1)、首先,将钢棒输送至钢棒加热炉内加热,加热后的钢棒输送至剪棒机内剪成多段,然后将每段逐个的输送至粗锻机和精锻机,锻打呈球状;
2)、将锻成型的钢球通过提送装置输送至冷却系统进行冷却,然后将冷却后的钢球输送至二次加热系统内进行再次加热,最后将再次加热的钢球输送至淬火系统和回火系统内进行处理,完成钢球的生产。
然而,在冷却过程中,需要将800℃的钢球降温至200℃,然后将200℃输送至二次加热系统内进行再次加热,因此,在800℃降温至200℃过程中,大部分采用的都是风冷,而且风冷的过程中,耐磨钢球锻造余热直接损耗,这样造成了能源的浪费,同时,风冷所需要的轨道极长,占用空间大。
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,提供一种全新的耐磨钢球锻造余热进行耐磨钢球热处理工艺。
为解决以上技术问题,本发明采取如下技术方案:
一种耐磨钢球锻造余热进行耐磨钢球热处理工艺,该工艺所采用的热移位装置包括冷却区域、设置在耐磨钢球锻造机和冷却区域之间的送料单元、以及自动排球单元,特别是,冷却区域包括具有进料端和出料端的双层料床、设置在所述双层料床内的下层轨道和上层轨道、冷却风机,其中所述进料端和所述出料端位于所述双层料床的同一端部,且所述出料端位于所述进料端的上方,所述的下层轨道具有第一进球端部和第一出球端部,所述上层轨道具有第二进球端部和第二出球端部,所述的第一进球端部与所述进料端连通,所述第二出球端部与所述出料端连通;所述的自动排球单元包括自所述出料端向外延伸的排球轨道、设置在所述第二出球端部和所述排球轨道之间的排球接驳器;所述的热移位装置还包括用于将所述第一出球端部和所述第二进球端部相衔接且能够将耐磨钢球自所述下层轨道提升至上层轨道的钢球提升器;
该工艺包括如下步骤:
1)、将锻造后800±50℃的耐磨钢球通过送料单元向双层料床的进料端逐个地传输;
2)、耐磨钢球自进料端进入下层轨道,并沿着下层轨道向第一出球端部自由滚动,同时由冷却风机对耐磨钢球进行冷却,使得耐磨钢球温度下降至550±10℃;
3)、在钢球提升器的工作下,自第一出球端部传出的耐磨钢球提升至上层轨道的第二进球端部,并沿着上层轨道向第二进球端部自由滚动,冷却风机将下层轨道耐磨钢球的热量向上吹动,且上层轨道分成两段,耐磨钢球自前段向后端滚动,其中前段耐磨钢球温度为350±10℃,后段耐磨钢球温度为200±5℃;
4)、通过排球接驳器逐个的将上层轨道的上耐磨钢球逐个的接驳输送至排球轨道,使得耐磨钢球温度为200±5℃传出双层料床。
优选地,下层轨道和上层轨道均自上而下倾斜设置,其中下层轨道的第一进球端部位于第一出球端部的上方,耐磨钢球自第一进球端部向第一出球端部自由滚动;上层轨道的第二进球端部位于第二出球端部的上方,耐磨钢球自第二进球端部向第二出球端部自由滚动。这样一来,耐磨钢球在下层轨道和上层轨道上均是在自重下自由滚动,无需动力,方便实施,同时也改善耐磨钢球冷却的均匀性。
具体的,下层轨道和上层轨道所形成的倾斜角为1~3°。
根据本发明的一个具体实施和优选方面,双层料床包括并排且连通的第一床体和第二床体,下层轨道包括长度方向一致的第一轨道本体和第二轨道本体、以及设置在第一轨道本体和第二轨道本体之间的第一轨道接驳器;上层轨道包括长度方向一致的第三轨道本体和第四轨道本体、以及设置在第三轨道本体和第四轨道本体之间的第二轨道接驳器。通过两个床体的设置,一方面能够确保耐磨钢球的冷却效果,一般的耐磨钢球进入在第一轨道本体时800℃左右,在第二轨道本体上冷却至550℃左右,在第三轨道本体上温控在350℃左右,在第四轨道本体上温控在200℃左右;另一方面,能够进一步使得结构紧凑,占用空间小。
优选地,第一轨道接驳器和第二轨道接驳器的结构相同,均包括形成有耐 磨钢球取料槽的接驳轮盘、驱动接驳轮盘自转的驱动部件。
具体的,耐磨钢球取料槽只能容纳一个所述耐磨钢球,且接驳轮盘上设有多个所述耐磨钢球取料槽,其中一个处于取球状态时,剩余的所述耐磨钢球取料槽中的一个处卸球状态,其他的耐磨钢球取料槽处于等待取球状态。这样每次取一个耐磨钢球送入下一个轨道本体,进而确保每一个耐磨钢球均匀的实现冷却。
根据本发明的又一个具体实施和优选方面,冷却风机有多个,其中多个冷却风机并排且间隔分布在第一床体和第二床体的底部。这样形成风向上,将余热的热量向上吹,从而对冷却后耐磨钢球进行预设,进而充分利用锻造耐磨钢球的余热。
优选地,第一轨道本体和第二轨道本体位于冷却风机的上方。此时的余热利用率处于最佳状态。
根据本发明的一个具体实施和优选方面,送料单元包括接引轨道、送球轨道、以及将接引轨道和送球轨道相衔接的环形上料器,其中环形上料器包括环形带、绕着环形带周向分布的多个球斗、以及驱动环形带转动的驱动件,每个球斗能够自接引轨道上接引耐磨钢球,并在环形带的转动下,向送球轨道移动并至送球轨道所在位置时,耐磨钢球自球斗自由滚落至送球轨道。采用连续且高效的送料单元能够快速且准确地将耐磨钢球逐个送入双层料床中冷却、以及利用冷却所散发的热量进行预热。
优选地,环形上料器竖直设置,接引轨道位于环形上料器下端部的一侧,送球轨道位于环形上料器上端部的另一侧。
进一步的,送球轨道包括接球料槽、与接球料槽相连通且自上而下倾斜的斜置料槽、以及位于进料端且竖直延伸的供料料槽,送料单元还包括设置在供料料槽的顶升器。
根据本发明的一个具体实施和优选方面,顶升器包括顶面与下层轨道所形成轨道面平行设置的顶升平台、以及驱动顶升平台上下升降的伸缩杆,其中顶面与轨道面齐平时,耐磨钢球自由滚落至轨道面。因为,自送球轨道传输的球速度很快,若不对其进行减速,那么进入下层轨道的速度会更快,不仅存在脱轨的风险,而且进行风冷时间变短,进而存在冷却不均匀的问题。
此外,热移位装置还包括设置在第一出球端部的出球接驳器、设置在第二进球端部的接球轨道,钢球提升器将出球接驳器传出的耐磨钢球提升至接球轨道。
优选地,钢球提升器包括竖直延伸的提升轨道、滑动设置在提升轨道上的提升料斗、驱动提升料斗沿着提升轨道上下移动的驱动器、以及设置在接球轨道上的自动卸球组件,其中提升料斗包括能够上下活动设置在提升轨道上的提升座、绕着水平方向翻转地设置在提升座上的提升斗,自动卸球组件与提升斗配合,在提升座在所对应的自动卸球组件所构成的卸料区内上下运动中驱动提升斗翻转卸料或翻转复位。
优选地,提升斗包括斗底板、围设在斗底板侧边的斗壁板,其中斗壁板和斗底板构成开口朝上的斗腔。
进一步的,斗壁板通过水平设置在转轴转动设置在提升座上。这样方便实施斗腔的翻转和复位动作。
根据本发明的一个具体实施和优选方面,斗腔沿着转轴长度所形成的截面呈直角梯形,其中斗底板构成直角梯形的下底,其上底的长度大于下底的长度,转轴设置在直角梯形斜边上。这样的斗腔,十分方便耐磨钢球的接球,同时也方便实施耐磨钢球的卸球。
根据本发明的又一个具体实施和优选方面,自动卸球组件包括设置在接球轨道一侧的弧形导轨、以及设置在提升斗相对侧的导轮,其中导轮能够在弧形导轨中滑动,当向上抬升时,导轮自弧形导轨的下部向上部移动,并驱使的提升斗水平翻转,位于提升斗内耐磨钢球自由卸载至接球轨道上,当向下复位时,导轮自弧形导轨的上部向下部移动,并驱使的提升斗翻转复位,导轮脱离弧形导轨时,提升斗架设在提升座上。在弧形导轨和导轮的配合下,可在提升座上行的过程中自动翻转卸球,在提升座下行的过程中自动翻转复位。
优选地,导轮对应设置在直角梯形上底和斜边所在的拐角处,且位于提升斗的相对侧。此时所提供的驱动力最佳,便于实施提升斗的翻转。
进一步的,导轮绕着自身轴线方向自由转动地设置在提升斗的相对侧。将摩擦降低,进一步方便实施水平翻转。
根据本发明的又一个具体实施和优选方面,弧形导轨有两条,且对应设置 在接球轨道的相对两侧,导轮对应设有两个,且分别设置在提升斗的相对两侧。这样一来,通过双弧形导轨的设置,使得提升斗的翻转动作更加稳定的实施。
此外,驱动器为移动小车,移动小车在提升轨道上移动,提升座与移动小车相固定连接。
同时,钢球提升器还包括设置在第一出球端部且能够逐个将耐磨钢球传输至与对应位置所述提升斗内的出球接驳器。也就是说,本例中,限定了每次提升只有一个耐磨钢球,避免耐磨钢球之间的碰撞或冷却不均匀。
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:
本发明一方面通过双层料床和上下层轨道的设置,能够充分的利用锻造耐磨钢球的余热对冷却后进入二次加热系统之前的耐磨钢球进行预热,从而杜绝能量的损耗和浪费,降低生产成本;另一方面冷却和预热所用轨道进行上下叠设,进而减小轨道占用空间,结构简单,方便实施。

结合图3所示,下层轨道2和上层轨道3均自上而下倾斜设置,其中下层轨道2的第一进球端部2a位于第一出球端部2b的上方,耐磨钢球自第一进球端部2a向第一出球端部2b自由滚动;上层轨道3的第二进球端部3a位于第二出球端部3b的上方,耐磨钢球自第二进球端部3a向第二出球端部3b自由滚动。这样一来,耐磨钢球在下层轨道2和上层轨道3上均是在自重下自由滚动,无需动力,方便实施,同时也改善耐磨钢球冷却的均匀性。

冷却风机4有多个,其中多个冷却风机4并排且间隔分布在第一床体11和第二床体12的底部。这样形成风向上,将余热的热量向上吹,从而对冷却后耐磨钢球进行预设,进而充分利用锻造耐磨钢球的余热。
第一轨道本体21和第二轨道本体22位于冷却风机4的上方。此时的余热利用率处于最佳状态。
本例中,热移位装置还包括设置在第一出球端部2b的出球接驳器5、设置在第二进球端部3a的接球轨道6,钢球提升器T将出球接驳器5传出的耐磨钢球提升至接球轨道6。

自动卸球组件T4与提升斗T21配合,在提升座T20在所对应的自动卸球组件T4所构成的卸料区内上下运动中驱动提升斗T21翻转卸料或翻转复位。
具体的,自动卸球组件T4包括设置在接球轨道5一侧的弧形导轨T40、以及设置在提升斗T21相对侧的导轮T41,其中导轮T41能够在弧形导轨T40中滑动,当向上抬升时,导轮T41自弧形导轨T40的下部向上部移动,并驱使的提升斗 T21水平翻转,位于提升斗T21内耐磨钢球自由卸载至接球轨道5上,当向下复位时,导轮T41自弧形导轨T40的上部向下部移动,并驱使的提升斗T21翻转复位,导轮T41脱离弧形导轨T40时,提升斗T21架设在提升座T20上。在弧形导轨和导轮的配合下,可在提升座上行的过程中自动翻转卸球,在提升座下行的过程中自动翻转复位。
本例中,弧形导轨T40有两条,且对应设置在接球轨道5的相对两侧,导轮T41对应设有两个,且分别设置在提升斗T21的相对两侧。这样一来,通过双弧形导轨的设置,使得提升斗的翻转动作更加稳定的实施。
导轮T41对应设置在直角梯形上底和斜边所在的拐角处,且位于提升斗T21的相对侧。此时所提供的驱动力最佳,便于实施提升斗的翻转。

此外,驱动器T3为移动小车,移动小车在提升轨道上移动,提升座T20与移动小车相固定连接。
综上,本实施例的耐磨钢球锻造余热进行耐磨钢球热处理工艺,其包括如下步骤:
1)、将锻造后800±5℃的耐磨钢球通过送料单元C向双层料床1的进料端1a逐个地传输;

同时,本例中耐磨钢球的提升过程如下:
出球接驳器5将耐磨钢球传输至提升斗T21内后,由移动小车沿着提升轨道向上移动,直到位于两侧导轮T41自弧形导轨T40接触,并在继续上升的过程中,导轮T41沿着弧形导轨T40运动并逐步带动提升斗T21绕着转轴z水平翻转,位于提升斗T21中耐磨钢球自由滚落至接球轨道5上,完成卸载后,移动小车向上复位,此时的导轮T41自弧形导轨T40上部向下部移动,直至导轮T41脱离弧形导轨T40,此时的提升斗T21由翻转卸料状态逐步翻转复位,直至提升斗T21自斗底板210水平架设在提升座T20上并继续下落至初始位置,等待下一个耐磨钢球的送料提升。
