缝焊机又叫滚焊机，缝焊是一种形成结合的金属焊接.在焊接时,焊件压紧在两焊轮之间,转动焊轮带动焊件并通电,焊接电流通过焊件局部发热,形成先后重叠的焊点从而构成连续的焊缝,实现性连接.广泛用于箱体:如汽车\摩托车油箱,桶体:如钢桶,以及成形板材工件,如轮圈、消声、暖气片等的缝焊.
缝焊机通常由机架、加压机构、焊轮(电极)、焊接电源、调速传动机构及控制器等组成.
1. 加压机构:传递压力,均匀调节焊轮间的压力并能补偿电极磨损;
2. 焊轮:采用内\外水冷,导电块采用钝银瓦结构,导电性能好并有自动补偿银瓦磨损的功能;
3. 调速传动机构:采用变频调速\齿轮减速器传动;
4. 缝焊机有纵焊种横焊两种形式,适合各种工件焊接需要.
整机特点
1. 包含两种基本的类型：横缝焊接和纵缝焊接。
2. 一台机器可以同时具备横缝焊接和纵缝焊接两种功能，只要将转换一下上电极轮的方向和更换一下下电极臂，就可以在几分钟内完成两种焊接方式的切换。
3. 单轮驱动，保证上下两轮切线速度一致。
4. 广泛应用于五金、家电、汽车、摩托车油箱、制盆、制罐等金属制造和加工行业。
Features of the Machine
1. There is two standard models: Transversal Seam Welding Model and Longitudinal Seam Welding Model.
2. Also one machine can be used as both transversal seam welding and longitudinal seam welding, only need to change the direction of upper seam wheel head and change the lower welding head and welding arm within minutes.
3. Driven one head and free the other head. The two seam wheels have the same tangential speed.
4. Widely used in hardware, appliances, automotive, manufacturing pots, can, fuel tank, tank producing and other metal manufacturing and processing industries.
