Description

The contour machining procedure of stainless steel trough
Technical field
The present invention relates to a kind of contour machining procedure of stainless steel trough.
Background technology
Washing implement as kitchen and life---stainless steel trough has premium properties attractive in appearance, durable, that can not stain, has obtained increasing consumer's favor.And the table top step degree of depth of stainless steel trough generally all is below the 20mm, spatters table top easily with water, can not satisfy the demand in market.Existing traditional stainless steel trough contour machining procedure is a lot, for example the Chinese patent communique on February 7th, 2007 disclosed its publication number be " contour machining procedure of stainless steel trough " of " CN1907593 ", it at first carries out the panel die mould, formation is with the discoid body at step-like edge, carry out edge-cutting and hole-punching again, the edge is cut smooth, the bottom punching, carry out the panel hole flanging then, forming bottom through-hole inwall angle is the stainless steel faceplate of α; Carry out cell body processing: carry out the cell body blanking by supporting with it panel, adopt press device to carry out once drawing afterwards, form the groove of joining of band edge, and then carry out secondary cell body pull and stretch, forming cell body outer wall angle is the groove of joining of β, carry out edge-cutting and hole-punching again, make it form band edge, the stainless steel trough body of water falling hole is arranged at the bottom, at last, place sealing joint strip in the stainless steel faceplate bottom stage, stainless steel trough body is put into, make it the two and be fixed the stainless steel trough that formation has double flute.But this way processing technology is also complicated.So, people often want to plant and increase the degree of depth of step by taking to take turns the welder, and the wheel weldering is with panel with after joining the machine-shaping of groove difference, connect and make along joining groove and panel track edge joint weld then, weld seam is along groove edge shape ringwise like this, this kind apparatus and process complexity, moreover panel and join slot welding must weld grinding is smooth after connecing, bonding strength through the hypotenuse polishing welding seams reduces, and it is attractive in appearance to have had a strong impact on tank.
Summary of the invention
The objective of the invention is to overcome the defective and the deficiency of above-mentioned prior art,, make simple stainless steel trough for society provides a kind of simple in structure, easy to use.
For achieving the above object, the technical solution used in the present invention is: the contour machining procedure of this stainless steel trough, selected stainless steel materials, two stainless steel materials are adopted press device by the design model specification, carry out cell body processing, form the discoid body of band edge, cut edge again and the bottom punching, make it form two stainless steel billet grooves that the bottom has water falling hole, then these two stainless steel billet grooves are carried out secondary deep-drawing, form band edge, the reinforcement of the oriented upper process in edge, the R angle of chamfering is the groove of joining of 20mm-25mm around the cell body, again with the groove of joining behind the secondary deep-drawing, adopt corresponding mould, carry out punch forming, then edge band reinforcement is partly cut away, forming its centre punch of cell body has the stainless steel trough body of cell body 1 of water falling hole A and the stainless steel trough body that its centre punch has the cell body 2 of water falling hole A, two centre punch is had the cell body 1 of water falling hole A and the stainless steel trough body of cell body 2 to be welded into stainless steel trough body along two sideline A lines again; After finishing, welding carries out the processing of stainless steel faceplate: select corresponding casted die mould for use, adopt press device to carry out panel forming, form the edge and be step-like discoid body, can be the disjunctor discoid body also, the reinforcement of oriented upper process on the edge, its shoulder height α is 25mm-35mm.
At last, with the panel flange of cutting edge: with the panel behind the above-mentioned die mould just base cut edge again and the panel flange, panel after adopting pressing equipment die mould then just base compresses the formation stainless steel trough that links to each other with stainless steel trough body, panel edges is along being step-like discoid body, and the step degree of depth is that α is 25mm-35mm.
Chamfering R between the described stainless steel trough body inwall is 20mm-25mm.
Described stainless steel trough body can be two, also can be more than two.
Described cell body carries out annealing in process behind blanking, once drawing, its annealing temperature is between 1010 ℃~1060 ℃.
Stainless steel trough with contour machining procedure manufacturing of the present invention can make the step degree of depth on the table top reach 25mm-35mm, improved tank because of the shallow defective that dabbles easily, having avoided wheel to weld must be smooth with weld grinding, reduced bonding strength, it is attractive in appearance to improve tank, and has fundamentally improved the shortcoming of super dark step tank manufacturing process difficulty, saved cost greatly, shortened product development cycle, saved the expense of material, can reduce labor intensity simultaneously.
