近年来,由于市场对汽门质量有了新的要求,国内汽门生产厂家都在上“摩擦焊接”工艺,所采用的设备大多是“HSMZ-13”型摩擦焊机（以下简称“摩擦焊”）。我厂对该机进行了调试,现将调试过程中在电路方面采取的一些改进措施作一简要介绍。 在调试过程中,发现该机存在几个主要问题: 1、电气逻辑设计无法保证加工程序的执行,各程序间联锁多而杂,电路存在多处“竞争冒险” 2、电流继电器选择不合适,不能实现“功率极值控制法”,焊接质量得不到保证。 3、使用元件多,仅程序控制部分使用的中间继电器和行程开关就多达29个,触头利用率低。
In recent years, due to the market has a new valve quality requirements, the domestic valve manufacturers are on the “friction welding” process, the equipment used are mostly “HSMZ-13” type friction welding machine (hereinafter referred to as “friction welding ”). I plant the machine was debugged, now the debugging process in the circuit to take some improvements to make a brief introduction. In the process of debugging, found that the machine there are several major problems: 1, the electrical logic design can not guarantee the implementation of processing procedures, interlocking between procedures and more, the circuit there are multiple “competition risk” 2, the current relay selection is not appropriate , Can not achieve the “power limit control method”, welding quality can not be guaranteed. 3, the use of components and more, only the program control part of the use of intermediate relay and travel switch up to 29, contact utilization rate is low.
