自動沖床下死點監視裝置
Automatic Press Bottom Dead Point Monitoring Device
NEW SELBER BX RM-2402、2404
RM2402的優勢：
1)RM2402的分辨率是0.5um，表示可以察覺極小的變化值。越是薄的材料，越需要高分辨率。正常的下死點變位差是監視沖床下壓后的距離。軟性材料以及薄質材料，如有跳屑、小雜物，在沖壓最后會被壓扁在一起，分辨度不夠高，或許無法察覺其差異。
2)RM2402多了一個功能選擇(第一彈跳變位差監視模式)，提前檢查接觸時距離差。當材料，或是模具有異物時，在接觸的時候，便可檢查出來，可減少模具受損。同時，防止生產出壓扁變形的不良產品。
3)對應沖床最高轉速=4000min(spm)。
4)對應沖床最小沖程高度=4mm。
5)該產品穩定性良好，客戶抱怨極少。
簡介：
It detects slugs coming up by measuring the bottom dead point position of stripper plate.
Since it will catch up with 4000 rpm as maximum, it is good for high speed precision press machine to detect slug coming up.
Characteristics
It covers as small as 4mm stroke length of a press machine. (It was 8mm for the conventional unit.) It has sensor compensation function.
Similar sensor s made by other makers are also applicable.
•It is miniaturized in a half size of the conventional unit (MB, MX 2sets).
•It enables high accuracy detection. Resolution : 0.5μm
•It has first bound detection function. (First bound automatic search function.)
•The brightness of display is about 4 times brighter than conventional unit. It keeps clear view from a distance.
•Error lamp will blink when error is detected.
•Maximum 4-channel detection is available by installing an additional option unit (RM-2502).
Detection Method
1. Bottom Dead Center Mode (B.D.C.)
If a slug is caught in the die with spring loaded stripper, the stripper position will be changed. The slug is detected by the displacement of the stripper at B.D.C.
2. 1st Bound Mode
When the die has extra high spring force or is of bottoming construction, the slug may be almost entirely crushed, thus it may be too difficult to detect the stripper displacement. In such a case, you can use 1st Bound Mode, where the sensor highlights the stripper displacement when the stripper touches the slug (before it is crushed).
Setting of Monitoring Value
BX unit detects the difference of B.D.C. data between the current and the receding shots as the deviation (B.D.C. displacement). Setting of monitoring value is setting of the allowable limit of displacement.
