Abstract
The utility model discloses a screw nut forging die comprising a male die and a female die, which are engaged with each other, wherein the female die comprises a material beating rod which is arranged inside a die hole; the material beating rod is provided with a head part for forging a rear hole face of a screw nut; and the distance from the end surface of the male die to the end surface of the head part of the material beating rod, at the site of minimum running stroke of the female die and the male die, is set as d1. The utility model is improved as follows: the head part of the material beating rod is provided with a material ejecting end which is larger than the head part, the material ejecting end and the head part form a step, a protrusion extends from the male die for forging a screw nut inner bore, and the length of the protrusion is not more than d1. By arranging the material ejecting end for material discharge at the head part of the material beating rod, the male die can be extensively designed, even the distance from the male die to the end surface of the head part of the material beating rod can be zero, and the screw nut inner bore is forged to a desired length or penetrated. Therefore, the procedures of machining and drilling are omitted.
Description
Technical field
The utility model relates to the nut forge mould.
Background technology
Forge nut and raw material need be forged into base, punch and the die interaction forging and pressing of existing technology by cooperatively interacting, referring to Fig. 1, weakness punch 1 end face of die 2 and punch 1 operation stroke and knockout rod 3 head end 32 are apart from being made as d1, d1 is the surplus of being stayed between knockout rod 2 and the punch, blank is punched preventing, be difficult to from die, take out blank.Also need to carry out machined behind the blank forging, boring etc., technology is comparatively complicated.
Summary of the invention
The utility model provides a kind of nut production technology of can simplifying for solving the problem that prior art in use exists, and saves the nut forge mould of production link.
The technical scheme that the utility model solves existing issue is: a kind of nut forge mould, comprise the punch, the die that cooperatively interact, described die comprises the knockout rod that is arranged in the nib, described knockout rod is provided with the head that forges nut metapore face, the weakness punch end face of die and punch operation stroke and knockout rod head end are apart from being made as d1, as improvement, the head of described knockout rod is provided with greater than head liftout end, described liftout end and head constitute ladder, the punch that forges nut inner hole is extended with boss, and described land length is not more than d1.
As improvement, described liftout end is not less than the nut back end face.
As improvement, transition has the inclined-plane between liftout end and the head.
The utility model compared with prior art, its beneficial effect is by be provided for the liftout end of discharging at the knockout rod head, punch can be prolonged design, even punch can be made as 0 with knockout rod head end distance, nut inner hole can be forged to need length or punch.And then save machined, boring supervisor.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the structural representation of the utility model die.
The specific embodiment
Referring to Fig. 2-3, the implementation case comprises punch 1, the die 2 that cooperatively interacts, die 2 comprises the knockout rod 3 that is arranged in the nib 21, knockout rod 3 is provided with the head 31 that forges nut 5 metapore faces 51, weakness punch 1 end face of die 2 and punch 1 operation stroke is made as d1 with knockout rod 3 head end 32 distances, and the head 31 of knockout rod 3 is provided with greater than head 31 liftout ends 33, liftout end 33 and head 31 formation ladders, the punch 1 that forges nut 5 endoporus is extended with boss 4, and boss 4 length are not more than d1.
For the ease of discharging, as preferably, liftout end 33 is not less than nut 5 rear end faces 52.Transition has the inclined-plane between liftout end 33 and the head 31.
Claims (3)
1. nut forge mould, comprise the punch, the die that cooperatively interact, described die comprises the knockout rod that is arranged in the nib, described knockout rod is provided with the head that forges nut metapore face, the weakness punch end face of die and punch operation stroke and knockout rod head end are apart from being made as d1, it is characterized in that: the head of described knockout rod is provided with greater than head liftout end, described liftout end and head constitute ladder, the punch that forges nut inner hole is extended with boss, and described land length is not more than d1.
