Technical Field

The invention belongs to the technical field of machinery, and particularly relates to a hot heading die with a guide function.

Background

For a long time, when the head of a part is provided with an inner hole and has a corresponding position relation with the shape of the head of the part, the position degree of the inner shape of the head is difficult to ensure when the head of the part is formed by upsetting through a traditional hot upsetting die, so that the upsetting qualification rate of the product is low and the product quality is unstable; in addition, because this kind of hot upsetting mould of tradition need debug mould relative position repeatedly when upsetting to waste time influences hot upsetting efficiency.

Disclosure of Invention

The invention aims to overcome the defects and provide the hot heading die with the guide, which is used for heading the inner hole of the head of the part and has a position relation with the appearance of the head of the part, so that the hot heading qualification rate and the product quality of the product are improved, the die adjusting and testing time is shortened, and the hot heading processing efficiency of the part is improved.

The purpose of the invention and the main technical problem of solving the invention are realized by adopting the following technical scheme:

the invention discloses a hot heading die with a guide function, which is characterized in that a guide groove is formed in the die body; the outer surface of the hot upsetting male die is sleeved with a male die guide sleeve, the male die guide sleeve penetrates through the female die guide sleeve and is inserted into the hot upsetting female die, the outer surface of the hot upsetting female die is sleeved with a hot upsetting female die sleeve, the female die guide sleeve is connected with the hot upsetting female die sleeve through a positioning pin, die pads are arranged below the hot upsetting female die sleeve and the hot upsetting female die, and an ejector pin is inserted below the die pads.

The lower end of the hot heading male die is hexagonal, and the lower end head is conical.

The hot upsetting male die and the male die guide sleeve can move up and down in the female die guide sleeve and the hot upsetting female die sleeve.

The inside conical perforation that is provided with of hot heading die sleeve.

The outside of the hot upsetting female die is conical, the upper end of the middle of the hot upsetting female die is provided with a groove, and the lower end of the hot upsetting female die is provided with a hexagonal perforation.

The ejector rod can move up and down in the die pad.

Compared with the prior art, the invention has obvious beneficial effects; the technical scheme shows that: a male die guide sleeve is sleeved outside a hot upsetting male die, the male die guide sleeve penetrates through a female die guide sleeve to be inserted into a hot upsetting female die, a hot upsetting female die sleeve is sleeved outside the hot upsetting female die, the female die guide sleeve is connected with the hot upsetting female die sleeve through a positioning pin, die pads are arranged below the hot upsetting female die sleeve and the hot upsetting female die, and an ejector rod is inserted below the die pads. The die guide sleeve with the guide function fixes the relative positions of the die guide sleeve and the hot upsetting die sleeve by two positioning pins, so that the hot upsetting male die is matched with the die guide sleeve, then the male die guide sleeve is matched with the die guide sleeve to guide the position relation of the hot upsetting male die and the hot upsetting female die, and finally the relative positions of the hot upsetting male die and the hot upsetting female die are indirectly determined by the die guide sleeve, so that the relative positions of the inner shape and the outer shape of the part head are accurate during hot upsetting forming, and the position tolerance of the inner appearance of the part head and the consistency of the inner appearance of the part head are ensured. The upsetting quality of the parts is improved, the die adjusting and testing time is shortened, the hot upsetting machining efficiency of the parts is improved, the die guide sleeve and the upsetting die sleeve of the hot upsetting combined die are detachable, even if the hot upsetting die 7 or the hot upsetting male die fails, the die guide sleeve and the upsetting die sleeve can still be detached to be reused, the utilization rate of the die parts is improved, and the use cost of the die is reduced. In summary; the invention has the advantages that the inner hole of the head part of the part is upset, the relation between the inner hole and the appearance position of the head part is one, the hot-heading yield and the product quality of the product are improved, the time for adjusting the die and testing the die is shortened, and the hot-heading processing efficiency of the part is improved.
