly heat the surface of the workpiece and reduce the formation of oxide scale.
3. Upsetting: In the upsetting process, the ratio of blank length to diameter is less than 2.5.
4. Closed compound extrusion: The closed hot extrusion die used is a two-layer combined heat-coated film.
5. Composite punching and typing: A self-made fully hydraulic automatic control punching and typing machine is used to automatically complete the punching and typing processes in one go.
6. Post-forging residual heat treatment: Use the residual temperature of the hot bucket tooth forgings after forging for quenching treatment.
This article briefly introduces the bucket tooth forging production line, hoping to be helpful to your work. If you want to know the specific process, you can read books on heat treatment. I believe you will gain a lot.
