为适应日常较多的金相试样镶嵌的需要,我们自制了一台自动镶嵌机(图1)。使用它的优点是省力,速度稍快一点,环境干净。本机主要的性能数据如下: 1.热电丝220V800w; 2.加热时间:初始工作需17分钟左右,持续工作每次3～4分钟; 3.顶杆升降速度:6.2mm/秒;4.加粉时间:1.5秒;5.水冷时间:50秒左右;6.吹风时间:4秒;7.镶样时间:初始工作每只18分钟左右,连续工作每只4～5分钟。操作过程是这样的:合上总电源,控温仪给出指示温度,于顶杆面上放上试样,按下降按钮,顶杆便自动下降,待胶木粉自动加好,放入上模即可。待试样镶好时会响铃报告。机械结构见图2。
In order to meet the daily needs of more metallographic specimen inlay, we made a self-mounted mosaic machine (Figure 1). The advantage of using it is labor-saving, slightly faster, clean environment. The main performance data of the machine are as follows: 1. Thermoelectric wire 220V800w; 2. Heating time: initial work takes about 17 minutes, continuing work for 3 ~ 4 minutes each time; 3. Jacks lifting speed: 6.2mm / sec; Powder time: 1.5 seconds; 5. water cooling time: about 50 seconds; 6. hair time: 4 seconds; 7. Mounting time: initial work of about 18 minutes each, continuous work for each 4 to 5 minutes. The operation is like this: Close the total power supply, temperature controller gives the indicated temperature, put a sample on the ejector face, press the drop button, ejector will automatically drop until the bakelite powder automatically added good, into the mold Can be. Beeps when the sample is in place. Mechanical structure shown in Figure 2.
