Razne Metode Of Titan Kovanje

According to the way the billet moves, forging can be divided into free forging, upsetting, extrusion, die forging, closed die forging, and closed upsetting forging. Because there is no flash in closed die forging and closed upsetting, the utilization rate of materials is high. It is possible to complete the finishing of complex forgings in one or several processes. Since there is no flash, the force-bearing area of the forging is reduced, and the required load is also reduced. However, it should be noted that the billet cannot be completely restricted. For this reason, the volume of the billet should be strictly controlled, the relative position of the forging die should be controlled and the forging should be measured, and efforts should be made to reduce the wear of the forging die.

Accord to the movement mode of the forging die, kovanje can be divided into oscilating rolling, oscilacating kovanje, roll kovanje, cross wedge rolling, ring rolling and cross rolling. Oscillating rolling, oscilacating kovanje i rolling can can also be processed by precision kovanje. In order to improve material utilization, roll forging and cross rolling can be used as front-end processing of slender materials. Rotary kovanje% 2c like open forging, is also locally formed. Its advantage is that it can be form with a small kovanje force compared to the size of the kovanje. In this kind of kovanje metoda uključujući free kovanje, the material expands from the ne blizina of the die surface to the free surface during processing, so it is difficult to ensure the accuracy. The kovanje power is used to obtain products with complex shapes and high precision, such as kovanja such as steam turbine blades with many varieties and large sizes.

The materials used for titanium forging are mainly pure titanium and titanium alloys of various components. The original states of the materials include bar stock, ingots, metal powder and liquid metal. The ratio of the cross-sectional area of the metal before deformation to the cross-sectional area after deformation is called the forging ratio. Correct selection of forging ratio, reasonable heating temperature and holding time, reasonable initial forging temperature and final forging temperature, reasonable deformation amount and deformation speed have a great relationship with improving product quality and reducing cost. Generally, small and medium-sized forgings use round or square bars as blanks. The grain structure and mechanical properties of the bar are uniform and good, the shape and size are accurate, and the surface quality is good, making it easy to organize mass production. As long as the heating temperature and deformation conditions are reasonably controlled, forgings with excellent performance can be forged without large forging deformation.
