我厂过去研制的一台一万焦耳储能点焊机,使用率较低。为此,在传统点焊机结构的基础上又设计了一套薄膜式的小气缸,安装在该焊机的上机臂上(见图1),即可根据不同需要,通过一个手动转换阀进行气路转换,以选择不同的气缸压力。因此,一台焊机具有两套加压机构,既适应大件的焊接,也可以满足小薄件焊接的要求。经过我厂和几个兄弟厂几年的应用,认为该设备具有两套压力机构,结构简单,使用方 I plant in the past developed a 10,000 Joule energy spot welding machine, the use of lower rates. To this end, in the traditional spot welding machine structure based on the design of a small membrane-type cylinder mounted on the machine arm (see Figure 1), according to different needs, through a manual conversion valve Perform gas changeover to select different cylinder pressures. Therefore, a welder with two sets of pressure mechanism, both to adapt to large welding, thin welding can meet the requirements. After several years of plant and several brothers plant application, that the device has two sets of pressure agencies, simple structure, the use of party
