轧环机又称扩孔机,英文:Staving Press.是加工环形锻件的先进设备,广泛应用于轴承、工程机械、石油化工、航空航天、发电等工业领域的环形件生产。
碾环机,英文是Ring rolls.
液压挤孔机气液增压缸是结合是气缸和油缸优点而改进设计的,液压油与压缩空气严格隔离,www。xhzhjx。com缸内的活塞杆接触工作件后自动启程,液压挤孔机动作速度快,且较气压传动稳定,缸体装置简单,出力调整容易,相同条件下可达到油压机之高出力,能耗低,软着陆不损模具,安装容易并且特殊增压缸可360度任意角度安装,所占用的空间小,故障少无温升之困扰,寿命长,噪声小,等核心特性。
组合机床 组合机床是以通用部件为基础,配以按工件特定形状和加工工艺设计的专用部件和夹具,组成的半自动或自动专用机床。 [编辑本段]组北装排括材案帝适合机床加工方式 组合机床拉环艺研陆承海华一般采用多轴、多刀、多工序、多面或多工位同时加工的方式,生产效率比通用机床高几倍至损跳响罗大村含几十倍。由于通用部件已经标准化和系列化,可根据需要灵活配置,能缩短设计和制造周期。因此,组合机床兼有低成本和高效率的优点,在大批、大量生产中得到广泛应用,并可用以组成自动生产线。
组合机床一般用于加工箱体类或特殊形状的零件。加工时,工件一般不旋转,由刀具的旋转运动和刀具与工件的相对进给运动,来实现钻孔、扩孔、锪孔、铰孔、镗孔、铣削平面、切削内外螺纹以及加工外圆和端面等。有的组合机床采用车削头夹持工件使之旋转,由刀具作进给运动,也可实现某些回转体类呢编演述应质是出适零件(如飞轮、汽车后桥半轴等)的外圆和端皇皮剂怕扩导均散状胞面加工。 组合机床部件分类 通用部件按功能可分为动力部件、支承部件、输送部件、控制部件和辅助部件五类。动力部件是为组合机床提供主运动和进给节战需该求运动的部件。主要有动力箱、切削头和动力滑台。
支承部件是用以安装动力滑妈粒加减台、带有进给机构的切削头或夹具等的部件,有侧底座、中间底座、支架、可调支架、立柱和立柱底座等。
输送部件是用以输送工件或主轴箱至加工工位的部件,主要有分度回转工作台、环形分度回转工作台、分度听死鼓轮和往复移动工德就革谁作台等。
控制部件是用以控制机床的自动工作循环的部件,有液压站、电气柜和操纵台等。辅助部件有润滑装置、冷却装置和排屑装置等。 组合机床的发展 为了使组合机床能在中小批量生产中得到应用,往往需要应用成组技术,把结构和工艺相似的零件集中在一台组合机床上加工,以提高机床的利用率。这类机床常见的有两种,可换主轴箱式组合机床和转塔式组合机床。
组合机床未来的发展将更多的采用调速电动机和滚珠丝杠等传动,以简化结构、缩短生产节拍;训从怀脱促现采用数字控制系统和主轴箱、夹具自动更换系统,以提高工艺可调性;以及纳入柔性制造系统等。 Combination machine toolsCombination machine tools i并吃掉形团列轮袁章s based on general parts, according to 药必the specific shape and workpiece machining process of the special components and fixture design, semi-automatic or automatic special machine. [editor this segment] combination machine tools machining combination ma介哪玉非想皇聚跟苗叶翻chine tools usu静末应菜背原冲掌境ally adopts t名he multiaxial, kn百硫跟二要不伤善ife, more processes, and multi-faceted or multistage and processing, production efficiency than general machine high several times or more. Due to the standardization and serialization general parts have, can acc阿造广孙ording to need flexible configuration, can shorten the cycle of design and manufacture. Therefore, the combination machine has the advantages of low cost 欢因轴想and high efficiency, in large, large production is widely used, and the automatic production line can be used to composition.
Combination machine tools for processing general box or special shape of parts. Processing, workpiece rotate, generally by the tool and workpiece rotate movement and tools for the relative motion, to realize in drilling, reaming, economic hole, reaming, boring, cutting and milling, and the processing thread and fiber-end surface etc. Some combination machine adopts clamping workpiece machining head to rotate, feeding movement by the tool for, also can achieve some axisymmetrical parts (such as the flywheel, automobile rear half axle, etc.) of the circle and the process.Combination machine parts classificationGeneral parts according to the function can be divided into power components and parts, transmission parts, supporting the control and auxiliary parts. Power components are provided for combination machine tools in the movement and moving parts. Main motivation, cutting head and dynamic slide.
Supporting components are installed power to slide into to institutions, cutting head or fixture, have side base, base, support, adjustable bracket, column and column base, etc.
Transmission parts is used to transport or spindle box to the processing of the main parts, workstation dividing rotating table, the annular dividing rotating table, drum and to-and-fro moving workbench, etc.
Control components are used to control the machine parts, automatic working cycle is hydraulic pressure station and electrical cabinets and control console, etc. Auxiliary parts are lubrication device and cooling device and scraps discharge device etc.The development of modular machine tool
In order to make the combination machine tools in small batch production, often applied to the structure, the application of group technology and craft of similar parts in a centralized modular machine tool, in order to improve the machining efficiency. This machine has two kinds of common, spindle box combination machine tools and turn tower combination machine tools.
Combination machine tools of future development will be more adopts stepless motor and transmission of ball screw, etc, to simplify structure and shorten the production beat, Using digital control system and spindle box, jig automatic replacement system, in order to improve the process adjustability, Flexible manufacturing systems and into.
