Description

一种用于铜件与钢件焊接的焊枪
技术领域
本发明涉及一种用于铜件与钢件焊接的焊枪。
背景技术
氩弧焊是在普通电弧焊的原理的基础上，利用氩气对金属焊材的保护，通过高电流使焊材在被焊基材上融化成液态形成熔池，使被焊金属和焊材达到冶金结合的一种焊接技术。焊枪是实现焊接的关键部件，现有的焊枪通过电弧在钨极和工件之间燃烧，将焊丝熔化与工件熔接在一起以此实现焊接，上述焊枪的钨极作为电极，钨极需经常更换，导致焊枪的使用寿命短和使用成本高。
发明内容
本发明要解决的技术问题是，提供一种结构简单、使用寿命长和使用成本低的焊枪。
为了解决上述技术问题，本发明提供了一种如下结构的用于铜件与钢件焊接的焊枪，包括枪架，其结构特点是:所述枪架为可导电枪架，枪架上连接有连接套，连接套上连接有绝缘套，绝缘套上连接有外枪管，外枪管的端部连接有喷嘴；喷嘴、外枪管、绝缘套和连接套的内腔形成一进气腔，进气腔仅靠近枪架的一端封闭，进气腔上设有进气口，进气腔内设有内枪管，内枪管一端穿出进气腔的封闭端且其另一端上连接有导电嘴，导电嘴位于喷嘴内，内枪管和导电嘴的内腔形成焊丝通道，内枪管和导电嘴与进气腔的内壁之间均设有间隙，内枪管与枪架电连接以使焊机的焊接电流能通过枪架、内枪管传到导电嘴上。
所述绝缘套的内壁上设有环凸，环凸将绝缘套的内腔分隔为连接套插入腔和外枪管插入腔，环凸上设有连通连接套插入腔和外枪管插入腔的连通孔；连接套插在连接套插入腔内、内枪管插在外枪管插入腔内，从而实现连接套、绝缘套和内枪管的依次插装的连接方式。
所述外枪管通过端面与枪架进行连接，从而使枪架将进气腔的一端封闭；所述枪架上设有内枪管穿装孔，内枪管穿出进气腔的一端穿过内枪管穿装孔，内枪管与内枪管穿装孔密封配合且内枪管与枪架固接。
所述外枪管的管壁内环设有进水腔，进水腔的一端设有进水口、另一端设有出水口。
本发明使用时，焊丝直接通过内枪管到达焊接区，且焊丝作电极，并被不断熔化填入熔池，冷凝后形成焊缝，因而避免了现有产品的钨极需要更换的缺点，因而具有结构简单、使用寿命长和使用成本低的优点。
附图说明
下面结合附图对本发明的具体实施方式作进一步的详细说明：
图1是本发明的结构示意图。
具体实施方式
如图1所示，用于铜件与钢件焊接的焊枪包括枪架1，枪架1用于焊枪与焊机连接，所述枪架1为可导电枪架，例如可用金属材料制成。枪架1上连接有连接套2，连接套2上连接有绝缘套3，绝缘套3上连接有外枪管4；所述绝缘套3的内壁上设有环凸10，环凸10将绝缘套3的内腔分隔为连接套插入腔和外枪管插入腔，环凸10上设有连通连接套插入腔和外枪管插入腔的连通孔；连接套2插在连接套插入腔内、内枪管7插在外枪管插入腔内，从而实现连接套2、绝缘套3和内枪管7的依次插装的连接方式；连接套2、绝缘套3和内枪管7依次插装后，绝缘套3的内腔只剩下连通孔所在的部段。外枪管4的端部连接有喷嘴5；喷嘴5、外枪管4、绝缘套3和连接套2的内腔形成一进气腔6。进气腔6仅靠近枪架1的一端封闭，即所述外枪管4通过端面与枪架1进行连接，从而使枪架1将进气腔6的一端封闭。进气腔6上设有进气口15，进气腔6内设有内枪管7，内枪管7一端穿过设在枪架1上的内枪管穿装孔，从而实现内枪管7的一端穿出进气腔6的封闭端。内枪管7与内枪管穿装孔密封配合且内枪管7与枪架1固接，以使内枪管7与枪架1形成电连接，从而可使焊机的焊接电流能通过枪架1、内枪管7传到导电嘴8上。枪架1上还连接有套装在内枪管7穿出部段上的加强套14，以提高内枪管7的连接强度。内枪管7的另一端上连接有导电嘴8，导电嘴8位于喷嘴5内，内枪管7和导电嘴8的内腔形成焊丝通道9，内枪管7和导电嘴8与进气腔6的内壁之间均设有间隙。外枪管4的管壁内环设有进水腔11，进水腔11的一端设有进水口12、另一端设有出水口13。
本发明的使用方式如下所述。通过枪架1将焊枪与焊机连接后并将焊机的阳极与枪架1进行电连接，将进水口12和出水口13接通循环水以进行冷却，将进气口15与氩气供送装置连通，以进行气体保护，将焊接工件与焊机的阴极进行电连接，通过送丝机将焊丝送入内枪管7，启动焊机就可进行焊接。
