Because the gross weight that generates during finish-forging is thin and discontinuous, in the side cut process, checking-valve body is difficult to keep out the deformation force that clipping press applies, thereby causes the guiding rib distortion.Therefore, after side cut, also need carry out shaping to it handles.
Therefore, to the characteristics of this stop valve, adopt following flow usually: blanking-ejection-blocking-go gross weight-finish-forging-side cut-shaping-subsequent treatment.Because the rigidity of guiding rib is relatively poor, when side cut and punching, be easy to generate torsional deformation, need carry out shaping and handle, manufacturing efficiency is lower, and forging die is shorter working life.The arts demand blocking that this forging adopted, finish-forging two cover forging dies, frock drop into that expense is big, and it is too much to heat number of times aborning simultaneously, occurs overheated, burn-off phenomenon easily, and the manufacture cycle is long, efficient is low, cost is high, the competitiveness of product in market a little less than.
The model utility content
The goal of the invention of the utility model is: the problem to above-mentioned existence, a kind of checking-valve body is provided, and the utility model is through optimizing the structure of checking-valve body; Gross weight between the guiding rib is made into Sloping Hearth; Thereby it is protruding to the ear shape to help metal flow, and can hold the metal of redundance, thus effective shortened process and manufacture cycle; Improve utilization ratio of raw materials, reduce production costs.
The technological scheme that the utility model adopts is following:
A kind of checking-valve body comprises that the guiding rib of Y valve body, valve gap, connection Y valve body and valve gap, the ear shape that is arranged on the Y valve body are protruding, connects through the Sloping Hearth gross weight between the said guiding rib.
Said Sloping Hearth gross weight is 3 °-5 ° with respect to the gradient of vertical direction.
As preferably, said Sloping Hearth gross weight is 5 ° with respect to the gradient of vertical direction.
Owing to no matter adopt which kind of gross weight structure in the checking-valve body, the user adopts the mode of line cutting to remove gross weight in the post-production process, and the change of gross weight structure and the increase of thickness do not influence follow-up machining.Therefore; The utility model is optimized the structure of gross weight, and the gross weight between the guiding rib is made into Sloping Hearth, thereby it is protruding to the ear shape to help metal flow; And the metal that can hold redundance; Therefore, need not carry out blocking and remove gross weight, only need finish-forging just can realize good molding effect checking-valve body.Because the gross weight thickness after optimizing increases and continuously, the rigidity of guiding rib is improved, therefore, in the side cut process, can effectively prevent the guiding rib distortion, do not need again it to be carried out shaping and handle.
Compare with existing technology, the utility model passes through to optimize the gross weight structure of checking-valve body, thereby effectively reduces technological process.The utility model only needs a base fetal membrane, a cover forging die, has saved die cost greatly.In process of production, only need two fire to forge, need not carry out blocking, remove gross weight and trimming, simplified production technology, shortened the manufacture cycle.Simultaneously, the utility model can alleviate the weight of blanking, has effectively improved raw-material utilization ratio, greatly reduces cost of production.
