通常,高速钢、超耐热不锈钢等钢种锻造比较困难,锻件容易产生裂纹。奥地利 GFM 公司制造了一种数控四锤头旋转锻锤,能够象锻造碳钢一样对高速钢、超耐热不锈钢等钢种进行锻造加工。这种转雠锻锤,最大的一台安装在美国,能锻造具工作温度范围很窄的难于锻造的钢,锻件的断面形状可以是圆形、方形、矩形和多边形的,并且锻件具有极好的同心度,而且表面不会产生裂纹。据使用该设备的美国卡本特技术公司介绍,这种设备有如下特点:1.旋转锻造时,坯料受到的拉应力最
Usually, high-speed steel, super heat-resistant stainless steel and other types of forging more difficult forgings prone to cracking. GFM, Austria, manufactures a CNC four-hammer rotary hammer that can forge steels such as high-speed steel and super-heat-resistant stainless steel, just as forged carbon steel. This swivel forging hammer, the largest of which is installed in the United States, can be forged with difficult to forge steel with a narrow operating temperature range. The cross section shape of the forgings can be round, square, rectangular and polygonal, and forgings have excellent Concentricity, and the surface will not crack. According to the use of the equipment, the United States Cabot technology company introduced this device has the following characteristics: 1. Rotary forging, the billet suffered the most tensile stress
