The utility model discloses a divide into the local mould of first local mould and second with the lower mould, first local mould and the separately processing of the local mould of second, rethread locking mechanism makes up into it one wholly when using, and its processing degree of difficulty that has reduced the long and thin die cavity of mould has reduced the manufacturing cost of mould to its convenience simple to use, practicality are strong.
Description
Technical field
The utility model relates to technical field of mold, particularly relates to the mould of a kind of gear shaft forging.
Background technology
Traditional elongated gear shaft is assembled into gear shaft by axle journal and gear key, in use, owing to axle journal is thin, easily turn round disconnected, and adopt integral material to process, amount of finish is big, material cost height, and when integral workblank adopts horizontal forging machine to forge, because gear external diameter is big, axle too carefully causes technical difficulty height, facility investment is big, mould cost height, forging cost height.
Practical novel content
The utility model mainly solves technical problem existing in prior art, thus provides a kind of mould processing gear shaft simple and convenient, that cost is low forging.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The mould of the gear shaft forging that the utility model provides; comprise upper die and lower die; on described counterdie is arranged under equipment backing plate; described counterdie comprises the first local mould stacked successively up and down and the 2nd local mould; the inside of described first local mould is provided with the first die cavity; the inside of described 2nd local mould is provided with the 2nd die cavity; described first die cavity and the 2nd die cavity match with the upper and lower of gear shaft respectively, and described first local mould and the 2nd local mould also mutually locked by a locking mechanism.
Further, described locking mechanism comprises pressing plate and counterdie backing plate, and described pressing plate is set in the outside surface of described first local mould, and described counterdie backing plate is set in the outside surface of described 2nd local mould, and described pressing plate and described counterdie backing plate are locked mutually by bolt.
Further, the bottom of described 2nd die cavity is also provided with a top material bar, and it is inner that described top material bar stretches to it from the bottom of described 2nd die cavity.
Further, the bottom of described 2nd local mould through backing plate under described equipment and extends downwards.
Further, the outside of described patrix is also arranged with guiding permanent sleeve, and the lower inside wall of described guiding permanent sleeve matches with the outer surface of upper of described first local mould.
The beneficial effects of the utility model are: by counterdie is divided into the first local mould and the 2nd local mould; first local mould and the 2nd local mould separate machined; it is combined into one more in use overall by locking mechanism; which reduce the difficulty of processing of the elongated die cavity of mould; reduce the manufacturing cost of mould, and it is easy to use, practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, it is briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the mould of gear shaft of the present utility model forging.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made more explicit defining.
Consult shown in Fig. 1, the mould of gear shaft of the present utility model forging, comprise patrix 1 and counterdie, on counterdie is arranged under equipment backing plate 2, counterdie comprises the first local mould 3 stacked successively up and down and the 2nd local mould 4, the inside of the first local mould 3 is provided with the first die cavity 5, the inside of the 2nd local mould 4 is provided with the 2nd die cavity 6, first die cavity 5 and the 2nd die cavity 6 upper and lower with gear shaft 11 match respectively, and the first local mould 3 and the 2nd local mould 4 are also locked mutually by a locking mechanism. The utility model by being divided into the first local mould 3 and the 2nd local mould 4 by counterdie; first local mould 3 and the 2nd local mould 4 separate machined; it is combined into one more in use overall by locking mechanism; which reduce the difficulty of processing of the elongated die cavity of mould; reduce the manufacturing cost of mould, and it is easy to use, practical. In the utility model; counterdie can also be divided into multiple local mould (such as 3 or 4 local moulds); then use after mutual stack combinations; the difficulty of processing of the elongated die cavity of mould can be reduced so further, but during combination, position precision can increasing and reduce along with local modulus amount.
Specifically, locking mechanism comprises pressing plate 7 and counterdie backing plate 8, and pressing plate 7 is set in the outside surface of the first local mould 3, and counterdie backing plate 8 is set in the outside surface of the 2nd local mould 4, and pressing plate 7 and counterdie backing plate 8 are locked mutually by bolt. Wherein, a step can be set at the outside surface of the first local mould 3, pressing plate 7 can be connected to the step upper surface of the first local mould 3, the outside surface of the 2nd local mould 4 can also arrange a step, counterdie backing plate 8 can be connected to the step lower surface of the 2nd local mould 4, thus realizes pressing plate 7 and the fast assembling-disassembling of counterdie backing plate 8.
Specifically, in order to the convenient bottom taking out gear shaft the 11, two die cavity 6 is also provided with a top material bar 9, it is inner that top material bar 9 stretches to it from the bottom of the 2nd die cavity 6. Preferably, the bottom of the 2nd local mould 6 through backing plate 2 under equipment and extends downwards, because mould whole height is higher, friction press mold assembling height dimension is little, below 2nd local mould 4 part is embedded under equipment backing plate 2, the problem of the die assembly undergage of equipment can be compensate for like this.
Specifically, the outside of patrix 1 is also arranged with guiding permanent sleeve 10, and the lower inside wall of guiding permanent sleeve 10 matches with the outer surface of upper of the first local mould 3, by the guide effect of the permanent sleeve 10 that leads, the quality of fit of patrix 1 and counterdie can be improved, it is to increase quality product.
Above, being only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim book limits.
