一种管材切割生产线及生产方法 技术领域
本发明涉及管材切割设备领域，尤其涉及一种管材切割生产线及生产方法。
背景技术
随着市场经济的快速发展，管材的应用领域也越来越广泛，不同的领域对管材的规格、形状、长度以及切割要求都不相同，越来越多的厂家不仅对管材上料、管材加工有较高要求，甚至对于下料也有了更高的要求，不再满足于零散下料，人工码料的形式。市面上的激光切管系统，大都是半自动上料或全自动成捆上料，零尾料切割或切割尾料较长，配套的自动下料系统，基本都是切割完成的管材从斜坡滑落至收料仓中，由两个工人一根根抬至小车上，一层层码料摆放整齐，再打包好运送至其他存放区域，效率低，劳动强度大，不符合快速、高效的市场需求。
因此针对现有技术不足，需要发明一种能成捆管材全自动上料、能实现零尾料、且成品管材能够自动下料、自动码垛的切管系统，全程无需人工干预，用以适应越来越智能化、自动化的市场要求。

如图1-图12所示，本具体实施方式在具体实施方式1的基础上提供了一种管材切割生产方法，主要包括以下步骤：
A1：将成捆的管材放到上料栈102中，上料栈102中的管材在卷料带1202的带动下被送往第一链条上；
A2：限高板113下降，将第一链条上的管材摊平；
A3：第一链条上的管材向前输送，当第一根管材传送至第二链条时，第一链条停转，仅这一根管材沿第二链条向前输送；第二链条将管材送至顶升机构105处，顶升机构105带动管材升至一定高度；
A4：测长机构106测量管材长度后回原点，根据管材长度，系统命令对应数量的夹管机构104夹取管材；
A5：夹管机构104将管材送到切割床身201上，由支撑组件对管材进行支撑；
A6：第一尾卡203夹持住管材尾端，拖动管材前移至中卡204，中卡204夹持管材首端，进入切割过程；
A7：随着第一尾卡203前移，支撑组件逐次下落，让出移动空间，直至该根管材切割完成；
A8：切割后符合规定长度的管材通过第二尾卡205夹1403持，并被拖动到下料端，下料架3上的接引臂接引管材，并将管材送至传动组件302上；
A9：传动组件302将管材输送至推管组件303处，通过推管组件303将管材推至挡管销处；
A10：达到打包宽度所需的管材数量时，挡管销落下，限位杆307及托杆308升起，推管组件303将一排管材推送至托杆308上，并靠齐限位杆307；
A11：左推板306推动管材使管材的端面顶在右挡板312上，使得一排管材对齐；
A12：升降台305升起，至托杆308高度，托杆308缩回下料架3，管材被平整放置于升降台305上，升降台305下落一个管材高度；
A13：托杆308伸出，重复步骤A10-A12的步骤，一排排管材整齐码至升降台305上；
A14：当码至打包高度所需的管材数量时，升降台305下落，管材被放置到码料小车311上；
A15：码料小车311两侧挡杆升起，将管材码垛整齐成包，沿地轨309移动至指定区域。
其中，伸出中卡204的长度大于1米时，第二尾卡205夹1403持管材前端，防止管材前端下垂影响加工精度，此时三个卡盘夹持管材，如下图8所示：切割长度过半时，随着第 一尾卡203和第二尾卡205前移，进料段的管材支撑辊206逐步下落，出料段207的管材支撑辊206逐步升起，如下图9所示；当切割到最后一段时，启动切割头避让功能，第一尾卡203松开管材并后移，第二尾卡205带动管材后移一段距离，切割头同步向后移动，对管材尾端进行加工，如下图10所示：切割完成后，第二尾卡205拖动整根管材前移至下料架3处。
