Description
Technical field
The present invention relates to the manufacture method of the lamp ring of baking box, particularly relate to a kind of manufacture method of baking box stainless steel lamp ring.
Background technology
What the lamp ring of the baking box of prior art adopted is, and iron sheet stretches makes, because the temperature in baking box is very high, after using a period of time, iron sheet generation corrosion, have impact on the service life of light fixture, and the lamp ring after corrosion looks untidy, also be the place of sheltering evil people and countenance evil practices, have impact on the total quality of baking box.In order to avoid the corrosion of baking box lamp ring, improve the service life of light fixture and the total quality of baking box, the material of lamp ring adopts stainless steel.Because stainless material hardness is high, ductility is poor, adopts drawing and forming, the problem of two aspects below main existence: one is that molding effect is bad, and do not reach dimensional requirement, the substandard products produced in production process are more, and easy tension crack, the production cost that improve; Two is that die life is short, and need frequent repairing a die, use cost is higher, and production efficiency is low.
Summary of the invention
The object of the invention is the deficiency existed for prior art, provide a kind of production efficiency high, production cost is low, and the manufacture method of the high baking box stainless steel lamp ring of qualification rate.
For achieving the above object, the present invention can adopt following technical scheme:
A manufacture method for baking box stainless steel lamp ring, comprises the steps:
(1) material is cut, according to dimensional requirement, cutting stainless steel band;
(2) punching, carries out punching to steel band;
(3) flange, carries out flange process to the long limit of lamp ring;
(4) tear shaping, tear shaping to the position-limited claw of lamp ring, make position-limited claw protrude steel strip surface;
(5) volume circle, rolls up circle process to lamp ring;
(6) blanking welding, will roll up the lamp ring blanking justified, the two ends of overlap joint lamp ring, welding fabrication.
Described step a pair steel band carries out punching, adopts substep punching.Need the hole of stamping-out more due to lamp ring, punch-die arrangement inconvenience, punching simultaneously can cause blanking pressure excessive, affects die life.
Described step 3, carries out flange process to the long limit of lamp ring, and in order to prevent resilience, flange in two steps, first flange is to 45 degree, then flange to 90 is spent.Stainless steel material is comparatively hard, good springiness, adopts substep flange can decrease the springback capacity of flange, makes it reach design size requirement.
Described step 5, to lamp ring volume circle, for the ease of rolling up circle evenly, first carrying out pre-roll circle, lamp ring two ends is tilted, after volume has been justified, having carried out shaping, make lamp ring meet dimensional requirement by lamp ring.Stainless steel material is comparatively hard, good springiness, and pre-roll circle makes two ends tilting be convenient to volume circle, and shaping after volume circle, makes it meet dimensional requirement, be convenient to next step blanking and welding.
Tearing of described step 4 shapingly completes with the flange of step 3 simultaneously.
For realizing goal of the invention, the present invention can also adopt following technical scheme:
A manufacture method for baking box stainless steel lamp ring, comprises the steps:
(1) material is cut, according to dimensional requirement, cutting stainless steel band;
(2) punching, carries out punching to steel band;
(3) tear shaping, tear shaping to the position-limited claw of steel ring, make position-limited claw protrude steel strip surface;
(4) volume circle, rolls up circle process to lamp ring;
(5) blanking welding, will roll up the lamp ring blanking justified, the two ends of overlap joint lamp ring, welding fabrication;
(6) spinning flange, carries out rotary press modelling by the lamp ring after welding fabrication, carries out flange process to the long limit of lamp ring.
Described step a pair steel band carries out punching, adopts substep punching.Need the hole of stamping-out more due to lamp ring, punch-die arrangement inconvenience, punching simultaneously can cause blanking pressure excessive, affects die life.
Described step 4, to lamp ring volume circle, for the ease of rolling up circle evenly, first carrying out pre-roll circle, lamp ring two ends is tilted, after volume has been justified, having carried out shaping, make lamp ring meet dimensional requirement by lamp ring.Stainless steel material is comparatively hard, good springiness, and pre-roll circle makes two ends tilting be convenient to volume circle, and shaping after volume circle, makes it meet dimensional requirement, be convenient to next step blanking and welding.
Compared with background technology, the manufacture method of a kind of baking box stainless steel lamp ring of the present invention, adopts punching, shaping, volume circle, blanking welds, and substitutes traditional drawing and forming, while improve the mold use life-span, improve production efficiency, and improve the qualification rate of product, reduce production cost; Make steel band, progressive die can be adopted to produce, and make the production automation, production efficiency is improved; Substep punching, is convenient to the arrangement of concave-convex mold, while improve the mold use life-span, improves the quality of stamping-out; Substep flange, improves flange quality, reduces springback capacity; Volume circle step adopts pre-roll circle, and shaping after volume circle, makes product meet dimensional requirement, improve the qualification rate of product.The manufacture method of another kind of baking box stainless steel lamp ring of the present invention, flange is placed on final step, spinning flange is carried out to the lamp ring after welding fabrication, so overall flange, a rotating die head feed pressure, make flange more even, more meet dimensional requirement, and avoid because enclose the phenomenon ftractureed outside flange that circle may cause after flange, final step spinning flange, the lamp ring qualification rate produced is higher, and quality is more stable.
