Abstract
The invention discloses a synchronous manufacturing method for main and auxiliary hinge leaves. The method comprises steps as follows: firstly, strip steel is punched into a planar plate in the unfolded shape of integrated hinge shafts and hinge pieces by the aid of a punching machine; a bearing position gap is cut in one side of the planar plate; through pre-bending, semi-bending and bending molding, the hinge shaft parts in the first step are integrally coiled into the approximately cylindrical shape, then the strip steel plate with one side bend-molded to be cylindrical is partitioned and cut into multiple plates provided with hinge shafts according to the outside dimension requirements of main hinges, and auxiliary hinge leaves are cut from the plates according to the dimensions. The hinge shafts of the main and auxiliary hinge leaves are bent and produced synchronously; compared with the separated manufacturing method for the main and auxiliary hinge leaves, the method can increase the coaxiality of the hinge shafts of the main and auxiliary hinge leaves and reduce inflexible rotation of the hinges due to the poor horizontal linearity of the hinge shafts; and compared with the traditional technology, the method has the advantages that the relatively great cost can be saved, the production efficiency can be doubled, and the yield is high.
Description
Technical field
The present invention relates to hinge manufacture field, more particularly to a kind of synchronous mode manufacture method of primary and secondary leaf of hinge.
Background technology
Primary and secondary hinge cylinder includes leaf of hinge and hinge axis, and it is mainly characterized by leaf of hinge and is divided into subpage piece and female hinge,
Subpage piece is mounted on hinge axis and is formed chain connection with female hinge, and all in the same tangential direction of hinge axis, son
A part for the female hinge " emptying " of hinge likeness in form, subpage piece around 360 ° of rotations of axis, and be able to can be fitted among female hinge, formed
A complete hinge.Compared to being opened flat hinge, primary and secondary hinge in doorframe the placed in the middle, depth, keep to the side to be suitable for installing, it is not necessary to
The position (fluting) that door leaf fixes hinge, doorframe and door wing gap size reasonable are drawn as being opened flat hinge, entirety is not destroyed
Aesthetic, it is quick for installation, convenient.
Primary and secondary hinge during fabrication, generally using inside and outside hinge two panels separate type production method, then through a series of
Loaded down with trivial details step, end product assembling.Not only manufacture process is loaded down with trivial details, and production efficiency is low, and easily occurs due to batch not
There is the big problem of aberration with surface treatment such as plating, the spraying of caused subpage and female page, especially separate type is produced
Method easily makes spool horizontal linearity poor, rotates dumb and flatness poor.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of synchronous mode manufacture method of primary and secondary leaf of hinge is provided.
The present invention for achieving the above object, is employed the following technical solutions：A kind of synchronous mode manufacture method of primary and secondary leaf of hinge,
Characterized in that, its step is as follows：
(1) punching press：Strip is punched into the flat sheet of hinge axis and the expansion shape of leaf of hinge one using punch press；
(2) bearing position is cut：Bearing is determined in the side of flat sheet, i.e. the hinge shaft portion in hinge by design interval
Position breach；
(3) pre-bend：The hinge shaft portion sheet material after the breach of bearing position will be determined in step (2) using punch press and mould whole
Body is rolled into semi-cylindrical；
(4) half bendings：To be pre-folded in step (3) using punch press and mould curve semi-cylindrical hinge shaft portion it is overall after
It is continuous that to be rolled into 3/4ths cylindrical；
(5) bending and molding：The hinge axle portion of 3/4ths cylinders will be partly bent into step (4) using punch press and mould
Entirety is divided to continue to be rolled near cylindrical；
(6) integer：Bending and molding in step (5) is designed into the hinge shaft portion entirety integer of near cylindrical in regulation
Cylinder；
(7) separation is cut：To side, band steel board of the bending and molding in cylinder is entered by female hinge external dimensional requirements
Row piecemeal cuts into multiple plates with hinge axis, then cuts out sub- leaf of hinge by size on each plate, then cut out
Remaining plate is female leaf of hinge after sub- leaf of hinge；
(8) antithetical phrase leaf of hinge, female leaf of hinge carry out die mould correction.
Particularly, strip is made by cold-strip steel or strip steel hot rolling process in the step (1), wherein cold-strip steel work
Skill step is：Pickling-rolling-annealing-rolling size synchronously lubricates-upper antirust oil-smooth scale-polishing-packaging；Hot-strip
Processing step is：Heating furnace-dephosphorizing machine-cold-coiling machine-the baler-of roughing mill-dephosphorizing machine-finishing mill-surface quality inspection instrument-layer
Jetting device for making number-item pool slab.
The invention has the beneficial effects as follows：Primary and secondary leaf of hinge synchronous production in the present invention, hinge axis are Synchronous Bending, compare son
The manufacture of female hinge separate type, this method is conducive to improving the axiality of primary and secondary leaf of hinge hinge axis, reduces due to hinge
Hinge rotates dumb caused by shaft horizontal line difference, and compares traditional handicraft and can save larger cost, make production efficiency
Multiplication, high yield rate.
