L31系列外榫槽拉床 L31 Turbine Disc Surface Broaching Machine
    发布时间: 2019-02-27 15:49    

L31系列榫槽拉削机床主要用于大型涡轮盘榫槽加工,机床采用液压传动,工作平稳,能无极调速。带自动让刀机构。具有自动循环、半自动循环、分段循环和手动操作四种工作状态。手动状态下对主溜板的工作和返回以及各单步动作均可进行单独操作。

L31 turbine disc surface broaching machine is specially designed to machine the mortise in large-size turbine disc. This machine features hydraulic drive, stable performance, stepless speed adjustment and automatic cutter relieving unit. It has four work modes: automatic cycle, semi-automatic cycle, segmented cycle and manual operation. Under manual operation mode, each single action can be operated individually, such as the working and returning of main slide carriage.

用途和特点 

L31系列榫槽拉削机床主要用于大型涡轮盘榫槽加工,机床采用液压传动,工作平稳,能无极调速。带自动让刀机构。具有自动循环、半自动循环、分段循环和手动操作四种工作状态。手动状态下对主溜板的工作和返回以及各单步动作均可进行单独操作。
    
机床采用大跨度拉削力设计,适用拉削力从250KN1000KN,拉削零件品种广,根据不同的零件来选择机床的液压运行方式。机床采用PLC加控制模块组成CNC控制方式。具有手动及自动的工作方式,操作方便。采用数控系统控制显示、计数、报警、位移及故障诊断。机床的运行速度:在显示屏上,输入需要的速度数值,机床即可按给定的速度运行。机床的运行行程:在显示屏上,输入对应的行程位置,无需移动传感器。
    
该机型采用全闭环数控分度方式,该分度方式既能进行连续分度且旋转精度可进行反馈调节,分度盘内有夹紧装置,能定位且可抵抗较高的倾覆力矩。船台导轨采用弧形燕尾槽导轨,船台采用全闭环位置控制使机床达到高精度。

Applications and Advantages

L31 turbine disc surface broaching machine is specially designed to machine the mortise in large-size turbine disc. This machine features hydraulic drive, stable performance, stepless speed adjustment and automatic cutter relieving unit. It has four work modes: automatic cycle, semi-automatic cycle, segmented cycle and manual operation. Under manual operation mode, each single action can be operated individually, such as the working and returning of main slide carriage.

The machine is designed with large span broaching forces from 250 - 3000 KN, which allow it broach a wide variety of parts as the operation modes of hydraulic system can be selected according to different parts. The CNC system consists of PLC and control module. The machine is convenient in operation as it can be operated automatically and manually. CNC system is employed to realize functions like control, display, count, alarm, displacement data reading and fault diagnosis. Machine work speed setting: input the value of speed on display screen and machine will work at the given speed. Machine stroke length setting: input the position coordinate of stroke length on display screen without moving sensors.

    This type of machine adopts a full closed-loop CNC indexing method which can realize continuous indexing and make rotary precision be adjustable. The clamping device mounted in index plate can realize position and resist overturning moment. The machine bed adopts arc-shaped dovetail groove guide rail and full closed-loop position control, providing the machine with high precision.
