2000 tons bucket tooth forging equipment die forgingforming hydraulic press
Forged bucket tooth utilizationforging pressMachinery applies pressure to special metal blanks and extrudes them at high temperatures to refine the crystal material in the forgings to produce plastic deformation to obtain certain mechanical properties. The metal can improve its organizational structure after forging processing, which can ensure forging The bucket teeth have good mechanical properties, are more wear-resistant, and have a longer service life.
2000 tons of four-column hydraulic press forging forklift/excavator bucket tooth process:
The blanking process adopts precision blanking, and the blanking tolerance of the length of the blank is ± 0.5mm.
The heating process adopts medium frequency induction heating, and the heating temperature is 1150 ℃, so that the surface of the workpiece is rapidly heated and the formation of oxide skin is reduced.
Upsetting process, blank upsetting to remove the surrounding oxide skin, and air blowing to remove the upper and lower oxide skin, improve the surface quality of forgings and improve the life of the mold, and keep the ratio of blank length to diameter less than 2.5 when upsetting.
In the closed compound extrusion process, the upper die moves downward with the sliding block of the hydraulic press to compress the blank until the metal fills the whole cavity. The bucket tooth blank is formed by the lower compound extrusion of the upper die in the die. The 1500-ton four-column hydraulic press sliding block returns to form the extrusion part, and the whole extrusion process ends.
2000 tons bucket teeth forging equipment die forging hydraulic press design features:
1. The hydraulic system has automatic protection devices such as multi-level overload protection, oil temperature alarm and oil level alarm protection. The electrical system adopts mature PLC control to ensure the safety of equipment and operators.
2. The pressing down working cylinder adopts a large flow filling valve and an auxiliary oil tank to supply liquid at the same time, which can realize rapid oil filling, oil replenishment and oil return during lifting, effectively saving short auxiliary time and improving forging efficiency.
3. The equipment is equipped with a reliable cooling circulation system, which can stably control the temperature rise and ensure the safe and reliable operation of the system.
4, the slider stroke is certain, each die forging step only one stroke to complete. The metal deformation is completed in one stroke of the slider, and the inner and outer layers of the blank are deformed almost at the same time, so the deformation is deep and uniform, the mechanical properties of the forgings are basically the same, and the streamline distribution is more uniform, which is conducive to improving the internal quality of the forgings. At the same time, due to the fixed stroke, it is not suitable for drawing long river rolling and other billet-making steps, but can only complete the billet-making operation with little change in cross section;
5, the use of 1000 tons of four-column hot forging hydraulic press for overall forging, and normalizing treatment and removal of oxide scale.
The bucket teeth of large-scale machine are important consumable parts, similar to human teeth, which are composed of tooth seats and tooth tips. The tooth tips are more easily damaged in daily processing and production. Its manufacturing process is divided into sand casting, forging and precision casting. In the hot forging process, it is necessary to use a larger tonnage press and die to complete the forging process.
