rear knock-out mechanisms. Rear knock-out mechanism of various stations can respectively and independently adjusted. Last station can fulfill edge-cutting or knock-out actions through adjusting or changing cam. Before being kicked out, dead-point position of all models keeps the same. Some models can choose to hand-wheel type or CNC type rear knock-out threaded pipe adjusting mechanism.
punch knock-out mechanism of TGBF serial model.. Punch knock-out coincides with back action of machine slider. After the work-piece is shaped, it stays in the mould and then being kicked out by rear knock-out mechanism. It avoids being taken away by the punch and then get deformed. Various stations of front knock-out positions can be independently adjusted. All the front lead-out mechanisms have knock-out force over-load protection devices.
electric feeding mechanisms. In return stroke, pawl can be automatically raised by air cylinder and be separated form ratchet wheel. It not only removes friction and noise, but also prevents ratchet wheel from reversal operation.
Main Features:
Reversible nuts and fixed bolt clips that match with TGBF serial multi-station parts forming machine.
Transfer conveyance of rotary swing mode and transfer force of adjustable pneumatic mode ensures stable and reliable work-piece conveyance and high speed operation of the machine. The first station clip can automatically loose short dimension feeding, stop and alarm.
Reciprocating movement of clipping table and opening/closing actions of the clip are both driven by a joint intermediate shaft to ensure the coordinated actions.1.Manipulator with rotary swing clip feed means and pneumatic clamping force, is not only stable but also can adjust the pressure according to different products avoid crushing the products.
2.The rear knock out mechanism can be individually adjusted with front dead point in the same position.3. Feeding system of ratchet pawl wheel is stable, reliable and convenient to adjust.
4. Cross movement of the machine driven by double-cam above the shaft makes it easy to adjust the operating compatibility of the machine.
5. The cams in various positions are calculated and designed by the computer, and then machined and manufactured by CNC machine tool to ensure smooth and precise curves.
6. Side plates apply imported quenched high-carbon alloy steel SKS to maintain stable precision of main sliding table in long term.
7. A PLC controlled safety checking system can automatically detect the performance of key system and display of any abnormality.
8. Imported inverter is equipped for easy adjustment of stepless output speed.
9. As an optional, CNC system of "man-machine interface" can be equipped to automatically adjust the dimension of rear knock-out threaded pipe, stop position and feeding length, greatly saves mould renewal and adjusting time. With a memory capacity of 99 digital modules, it is suitable for fast change over of moulds.
