序言目前,在加工技术中,零件的冷、热成形方法已具有很重要的地位。某些传统的加工方法已部分地被成形法所代替。众所周知,成形工艺的优点是节省材料、尺寸精度与形状精度高、表面质量好、制造时间短、自动化程度高、生产节奏短。当然,齿轮的无屑加工,也力求吸收这些优点。齿形和螺纹制造的特点是,把工件的外表面压成具有一定斜度(与工件轴线成0～90°)的一个或多个凹槽。基于齿形和螺纹的这种关系,可在现有的螺纹轧制机床上进行齿轮加工,齿轮模数为1.5毫米以下。对于较大模数的齿形加工,因有较大的金属变形,只能在专用的机床上才能进行加工,也就是说,机床的运动机构必须与工件材料的较大变形相适应。为了加工不同的内、外齿形,专门研制了成形机床。
Preamble Currently, in the processing technology, parts of the cold, hot forming method has an important position. Some traditional processing methods have been partially replaced by forming methods. As we all know, the advantages of forming process is to save material, high dimensional accuracy and shape accuracy, surface quality, manufacturing time is short, high degree of automation, short production pace. Of course, gearless chip processing, but also strive to absorb these advantages. Tooth shape and thread manufacturing is characterized by the outer surface of the workpiece is pressed into a certain gradient (with the workpiece axis 0 to 90 °) of one or more grooves. Based on this relationship between teeth and threads, the gear can be machined on an existing thread rolling machine with a gear modulus of 1.5 mm or less. For larger modulus of tooth machining, due to the larger metal deformation, can only be processed on a dedicated machine, that is, the machine tool movement must be compatible with the larger deformation of the workpiece material. In order to process different internal and external tooth profile, specially developed forming machine.
