High efficiency bolt thread making machines, screw making machine
1.Hydraulic power,
2.Safety,
3.Electronic controlling

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 of High efficiency bolt thread making machines, screw making machine:

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.
