[0002] There are two main ways to make bent wood parts on furniture: bending solid wood and bending and pressing multiple layers of veneer. Bending solid wood has restrictions on wood species, and requires wood steaming, wood drying and other technologies, and has high requirements for equipment and environment. The veneer bending technology has the following problems: 1. Each component needs an independent bent wood mold; 2. The cost of bent wood molds is high, and dozens of layers of boards need to be combined together to make them; 3. The commonality of bent wood molds is not strong, which has great restrictions on design, and the number of finished products used for a single product is high; 4. The pressing of bent wood molds and the production process of parts are complex and have many steps, and the cycle is long. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides a method for processing bent wood panels for furniture, which can save labor and bent wood mold material costs. The bending angles of bent wood parts are easily controlled and they will not rebound or deform after bending, thereby greatly improving the quality.

[0004] The present invention is implemented as follows: a method for processing a bent wood panel for furniture, wherein the bent wood panel comprises a panel body, the surface of the panel body is provided with a surface veneer, a placement space is provided at a bending position of the panel body, the placement space is formed by bending the cut edge, and an inner side pad matching the bending structure is provided in the placement space;

[0005] The processing method comprises the following steps:

[0006] S1. According to the design drawings of the components, the specific position and curvature of the inner pads are decomposed;

[0007] S2, processing the corresponding inner side pad parts;

[0008] S3, determining a bending position on the panel body and performing cutting at the position;

[0009] S4, sanding the cut edges;

[0010] S5, moistening the cut edges after sanding in the panel body;

[0011] S6. After the cut is completely penetrated, bend the panel body to the required position;

[0012] S7. Apply glue to the contact surfaces of the inner pad and the cut edge respectively, and put the inner pad into the cut edge of the plate at the bend;

[0013] S8. Apply pressure to fix.

[0014] Furthermore, the step S1 is specifically as follows: according to the design drawings of the components, in auxiliary software such as CAD, the cross-section of the bent wood panel is drawn in detail, the surface veneer is drawn according to the thickness of the veneer, and according to the arc radius of the bent wood panel, the position and shape of the inner pad is obtained by cutting from the center of the arc.

[0015] Furthermore, the step S2 specifically includes: using a four-sided planer to process the inner side wood member corresponding to the bending curvature.

[0016] Furthermore, the step S3 is specifically as follows: in auxiliary software such as CAD, the curved wood panel is unfolded from a curve to a plane, and the spatial dimensions generated by the inner pads are the cutting dimensions on the unfolded flat panel body; at this time, the required inner pad space is processed at the corresponding position on the flat panel body, and the cutting is performed using a saw blade or milling equipment.

[0017] Furthermore, the step S6 is specifically as follows: when the moisture content of the surface veneer at the cut position reaches more than 50%, bending is performed, one end of the panel body is lifted, and then the panel body is evenly heated using a heating device until the panel body is bent to the required position.

[0018] Furthermore, the cutout size corresponds to the arc length size.

[0019] Furthermore, the thickness of the inner pad is 1.5 mm thinner than the thickness of the panel body.

[0020] The advantages and technical effects of the present invention are as follows: due to the adoption of the above technical scheme, the use of this process to produce bent wood parts not only saves labor and material costs, but also saves product production time; the bending angles of bent wood parts are easy to control and will not rebound or deform after bending, which greatly improves the quality.

[0035] S3, determining a bending position on the panel body 1, and making a cut 4 at the position, wherein the size of the cut 4 corresponds to the length of the arc;

[0036] Specifically, in auxiliary software such as CAD, the curved wood panel is unfolded from a curve to a plane, and the spatial dimension generated by the inner pad 2 is the dimension of the cutout 4 on the unfolded flat panel body 1; at this time, the required space for the inner pad 2 is processed at the corresponding position on the flat panel body 1, and the cutout 4 is processed using a saw blade or milling equipment.

[0037] S4, sanding the cut 4 to ensure it is smooth;

[0040] Specifically, wait for the cut 4 to be penetrated by water. When the moisture content of the surface veneer 3 at the cut 4 reaches more than 50%, bend it, lift one end of the panel body 1, and then use a heating device to evenly heat the panel body 1 until the panel body 1 is bent to the required position.

[0041] S7, apply glue to the contact surfaces of the inner pad 2 and the cutout 4 respectively, and put the inner pad into the cutout 4 at the bend of the plate;

[0044] As shown in the table below, before the improvement, the required working hours were 4 hours for milling the bent wood mold, 4 hours for assembly, and 1 hour for hot pressing the track; after the improvement, the required working hours were 0.5 hours for milling the bent wood mold, 0.5 hours for assembly, and 0.3 hours for hot pressing the track. Therefore, the improved solution not only reduced personnel costs and bent wood mold material costs, but also significantly shortened the working hours.
