Description

一种多车串联同步定尺切断连续成型物料的新方法 技术领域
本发明专利涉及钢管、型钢等连续成型物料生产线领域，切断机在与生产线速度同步的状态下，按照设定的长度切断物料的新方法，具体是一种多车串联同步定尺切断连续成型物料的新方法。
背景技术
以往钢管、型钢等连续成型物料生产线上的切断机大部分都是采用单车同步定尺切断机，只有一台装有割具的车，当物料走过设定的长度时，车在平行于物料的轨道上，从原点出发，跟踪物料行走，当车与物料的速度达到同步时，车上的割具切断物料，然后车返回到原点，准备进行下一次切割。车的行程小于物料的定尺长度，以确保在一个切割过程结束后有足够的时间返回原点。生产线的速度越快，物料的定尺长度越短，割具切割物料的时间就越短。这种切断机不适合切短尺产品，也不适合高速生产线，否则由于切割时间短，使得物料的切口质量变差、割具的寿命变短。因此，开发一种新型的切断方法是十分必要的。
发明内容
为了克服现有技术的不足，本发明专利提出了一种多车串联同步定尺切断连续成型物料的新方法。本发明的具体技术方案是：有两台或两台以上装有割具的车，这些车串联的安装在平行于物料的轨道上，在各自的驱动装置驱动下，按照设定的程序往复行走，在与物料速度同步的情况下，车上的割具按照设定的长度切断物料。为了方便描述，下面以图1所示的双车串联同步定尺切断机为例，说明其工作过程。
双车串联同步定尺切断机见图1：
双车串联同步定尺切断机有两台车，车1和车2串联的安装在与物料3平行的轨道4上，所述车1和车2可以在同一轨道上，也可以是在各自的轨道上，见图5，轨道4的下面有固定底座8。车1和车2在各自的驱动装置5、6的驱动下，按照设定的程序在轨道上往复行走，车1上装有割具7，车2上装有割具9，均用于切割物料3。该切断机的一个切割工作循环如下：
见图1，在物料3连续成型的过程中，物料3进入车2的切断范围且达到设定的长度时，驱动装置6启动，带动车2从起点加速，当车2与物料3的速度达到同步时，车2上的割具9开始切割物料3；见图2，当继续前行的物料3进入车1的切断范围且达到设定的长 度时，驱动装置5启动，带动车1从起点加速，当车1与物料3的速度达到同步时，车1上的割具7开始切割物料3；见图3，车2切断物料3后返回起点；见图4，车1切断物料3后返回起点；随着物料的连续成型，切断机不断的重复以上工作过程，按照设定的长度切断物料。由上可见，与单车同步定尺切断机相比，双车串联同步定尺切断机的车的行程可以长于物料的定尺长度；并且对于双车串联同步定尺切断机的每台车而言，一个切割周期是生产线生产两根物料的时间，在生产二根物料的过程中每台车只有一次加速和减速过程。而单车同步定尺切断机的车的行程必须短于物料的定尺长度，一个切割周期是生产一根物料的时间，生产二根物料的过程中车有两次加速和减速过程。由此可见，双车串联同步定尺切断机比单车同步定尺切断机有多得多的时间用于切割物料。因此，在生产线速度、定尺长度相同的情况下，双车串联同步定尺切断机的切口质量更好，割具寿命更长；或者说，在切口质量和割具寿命相同的情况下，双车串联同步定尺切断机的生产线速度能够做得更高，物料的定尺长度能够做得更短；还有，在相同数量的产品的情况下，双车串联同步定尺切断机的每个割具的工作次数比单车同步定尺切断机减少一倍，所以生产线因更换割具而停机的次数少，有利于提高生产线的效率，减少废品损失。
多车串联同步定尺切断机，其工作原理与上面所述的双车串联同步切断机雷同，有两台或两台以上的车，这些车串联的安装在平行于物料的轨道上，所述轨道可以是同一轨道，也可以是各自的轨道，轨道可以在物料的一侧或两侧。这些车在各自的驱动装置驱动下，按照设定的程序往复行走，并在速度同步的情况下按照设定的长度切断物料。车的数量越多，车的行程就可以做得越长，割具用于切割物料的时间就越多。这种切断机适应的生产线速度高，允许的最小定尺长度小，割具的寿命长，切口的质量好，更换割具停机的次数少。
附图说明
附图1是本发明具体实施例中车1在起点，车2跟踪并切割物料3的示意图
附图2是本发明具体实施例中车1、车2跟踪并切割物料3的示意图
附图3是本发明具体实施例中车1跟踪并切割物料3，车2切割结束后返回的示意图
附图4是本发明具体实施例中切割结束后车1、车2返回的示意图
附图5是本发明拥有不同轨道的示意图
附图6是车1割具不切割时的示意图
附图7是车1割具切割时的示意图
具体实施方式
现在结合多车串联同步定尺切断机的形式之一，双车串联同步定尺切断机，对本发明的实施例作进一步描述：双车串联同步定尺切断机，主要由车1、2，轨道4，底座8，驱动装置5、6，割具7、9组成。车1、2串联的安装在与物料3平行的轨道4上，所述轨道可以是同一轨道，也可以是各自的轨道，在驱动装置5、6的驱动下，按设定的程序在轨道4上往复行走，在与物料速度同步的情况下，车上的割具按照设定的长度交替的切断物料3。见图1，车1停留在自己的起点，物料3进入车2的切断范围且达到设定的长度时，驱动装置6启动，带动车2从起点加速，当车2与物料3的速度达到同步时，车2上的割具9开始切割物料3；见图2，当继续前行的物料3进入车1的切断范围且达到设定的长度时，驱动装置5启动，带动车1从起点加速，当车1与物料3的速度达到同步时，车1上的割具7开始切割物料3；见图3，车2切断物料3后返回起点；见图4，车1切断物料后返回起点。双车串联同步定尺切断机周而复始的重复以上工作过程，按照设定的长度切断物料。
同理，多车串联同步定尺切断机，有两台或两台以上的车，这些车串联的安装在平行于物料的轨道上，所述轨道可以是同一轨道，也可以是各自的轨道，轨道可以在物料的一侧或两侧，这些车在各自的驱动装置驱动下，按照设定的顺序往复行走，并在速度同步的情况下按照设定的长度切断物料。车的数量越多，车的行程就可以越长，用于切割物料的时间就越多。这种切断机适应的生产线速度高，允许的最小定尺长度小，割具的寿命长，切口的质量好，更换割具停机的次数少。
