Description

砂轮切割设备及切割方法 技术领域
本发明涉及切割技术，具体的讲是一种砂轮切割设备及方法。
背景技术
母合金是经过精炼后供重熔浇注用的材料，通常为棒料，目前常用的母合金有高温合金母合金、双相钢母合金、不锈钢母合金和耐热钢母合金等。由于母合金使用者主要为铸件生产者，对母合金的成分要按照要求进行严格定制，同时，在对母合金的切割中，对切割的重量也有严格要求。
在母合金的浇注凝固过程中，当母合金的金属液浇注到模具中时，由于模具的温度低于金属液温度，接近母合金模具表面的金属液迅速凝固、冷却，在凝固过程中，母合金棒材从中间向外收缩，极易在母合金棒材的中心位置出现缩孔，砂轮经过缩孔，极易产生污染，影响精铸质量。
现有技术的母合金棒材切割方式中，切割棒料方式为定尺切割，以固定的定尺长度切割母合金棒材，现有技术中，即使是同规格的母合金棒料在表面打磨或扒皮后，外径会也有±2mm的误差，若只考虑切割长度，就会造成重量误差，存在的误差容易造成母合金材料的浪费或铸造零件的补缩不充分。同时，现有技术中，金属材料的切割，历来是重体力、高污染、多事故、自动化程度低的工种，需要一种更高效、更精确的切割方案，以解决现有技术中存在的诸多问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参照后文的说明和附图，详细公开了本发明的特定实施方式，指明了本发明的原理可以被采用的方式。应该理解，本发明的实施方式在范围上并不因而受到限制。在所附权利要求的精神和条款的范围内，本发明的实施方式包括许多改变、修改和等同。
针对一种实施方式描述和/或示出的特征可以以相同或类似的方式在一个或更多个其它实施方式中使用，与其它实施方式中的特征相组合，或替代其它实施方式中的特征。
应该强调，术语“包括/包含”在本文使用时指特征、整件、步骤或组件的存在，但并不排除一个或更多个其它特征、整件、步骤或组件的存在或附加。
本发明实施例提供一种砂轮切割设备，砂轮切割设备包括：第一激光测距传感器、主控装置以及砂轮片，第一激光测距传感器与主控装置通信连接；其中，
所述的激光测距传感器，用于采集棒料的外径；
所述的主控装置，用于根据采集的棒料的外径、棒料的材料密度以及设置的料段重量确定当前预切割的料段长度；
所述的主控装置根据确定的料段长度控制砂轮片对棒料进行旋切。
母合金的切割下料是根据后面精铸或制粉工艺所需重量而定，现有技术中普遍采取的方式是定长切割，即视棒材外径一定，结合母合金材料密度，设定下料长度来操作，对同一材 料采用定长切割。但在实际应用时，同炉批的母合金棒往往因锭模尺寸和消除铸造表面缺陷的加工而不一致，与标注外径存在±2mm误差，存在的外径误差会导致各切割段的重量不满足后面精铸或制粉工艺所需重量要求，造成浪费或补缩不足。
本发明的砂轮切割设备提供一种定重切割方式，当被切割棒料被锁紧保持稳定时，利用激光测距仪(激光测距传感器)测量当前被切割棒料的外径，根据测得的外径数据、棒料的材料密度数据以及所需要的重量数据，确定当前棒料的切割长度。即利用下式确定切割长度：
L＝G/[ρ*(d/2) 2*π]
其中：L为确定的切割长度；d为测距传感器采集测得的外径；G为用户设置的切割后的料段重量，即所需要的重量；ρ棒料的材料密度；π圆周率。
因母合金棒往往会有很多修磨点，为避免偏差，本发明一实施方式中，通过转动装置带动棒料转动，测得一组外径数据，将测得的外径数据取平均值得到外径d，以使精度更高。
如图1所示，为本发明一实施例提供的切割设备的示意图，棒料103被卡盘102锁紧保持稳定时，上部激光测距仪101测量棒料103外径，主控装置(图中未标示)根据棒料的外径、预存储的棒料的材料密度以及设置的料段重量确定切割长度，砂轮切割设备根据确定的切割长度切割棒料。
本发明一实施例中，对母合金棒料进行切割时，考虑到母合金棒去除氧化皮的方式有两种，车床扒皮的棒料圆度较好，一般转动45°即可，而辊磨的棒料有时出现微微椭圆，测量外径时可以采用转动90°。
本实施例中的砂轮切割设备，还包括自动上料机构，如图2所示，为本实施例提供的上料结构的示意图，本实施例的上料机构包括：翻转臂201，料架平台202以及油缸203，料架平台202用于放置待切割的棒料，通过油缸203控制翻转臂201提取棒料103送至切割设备进行处理。图3所示，为本实施例中自动上料机构的侧视图。
如图4所示，本实施例中，将多根棒料一次放在料架平台上，本实施例的平台面与水平面有5度的倾斜角(本发明实施例中的倾斜角度并不以此为限)，料棒靠重力滚动到翻转臂前端，通过油缸驱动翻转臂的转动，将单根棒料自动放置送料工位。
如图5所示，棒料放入料架后，通过控制翻转臂201升降，送入一根待切割棒料，通过挡料块205阻挡料架平台202上的其它棒料滚落。砂轮切割设备的推杆301推棒料进入前端的自动卡盘(图中未标示)，卡盘锁紧料棒并旋转45°或90°。
如图6所示，为本实施例的翻转臂的侧视图，翻转臂上设有L型止退连杆204、位于两端的V型结构，本实施例中，通过L型止退连杆204和V型结构207防止棒料103到达送料滚轮302时来回滚动，通过V型结构206实现翻转臂翻转时提取一根棒料。
本发明一实施例中，通过激光测距仪检测棒料103外径，如图7所示，本实施例中激光测距仪701设置于卡盘702前部上方，测量棒料103外径，主控装置计算外径平均值，根据预存棒料密度及要下料重量(即料段重量)计算切割长度，主控装置通过控制驱动装置驱动推杆301行程到位后，卡盘702锁紧棒料，砂轮片对棒料进行切割。
本发明一实施例中，切割设备对棒料的切割过程中，通过卡盘旋转棒料进行环状切割，切割至预设中心外径即停止切割，即对棒料进行环形切割在切割至预设深度完成切割，如图8所示，本发明一实施例中通过另一激光测距仪测量棒料的切割深度，本实施例中的测量棒料切割深度的激光测距仪703设置于卡盘702后部的上方，测量砂轮片705对棒料103的切割深度。同时，本发明实施例中，主控装置根据测量得的预留的中心外径，根据预设的算法确定砂轮片损耗数据，在下一次切割中，根据确定的损耗数据补偿砂轮片损耗，以避免由于砂轮片的损耗造成的切割深度不足。
本发明实施例公开的切割设备在对棒料进行切割时，切割至预设中心外径处停止切割，即本发明的切割设备在切割过程中不切断棒料，砂轮片不经过棒料的中心，避免了由于砂轮切割过程中的砂粒、粉尘进入棒料缩孔，造成精铸件因夹杂物报废的问题。为实现切割过程中砂轮片接触不到缩孔，更好的实现上述切割方式，本发明实施例中，切割设备对棒料的切割采用互动旋切并控制切割深度，即切割时同时旋转棒料，进行环形切割。
如上所述，为避免砂轮片经过缩孔造成污染，本发明实施例中采取的是互动旋切，同时，为避免缩孔开放于切割环境，本发明实施例采用整根棒料多刀数不切断方式切割。但是产品在旋转切割时因棒料不直会出现甩动(跳动)，会造成产品甩断或影响砂轮的切割，以及会出现安全事故，因此，本发明实施例的切割设备进一步包括：柔性托举装置，用于对已切割部分棒料提供柔性托举，以免随动旋转过程造成棒料甩断或影响后方砂轮对棒料的切割。柔性托举装置包括：托举支架、V型板、浮动弹簧以及第一液压油缸；如图9所示，托举支架包括：油缸安装板901，上下移动板902，四根导杆903，底板904，所述的油缸安装板901、上下移动板902均安装于四根导杆903，第一液压油缸安装于油缸安装板901，上下移动板902设置于油缸安装板901的下方，第一液压油缸通过顶板911作用于上下移动板902，所述的浮动弹簧设置于顶板911与上下移动板902之间。
本实施例中，油缸安装板901，上下移动板902，导杆903安装于底板904形成上部托举支架，传送棒料的链轮安装于底板904，并穿过上部托举支架。托举支架的油缸安装板上有第 一液压油缸，用于为上下移动板902提供上下移动的动力支持，被切割的棒料放置于链轮907，链轮907用于为棒料提供托举，并在对棒料完成一个料段的切割后，将棒料向下一个处理工位的安全传送。本实施例中托举装置还包括：底板904，横梁905以及立板906，构成链轮支撑平台，用于安装用于传送、托举棒料的链轮907。
如图10所示，切割棒料时，棒料103穿过卡盘702后，棒料前端部分放置于链轮907上，由链轮907输送棒料103。
如图11所示链轮907的链条板9071上设有V型板908，V型板908上安装浮动止拨螺丝909，止拨螺丝909的头部是弹性的，可以各方向转动托住料棒。如图12所示，柔性托举装置在液压油缸910和顶板911之间安装浮动弹簧912，用螺丝连接预留一定的压缩量，链轮907安装于柔性托举装置的底板904上。
如图13所示，在底板904的下方设有第二液压油缸(图中未标示)，第二液压油缸通过立板906安装于底板904的下方，第二液压油缸通过油缸顶板913作用于底板904，顶板913与底板904之间也设有浮动弹簧，下部浮动弹簧在棒料上升时起到缓冲，减少震动，从下方为棒料提供弹性托举。在棒料完成料段切割后，压断棒料形成料段的过程中，液压油缸910向下作用于上下移动板902，底板904下方的液压油缸向上作用于顶板913，通过V型板908夹紧棒料103，为棒料提供柔性托举。
本实施例中，在上下移动板902的下方也安装有V型板908，与链轮907的输送带上的V型板共同作用，防止棒料甩动，本实施例中，柔性托举装置通过上下的浮动弹簧为棒料提供柔性托举，柔性托举装置会和料棒同步运动，使料棒在托举力的状态下稳定切割。
本发明一实施例中，砂轮切割设备还包括：自动卡盘锁紧装置，如图14所示，为本实施例中自动卡盘锁紧装置的剖视图，本实施例中，自动卡盘锁紧装置包括：机械卡盘1301，液压马达1302，升降机构1303，卡盘钥匙1306以及升降油缸1304，机械卡盘1301安装固定于卡盘安装支架1305上，液压马达1302，升降机构1303以及升降油缸1304安装于卡盘安装支架1305的下方，液压马达控制卡盘钥匙1306的旋转，通过升降油缸1304控制升降机构的升降，本实施例中，通过升降油缸1304控制升降机构1303的升降以将卡盘钥匙1306插入机械卡盘1301的钥匙孔，然后通过液压马达控制卡盘钥匙1306在卡盘钥匙孔内的旋转，以控制卡盘锁紧或放松，实现机械卡盘的自动锁紧、放松，解决了现有技术中，机械卡盘的使用中，由人工锁紧/放松，提高了机械卡盘的使用效率，同时降低工人的劳动强度，同时由计算机设备控制液压马达控制机械卡盘的锁紧，保证了卡盘的锁紧力。图15本实施例中提供的自动卡盘锁紧机构的正视图，图16为本实施例中，自动卡盘锁紧机构的关于机械卡盘的局部示 意图，卡盘钥匙1306穿过卡盘安装支架1305的安装板，通过控制卡盘旋转，卡盘钥匙孔1307对准卡盘钥匙1306，通过卡盘钥匙1306控制机械卡盘1301的锁紧/放松。
本发明实施例中，采用机械卡盘1301代替现有技术中常用的液压卡盘，解决了液压卡盘内孔较小的问题，使得本实施例中的切割设备满足更多的切割需求，应用更广泛。
本实施例中，卡盘的锁紧需要两个动作来完成，一个是卡盘钥匙的旋转运动，二是卡盘钥匙要脱离或进入卡盘孔。为了实现这两个动作，将卡盘钥匙要和旋转机构同升降机构要有机的结合。本发明实施例中，卡盘自动锁紧机构设计时采用液压马达和升降油缸有机的结合，将液压马达的扭力转换成压力来控制卡盘锁紧的程度，通过压力传感器控制液压马达来实现卡盘锁紧的目的。升降油缸的动作将卡盘钥匙与卡盘脱离或进入。
另外，因为本发明上述实施例中的自动卡盘锁紧机构采用机械卡盘代替现有技术中常用的液压卡盘固定棒料，因此，本发明又一实施例中，能够使得切割设备具有两套卡盘自动锁紧机构，通过两个机械卡盘在切割过程中更好的固定棒料，为被切割棒料提供更稳定的支撑，如图17所示，为安装两个机械卡盘1301的切割设备的局部示意图。
本发明实施例中，棒料从卡盘中穿过完成料段切割后，由链轮进一步将棒料传送至下一操作工位进行压断，本实施例中的切割设备，其在进行压断操作的工位还设有浮动滚轮送料机构，通过浮动滚轮送料机构，棒料压断时即要保证滚轮的安全，又要有足够的回弹力，且要保证长时间运行的稳定性。解决了现有的滚轮送料机构是通过气缸升降，成本高，工件定位不准确，本实施例中的滚轮送料机构保证产品顺畅移动，压断时保证滚轮及相关机构的安全，且压断位置准确。
如图18所示，为本实施例中的浮动滚轮送料机构的侧视图，其包括：滚轮1801，V型压块1802，以及压缩弹簧1803，通过控制滚轮1801的转动将传送棒料103，V型压块1802用于为棒料103提供稳定的托举，图19和图19A为本实施例中浮动滚轮送料机构的局部示意图，连接板1804和纵向连接板1805构成浮动滚轮送料机构的支撑件，本实施例中连接板1804通过螺丝安装于承载送料机构的底座，本实施例中的浮动滚轮送料机构，将弹簧1803套装于螺丝，为送料机构提供弹性浮动，实现了本实施例中的浮动滚轮送料。
棒料切割完成后，控制装置控制浮动滚轮送料机构将被切割的棒料传送至指定位置，并由加紧装置加紧固定，如图20所示，由夹紧固定装置1901夹紧棒料，然后由压断装置对棒料进行冲压，在切割后的环形切口处将棒料压断。如图18所示，本发明实施例中切割设备具有V型托架1802，控制装置控制浮动滚轮送料机构将被切割的棒料传送至托架1802，并使得切割形成的环形切口位于托架外部，如图21所示，本实施例中的切割设备具有一出料口1902，控制装置控制浮动滚轮送料机构将被切割的棒料传送至出料口1902，并使得切割形成 的环形切口位于送料口外部，以便压断装置冲压棒料103时，在切割设备对棒料切割后形成的环形切口处将棒料压冲断。
另外，本发明实施例公开的砂轮切割设备还具有烟尘风道及颗粒收集装置，将颗粒收集装置设置于棒料进行切割的位置，以收集棒料切割过程中产生的颗粒，如图22所示，本实施例中，颗粒收集装置2201位于切割砂轮片的下方，烟尘风道2202设置于颗粒收集装置2201的上方。
现有技术中，烟尘、颗粒在回收时并没有将其分离处理，烟尘、颗粒一并由烟道排出容易污染环境。本发明提供一种烟气颗粒收集装置，用于采集切割设备切割棒料时产生的烟气及颗粒，烟气颗粒收集装置包括：烟气颗粒集尘箱2201以及烟尘风道2202；烟气颗粒集尘箱2201设置于切割设备的砂轮片与料棒接触点切线方向的下方，采集切割设备产生的颗粒，烟尘风道2202设置于烟气颗粒集尘箱2201与砂轮片之间，并与集尘箱2201相连通，以排出产生的烟尘。
如图22A所示，本发明实施例中，烟气颗粒收集装置还包括：壳体2203，烟气颗粒集尘箱2201通过抽屉结构安装于壳体2203，更加便于烟气颗粒的收集。
本实施例中，烟尘风道2202和颗粒收集装置2201有效的结合，将烟尘风道2202设计到颗粒收集装置2201的上部，因烟尘的密度同颗粒不同，烟尘通过烟尘风道2202排出，颗粒靠自重下沉到颗粒收集装置2201底部，将烟尘、颗粒分层次排放，延长切割设备更换滤筒的周期，降低滤筒的使用成本，方便颗粒的收集。另外，在高温合金的加工中，由于强化元素的稀缺性决定了高温合金废料分牌号、分类的收集更为重要，本发明的烟气颗粒收集装置，利用抽屉式结构集尘箱，同时可将不同牌号颗粒分别收集在不同的集尘箱中，实现了颗粒的分牌号、分类收集，以利于循环利用。
本发明提供的砂轮切割设备，其提高了工作效率降低劳动强度，同时提高产品的品质，并且本实施例中的砂轮切割设备包括的自动上料机构、卡盘锁紧机构、柔性托举机构、烟尘颗粒收集机构等各模块，均可模块化独立设计、组装，通过螺丝等连接部件完成组装，提供一种更便捷、智能化的切割设备。
同时，本发明实施例提供的砂轮切割设备还包括：多个外壳，分别将上述的各机构模块设置于一外壳。图23为本发明一实施方式中的切割设备的整体示意图。

如图28、图29所示，为本实施例中的拉杆253的侧视图、示意图，拉杆的末端具有T型卡扣2531，拉杆通过T型卡扣2531与锥桶的卡扣槽2522相匹配；
拉杆253穿设于主轴，拉杆头部2532固定于主轴的一端，本发明实施例中，拉杆头部通过螺栓固定于主轴的一端。拉杆头部与主轴之间设有至少一个弹簧，在图28、29所示的实施方式中，利用四个螺栓通过螺纹孔2533将拉杆固定于主轴，将螺栓穿设与弹簧，以在拉杆头部与主轴之间弹簧，通过弹簧、拉杆将法兰拉住，保证砂轮片在切割时的稳定性。
锥桶2521从主轴的另一端插入主轴，在主轴内将卡扣槽与拉杆的T型卡扣相连接，以将安装有砂轮片的法兰固定于主轴的另一端。
本发明实施例中，砂轮片与法兰的一侧通过螺纹连接。

同时，本发明实施例还提供一种砂轮切割设备，该砂轮片切割设备具有前述的砂轮片装置，砂轮设备的传动装置通过带动所述砂轮片装置的主轴，以带动所述砂轮旋转切割。
