Main structure and characteristics of cold heading die

1.Cutting die.Cutting die generally includes cutting A and A plate, and cutting IJ is installed in A plate L during use.In general, single and double cold heading machines and nut multi-station cold heading machines adopt the cutting method of "continuous cutting and feeding". After cutting off the ff material with the cutting knife, it is sent to the upsetting forging position by the cutter plate or clamp for upsetting.The clamp structure is installed on the cutting die, and the clamp has an appropriate round corner on the feeding side of the cutting IJ. When feeding, the textbook pushes the clamp along the round corner of the clamp with the aid of the feeding force.When cutting and feeding, the bad material is clamped by the force generated by the spring until the IIK material is pressed into a certain depth by the punch die and the cutting knife recede.

 After cutting, the material is received by the transfer clamp waiting at the cutting die and then transferred to the upsetting die.It is important to note that in the upsetting specification of the workpiece, in order to avoid the impact of the die and the cutting knife,cutting material in the non-shear side of the oblique.Some need to reduce the thickness of the part of the knife body.The back end of the cutter is made into a 300 bevel for fastening with the knife plate.

 2.Cutting rod die.Cutting rod die is generally made up of cutting die, die sleeve and die pad.Cutting die and die sleeve adopt the way of interference fit, do not allow loose phenomenon, in order to work process can withstand the friction of feeding and cutting knife cutting the lateral pressure of the wire.
