Description
Technical Field
[0001] This utility model relates to the field of solid wood bending assistance technology, and in particular to a device for solid wood bending assistance. Background Technology
[0002] Solid wood bending is a key process in furniture manufacturing, musical instrument production, and the shaping of wooden handicrafts. In traditional solid wood bending techniques, due to the natural rigidity and brittleness of wood fibers, the wood needs to be pre-treated to improve its plastic deformation capacity, thereby achieving complex curvature shapes.
[0003] Currently, the mainstream pretreatment method is mainly chemical treatment, which softens the wood by impregnating the surface or interior of it with chemical softeners such as ammonia and urea, thereby destroying the lignin structure. However, chemical residues can alter the natural color and texture of the wood, reducing the aesthetics and environmental performance of the finished product. Secondly, the waste treatment liquid contains a large number of harmful substances, posing a risk of soil and water pollution, which contradicts the concept of green manufacturing. Furthermore, chemical treatment processes require supporting wastewater treatment systems, which puts enormous pressure on companies' environmental protection and cost control. Utility Model Content
[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0005] Specifically, the technical problem to be solved by this utility model is to provide an auxiliary device for bending solid wood in order to solve the technical problem of environmental damage caused by current chemical treatment processes.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0007] A device for assisting in bending solid wood includes a heating chamber. Inside the heating chamber is a set of rotating clamping assemblies, with adjacent rotating clamping assemblies in a meshing transmission state. Drive assemblies are installed on both sides of the top of the heating chamber, with their drive ends located inside the heating chamber, driving the outermost rotating clamping assembly to rotate. The heating chamber has two feed holes, the number of which matches the number of rotating clamping assemblies.
[0008] The rotary clamping assembly includes two ring disks, and mounting tubes are coaxially welded to the opposite end faces of the two ring disks. A bidirectional clamping structure is installed on the end face of the ring disk away from the mounting tube. A clamping column is fixed in the middle of the opposite face of the two clamping ends of the bidirectional clamping structure, and the opposite ends of the two clamping columns are provided with arc-shaped surfaces.
[0009] As an improved technical solution, an air outlet chamber is installed inside the heating chamber and directly below each rotating clamping assembly, and the top of the air outlet chamber is provided with multiple air outlet holes.
[0010] As an improved technical solution, the drive assembly includes a rod frame fixed to the top of the rod frame, an electric telescopic rod is mounted on the top surface of the rod frame, a long rod is fixedly connected to the movable end of the electric telescopic rod, a connecting block is fixedly connected to the end of the long rod away from the electric telescopic rod, a straight rack is fixedly mounted on the side of the connecting block near the rotating clamping assembly, and a circular rack that meshes with the straight rack is mounted on the peripheral surface of the ring disc.
[0011] As an improved technical solution, the end of the mounting tube away from the annular disc is rotatably mounted on the inner wall of the heating chamber via a bearing, and the mounting tube and the feed hole are coaxially arranged.
[0012] As an improved technical solution, the bidirectional clamping structure includes two electrically operated telescopic rods installed on both sides of the ring disc near the end face of the mounting tube. The movable end of the electrically operated telescopic rod is fixedly connected to a connecting column. A movable block is welded to the end face of the connecting column away from the electrically operated telescopic rod. Push-pull strips are hinged to both ends of the ring disc near the connecting column. A linkage strip is hinged between the ends of the push-pull strips on both sides away from the movable block. The clamping column is fixed in the middle of the linkage strip. At the same time, the linkage strip is slidably installed on the ring disc.
[0013] As an improved technical solution, a slider is fixed at the middle of the end face of the linkage bar near the ring disk, and guide rails are installed at the upper and lower positions of the end face of the ring disk near the linkage bar, and the slider is slidably mounted on the guide rails.
[0014] As an improved technical solution, a set of hinge blocks 1 are installed at both ends of the movable block near the connecting column. A hinge column 1 is rotatably installed between two hinge blocks 1 in the same set, and the end of the push-pull bar near the movable block is rotatably installed on the hinge column 1. A set of hinge blocks 2 are installed at both ends of the linkage bar. A hinge column 2 is rotatably installed between two hinge blocks 2 in the same set, and the end of the push-pull bar near the linkage bar is rotatably installed on the hinge column 2.
[0015] After adopting the above technical solution, the beneficial effects of this utility model are:
[0016] 1. This utility model shortens the distance between the two clamping posts and clamps the solid wood between the two clamping posts, releasing the clamping and fixing of the solid wood. The solid wood is clamped from both ends, making the clamping more secure and stable. At the same time, the distance between the two clamping posts is adjustable by the extension and retraction of the electric telescopic rod, which can be used to adapt to solid wood of different sizes within a certain range, improving adaptability and practicality.
[0017] 2. In this utility model, the meshing transmission between the rack and the ring disc drives the ring disc to rotate. The solid wood is clamped on the ring disc, and the rotation of the ring disc also drives the solid wood to rotate. This allows the solid wood to be heated by steam while also rotating 360 degrees back and forth, expanding the contact area between the solid wood and the steam. This ensures that the solid wood is in contact with the steam at all 360 degrees, improving the comprehensiveness and uniformity of steam heating of the solid wood.
[0018] 3. This utility model allows solid wood to be bent using only water vapor, avoiding the environmental impact of chemical treatments. It is environmentally friendly and pollution-free. At the same time, the bending process does not damage the continuous fiber structure of the wood, resulting in a finished product with high strength, excellent compressive strength and toughness, unique aesthetics, and the preservation of the wood's integrity. It is widely applicable to woods with good toughness, such as oak and beech, and can achieve complex curved shapes, making it suitable for furniture and decorative design with strong applicability.

[0030] like Figures 1 to 4 As shown in the figure, this embodiment provides a solid wood bending auxiliary device. This solid wood bending auxiliary device includes a heating chamber 1. A set of rotating clamping components 3 is installed inside the heating chamber 1, and two adjacent rotating clamping components 3 are in a meshing transmission state. A drive component 2 is installed on both sides of the top of the heating chamber 1, and the drive end of the drive component 2 is located inside the heating chamber 1, and drives the outermost rotating clamping component 3 to rotate. Both sides of the heating chamber 1 have feeding holes 11 with the same number as the rotating clamping components 3.
[0031] The rotary clamping assembly 3 includes two ring disks 31. The opposite end faces of the two ring disks 31 are coaxially welded with mounting tubes 33. A bidirectional clamping structure is installed on the end face of the ring disk 31 away from the mounting tubes 33. A clamping post 38 is fixed in the middle of the opposite face of the two clamping ends of the bidirectional clamping structure, and the opposite ends of the two clamping posts 38 are provided with arc-shaped surfaces.
[0032] Solid wood can be bent using traditional bending techniques that require only steam, avoiding the environmental impact of chemical treatments. This process is environmentally friendly and pollution-free. At the same time, the bending process does not damage the continuous fiber structure of the wood, resulting in a finished product with high strength, excellent compressive strength and toughness, unique aesthetics, and the preservation of the wood's integrity. It is widely used for woods with good toughness, such as oak and beech, and can achieve complex curved shapes, making it suitable for furniture and decorative design and highly versatile.
[0033] like Figure 1 As shown, in this embodiment, an exhaust chamber 4 is installed inside the heating chamber 1 and directly below each rotating clamping assembly 3. The multiple exhaust chambers 4 are connected in parallel by pipes and are internally connected. The exhaust port of the steam generator is connected to the pipe inlet. Multiple exhaust holes 5 are opened on the top of the exhaust chamber 4.
[0034] like Figures 1 to 2 As shown in the figure, in this embodiment, the drive assembly 2 includes a rod frame 21 fixed to the top of the rod frame 21. An electric telescopic rod 22 is installed on the top surface of the rod frame 21, and the movable end of the electric telescopic rod 22 is located inside the heating chamber 1. A long rod 23 is fixedly connected to the movable end of the electric telescopic rod 22. A connecting block 24 is fixedly connected to the end of the long rod 23 away from the electric telescopic rod 22. A straight rack 25 is fixed to the side of the connecting block 24 near the rotating clamping assembly 3. A circular ring that meshes with the straight rack 25 is installed on the peripheral surface of the ring disk 31. The rack 37 drives the electric telescopic rod 22 to reciprocate and move the rack 25 up and down. Under the meshing transmission action of the rack 25 and the ring disk 31, the ring disk 31 will be driven to rotate. The solid wood is clamped on the ring disk 31, and when the ring disk 31 rotates, it will also drive the solid wood to rotate. This allows the solid wood to be heated by steam while also reciprocating 360 degrees, expanding the contact area between the solid wood and the steam, so that the solid wood is in contact with the steam at 360 degrees, improving the comprehensiveness and uniformity of steam heating of the solid wood.
[0035] like Figures 1 to 4 As shown in the figure, in this embodiment, the end of the mounting tube 33 away from the ring disk 31 is rotatably mounted on the inner wall of the heating chamber 1 through a bearing, and the mounting tube 33 and the feed hole 11 are coaxially arranged.
[0036] like Figures 3 to 4As shown in the figure, in this embodiment, the bidirectional clamping structure includes two electrically operated telescopic rods 32 mounted on both sides of the end face of the ring disc 31 near the mounting tube 33. The movable end of the electrically operated telescopic rod 32 is located on the end face of the ring disc 31 away from the mounting tube 33. A connecting post 310 is fixedly connected to the movable end of the electrically operated telescopic rod 32. A movable block 39 is welded to the end face of the connecting post 310 away from the electrically operated telescopic rod 32. Push-pull strips 311 are hinged to both ends of the ring disc 311 near the connecting post 310. A linkage strip 34 is hinged between the ends of the push-pull strips 311 away from the movable block 39 on both sides. The clamping post 38 is fixed to the linkage strip 34. In the middle of 4, the linkage bar 34 is slidably installed on the ring plate 31. Under the linkage action of the push-pull bar 311, the two linkage bars 34 move towards the middle at the same time, shortening the distance between the two clamping posts 38 and clamping the solid wood between the two clamping posts 38. Conversely, the electric telescopic rod 32 shortens and widens the distance between the two clamping posts 38, releasing the clamping and fixing of the solid wood, and clamping the solid wood from both ends, making the clamping more secure and stable. At the same time, the distance between the two clamping posts 38 is adjustable by the extension and retraction of the electric telescopic rod 32, which can be used to adapt to different sizes of solid wood within a certain range, improving adaptability and practicality.
[0037] like Figure 4 As shown, in this embodiment, a slider 35 is fixed at the middle of the end face of the linkage bar 34 near the ring disk 31, and guide rails 36 are installed at the upper and lower positions of the end face of the ring disk 31 near the linkage bar 34, and the slider 35 is slidably installed on the guide rails 36.
[0038] like Figure 4 As shown, in this embodiment, a set of hinge blocks 1 are installed at both ends of the movable block 39 near the connecting column 310. A hinge column 1 is rotatably installed between two hinge blocks 1 in the same set, and the end of the push-pull bar 311 near the movable block 39 is rotatably installed on the hinge column 1. A set of hinge blocks 2 are installed at both ends of the linkage bar 34. A hinge column 2 is rotatably installed between two hinge blocks 2 in the same set, and the end of the push-pull bar 311 near the linkage bar 34 is rotatably installed on the hinge column 2.
[0039] In use, solid wood enters the clamping cavity of the rotary clamping assembly 3 through the feed hole 11. The clamping process of the two-way clamping structure for solid wood is as follows:
[0040] When the solid wood is located between the inner holes of the two ring discs 31, the electric telescopic rod 32 extends and drives the movable block 39 to move away from the electric telescopic rod 32. Under the linkage of the push-pull bar 311, the two linkage bars 34 move towards the center at the same time, shortening the distance between the two clamping posts 38 and clamping the solid wood between the two clamping posts 38. Conversely, the electric telescopic rod 32 shortens and widens the distance between the two clamping posts 38, releasing the clamping and fixing of the solid wood.
[0041] Steam generated by the steam generator is continuously fed into the air chamber 4. The steam is sprayed out through the air outlet 5 onto the solid wood, thereby heating the solid wood. In the high temperature and high humidity environment, water vapor penetrates into the wood, softening the wood cellulose. At this time, the bonding force between the wood fibers weakens, allowing the wood to deform without cracking. After bending, the wood is dried and cured, the moisture between the fibers evaporates, the bonding force is restored, and the shape is fixed.
[0042] While heating, the electric telescopic rod 22 drives the rack 25 to move reciprocally up and down. Under the meshing transmission action of the rack 25 and the ring disk 31, the ring disk 31 will be driven to rotate. The solid wood is clamped on the ring disk 31, so when the ring disk 31 rotates, it will also drive the solid wood to rotate. This allows the solid wood to be heated by steam while also rotating 360 degrees reciprocating, expanding the contact area between the solid wood and the steam.
[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
