Description
Technical field
The utility model relates to gear machining technology field more particularly to a kind of works for disc type gear forging processing
Dress.
Background technique
Gear drive is most widely used a kind of mechanical drive mode in modern various equipment.Its transmission is accurate, effect
Rate is high, compact-sized, reliable operation, and the service life is long.Wherein, gear transmits torque rotary speed by alternating load, and operating condition is severe, resultant force
It is high to learn performance requirement, to guarantee its reliable bearing capacity, blank requires forging.Forging can eliminate gear raw material and smelt
The defects of as cast condition generated in the process is loose optimizes heterogeneous microstructure.Simultaneously because the metallic fiber after forging on demand is walked
To improving stress-bearing capability.It forges rear mechanical performance and is better than the blank not forged.Die forging can also save material consumption, be suitble to criticize
Quantization production, is greatly improved stock utilization.
Disc type gear is most important structure type in gear, and when forging goes out inner hole, and metallic fiber trend can be made more to manage
Think, stress-bearing capability is stronger, substantially increases stock utilization.There is no center fixed when common forging tooling punching at present and punching the wad
The defects of position device causes hole and outer diameter to be easy bias, and inner hole is easy to produce extra gross weight, pulls, it can only take and reduce aperture
Eccentric error is made up, causes machining allowance more and processing difficulties, is costly and inefficient；In addition after punching with clamp by mold
And when blank flange, since vast majority of conventional forging press is without simple reliable and labour-saving tooling (or buying certain model
Forging press when could particular formulation hemmer, but purchase cost can be made to increase and volume is increased to product type and work-yard
Outer requirement), when product is heavier, cause man-hour manually hand-held clamp flange very painstaking, operating difficulties, large labor intensity and produce effect
Rate is low.
Utility model content
The utility model aim is to provide that a kind of punching can accurately feel relieved, stock utilization is high, turns over all over quick disk
Type gear forges tooling, to solve the above problems.
To achieve the above object, the utility model discloses a kind of disc type gear forge tooling, including be provided with inner hole with
Place the forging die of blank to be forged, for being forged to the blank to go out the formed punch of bore, to the formed punch
The gross weight punching for applying forging force and the locating cover to the formed punch guide-localization, the locating cover is set as can be living with the forging die
It is dynamic to be socketed, the pilot hole for formed punch guiding is provided on the locating cover.
Further, setting can stop with the positioning of the outer rim clearance fit of the forging die upper and lower ends on the locating cover
Mouthful.
Further, the formed punch is the tapered truncated cone-shaped structure of outer rim band
Further, the taper of the outer rim of the formed punch is 0.8 ° -1.5 °.
Further, the inner hole setting of the forging die is tapered.
Further, the taper of the inner hole is 0.8 ° -1.5 °.
Further, the outer diameter of the gross weight punching is less than or equal to the outer diameter of the small end of the formed punch.
It further, further include turnover bracket, the outer rim setting of the forging die is fluted, is provided on the turnover bracket
The crescent moon bearing portion of the forging die is overturn with the matching grooves.
Further, the end face of the forging die upper and lower ends is plane.
Compared with the prior art, the advantages of the utility model are:
The utility model is separated from each other by matched formed punch and gross weight punching, to make in punch process, without repeatedly
Formed punch is extracted, and then formed punch is avoided to extract required auxiliary clamping device and overcome frictional force bring between formed punch and blank
Energy loss.There is locating cover aligning punch when punching, punching is accurate.Meanwhile locating cover is also used to gross weight and goes out gross weight and punching in a state of excitement
Centralized positioning when head, directly enhances production efficiency and product quality.Further, the groove being arranged on forging die facilitates clamping to turn over
Turn, the bracket equipped with crescent moon bearing makes manually to overturn more convenient, laborsaving when forging die.
Below with reference to accompanying drawings, the utility model is described in further detail.

Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
As Figure 1-Figure 4, the utility model discloses a kind of disc type gear forge tooling, including be provided with inner hole 5 with
Place the forging die 1 of blank 6 to be forged, for being forged to blank 6 to go out the formed punch 2 of bore 7, be applied to formed punch 2
Add the gross weight punching 3 of forging force and the locating cover 4 to 2 guide-localization of formed punch, locating cover 4 is set as can be with 1 pivot bush unit of forging die, should
The pilot hole 8 being oriented to for formed punch 2 is provided on locating cover 4, wherein forging die 1 is the identical disc-shape of upper and lower side outer diameter, and
