Fig. 1 is a kind of structural representation of out star wheel warm forging of traditional handicraft forging;
Fig. 2 is the utility model out star wheel warm forging technique process chart in one embodiment;
Fig. 3 is the product shaping procedure chart that the utility model utilizes mould to forge, wherein Fig. 3 (a) is the shape of product obtaining after blanking procedure, Fig. 3 (b) is for just squeezing the shape of the product obtaining after operation, the shape of product of Fig. 3 (c) for obtaining after jumping-up operation, Fig. 3 (d) is the anti-shape of product obtaining after operation that squeezes;
Fig. 4 is the structural representation that the utility model carries out the heading die of jumping-up operation.
The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Alleged " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the utility model herein.Different local in this manual " in one embodiment " that occur not all refer to same embodiment, neither be independent or the embodiment mutually exclusive with other embodiment optionally.
Refer to shown in Fig. 2, it is the utility model out star wheel warm forging technique process chart in one embodiment.Refer to shown in Fig. 3 the product shaping procedure chart that it utilizes mould to forge for the utility model.Process chart described in figure comprises the steps.
Step 210: blanking
Out star wheel is strict to the chemical composition of steel, inside and outside quality or dimension precision requirement.Require to select suitable bar, adjust cutting length, by Weight control in predefined scope.The shape of product of Fig. 3 (a) for obtaining after blanking procedure.
Step 220: just crowded
Described just squeezing is that the solid cylindrical bar after described blanking procedure is put into the blank that mould is just squeezing to obtain having large end and small end.Fig. 3 (b) is for just squeezing the shape of the product obtaining after operation.
Step 230: jumping-up
Described jumping-up is to align blank after squeezing to carry out two ends jumping-up and have protuberance to form large end, and small end has cylindrical blank.The shape of product of Fig. 3 (c) for obtaining after jumping-up operation.In this embodiment, the centre at the large end place of the blank that described jumping-up operation forms has protuberance 301, and described protuberance 301 is circular-arc.
Step 240: instead squeeze
Described anti-to squeeze be to described blanking, just squeeze, the blank after jumping-up carries out backward extrusion and has inner chamber 302 to form large end, and small end has columned forging stock.Fig. 3 (d) is the anti-shape of product obtaining after operation that squeezes.The 304Wu Ta angle, R angle of described inner chamber sidepiece, and overlap 303 abundances.
After described step 210 blanking procedure, step 220 also comprises ball blast, coating and heating process before just squeezing operation.
Refer to shown in Fig. 4, it carries out the structural representation of the heading die of jumping-up operation for the utility model.Heading die described in figure adopts simple mould structure, and it is for to blanking, and the blank after just squeezing carries out jumping-up and has protuberance to obtain large end, and small end has cylindrical blank.Described heading die mainly comprises jumping-up drift 401 and jumping-up die 402.The head 4011 of described jumping-up drift 401 is bowl configurations, in described jumping-up die, is provided with core rod, and described jumping-up die 402 is formed with matrix cavity.When adopting heading die to carry out jumping-up operation, the protuberance at the large end place of the blank that the bowl configurations of described jumping-up drift 401 heads 4011 and described jumping-up operation form matches.In this embodiment, shape and the size of the pit of described jumping-up drift 401 heads 4011 are not limited, as long as guarantee can have enough materials to flow to outside overlap when anti-squeezing, inner chamber is sufficient, there will not be the not enough and R arc of the overlap large phenomenon in angle of collapsing.
The process of utilizing heading die to carry out jumping-up is: the blank that described step 220 is just being squeezed after operation is put into heading die, jumping-up drift 401 moves downward, jumping-up drift 401 heads 4011 contact with the large end of described blank, described jumping-up drift 401 moves downward, the head 4011 of described jumping-up drift 401 is fitted the large end of blank completely until large end place forms protuberance, now, the small end of blank forms cylindric in described core rod 403, after jumping-up operation completes, described jumping-up drift 401 backhauls, adopt stripping attachment 404 by 405 jack-up of the blank after jumping-up, jumping-up finishes, obtain large end and there is protuberance, small end has cylindrical blank 405 (referring to Fig. 3 (c)).To carry out next step, instead squeeze operation.
The utility model is by the pit shape of jumping-up drift, while making jumping-up, there are enough materials for making clothes to protrude, can be so that the large end place of the blank forming in jumping-up operation be formed with the projection of a radian, and then make instead can increase material in pushing through journey follow-up, can better contact with the anti-drift that squeezes, make the anti-crowded drift of material for making clothes parcel that inner chamber is sufficient, the angle that prevents from collapsing becomes large and overlap is not enough; The more traditional jumping-up drift of jumping-up drift of the present utility model is short, has not only saved material, and has reduced cost.
Above-mentioned explanation has fully disclosed the specific embodiment of the present utility model.It is pointed out that being familiar with any change that person skilled in art does the specific embodiment of the present utility model does not all depart from the scope of claims of the present utility model.Correspondingly, the scope of claim of the present utility model is also not limited only to previous embodiment.
