Description

Technical Field

[0001] This invention relates to the field of furniture technology, and more specifically, to cabinet doors with a slanted opening guide structure. The invention may also be named a curved manufacturing table. Background Technology

[0002] Curved board processing is one of the core processes in the fields of whole-house customization, furniture manufacturing, and building decoration. Its technological evolution revolves around three core needs: efficiency improvement, precision control, and material adaptability. In traditional processes, steam bending or lamination methods are generally used. Steam bending involves softening the wood by steaming and then bending it under pressure, but it relies on manual operation, is inefficient, and is prone to rebound deformation due to insufficient drying and shaping. Lamination involves applying glue to thin boards, stacking them, and then molding them. The precision of the mold directly affects the uniformity of the curved surface, and the cost of changing molds is high, making it difficult to adapt to small-batch customization needs. The production of curved surfaces is closely related to the material of the board. In the process of processing small-radius curved surfaces, mainstream materials such as particleboard are prone to cracking or twisting due to uneven heating of the structure during bending. In traditional hot pressing processes, the color of the board surface becomes inconsistent due to temperature fluctuations, affecting the overall aesthetics.

[0003] Chinese Patent Application 1 (Application No.: 202411652306.5, Application Date: 2024.11.19) discloses a processing technology for an arc-shaped plate. The process involves placing an arc-shaped mold inside a sealed box, then placing the workpiece on the arc surface of the mold, and finally covering the box with a flexible sealing cover. A pressure difference is created between the inside and outside of the flexible sealing cover. Under this pressure difference, the flexible sealing cover deforms and compresses the workpiece to completely adhere it to the arc surface of the mold, maintaining this adherence for a preset time to shape an arc-shaped plate that matches the curvature of the arc surface. However, this process is time-consuming, inefficient, and inconvenient.

[0004] Chinese Patent Application 2 (Application No.: 202510347339.7, Application Date: 2025.03.24) discloses an arc plate manufacturing device and manufacturing process. The arc plate manufacturing device includes a frame, a device body set on the frame, a support platform fixed in the device body, a mold set above the support platform, a cover set on the top of the device body, and multiple radio frequency heaters set on the cover. It integrates radio frequency heaters and flexible molding film. After the plate is automatically aligned with the center by a positioning component, it is bent. The positioning component needs to be manually adjusted, which is difficult to operate. The replacement and maintenance of the flexible molding film is costly and requires downtime for maintenance, which affects the efficiency of continuous production. The dynamic adjustment of radio frequency heating parameters is difficult, resulting in poor practicality.

[0005] Therefore, it is necessary to provide a cabinet door with a slanted opening guide structure that is easy to operate, can effectively improve production efficiency, has low production cost, and is highly practical. Summary of the Invention

[0017] This invention provides an arc-shaped fabrication table, comprising: a table surface, a rotating mechanism, a mounting block, a fixing block, and a fitting block; the table surface is a rectangular plate with a U-shaped notch, with the notch located on one side of the table surface along the front-back direction, and a fixing block positioned opposite the edge of the notch on the left-right direction, the fixing block being a rectangular block, with an axle penetrating the fixing block inside; the two ends of the rotating mechanism are fitted to the fixing blocks, and the rotating mechanism is engaged with the notch; the rotating mechanism includes a pad plate, a flipping plate, a support plate disposed between the two flipping plates, a connecting plate, and an inclined plate; the mounting holes of the flipping plate are opposite to the mounting holes of the pad plate, and the mounting holes are connected to the fixing block via the axle, enabling rotation relative to the table surface. The connecting plate has an arc-shaped hole extending vertically through it at the end furthest from the support plate. This end connects to the center of the inclined plate. An elliptical cylindrical cavity extends vertically through the center of the inclined plate. In use, the elliptical cylindrical cavity communicates with the arc-shaped hole, serving as a handle for the manual rotation mechanism. A mounting block is placed on the tabletop. The mounting block includes side plates arranged opposite each other in the left-right direction, a back plate connecting the side plates, and a top plate. The side plates are irregularly shaped plates formed by connecting rectangular and trapezoidal plates. At least two interlocking plates are provided between opposing side plates, and a partition plate is provided between adjacent interlocking plates. Each interlocking plate includes a bent plate and a stepped plate connected sequentially in the left-right direction.

The heating element is encased in a steel pipe, which passes through mounting holes in the flip plate and pad furthest from the top. In use, the shaped panel is placed on the tabletop, the mounting block covers the shaped panel, and the side panels can... To prevent the molding board from wobbling on the table, the bonding surface of the bonding block is bonded to the inclined surface of the snap-fit ​​plate and the trapezoidal plate of the side plate. Along the vertical direction, the U-shaped groove of the molding board is located between the heating tube and the bonding block. After the heating tube is powered on, the operator holds the rotating mechanism to rotate it. The heating tube gradually moves closer to the U-shaped groove of the molding board. When the rotating mechanism rotates 90°, the heating tube pushes the U-shaped groove of the molding board to fully bond with the arc surface of the bonding block. Under the pressure between the mounting block and the rotating mechanism, the heating tube accelerates the deformation of the molding board, causing the U-shaped groove of the molding board to bend into an arc quickly by heat. This application has a simple structure and is easy to operate. It is suitable for making arcs of different curvatures and can effectively improve work efficiency.

Both ends of the support plate 5 are fixedly connected to the flip plate 4. In the up-down direction (z), the top of the support plate 5 is tangent to the bottom end of the mounting hole 31 along the extension line of the left-right direction (x), ensuring that the connection between the heating tube 8 and the rotating mechanism 100 is not affected, while simultaneously improving the stability of the rotating mechanism 100. In the up-down direction (z), a connecting plate 6 is located at the bottom end of the support plate 5. The connecting plate 6 is a rectangular plate extending in the left-right direction (x), with both ends fixedly connected to the flip plate 4. In the front-back direction (z), the connecting plate 6 is a rectangular plate extending in the left-right direction (x). In the direction y, the width of the connecting plate 6 is less than the width of the flip plate 4.

The irregular surface includes a stepped zigzag bent surface 281 that is perpendicular to the top surface of the L-shaped plate along the vertical direction z, a right-angled stepped vertical surface 283 that is perpendicular to the bottom surface of the L-shaped plate, and an inclined surface 282 that connects the bent surface 281 and the vertical surface 283. The inclination of the inclined surface 282 is the same as the inclination of the inclined surface 23 of the trapezoidal plate 222. The inclined surface 282 is attached to the bonding surface 31 of the bonding block 300. The corner of the zigzag of the bent surface 281 can be engaged with the connecting surface 32, further improving the connection stability between the mounting block 200 and the bonding block 300.

[0073] The bonding block 300 is embeddedly connected to the mounting block 200. The bonding block 300 includes a bonding surface 31 and an arc-shaped surface arranged opposite each other in the front-back direction y. The bonding surface 31 is a plane that is completely in contact with the inclined surface 23 and the inclined surface 282 of the trapezoidal plate 222. Along the extension direction of the bonding surface 31, both ends of the bonding surface 31 are provided with connecting surfaces 32, and the other end of the connecting surface 32 is connected to the arc-shaped surface.

[0074] It should be noted that the curvature of the curved surface of the bonding block 300 can be 45°, 60°, 90°, etc. This embodiment does not make specific limitations, only ensuring that the bonding surface 31 and the mounting block 200 can be bonded. The size of the connecting surface 32 can be adjusted. The rotatable angle of the rotating mechanism 100 is also 90°, which is beneficial for the rounding treatment of the U-shaped groove 91 of the molding plate 9.

[0075] The heating element 8 is wrapped with a steel pipe, which is inserted into the mounting hole 31 of the flip plate 4 and the pad plate 3 away from the top.

[0076] It should be noted that the heating tube 8 is wrapped with a steel pipe, which is inserted into the mounting hole 31 of the flip plate 4 and the pad plate 3 away from the top. The heating tube 8 wire extends out of the mounting hole 31 to conduct electricity.

[0077] It also includes a molding plate 9, which is a rectangular plate. Along the vertical direction z, the molding plate 9 is positioned between the countertop 1 and the mounting block 200. Along the horizontal direction x, the width of the molding plate 9 is less than or equal to the distance between the side plates 22 of the mounting block 200. The molding plate 9 includes a U-shaped groove 91 with its opening facing away from the countertop 1. Along the horizontal direction x, the width of the U-shaped groove 91 is greater than or equal to the width of the bonding plate along the vertical direction z.

[0078] It should be noted that the molding plate 9 is a material plate or workpiece that needs to be rounded. The position that needs to be rounded needs to be pre-milled into a U-shaped groove 91 of appropriate size to facilitate bending. The width of the U-shaped groove 91 is greater than or equal to the width of the bonding plate along the vertical z direction. This allows the U-shaped groove 91 to better fit with the curved surface of the bonding block 300 during the rounding process, thereby improving the rounding effect.

[0079] The tabletop 1, the rotating mechanism 100, the mounting block 200, and the fixing block 2 are all made of wood or MDF.

[0080] It should be noted that wood panels and MDF are relatively economical materials. Compared to metals or other synthetic materials, their procurement costs are generally lower. Wood panels and MDF are easy to cut, drill, and shape, making them ideal for manufacturing components requiring precise dimensions and shapes, such as countertops 1, mounting blocks 200, and fixing blocks 2. They also generate relatively little waste during processing, helping to reduce material waste. Wood panels and MDF are relatively lightweight while maintaining sufficient strength, making them easy to handle and install. For mechanisms requiring rotation or movement (such as rotating mechanism 100), the lighter weight reduces the required driving force and energy consumption. As a natural material, wood panels are renewable and do not produce harmful substances during use. Wood panels and MDF have good stability and durability, resisting wear and deformation during daily use.

[0081] As can be seen from the above embodiments, the arc-shaped fabrication table provided by the present invention achieves at least the following beneficial effects:

[0082] This invention provides an arc-shaped fabrication table, comprising: a table surface, a rotating mechanism, a mounting block, a fixing block, and a fitting block; the table surface is a rectangular plate with a U-shaped notch, with the notch located on one side of the table surface along the front-back direction, and a fixing block positioned opposite the edge of the notch on the left-right direction, the fixing block being a rectangular block, with an axle penetrating the fixing block inside; the two ends of the rotating mechanism are fitted to the fixing blocks, and the rotating mechanism is engaged with the notch; the rotating mechanism includes a pad plate, a flipping plate, a support plate disposed between the two flipping plates, a connecting plate, and an inclined plate; the mounting holes of the flipping plate are opposite to the mounting holes of the pad plate, and the mounting holes are connected to the fixing block via the axle, enabling rotation relative to the table surface. The connecting plate has an arc-shaped hole extending vertically through it at the end furthest from the support plate. This end connects to the center of the inclined plate. An elliptical cylindrical cavity extends vertically through the center of the inclined plate. In use, the elliptical cylindrical cavity communicates with the arc-shaped hole, serving as a handle for the manual rotation mechanism. A mounting block is placed on the tabletop. The mounting block includes side plates arranged opposite each other in the left-right direction, a back plate connecting the side plates, and a top plate. The side plates are irregularly shaped plates formed by connecting rectangular and trapezoidal plates. At least two interlocking plates are provided between opposing side plates, and a partition plate is provided between adjacent interlocking plates. Each interlocking plate includes a bent plate and a stepped plate connected sequentially in the left-right direction. The L-shaped panel has a flat surface on the side closest to the bend, and a shaped surface on the side furthest from the bend. This shaped surface includes a stepped, zigzag-shaped bend perpendicular to the top surface of the L-shaped panel, a right-angled stepped vertical surface perpendicular to the bottom surface of the L-shaped panel, and an inclined surface connecting the bend and vertical surfaces. The inclination of the inclined surface is the same as that of the inclined surface of the trapezoidal panel. The fitting block and mounting block are embedded together, with the fitting surface of the fitting block being a plane that completely fits the inclined surface and the inclined surface of the trapezoidal panel. The heating element is encased in a steel pipe, which passes through mounting holes in the flip plate and pad furthest from the top. In use, the shaped panel is placed on the tabletop, the mounting block covers the shaped panel, and the side panels can... To prevent the molding board from wobbling on the table, the bonding surface of the bonding block is bonded to the inclined surface of the snap-fit ​​plate and the trapezoidal plate of the side plate. Along the vertical direction, the U-shaped groove of the molding board is located between the heating tube and the bonding block. After the heating tube is powered on, the operator holds the rotating mechanism to rotate it. The heating tube gradually moves closer to the U-shaped groove of the molding board. When the rotating mechanism rotates 90°, the heating tube pushes the U-shaped groove of the molding board to fully bond with the arc surface of the bonding block. Under the pressure between the mounting block and the rotating mechanism, the heating tube accelerates the deformation of the molding board, causing the U-shaped groove of the molding board to bend rapidly into an arc. This device has a simple structure and is easy to operate. It is suitable for making arcs of different curvatures and can effectively improve work efficiency.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
