The steel ring spoke screw hole spherical mould guarantees that the position precision of the screw hole spherical surface is between phi 0.05 and phi 0.15 mm, so that the current technical requirements are completely met; meanwhile, the molding surface precision of the screw hole spherical surface is improved; and the steel ring spoke screw hole spherical mould has the advantages of simple structure, easy processing and convenient operation.
Description
Technical field
The utility model belongs to a kind of mould, specifically, relates to a kind of screw sphere mould of Automobile steel ring spoke.
Background technology
The position degree of Automobile steel ring spoke screw sphere is one of important technology index of steel ring, and it is related to the installation quality of fit of steel ring and wheel hub, and further has influence on automobile security in the process of moving.At present, in the steel ring industry, the control of the position degree index of steel ring spoke screw sphere, normally by spoke behind screw, guarantee with drill bit ream sphere hole again, because this operation whole system comprises that the positioning sleeve of drill press spindle, cutter, the locating surface of frock all can produce error, these deviation accumulations get up to make positional precision can only reach about Φ 0.5mm, and this precision has not satisfied the specification requirement that current positional precision is Φ 0.25mm.
The utility model content
Technical problem to be solved in the utility model provides a kind of machining accuracy height, steel ring spoke screw sphere mould simple in structure.
The technical solution of the utility model is: a kind of steel ring spoke screw sphere mould, and two lower bolsters that are parallel to each other are connected by guide pillar with cope match-plate pattern; At described lower bolster upper surface lower bolster is installed, on this lower bolster bottom plate is installed, circumferentially be fixed with bulb following screw bulb up in described bottom plate, the described bulb of screw bulb down exposes described bottom plate; At described cope match-plate pattern lower surface upper padding plate is installed, this upper padding plate is provided with upper mounted plate, in described upper mounted plate, circumferentially be fixed with described bottom plate in down screw bulb number equates, shape is identical, and bulb last screw bulb down, bulb of screw bulb exposes described upper mounted plate on this; The last screw bulb that is positioned at described upper mounted plate is corresponding with the last screw bulb that is positioned at bottom plate.
At first lower bolster and cope match-plate pattern are fixed on the hydraulic press, under free state, bottom plate separates up and down with last screw bulb together with the following screw bulb on it with upper mounted plate, then workpiece to be processed is placed on the bottom plate, and the aperture on the workpiece to be processed is enclosed within on the bulb of the screw bulb that is exposed to bottom plate and locatees, under the effect of hydraulic press, close up lower bolster and cope match-plate pattern then, make the last screw bulb and the following screw bulb of mutual correspondence compress spoke screw sphere, after hydraulic press pressure reaches setting, unclamp cope match-plate pattern and lower bolster, take out workpiece, promptly finish process.
Described guide pillar is a multidiameter, and bigger diameter end is fixed in the pilot hole on the described lower bolster, and miner diameter end matches with pilot hole on the described cope match-plate pattern.This structure has increased the bonding strength of guide pillar and lower bolster, makes guide pillar more stable in the course of the work, is difficult for departing from the hole on the cope match-plate pattern that cooperates with it, and makes that the processing of pilot hole is convenient.
Be set with the step guide pin bushing on the top of described guide pillar, the smaller diameter end of this guide pin bushing stretches in the pilot hole of described cope match-plate pattern.The installation of guide pin bushing makes that in the course of the work guide pillar is linked in all the time with guide pin bushing, has realized positioning action and the orientation of guide pillar to bolster well.
Beneficial effect: the utility model is power with the hydraulic press, the mode of the bulb extruding by screw bulb on the upper and lower template forms the screw sphere, the positional precision of screw sphere can be guaranteed between Φ 0.05mm～Φ 0.15mm, reached current specification requirement fully, simultaneously, also improved the profile precision of screw sphere itself; And simple in structure, processing is operated also very convenient easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A cutaway view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, a kind of steel ring spoke screw sphere mould, comprise two lower bolsters that are parallel to each other 1 and cope match-plate pattern 2, connect circular lower bolster 8 in lower bolster 1 upper surface centre by alignment pin, on lower bolster 8, connect ring-type bottom plate 4 by alignment pin, fix six bulbs following screw bulb 3a up in bottom plate 4, the bulb of these six following screw bulb 3a exposes described bottom plate 4 and circumferentially evenly distributes in bottom plate 4.Connect circular upper padding plate 9 in cope match-plate pattern 2 lower surface centres by alignment pin, on upper padding plate 9, connect ring-type upper mounted plate 5 by alignment pin, six bulbs that screw bulb 3a shape is identical down in fixing and the bottom plate 4 in upper mounted plate 5 down on screw bulb 3b, the bulb of these six following screw bulb 3b exposes described upper mounted plate 5 and circumferentially even distribution upper mounted plate 5 in; And six bulbs of going up screw bulb 3b that are installed in the upper mounted plate 5 are corresponding respectively with six bulbs of going up screw bulb 3a in being installed on bottom plate 4.Described lower bolster 1 is connected by guide pillar 6 with cope match-plate pattern 2, at two symmetrical mutually pilot holes of the both sides of lower bolster 1 processing, at two symmetrical mutually pilot holes of the also corresponding processing in the both sides of cope match-plate pattern 2, described guide pillar 6 is a multidiameter, its bigger diameter end is fixed in the pilot hole on the lower bolster 1 by interference fit, miner diameter end matches with pilot hole on the described cope match-plate pattern 2, and at the top of described guide pillar 6 suit step guide pin bushing 7, the smaller diameter end of this guide pin bushing 7 stretches in the pilot hole of cope match-plate pattern 2.
At first lower bolster 1 and cope match-plate pattern 2 are installed on the hydraulic press, under free state, bottom plate 4 separates up and down with last screw bulb 3b together with the following screw bulb 3a that fixes above them with upper mounted plate 5, then spoke 10 to be processed is placed on the bottom plate 4, described spoke to be processed 10 makes screw sphere basic forming by pre-spot-facing earlier, and guarantee certain extruding allowance, again the aperture on the spoke 10 to be processed is enclosed within on the bulb of the screw bulb 3a that is exposed to bottom plate 4 and locatees, under the effect of hydraulic press, close up lower bolster 1 and cope match-plate pattern 2 then, make six screw bulb 3a on the lower bolster 1 and six screw bulb 3b corresponding matching on the cope match-plate pattern 2, compress the screw sphere of spoke 10 to be processed, when hydraulic press pressure reaches certain pressure, screw sphere on the six pairs of screw bulbs and the spoke to be processed 10 fits like a glove, the moulding immediately of screw sphere, this processing method can make screw sphere position degree reach between Φ 0.05mm～Φ 0.15mm, reach current specification requirement, unclamp lower bolster 1 and cope match-plate pattern 2 then, take out the workpiece to be machined spoke, just finished the process of steel ring spoke screw sphere.
