Tractor is the most commonly used power machine in agricultural production. The modern advanced type of machine uses its suspension system to realize the automation of various agricultural machines. The tractor suspension system is an important structure for the expansion of tractor functions, providing traction and control functions for other agricultural implements. After years of development, the tractor’s rear suspension system not only forms a perfect mechanical structure, but also through the continuous upgrading of electronic control and hydraulic system, with updated functions, understanding and mastering the structure and function of the modern tractor rear suspension system, which is beneficial to Improve the working ability of the tractor driver and ensure the smooth progress of agricultural production.
Gold emperor’s custom tractor suspension forgings are mainly closed-die forging. Tractor suspension forgings has the following advantages compared to other methods.
Sometimes, there are many ways to manufacture a item, and we need to evaluate each one before ordering. Below we will show how closed die forging compared to open die forging, investment casting, and machining.
Closed Die Forging vs Open Die Forging
In open die forging a cylindrical billet is subjected to upsetting between a pair of flat dies or platens. Under frictionless homogeneous deformation, the height of the cylinder is reduced and its diameter is increased. Forging of shafts, disks, rings etc are performed using open die forging technique. Square cast ingots are converted into round shape by this process.
Closed die forging is a precision forging process for its precise tooling or dies, while open die forging is free forging with simple tooling. So closed die forging can provide much more precision components, specially for small and medium parts. And open die forging is only for large products.
Closed Die Forging vs Investment Casting
Different from closed die forging, investment casting is the casting method by pouring liquid metal into molds to form the shapes. The same point of these two methods is that both of investment casting and closed die forging can manufacture components in accurate dimensions and tolerances. But defects may be easily produced by investment casting, which could be effectively avoided in closed die forging.
Another advantage of closed die forging is that, the pressing operation of billets will greatly increase the strength of products. So closed die forging is especially suitable for components in safety consideration, such as lifting & rigging hardwares.
Closed Die Forging vs Machining
For simple shaped parts, machining from bars directly is also the option for desired dimensions. Compared with closed die forging, there will exsit large amounts waste of raw material. Also, the properties and working performance of closed die forged components will be much better than machined ones.
Closed Die Forging Application
Closed die forging is mainly used for the production of steel and aluminum components. So the application of closed die forging is wide. It coud be used forAutomobile industry, electric power industry, railway locomotive, petrochemical industry,the production of mining drilling bits, forestry wear parts, agricultural wear parts, construction wear parts, rigging and lifting components, ect. In a word, Any application requires high quality components could adopt this type of method.
