Abstract
The invention is concerned with the compression composition equipment of breaking thermal bridge steel section steel, which can solve the problem that steel section steel is high bounce ad not easy to knitted together with plastic, the steel plastic composition section steel is low production work efficiency and high equipment cost. It is: uses a pair of expression rolls with synchronizing different-direction rotation to extrude the softening plastic into the obligate groove of the steel section steel, in order that the steel and the plastic can pack with each other; the space of the expression roll, the vertical and the horizontal positions can adjust, sets several expression roll with different switching on the product line to pressure times to the plastic steel section steel in order to composition forming. The invention is with better heat insulation effect, high producing efficiency of flow production, simple equipment structure.
Description
Technical field: the present invention relates to the manufacturing installation of composite steel profile for door and window, particularly the pressurized composite apparatus of insulated bridge steel window and door sectional material.
Technical background:
The steel casement door window almost ruled all the land in the 70-80 age in 20th century, the nineties aluminum window, steel sash, plastic window three minutes all over the world, enter 21 century steel casement door window owing to be subjected to the restriction of product heat-conductive characteristic, market is atrophy gradually.Vigorously advocate in the government and the whole society under macroscopical background of " energy savings " and " sustainable development ", the building doors and windows of all kinds all can not be avoided the big technical policy background of country-driven energy savings, plastic door-window is because of the heat insulation advantage of its material, take the lead in stepping into the threshold in energy saving door and window market, but its intensity is not high, easily aging and distortion; Aluminum alloy doors and windows utilize the characteristics of its section bar easy-formation, have developed composite heat insulation section, taken the admission ticket in market, but cost are higher, the resource relative shortage; The steel casement door window can only be free between the slit, market owing to go back the bridge insulation thermal resistance section bar technology of neither one maturation, fails to give full play to its effect.
Because steel density is 7.8 (g/cm
3), tensile strength is 300-400 (Pa/m
2), yield strength is 230-330 (Pa/m
2), percentage elongation is 28-32%, and elastic modelling quantity is 210Gpa, and linear expansion coefficient is 1.25 X10-5 (K-1), and the material characteristic that these are good is that other material is not available in the market, is the basis that guarantees doors and windows availability and entity quality.Steel can be realized recycling, can not bring environmental pollution in the use, are environmental protection building materials.China is the country of world steel production capacity maximum, and product resource is very abundant.Plastics are cheap heat-barrier materials, therefore, develop the composite steel profile for door and window of the bridge insulation thermal resistance that is made of steel profile and plastics, are the key points of making high-quality low-cost and environment-friendly type steel casement door window, have vast market prospect.
The technological difficulties of making the steel window and door sectional material of bridge insulation thermal resistance be to solve steel profile with its in the middle of the compound problem of heat-barrier material of plastic material etc., the yield strength that comprises steel is high and be difficult for processing and the linear expansion coefficients of steel are little and problem that the plastic deformation coefficient is big.Existing technology of producing the bridge insulation thermal resistance composite steel profile for door and window is to adopt the cold forming processing technology, is that clod wash is rolling to be out of shape it by steel are carried out, and realization is compound with heat-barrier material.It as application number " steel window and door sectional material break heat bridge " patent of 02235094, the structure of the disconnected heat bridge of disclosed a kind of steel window and door sectional material, the steel profile that is two cold rolling moulding is an opening form, two ends are shaped on notch, the linear direction of edge is shaped on taper platform interruption, that be evenly distributed in advance, and taper platform one side is an arcwall face; Vertically separate with aluminium sheet between two engineering plastics connecting plates, its two ends are shaped on groove and the identical groove of taper platform that slows down resilience; The steel profile notch is reserved with the gap that cooperates with connecting plate, during composite molding, the steel profile notch is inserted at the connecting plate two ends respectively, under the effect of compounding machine barrel roll, edger roll and gradual change friction-type core bar with principal mode material and firm being interlocked of connecting plate.And for example application number is the patent of 03211124 " heat insulating board steel section bar and door and window ", disclosed a kind of heat insulating board steel section bar, be by shape and non-metallic material is compound constitutes, the connector that conducts as blocking-up metal thermal source with non-metallic material between two shapes, the link slot that is provided with respectively on the both side ends of this connector and the corresponding inside line of two shapes matches, and this connector is by the link slot and the rolling formation integrally insulating insulation of the shape composite material of two shape inboards.Publication number is CN1401876A for another example, the patent of invention of " composite steel-plastic sections and manufacture method thereof " by name, manufacture method comprises system steel lining, steel-plastic coextrusion and surface treatment three phases, wherein makes steel lining and is the heat insulation connector that is " worker " font by the cross section and connect two independently steel profile shapes in the mode of wearing bar or by hot melt polyurethane in the mode of building.
Have following defective in the above technology, the door-window section bar that the co-extrusion mode is made because steel is interior, plastics outside, door and window add man-hour invar with plastic shrink than different, and section bar otch steel lining is exposed, strengthened the door and window manufacture difficulty, work efficiency is difficult to improve; Employing is worn the bar mode and is made steel plastic door and window section bar, is unfavorable for continuous productive process, and work efficiency is low; Adopt cold rolling, the mode of colding pressing, the coefficient of resilience height of invar can't be combined closely plastics and steel profile; The employing mode of building is made composite steel-plastic sections, mould and die accuracy and injection pressure had relatively high expectations, and the equipment investment costliness, energy resource consumption is big.
Summary of the invention:
The composite material that the objective of the invention is to avoid above-mentioned the deficiencies in the prior art and a kind of manufacturing is provided firmly, the pressurized composite apparatus of production work efficiency height, manufacturing insulated bridge steel window and door sectional material that equipment cost is low.
