Abstract
The invention discloses an automotive interior trim hot-pressing coating technology adopting an infrared heating way. The automotive interior trim hot-pressing coating technology adopting the infrared heating way has a technical scheme that under the irradiation of a sodium halide lamp capable of generating infrared rays of 8-9 microns of wavelength, the temperature of the surface of an object to be heated is heated fast to reach 120 DEG C in three seconds (the instantaneous activationary contact temperature of glue must reach 100 DEG C), and the laminate coating of a PP (Propene Polymer) skeleton and a PVC (polyvinyl chloride) leather (the lower surface of the leather is coated with a layer of hot melt adhesive) is finished in four seconds. According to the automotive interior trim hot-pressing coating technology adopting the infrared heating way, the coating technical process can be performed continuously, the heating way is changed, and the surface of a product is heated fast to reach the required activationary temperature while the rest part of the product is kept at normal temperature, so that the strength of the product is strong enough, the product is ensured not to deform during laminating, and the instantaneous contact temperature in laminating reaches the required range. Compared to the traditional heating way, the molding cycle is short, and the deformation, caused because the heating-up period is long and the overall product is reduced in strength for rising temperatures, of the product in twice laminating is avoided.
Description
Technical field:
The invention belongs to the automotive trim heating process, specifically, relate to a kind of automotive trim infrared heating heat pressing process.
Background technology:
Traditional heat pressing process generally all is that the common heating plate is to skeleton and leather heating at present, firing rate is slow, heat time heating time is long generally all about 60 seconds, in the heating process, heated product bulk temperature all rises, and the intensity of product descends, and easily is crushed out of shape in second pressing, fraction defective is higher, and the control difficulty is large.
Summary of the invention:
The invention reside in provides a kind of zooming infrared heating mode of surface temperature process for pressing that makes.
Problem to be solved by this invention is: traditional heating is the problem that hot plate is heated to first setting, and hot plate is heated to the temperature that needs to skeleton and PVC by cross-ventilation.The efficiency of heating surface is low, and thermal loss is large, and it is long that hot plate preheats the time, inefficiency, and heated body surface non-uniform temperature.
Technical scheme of the present invention is: the skeleton that be laminated with is placed on patrix, and PVC leather (face that will fit coats PUR) is placed on the lower support frame.Sodium halogen infrared heating fluorescent tube move to skeleton and leather in the middle of energising begin heating, heat three second body surface reach predetermined temperature 120 degree (glue could activate) under this temperature.Infrared heater withdraws from, and patrix drives skeleton and moves downward rapidly the applying of finishing PVC leather and skeleton.
Wherein, the selection color of framework material is black.
Wherein, mode of heating is chosen as the sodium halogen lamp pipe heating that can produce 8～10 microns.
The invention has the beneficial effects as follows: only energising work in the needs heating of infrared lamp heating, equipment fluorescent tube in other actions of operation does not need work, greatly improved the utilization of electric energy, can save more than 50 second heat time heating time, electric energy saving 90%, only have the raising of surface temperature to avoid the distortion of product in the pressing process, improved yield 10%, greatly improved production efficiency and saved cost.
The specific embodiment:
The object of the present invention is achieved like this:
At first the selection color of framework material is black, and the object of black is fast to the infiltration rate of heat.Material at object is identical, and the weight area of heating is identical, and mode of heating is identical, and being changed to of object temperature in the heat time heating time identical situation: black material is 40 ℃ during 10 seconds heat time heating times, and white material is 35 ℃; Black material is 63 ℃ during 20 seconds heat time heating times, and white material is 54 ℃; Black material is 87 ℃ during 30 seconds heat time heating times, and white material is 71 ℃; Black material is 113 ℃ during 40 seconds heat time heating times, and white material is 90 ℃; Black material is 146 ℃ during 50 seconds heat time heating times, and white material is 115 ℃.The transformation temperature that can find out both temperature is poor from 5 degree, becomes 9 degree, becomes 16 degree again, becomes 23 degree again, and poor 31 degree that reach of end temperature are so the selection color of framework material is black.
Secondly length that is chosen as of infrared wavelength is 8～10 microns infrared wavelength, because wavelength easier and object in 8～9 microns resonates, object temperature can rise rapidly.The usual plastic material PP that uses, ABS, PC/ABS, PC, PP/PE more easily is absorbed through the infrared ray of research wavelength at 8～10 microns, and absorption efficiency is several times of other wavelength.So mode of heating is chosen as the sodium halogen lamp pipe heating that can produce 8～10 microns.
(1) skeleton that will be laminated with the leather cloth is placed on the backform, uses clip to clamp.
(2) leather or cloth (being cut into definite shape) are placed on the bracing frame.
(3) press button devices and automatically move, heater-movement heats for PVC lower surface and skeleton upper surface to centre simultaneously, and PVC and skeleton surface are heated to 120 degree in 3 seconds, and hot plate is released, and patrix moves downward skeleton and leather covers together.
(4) finish and be laminated with rear taking-up product.
Above demonstration and described basic principle of the present invention and principal character, and advantage of the present invention.The technical staff of the industry should be appreciated that; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
