Abstract
The utility model relates to an evaporating diesel water tank of a single-cylinder horizontal type stamped by metal plates such as aluminum-zinc alloy steel plates, stainless steel plates and aluminum alloy plate, etc. When the edge of the water tank is matched, flanged, scrolled and riveted, an angle fillet is hard to be flanged and easy to be wrinkled; thus, the riveting is not compact and beautiful. A breach is arranged on the edge spread by a fillet plane and a superfluous metal material is trimmed by a whole-loop trimming die in one time before riveting. The deformed metal material is twisted and pressed when the breach holds riveting of an upper edge and a lower edge to realize precise and proper riveting and the whole water tank of five layers is pressed and riveted smoothly. A whole-loop wave edge reduces the starting resistance of the riveting and guides the whole edge to be gradually scrolled. The breaches of the edge of an upper and a lower body are mutually dislocated so that the breaches are held. The evaporating diesel water tank increases the manufacture cost of the die while decreases process cost, prolongs the service life of the die and realizes compact and proper riveting layer as well as neat and pleasant shape of the edges.
Description
Affiliated technical field
The invention relates to lower body on single-cylinder horizontal evaporation type diesel engine water tank, the especially water tank of a kind of sheet metal punching press riveted joint stretch steel plate water tank that back whole circle flange is riveted into one and the single-cylinder horizontal evaporation type diesel engine that this water tank is housed.
Background technique
At present, lower body the be riveted into one technological scheme of water tank of back whole whole circle flange that stretches respectively has the water tank of alleviating weight and improves the cost-effective beneficial effect of radiating efficiency on the disclosed single-cylinder horizontal evaporation type diesel engine water tank of ZL01111196.8 patent of invention.When the involutory flange of lower body bead is riveted on water tank, because lower body bead edge line is evenly to be provided with along the tank shell exterior line on traditional riveting process, the involutory flange riveting process of the straight flange of last lower body bead is better, and it is wrinkle resistant that straight flange riveted joint laminates three layers, four layers or five layers; But water tank corner fillet place on lower body bead limit involutory flange riveted joint difficulty, when steel plate thickness during greater than 0.8 millimeter, it is just wrinkling to laminate three-ply riveting, it is wrinkling serious to laminate four layers of riveted joint, the flange turnup of five layers of riveted joint is had any problem, and is wrinkling more serious, is difficult to riveted joint smoothly and produces qualified water tank.
Summary of the invention
For overcome prior art water tank corner fillet place on the difficulty of lower body bead limit involutory flange riveted joint, the invention provides a kind of technological scheme, it is wrinkle resistant to realize that whole circle flange laminates on three layers, four layers or the five layers of riveted joint water tank lower body bead limit, and can alleviate sheet metal deformation resistance when riveting, reduce the wear-out failure of steel plate to mould.
The invention solves the technological scheme that its technical problem adopts: the corner rounded edges place that launches the plane at the whole circle of water tank flange riveted joint bead is provided with gap.Before the riveting step, shaving die lower body bead edge on the water tank of stretch forming with special making punches out gap, remove the metallic material of many Yus in advance, when making the riveted joint finishing stage, each layer sheet metal of process extrusion-deformation can keep more smooth proper state.According to technical requirementss such as the width of lower body riveted joint bead on water tank corner fillet radius size, plate thickness, the water tank, the riveted joint cross section numbers of plies, one place's corner fillet is when being connected with two ends straight flange and/or curved side, and corner fillet bead edge can be provided with a plurality of gap more than and/or.The whole circle riveted joint bead cross section number of plies can be provided with three layers, four layers and/or five layers of same number of plies of whole circle, also can put in order the circle riveted joint bead cross section number of plies and be three layers, four layers and/or five layers of different number of plies and be provided with, can also be provided with more than five layers and laminate riveted joint in the different parts combination.The setting of can also staggering mutually of the gap at edge, upper body, water tank corner fillet bead place and the gap at lower body edge is covered separately gap and contains by another sheet metal when riveted joint is finished.The bead straight flange also can be done the waveform setting, make that the sheet metal of gap outer most edge is touched the earliest by flanging die on bead edge, corner fillet place and/or the straight flange bead edge in riveted joint, and can take the lead in along the mold cavity turnup, thereby guide whole bead sheet metal turnup, the synchronous turnup of resistance ratios straight line straight flange is little, and is useful to reducing mould loss prolongation die life.
The beneficial effect of the invention is: sheet metal is the water tank of steel plate punching press making single-cylinder horizontal evaporation type diesel engine particularly, lower body stretch forming respectively on the water tank, before the involutory riveted joint of last lower body, laminate riveted joint three layers, four layers or five layers of different number of plies according to the thickness of turnup sheet metal, the radius and the flange turnup of water tank corner fillet, in advance at bead edge, water tank upper body and/or water tank lower body bead edge excision remove the sheet metal of gap part, effectively eliminated and riveted wrinkling principal element.Remove the gap sheet metal and do not need to increase separately one procedure, be behind stretching process, to design and produce respectively to the water tank upper body, when the water tank lower body is made the mould of whole circle bead side cut, overcome prior art and can only make the prejudice of whole circle and the even width trajectory side cut of tank outer wall to lower body bead edge on the water tank after stretching, the whole gap that bead edge, corner fillet place should be provided with and the waveform bead at straight flange edge directly design and produce to be done on the mould that whole circle bead cuts edge, form corrugated whole ring mould otch, in the work of original side cut operation, punch out whole gap simultaneously.So, only the mould complexity improves needs to increase the Mold Making expense, in producing flow process in enormous quantities, do not increase personnel, equipment, costs such as operation, and owing to use whole circle integrally punching mould, the gap precision is guaranteed, in following road mould riveting step, the high conformity of flange turnup, the gap space that pre-sets can hold the sheet metal of extrusion-deformation in the flange turnup riveted joint process, the situation of the varied in thickness that sheet metal is extruded increase when gap not being set obviously improved, cause the wrinkling situation in bead edge to improve, riveted joint is finished and can be accessed the accurate proper percolating water that is difficult for of inner turnup extruding, the smooth water tank attractive in appearance riveted joint of outer surface bead.Gap can also hold the metallic material that periphery deforms because of extruding, and the lower body metallic material twines the effect of pushing fusion alternately generations in, makes more closely easy to leak not of riveting portion.The bead straight flange is done the waveform setting, the sheet metal of the gap outer most edge on corner fillet place and/or the straight flange bead edge can be touched the earliest by flanging die in riveted joint, and can be along the mold cavity turnup, thereby guide whole bead sheet metal turnup, make that riveted joint resistance ratios straight line straight flange turnup is little, can reduce the mould loss, prolong die life.Application sets in advance the technology of gap, and the flange turnup riveted joint that laminates more than five layers is had same beneficial effect.
