The difference between hot forging and cold forging in forging forming hydraulic press?
Inforging forming hydraulic pressAccording to the different forging processes, it is divided into hot forging forming hydraulic press and cold forging forming hydraulic press. In order to facilitate everyone to purchase suitable models, Shandong belowZhongyou Heavy IndustryHydraulic press manufacturers make a brief introduction to the difference between hot forging and cold forging.
Hot forging:
Processing at a higher recrystallization temperature than the billet metal is called hot forging. Increasing the temperature in hot forging can improve the plasticity of the metal, which is beneficial to improve the internal quality of the workpiece and make it difficult to crack.
High temperatures also reduce the deformation resistance of the metal and reduce the needforging pressThe tonnage of the weapon. But the hot forging process, the workpiece accuracy is poor, the surface is not smooth, forgings are prone to oxidation, decarburization and burning. In precision forging, hot forging process is often combined with cold forging and warm forging to form a cold and hot composite precision forming process.

Cold forging:
Forging of parts at room temperature is called cold forging. The cold forging process is a precision plastic forming technology and a (near) net forming process. Cold forging has unparalleled advantages in machining, such as good mechanical properties of products, high productivity and high material utilization, especially suitable for mass production, and can be used as a manufacturing method of final products, in transportation, aerospace and machine tool industries and other industries have a wide range of applications. At present, the rapid development of automobile industry, motorcycle industry and machine tool industry has provided the driving force for the development of cold forging technology.
Shandong Zhongyou Heavy Industry Machine Tool Co., Ltd. customizes various hot forging and cold forging forming hydraulic press equipment on demand. This series of products have fast working speed and are equipped with automatic mold spraying and lubricating systems. The hydraulic system adopts electro-hydraulic proportional servo system with high pressure accuracy and high positioning accuracy to meet the needs of different processes for hydraulic presses. Die forgings can achieve less cutting or no cutting, high efficiency and low cost of producing workpieces, and are being used more and more in machining.
