Specific embodiment
Embodiment 1
In the present embodiment, a kind of punching die for forged hub is disclosed, the mold includes centre punch
(1-1), small formed punch (1-2), bolt (3), small mandril (4), column (5), central ejector rod (6), pallet (7), are fixed at lower die (2)
Bolt (8), main mandril (9), discharging pressing plate (10), discharging spring (11), guide blot (12), backing plate (13), upper big plate (14),
Guide post (15) and guide sleeve (16), it is characterised in that: backing plate (13), backing plate are equipped with by bolt below the upper big plate (14)
(13) lower section is fixed with guide blot (12), and guide blot (12) outer sheath is equipped with discharging spring (11)；The backing plate (13)
Lower central part is equipped with centre punch (1-1), and periphery is equipped with small formed punch (1-2), the centre punch (1-1) and small
Formed punch (1-2) is provided towards the blank (1) of lower section；The main mandril (9) is mounted on lower methods, rack, and pallet (7) passes through
Fixing bolt (8) is mounted on main mandril (9), and the centre punch (1-1) and small formed punch (1-2) are set as working as Guan Bi mould
When contact pallet (7)；It is also equipped on the lower methods, rack column (5), column (5) top is mounted with down by bolt (3)
Mould (2) aperture and is equipped with central ejector rod (6) at center in lower die (2), and periphery is equipped with small mandril (4)；In the backing plate
(13) guide sleeve (16) are installed on lower surface, on lower methods, rack guide post (15) are installed on corresponding position, and be set as
Guide sleeve (16) and guide post (15) matching.The discharging spring (11) is set as being compressed to the 65% of its raw footage when the die is closed, and
