基于弹簧增压机构的电缆外护套环切机械的研制

Development of Cable Outer Sheath Ring Cutting Machine Based on Spring Supercharging Mechanism

厚度检测前制备样品时,要对电力电缆非金属外护套厚度进行测量。针对原由人为切取薄片造成切割截面质量差,容易被锋利的刀具伤手,外护套难以割取等问题,提出一种面向护套环形截面取样的全自动机械设备。这种机械设备利用弹簧机构蓄能,工作时通过滚珠丝杆驱动刀头,调节压力输出,达到非真圆环切制取护套样品。本文将电缆外护套环切机械应用于实际工作场合,结果表明,样品制取效率大幅提高,截面切割优质,人力工作大幅降低,制取便捷,操作方便,且满足测量要求,无残缺现象。

For the non-metallic outer sheath thickness measurement of power cables, it is used for the sample preparation before the thickness detection. Aimed at the problem that the quality of cutting section is poor, which is easy to be hurt by sharp knives, and the outer sheath is difficult to cut, a fully automatic mechanical equipment for sampling the annular section of sheath is proposed. This kind of mechanical equipment uses the spring mechanism to store energy. When it works, it drives the cutter head through the ball screw, and adjusts the pressure output, so as to make the sheath sample by non true circular cutting. In this paper, the cable outer sheath ring cutting machine is applied to the actual work situation. The results show that the efficiency of sample preparation is greatly improved;the section cutting is high quality;the manpower work is greatly reduced;the preparation is convenient;the operation is convenient;and it meets the measurement requirements, without defects.
