Description

Retainer moulding combination die

Technical field

The utility model relates to the processing mold of roller bearing component retainer, particularly retainer moulding combination die.

Background technology

Two of retainer shelves limits generally all will be through 45 ° of crimpings in the prior art, 90 ° of crimpings and cut end three process and finish, each procedure all designs special-purpose mould, on a punch press, finish by workman's operation, therefore long, time-consuming, the effort of the processing and forming operation of retainer, cost height.

Summary of the invention

The purpose of this utility model provides and a kind ofly saves time, laborsaving, cost is low, can once finish the retainer moulding combination die of three process on a punch press.

The utility model is that to address the above problem the technical scheme that adopts be a kind of retainer moulding combination die, comprise punch press cope match-plate pattern and punch press lower bolster, its innovative point is: fixedly be fitted with 45 ° of crimping upper die plates and 90 ° of crimping upper die plates on the punch press cope match-plate pattern; Fixedly be fitted with 45 ° of crimping counterdies on the punch press lower bolster and cut beneath mould; 45 ° of crimping patrixes are packed on 45 ° of crimping upper die plates; Be fixed with 90 ° of crimping patrixes and cut end punch on 90 ° of crimping upper die plates, and cut in the endoporus that end punch case is contained in 90 ° of crimping patrixes; The place, plane that 90 ° of crimping upper die plates and punch press cope match-plate pattern offset has shrinkage pool, be slidingly matched in the shrinkage pool and be fitted with unloading block, the lower outer diameter place of cutting end punch is fitted with discharge ring, and the both ends of the surface of passing the ejector beam of 90 ° of crimping upper die plates offset with the bottom surface of unloading block and the upper surface of discharge ring (3) respectively.

Mould is packed on the punch press lower bolster by centring ring friction tight with it under described the cutting.

Described otch end of cutting the beneath mould of base pressure has concave station.

The degree of depth of described concave station is 0.2～0.4mm.

The utility model is owing to be fixed with 45 ° of crimping upper die plates and 90 ° of crimping upper die plates on the punch press cope match-plate pattern; Be fixed with 45 ° of crimping counterdie backing plates on the punch press lower bolster and cut the beneath mould of base pressure, simultaneously, on 90 ° of crimping upper die plates, be fitted with 90 ° of crimping patrixes that concentric locking collar is fitted together and cut end punch, like this, the every action of punch press once can be finished 45 ° of crimpings of unit one simultaneously, 90 ° of crimping moulding of second workpiece and cut the operation at the end, owing to cut the lower outer diameter place of the end punch discharge ring is housed also, after promptly each punch forming, discharge ring can be laid down workpiece.This structure is only used a sleeve forming combination die, and the action of original three process is once finished.Save time, laborsaving, reduced cost and improved work efficiency greatly.

Description of drawings

Fig. 1 is the structural representation of the utility model retainer moulding combination die;

Fig. 2 is an A portion enlarged drawing among Fig. 1.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing describes in further detail the utility model.

Referring to Fig. 1,2, a kind of retainer moulding combination die comprises punch press cope match-plate pattern 9 and punch press lower bolster 13, and its innovative point is: fixedly be fitted with 45 ° of crimping upper die plates 10 and 90 ° of crimping upper die plates 4 on the punch press cope match-plate pattern 9; Fixedly be fitted with 45 ° of crimping counterdies 12 on the punch press lower bolster 13 and cut beneath mould 7; 45 ° of crimping patrixes 11 are packed on 45 ° of crimping upper die plates 10; Be fixed with 90 ° of crimping patrixes 1 on 90 ° of crimping upper die plates 4 and cut end punch 2, and cut in the endoporus that end punch 2 is sleeved on 90 ° of crimping patrixes 1; 90 ° of crimping upper die plates 4 have shrinkage pool 4-1 with the place, plane that punch press cope match-plate pattern 9 offsets, be slidingly matched in the shrinkage pool 4-1 and be fitted with unloading block 5, the lower outer diameter place of cutting end punch 2 is fitted with discharge ring 3, and the both ends of the surface of passing the ejector beam 6 of 90 ° of crimping upper die plates 4 offset with the bottom surface of unloading block 5 and the upper surface of discharge ring (3) respectively.Adopt said structure, with 45 ° of crimpings, 90 ° of crimpings and cut the three process at the end and utilize a cover assembling die, the punch press action once just can be finished three process on two workpiece, save time, laborsaving, has reduced cost widely.

For the ease of the installation location of mould, mould 7 is packed on the punch press lower bolster 13 by centring ring 8 friction tight with it under described the cutting.

Easy to process for the retainer next process, reduce wear, we wish that the inner circle of retainer bottom surface can have a little projection, the otch end face 7-1 place of mould 7 has concave station 7-2 under described the cutting.The degree of depth of described concave station 7-2 is 0.2～0.4mm.The power that end punch produces is cut in utilization when cutting the end, cut basic skill or training's preface when finishing, and the inner circle of retainer bottom surface will form our needed projection.

Retainer moulding combination die of the present utility model in use, at first moulding combination die peace is required to adjust correspondence position, unit one is placed on 45 ° of crimping counterdies 12, under second workpiece that has had 45 ° of crimpings is placed on and cuts on the mould 7, just can open punch press, after the punching press, unit one is intact crimping operation at 45 under the effect of 45 ° of crimping patrixes 11, second workpiece then finished 90 ° of crimping moulding under the effect of 90 ° of crimping patrixes 1, simultaneously under the effect of cutting end punch 2, finish and cut basic skill or training's preface, because the end face incision of mould 7 has concave station 7-1 under cutting, then the effect of end punch 2 is cut in the bottom surface of second workpiece, can produce little ramp projections when cutting off, after cutting is finished, when punch die arrived top dead-centre, discharge ring 3 was laid down second workpiece under the effect of push rod 6 and unloading block 5, and all action is finished, the utility model is only used a sleeve forming combination die, and the punch press action once just can be finished the work of former three process simultaneously.Save time, laborsaving, reduced cost widely, be specially adapted to produce in batches.
