Abstract
The present invention discloses a metal plate arc bending forming method and belongs to the technical field of metal plate bending. The method comprises the following steps: A, evenly dividing an arc, i.e., dividing the arc into n segments from the center of the arc evenly and symmetrically on two sides; B, determining a chord length bending angle of each evenly divided arc segment; C, reserving one positioning connecting element at each of two sides of an arc part unfolded material for positioning during bending; D, determining an order of bending for the n arc segments and carrying out bending; and E, removing the positioning connecting elements after bending forming. A guarantee is provided on continuity of joining design and processing, and an improvement in the processing quality of parts is achieved.
Description
Technical field
The present invention relates to panel beating brake techniques field, in particular to a kind of panel beating circular arc bending and molding method.
Background technology
In panel beating, being frequently encountered the Bending Processing of circular arc part, the size of this kind of circular arc part R is as zero
The difference of part structure and different.The bending method of such part generally similar be typically all use shaping dies bending and
Become, i.e. according to treating that the circular arc R size of bending and forming part uses suitable circular arc mold to carry out bending and molding.Although it is the most square
Just, but owing to the deformation of metal rebounds, formation of parts circular arc R precision can be caused the highest.And arc mould typically can only be processed
The circular arc part bigger than oneself arc size, and only both sizes closer to time, part forming effect is the best.Shaping dies
Poor universality, the range of work are narrow, cost is high, often limit designer big to part bent arc R in design process of parts
Little selection, even sometimes has to change structure, abandons the selection to circular arc part.
Summary of the invention
It is an object of the invention to provide the panel beating circular arc bending and molding method of the most general a kind of similar circular arc, to solve
Certainly the problems referred to above.
For realizing the object of the invention, the technical scheme of employing is: a kind of panel beating circular arc bending and molding method, including following step
Rapid:
A. by circular arc decile, from center of arc, point both sides are symmetrical, and circular arc is divided into n section；
B. the circular arc chord length bending angle of each section of decile is determined:
C. each reserved one piece of positioning link on the both sides of circular arc part spread material, is used for the location when bending and uses；
D. determine the bending order of n section circular arc, carry out Bending Processing；
E. after bending and molding, positioning link is removed.
Further, taking chord length is that 2mm carrys out decile circular arc.
Further, positioning link and circular arc spread material length are equal, and width is 20mm.
The invention has the beneficial effects as follows, change Qu Weizhi, solve the Bending Processing problem of circular arc sheet metal component, it is ensured that design
With the seriality of processing linking, improve the crudy of part.Positioning link is utilized to ensure that circular arc part each time
Bending is all straight line location, registration.
Detailed description of the invention
Below by specific embodiment, the present invention is described in further detail.
The panel beating circular arc bending and molding method that the present invention provides, comprises the following steps:
A. by circular arc decile, from center of arc, point both sides are symmetrical, and circular arc is divided into n section；Desirable chord length is that 2mm carrys out Equal round
Arc.From center to both sides decile.B. determine that the circular arc chord length bending angle of each section of decile: C. is the two of circular arc part spread material
The each reserved one piece of positioning link in limit, is used for the location when bending and uses；Positioning link and circular arc spread material length are equal, wide
Degree is 20mm, and the bending each time making circular arc part is all straight line location.D. determine the bending order of n section circular arc, roll over
Curved processing；E. after bending and molding, positioning link is removed.
When the circumferential angle corresponding to circular arc is infinitely small, its chord length is equal to arc length, namely straight length is equal to curve
Length, profit in this way, is machinable some sections the Arc Subdivision after bending and forming, when the every segment of curve is got enough
Hour, straight length is equal to length of curve, so circular arc bending is decomposed into the straightway bending that circular arc is a bit of
Combine.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
Claims (3)
