The specific embodiment
Below by specific instantiation embodiment of the present utility model is described, those skilled in the art can understand other advantages of the present utility model and effect easily by the disclosed content of this specification.The utility model can also be implemented or be used by the other different specific embodiment, and the every details in this specification also can be based on different viewpoints and application, carries out various modifications or change under the spirit of the present utility model not deviating from.
See also Fig. 3 to Fig. 7.Notice, the appended graphic structure that illustrates of this specification, ratio, size etc., equal contents in order to cooperate specification to disclose only, understand and reading for person skilled in the art scholar, be not to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this specification as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.
Such as Fig. 4 and shown in Figure 5, the utility model provides a kind of processing unit (plant) of curved surface step lining, it comprises a progressive die, this progressive die comprises patrix 1 and counterdie 2, be divided into successively by lining material direction of feed in the progressive die rush oil groove processing district 3, edge-cutting and hole-punching district 4,5, overwhelm angular region 6, finish trimming district 7, the hasp district 8 that falls, each regional correspondence is provided with the punch that links to each other with patrix, the die that links to each other with counterdie.The utility model adopts progressive die to finish simultaneously the processing of an operation of multi-disc lining material, and finish the processing of curved surface step by the side cut operation of progressive die, saving traditional curved surface step need to process by Digit Control Machine Tool, improved production efficiency, rush the symmetry that oil groove and punching have guaranteed oil groove, punching by mould simultaneously, improved the quality of production of lining.
The patrix that correspondence is rushed oil groove processing district 3 is provided with two oil groove punch 31, guarantees that the oil groove of going out does not depart from the center, has improved the lining quality.The patrix in corresponding edge-cutting and hole-punching district 4,5 is provided with side cut punch 41, piercing punch 51, and counterdie is provided with the trim die 42 corresponding with the punch 41 of cutting edge, the punching concave die 52 corresponding with piercing punch 51; The patrix that correspondence overwhelms angular region 6 is provided with interior chamfering punch 61, and counterdie is provided with outer chamfering punch 62.The patrix in corresponding finish trimming district 7 is provided with finish trimming punch 71, counterdie is provided with the finish trimming die 72 corresponding with finish trimming punch 71, be processed to form the curved surface step by side cut and finish trimming at the lining material, save the step of traditional Digit Control Machine Tool processing curve step.The fall patrix in hasp district 8 of correspondence is provided with hasp punch 81, and counterdie is provided with hasp die 82.This progressive die can be finished the processing of the corresponding operation of a plurality of lining material, can produce in batches, has improved production efficiency.
As shown in Figure 3, the processing of above-mentioned curved surface step lining may further comprise the steps: 1) the lining material is placed finish in the above-mentioned progressive die rush oil groove, edge-cutting and hole-punching, overwhelm the angle, finish trimming and the hasp that falls; 2) rush again U-shaped, the shaping of punching circle; 3) last fine cylindrical.Add man-hour, the lining material is sent into by pay-off on the feed lead rail of progressive die, then enters successively next processing district by the material pusher, when starting progressive die, can finish the processing of a plurality of lining material of a plurality of operations, has saved process time, enhances productivity.This progressive die can be realized rushing oil groove, edge-cutting and hole-punching, overwhelms the angle, finish trimming and the hasp that falls, by the position of each operation strictly is set, and the feed speed of lining material, and each lining material can be guaranteed the crudy of lining in the location of each processing district.
Above-mentioned progressive die can also be provided with the district 9 that stamps an embosed seal, and finishes adding a cover of steel seal, and the district that stamps an embosed seal can be arranged on and overwhelm 7 in angular region 6, finish trimming district.Step 2) and step 3) can adopt processing technology of the prior art, therefore, the utility model is finished a plurality of operations in progressive die, can produce in batches, satisfies the demand of amount; Simultaneously, when rushing oil groove by rush arranging of oil groove punch guaranteed oil groove to centrad, avoid oil groove to depart from the center, improved product quality.
Be to improve the crudy of lining, the working width size of finish trimming punch corresponding to above-mentioned finish trimming district, finish trimming die is less than shaping lining width dimensions.As shown in Figure 6, lining expanded view after the shaping, because the lining material is through the overshoot U-shaped, after the punching circle is shaped, large end A and the small end B of lining material, the size meeting broadening of C, therefore when finish trimming, the width at the Width shaping lining two ends that above-mentioned progressive die processing lining material two ends form is answered little 0.5mm-1.5mm, be that finish trimming die and finish trimming punch are in corresponding A, B, the working width at C three places is than the little 0.5mm-1.5mm of width at corresponding three places of shaping lining, the width D around the punching particularly, finish trimming die and finish trimming punch are at the working width of the punching place little 1.5-2.5mm of corresponding width than punching place of shaping lining.By to the die in finish trimming district, the structure setting of punch, guaranteed the needs of lining shaping width, improve the quality of lining.
The lining sheet stock is after being shaped through overshoot U-shaped, punching circle, the distortion of inside and outside chamfering is inhomogeneous, near being that E district and oil groove place are that the chamfering in F district among Fig. 7 is understood the little of change behind fine cylindrical among Fig. 7 near the hasp, so outer chamfering punch 61, all the chamfer dimesion than product shaping backlash oil groove place, hasp place is large at the chamfer dimesion that rushes oil groove place, hasp place for interior chamfering punch 62.By overwhelming the punch setting of angular region, in order to guarantee the quality of production of lining.
In sum, the processing unit (plant) of curved surface step lining of the present utility model has improved production efficiency, has guaranteed simultaneously the quality of production.So the utility model has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not is used for restriction the utility model.Any person skilled in the art scholar all can be under spirit of the present utility model and category, and above-described embodiment is modified or changed.Therefore, have in the technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences of finishing under spirit that the utility model discloses and the technological thought, must be contained by claim of the present utility model.
