Accompanying drawing explanation
Fig. 1 alternative embodiment is rolled up the structural representation of braking club;
The processing process figure of metal corrugated sandwich boards in Fig. 2 alternative embodiment.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail.
The volume brake apparatus of the present invention adopts volume braking club to substitute the gear of conventional roll brake apparatus.
In embodiment, volume brake apparatus includes volume braking club, motor, decelerator and sprocket wheel. Wherein, as it is shown in figure 1, volume braking club is provided with at least one roller to 1 with for the support rollers support 2 to 1. Roller includes to 1 that two profiles are identical, the roller of upper and lower parallel placement, and the two ends of roller are supported on support 2.
Roller is equidistantly distributed vertically multiple concaveconvex structure, and each projection is in the form of a ring around the outer circumferential walls of described roller; The groove location formed between two adjacent protrusion of the roller of upper and lower parallel placement, the projection of any one roller and another roller, forms meshing relation; Protruding is shaped as polygon or circular arc.
Volume braking club is provided with multiple roller pair, and along charging aperture 3 to the direction of discharging opening 4, the Concha Arcae number of teeth of roller is gradually increased. If roller logarithm is n, then the Concha Arcae number of teeth of corresponding roller is 2n-1, wherein n >=1.
Motor electrically connects with decelerator, and decelerator is for reducing the rotating speed of motor, and decelerator and sprocket wheel are connected by chain, and the axle head of each roller is provided with sprocket wheel.Motor drives decelerator to rotate, and decelerator drives many group sprocket wheel synchronous axial system by Chain conveyer, thus realizing the rotation of roller.
Sheet material enters to roll up brake apparatus, and this volume brake apparatus adopts formula volume lock principle difficult to understand, prepares the volume braking club of different model according to the length of side of Concha Arcae, processes Concha Arcae central layer by rolling up lock continuously. Formula volume lock principle difficult to understand: sheet material is the also and then change of the size in its fold direction while molding, sheet material itself will not be caused stretching when sheet material forms Concha Arcae; And existing Concha Arcae manufacture method is to adopt punching press principle to stamp out valley of corrugation, corrugated sheet can be stretched and cause damage. If roller logarithm is n, then discharging opening can roll up the Concha Arcae number of teeth that lock goes out is 2n-1, wherein n >=1.
Sheet material is by repeatedly volume lock through each group of roller after pay-off access arrangement, do not need material is carried out to stretch and can directly roll up lock and go out qualified Concha Arcae central layer, this technique can produce continuously, has to pass through the qualification rate that the processing technique of mold pressing trimming more can be saved the time, is more conducive to production in enormous quantities, more can guarantee that in size and specification after more existing rolling.
This volume brake apparatus can ensure the concordance of the flatness of material, uniformity and material, it is also ensured that corrugated shape highly consistent. The problem that can not form fine and close seam face in later stage soldering operation is caused because of the damage that plate stretch is caused and Concha Arcae irregular it addition, also solve in traditional manufacturing technique.
As in figure 2 it is shown, be the processing process figure of metal corrugated sandwich boards in the present invention. The processing method of metal corrugated sandwich boards comprises the following steps:
S11: sheet material and panel surface preparation, wipe oil and oxide-film;
Wherein, the surface of sheet material and panel is carried out pretreatment, to remove greasy dirt and the oxide-film of sheet material and panel surface. Sheet material can select corrosion resistant plate, carbon steel sheet, aluminium sheet or copper coin, and the thickness of sheet material is 0.2��5mm; Panel selects aluminium sheet, carbon steel sheet, corrosion resistant plate or copper coin, and the thickness of panel is 0.5��15mm.
S12: pretreated sheet material and panel are sent into the solder machine that is coated with or rolling solder, gives coating solder or rolling solder on the contact surface of sheet material and panel respectively.
Wherein, solder is the metal class solder of tabular, banding or paste, and this solder is hard solder. Preferably, metal class solder is aluminum-silicon (Al-Si) solder. Run and be coated with solder machine or milling train, solder is fixed on the two sides of sheet material and the side of panel.
S13: the sheet material scribbling solder is sent into the volume brake apparatus in above-described embodiment, processes Concha Arcae central layer by rolling up lock continuously;
Wherein, the corrugated shape of Concha Arcae central layer is polygon or circular arc. In the present embodiment, corrugated shape is half regular hexagon, and hexagonal length of side is 2��100mm.
Sheet material is through each repeatedly volume lock organizing roller of volume brake apparatus, do not need sheet material is carried out to stretch and can directly roll up lock and go out qualified Concha Arcae sheet material, this technique can produce continuously, has to pass through the qualification rate that the processing technique of mold pressing trimming more can be saved the time, is more conducive to production in enormous quantities, more can guarantee that in size and specification after more existing rolling.
This volume brake apparatus can ensure the concordance of the flatness of material, uniformity and material, it is also ensured that corrugated shape highly consistent.
The problem that can not form fine and close seam face in later stage soldering operation is caused because corrugated sheet being stretched the irregular of the damage caused and Concha Arcae it addition, also solve in traditional manufacturing technique.
S13: by electrostatic spraying, makes scaling powder be evenly applied to Concha Arcae core plate surface, effectively to remove out oxide-film, it is to avoid produce rosin joint during soldering.Scaling powder is common scaling powder.
S14: two attached panels of outer surface of the Concha Arcae central layer one layer or two stackings put, as the sandwich corrugated sheet not welded after being well placed;
Wherein, when the quantity of Concha Arcae central layer is two-layer, two-layer Concha Arcae central layer stacks according to the direction that Concha Arcae is staggered, and in embodiment, preferred cross interlocks.
This kind of overlaying structure has broken traditional one direction corrugated sheet stacking, the mode adopting two layers of Concha Arcae central layer square crossing is overlapped, this stacked system can bear the lateral pressure of all angles, traditional Concha Arcae core plate structure is only small for the ability to bear being parallel to the lateral pressure of Concha Arcae groove, only the lateral pressure that there is certain angle with valley of corrugation is had certain ability to bear.
S15: after the sandwich corrugated sheet pressurization do not welded is fixed, put into soldering oven, contact surface is carried out metallurgical binding.
Soldering oven is vacuum drying oven or atmosphere furnace, and brazing temperature is 450-650 degree, respectively the contact surface of panel with central layer, central layer and central layer is carried out metallurgical binding.
S16: obtain metal corrugated sandwich boards after cooling release;
The thickness of metal corrugated sandwich boards is 5��150mm, and metal corrugated sandwich boards can carry out splicing and adnexa welding.
After tested, the hot strength of Concha Arcae sandwich boards prepared by the present invention is about 10Mpa, and compressive strength is about 60Mpa, and peel strength is about 260N mm/mm, high temperature resistant 600 DEG C, and the life-span was up to 20 years.
