Abstract
The utility model discloses a forming die of an annular corrugated sheet of an oil and mist separator. The forming die comprise an upper die body and a lower die body, wherein the upper surface of the lower die body is provided with one or more through grooves with the transverse sections in an isosceles trapezoid shape, the angle of bottom corner of each isosceles-trapezoid-shaped through groove is 120 degrees, each isosceles-trapezoid-shaped through groove is in a cone shape with the wide outer end and the narrow inner end in the width direction, the two or more isosceles-trapezoid-shaped through grooves in the upper surface of the lower die body are radially distributed, and the lower surface of the upper die body is provided with protruding blocks matched with the isosceles-trapezoid-shaped through grooves in the lower die body. The forming die has the obvious advantages of being free of attachment welds, low in process cost and high in size and shape accuracy of the annular corrugated sheet.
Description
Technical field:
The utility model relates to a kind of stamping technology, the finishing die that a kind of especially oil mist separator is annular corrugated.
Background technology:
Ring segment by trapezoidal ripple builds up the cellular oil mist separator of regular hexagon, is widely used in engine because its separating property is outstanding.Yet, this annular corrugated in stamping process, blank by bending, stretcher strain, its cylindrical, diameter of bore all can shrink and diminish, if adopt Integratively formedly, blank is subject to the frictional resistance effect of punch and matrix, material can not proper flow, and qualified part cannot be shaped.At present, external employing is divided into a plurality of fanning strips by annular corrugated and is formed separately, then with being welded to connect, circularize corrugated plate, on this annular corrugated, there are a plurality of attachment welds, this weld seam needs can bear engine in tens thousand of effects that leave mental and physical efforts, thereby very high to the requirement of welding procedure, and the planarization of weld seam requires highly, and otherwise to regular hexagon, cellular formation exerts an influence when affecting ring change shape corrugated plate and stacking.
Summary of the invention:
The utility model object is to provide a kind of annular corrugated finishing die without attachment weld.
Realizing the utility model object and technical scheme is, the finishing die that a kind of oil mist separator is annular corrugated, comprise upper die and lower die, it is characterized in that: the upper surface of described counterdie is at least provided with the groove that a cross section is isosceles trapezoid, the angle of described isosceles trapezoid groove footing is 120 °, the width of the groove of described isosceles trapezoid groove is the wide and inner narrow taper in outer end, isosceles trapezoid groove on described counterdie upper surface is two when above, each isosceles trapezoid groove radially distributes, the lower surface of described patrix be provided with described counterdie on the projection that matches of isosceles trapezoid groove.
The utility model has without attachment weld compared with the prior art, process costs is low and annular corrugated chip size and the high remarkable advantage of form accuracy.
Accompanying drawing explanation:
Fig. 1 is the structural representation of annular corrugated of the utility model, Fig. 2 is the bellows-shaped schematic diagram of annular corrugated, Fig. 3 is the annular corrugated honeycomb figure that stack forms, Fig. 4 is the expanded view of annular corrugated, Fig. 5 is the annular corrugated plate blahk structure schematic diagram that is shaped, Fig. 6 is the mould structure schematic diagram of annular corrugated plate of being shaped, and Fig. 7 is that the A of Fig. 6 is to schematic diagram.
The specific embodiment:
The defect that the utility model exists in order to solve prior art, adopt the mode of circular material blank ripple of part formation several times in finishing die to make complete annular corrugated, maximum ripple numbers that finishing die once can be shaped need be determined through experiment, for different size and material, be different.Now in conjunction with 0Cr18Ni9 stainless steel annular corrugated plate part, accessory size specification: external diameter
for 117mm, internal diameter
for 149mm, expecting thick is 0.1mm, and waveform is isosceles trapezoid, and part has 129 ripples.The ripple (trapezoidal wave) that is shaped on annular element, the internal diameter of part and external diameter all will shrink and diminish, and cannot adopt whole part by one-step whole waveforms that are shaped.The utility model is to overcome a plurality of parts of existing employing to form by welding the weld seam problem that annular waveform part produces, the method that the utility model adopts local segmentation to form is made complete annular corrugated sheet, through great many of experiments, 3 waveforms are shaped at every turn, need to be shaped and make a part for 43 times, many groups are repeatedly shaped, need to solve the accurate location of part forming, and location structure should be reliable, the utility model adopts, in the inside of internal diameter and the outside of external diameter of part, locating hole to be set respectively, respectively with lower bolster on alignment pin slippery.
According to the size of part, calculate and launch to be of a size of, D
' and D
' ' .During due to shaping, the internal-and external diameter of part blank all will shrink and diminish, and its amount of contraction is not that theory can accurately draw, needs draw through experiment.Consideration arranges inside and outside two technology holes on blank, needs strengthen the outside dimension of above-mentioned blank and reduce internal diameter size, draws blank dimension of inner and outer diameters, as shown in Figure 5.Locating hole is arranged on three middles in waveform.
Mould structure of the present utility model is that patrix is formpiston 2, counterdie is cloudy (recessed) mould 4, sliding joining of guide pillar 3 on pilot hole on cope match-plate pattern 1 and lower bolster 7, counterdie is provided with that to be actiniform three isosceles trapezoid grooves 5 relative with three isosceles trapezoid projections 8 on patrix, on above-mentioned lower bolster, be provided with two alignment pins 6, the isosceles trapezoid groove on described counterdie is the narrow taper groove in wide the inner, outer end.
Each ripple quantity being shaped must make the part quality that is shaped meet the requirements, and the ripple number of once-forming is many, and production efficiency is high, and the ripple number of shaping is few, and efficiency is low.The waveform number that above-mentioned example provides is 129 ripples, is the integral multiple of three waveforms of once-forming, 43 times, when part waveform number is not the integral multiple of waveform number of once-forming, can adopt second mould be shaped separately remaining waveform, now Efficiency Decreasing.Another kind method is, when remaining waveform number is 2 ripples or 1 ripple, to 2 ripples, locating hole is located at the middle of these two ripples, to 1 ripple, locating hole is located at the center of this waveform.
Shaping of the present utility model and method of operating, the annular blank part with locating hole is placed on lower bolster, and in inciting somebody to action, outer two locating holes are enclosed within on two alignment pins on counterdie, under patrix, exercising blank forming goes out after three isosceles trapezoid ripples, patrix is up separated with counterdie, make by hand the trapezoidal mould of the waveform disengaging counterdie of blank, move it three pitch of waves, and after making another two locating holes be enclosed within on alignment pin, second three isosceles trapezoid ripple is shaped, until 129 waveforms are all shaped complete, take out annular corrugated, with line, cut by this part, outside dimension requires excision locating hole part, obtain qualified annular corrugated heat exchange part, with above-mentioned annular corrugated of of being shaped, be assembled into cellular oil mist separator, by soldering, be combined into one.
Adopt that made annular corrugated of above-mentioned shaping dies has advantages of no-welding-seam, intensity is good, the life-span is long.
