Detailed description of the invention
In aftermentioned embodiment, hot pressing principle is mainly that heat energy is passed to cut-parts via mould, makes it sizing, or makes two cut-parts weldings.Welding utilizes energy by two or many material combinations in addition, the mode of logical heat transfer allows face of weld reach its activation temperature, and utilize positive pressure to make face of weld after solidifying, produce mechanical bond power in boundary zone, and the transmission of two face of weld Yin Gaowen, make molecule absorption energy and produce intermolecular force, and then make two cut-parts produce enough bond strengths.
In one embodiment of this invention, in heat transmission, the generation of heat is to make electric energy be converted to heat energy by electric control system controls electrothermal tube.Electric-control system has automatically controlled interface, and it comprises Temperature Setting, holds pressure time and various starting switch.
As shown in Figure 1 to Figure 3, in one embodiment of the invention, the set of molds of hot-pressing system comprises mold 10 and bed die 11, and the body of upper and lower mould is all cast by aluminium, and the overall size of upper and lower mould is depending on concrete knapsack torn size.
Mold 10 is mainly used in the transmission of heat energy, mold is built-in with equally distributed many electrothermal tubes, and be connected with electric-control system, set the temperature needing by the automatically controlled interface of electric-control system, projecture outside slide fastener, the clasp etc. in knapsack front in hot pressing, the central authorities of mold 10 become cavity 100, and inner side, edge has hollow out position 101.The bottom of mold 10 is the hot pressing circle 102 of an annular, and hollow out position 101 does not extend to hot pressing circle 102.In conduction principle due to heat transmission, heat is passed to low-temperature region by high-temperature area, and for making heat transfer efficiency high and quick, the material of mold 10 has adopted gradient type configuration, adopt red copper at the mold that plays direct heat pressure surface, instant heating trim ring 102 adopts red copper.Due to the preferably metal material of thermal conductivity of red copper, and the requirement of temperature stabilization is very important in hot pressing principle, therefore adopt red copper in the mould contact surface of being responsible for hot pressing, the engagement edge of the hot pressing face of red copper mold is rounded, to avoid fabric when the pressing to produce heavier impression.
The body of bed die 11 is also to be cast by aluminum dipping form, and the upper surface 110 of bed die 11 is a plane, and upper surface 110 is its hot-pressed surface, and bed die 11 also has annular sidewall 111.In bed die 11, be provided with air channel 112, air channel 112 connects air draft system.Hot-pressed surface 110 outer rings of bed die 11 and the sidewall of bed die form respectively equally distributed multiple wind inlet 114.Each wind inlet 114 is communicated with air channel 112.By air channel 112, wind inlet 114, the wind power energy of air draft system reaches absorption and is sleeved on the cut-parts on bed die 11 and makes the accurately effect of location of cut-parts.
On the upper surface 110 of bed die 11, according to the position of the outer projecture such as clasp, slide fastener of cut-parts, form respectively hollow out 115, when avoiding pressing, outer projecture is damaged.Because partial portion in cut-parts is multilayer cut-parts stacks, the Thickness Ratio remainder thickness of stack place good thick go out many, when making pressing, upper and lower mould can be completely closely sealed, at the thicker position of corresponding cut-parts, bed die 11 is recessed to form groove 116 downwards, groove 116 is built-in with hard gel sheet or silica gel strip 117 (as shown in Figure 9), the space that utilizes groove to abdicate, and by the pliability of silica gel piece, allow pressing process be unlikely to because of the incomplete situation of the excessive generation welding of high low head.
In one embodiment of this invention, mold 10 is to be driven by a baric systerm, and baric systerm is responsible for supplying with pressure in hot pressing, and sufficient source of the gas air pressure significantly promotes the stability of heat pressing process.
Set of molds shown in Fig. 1 to Fig. 3 is to be placed on work table, and the pedestal of work table is stable, and is positioned over smooth bottom surface, and whole hot-pressing forming system is to be placed on to provide dry and the good place of scavenging performance.
For air draft system, the concrete structure of baric systerm and electric-control system has not just been spoken more, and it can adopt commercially available prod formation of structure in an embodiment of the present invention.Below in conjunction with the embodiment shown in Fig. 1 to Fig. 3, hot press forming technology is described.
In one embodiment of this invention, as shown in figure 11, the hot press forming technology of knapsack comprises step 301, step 302 and step 303.
As shown in Figure 4, in step 301, mode of operation is enclosed within on bed die 11 after reverse by inside and outside outer ring cut-parts 40, cut-parts 40 edges are in alignment with the position line on bed die 11, the manual upper surface 110 that the top edge of cut-parts 40 is pressed to bed die 11, and utilize air draft system to adsorb cut-parts 40 by means of wind inlet 114, make cut-parts 40 docile on bed die 11.
As shown in Figure 5, utilize mold 10 that the outer ring cut-parts 40 that are positioned on bed die 11 are directly carried out to hot pressing, just can complete the sizing of bound edge 401.
As shown in Figure 7, finally obtain the knapsack cut-parts 60 (shown the front of cut-parts in figure, compared with shown in Fig. 6, interior outside is reverse) of fusion molding.
In step 303, the facing up of knapsack cut-parts 60, heat insulating board on pad just can complete and guarantee seamless heat seal strength and the overall appearance of knapsack body after hot pressing again.
As shown in Figure 8, in another embodiment of the present invention, when outer ring cut-parts 40 are positioned, for thicker or relatively hard fabric, can there is larger gap in the hot-pressed surface of cut-parts edge and bed die, therefore be difficult to completely be adjacent to and be positioned at bed die by air draft system, after air draft system is opened, the transparent PET sheet 70 of a slice heatproof that tiles in cut-parts 40 again, PET sheet 70 not only can make air draft system because absorption PET takes advantage of a situation, cut-parts be overlayed on mould, more can avoid fabric Yin Gaowen pressing and variable color or impaired, and clear PET sheet 70 is also convenient to observe in position fixing process, whether the position adjustment of the back gauge of cut-parts and the fold of corner produce.
As shown in Figure 9, in another embodiment of the present invention, in step 301 and/or 302, on bed die 11, be placed with woven wire 90, the 80 object web frames that woven wire 90 is for example made up of stainless (steel) wire and copper mesh, the wind power energy of air draft system directly reaches absorption cut-parts 40 by woven wire 90 like this, the accurately object of location cut-parts, again because the areola density of woven wire 90 is high, can not produce hole vestige because pressure makes fabric, and adopt two kinds of unlike material silk screens to form, can utilize the hardness substrate of stainless (steel) wire and outside copper mesh is coated it, make its receipts limit more smooth-going, and the thermal conductivity of copper material, also can make the heat conduction of fusion process transmit more complete.
