Described entrance tongue board is divided into A, B, three stepped structures of C with the tongue board body, wherein,
A section length: L A=(S A-S B)/sin α; Bending height S AFor=8*T; Thickness H A=0.05L A
B section length: L B=(S B-S C)/sin β; Bending height S B=S A* 15%; Thickness H B=0.024L B
C section length: L C=0.628 (L B+ L A); Bending height S C=T*1.2/2; H C=0.034L C

β is that the maximum in B district is lifted angle;
T is a sheet metal thickness.
Described entrance tongue board preferred size is:
The length L in A district ABe 818-1222mm, thickness H ABe 45-55mm;
The length 1910-3070mm in B district, thickness 50-70mm;
C zone length 1713-2695mm, thickness 60-100mm;
α=8°~12°;β=0.28°~0.45°。
Described entrance tongue board optimum size is:
The length 1000mm in A district, thickness 50mm;
The length 2500mm in B district, thickness 60mm;
The length 2200mm in C district, thickness 75mm; α=8 °; β=0.28 °.
As Fig. 6, shown in Figure 7, the inlet region of double-steel belt pressing machine can be divided into A, B, three districts of C, the A district is an exhaust gas region, effect is that the air in the slab 1 is discharged gradually, scope is Zi before the press cylinder that enters the mouth, according to the thickness of slab, adjust the deflection in A district by the size of adjusting power F, slab is steadily imported press; The B district is the transition pressor areas, can compress slab to the slab pressurization according to the compression speed of technological requirement; The C district is fixing higher-pressure region, covers whole higher-pressure regions of press, and mainly acting on is that the pressure of hydraulic cylinder is passed to slab by roller bar and steel band.
Only to have an A district different with the B district with existing entrance tongue board, and the C district is peculiar zone of the present invention.The internal production of entrance tongue board the heating oilhole of certain diameter and spacing be the entrance tongue board heating as the passage of heating carrier.
Entrance tongue board adopts stepped structure fabrication, is made into different length and thickness according to A, B, three zones of C.
According to the technological requirement of Wood-based Panel Production, the maximum in entrance tongue board A district is lifted angle [alpha]=8 °-12 °.If angle [alpha] is excessive, when entering press, slab, reduces the surface quality of sheet material because exhaust velocity is too fast, and the gas of discharge can damage slab, if angle [alpha] is too little, can cause pressing time too late.The concrete numerical value that maximum is lifted angle [alpha] is by the raw material decision of Wood-based Panel Production, and when using the coniferous forest raw material, exhaust performance is better, at this moment can select bigger exhaust angle [alpha]=12 °; If use the broad-leaf forest raw material, the exhaust performance of the fiber that this raw material are produced is relatively poor, at this moment will select to use less exhaust angle [alpha]=8 °.Most of areas are that coniferous forest and broad-leaf forest mix use, and the concrete numerical value of angle will use local raw-material proportioning actual conditions determine according to equipment.Equally according to the technological requirement of Wood-based Panel Production, it is β=0.28 °-0.45 ° that the maximum of entrance tongue board 7B district pressing plate is lifted angle.
According to the technological requirement of Wood-based Panel Production, the needs of fiber in the A district are compressed to 15% of slab thickness, need be compressed to 1.2 times of finished product sheet metal thickness in the B district.
According to the fertile maximum ga(u)ge of this kind double-steel belt pressing machine is that T=25mm is an example, entrance tongue board bending height: S A=8*T=200mm, S B=S A* 15%=30mm, S C=T*1.2/2=15mm.By the requirement of the technological parameter of above press, calculate entrance tongue board A section length: L A=(S A-S B)/sin α=(200-30)/sin (8 °-12 °), L ALength range be: 818-1222mm.
L in like manner B=(S B-S C)/sin β; β=(0.28 °-0.45 °) calculates L BLength range be: 1910-3070mm.
L CBe the length of higher-pressure region, according to the ratio difference of Wood-based Panel Production raw material ratio, L CScope be 1713-2695mm.
The conduction oil passage owing to laterally arranged in the entrance tongue board, stressed back deformation state complexity, the FEM model of setting up entrance tongue board according to the above length dimension data and the hydraulic jack pressurization situation of entrance tongue board, pass through finite element analysis computation, try to achieve each regional thickness range of entrance tongue board, H A=45-55mm, H B=50-70mm, H C=60-100mm.Adopt the round-corner transition of certain distance or the mode transition of employing gradient thickness between the zone of different-thickness.
As shown in Figure 7, can be adjusted into different angle work to entrance tongue board according to the difference of slab thickness during work.When entrance tongue board was done the distortion adjustment, because a-quadrant thickness is the thinnest, under the situation of same distortion, the suffered bending stress of entrance tongue board lower surface of the present invention had only the 30%-40% of existing entrance tongue board, can be improving 2 ~ 4 times the service life of tongue board.
The B area thickness is big slightly.Because the A district is flexible higher, can produce enough distortion and allow slab import press, so during work B only need to finish less distortion in district just passable, the while can be born bigger contact stress.In the present known structure, the arrangement pitch of hydraulic cylinder is all greater than 500mm, in structure of the present invention, reduced the spacing of B zone hydraulic cylinder, its spacing changes 400mm-450mm into, the result of finite element analysis shows that under the identical situation of average pressure, the suffered maximum bearing stress of tongue board has had obvious reduction than existing structure after the adjustment spacing.
The thickness maximum in C zone because the distortion in a-quadrant and B zone can have been satisfied the needs of inlet angle fully, so the C zone does not need flexural deformation substantially, has only the bearing stress that contacts with the roller bar when work.Because the C zone is the thickest, the distortion that produces behind the pressurized is less, and for avoiding waste of material, big slightly in C zone hydraulic cylinder gap ratio B district, maximum bearing stress still is controlled within the reasonable range.
In present known structure, as shown in figure 10, the entrance tongue board of existing structure has only the scope in A district and B district, length is about about 3.5 meters, first heating platen length after the inlet is about about 8 meters, first heating platen is higher-pressure regions for nearly 2.2 meters in the position that joins with entrance tongue board, and remainder is a low-pressure area.As everyone knows, metal is under the effect of bearing the circulation high pressure stress for a long time, and its surface will inevitably produce fatigue rupture.Entrance tongue board in the existing structure is because bearing the bigger bending stress effect and the effect of contact stress simultaneously damages easily, and first heating platen after the inlet also damages easily because bear very high bearing stress simultaneously.Because the length of heating platen is than length and in the inside of press, difficulty and the cost changed are all very high.
As shown in Figure 6, the present invention is the length dimension of entrance tongue board about 5.7 meters by present known about 3.5 meters lengthenings, covered the higher-pressure region of double-steel belt pressing machine, the region limits of stressed maximum within tongue board, after fatigue damage appears in the metal surface that works long hours, only need to change entrance tongue board and just can.Changed the situation that needs to change entrance tongue board and higher-pressure region heating platen in the existing known structure, reduced cost and reduced the difficulty of changing simultaneously.
Good effect of the present invention is: the one, and adopt the travelling frame structure to replace stationary frame structure to make cylinder plunger not produce relative slip down in working order with backing plate, avoided causing greatly because of sliding-frictional resistance phenomenons such as frame plate distortion and hydraulic cylinder sealing rapid wear in the past.The 2nd, by changing the physical dimension of entrance tongue board, make the stressed distribution of entrance tongue board more reasonable, the service life of having improved entrance tongue board greatly.
