The utility model is characterized in that a cavity die (5) is fixed on the lower template (9) and is connected with a seat insert (6), the seat insert (6) is fixed on the lower template (9) and is in a movable correspondence with a forging positioning plate (7); a backing plate (8) is arranged under the positioning plate (7), and a forging eject-rod (10) passes through the lower template (9) and is touched with the backing plate (8) with the end face. The utility model avoids defects of the existing art like side collapse and corner collapse on the surface while trimming and dressing a fork forging, thus ensuring the quality of the forging.
Description
Technical field
The utility model relates to a kind of shaving die, can guarantee the do not collapse edger of fork forgings at limit, the angle of collapsing of forging outer surface during particularly a kind of the side cut.
Background technology
In the industrial production, the metal forging need be repaired processing with stamping machine to outer surface.At present, fork forgings is after particularly the fork forgings made of punching press is made, and the often out-of-flatness of the arc edge of its outer surface often has overlap and burr, generally all will be through the finishing of cutting edge.When cutting edge finishing, with the downward punching press of patrix, forging transfixion, this method is because edger during to the punching press of metal forging, and the outer surface of metal forging is easy to generate the collapse angle and the limit of collapsing, and causes product quality undesirable.
Summary of the invention
The utility model purpose is, a kind of edger of fork forgings is provided, and it can overcome the shortcoming of prior art, and when fork forgings being cut edge finishing, its outer surface can not produce the limit of collapsing, the angle of collapsing, and can guarantee the quality of product.
The purpose of this utility model is achieved like this:
The cope match-plate pattern below is connected with the punch location-plate, is connected with upper padding plate between cope match-plate pattern and the punch, punch location-plate and punch interference fits; Cope match-plate pattern is connected with lower bolster by lead and guide pin bushing, and die is fixed on the lower bolster, and die is connected with seat ring, and seat ring and forging location-plate are slidingly matched, and seat ring is fixed on the lower bolster; The below of location-plate is provided with lower bolster, and the forging ejector beam passes lower bolster, and its end face contacts with backing plate.
Owing to adopted such scheme, on lower bolster, increased the device that workpiece is moved, the workpiece of the fork forgings of needs finishings is placed on the forging location-plate, with the up and down acting surface location of seat ring to the fork forgings workpiece, when mould is cut edge, punch is cut edge to the face in the fork of fork forgings, generation is collapsed angle and the limit of collapsing all at inner surface, because the inner surface of fork forgings also will be processed, can not have influence on the outer surface requirement of product, also the unnecessary part of fork forgings is repaired simultaneously, therefore can guarantee the quality of product, also have the high advantage of product percent of pass.
Through using in forge, the fork forgings product with the processing of this edger reaches designing requirement to the utility model in Chang'an company, can satisfy and produce needs.
Description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 be among Fig. 1 along A-A to vertical view.
Among the figure, 1 is cope match-plate pattern; 2 is upper padding plate; 3 is punch; 4 is the punch location-plate; 5 is die; 6 is seat ring; 7 is the forging location-plate; 8 is lower bolster; 9 is lower bolster; 10 is ejector beam; 11 is fork forgings; 12 is alignment pin; 13 is screw; 14 is lead; 15 is guide pin bushing; 16 is locating surface; 17 is locating piece.
The specific embodiment
Circular arc limit with the processing fork forgings is that example is described further the utility model.
Referring to Fig. 1 and Fig. 2, below cope match-plate pattern 1, be connected with punch location-plate 4 with screw 13, be connected with upper padding plate 2 between cope match-plate pattern 1 and the punch 3, punch location-plate 4 and punch 3 interference fits, cope match-plate pattern 1 is connected with lower bolster 9 by lead 14 and guide pin bushing 15.
Die 5 is fixed on the lower bolster 9 by screw and pin 12, and die 5 is connected with seat ring 6, and seat ring 6 is fixed on the lower bolster 9, and the last plane of die 5 and the last plane of seat ring 6 are on same plane.Seat ring 6 tops are provided with two locating pieces 17, and locating piece one end is corresponding with the side of fork forgings, are used for 16 location of face about fork forgings.Die 5 upper surfaces are the arc surfaces less than semicircle, and its center is provided with groove, and groove is corresponding with the top of workpiece.
The end of seat ring 6 is provided with opening, to guarantee that oxide skin and iron filings can blow away with compressed air when the punching press, avoids being deposited in forging and die edge, the quality that influence is cut edge, and the middle part is provided with left and right sides locating surface 16, is used for the location, side to fork forgings.
The rear end of forging location-plate 7 is provided with the forging resigning hole, is used for easily placement and taking-up with fork forgings.Front end at forging location-plate 7 is provided with confined planes, is used for fixing the front and back position of fork forgings.Seat ring 6 is slidingly matched with forging location-plate 7, guarantees can slide between forging location-plate 7 and the seat ring 6, and when sliding up and down, does not produce dislocation and rotation.The below of forging location-plate 7 is provided with lower bolster 8, forging ejector beam 10 passes lower bolster 9, its end face contacts with backing plate 8, ejector beam 10 can be moved in lower bolster, and guarantee that forging location-plate 7 is subjected to power upwards all the time, the size of its power determines that according to the workpiece size of fork forgings principle is to keep forging location-plate 7 when not cutting edge, and can not freely move; When cutting edge, can not have influence on the operate as normal of side cut.
During this mold work, the fork forgings 11 of needs finishing is placed on forging location-plate 7 tops, the top of fork forgings 11 is dropped in the groove at die center, and the front-back of fork forgings 11 leans against on the confined planes of forging location-plate, and fork forgings is located up and down; On the left and right sides confined planes that leans against seat ring 6 of fork forgings 11, fork forgings is fixed.Start stamping machine, ejector beam 10 drives lower bolster 8 and moves upward, and lower bolster 8 drives forging location-plate 7 again and moves upward, and the fork forgings 11 that is fixed on the forging location-plate 7 also moves upward with location-plate 7; Simultaneously, cope match-plate pattern 1 drives upper padding plate 2 and moves downward, and upper padding plate 2 drives punch 3 again and moves downward.After punch 3 touched fork forgings, fork forgings was subjected to a downward power, and this moment, forging fork inner arc surface contacted with die 5, and the arc surface in the forging fork is cut edge.
After side cut was finished, cope match-plate pattern 1 drives upper padding plate 2 and punch 3 moves upward, and gets back to initial position.Ejector beam 10 drives lower bolster 8, forging location-plate 7 and fork forgings and moves downward, and also gets back to initial position, takes out forging, finishes an impulse stroke.Change the placement direction of forging again, the another side circular arc is cut edge, so just machine a fork forgings, the forging of gained meets technological requirement.
The shape setting of the workpiece that the shape of the left and right sides locating surface of seat ring, the front and back locating surface of forging location-plate and die can be repaired as required.
