2000 tons bucket tooth forging equipment die forging forming hydraulic press
锻造斗齿利用锻压机械对特殊金属坯料施加压力，在高温下挤压成型，细化锻件中的晶料，使其产生塑性变形以获得具有一定机械性能，金属经过锻造加工后能改善其组织结构，可以保证锻造斗齿具有良好的力学性能、更耐磨，使用寿命更长。
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.
大型挖局机斗齿属于重要易耗部件，类似于人的牙齿，由齿座和齿尖组成，齿尖在日常加工生产中更容易损坏，其制造工艺分为沙铸造、锻造、精密铸造。在热锻造过程中需要使用较大吨位的压力机、模具配合完成锻造加工生产。山东众友重工设计制造的2000吨四柱液压机用于热锻压成型加工，客户就是加工这种挖掘机斗齿的。目前设备正常使用中，加工效率高、节能环保、无故障客户满意度高。采购热锻造成型液压机设备，详情咨询丁经理：13562463338（可加微信）。
