Description
本发明属于轴承钢球坯料热处理领域，具体涉及一种轴承钢球专用连续热处理滚筒式生产线，同时还涉及一种轴承钢球坯料的热处理工艺。
随着钢球坯料制造工艺的改进及设备的研发更新，现阶段工艺流程如下：原材料(棒料)-冷镦-光球-热处理-硬磨-初研-精研-超精研-光学外观-清洗防锈-成品检验-包装。其中，冷镦是通过钢球坯料冷镦机将棒状材料加工为毛坯；光球阶段用于统一冷镦阶段后的尺寸公差，磨削掉球坯的环带和两极，此阶段基本成球形；热处理过程用来改变球坯的内部组织结构，提高钢球坯料的强度和使用寿命；硬磨过程主要用来提高钢球坯料的尺寸精度；研磨过程提高表面精度，然后通过表面检测装置分选后，完成加工。
同时，在上述热处理过程中所采用的加热炉为滚筒炉，由于其滚筒是一个八角形的炉罐，因此，也称为八角滚筒炉，然而，滚筒式电阻炉是周期作业式电阻炉，主要供轴承钢球、滚柱及其它小型标准件的气体渗碳、碳氮和光洁淬火等热处理加热之用，因此，其存在以下技术缺陷：
1)、由于是周期作业(也就是一批次处理完成后，再下一批进行处理)，导致钢球无法进行连续性生产加工，降低钢球成型效率，产量小；
2)、热处理质量不稳定，钢球的内部组织存在很大的差异，因此，合格率非常的低，致使钢球制造成本较高。
然后，在对钢球坯料进入淬火后，需要进行清洗去油，然后再经过油水分离器油水分离，最后将钢球坯料送入回火炉进行回火处理。然而，上述的清洗过程存在以下不足：
1、在油槽和清洗机出料端部，难免存在一些残留的油和水，由于微小的钢球坯料重量很轻，容易和残留的水和油粘结在一起，产生粘球和混球现象，给钢球坯料的连续生产带来不便；
2、常温的清洗液很难将钢球坯料表面的油脂去除(原理和冷水洗碗相同)。
发明内容
本发明所要解决的技术问题是克服现有技术的不足，提供一种全新的轴承钢球专用连续热处理滚筒式生产线。
同时，本发明还提供一种轴承钢球坯料的热处理工艺。
为解决以上技术问题，本发明采取如下技术方案：

优选地，在炉体的一端部并排设有两个绕自身轴心线转动的承载滚轮，滚筒自一端部自由的架设两个承载滚轮上，驱动组件设置在滚筒的另一端部。这样设置的好处，非常省力的实现滚筒的自转驱动，降低能耗，同时，钢球的翻滚力度相对均匀，更有利于钢球均匀的加热。
根据本发明的一个具体实施和优选方面，螺旋进料器包括能够随着滚筒同步转动地设置在炉体进料端部且伸入滚筒内部的器本体、与器本体对接且能够逐批次且定量的将钢球向器本体传送的传送机构。
优选地，器本体包括第一进料筒和第二进料筒，其中第一进料筒与所述传送机构出料端部连通，且在所述的第一进料筒内部设有能够与所述螺旋导流件相连通的螺旋形进料通道，当所述第一进料筒转动至所述螺旋形进料通道与所述螺旋导流件连通位置时，钢球自所述螺旋形进料通道落入所述滚筒内的螺旋导流件中。在此，通过螺旋形进料通道的设置，减少滚筒内热气和保护气氛的外泄，节约能耗，降低钢球热处理成本。
具体的，在螺旋形进料通道上开设缺口，当第一进料筒旋转至缺口朝下时，钢球自动落至滚筒内的螺旋导流件中。
优选地，第一进料筒自炉体进料端部向第二进料筒呈内径逐渐变大的锥台状，第二进料筒自第一进料筒远离炉体进料的端部水平向滚筒内部延伸设置，且第二进料筒的内部充满有保温隔热层。

虽然，这种利用中途仓进行批次钢球的供料是本领域的常用手段，但是在本申请中，其具有一个非常意想不到的技术效果，那就是：进一步结合螺旋形进料通道，彻底杜绝热气和保护气氛的外泄，节约能耗，进而大大降低钢球热处理成本。因此，所带的技术效果是十分显著的。
具体的，第二通道门自一侧部绕着水平方向翻转地设置在中途仓的出料口，传送通道出料端部伸入器本体内部。

与此同时，上述的加热炉还包括设置在炉体进料端部的安全阀组件和设置在炉体出料端部的气氛保护组件、连通在炉体出料端部的下料通道、以及设置在下料通道内的油帘。
至于安全阀组件，在本领域而言，一旦发生爆炸，可迅速将爆炸产生的压力外泄，确保设备安全。
至于气氛保护组件，其形成的保护气氛为氮气和丙烷裂解气，使滚筒内一定的碳势，确保轴承钢球不脱碳。
至于油帘，其一方面由两道通道门和螺旋形进料通道的配合，使得钢球在进出料的过程中不会产生热气和保护气体的外泄，降低热处理成本；另一方面防止钢球淬火时产生的油蒸汽进入炉体内，这样一来，可以杜绝炉膛的积碳或腐蚀，同时也确保钢球的品质。
优选地，第一震荡器和第二震荡器结构相同，均包括设置在钢球淬火系统出料端部和传送系统出料端部的震荡电机、与钢球淬火系统出料端部和传送系统出料端部对接且将钢球导向清洗槽和回火炉的通道。同时，震荡器处于本技术领域的常用产品，申请人直接外购的，在此不对其具体的结构和原理进行阐述。
根据本发明的一个具体实施和优选方面，传送系统包括环形传送网带、设置在环形传送网带上的多个分隔组件、用于驱动环形传送网带转动的驱动组件，其中每相邻的两个分隔组件之间形成一个钢球存放区，清洗槽出料端部与回火炉进料端部之间通过多个钢球存放区相连通。环形传送带的运动在本领域而言，属于常规手段，因此，对驱动的方式可以采用常用的链轮或带轮等等。
优选地，分隔组件包括沿着环形传送网带宽度方向延伸且定位在环形传送网带上表面的定位板、定位在定位板上的分隔板、设置在分隔板两端部的端板、以及用于将位于同侧两个端板相活动连接的封板，其中相邻的两块分隔板；位于相邻两个分隔板之间的端板、封板和定位板；以及环形传送网带上表面形成 钢球存放区。

根据本发明又一个具体实施和优选方面，传送系统还包括定位在提升段上方且对经过的每一个钢球存放区内钢球进行风干的风干组件。
优选地，风干组件包括定位架、风机、以及设置在风机出风口的导风嘴，其中导风嘴包括形成自上而下且自两侧向中部逐渐变窄的嘴本体、自嘴本体上部与风机出风口对接的接头，其中嘴本体沿着环形传送网带宽度方向延伸。
具体的，嘴本体的出风口宽度为钢球存放区宽度的1/10～1/2。
本发明的另一技术方案是：一种轴承钢球坯料的热处理工艺，其采用上述的热处理设备对钢球坯料进行热处理，其具体步骤如下：
1)、由1#上料机将钢球坯料定量且按批次进行上料，然后送入烘干装置中进行预热和烘干；
2)、再由2#上料机将步骤1)中烘干的钢球坯料送入滚筒式加热炉，其中所述的2#上料机的结构与1#上料机的结构相同；
3)、在滚筒的自转和外周加热的前提下，钢球坯料随之翻滚，并在螺旋导流件导向下向出料端部传送，完成加热处理；
4)、自滚筒的出料端部落入淬火系统的淬火油槽中进行淬火处理；
5)、完成淬火处理后的钢球坯料在第一震荡器的震荡下落入清洗机的清洗槽中进行清洗，以去除钢球表面的油脂，其中清洗液的温度控制在45±5℃，然后由油水分离器将油和清洗液分离，并将清洗液循环至清洗槽中进行清洗，待清洗完成后，通过环形传送带将钢球料坯向回火炉传送，并在传送过程中通过风干组件将钢球料进行烘干；
6)、烘干后的钢球坯料在第二震荡器的震荡下传送至回火炉，然后在回火 炉中进行回火处理，最后自回火炉的出料端部排出，完成钢球配料的热处理过程。
由于以上技术方案的实施，本发明与现有技术相比具有如下优点：
本发明一方面在满足连续性生产的前提下，钢球配料在翻滚中进行加热，并由进料端部向出料端部传送，使得钢球加热更加均匀，从而提高钢球热处理的品质；另一方面通过震荡器的震荡方式，杜绝粘球和混球现象的发生，同时通过加热后清洗液更容易将钢球表面的油脂去除，提高清洗效果，此外，产量明显增加，而且钢球的内部组织存在差异较小，质量稳定。

2、通过震荡器e3将钢球从料斗e2里震荡输送至计重机构e4的收集槽e41里。
3、当钢球重量达到设定值时，计重机构e4平衡，触发接近开关，平衡感应器接收到平衡信息并给PLC控制器发信号。
4、PLC控制器向震荡器e3下达停机指令，然后通过气缸e6将收集槽e41出料口的封门e7打开，将钢球输送至提升机e5的上升料斗里，待钢球收集槽e41卸载完毕后，气缸e6再将收集槽e41的封门e7关闭，进而完成钢球的一次定量供料。

结合图6所示，在炉体1的左端部并排设有两个绕自身轴心线转动的承载滚轮a，承载滚轮a的轴心线与滚筒2的轴心线平行。
滚筒2自左端部自由的架设两个承载滚轮a上，驱动组件5设置在滚筒2的右端部。这样设置的好处，非常省力的实现滚筒的自转驱动，降低能耗，同时，钢球的翻滚力度相对均匀，更有利于钢球均匀的加热。
至于，驱动组件5的结构，结合图6，该驱动组件5为常规的链轮传动机构，属于本领域的常识，在此不对其进行详细描述。
本例中，进料端部10位于炉体1的左端部，且通过螺旋进料器b将钢球送向螺旋导流件3的进料端，出料端部11位于炉体1的右端部且与螺旋导流件3的出料端部连通。

至于安全阀组件6，在本领域而言，一旦发生爆炸，可迅速将爆炸产生的压力外泄，确保设备安全。
至于气氛保护组件7，其形成的保护气氛为氮气和丙烷裂解气，使滚筒2内一定的碳势，确保轴承钢球不脱碳。
至于油帘9，其一方面由两道通道门和螺旋形进料通道的配合，使得钢球在进出料的过程中不会产生热气和保护气体的外泄，降低热处理成本；另一方面防止钢球淬火时产生的油蒸汽进入炉体内，这样一来，可以杜绝炉膛的积碳或 腐蚀，同时也确保钢球的品质。
采用本例中滚筒式加热炉，其具有以下优势：
1、本实施例能够在钢球翻滚过程中实现钢球在加热炉内传递，使得钢球加热更加均匀，从而提高钢球热处理的品质；
2、通过两道通道门、螺旋形进料通道、及油帘的设置，使得钢球在进出料的过程中不会产生热气和保护气体的外泄，降低热处理成本；
3、在安全阀组件的设置下，一旦发生爆炸，可迅速将爆炸产生的压力外泄，确保设备安全；
4、在保护气氛保护下，使滚筒内一定的碳势，确保轴承钢球不脱碳。
5、在定量且批次的实现钢球供料的前提下，能够实现钢球热处理过程属于连续性，并非现有八角滚筒炉所公开的周期性，因此，其产能方面有着显著性的提高，而且质量也相对稳定。
至于，淬火系统E，为常规设置，具体参见图8所示，其采用的传送系统和清洗机F的传送系统相同。
参见图9至图11，本例中，用于轴承钢球热处理的清洗机F，其包括机架F1、与钢球淬火系统出料端部对接的清洗槽F2、油水分离器F3、用于将分离后的水循环至清洗槽F2的循环系统F4、用于将钢球自清洗槽F2向回火炉传送的传送系统F5、分别设置在钢球淬火系统出料端部和传送系统出料端部处的第一震荡器F6和第二震荡器F7、设置在清洗槽F2内用于对清洗液进行加热的加热器F8、以及温控器，其中温控器将位于清洗槽F2内清洗液温度下限控制在45℃，当清洗液的稳定低于45℃时，加热器F8自动加热。

结合附图12所示，分隔组件51包括沿着环形传送网带50宽度方向延伸且定位在环形传送网带50上表面的定位板510、定位在定位板510上的分隔板511、设置在分隔板511两端部的端板512、以及用于将位于同侧两个端板512相活动连接的封板513，其中相邻的两块分隔板511；位于相邻两个分隔板之间的端板512、封板513和定位板510；以及环形传送网带50上表面形成钢球存放区Q。
分隔板511垂直于定位板510设置，且相邻的两个分隔板511之间相互平行设置。
具体的，端板512外侧面、封板513内侧面、以及环形传送网带50的端面三者齐平设置。便于形成钢球存放区Q，同时，也增强了网带的强度。
本例中，环形传送网带50包括位于清洗槽F2下方水平传动钢球的水平段50a、自水平段50a的端部向上倾斜设置的提升段50b，其中水平段50a和提升段50b连接处呈弧形过度。

3、在便于形成钢球存放区的前提下，增强网带的强度；
4、通过风干组件的设置，使用钢球进入回火炉之前处于干燥状态，大大降低粘球和混球的机率。
然后，参见图11，回火炉G，其结构与上述的滚筒式加热炉D相似。
具体的，火炉G也为滚筒式，其包括回火炉体G1、内部具有螺旋导流片的回火滚筒G2、设置在回火滚筒G2进料端部与清洗机F出料端部对接的进料器G3、驱动回火滚筒G2自转的驱动单元G4、位于回火滚筒G2底部的加热器G5、以及在回火滚筒G2外周和炉体G2内壁之间形成环流的循环风机G6。

综上所述，本实施例涉及轴承钢球坯料的热处理工艺，其具体步骤如下：
1)、由1#上料机将钢球坯料定量且按批次进行上料，然后送入烘干装置中进行预热和烘干；
2)、再由2#上料机将步骤1)中烘干的钢球坯料送入滚筒式加热炉，其中所述的2#上料机的结构与1#上料机的结构相同；

5)、完成淬火处理后的钢球坯料在第一震荡器的震荡下落入清洗机的清洗槽中进行清洗，以去除钢球表面的油脂，其中清洗液的温度控制在45±5℃，然后由油水分离器将油和清洗液分离，并将清洗液循环至清洗槽中进行清洗，待清洗完成后，通过环形传送带将钢球料坯向回火炉传送，并在传送过程中通过风干组件将钢球料进行烘干；
6)、烘干后的钢球坯料在第二震荡器的震荡下传送至回火炉，然后在回火炉中进行回火处理，最后自回火炉的出料端部排出，完成钢球配料的热处理过程。
