Description

Technical Field

[0001] The utility model relates to the technical field of solid wood furniture production, and more specifically to a plate bending device for solid wood furniture production. Background Art

[0002] Solid wood furniture is furniture made of solid wood. The materials used in its production are all pure natural wood. There is no artificial synthetic board material. Because the material of solid wood furniture is pure natural and pollution-free, it is deeply loved by consumers. The diverse shapes of solid wood furniture require the assistance of plate bending devices.

[0003] Chinese patent application number CN202020988281.7 discloses a plate punching device for wooden furniture production, including a base frame, a frame fixed to the top of the base frame, a pressing plate fixed to the telescopic end of the hydraulic cylinder, blocks fixed to the left and right sides of the top of the base frame, and a measuring component provided inside the base frame. The plate punching device for wooden furniture production can achieve one-way locking when the vertical rod sinks through the cooperation of the base frame, the frame, the hydraulic cylinder, the pressing plate, the block and the measuring component, and the vertical rod sinking length can be obtained by comparing the pointer with the scale, and then the bending degree of the plate can be measured, and its compressive strength can be determined by its bending degree, and then defective products can be screened out to ensure the quality of the finished furniture. The position of the blocks on both sides can be adjusted through the clearance cooperation between the slider and the slide groove. At the same time, through the threaded connection between the screw and the support plate, and the setting of the hexagonal block, plates of different sizes and thicknesses can be tightly fixed, thereby improving the stamping stability;

[0004] The above technical solution can realize the tight fixation of plates of different sizes and thicknesses, thereby improving the stamping stability. However, the shapes of solid wood furniture in life are various, including the bending curvature of solid wood furniture plates. The existing bending device usually has a curvature mold roller. When bending the plate, in order to stabilize the bending process, the arc mold roller is usually fixed to the equipment by screws. To produce solid wood furniture with different curvatures, it is necessary to replace the corresponding arc mold roller. The back and forth disassembly and assembly of the screws during the mold replacement process not only affects the processing speed of the bending device on the plate, but also reduces the production efficiency of the solid wood furniture plate.

One end of the guide rod 8 is fixedly connected to the slider 5, and the other end of the guide rod 8 is fixedly connected to a ball head 10. A first spring 9 is elastically connected between the slider 5 and the fixed square column 7. A fixed disk 11 is fixedly installed on the end surface of the bending mold 3. A groove is provided on the surface of the fixed disk 11. A plug post 12 matching the plug post is movably connected inside the groove. A chamfer is provided at one end of the plug post 12. A second spring 13 is elastically connected between the plug post 12 and the inner wall of the bending mold 3. A plurality of bayonet holes 14 are provided on the side surface of the plug post 12. A locking mechanism for locking the bayonet hole 14 is provided inside the fixed disk 11. To produce solid wood furniture with different curvatures, there is no need to disassemble and assemble screws back and forth to replace the mold. Only the expansion radius of the arc plate 6 needs to be adjusted, which not only improves the processing speed of the bending device on the plate, but also improves the production efficiency of the solid wood furniture plate.

[0026] A groove is provided inside the fixed disk 11, and a locking mechanism is arranged inside the groove. The locking mechanism includes a fixed plate 15, which is fixedly connected to the inner wall of the groove.

[0030] The use steps of the utility model are as follows: when the board bending device for producing solid wood furniture is in use, when the bending curvature of the produced solid wood furniture board is different, the plug column 12 is manually pressed to move toward the inside of the fixed square column 7, and the surface of the plug column 12 is provided with a chamfer. During the movement of the plug column 12 in the fixed square column 7, the second spring 13 is squeezed, and one end of the plug column 12 squeezes the ball head 10, and the movement of the ball head 10 brings the guide rod 8 to move, thereby causing the slider 5 to bring the arc plate 6 to move toward the outside of the bending mold 3.

One end of the plug post 12 squeezes the ball head 10. The ball head 10 moves with the guide rod 8, thereby causing the slider 5 to move with the arc plate 6 toward the outside of the bending mold 3. At this time, the movement of the slider 5 stretches the first spring 9. According to the required bending curvature of the solid wood furniture board, the expansion radius of the arc plate 6 is adjusted. When the plug post 12 moves into the fixed square column 7, the surface of the plug post 12 is provided with a bayonet 14. When the expansion radius of the arc plate 6 is adjusted to the required bending curvature of the solid wood furniture board, the locking mechanism locks the bayonet 14. To produce solid wood furniture with different curvatures, there is no need to disassemble and assemble screws back and forth to replace the mold. Only the expansion radius of the arc plate 6 needs to be adjusted. This not only improves the processing speed of the bending device on the board, but also improves the production efficiency of the solid wood furniture board. Example 2
