. Models apply air clutch brake with small starting current, allowing operation modes of "Inching", "Single Stroke" and "Continuous Running". The main sliding table can automatically stop at its rear position while operated under "Single Stroke" and "Continuous Running" modes, so as to obtain maximum space for adjustment.

. Enclosure cutting off die and knife deliver a clear and perfect cross section of blank for forming.

. The cut off roller is designed at the center of the cut off rod to avoid eccentric force occurred on the roller pin, so as to obtain high efficiency and stability of the cutting mechanism.

. Front knock-out (P.K.O.) actions coincide with back action of main sliding table, allowing the forged parts temporarily stay in the forming die, instead of being taken away by the punch.

. The machine main parts such as the bench, main sliding table etc has been treated for removing the residue stress after casting to avoid any deformation and keep stable precision of the machine in long term.


Advantages of Automatic cold forging and screw making machine, High speed Automatic Cold Heading Nail Machines
1.It can make the thead form of good quality.And it It has the high precision.
2.It can be used to process scerw and rebar.The rebar processed by the machine has the good overall mechanical.It can make the tensile strength increased by 20%-30%,the fatigue strength increased by 40%-60%,corrosion resistance increased by 50%-200%.Mechanical properties of rebar connector reached and more than international standards.
3.It works safe and reliable.It can works all day long,and can save steel and energy.
4.It adopt innovative design and advanced technology,alos it has the high precision and easy to operate.

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.

Company Advantages:
Ningbo Tenggong Precision Machinery Manufacture Co., Ltd. is subordinated to China Tenglong Stainless Steel Wire Group. In 2010, the company invests in a lot of advanced domestic and international metal plate processing equipments so as to ensure the strategic requirements of high starting point and high quality to the product R & D.
