Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown in Figures 1 to 9, the processing method that pressing-riveting bolt can be extended and rub frid service life with the hands of the present embodiment, including
Following steps,
One, with the first die body by part idiosome pier at the first body part 4 with part original shape；
Two, with the second die body by first 4 pier of body part at the adult part 41 with External Shape；
Three, with third die body by adult part 41 to lead neck 42 upset；
Four, required bolt slot is formed with the outer surface that neck top is led in stranding frid mill stranding；
Five, with screw thread is rubbed on the thread segment of screw plate part made of the 4th step, process operation is completed.
In step 3, it is upset after lead neck diameter D1 be 8.1~8.3mm.After upset lead neck depth degree L be 1.7~
1.9mm.The junction for leading neck 42 and part thread segment after upset is formed with chamfering structure, and the section angle a of the chamfering is
63~67 °.
Third die body includes third punch die and third die holder 3, and the third punch die is connected with third punch die driving mechanism,
The third punch die is driven by third punch die driving mechanism and opposite third die holder 3 moves up and down, the top surface of the third die holder 3
On be provided with top surface cavity, formation die core 33 is provided in the top surface cavity, the middle part of the formation die core 33 is provided with
Three forming cavities, the third forming cavity are divided into third upper cavity 31 and third lower chamber 32, the diameter of the third upper cavity 31
It is adapted with the neck diameter D1 that leads after upset, the diameter D2 of third lower chamber is adapted with the thread segment diameter of adult part 41.
The fillet for preventing part from colliding with is provided on the top surface of the formation die core 33 where third forming cavity.The diameter D3 of formation die core
Greater than the diameter D4 of adult part, the diameter D3 of the formation die core is 20~24mm.The diameter D2 of the third lower chamber is 7
~7.2mm.
First die body includes the first punch die 1 and the first die holder 11, and first punch die 1 is connected with the first punch die driving mechanism
It connects, first punch die 1 is driven by the first punch die driving mechanism and opposite first die holder 11 moves up and down, first die holder 11
Top surface on be provided with the first forming cavity 12, being provided on the bottom surface of the first punch die 1 can punching corresponding with the first forming cavity 12
