Abstract
The present invention relates to an aramid paper honeycomb stretching tooling used in production process of large size aramid paper honeycombs in aerospace composite material field, the aramid paper honeycomb stretching tooling includes stretching frames, stretching frame fixing plates, strut fixing blocks, stretching frame struts, stretching insert prickers and the like, the stretching frames are used for stretching honeycomb lamination plates, the stretching frame fixing plates are used for fixed installation of the stretching tooling and a honeycomb stretching machine, four strut fixing blocks are symmetrically arranged on the inner side of ends of each stretching frame, the stretching frame struts are used for fixed connection between the two stretching frames, and adopt a telescopic structure, both ends are fixed in the strut fixing blocks, and the stretching insert prickers are used for fixed installation of the honeycomb lamination plates and the stretching frames. The honeycomb stretching tooling is a mounted tooling of the honeycomb stretching machine, and solves the process problems of stretching molding of the large size aramid paper honeycombs on the honeycomb stretching machine, and by cooperated use of the aramid paper honeycomb stretching tooling and the honeycomb stretching machine, rapid stretching molding of the large size aramid paper honeycombs can be realized.
Description
Technical field
The present invention relates to a kind of aramid paper honeycomb stretching tool, it is applied in the production process of aviation composite field large scale aramid paper honeycomb, and this frock is the matching tooling of honeycomb drawing machine.
Background technology
The preparation of current aramid paper honeycomb block is highly general within 300mm, stretching tool just with angle-iron frame and strut simply fixing, its stability and assembly precision poor.Large-sized aramid paper honeycomb block, such as, be of a size of long 2620mm × wide 1350mm × high 914mm, because production difficulty is large, complex process, requires high reason to the accuracy of manufacture of equipment and frock, its Development Techniques is carried out less.Matching tooling design at present for large scale aramid paper honeycomb drawing and forming is very rare, and function can not meet the production requirement of aviation large scale aramid paper honeycomb.
Summary of the invention
Lacking the problem of matching tooling in order to solve large scale aramid paper honeycomb when drawing and forming, the present invention proposes a kind of aramid paper honeycomb stretching tool.
Technical solution of the present invention is: stretching tool is made up of draw frame, draw frame fixed head, strut fixed block, draw frame strut, the plug in pricker that stretches, and is symmetrically installed with draw frame fixed head outside the longeron at the two ends of draw frame; Symmetrical installation four strut fixed blocks inside each draw frame; Described draw frame strut is made up of outer sleeve, inner sleeve, adjusting nut, regulating sleeve, and the two ends of draw frame strut are separately fixed in the strut fixed block on draw frame; The upper end that pricker 8 is inserted in stretching is circular ring structure, and lower end is tip; The depth of parallelism≤± 0.5mm between described draw frame crossbeam basal plane.
The beneficial effect that the present invention has is:
The invention provides the Large-dimension honeycomb paper honeycomb stretching tool that a kind of structure is simple, easy to operate, this frock is made up of draw frame, draw frame fixed head, strut fixed block, draw frame strut, the plug in pricker etc. that stretches.The Large-dimension honeycomb block dimensionally stable using this frock to stretch to prepare, neat appearance, hole lattice are even, the maximum drawing and forming requirement meeting long 2620mm × wide 1350mm × high 914mm honeycomb block of this frock.This stretching tool can bear the tensile load of 20 tons, between stretching tool basal plane parallel accuracy can reach ± 0.5mm within, draw frame strut adopts stretching structure, can adapt to the machine frame being fixedly connected with different length honeycomb block after honeycomb stretches, telescopic extensions can cover the stretching demand of 1200mm ~ 2000mm, 1800mm ~ 3200mm length range honeycomb block.The present invention fully meets the requirement of honeycomb stretch forming process, and the production frock that can be widely used in large scale aramid paper honeycomb is supporting.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, large scale aramid paper honeycomb stretching tool disclosed in this invention is made up of draw frame 1, draw frame fixed head 2, strut fixed block 3, draw frame strut, the plug in pricker 8 etc. that stretches.
Draw frame 1, for the stretching of honeycomb laminated plate, is symmetrically installed with draw frame fixed head 2 at the two ends of draw frame 1; Draw frame fixed head 2 is for the fixed installation between stretching tool and honeycomb drawing machine; Strut fixed block 3 is arranged on inside the termination of draw frame 1, symmetrical installation four strut fixed blocks inside each draw frame termination; Draw frame strut is made up of parts such as outer sleeve 4, inner sleeve 5, adjusting nut 6, regulating sleeves 7, for being fixedly connected with between two draw frames, draw frame strut adopts inside and outside sleeve to stretch adjustable version, and two terminations of draw frame strut are fixed in strut fixed block; Stretch and plug in pricker 8 for the fixed installation between honeycomb laminated plate and draw frame, stretching is plugged in pricker upper end and is adopted circular ring structure to be convenient to capture, and lower end is in tip process convenient insertion honeycomb laminated plate tension belt.
Concrete use operation first utilizes draw frame fixed head to be arranged on honeycomb drawing machine by two draw frame symmetries, then honeycomb laminated plate to be tensioned erect and be placed between two draw frames between two parties, again stretching is plugged in pricker to insert successively in honeycomb laminated plate tension belt and with draw frame staggered intert fixing, be stretched to after required length until honeycomb, regulate pitch-row and the adjusting nut of draw frame strut inner sleeve, draw frame strut two ends stretching is buckled ride in two corresponding strut fixed blocks, the honeycomb completed to make stretching is fixing not to bounce back, the honeycomb finally utilizing draw frame hole for hoist stretching tool and stretching to be completed hangs out stretching-machine together thus completes honeycomb stretched operation.
The method that the present invention relates to, equipment and technical scheme all belong to scope of patent protection.The invention is not limited to above-mentioned embodiment, as long as reach technique effect of the present invention based on substantially identical means, all should belong to protection scope of the present invention.
