小型加热炉是科研院所及厂矿常用的热处理或加热设备。炉门是唯一的送取料口，在加热过程中炉门的密封可保证炉内温度的控制，防止能量的浪费，防止有害气体的散失对操作者造成的伤害。由于炉门经常处在高温下工作，所以需要操作机构来实现炉门的启闭动作。本文在考察各种工业加热炉炉门启闭方式的基础上，针对试验用小型加热炉的特点采用简单的平面四连杆机构实现炉门的启闭运动。在设计过程中考虑到小型加热炉对洁净工作环境的要求及炉门作为高温运动部件的特殊要求，并考虑到操作的方便性，采用优化设计的方法合理确定四连杆各杆长度及两活动铰链和两固定铰链的位置，从而满足炉门恰当的运动轨迹。对炉门结构作了合理的设计满足炉门的密封保温作用。整个运动由电动机提供动力，通过恰当选取电动机和减速器以及合理布置其位置，达到与小型加热炉的最佳匹配，实现炉门的自动启闭。本设计力争以较少的运动部件，较小的布局空间，简单的运动方式，达到炉门灵活自动启闭，并满足加热炉对炉门的特殊功用要求。<o:p></o:p>

小型加热炉是科研院所及厂矿常用的热处理或加热设备，为了保证加热炉的温度可控，使炉内工件能够按设定的温度曲线变化，以得到良好的材料内部组织，炉门是唯一的送取料口，在加热过程中，炉门的密封可保证炉内温度的控制，防止能量的浪费，防止有害气体的散失对操作者造成伤害。由于炉门经常处在高温下工作，所以需要由操作机构来实现炉门的启闭。<o:p></o:p>

   加热炉是工业炉窑的一大类别，是指被加热的物料在炉内基本不发生物态变化和化学反应的炉子。对于冶金行业来说，加热炉是指金属压力加工前的加热和金属制成品及半成品的热处理等用炉。小型加热炉是科研院所及厂矿常用的热处理或加热设备。随着科学技术的不断发展，加热炉的理论和实践在不断深化和日趋完善，加热炉的结构型式也在不断演进。优质、高产、低消耗的新式炉型不断涌现，加热炉的结构目前仍处在不断变革之中，以满足生产工艺对炉子的技术经济要求，即经济、高产、低消耗、炉子寿命长、劳动条件好。<o:p></o:p>

在加热炉中，为了装料、卸料、出渣和观察炉内的工作情况必须在炉墙上开设炉门孔。炉门的材料通常采用铸铁，内里衬以耐火砖或其它耐火材料，也有采用焊接结构的。由于工业用加热炉一般用来加热大型工件，炉体较大，炉门也相应较大较重，故常采用升降机构。这种机构有的采用人力脚踏传动机构或手摇链轮配以平衡重锤筒装置，而对那些很重的大型炉门升降机构则常采用电动机带动或由液压装置升降。<o:p></o:p>
这种采用升降装置的炉门与炉膛不可能严格密封，会使部分热量外溢，从而使炉内温度波动，还会使有害气体进入炉内进而影响加热工件的性能和质量，对于试验用小型加热炉这种升降装置显然不合适。升降门行程较长，这对于体积较小的小型加热炉难以布置。科研院所用小型加热炉加热工件或对其进行热处理一般用以研究目的，故需严格控制炉温，严格按设计要求变温并需控制炉内气氛，以免影响工件加热质量，达不到试验目的。<o:p></o:p>

本课题要求加热炉炉门应能自动灵活启闭，操作要简单方便，以降低操作者的劳动强度。炉门在开启和关闭时与炉膛相对的高温内壁要始终背对操作者，炉门与炉体不得发生干涉。在关闭时炉门应有锁紧装置，以免因偶然因素造成门体运动而发生事故，门与炉膛要严格密封。<o:p></o:p>
鉴于升降门结构对于小型加热炉的局限，本设计采用简单的平面四连杆机构实现炉门的启闭运动。设计合理的炉门运动轨迹，然后按此轨迹确定恰当的四杆长度及两活动铰链和两固定铰链的合适位置。对于门体采用强度高、耐磨、耐热、减振性能较好的灰铸铁材料铸造成型，并设计出合理的结构，内设倒边与炉膛严密配合，以获得较佳的密封效果，其内衬耐火泥以取得较好的保温效果。整个机构动力由电动机输入，电动机通过减速器降速增矩带动四连杆机构运动，从而实现炉门的平稳自动启闭。<o:p></o:p>

由于炉门内部结构较简单，经常处在高温下工作，故采用铸造方式生成。材料选择强度、耐磨、耐热、减振性能较好的灰铸铁（HT200），这种材料适用于承受较大压力、耐磨、一定气密性的零件。<o:p></o:p>

连杆机构是由若干个刚性构件用低副（转动副或移动副）连接而成的机构，故又称低副机构。这类机构广泛地应用于各种动力机械、重型机械、机床、仪表和军事工业中，例如活塞发动机、牛头刨床、自动包装机等。<o:p></o:p>
平面四连杆机构结构简单，能实现的运动规律和轨迹各式各样，不但实际应用很广泛，而且还是组成多杆机构的基础。在此机构中与机架相连的构件称为连架杆；能作整周回转的连架杆称为曲柄；不能做整周转动的连架杆称为摇杆；能使两构件作整周相对转动的转动副称为周转副，而不能作整周相对转动的转动副称为摆动副。<o:p></o:p>
连杆机构具有的优点有：<o:p></o:p>
（1）连杆机构中的运动副都是低副，运动副元素间为面接触，故压强较小，便于润滑，所以磨损较轻，寿命长；因两构件接触表面多为圆柱面或平面，因而制造简单并可获得较高的精度；同时由于构件间的接触主要依靠运动副元素自身的几何封闭来实现，故连接可靠。<o:p></o:p>
（2）在连杆机构中，由于构件多为杆状，因此可作为操纵机构，用以实现传递远距离的运动和动力；又因连杆上不同点的轨迹是丰富多彩的封闭的高次连杆曲线，而且随着各构件相对长度的改变，连杆形状将改变，利用这些曲线可满足各种不同轨迹的要求。<o:p></o:p>
（3）在连杆机构中当取不同构件为机架时，可得到具有不同尺寸特性和不同类型的机构；此外，由于选取不同的原动件和从动件，不仅可以满足不同的运动要求，而且可作增力或减力机构；另外，当原动件以同样的运动规律运动时，通过改变各构件的相对尺寸，可使从动件得到不同的运动规律。<o:p></o:p>

本设计用平面四连杆机构实现炉门的启闭，各杆尺寸的确定和各铰链的位置由图解法求解。<o:p></o:p>
（1）图解法原理：用图解法设计四杆机构是根据设计要求，通过作图确定四个铰链的位置进而求得各杆长度。铰链的位置是根据四连杆机构各铰链之间相对运动的几何关系来确定的。在铰链四杆机构ABCD中，设B，C为连杆上两个活动铰链中心，A,D为机架上两固定铰链中心，它们之间的运动几何关系为：活动铰链如B所占据的各点Bi（i=1,2,…，N）必位于以固定铰链A为圆心，以AB杆的长度为半径的圆上。反之，固定铰链A也一定位于活动铰链B的各点位Bi（i=1,2,…，N）所在圆的圆心上。<o:p></o:p>
求固定铰链中心的位置：如已知连杆上活动铰链B的预定位置点Bi(i=1,2,…N)要求确定对应固定铰链A的位置,则求解方法为：作各位置点Bi (i=1,2,…N)连线的中垂线,其交点即为所求即为所求固定铰链A的位置,此方法可称为圆心法。<o:p></o:p>
(2)炉门运动过程及已知条件如下图2.2 所示：<o:p></o:p>
炉门各部分大小尺寸已知,两活动铰链B,C位置已知,炉门关闭位置和开启位置如图示。需根据已知条件确定固定铰链A,D位置。<o:p></o:p>

（4）炉门在开启时不与炉体发生干涉的验证<o:p></o:p>
如附图所示，炉门完全开启和关闭时位置已定，各铰链位置和各杆长度通过作图法已确定。炉门在按顺时针翻转过程中最易与炉体发生干涉的危险点为门顶的E点所在的楞边，故需描绘出E点运动轨迹。图中弧<v:shape id=_x0000_i1068 style="WIDTH: 27pt; HEIGHT: 18pt" o:ole="" type="#_x0000_t75"> <v:imagedata o:title="" src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image060.wmz"></v:imagedata></v:shape>为活动铰链C点运动轨迹，<v:shape id=_x0000_i1069 style="WIDTH: 27pt; HEIGHT: 17.25pt" o:ole="" type="#_x0000_t75"> <v:imagedata o:title="" src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image062.wmz"></v:imagedata></v:shape>为活动铰链B点运动轨迹，在<v:shape id=_x0000_i1070 style="WIDTH: 27pt; HEIGHT: 18pt" o:ole="" type="#_x0000_t75"> <v:imagedata o:title="" src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image064.wmz"></v:imagedata></v:shape>上依次确定主动曲柄AC上C点的相应位置，按作图法确定相应活动铰链B在<v:shape id=_x0000_i1071 style="WIDTH: 27pt; HEIGHT: 17.25pt" o:ole="" type="#_x0000_t75"> <v:imagedata o:title="" src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image065.wmz"></v:imagedata></v:shape>上的相应位置并通过炉门尺寸依次确定E点相应位置，如图所示（<v:shape id=_x0000_i1072 style="WIDTH: 107.25pt; HEIGHT: 18pt" o:ole="" type="#_x0000_t75"> <v:imagedata o:title="" src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image066.wmz"></v:imagedata></v:shape>）,将各点连成一光滑曲线即得E点运动轨迹,由图示可知,E点没有和炉体发生干涉，故此四连杆机构能够满足预定炉门轨迹设计要求。<o:p></o:p>
（5）炉门在启闭过程中需输入最大扭矩位置的确定<o:p></o:p>
如下图2.4所示,比例为1:4,<o:p></o:p>
当主动杆AC扭矩最大时为对固定铰链C提供切向力最大位置。在不考虑各杆重量及运动副间摩擦力时，由观察可得在门关闭过程中重力起阻力作用，当门升起到图示位置时AC杆运动到<v:shape id=_x0000_i1073 style="WIDTH: 27pt; HEIGHT: 18pt" o:ole="" type="#_x0000_t75"> <v:imagedata o:title="" src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image068.wmz"></v:imagedata></v:shape>位置此时AC杆呈水平,重力G相对于固定铰链C的力臂达最大，此时阻力矩达最大。<o:p></o:p>

炉门在开启和关闭过程中轴的转向相反，其间有冲击，因此选用弹性柱销连轴器，这种连轴器传递转矩的能力很大，结构更为简单，安装制造方便，耐久性好，有一定的缓冲和吸振能力，允许被连接两轴有一定的轴向位移以及少量的径向位移和角位移，适用于轴向窜动较大、正反转变化较多和启动频繁的场合。<o:p></o:p>

平面四杆机构各杆长和铰链的位置要精确按设计要求加工装配，各运动件不得互相干涉，如各杆运动时不得与炉门端面相摩擦。
对于和炉体相焊接的零部件，在加工之前先将其焊接到相应位置再按设计要求进行加工，以确保相关件的位置精度。

本装置结构简单，构件较少，炉门开启和关闭时间较短，相对运动件连续运转时间不长，故磨损较小。减速器和连轴器要加注足量润滑油，其它相配合运动部件如门轴处，在其运动表面涂一层二硫化钼润滑，定期检查磨损情况。

本设计通过电动机输入动力，减速器减速带动四连杆机构运动实现加热炉炉门的自动启闭。在设计中炉门采用合理的构造通过斜边和余边实现与炉门的密封，炉门内衬耐火泥材料，可以达到较好的保温效果。用简单的四连杆机构实现炉门向内翻转，使高温的内门面始终背对操作者。连轴器配以制动器可实现炉门的定位制动，防止其意外转动发生事故。选用转速较低的电动机和大传动比结构紧凑的蜗杆减速器，使炉门启闭时运动平稳缓慢，避免引起过大的冲击破坏相关的连接运动件的精度。本装置与相应的开关装置相配可实现远距离操纵，达到自动控制炉门启闭减轻操作者劳动强度的目的。
由于时间仓促，经验不足，设计和选用的一些零部件可能在实际应用中会出现一些问题，需进一步改进和完善。

哥们，能不能看看图纸啊，让我参考一下，我现在准备设计一自动开启炉门，让其上下翻转，我的方案是设计一自锁机构，上翻时通过自锁机构让其固定，结构应尽量简单、紧凑，有时间我们聊聊，我的QQ:25338834，谢谢！
