The setting of the front baffle 113 is beneficial to fixing the plate to be pressurized.

[0052] The present invention also provides a method for manufacturing a circular arc plate, using the auxiliary pressurizing device 10, the manufacturing method comprises the following steps:

[0053] a. Determine the arc angle R of the required arc plate 40;

[0054] b. Plate processing: Use an engraving machine to mill out a wide bending groove 21 with an arc angle of R at the position where the plate needs to be bent, so as to obtain an arc-shaped plate 20, such as Figure 6-7 As shown;

[0055] c. Wood block processing: According to the arc angle R and the depth of the bending wide groove 21, a plurality of milling grooves 31 are milled out of the flat wood block by a carving machine to obtain a bent wood block 30, such as Figure 8-9 As shown, the width of the bending wood block 30 is 1 mm smaller than the width of the bending wide groove 21, so that the bending wood block 30 can be filled in the bending wide groove 21;

[0056] d. Fixing the arc plate 20: Fix the arc plate 20 on the auxiliary pressure device 10, wherein the bending position of the arc plate 20 fits on the arc surface 1111, the vertical part 22 of the arc plate 20 is against the vertical side surface 1110 of the supporting vertical plate 111, and the horizontal part 23 of the arc plate 20 is supported on the horizontal surface 1112, as shown in FIG. Fig.10 As shown;

[0057] e. Gluing and filling the bending wood block 30: first, fully coat the inside of the bending wide groove 21 with curing glue, then place the bending wood block 30 into the bending wide groove 21, and coat the curing glue on the surface of the bending wood block 30 and the milling groove 31;

[0058] f. Pressurization: Rotate the pressurizing screw 123, which is pressed vertically against the top of the vertical portion 22 of the plate, and apply a preset range of pressure to the curved plate 20 through the pressurizing screw 123, such as Fig.10 As shown;

[0059] g. Keep the pressure fixed at room temperature until the glue hardens, and the arc plate 40 is completed. Fig.11 shown.

[0060] In this embodiment, a wide bending groove 21 with an arc angle of R is milled out at the plate-shaped position to be bent by an engraving machine to obtain an arc-shaped plate 20, and then the arc-shaped plate 20 is fixed on the auxiliary pressure device 10, and the arc-shaped plate 20 is attached to the supporting bonding surface, and then curing glue is applied in the wide bending groove 21, and the bending wood block 30 is filled in the wide bending groove 21. The surface of the bending wood block 30 and the milling groove 31 are coated with curing glue, and then the pressure mechanism 12 is used to apply axial pressure to the arc-shaped plate 20, and the pressure is kept fixed. It only needs to be left at room temperature for 2 hours, and after the curing glue hardens, the arc plate 40 is formed. This manufacturing method applies continuous pressure to the arc-shaped plate 20 by the pressure mechanism 12, without the need for long-term hot pressing, and effectively solves the risk of rebound fracture of the existing arc-shaped plate 40 after hot pressing.

[0061] In addition, the present invention fills the processed bent wood block 30 into the bent wide groove 21, and then bonds the two together through a curing glue, and then presses them together through an auxiliary pressurizing device 10 to achieve the overall production of the arc plate 40. The production cost is low, and the produced arc plate 40 is not prone to cracking. The bent wood block 30 is used to strengthen the bending part of the arc plate 40 to ensure the overall structural strength.

[0062] As a preferred embodiment, the thickness of the curved plate 20 at the wide bending groove 21 is 0.8-1.4 mm.

[0063] As a preferred embodiment, in step e, there is a fitting gap between the bent wooden block 30 and the bent wide groove 21, and when the fitting gap is ≤1 mm, the two are considered to be in a tightly bonded state.

[0064] Please refer to Fig.12 As shown in Table 1, since the bending wood block 30 and the bending wide groove 21 are bonded together by curing glue, there will be a bonding gap between the two, and the bonding gap is related to the amount of glue filled. The test shows that when the amount of glue inside the bending wide groove 21 is less than 70g and the amount of glue on the bending wood block 30 is less than 500g, the bonding between the bending wide groove 21 and the bending wood block 30 is insufficient, resulting in a poor bonding effect; when the amount of glue inside the bending wide groove 21 is greater than 70g, the amount of glue on the bending wood block 30 is greater than 500g. When the amount of glue is greater than 500g, glue overflow occurs at the bonding point between the wide bending groove 21 and the bending wooden block 30, which will affect the subsequent curing effect; when the amount of glue inside the wide bending groove 21 is 70g and the amount of glue on the bending wooden block 30 is 500g, the wide bending groove 21 and the bending wooden block 30 are fitted tightly; it can be seen that when the ratio of the amount of glue inside the wide bending groove 21 to the amount of glue on the bending wooden block 30 is 70-500, the fitting gap is ≤1mm, and the two are in a tightly bonded state at this time.

[0065] As a preferred embodiment, in step f, the axial pressure applied by the pressure screw 123 is 220-320N, and the bending part of the arc-shaped plate 20 and the bent wood block 30 both achieve a close adhesion effect.

[0066] In this embodiment, since the pressure is applied to the arc-shaped plate 20 by the pressure screw 123, the pressure determines the fitting effect between the bending part of the arc-shaped plate 20 and the bent wood block 30, see Fig.13 Table 2 shows the gap distance between the bending part of the arc plate 20 and the bending wood block 30 when the pressure screw 123 applies different axial pressures: when the axial pressure applied by the pressure mechanism 12 is less than 220N, the pressure is insufficient, resulting in the situation that the bending part of the arc plate 20 and the bending wood block 30 cannot be tightly bonded, that is, there will be a large gap between the bending part of the arc plate 20 and the bending wood block 30. The test shows that when the gap distance is greater than 1mm, the tight bonding effect is not achieved; when the axial pressure applied by the pressure mechanism 12 is greater than 320N, the pressure is too large, resulting in damage to the bending part of the arc plate 20 and the bending wood block 30; when the axial pressure applied by the pressure mechanism 12 is 220-320N, the bending part of the arc plate 20 and the bending wood block 30 are tightly bonded, and the gap distance is ≤1mm. It can be seen that the axial pressure applied by the pressurizing screw 123 cannot be too large or too small. Tests have shown that when the axial pressure applied by the pressurizing screw 123 is 220-320N, the bending part of the arc-shaped plate 20 and the bent wood block 30 both achieve a close adhesion effect, that is, the gap distance S≤1mm.

[0067] As a preferred embodiment, the board is made of triamine paper layer and medium fiber layer pressed into triamine medium fiber board. This embodiment uses triamine medium fiber board to make the arc board 40, which has the advantages of environmental protection, wear resistance, high temperature resistance, corrosion resistance, waterproof, simplicity and convenience.
