Abstract
The utility model discloses an octagonal blank used for producing an automotive muffler partition plate, which comprises a partition plate blank. The partition plate blank is an octagonal blank plate; the two waist edges of the octagonal blank plate are respectively intersected with the horizontal central axis of the blank plate; the two bottom edges of the octagonal blank plate are respectively intersected with the perpendicular central axis of the blank plate; the flanging width of the two waist edges and the two bottom edges of the octagonal blank plate is less than the flanging width of four beveled edges of the octagonal blank plate. By improving the original elliptic (or round or triangular or trapezoidal or square and the like) partition plate blank into the octagonal blank plate, for the part in which the flanging width of the partition plate blank is not required highly, the flanging width is reduced from 10-12 mm to 5-6 mm, thereby reducing the material consumption, being more economic and more environmentally-friendly. The octagonal blank used for producing the automotive muffler partition plate is suitable for mufflers.
Description
Technical field
The utility model relates to silencing apparatus, particularly a kind of Octagon blank that is used to produce the automotive muffler dividing plate.
Background technique
At present, automotive muffler is the device that is exclusively used in the automotive silencing vent systems, is used to eliminate the burning and gas-exhausting noise of motor.Silencing apparatus is made up of suppressor case, end cap, hush tube and dividing plate, and described dividing plate adopts the Stainless Sheet Steel stamped usually, and the stamping process flow process is as follows: sheet material → be cut into billot → dividing plate punching and blanking → shaping hole flanging.
Because dividing plate be ellipse (or circle or triangle trapezoidal or square etc.), so traditional dividing plate blank also correspondence is designed to ellipse (or circle or triangle trapezoidal or square etc.), after the drawing, dividing plate flange height complete cycle is contour, and (for satisfying intensity, the height of dividing plate flange generally is designed to 10～12mm).But, be that (in the not high position of requirement of strength, the height of dividing plate flange generally is designed to 5～6mm) to 10～12mm so be not that the flange height of each section dividing plate all requires because the flange of dividing plate is not the requirement that each section all has intensity.Like this, though traditional blanking dividing plate can satisfy the usage requirement of dividing plate, exist the consumption of materials height, uneconomic shortcoming.
Summary of the invention
The purpose of this utility model is to provide the Octagon blank that is used to produce the automotive muffler dividing plate that a kind of technology is simple and consumption of materials is little at above-mentioned deficiency, to realize reducing the purpose of manufacture cost.
In order to realize above purpose, a kind of Octagon blank that is used to produce the automotive muffler dividing plate that the utility model provides, comprise the dividing plate blank, described dividing plate blank is the Octagon blank flat, two waist limits of this Octagon blank flat are crossing with the horizontal center line axis of blank flat respectively, and two bases of described Octagon blank flat are crossing with the vertical centre axis of blank flat respectively; The two waist limits of described Octagon blank flat and the flange width on two bases are less than the flange width of four hypotenuses of described Octagon blank flat.
Two waist limits of described Octagon blank flat are vertical with the horizontal center line axis of blank flat respectively, and two bases of the described Octagon blank flat vertical centre axis with blank flat respectively are vertical.
The two waist limits of described Octagon blank flat and the flange width on two bases are 5～6mm, and the flange width of four hypotenuses of described Octagon blank flat is 8～12mm.
The utility model is by being improved to the Octagon blank flat with former ellipse (or circle or triangle trapezoidal or square etc.) dividing plate blank, the part not high to the flange width requirement of dividing plate blank, the flange width is reduced to 5～6mm from 10～12mm, thereby reduced consumption of materials, more economical, more environmental protection.Certainly, the utility model can also be applicable to the dividing plate of shapes such as circle or triangle be trapezoidal or square.
The utlity model has that technology is simple, consumption of materials is little and characteristics such as more economical environmental protection.
Description of drawings
Fig. 1 is the structural representation of present embodiment.
Fig. 2 is the structural representation of conventional baffle blank.
Fig. 3 is the side view of the dividing plate blank behind the flange behind the present embodiment flange.
Among the figure: the dividing plate blank behind 1-dividing plate blank, 11-waist limit, 12-base, 13-hypotenuse, 2-flange, the 3-flange.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment: as shown in Figure 1, a kind of Octagon blank that is used to produce the automotive muffler dividing plate, comprise dividing plate blank 1, described dividing plate blank 1 is the Octagon blank flat, two waist limits 11 of this Octagon blank flat are vertical with the horizontal center line axis of blank flat respectively, and two bases 12 of the described Octagon blank flat vertical centre axis with blank flat respectively are vertical; The two waist limits 11 of described Octagon blank flat and the flange width on two bases 12 are less than the flange width (referring to Fig. 2) of four hypotenuses 13 of described Octagon blank flat.
The two waist limits 11 of described Octagon blank flat and the flange width on two bases 12 are 5～6mm, and the flange width of four hypotenuses 13 of described Octagon blank flat is 8～12mm.
As shown in Figure 3, behind this Octagon dividing plate blank flange, flange 2 complete cycles of the dividing plate blank 3 behind flange height is uneven, minimum flange 2 highly has only 5mm, like this, make the consumption of materials of making dividing plate reduce by 10%～15%, thereby reach the purpose that reduces the vent systems deadweight and reduce manufacturing expense.
As development of the present utility model, can also adjust the limit number of described dividing plate blank 1 according to actual needs; And the utility model also can make suitable modification, is applicable to the dividing plate of shapes such as circle or triangle be trapezoidal or square.
