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.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, the angle that forms between the relative inwall of bottom through-hole two 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 angle that formation is joined between the relative outer wall of groove two is the groove of joining of β, 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 between the relative inwall of described panel bottom outlet two＜join groove makes the two tight fit.

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.

The specific embodiment

Select suitable stainless steel materials, carry out the panel processing of stainless steel trough:

(1) panel die mould, select corresponding casted die mould for use by the design model specification, and with more than the nominal pressure 4000KN, moulding on the above hydraulic press of hydraulic die cushion power 2000KN, form as shown in Figure 1, the edge is step-like discoid body, can be the disjunctor discoid body also, the reinforcement of oriented upper process on the edge.

(2) panel edge-cutting and hole-punching, with the panel behind the above-mentioned die mould just base adopt nominal pressure 3000KN above hydraulic press or pressing equipment with corresponding mould, form as shown in Figure 2, through hole is arranged at the bottom, cuts off along the first base of the panel of reinforcement.
