Detailed Description
Referring to fig. 2-3, the present invention provides a technical solution:
a novel forging die for producing a shaft comprises an upper die 1 and a lower die 2, wherein the upper die 1 comprises an upper inner sleeve 12 and an upper outer sleeve 13, the upper inner sleeve 12 and the upper outer sleeve 13 are in interference fit, a groove 14 is formed in the position, higher than the bottom of the upper outer sleeve 13, of the bottom of the upper inner sleeve 12, a supporting block 15 is fixedly mounted at the top of the upper inner sleeve 12, the extending edge of the supporting block 15 abuts against the top surfaces of the upper inner sleeve 12 and the upper outer sleeve 13, and an upper die cavity 16 is formed in the inner cavity of the upper inner sleeve 12; the lower die 2 comprises a lower inner sleeve 22 and a lower outer sleeve 23, the lower inner sleeve 22 is in interference fit with the lower outer sleeve 23, a boss 24 is formed on the top of the lower inner sleeve 22 higher than the top of the lower outer sleeve 23, a support pillar 25 is fixedly mounted at the bottom of the lower inner sleeve 22, a base 26 is mounted at the bottom of the support pillar 25, the base 26 abuts against the bottom surfaces of the lower inner sleeve 22 and the lower outer sleeve 23, and a lower die cavity 27 is formed in an inner cavity of the lower inner sleeve 22; the boss 24 and recess 14 snap fit during forging. The outer surface of the upper inner sleeve 12 is a conical surface with a large lower part and a small upper part, and the inner surface of the upper outer sleeve 13 is also a conical surface with a large lower part and a small upper part, so that the inner sleeve and the outer sleeve are connected more tightly during forging.
