Technical field
The utility model relates to punch process mould field, and specifically one cuts crowded compound finishing processing mold.
Background technology
In the industry such as automobile, electronics, there are some tabular local Precise outline parts, as parts such as automobile angle-adjusting tooth plates, the feature of this kind of part is that some local configuration dimensional accuracy and contoured surface quality requirement are high, and other parts are less demanding.The processing of current tabular local Precise outline part has mainly been come by Milling Process, essence punching or trimming.Milling Process belongs to machining, and its working (machining) efficiency is low, and cost is higher, is difficult to satisfied current market to the demand of this kind of part.The method of another kind of processing precise profile plate part is the punching of gear ring flanging essence, and this technique needs expensive special three dynamic fine blanking press, and its mould structure is complicated, and cost is high, makes part manufacturing cost high; For the plate part only needing local Precise outline to be shaped, with the whole profile of precision punching method formation of parts, seem and compare waste, in addition for some low module profiled parts, also cannot be shaped with precision punching method.Trimming is also a good method of this kind of part of processing, but the current study mechanism of this technique is little, and forming technology law study is also few, and instructs the theory of processed and applied and technological standards to be left to be desired.
Therefore, one is needed to carry out " smart cutting+plastic extrusion " workpiece to be machined local configuration, reach the processing of local Precise outline, to improve local tooth profile dimensional accuracy, that just can be able to process on ordinary press cuts crowded compound finishing processing mold simultaneously.
Utility model content
In view of this, the purpose of this utility model overcomes defect of the prior art, there is provided a kind of to carry out " smart cutting+plastic extrusion " workpiece to be machined local configuration, reach the processing of local Precise outline, to improve local tooth profile dimensional accuracy, that just can be able to process on ordinary press cuts crowded compound finishing processing mold simultaneously.
Of the present utility modelly cut crowded compound finishing processing mold, the die comprising cope match-plate pattern, lower bolster, the punch be fixedly connected with described cope match-plate pattern and be fixedly connected with described lower bolster; Described die be provided with for punch to coordinate with die cut after blanking cavity and for carrying out fine positioning to the profile outer rim of workpiece and carrying out the type groove of plastic extrusion;
Further, the alignment pin coordinating with inner hole of workpiece and carry out initial alignment is provided with in described type groove;
Further, described cope match-plate pattern bottom surface is fixed with upper padding plate; Described upper padding plate bottom surface is fixed with punch retainer and this punch retainer is provided with fixing hole for fixing exhaled punch;
Further, be fixed with stripper below described punch retainer and be provided with rubber between stripper and punch retainer; Described stripper bottom surface is provided with dodges hole for what dodge described alignment pin;
Further, described lower bolster end face is vertically fixed with guide pillar, described cope match-plate pattern is fixed with the guide pin bushing be slidably matched with described guide pillar;
Of the present utility modelly cut crowded compound finishing processing mold and also comprise fastening assembly, described fastening assembly comprises from top to bottom successively through the upper pin of cope match-plate pattern, upper padding plate and punch retainer and from top to bottom successively through the lower pin of die and lower bolster;
Further, described fastening assembly also comprises the screwing being fixedly connected with cope match-plate pattern and punch retainer, the lower screw being fixedly connected with lower bolster and die, the unloading bolt being fixedly connected with stripper and cope match-plate pattern and the rotation stopping screw be radially fixedly connected between described punch and cope match-plate pattern.
The beneficial effects of the utility model are: of the present utility modelly cut crowded compound finishing processing mold, complete while workpiece to be machined cuts in die and punch matched moulds process, utilize the type groove on die to carry out plastic extrusion to workpiece to be machined, reach the processing of local Precise outline.The local tooth profile dimensional accuracy of Mould Machining of the present utility model is high, contoured surface is little collapses that angle entire bright band is shaped, perpendicularity is high, have very high fineness.And this mould just can realize processing on ordinary press, without the need to expensive special three dynamic fine blanking press, reduce the requirement to equipment, mould structure is simple, and cost is low.Type groove in this female die of die is to workpiece profile outer rim fine positioning, and restriction workpiece, in the slip of process, ensures the accurate location of process, and solve the problem that the pre-made allowance of general finishing process is little, location is difficult, its workpiece is reserved finishing surplus and is only 0.2mm.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cavity die structure schematic diagram of the present utility model;
Fig. 3 is punch structure schematic diagram of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure, the present embodiment cut crowded compound finishing processing mold, the die 14 comprising cope match-plate pattern 1, lower bolster 17, the punch 7 be fixedly connected with described cope match-plate pattern 1 and be fixedly connected with described lower bolster 17; Described die 14 be provided with for punch 7 to coordinate with die 14 cut after blanking cavity 141 and for carrying out fine positioning to the profile outer rim of workpiece and carrying out the type groove 143 of plastic extrusion, complete while workpiece to be machined cuts in die 14 and punch 7 matched moulds process, utilize the type groove 143 pairs of workpieces to be machined on die 14 to carry out plastic extrusion, reach the processing of local Precise outline.The local tooth profile dimensional accuracy of Mould Machining of the present utility model is high, contoured surface is little collapses that angle entire bright band is shaped, perpendicularity is high, have very high fineness.And this mould just can realize processing on ordinary press, without the need to expensive special three dynamic fine blanking press, reduce the requirement to equipment, mould structure is simple, and cost is low.Type groove in this female die of die 14 143 pairs of workpiece profile outer rim fine positionings, restriction workpiece is in the slip of process, ensure the accurate location of process, solve the problem that the pre-made allowance of general finishing process is little, location is difficult, its workpiece is reserved finishing surplus and is only 0.2mm.
