Product performance of cold heading Nut machines:
The main body of high speed Multi-station Cold forging machine is made by high quality host casts and through second tempering treatment to ensure that whole machine can keep good and last longer.
All the moving parts are made by the best material and through best special technical treatment which can improve capability and ensure the machine life.
2.The key parts are made by numerical control machine and CNC to ensure the precision which can make the machine more stable and lower the noises.
3.We use famous hydraulic components and pneumatic components to ensure the stability of machine and the force lubrication system make every moving parts always running under a good lubrication environment.It is a good way to longer a machine's work life.
4.The major motor controlled by frequency converters and the driven system adopted pneumatic clutch device and pneumatic brake device to ensure the sensitivity and make the adjustment more easily and more quickly.
5.The electric control system adopted PLCS which can ensure the whole machine always in a normal way and auto deal with different kinds of failure.
6.The whole machine adopted seal completely design which can improve the safety and make the environment more cleanly.
Main Features of 5-station High Speed Cold Forging Machine, cold heading Nut machines:
Reversible nuts and fixed bolt clips that match with TGBF serial high speed multi-station parts cold forging 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.
Fig.04 is 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.
Fig.05 is 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.
Fig.06 is 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.
Perfomance of 5-station High Speed Cold Forging Machine, cold heading Nut machines:
MManipulator 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.
