[0032]本次喷涂次数是完成一次喷涂自动循环过程中喷涂的实际发生次数,其数据存储在DM200中,在一次喷涂循环完成后该数值自动归零;通过查看本次喷涂次数,操作人员可实时监控喷涂任务完成的进度情况; [0032] The spraying frequency and the actual frequency is done automatically spraying a spray cycle in which data is stored in DM200, the auto-zero values ​​after one spray cycle is completed; Views by this spraying, the operator may Real-time monitoring of the progress of the spraying task is completed;

[0033]预设喷涂次数是喷涂工艺次数的需求数值;操作人员通过触摸屏面板输入预设喷涂次数至存储器DM170中;喷涂次数设定完成后,操作人员在启动自动喷涂程序后经过预设次数个循环系统停止喷涂工作; [0033] The spraying frequency and a preset number of demand values ​​spraying; spray preset number to the operator in the memory DM170 input through the touch screen panel; set times after spraying is completed, the operator starts automatically after the spraying process after a preset number of times circulatory system to stop spraying work;

[0034]为实现喷枪按照喷涂次数DM190中数值进行喷涂,自动开始喷涂之前DM190中的数值为0,点火装置完成一次点火,算做完成一次喷涂操作,用累加器完成喷涂次数的累计,当自动喷涂结束时,当前喷涂次数清零; [0034] carried out according to the spray gun to achieve frequency and numerical values ​​spraying DM190, DM190 value is automatically before starting spraying is 0, the ignition means to complete a firing, counted as complete a coating operation, spraying with a cumulative number of times the accumulator is completed, when the automatic At the end of spraying, spraying current number is cleared;

[0035]自动循环程序设计:喷涂循环与点火循环相同,点火次数可以等同视做喷涂循环次数,喷涂循环由预设喷涂次数进行限制,当达到喷涂次数预定值时,喷涂循环完成;喷涂参数设定以后,自动喷涂开始,每当完成一次喷涂,计数器累计一次喷涂次数,用当前喷涂次数DM190中的数值与预设次数DM170的数值进行比较,当前喷涂次数数值大于等于预设次数数值时,就完成一次自动循环喷涂过程。 [0035] The automatic programming cycle: Cycle and spraying the same ignition cycle, the ignition times can be viewed as equivalent to the number of spray cycles, spray coating cycle is limited by the predetermined number of times, when the number reaches a predetermined value spraying, spray cycle is completed; spray parameters provided after a given time, automatic spraying, whenever a complete coating, a spray counter accumulated number of times, the numerical value and compared with a preset number of current spray DM190 DM170 times, the current value is greater than the number of coating times equal to a preset value, it is automatic spraying process to complete a cycle.

[0036]进粉也实现循环操作,与点火循环设计方法一样,进粉循环与点火循环原理相同, 为使粉末在爆炸室中充分混合后才进行点火,进粉间隔时问略短于点火间隔时间; [0036] Powder feed cycle operation be achieved, with the ignition cycle design method of the same, and the same cycle of the powder into the firing cycle principle, the powder is mixed in the explosion chamber after ignition, the ignition asked slightly shorter than the interval into intervals powder time;

[0037] 操作流程:按照某型零件两点喷涂为例,对照爆炸喷涂工艺规程对试验件进行工艺试验要求,详细工艺步骤如下: [0037] flow: Part two o'clock in accordance with a certain type of coating, for example, the control procedure of the explosion spraying test pieces process test requirements, detailed process steps are as follows:
