專利型直壓式打刀缸之特性:
Unclamping Cylinder Features:

1).打刀缸附加專利型液位檢知系統,此系統可有效防止或避免打刀換刀不確實之危險。眾所週知,一般之打刀缸為氣液壓系統混合體,利用活塞之大小面積比轉換為出力比值及吐出量進而得到增壓行程(即直壓式增壓缸之行程)。然而在工具機操作一段時間後鮮少有操作者會時常的去單獨特別注意打刀缸剩餘油量,但是當剩餘油量不足時即有可能產生不可預期或出人意料之損失。歐境之液位檢知系統可有效防止或避免打刀換刀不確實之危險。

The Unclamping Cylinder is equipped with patented Oil Level Detecting System, the System can effectively prevent from dangers of incomplete tool Clamping / Unclamping :
As aware, ordinary Unclamping Cylinders are combinations of pneumatic and hydraulic systems. The Output Ratio and Discharge Volume, which get the Pressuring Stroke (ie the stroke of the Direct Operated Power Unit Cylinder), are converted by the area ratio of the Piston. However, few of the operators will pay attention to the oil level of the Unclamping Cylinder on the machine tools after a period of time of operation. Unexpected accident might occur when the oil level of the Unclamping Cylinder is insufficient. DETER Oil Level Detecting System can effectively figure out the low oil level, this can prevent from danger of incomplete Clamping / Unclamping.

2).附加專利型可調機械式主軸吹氣機構,可確保退刀完成後才吹氣,有效去除原打刀與吹氣同步所產生於拉刀桿內氣障之影響(刀桿未打下前,同步吹氣所產生於拉刀桿內油水氣的囤積,打刀後因拉刀桿囤積氣壓產生刀柄對取刀臂的衝擊,造成取刀臂之側向力負載,油水氣之噴濺造成主軸壽命之降低等等問題).

The Unclamping Cylinder is equipped with patented Mechanical Adjustable Spindle Air Blasting System, it makes sure of the air blasting to be actuated right after tool unclamping.
 In conventional design, the actuations for tool unclamping and air blasting are occurred simultaneously, this will cause to the Air Barrier phenomenon in the draw bar. The Air Barrier phenomenon is that, when the tool unclamping and air blasting actuate simultaneously, the air blasting will cause to the oil and coolant moisture accumulation in the drawbar during pushing down of the Unclamping Cylinder, then after pushing down, the pressure accumulation will cause tool holder to impact on the tool arm, the impact cause to increasing of side-force load toward the tool arm. In the meantime, the spitting of oil and coolant moisture will reduce the lifespan of the spindle.

3).缸體頂端附有頂刀量之微調,另打刀端附有頂刀安全距離之微調,在在顯示此打刀缸在調整頂刀量及安全距離之方便性及確實性.

A Micro-regulator Mechanism for the cylinder stretching length is installed on top of the cylinder body. Another Micro-regulator Mechanism for pushing distance regulation is located at the contacting end. Both mechanisms on the Unclamping Cylinder provide high accuracy and convenience for the device regulation.

4).專利之倍力設計,讓打刀缸佔用最小空間,彰顯最大的出力.

The patented Multiple-Force design on the Unclamping Cylinder can hugely reduce the space occupation and increase the maximum output.
