液压螺旋锤是近十年来出现的新型锻压设备。它的工艺使用范围较广、模锻、挤压、校正、薄壁锻件的锻造等工艺均可以在液压螺旋锤上进行。也适用于有色金属及其合金的锻造。由于机器的运动特性和有比较高的锻造速度,最适合于精密模锻。它比热模锻曲柄压力机具有更高的模锻精度。目前许多国家在工业生产中都大量采用和推广液压螺旋锤,并逐步用液压螺旋锤在许多情况下取代现行的热模锻曲柄压力机,摩擦压力机、模锻液压机和锤。下面分三部分介绍:
Hydraulic hammer is the emergence of a new type of forging equipment over the past decade. It uses a wide range of processes, forging, extrusion, calibration, forging and other thin-walled forging process can be carried out on the hydraulic hammer. It is also suitable for forging of non-ferrous metals and their alloys. Due to the machine’s kinematic characteristics and higher forging speed, the most suitable for precision die forging. It has higher die forging precision than hot-die forged crank presses. At present, many countries in the industrial production are extensive use and promotion of hydraulic screw hammer, and gradually with the hydraulic screw hammer in many cases to replace the existing hot die forging crank press, friction press, forging hydraulic press and hammer. The following is divided into three parts:
