Product Specifications
Product Details
Swing Pneumatic Clamp:The clamping force can be adjusted according to the material properties. During short-inch operation, the first set of clamps is automatically released, while the last set transfers the finished product onto the internal conveyor belt, ensuring the integrity of the finished parts.
P.K.O. and K.O. Structure:The P.K.O. and K.O. mechanisms are controlled by a digital servo motor and can be remotely adjusted for debugging. This system simplifies maintenance and ensures high-precision manufacturing of finished products.
Clutch: Equipped with a pneumatic clutch and pneumatic brake to avoid the starting current being generated repeatedly, making it convenient for parking and reversing, and improving the efficiency of mold debugging during installation.
Pneumatic clamp: It can be quickly adjusted centrally, used simply and stably, and the clamp can be freely changed with an exchangeable (optional) type.
With high-grade configuration, easy adjustment, and a centralized compressed-air system.
A powerful cut-off mechanism is directly driven by the crankshaft.
The high-precision main slider is connected with the rear-wing design to make its travel more stable and accurate. The QT600 material offers excellent wear and heat resistance. The inner bushing is thickened with a ZQSn10-1 copper sleeve to ensure precision and prolong service life.
Each station of the K.O. structure can be adjusted independently, and the last station can perform the reaming action by adjusting the cam position or replacing the cam. It is equipped with a safety pin for pressure checking.
By the cylinder-controlled pawl mechanism, the shaper lifts automatically, eliminating noise. The electromagnetic valve controls the cylinder feeding intermittently, allowing for larger product sizes and expanding the machine’s production range.
The straightening machine allows the material to enter and exit automatically. It features a horizontal alignment plane for easy cable installation. The self-feeding system loosens the wire to protect its surface from strain.
