Description
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.Since the raw material costliness of stainless steel trough, and complicated its cost of processing technology is higher, so price is high always.Moreover, all needing corresponding moulds of industrial equipment during general stainless steel trough processing and forming, fangle product of every exploitation needs a whole set of mould supporting with it, so development cost are very high and the cycle is long, can not in time satisfy the demand in market.Existing traditional stainless steel trough moulding process roughly can divide three kinds of forms:
1, wheel weldering, its adopts panel and the supporting with it groove of joining respectively after the machine-shaping, welds mutually, then weld seam is polished, the welding equipment of this method costs an arm and a leg, and the groove of joining of each model all needs corresponding welding copper mold, so equipment investment is considerable.Moreover panel and join slot welding must weld grinding is smooth after connecing, both increased workload, increased working strength of workers again, produce dust, noise during polishing, cause environmental pollution, be unfavorable for workman's physical and mental health.
2, butt welding, it adopts the groove of joining of two zone face plates to weld mutually.This is the most general production method of present stainless steel trough, though cost is lower, but also have deficiency, because weld has obvious marks, the technology difficulty that weld seam is handled is bigger, and bearing capacity is relatively poor around the weld seam, very easily deform, influence product quality, and the polishing of welding back, both increase working strength of workers, and can cause environmental pollution again.
3, global formation, this technology is the new technology of releasing in recent years, and it adopts the way of a steel plate integral drawing to make stainless steel trough, though solved the disadvantage that welding, polishing exist, but the die cost costliness of being taken, process-cycle is long, and the raw material stainless steel materials of selecting for use is required height, and drawing process, material deformation severity, corrosion resistant plate with same thickness carries out processing and manufacturing, and the obvious attenuation of product thickness of adopting integral forming technique to make influences service life.
Summary of the invention
The objective of the invention is to overcome defective and deficiency that above-mentioned prior art exists, for make stainless steel trough provide a kind of construction cycle short, can alleviate labor strength, need not weld, polishing, material deformation be little, lower-cost contour machining procedure.
For achieving the above object, the technical solution used in the present invention is: the contour machining procedure of this stainless steel trough, comprise selected stainless steel materials, carry out panel processing: adopt press device to carry out the panel die mould by model specification stainless steel materials, form the discoid body at step-like edge, carry out the panel edge-cutting and hole-punching afterwards, make its bottom form through hole, the edge is cut smooth, carry out the panel hole flanging then, forming bottom through-hole two relative inwall and the angles between the horizontal plane is the stainless steel faceplate of α; Carry out cell body processing: stainless steel materials is carried out the cell body blanking by the model specification that is complementary with panel, carry out the cell body once drawing afterwards, form the groove of joining of band edge, and then carry out the cell body pull and stretch second time, the groove of joining that the relative outer wall of groove two and the angle between the horizontal plane are β is joined in formation, again the above-mentioned groove of joining is carried out cell body side cut, punching, make its form the stainless steel trough body that there is water falling hole at band edge center; On the edge of above-mentioned stainless steel faceplate bottom, place sealing joint strip, the stainless steel trough body of band edge is put into toward face plate center from top to down, make it to compress, form stainless steel trough.
Angle β between two relative outer walls of angle α＜stainless steel trough body and the horizontal plane makes the two tight fit between the relative inwall of described stainless steel faceplate bottom through-hole two and the horizontal plane.
Form the discoid body of left and right two disjunctors behind the described panel die mould, through panel edge-cutting and hole-punching, hole flanging, form the stainless steel faceplate of two the disjunctor through holes in bottom, after sealing joint strip was placed at the bottom through-hole edge, the stainless steel trough body of two band edges and water falling hole cooperated with it to compress and is connected to form the double flute stainless steel trough.
The described annealing in process of carrying out behind cell body blanking, once drawing, its annealing temperature can be at 1010 ℃～1060 ℃.
Stainless steel faceplate of the present invention and stainless steel trough body are processed respectively, the contour machining procedure that adopts sealing joint strip to press is mutually then made stainless steel trough, the panel of available different model, specification with join groove and arrange in pairs or groups mutually, the product of forming various models, change the traditional method of a style one mould, saved cost greatly, shortened the construction cycle of new product, and need not weld, reduced labour intensity.Adopt this processes, material deformation is minimum.
