Stainless steel kettle and one drawing process thereof
Technical field
The present invention relates to a kind of stainless steel kettle and one drawing process thereof.
Background technology
Tradition stainless steel kettle kettle body process is for the fan-shaped material-bending that falls-straight weld-roll extrusion weld seam-round as a ball-turning over base-La expands, and so just forms a kettle body blank.But traditional handicraft route more complicated; Each station all needs workman and machine; Waste too many human and material resources cost, and the vertical masonry joint welding quality is to influence the kettle body to draw a factor that expands and to scrap most critical, welds well and can prevent sealing-off; Therefore smooth, slick and sly, tight, the no rosin joint of welding, no rust staining, no burr can guarantee that the kettle body does not ftracture along the commissure when bloated drawing like this.Secondly, cannot see in order to make weld seam, need carry out degree of depth polishing to stainless steel kettle body, just throw smart then the throwing earlier, can produce a large amount of dust like this, not only diminishing enterprise employee health also can contaminated air.At last, water transfers gaseous state to from liquid state when boiling, owing to heat up water thermal source below water; So the water of bottom is gasification earlier, the less rising of gas density is because gas receives the pressure from water in the underwater; Pressure constantly reduces in uphill process, causes the volume of gas constantly to increase, and arranges and drives liquid and roll; The common ripple kettle that do not rise and fall, the flow-disturbing of the ripple that do not rise and fall is for anti-sealing spills in kettle; Maximum stage and Hu Kou or Hu Zui are bigger apart from needs, cause kettle body space waste.
Summary of the invention
To the shortcoming of prior art, the purpose of this invention is to provide a kind ofly do not have welding, operation is few, cost is low, the stainless steel kettle one drawing process of anti-drawing crack;
Simultaneously, the present invention also provides a kind of stainless steel kettle.
For realizing above-mentioned purpose, technical scheme of the present invention is: a kind of stainless steel kettle one drawing process, and it may further comprise the steps:
A, the disk material falls: calculate the size stainless steel sheet stock that fallen according to the shapometer of needed kettle;
B, one stretch: the mould that is furnished with the fluctuating ripple on the punch is provided, and blanking disk material is sent in the said mould;
C, shaping: a dressing stick is provided, and the die ripple on the dressing stick just in time with mould on the interlock of punch ripple, die contacts shaping with the kettle body, makes kettle body lines and mould lines in full accord;
D, side cut: the kettle after the shaping is cut edge by kettle body bottom profile dimensional requirement on particular manufacturing craft and forcing press;
E, punching: Hu Kou and Hu Zui are carried out punching, finally obtain kettle.
Among the step a, the thickness of said stainless steel sheet stock is 0.3mm-1.0mm.
Among the step b, the difference of said fluctuating ripple crest and trough is in 30mm.
Simultaneously, the present invention also provides a kind of stainless steel kettle, comprises the kettle body, and kettle is provided with a plurality of fluctuating ripples on one's body.
Said a plurality of fluctuating ripple and kettle are as the one drawing and forming; The difference of said a plurality of fluctuating ripple crest and trough is in 30mm.
Compared with prior art, the present invention has following beneficial effect:
1) for making one stretching stainless steel kettle the technology assurance is provided; Making does not have welding between the stainless steel kettle of making through this technology, thereby it is many to have overcome the operation that causes because of welding, waste of material; Defectives such as cost of labor is many; For enterprise has reduced production cost: 2) avoided in drawing the process that expands, quality problems such as leak that drawing crack or occur leaks that weldering, sealing-off cause in the commissure make this stainless steel insulating pot in market competition, have price and quality-advantage; 3) overcome for weld seam is covered, need carry out degree of depth polishing process, avoided producing a large amount of dust, helped environmental protection stainless steel kettle body; 4) kettle body undulations has the flow-disturbing effect, and anti-sealing spills in kettle, makes the available space of kettle bigger, and is also more attractive in appearance when kettle is safer.
Description of drawings
Fig. 1-Fig. 8 is the process schematic representation of stainless steel kettle one drawing process of the present invention.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is carried out detailed description.
The present invention discloses a kind of stainless steel kettle, and it comprises the kettle body, and kettle is provided with a plurality of fluctuating ripples on one's body.Said a plurality of fluctuating ripple and kettle are as the one drawing and forming.The difference of said a plurality of fluctuating ripple crest and trough is in 30mm.
In addition, the invention discloses a kind of stainless steel kettle one drawing process, it may further comprise the steps:
(1) blanking: according to kettle figure shape and size, the selection of material thickness calculates blanking, on forcing press with blanking die punching press diameter 335mm stainless steel sheet stock (Fig. 1).
(2) one stretches: select particular manufacturing craft, 335mm stainless steel disk material behind the blanking is sent into forcing press, flow arbitrarily in order to stop material; The kettle body is produced stablize the fluctuating ripple; Reasonable Arrangement fluctuating ripple on the mould punch in advance, the distance of mould crest and trough is 10mm, carries out one then and stretches; This moment, the degree of depth of kettle body was 120mm, and kettle body lines is than mould lines shallow slightly (Fig. 2).
(3) shaping: the die ripple just in time with the interlock of punch ripple, it contacts the beginning shaping with the kettle body, make kettle body lines and mould lines in full accord, the distance of kettle body crest and trough is 10mm, after stretching than one regular more neatly (Fig. 3).
(4) cut edge: the kettle after the shaping is cut edge by kettle body bottom profile dimensional requirement on particular manufacturing craft and forcing press, and making kettle body base diameter is 200mm (Fig. 4).
(5) punching: on particular manufacturing craft and forcing press, go out kettle oral pore (Fig. 5).
(6) hole flanging: on particular manufacturing craft and forcing press, turn over kettle oral pore (Fig. 6).
(7) punching: on particular manufacturing craft and forcing press, go out pot mouth hole (Fig. 7).
(8) punching: on particular manufacturing craft and forcing press, go out handle hole (Fig. 8).
