Abstract
The invention belongs to aircraft manufacturing technical fields, provide a kind of clip class part by one-step bend molding apparatus.The device, including die holder, rotating bar, boss, punch-pin and bearing.In use, punch-pin is located on die holder, and rotated with rotating bar, require to determine quantity and the position of bearing by clip accessory size；During processing; section bar againsts die holder and is bonded punch-pin; one is placed in the gap of bearing and punch-pin; when rotating bar rotates, punch-pin drives section bar to be squeezed at the uniform velocity to be slided according to punch-pin outer diameter as sliding trace by bearing section bar by frictional force; until section bar is bonded completely with punch-pin; bending process terminates, and when the section bar other end is detached from bending flow, part machines.The beneficial effects of the invention are as follows clip class part by one-step brake forming is realized, improve primary hand over and examine qualification rate, improve production efficiency.
Description
Technical field
The invention belongs to aircraft manufacturing technical fields, are related to a kind of clip class part by one-step bend molding apparatus.
Background technology
Clip is an important workpiece in aircraft system, it clamps other several sub-assemblies securely, is allowed to completely close
Sealing label, which closes, keeps working condition, and bear pulling force.
When processing clip class part with traditional bending mould, due to part, when mold bending is molded, deflection is big, and zero
Also need multiple working procedure that could meet processing dimension requirement after part molding, work difficulty is big, develops clip precision one-pass molding thus
Mold by prebuckling mechanism, makes part, always in clamped condition, reduce the deformation in forming parts in forming process
Amount completes part processing through practical application one-pass molding, and reliable in quality greatly improves production efficiency.Clip woollen is in essence
When being molded in close molding die, part completes brake forming under impaction state, efficiently avoids part in forming process
Offset and interstitial hole lengthening deformation realize no surplus bending, have achieved the purpose that precise forming.
Invention content
The object of the present invention is to provide a kind of clip class part by one-step bend molding apparatus, for clip class in production and processing
The rapid processing of part, and improve primary hand over and examine qualification rate.
Technical scheme of the present invention：
A kind of clip class part by one-step bend molding apparatus, including die holder 1, rotating bar 2, boss 3, punch-pin 4 and bearing 5；
The rotating bar 2 is fixed on 4 upper end of punch-pin, and punch-pin 4 is driven to rotate；The punch-pin 4 is mounted on by round key on die holder 1,
Punch-pin 4 is freely rotated on die holder 1；The upper surface of the die holder 1 is evenly arranged multiple location holes, and location hole is along punch-pin 4
Edge arrangement；The bearing 5 is fixed on by positioning bolt in the location hole of die holder 1, and bearing 5 cooperates with punch-pin 4,
For fixed and extrudate；The boss 3 is fixedly mounted on the upper surface of die holder 1, positioned at the edge of punch-pin 4, for inciting somebody to action
Part is held up, and ensures that part is deviate from automatically.
In use, punch-pin 4 is located on die holder 1, and rotate with rotating bar 2, required by clip accessory size
Determine quantity and the position of bearing 5；During processing, section bar againsts die holder 1 and is bonded punch-pin 4, and bearing 5 and punch-pin 4 are placed on by one
Gap in, when rotating bar 2 rotates, punch-pin 4 by frictional force drive section bar using at the uniform velocity according to 4 outer diameter of punch-pin for sliding trace cunning
It is dynamic, section bar is squeezed by bearing 5, until section bar is bonded completely with punch-pin 4, bending process terminates, when the section bar other end takes off
From bending flow, part machines.
Beneficial effects of the present invention：It realizes clip class part by one-step brake forming, improves primary hand over and examine qualification rate, improve life
Produce efficiency.
Description of the drawings
Fig. 1 is the overall schematic of the present invention.
Fig. 2 is the vertical view of the present invention.
In figure：1 die holder；2 rotating bars；3 boss；4 punch-pin；5 bearings.
Specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with technical solution and attached drawing.
A kind of clip class part by one-step bend molding apparatus, operating process are as follows：
1st, die holder 1 is placed horizontally on workbench；
2nd, punch-pin 4 is connect with die holder 1 with round key, ensures that punch-pin 4 can be freely rotated on die holder 1；
3rd, rotating bar 2 is fixed on 4 upper end of punch-pin by two positioning bolts；
4th, there are four location holes, 30 degree of interval on die holder 1 to be uniformly distributed, and bearing 5 is respectively fixed by a positioning bolt
On die holder 1；
5th, boss 3 is fixed on die holder 1, and part is held up, automatic abjection.
