Introduction This machine adopts steel plate welded body structure, with reliable strength and stiffness; clutch with wet friction clutch, so that a smooth clutch, transmission torque, and thus adapt to the rapid mode of operation; wet track surface type block, connecting rod big end of rolling bearing, resulting in greatly improved precision machine, mechanical clamp feeding device feeding mechanism, to ensure high-speed state machine in the feed accuracy. From the motor to the flywheel from the crankshaft to the feeding device and were used to flat belt timing belt transmission, improve transmission efficiency and simplify the structure. Electric variable frequency control, easy to adjust the slider trips; and programmable logic controller, the system is simple, stable and reliable. The machine has the above characteristics, it has the operation, adjustment is simple and convenient, and reliability, high precision machine to improve its cost performance and display a good technical and economic benefits. Model price (RMB): J21G-25A (18), J21G-45 (21), J21G-60 (25) Note: The price is not feeding device prices, according to user requirements feed specifications, roll-feed price separately.
