Cold heading machine For making bolts and screws Guaranteeing precision and the curve smooth and sliding

Features:

1.Being equipped with air clutch with the advantage of low actuating current operating the former in 3 modes such as Inching, single stroke and continuous running. The main ram can stop at its rear position automatically, when the former is operated under single stroke and contuinuous running modes for guaranteeing the safety of die and leaving the biggest space for operation and adjustment.

2.Thanks to swing type pneumatic gripping mechanism, the gripping capacity is adjustable and clamping power is stable even at high working speed.

3.Pressing and feeding wire is actuated by pawl via the control of air cylinder. the pawl is fixed an auto-raise devuce, when the pawel goes back, it can raise, so the friction and noise can be eliminated. further more this device can prevent the ratchet running in reverse direction.

4.Wire cutting part is actuated by strong link-block system, the movement is stable and  reliable, as well as by using circular shears for assuming the kerf clear and neat.

5.Each station of rear knock out device can be adjusted individually, and the last station can realize the action of knocking out trimmed product via adjusting the location of cam or changing different cam.

6.Front knock out part moves simultaneously wtih the retreat movement of the main ram, for letting the product temporarily stay at mould plunger in order to prevent the plunger to be dragged away, then damage the product.

7.There is converter available in electrical system, so it is easy to run the former with stepless variable drive , PLC also is used for auomatically inspecting the working mode of the former with the functions of fault alarm anf fault display.

8.Both main and auxiliary rams, all are made of abrasion resistant alloy, and inside plates of the former are made of imported quench alloy steel for letting the former keep on long term's precision and stability, the service life of the die can be prolonged.

9.The principle parts such as body frame, main ram, main link lever etc. all are made of high-strengh material, however they are treated under strict casting technique, for instance, as stress relieving, in order to prevent deformation and machine rigidity can be promised as well as precision can be retained for long term.

10.Main components for each part and all are amchined by numerically-controlled machine tools, for guaranteeing precision and the curve smooth and sliding.
