And aluminum profile, after bending forming, car body matching requirements are often not achieved in the product quality and dimensional accuracy of component, need to structure
Part carries out adjusting shaping.The most commonly used is traditional three-point bending adjusting device in production, schematic diagram is shown in Fig. 3.In the device, to
The component outer profile of adjusting leans against in two back-up roller wheels, with its Internal periphery of hydraulic cylinder top, so that component is occured bending and deformation, directly
Meet required precision to outer profile, belongs to a form adjustment manner.But this method can make the Internal periphery material bending of component
It is pressurized, Instability wrinkling often occurs, especially for the lesser component of wall thickness, wrinkling is particularly acute, and eventually leads to structure
Part can not normal use.
In view of the above problems, the invention proposes a kind of aluminium profile member contour accuracy adjusting devices, by gradually increasing
The wall thickness in component Internal periphery region, the mode for shortening Internal periphery length make component generate bending deformation, until outer profile precision is full
Foot requires, and belongs to progressive form adjustment manner.The device can effectively eliminate ridging defect caused by above-mentioned traditional three-point bending method
The problems such as, to improve the adjusting quality of aluminium profile member.
Summary of the invention:
The present invention provides a kind of aluminium profile member contour accuracy adjusting device, it is therefore intended that solves structure in traditional adjusting device
The problems such as part easy Instability wrinkling.
Above-mentioned purpose of the invention is realized by the following method, as follows now in conjunction with Detailed description of the invention:
Adjusting device of the present invention includes 1.C type frame platform；2. hanger bracket；3. oil cylinder；4. compression bar；5. pressing plate；6.

Bolt；9. pedestal.Collet 7-4 is divided into upper and lower two groups of symmetrical collets, aluminium profile member is placed on lower collet first, oil cylinder 3 is simultaneously
Two sides upper grip downlink, the two sides of upper and lower two pairs of collet clamping components are pushed, and are closed up in horizontal direction simultaneously, are located at two pairs
Part construction material among collet cohesion, thickness due to level is pressurized are increased slightly, and length slightly shortens, component thus to
Inside generates slight curves deformation, when 3 backhaul of oil cylinder, lifts upper grip, unclamps aluminium alloy element, upper and lower collet is respective
The spring effect of tail portion is lower to be resetted.It constantly repeats the above process, the component deformation extent that curves inwardly gradually increases, until profile essence
Degree is met the requirements.
In the adjusting device, Tiao Xing mechanism 7 mainly by connecting rod rack 7-1, push and pull system 7-2, hinge bolt 7-3 and
Collet 7-4 composition, wherein connecting rod rack 7-1, push and pull system 7-2 and collet 7-4 carry out Dynamic link library by hinge bolt 7-3,
The two sides of upper and lower two groups symmetrical collet clamping components, and horizontal direction simultaneously are driven in the driving lower link system 7-2 of oil cylinder 3
Inside close up.
In the adjusting device, pressing plate 5 and compressed spring 6 form upper compensation mechanism, and pedestal 9 and compressed spring 6 form
Lower compensation mechanism, when push and pull system 7-2 drives collet 7-4 to will lead to the compressed spring 6 in upper and lower compensation mechanism when inwardly closing up
Contraction distortion, compressed spring 6, which then discharges deformation, when 3 backhaul of oil cylinder can make upper and lower two pairs of collets reset, to play movement
The effect of compensation.
In the adjusting device, hanger bracket 2 and compressed spring 6 form position-limit mechanism, prevent Tiao Xing mechanism 7 from position occurred
Move and change the motion path of push and pull system 7-2.
Compared with traditional adjusting device, adjusting device of the present invention has many advantages, such as: by adjusting aluminum profile
The position of component is maintained at the center of oil cylinder 3 and component on same horizontal linear, guarantees that component is not sent out during adjusting
Raw offset, while collet 7-4 is capable of the two sides of clamping component, and component is prevented to be flipped during adjusting；Adjusting dress
It sets and belongs to progressive form adjustment manner, by gradually increasing the wall thickness in component Internal periphery region, the mode for shortening Internal periphery length makes structure
Part generates bending deformation, and until outer profile precision is met the requirements, the generation of reduction material buckle in compression, surface wrinkling can be significantly
Improve the contour accuracy of aluminium profile member.
