The modes of three road punching press undergauges realize and formed pin semi-finished product C.Specifically, first is used for pin semi-finished product B
Upper opening portion carry out undergauge, the position diameter of top 200mm length is narrowed down into 3.5mm, at the same time, pin semi-finished product
B overall length is changed into 30.8mm；Second is for pin semi-finished product B upper opening portion to be carried out into undergauge again, by top 21.5mm
The position diameter of length narrows down to 3.1mm, at the same time, and pin semi-finished product B overall length is changed into 32.0mm；3rd road is to be used to incite somebody to action
Pin semi-finished product B upper opening portion carries out undergauge again, and the position diameter of top 22.5mm length is narrowed down into 2.73mm, same with this
When, pin semi-finished product B overall length is changed into 33.0mm, and finally obtains pin semi-finished product C.
Step E reducing annealing：It is to carry out reducing annealing to one section of pin semi-finished product C adjacent openings, and
Obtain pin semi-finished product D.Specifically, pin semi-finished product C is laterally first folded in automatic lathe chuck, and by automatic lathe chuck
It is driven so that the rotation of its high speed, then passes through draw set that is being set with pin semi-finished product C concentric shafts and can sliding laterally
Head to carry out friction and Extrusion to pin semi-finished product C opening portion, specifically with continuous three friction and Extrusions, to realize to pin half
The crowded compressed shape of finished product C opening portions, wherein extruding depth is 6mm, and the diameter of extruded parts is narrowed down to from 2.73mm
2.6mm, and form pin semi-finished product D；It is appreciated that after the pin of rotation half is contacted into C with draw pullover at a high speed, it connects
Contact portion can make it soften because of frictional heat, then can reach contracting shape most under the hardness extruding of draw pullover transverse shifting
Whole purpose, and obtain pin semi-finished product D.
Step F reaming flange：It is the opening endoporus that pin semi-finished product D is inserted with thimble, with to tip cutting pin semi-finished product D's
Open end carries out reaming flange, and obtains final pin body 10.Specifically inserted using the thimble of cone by automatic
Lathe dog clamping and the pin semi-finished product D of high speed rotation driving opening endoporus, specifically carry out continuous three interactions, tool
Body can work as after its flange reaches defined size exits thimble again, pin semi-finished product D open end is reached reaming flange
Effect, finally obtained the pin body 10 required for us, that is, obtain reducing cylindrical pin.
It is appreciated that preparing reducing cylindrical pin using the preparation method of the above, it only needs to adjust each step
In corresponding site of action, and required regulation size quantity, you can the reducing cylinder for preparing different size is inserted
Pin, to meet different use demands, just differ one has been illustrated herein.
