Abstract

The utility model discloses a forging and pressing die for molding a hexagonal nut, which comprises an upper die mechanism and a lower die mechanism, wherein the upper die mechanism consists of an upper die plate and an upper die fixing plate, and a punch is arranged on the upper die fixing plate; and the lower die mechanism consists of a lower die plate and a lower die fixing plate, a lower die is arranged on the lower die fixing plate, an upper die base plate is arranged between the upper die plate and the upper die fixing plate, the upper die base plate has an upward opening and is hollow, a connecting block is arranged in a cavity of the upper die base plate, an ejector rod on the lower surface of the connecting block passes through the upper die base plate and the upper die fixing plate and is connected to a scraper plate, the end part of the punch passes through the scraper plate and is arranged in a suspension manner, a knockout rod on the upper surface of the connecting block passes through the upper die plate and a die handle on the upper die plate; and an inner hexagonal die cavity is arranged in the position where the middle part of the lower die corresponds to the punch. In the utility model, a circular-section copper rod with the same diameter as the inner hexagonal die cavity is placed in the inner hexagonal die cavity of the lower die and is forged and pressed to form a blank for the hexagonal nut, and then the blank is manufactured by CNC, therefore, the cutting number is reduced, the raw material is saved, and the production cost is reduced.

Description

Hex nut moulding forging die
Technical field
The utility model belongs to the forging equipment field, specifically relates to a kind of hex nut moulding forging die.
Background technology
In the prior art, the pipe fitting of air-conditioning connects need use a lot of hex nuts, these hex nuts machine after needing copper rod to be forged into base again, because hex nut multi-size, use existing hexagonal cross section copper rod to forge into the words that machine into hex nut behind the base again, cutting output is bigger, and waste is serious, the production cost height.And machine again after forging into base by the suitable circular section copper rod of diameter, can reduce cutting output, save material, reduce production costs.But existing forge die can not be applicable to and use the circular section copper rod to forge into the blank of hex nut.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of hex nut moulding forging die is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of hex nut moulding forging die, constitute by last mold mechanism and following mold mechanism, wherein go up mold mechanism and comprise cope match-plate pattern and upper mould fixed plate, drift is set on the upper mould fixed plate, following mold mechanism structure comprises lower bolster and counterdie fixed head, on the counterdie fixed head counterdie is set, between described cope match-plate pattern and the upper mould fixed plate upper die plate is set, upper die plate is opening hollow form up, in the cavity of upper die plate contiguous block is set, push rod below the contiguous block passes upper die plate and upper mould fixed plate is connected on the material scraping plate, the unsettled setting of material scraping plate is passed in the end of described drift, and the knockout rod above the contiguous block passes the die shank on cope match-plate pattern and the cope match-plate pattern; Hexagonal die cavity in the position of the corresponding drift in the middle part of described counterdie is provided with.
As preferably, a side of described drift is provided with guide pillar on upper mould fixed plate, and the unsettled setting of material scraping plate is passed in the end of guide pillar.
As preferably, between described material scraping plate and the upper die plate extension spring is set, extension spring is hung on the screw rod in the material scraping plate and the upper die plate outside.
As preferably, the push rod below the described contiguous block is provided with 3-5, around the uniform setting of drift.
As preferably, the interior hexagonal die cavity bottom of described counterdie is provided with steam vent, and steam vent is communicated to the counterdie backing plate between lower bolster and the counterdie fixed head.
The utility model drives die shank by power set, knockout rod is established material scraping plate in order to discharging through the push rod top, at the mid-suitable circular section copper rod in footpath that straightens of the interior hexagonal die cavity of counterdie, through forging into the blank of hex nut, machine again, can reduce cutting output, save material, reduce production costs, the utlity model has characteristics such as simple in structure, reasonable in design.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, the utility model is made of last mold mechanism and following mold mechanism, wherein go up mold mechanism and comprise cope match-plate pattern 2 and upper mould fixed plate 5, drift 6 is set on the upper mould fixed plate 5, between cope match-plate pattern 2 and the upper mould fixed plate 5 upper die plate 4 is set, upper die plate 4 is opening hollow form up, contiguous block 19 is set in the cavity of upper die plate 4, push rod 8 below the contiguous block 19 passes upper die plate 4 and upper mould fixed plate 5 is connected on the material scraping plate 7, push rod 8 below the contiguous block 19 is provided with 3-5, around drift 6 uniform settings, material scraping plate 7 unsettled settings are passed in the end of described drift 6, one side of described drift 6, guide pillar 10 is set on upper mould fixed plate 5, and material scraping plate 7 unsettled settings are passed in the end of guide pillar 10, between material scraping plate 7 and the upper die plate 4 extension spring 9 are set, extension spring 9 is hung on the screw rod 18 in the material scraping plate 7 and upper die plate 4 outsides, and the knockout rods 3 above the contiguous block 19 pass the die shank 1 on cope match-plate pattern 2 and the cope match-plate pattern 2; Following mold mechanism structure comprises lower bolster 16 and counterdie fixed head 13, and counterdie 11 is set on the counterdie fixed head 13; Hexagonal die cavity 12 in the position of the corresponding drift 6 in the middle part of described counterdie 11 is provided with, interior hexagonal die cavity 12 bottoms of counterdie 11 are provided with steam vent 14, and steam vent 14 is communicated to the counterdie backing plate 15 between lower bolster 16 and the counterdie fixed head 13.
During matched moulds, at the mid-suitable circular section copper rod in footpath that straightens of the interior hexagonal die cavity of counterdie, power set drive die shank, and die shank presses down cope match-plate pattern and upper mould fixed plate drives the copper rod in the hexagonal die cavity in the drift forging and pressing counterdie, produces the blank of hex nut; During the demoulding, power set rise, and drift breaks away from press forging, and this moment, material scraping plate was withstood the hex nut blank downwards by push rod, so that drift breaks away from the hex nut blank smoothly, and wiped the particle on the drift off.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
