实施例一Embodiment 1
本发明实施例提供一种带钢连续生产线上的带钢切割方法，包括如下步骤：An embodiment of the present invention provides a strip cutting method on a strip continuous production line, which includes the following steps:
在带钢运行通道上方布置切割头31； Arrange the cutting head 31 above the strip running channel;
设计切割头运行路径，使切割头31在带钢长度方向上保持与带钢随动，并且在带钢宽度方向上相对于带钢作横移切割运动；Design the running path of the cutting head so that the cutting head 31 keeps following the strip in the length direction of the strip and performs lateral cutting motion relative to the strip in the width direction of the strip;
当带钢运行到设定位置时，所述切割头31按所设计的切割头运行路径活动，对带钢进行切割。When the strip moves to the set position, the cutting head 31 moves according to the designed cutting head running path to cut the strip.
其中，可以采用热切割方式或水切割方式，热切割方式优选为采用激光切割方式，相应地，所述切割头31为激光切割头；对于水切割方式，上述切割头31对应地为水切割头/水刀。Among them, the thermal cutting method or the water cutting method can be used. The thermal cutting method is preferably the laser cutting method. Accordingly, the cutting head 31 is a laser cutting head; for the water cutting method, the cutting head 31 is correspondingly a water cutting head. /waterjet.
显然地，上述切割头31需要能够移动，相应地，所述切割头31配置有切割头驱动机构，所述切割头驱动机构具有驱动所述切割头31在带钢运行通道长度方向上运动的第一驱动行程以及驱动所述切割头31在带钢运行通道宽度方向上运动的第二驱动行程。在其中一个实施例中，如图1，采用龙门式切割机，具体包括：Obviously, the above-mentioned cutting head 31 needs to be able to move. Correspondingly, the cutting head 31 is configured with a cutting head driving mechanism. The cutting head driving mechanism has a third element that drives the cutting head 31 to move in the length direction of the strip running channel. A driving stroke and a second driving stroke driving the cutting head 31 to move in the width direction of the strip running channel. In one embodiment, as shown in Figure 1, a gantry cutting machine is used, which specifically includes:
机床主机部分：包括龙门架33和活动座，龙门架33可以沿带钢运行通道长度方向滑动，实现切割头31在X向的运动，活动座能在龙门架33上横移，实现切割头31在Y向的运动，进一步还可设置活动座能相对于龙门架33升降，实现切割头31在Z向的运动，可以辅助聚焦，提高切割头31的聚焦效率和聚焦精度。龙门架33的驱动以及活动座的驱动优选为采用伺服电机，能按照控制程序正确而精准的进行驱动；激光器32即安装在上述活动座上，激光器32发出的激光由切割头31出射至带钢表面，实现带钢切割操作；Machine tool host part: including the gantry 33 and the movable seat. The gantry 33 can slide along the length of the strip running channel to realize the movement of the cutting head 31 in the X direction. The movable seat can move laterally on the gantry 33 to realize the cutting head 31 For movement in the Y direction, a movable seat can be further configured to move up and down relative to the gantry 33 to realize movement of the cutting head 31 in the Z direction, which can assist focusing and improve the focusing efficiency and focusing accuracy of the cutting head 31 . The drive of the gantry 33 and the movable seat are preferably driven by servo motors, which can be driven correctly and accurately according to the control program; the laser 32 is installed on the above-mentioned movable seat, and the laser emitted by the laser 32 is emitted from the cutting head 31 to the strip. Surface to realize strip cutting operation;
数控***：控制机床主机实现切割头31的X向、Y向、Z向运动，同时也控制激光器32的输出功率。CNC system: controls the machine tool host to realize the X-, Y-, and Z-direction movements of the cutting head 31, and also controls the output power of the laser 32.
进一步地，上述切割机还包括抽风除尘机构，将加工时产生的烟尘和粉尘抽除并进行除尘处理，使废气排放符合环保要求。 Furthermore, the above-mentioned cutting machine also includes an exhaust and dust removal mechanism to extract smoke and dust generated during processing and perform dust removal treatment so that the exhaust gas emissions meet environmental protection requirements.
进一步地，在带钢输送通道下方还设有废料收集单元，该废料收集单元可配置排渣设备，便于将收集的废料及时排出。Furthermore, there is a waste collection unit under the strip conveying channel. The waste collection unit can be equipped with a slag discharge equipment to facilitate the timely discharge of the collected waste.
如图3，由于切割头31同时具有带钢长度方向上的运动和带钢宽度方向上的运动，呈现出的切割头运行路径是相对于带钢长度方向具有一夹角的斜向运行路径。As shown in Figure 3, since the cutting head 31 has both movement in the length direction of the strip and movement in the width direction of the strip, the running path of the cutting head is an oblique running path with an angle relative to the length direction of the strip.
其中，上述切割头运行路径的设计考虑的因素主要包括带钢规格、带钢运行速度和切割时间等，由带钢规格可以确定切割头31的起始运行位置，带钢运行速度则主要决定切割头31的X向移动速度，切割时间要求结合带钢规格则能确定切割头31的Y向移动速度。针对不同的工况，切割头运行路径会有差异，但所有切割头运行路径会在切割头31的两条边界运行路径范围之内(如图3所示)。Among them, the factors considered in the design of the above-mentioned cutting head running path mainly include strip steel specifications, strip running speed and cutting time. The starting running position of the cutting head 31 can be determined by the strip steel specifications, and the strip running speed mainly determines the cutting speed. The X-direction movement speed of the head 31, the cutting time requirement combined with the strip steel specifications can determine the Y-direction movement speed of the cutting head 31. For different working conditions, the cutting head running paths will be different, but all cutting head running paths will be within the range of the two boundary running paths of the cutting head 31 (as shown in Figure 3).
可以理解地，“使切割头31在带钢长度方向上保持与带钢随动”，即需要使切割头31的X向移动速度与带钢运行速度保持一致。带钢运行速度是由带钢输送装置1所控制的，因此可使切割头驱动机构与带钢输送装置1联锁控制，以保证上述随动要求，避免造成带钢废料。It can be understood that "keeping the cutting head 31 following the strip in the length direction of the strip" means that the X-direction moving speed of the cutting head 31 needs to be consistent with the running speed of the strip. The strip running speed is controlled by the strip conveying device 1, so the cutting head driving mechanism and the strip conveying device 1 can be interlocked and controlled to ensure the above following requirements and avoid strip scrap.
基于上述方法，本实施例可以实现带钢连续生产线上的带钢在线连续切割操作，无需停剪或飞剪，保证带钢生产的可靠性和顺畅性，尤其适用于高强钢板的在线连续切割作业。Based on the above method, this embodiment can realize the online continuous cutting operation of strip steel on the strip steel continuous production line without stopping or flying shearing, ensuring the reliability and smoothness of strip steel production, and is especially suitable for the online continuous cutting operation of high-strength steel plates. .
进一步优化上述方法，如图3，根据不同工况下的切割头运行路径所限定的切割头运行范围，将带钢运行通道划分为切割区域101和非切割区域102，对切割区域101内的带钢输送装置1进行保护设计。基于该设计，能较好地保护带钢输送装置1，对切割区域101和非切割区域102的带钢输送装置1进行匹配性设计，可以有效地降低设备成本和维护成本。 To further optimize the above method, as shown in Figure 3, according to the cutting head operating range limited by the cutting head operating path under different working conditions, the strip running channel is divided into a cutting area 101 and a non-cutting area 102. The strip in the cutting area 101 is Steel conveyor 1 is designed for protection. Based on this design, the strip conveying device 1 can be better protected, and the matching design of the strip conveying device 1 in the cutting area 101 and the non-cutting area 102 can effectively reduce equipment costs and maintenance costs.
在其中一个实施例中，在切割区域101，带钢输送装置1的适于与带钢接触的传送表面采用耐激光辐照的材料制成，例如在传送表面镀铜或形成其他耐激光辐照的材料层。上述结构能较好地保护带钢输送装置1，避免激光穿过带钢而烧蚀带钢输送装置1，以及避免带钢输送装置1出现表面缺陷而影响带钢表面质量。In one embodiment, in the cutting area 101, the conveying surface of the strip conveying device 1 that is suitable for contact with the strip is made of a material that is resistant to laser radiation, for example, the conveying surface is copper-plated or otherwise formed to be resistant to laser radiation. material layer. The above structure can better protect the strip conveying device 1, prevent the laser from passing through the strip and ablating the strip conveying device 1, and prevent surface defects of the strip conveying device 1 from affecting the surface quality of the strip.
在其中一个实施例中，如图2和图3，在切割区域101，带钢输送装置1包括沿带钢运行通道长度方向依次排列的多个输送单元，每个输送单元包括安装在传动辊轴11上的至少一个第一输送滚盘12；传动辊轴11上安装有多个第一输送滚盘12时，各第一输送滚盘12在该传动辊轴11上依次间隔排列。In one embodiment, as shown in Figures 2 and 3, in the cutting area 101, the strip conveying device 1 includes a plurality of conveying units arranged sequentially along the length direction of the strip running channel, each conveying unit includes a drive roller installed on At least one first conveying roller 12 on the transmission roller 11; when multiple first conveying rollers 12 are installed on the transmission roller 11, each first transmission roller 12 is arranged at intervals on the transmission roller 11.
将各第一输送滚盘12间隔布置，可以减少可能出现在切割介质影响范围(例如激光辐照范围)内的带钢输送设备，从而相应地减少带钢切割过程中的带钢输送装置1的损伤。另外，采用第一输送滚盘12作为输送设备，在保证对带钢的可靠输送要求的前提下，第一输送滚盘12的更换也非常方便，将标准化生产的新的第一输送滚盘12替换出现缺陷的第一输送滚盘12即可，避免传统的辊式输送设备需要更换整个输送辊的情况，可以降低维护成本；相应地，第一输送滚盘12可拆卸地固定安装在传动辊轴11上。Arranging the first conveying rollers 12 at intervals can reduce the number of strip conveying equipment that may appear within the influence range of the cutting medium (such as the laser irradiation range), thereby correspondingly reducing the number of strip conveying devices 1 during the strip cutting process. damage. In addition, the first conveying roller 12 is used as the conveying equipment. On the premise of ensuring reliable conveying requirements for strip steel, the replacement of the first conveying roller 12 is also very convenient. The new first conveying roller 12 will be standardized and produced. Just replace the defective first conveying roller 12, which avoids the need to replace the entire conveying roller in traditional roller conveying equipment, which can reduce maintenance costs; accordingly, the first conveying roller 12 is detachably fixed and installed on the transmission roller. on axis 11.
在上述“传送表面采用耐激光辐照的材料制成”的方案中，相应地，第一输送滚盘12的外缘表面采用耐激光辐照的材料制成即可，也能显著地减少所需的耐激光辐照材料耗量。In the above solution of "the transmission surface is made of materials resistant to laser irradiation", correspondingly, the outer edge surface of the first conveying roller 12 only needs to be made of materials resistant to laser irradiation, which can also significantly reduce the cost. The required consumption of laser radiation resistant materials.
在其中一个实施例中，如图2和图3，上述第一输送滚盘12中，其用于与带钢接触的轮缘环的截面呈纺锤形，也即该轮缘环从内环向外环方向呈渐缩结构，基于该结构，可进一步减小第一输送滚盘12与带钢的接触范围，也即减小上述传送表面的面积，从而减少切割介质对带钢输送设备所造成的损伤。 In one embodiment, as shown in Figures 2 and 3, in the above-mentioned first conveying roller 12, the rim ring used to contact the strip has a spindle-shaped cross-section, that is, the rim ring extends from the inner ring to the steel strip. The direction of the outer ring has a tapered structure. Based on this structure, the contact range between the first conveying roller 12 and the strip can be further reduced, that is, the area of the above-mentioned conveying surface can be reduced, thereby reducing the impact of the cutting medium on the strip conveying equipment. of damage.

Based on the above structure, the maintenance of the first conveying roller 12 can be facilitated, that is, only the rim ring needs to be replaced, which can effectively reduce maintenance costs.
进一步地，如图2，在切割区域101内，裸露的传动辊轴11上(即未套装第一输送滚盘12的辊轴轴段上)套设有保护管15，防止切割过程中切割介质损伤该传动辊轴11，进一步降低维护成本。Further, as shown in Figure 2, in the cutting area 101, a protective tube 15 is set on the exposed transmission roller 11 (that is, the roller shaft section that is not covered with the first conveying roller 12) to prevent cutting of the medium during the cutting process. Damage to the transmission roller 11 further reduces maintenance costs.
进一步优选地，如图2和图3，所述传动辊轴11延伸至非切割区域102的轴段上安装有多个第二输送滚盘13。第二输送滚盘13的外周面优选为是圆柱环面，与带钢具有相对较大的接触面积，保证对带钢的可靠输送，同时可提高传动辊轴11的各个轴段受力均匀性，避免传动辊轴11发生扭转变形等缺陷。Further preferably, as shown in FIGS. 2 and 3 , a plurality of second conveying rollers 13 are installed on the shaft section of the transmission roller shaft 11 extending to the non-cutting area 102 .
