Description

桶身激光焊接机及其使用方法 技术领域
本发明属于钢桶生产设备领域，涉及桶身激光焊接机及其使用方法。
背景技术
在钢桶的制作过程中，通常首先是将原材料的一定规格的钢板进行卷曲，并使得钢板形成圆筒形，之后通过焊接的方式将钢板的两端焊接起来。
现有的焊接钢桶两端的方法，主要是采用钢板搭缝电阻焊接，此方法耗电量大、且耗搭缝钢材、钢板易变形、焊缝又不美观，特别是当材料选用镀锌板或覆膜板时，后续还要人工磨边、耗损人力、电力和场地等；环境也受到严重污染，实用性较低。
发明内容
本发明的目的在于提供桶身激光焊接机及其使用方法，旨在解决实用性低的问题。
为解决上述技术问题，本发明提供了一种桶身激光焊接机，包括主机架、设置于所述主机架上的压轮装置以及激光焊接装置，所述激光焊接装置包括激光头，所述压轮装置包括有沿x向分布的若干组压轮组件，每组所述压轮组件均包括有若干个压轮，每组所述压轮组件中的若干个所述压轮均为圆弧形分布，且分别具有一分布直径，所述压轮装置包括有一入料端和一出料端，所述入料端和所述出料端位于所述压轮装置x向的两端，若干个所述分布直径沿着x向进行逐渐减小，所述激光头正对于所述出料端。
本发明进一步设置为，所述压轮组件还包括有支撑杆，所述压轮转动连接于所述支撑杆。
本发明进一步设置为，所述压轮的外壁为圆弧形。
本发明进一步设置为，每组所述压轮组件中均包括有三个所述压轮。
本发明进一步设置为，若干组所述压轮组件沿x向均匀分布。
本发明进一步设置为，所述主机架上还设置有支撑装置，所述支撑装置外切于所述分布直径。
本发明进一步设置为，所述支撑装置包括支撑轮和支撑件，所述支撑件固定连接于所述主机架，所述支撑轮转动连接于所述支撑件。
本发明进一步设置为，所述支撑装置设置有两个，两个所述支撑装置对称分布于所述压轮组件的两侧。
本发明还提供了一种使用如上任一项所述桶身激光焊接机的方法，包括以下步骤：
S1，将钢桶输送至压轮装置中，其中钢桶的始端从入料端输送入压轮装置；
S2，钢桶继续朝着x向活动，随着钢桶的活动，钢桶也受到了压轮的挤压而逐渐形变；
S3，钢桶活动至出料端，钢桶形成完整的圆柱形，激光焊接装置运行，激光头对钢 桶进行焊接；
S4，钢桶的尾端从出料端输送出，完成焊接。
与现有技术相比，本发明提供了桶身激光焊接机及其使用方法，在焊接桶身的时候，桶身是圆弧形或者半圆形通过入料端进入到压轮装置中，然后随着圆弧形的钢桶的继续活动，钢桶也受到了压轮组件中各个压轮的挤压作用，并逐渐变成完整的圆柱形，当桶身纵截面变成完整的圆柱形后，激光焊接装置对桶身进行了激光焊接，焊接完成后，如果是长条形的圆筒形结构，即可根据实际需要进行纵向截断从而获得想要的桶身长度；其中由于该过程在焊接时，桶身的两端处于一个抵触的状态，即桶身的两端之间没有搭边，这样就使得焊接的效果更好，同时由于本过程是通过激光焊接进行的，因此也可以较好的防止环境污染等，实用性高。
附图说明
图1是本发明桶身激光焊接机一实施例的纵向结构图；
图2是本发明桶身激光焊接机一实施例的结构示意图；
图3是本发明桶身激光焊接机中若干组压轮组件的排布示意图。
其中，1、主机架；2、激光焊接装置；3、激光头；4、压轮；5、入料端；6、出料端；7、支撑装置；7a、支撑轮；7b、支撑件。
具体实施方式
以下结合附图和具体实施例对本发明提出的桶身激光焊接机及其使用方法作进一步详细说明。根据下面说明和权利要求书，本发明的优点和特征将更清楚。需说明的是，附图均采用非常简化的形式且均使用非精准的比例，仅用以方便、明晰地辅助说明本发明实施例的目的。附图中相同或相似的附图标记代表相同或相似的部件。
一种桶身激光焊接机，如图1至图3所示，包括主机架1、设置于所述主机架1上的压轮装置以及激光焊接装置2，所述激光焊接装置2包括激光头3，所述压轮装置包括有沿x向(即图2中的水平向)分布的若干组压轮组件，每组所述压轮组件均包括有若干个压轮4，每组所述压轮组件中的若干个所述压轮4均为圆弧形分布，且分别具有一分布直径，所述压轮装置包括有一入料端5和一出料端6，所述入料端5和所述出料端6位于所述压轮装置x向的两端，若干个所述分布直径沿着x向进行逐渐减小，所述激光头3正对于所述出料端6。
所述压轮组件还包括有支撑杆，所述压轮4转动连接于所述支撑杆。所述压轮4的外壁为圆弧形。每组所述压轮组件中均包括有三个所述压轮4。若干组所述压轮组件沿x向均匀分布。
所述主机架1上还设置有支撑装置7，所述支撑装置7外切于所述分布直径。所述支撑装置7包括支撑轮7a和支撑件7b，所述支撑件7b固定连接于所述主机架1，所述支撑轮7a转动连接于所述支撑件7b。所述支撑装置7设置有两个，两个所述支撑装置7对称分布于所述压轮组件的两侧。
本发明还提供了一种使用如上任一项所述桶身激光焊接机的方法，包括以下步骤：
S1，将钢桶输送至压轮装置中，其中钢桶的始端从入料端5输送入压轮装置；
S2，钢桶继续朝着x向活动，随着钢桶的活动，钢桶也受到了压轮4的挤压而逐渐形变；
S3，钢桶活动至出料端6，钢桶形成完整的圆柱形，激光焊接装置2运行，激光头3对钢桶进行焊接；
S4，钢桶的尾端从出料端6输送出，完成焊接。
本发明提供的桶身激光焊接机及其使用方法，在焊接桶身的时候，桶身是圆弧形或者半圆形通过入料端5进入到压轮装置中，然后随着圆弧形的钢桶的继续活动，钢桶也受到了压轮组件中各个压轮4的挤压作用，并逐渐变成完整的圆柱形，当桶身纵截面变成完整的圆柱形后，激光焊接装置2对桶身进行了激光焊接，焊接完成后，如果是长条形的圆筒形结构，即可根据实际需要进行纵向截断从而获得想要的桶身长度；其中由于该过程在焊接时，桶身的两端处于一个抵触的状态，即桶身的两端之间没有搭边，这样就使得焊接的效果更好，同时由于本过程是通过激光焊接进行的，因此也可以较好的防止环境污染等，实用性高。
其中每组压轮组件中都包括有三个压轮4，这样在实际生产的时候能使得所使用的压轮4个数最少，投入成本最低；而若干组压轮组件是沿着x向均匀分布的，这样能够使得钢桶的形变是逐渐进行的，防止了钢桶形变变化太快而引起钢桶产生损坏，提高了加工质量。
其中由于压轮4是转动连接在支撑杆上的，这样钢桶与压轮4之间的摩擦力就较小，减小了钢桶的损耗；而且由于压轮4的外壁时圆弧形的，这样就加大了钢桶与压轮4之间的抵触总面积，更进一步的防止了钢桶发生形变；同样钢桶在运行时支撑装置7能够对钢桶起到支撑的作用；且支撑轮7a可以在钢桶的带动作用下发生转动，因此也对钢桶起到了保护作用。
需要说明的是，本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
上述描述仅是对本发明较佳实施例的描述，并非对本发明范围的任何限定，本发明领域的普通技术人员根据上述揭示内容做的任何变更、修饰，均属于权利要求书的保护范围。
