Abstract
The invention discloses a heating and anti-deforming process for aluminum square tubes of an ultra-wide compound machine. The aluminum square tubes are composed of the multiple first aluminum square tubes (1) and the multiple second aluminum square tubes (2). The length of the first aluminum square tubes (1) is different from that of the second aluminum square tubes (2). The multiple first aluminum square tubes (1) and the multiple second aluminum square tubes (2) are hung on a machine frame of the ultra-wide compound machine and closely abut against the upper side, the lower side and the inner side of a belt. The heating and anti-deforming process is characterized in that the first aluminum square tubes (1) and the second aluminum square tubes (2) are longitudinally arranged in a staggered mode. According to the heating and anti-deforming process for the aluminum square tubes of the ultra-wide compound machine, during machining and producing, the effect that the deformation of the aluminum square tubes of heating sections of the ultra-wide compound machine is reduced can be ensured, heat deformation of overall heated aluminum square tubes is reduced, and the aluminum square tubes extend to the two ends. In this way, the deformation of the aluminum square tubes is reduced advantageously, and the heating temperature of the surfaces of the products is consistent.
Description
Technical field
The invention belongs to continuous fiber reinforced thermoplastic composite material production field, the aluminum square tube heating anti-deformation process being specifically related in the ultra-wide compounding machine of a kind of continuous fiber reinforced thermoplastic composite material two kinds of length and being installed together.
Background technology
Along with developing rapidly of material science, advanced composite material (ACM) such as continuous fiber material is low with its density and has the mechanical performance of excellence concurrently, gains great popularity such as high hot strength, bending strength, recoverable, the excellent properties such as corrosion-resistant.Therefore, in recent years, continuous fiber composite material obtains swift and violent development, technically there has also been important breakthrough.Preparing the combination process that it is critical only that of this material, all of composite is all made by heating, pressurization, cooling three processes of molding.Heating technique is as the critical process in combination process, currently mainly it is utilized in the frame of the ultra-wide compounding machine of compounding machine the heating of the long aluminum square tube arranged, it is namely logical in the middle of the whole long aluminum square tube that to add heat pipe electrically heated, its bringing-up section generally uses the mode of the aluminum square tube (Intermediate Gray adds heat pipe) of total width, and aluminum square tube is suspended in the frame of compounding machine.Use aluminum square tube too big due to span, middle and heating temperature field, two temperature difference is relatively big, bending after being heated, directly affect in width range material surface to aluminum square tube length direction surface distance inconsistent cause being heated uneven.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of ultra-wide compounding machine aluminum square tube heating anti-deformation process, it is that aluminum square tube is installed together by two kinds of length aluminum square tubes by original overall elongated changing into, certain gap is left in centre, it is staggered in longitudinally arrangement again, to ensure that aluminum square tube will not bend because span is oversize, and after being heated, deflection is little, and deformation direction is towards both end extension.
Technical scheme is as follows: ultra-wide compounding machine aluminum square tube heating anti-deformation process, it is made up of many aluminum square tubes I and aluminum square tube II, aluminum square tube I has length two kinds different with aluminum square tube II, it is suspended in the frame of ultra-wide compounding machine, and abut against the inner side up and down of belt, it is characterised in that: described aluminum square tube I and aluminum square tube II are longitudinally staggered.
It is provided with in the middle of described aluminum square tube I and the siphunculus of aluminum square tube II and adds thermionic valves.
Described aluminum square tube I and aluminum square tube II intermediate connections leave certain gap, are provided with through hole in lateral cross section.
The present invention, it is possible in processing, it is ensured that the bringing-up section aluminum square tube deflection of ultra-wide compounding machine reduces, and arrange the thermal deformation being heated and reduce, to both end extension.So advantageously reducing the deflection of aluminum square tube, the heating-up temperature for product surface is consistent.

Detailed description of the invention
Known by Fig. 1, Fig. 2, ultra-wide compounding machine aluminum square tube heating anti-deformation process, it is made up of aluminum square tube I 1 and aluminum square tube II 2, aluminum square tube I has length two kinds different with aluminum square tube II, it is suspended in the frame of ultra-wide compounding machine, and abut against the inner side up and down of belt, the continuous fiber composite material advanced along with belt is heated, aluminum square tube I 1 and II 1 two kinds of length of aluminum square tube add up the length of the aluminum square tube reaching original structure in the direction of the width, be provided with and add thermionic valves in the middle of the siphunculus of aluminum square tube I 1 and aluminum square tube II 2.Aluminum square tube I 1 and aluminum square tube II 2 are staggered in longitudinally arrangement, and aluminum square tube I 1 is consistent in the heating-up temperature of product surface with the longitudinal bringing-up section of aluminum square tube II 2.Aluminum square tube I 1 and aluminum square tube II 2 intermediate connections leave certain gap, are provided with through hole 3 in lateral cross section, it is simple to heat radiation.
Known by Fig. 3, be the aluminum square tube structural representation of prior art.Being suspended in the heating process of compounding machine upper and lower, middle become two kinds of temperature fields with top and the bottom type, T1, more than T2, causes that aluminum square tube top and bottom temperature distortion length is inconsistent and causes bending, and the computational methods of the △ h of middle minimum bending are as follows:
△L=a*△t*L
Wherein, a: linear expansion coefficient, wherein the linear expansion coefficient a=23.2x10 of aluminum square tube-6/℃；
△ t: the temperature difference of on-the-spot test top and the bottom；
L: aluminum square tube length, △ L: aluminum square tube two sides is heated the length difference of uneven generation
B: the thickness of aluminum square tube.
Known by Fig. 4, be the aluminum square tube structural representation after temperature distortion.L1 ≈ L, L2=L1+ △ L
By arc length principle,, by L1And L2, r1And r2Bring into respectively:
=>, it is possible to derive；
Because L1 can ≈ L,
It can be seen that deflection △ h all has relation with length L and △ t, L is more long, and △ h is more big.Wherein 0 < α < 90 °
The aluminum square tube of the present invention, it is divided into two by an entirety, gap is also left in centre, so deformation can be reduced by two, the present invention is fixed in the frame of compounding machine, abuts against the inner side up and down of belt, mainly the continuous fiber composite material advanced along with belt is heated, make its homogeneous heating, provide condition for follow-up pressurization, cooling molding.
