具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
实施例
参见附图1～图10所示，本实施例中的一种全自动床垫弹簧边框制作设备，其采用的折弯方法如下：
步骤1、首先将钢丝进行校直，并根据实际需要定长切断；
步骤2、将切断好的钢丝两端进行对接，使其形成钢丝圈，在本实施例中对接的方式为焊接，当然也可以采用其它的连接方式，如采用连接件将钢丝的两端夹紧固定；
步骤3、针对钢丝圈进行定长折弯，将环状钢丝圈折成矩形结构的弹簧边框。
上述弹簧边框制作设备包括用于支撑的底座机架1，所述底座机架1上设置校直送丝装置和焊接机构7，所述底座机架1上设置有导向板，并在导向板上设置有钢丝导轨机构3。如图2所示，所述校直送丝装置包括依次衔接的校直机构2、送丝机构4和切断机构5，结合图3和图4可知，所述焊接机构7包括固定焊接部和与固定焊接部相对移动的移动焊接部，放置在固定焊接部上的钢丝一端固定不动，放置在移动焊接部上的钢丝另一端可沿着相应的导轨来回移动，当钢丝的两端相接触时实现电熔将钢丝焊接成钢丝圈。为了方便钢丝的一端输送至固定焊接部，所述切断机构5的输出端与钢丝导轨机构3的一端衔接，所述钢丝导轨机构3的另一端与所述固定焊接部衔接，这样经过校直后的钢丝能够顺着钢丝导轨机构3限定的轨道移动至固定焊接部，并固定下来。为了方便钢丝的另一端输送至移动焊接部，所述切断机构5外侧还设置有第一平移机构6，所述第一平移机构6将切断机构5切断后的钢丝移动至移动焊接部。所述底座机架1上方设置有平移机架201，所述平移机架201的一端通过支撑架A固定在底座机架1上，所述平移机架201的另一端通过支撑架B与折弯装置9相连，由于折弯装置9设置在底座机架1外侧并悬空设置，使得折弯装置与底座机架1之间形成落料空间。当设置在平移机架201上的第二平移机构将焊接完成后的钢丝圈移动至折弯装置9，经折弯装置按照尺寸规定折弯成床垫钢丝边框，当床垫钢丝边框折弯成型后经推料机构将其推入落料空间，并掉落在地面上。上述描述为整套设备运行的基本原理结构，通过上述方式能够一次性、自动化将钢 丝折弯成床垫钢丝边框，无需人工进行搬运，同时整套设备结构紧凑，节约了空间，提高了空间利用率，极大的提升了床垫钢丝边框的成型效率。
图2为钢丝前端处理的立体图，从图中可以了解到钢丝的校直、送丝、切断和焊接工序。具体来看，钢丝的校直采用校直机构2，上述校直机构2包括了垂直校直部和水平校直部，垂直校直部和水平校直部采用的原理和实现的方式相同，具体如下：将垂直校直部和水平校直部依次放置在校直底板21上，上述校直底板21安装在底座机架1上，钢丝首先穿过垂直校直部，然后在穿过水平校直部，同时保持钢丝处于拉直状态，不会出现折弯现象。所述垂直校直部包括两块安装在校直底板21上的垂直校直支撑板23，两块垂直校直支撑板23上垂直放置有垂直校直基板24；所述水平校直部包括上两块安装在校直底板21上的水平校直支撑板22，两块所述水平校直支撑板22上水平放置有水平校直基板25；上述垂直校直基板24和水平校直基板25上均设置有一组校直滚轮。上述校直滚轮包括固定滚轮26和夹紧滚轮27，垂直校直基板24和水平校直基板25上均设置有放置夹紧滚轮27的滑槽和调节旋钮28，上述调节旋钮28与夹紧滚轮27相连，用于调节夹紧滚轮27在滑槽内的位置。
当钢丝经过校直机构2校直后输送至送丝机构4，所述送丝机构4包括齿轮箱A41，所述齿轮箱A41的驱动轴与减速机A43相连，所述减速机A43与伺服电机C42相连。所述齿轮箱A41的输出轴有四个，并矩形分布在齿轮箱A41上。每个输出轴上均安装有导向轮A45，上下两个导向轮A用于夹紧钢丝，使其向前输送。在本实施例中，位于上方的两个导向轮A可上下垂直移动，其采用的方式是将与上述两个导向轮A相连的驱动轴直接与横板相连，上述横板的两端延伸至齿轮箱A41的外部，并与相应的夹紧气缸C相连。当放置钢丝时将收缩夹紧气缸C将横板抬起，这时候相应的齿轮会脱离啮合状态，处于分离状态；当 钢丝放好后伸展夹紧气缸C将上导向轮A下压，使其与下导向轮A配合来夹紧钢丝，同时齿轮箱A41内相应的齿轮分离状态转换为啮合状态，实现在伺服电机C42的驱动下输送钢丝。
在本实施例中，送丝机构4、切断机构5、焊接机构7和限位机构8均安装在水平面板44上，水平面板44安装在底座机架1。
如图5所示，所述切断机构5包括安装在水平面板44上的切断箱，所述切断箱内设置有相互配合的定刀座57和动刀座，所述定刀座57上设置有放置动刀座的槽体，所述定刀座57上设置有与上述槽体相连通的定刀55，所述定刀55上设置有供钢丝穿过的输送通道；所述动刀座的下端设置有动刀，所述动刀座的上端设置有压块56，所述切断箱上设置有与压块56相连的驱动气缸51。这样在驱动气缸51的驱动下使得动刀能够上下移动，进而可以使得定刀55内的钢丝切断。上述切断箱包括切断箱底板54、切断箱顶板52和用于将切断箱底板54、切断箱顶板52相连的切断箱侧板53。
结合图3和图4可知，所述焊接机构7包括安装在水平面板44上的基础板71，所述基础板71内设置有固定焊接部和移动焊接部，位于固定焊接部与移动焊接部之间所在的基础板71底部设置有限位机构8，所述限位机构8用于限定固定焊接部上钢丝的端部位置。
所述移动焊接部包括安装在基础板71上的右支架762和左支架764，位于右支架762和左支架764之间设置有导向柱765和传动丝杠A，所述导向柱765上均设置有导向套，两个导向套与传动丝杠A上的滑座均与滑移板763固定相连，所述滑移板763上设置有连接板A766。传动丝杠A的一端与伺服电机A761相连，使得连接板A766能够前后移动。在连接板A766上设置有绝缘板A，并在绝缘板A上设置有定模底板A，所述定模底板A上设置有紫铜垫A，所述紫铜垫 A上安装有焊机下模A；位于焊机下模A上方设置有可上下移动的焊机上模A，所述焊机上模A上固定在上模座A上，所述上模座A安装在上导板A上，所述上导板A通过连接头与夹紧气缸A相连。所述夹紧气缸A通过L型连接板79与连接板A766相连。这样在夹紧气缸A能够驱动焊机上模A下移将放置在焊机下模A上的钢丝固定。
所述固定焊接部与移动焊接部的部分结构相同，包括安装在左支架764上的绝缘板B，并在绝缘板B上设置有定模底板B781，所述定模底板B781上设置有紫铜垫B，所述紫铜垫B上安装有焊机下模B78；位于焊机下模B78上方设置有可上下移动的焊机上模B77，所述焊机上模B77上固定在上模座B上，所述上模座B安装在上导板B75上，所述上导板B75通过连接头与夹紧气缸B73相连。为了方便焊机上模B77下移时的稳定性，在基础板71和L型连接板79上均设置有辅助滑轨741，所述辅助滑轨741上均设置有与上导板B75相连的辅助滑块742。使用时当钢丝的两端均固定在固定焊接部和移动焊接部上后，对两侧的紫铜垫进行供电，同时将移动焊接部往固定焊接部一侧移动，当钢丝的两端相接触后会产生电熔现象，使得钢丝两端焊接在一起。
结合图7所示，所述第一平移机构6安装在L型连接板79上。所述第一平移机构6包括安装在L型连接板79上的长杆气缸61，位于长杆气缸61下方所在的L型连接板79上设置有平移滑轨62，所述平移滑轨62上设置有相应的滑块，并在该滑块上设置有平移板64，所述平移板64的一端与长杆气缸61的顶杆通过连接件相连。所述平移板64上设置有气动手指A65，所述气动手指A65上设置有用于夹持钢丝的钢丝仿形手A66。为了使钢丝仿形手A66移动位置位于移动焊接部的焊机下模A上，在L型连接板79上还设置有限位组件，用于限定气动手指A65移动的最远距离。
当长杆气缸61处于未展开时，钢丝仿形手A66位于切断机构5的输出端外侧。为了便于钢丝仿形手A66夹住钢丝，在切断机构5的输出端设置有U形导槽100，同时为了方便钢丝仿形手A66夹住钢丝后移动，所述U形导槽100设计成可上下移动的。具体为：将U形导槽100的底部与衔接板103相连，所述衔接板103通过间接板102与驱动气缸101相连。当驱动气缸101展开时，U形导槽100位于切断机构5的输出端相匹配的位置，同时钢丝仿形手A66夹住U形导槽100上的钢丝，当钢丝切断后，驱动气缸101收缩将U形导槽100的位置下移，钢丝仿形手A66在长杆气缸61的驱动下运行至移动焊接部的焊机下模A上。
如图6所示，所述限位机构8包括安装在水平面板44上的垂直面板81，所述垂直面板81上设置有驱动气缸82和辅助滑轨86，所述辅助滑轨86上设置有辅助滑块，该辅助滑块上设置有导轨安装板84，所述导轨安装板84上设置有锉刀85，所述驱动气缸A82通过连接件与导轨安装板84相连。在驱动气缸A82的驱动下将锉刀向上移动，进而顶住钢丝。
如图1所示，安装在导向板上的钢丝导轨机构3由四个弧形导向部组成，每个弧形导向部均包括安装在导向板上的下弧形导向件34，所述下弧形导向件34上设置有上弧形导向件31，所述上弧形导向件31与下弧形导向件34之间限定形成供钢丝穿过的弧形导向槽。位于上弧形导向件31内侧所在的导向板上设置有固定长板32，所述固定长板32上设置有两个挤压气缸33，每个挤压气缸33的顶杆均通过连接件与上弧形导向件31相连。在本实施例中，右上方的弧形导向部的上端与U形导槽100相对应；左上方的弧形导向部的上端与固定焊接部上的焊机下模78相对应。这样钢丝的端部经过钢丝导轨机构3能够顺利的进入焊机下模78上，直至与锉刀85阻挡。位于下方的两个弧形导向部具有一定 的间隙，当钢丝被锉刀85阻挡后，钢丝会从上述间隙处延伸出来，最终获得定长的钢丝。
结合图8和图9所示，平移机架201的一端通过支撑架A固定在底座机架1上，所述平移机架201的另一端通过支撑架B与折弯装置9相连。第二平移机构包括设置在平移机架201上设置有传动丝杠D202，所述传动丝杠D202的一端与伺服电机D203相连。所述传动丝杠D202上的滑块与衔接板204相连，所述衔接板204与U形板205相连。如图8所示，U形板205的中部与衔接板204相连，U形板205的侧板分列在平移机架201的两侧，每个侧板上均设置有夹丝机构，上述夹丝机构包括安装在侧板上的驱动气缸D206和辅助滑轨207，所述辅助滑轨207上设置有辅助滑块，所述辅助滑块上设置有衔接板209，所述衔接板209上设置有气动手指B208，所述气动手指B208上设置有用于抓取钢丝的钢丝仿形手B210。
如图10所示，所述折弯装置9包括与支撑架B相连的底板91，所述底板91上安装有齿轮箱B，所述齿轮箱B的输出轴设置有主动导丝轮97，位于主动导丝轮97上设置有可上下移动的从动导丝轮。所述齿轮箱B的输入轴设置有减速机B，所述减速机B上设置有伺服电机E92，这样在伺服电机E92的带动下使得上下两个导丝轮转动，进而将钢丝向前移动。位于齿轮箱B外侧所在的底板91上设置有摇臂机构，所述摇臂机构包括摇臂94，所述摇臂94的一端设置有用于将钢丝弯转的滚轮95，滚轮95通过短轴固定在摇臂94上；摇臂94的另一端与减速机C的驱动轴相连，该减速机C与伺服电机F93相连；同时在摇臂94外侧所在的减速机C的驱动轴上还设置有轴承，并在该轴承上安装导向轮B96。当钢丝圈放置在主动导丝轮97和导向轮B96上后，将从动导丝轮下压将钢丝固定。在本实施例中，位于主动导丝轮97和导向轮B96之间还设置有辅助滚轮， 所述辅助滚轮通过连接板98与设置在齿轮箱B上的气缸相连，这样通过气缸的伸展来控制辅助滚轮是否与钢丝圈接触，一般来说，当钢丝圈放置在主动导丝轮97和导向轮B96上后，辅助滚轮即可与钢丝圈接触。在本实施例中，从动导丝轮上下移动采用设置在齿轮箱B外侧的驱动气缸H，并在齿轮箱B内设置有偏心轮，上述驱动气缸H通过摆臂与安装在偏心轮上的短轴相连，使驱动气缸H能够驱动偏心轮转动。上述偏心轮通过连杆与从动导丝轮相连的驱动轴相连，使得从动导丝轮在偏心轮转动过程中上下移动。
由于采用伺服电机驱动齿轮箱的形式进行钢丝或者钢丝圈的运行，人们可通过伺服电机和齿轮之间的运行参数计算出钢丝运行的长度。因此通过简单调试后设备就可以进行钢丝的定长截断和钢丝的定长折弯操作。
当床垫钢丝边框制作完成后，如图10所示，位于齿轮箱一侧设置有推料气缸301，所述推料气缸301的顶杆上设置有推板302。在推料气缸301的驱动下推板302会向前移动并将完成好的床垫钢丝边框推入落料空间内。
本发明所述的全自动床垫弹簧边框制作设备上还设置有控制电箱和供气罐，其中供气罐用来给上述提高的气缸供气，在使用过程中气缸的驱动采用电磁阀进行气路控制，为此，控制电箱与上述电磁阀和伺服电机相连，用于给上述设备供电及控制其运行。
本发明通过一台设备依次将钢丝的校直、定长切断、焊接成钢丝圈和将钢丝圈定长折弯成床垫钢丝边框。其采用与原有生产工艺不同的工艺步骤，先将钢丝焊接成圈后再进行折弯操作。相比于原有的生产工艺，本发明所采用的设备其占地面积小，集约化程度高，能够一次性一体化的进行床垫钢丝边框的生产，大大提高了生产效率。
以上实施方式只为说明本发明的技术构思及特点，其目的在于让熟悉此项 技术的人了解本发明的内容并加以实施，并不能以此限制本发明的保护范围，凡根据本发明精神实质所做的等效变化或修饰，都应涵盖在本发明的保护范围内。
