Description
Technical field
The present invention relates to the manufacture method of the lamp ring of baking box, relate in particular 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 that the iron sheet stretching is made, because the temperature in the baking box is very high, after use a period of time, iron sheet generation corrosion has affected service life of light fixture, and the lamp ring after the corrosion looks untidy, also be the place of sheltering evil people and countenance evil practices, affected the total quality of baking box.For fear of 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 main problem that has following two aspects: the one, molding effect is bad, does not reach dimensional requirement, and the substandard products that produce in the production process are more, and easy tension crack, the production cost that has improved; The 2nd, die life is short, needs frequent repairing a die, and use cost is higher, and production efficiency is low.
Summary of the invention
The objective of the invention is the deficiency that exists 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 kind of manufacture method of baking box stainless steel lamp ring comprises the steps:
(1) cut material, according to dimensional requirement, the cutting stainless steel band;
(2) punching is carried out punching to steel band;
(3) flange carries out flange to the long limit of lamp ring and processes;
(4) tear moulding, the position-limited claw of lamp ring is torn moulding, make position-limited claw protrude steel strip surface;
(5) volume circle is rolled up circle to lamp ring and is processed;
(6) blanking welding, the lamp ring blanking that the volume circle is good, the two ends of overlap joint lamp ring, welding fabrication.
Described step 1 is carried out punching to steel band, adopts the substep punching.Because the hole that needs stamping-out of lamp ring is more, the punch-die inconvenience of arranging, simultaneously punching meeting causes blanking pressure excessive, affects die life.
Described step 3 is carried out flange to the long limit of lamp ring and is processed, in order to prevent resilience, and flange in two steps, first flange to 45 degree, again flange to 90 degree.Stainless steel material is harder, and good springiness adopts the substep flange can reduce the springback capacity of flange, makes it reach the design size requirement.
Described step 5 to lamp ring volume circle, for the ease of rolling up circle evenly, is rolled up first circle with lamp ring in advance, makes the perk of lamp ring two ends, after the volume circle is finished, carries out shaping, makes lamp ring meet dimensional requirement.Stainless steel material is harder, good springiness, and pre-volume circle makes the two ends perk be convenient to the volume circle, and shaping after the volume circle makes it meet dimensional requirement, is convenient to next step blanking and welding.
The flange of tearing moulding and step 3 of described step 4 is finished simultaneously.
For realizing goal of the invention, the present invention can also adopt following technical scheme:
A kind of manufacture method of baking box stainless steel lamp ring comprises the steps:
(1) cut material, according to dimensional requirement, the cutting stainless steel band;
(2) punching is carried out punching to steel band;
(3) tear moulding, the position-limited claw of steel ring is torn moulding, make position-limited claw protrude steel strip surface;
(4) volume circle is rolled up circle to lamp ring and is processed;
(5) blanking welding, the lamp ring blanking that the volume circle is good, the two ends of overlap joint lamp ring, welding fabrication;
(6) spinning flange carries out rotary press modelling with the lamp ring behind the welding fabrication, flange is carried out on the long limit of lamp ring process.
Described step 1 is carried out punching to steel band, adopts the substep punching.Because the hole that needs stamping-out of lamp ring is more, the punch-die inconvenience of arranging, simultaneously punching meeting causes blanking pressure excessive, affects die life.
Described step 4 to lamp ring volume circle, for the ease of rolling up circle evenly, is rolled up first circle with lamp ring in advance, makes the perk of lamp ring two ends, after the volume circle is finished, carries out shaping, makes lamp ring meet dimensional requirement.Stainless steel material is harder, good springiness, and pre-volume circle makes the two ends perk be convenient to the volume circle, and shaping after the volume circle makes it meet dimensional requirement, is convenient to next step blanking and welding.
Compare with background technology, the manufacture method of a kind of baking box stainless steel lamp ring of the present invention adopts punching, moulding, the volume circle, the blanking welding substitutes traditional drawing and forming, has improved mold use in the time of the life-span, improve production efficiency, and improved the qualification rate of product, reduced production cost; Make steel band, can adopt progressive die production, make the production automation, production efficiency is improved; Arranging of concave-convex mold is convenient in the substep punching, improved mold use in the time of the life-span, improved the quality of stamping-out; The substep flange has improved the flange quality, has reduced springback capacity; Volume circle step adopts pre-volume circle, and shaping behind the volume circle makes product meet dimensional requirement, has improved 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, lamp ring behind the welding fabrication is carried out the spinning flange, so whole flange, rotating die head one side feed pressure, make flange more even, more meet dimensional requirement, and avoided because the phenomenon of the flange outside cracking that the circle circle may cause behind the flange final step spinning flange, the lamp ring qualification rate of producing is higher, more stable quality.
