Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a wood bending and forming device. Background Technology

[0002] Wood is the lignified tissue formed by plants capable of secondary growth, such as trees and shrubs. Wood bending is a process that utilizes the plasticity of wood to bend straight wood into a specific curved shape through external force and physicochemical action. Wood bending equipment first needs to heat the wood, such as by boiling, steaming, or roasting, to soften the wood. This softens the hemicellulose and lignin in the wood cell walls, reduces the binding force between fibers, and allows the wood to bend under a smaller external force. Then, the softened wood is bent into the desired shape by compression.

[0003] CN218659648U discloses a wood bending and shaping device, including a worktable. The upper end of the worktable has a guide groove. A first guide pulley A, a second guide pulley A, and a third guide pulley A are sequentially arranged on one side of the guide groove. A drive motor is fixed to the bottom of the worktable with screws. Bending plates are installed on both sides of the inner wall of the guide groove using countersunk head screws. A first self-regulating heating cable and a second self-regulating heating cable with heating function are respectively installed inside the worktable and outside the guide groove. This novel wood bending and shaping device guides the transport of wood and heats the wood, effectively increasing the shaping speed and processing efficiency, thus achieving higher economic benefits and making it suitable for widespread use.

[0004] While the existing technology CN218659648U has many advantages in use, it still has the following problems: its heat preservation for wood is not perfect. After the wood is taken out of the heating box, its surface temperature will change due to contact with the forming device or the influence of the ambient temperature, which will affect the surface temperature of the wood and affect the softening effect of the wood. This will make the wood prone to breakage during the subsequent bending process, thus affecting the success rate of wood forming. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a wood bending and forming device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a wood bending and forming device, including a processing table, a limiting rod and a piston rod. An extrusion plate is provided on the outer side of the processing table. The upper outer wall of the processing table is screwed with equal and parallel limiting plates. The limiting rod is movably installed inside the limiting plate. An air supply head is screwed to the end of the limiting rod. The piston rod is movably installed inside the air supply head.

[0007] By adopting the above technical solution, the limiting rod can achieve multi-point shielding of the upper surface of the forming groove, preventing the wood from breaking and flying during bending, avoiding injury to workers, improving the safety of the wood bending process, and continuously spraying steam into the wood through the air inlet and outlet during the bending process to maintain the humidity and temperature of the wood, thus maintaining the temperature of the wood during the bending process, keeping the wood soft and flexible, reducing the probability of breakage during the bending process, and improving the success rate of wood forming.

[0008] Specifically, a forming groove is provided on one side of the outer wall of the upper end of the processing table, and the inner wall of the forming groove is designed with an arc shape. The shape of the extrusion plate is adapted to the shape of the forming groove.

[0009] By adopting the above technical solution, the workers place the wood in a flat area inside the forming groove, and through the cooperation of the arc forming groove and the extrusion plate, the wood can be precisely bent, ensuring the consistency of the wood forming.

[0010] Specifically, a hydraulic rod is screwed to one side of the lower outer wall of the processing table, and the end of the hydraulic rod is connected to the lower outer wall of the extrusion plate. Guide rods are screwed to both sides of the lower outer wall of the extrusion plate, and the guide rods are slidably installed on the lower outer wall of the processing table.

[0011] By adopting the above technical solution, the hydraulic rod can provide stable and controllable pressure, and the extension and retraction of the hydraulic rod can carry the extrusion plate to move synchronously, thereby enabling the extrusion plate to enter or move out of the forming groove. The guide rod can ensure the stability of the horizontal movement trajectory of the extrusion plate and guarantee the bending accuracy of the wood.

[0012] Specifically, a support spring is sleeved on the outer side of the limiting rod, and the two ends of the support spring are in contact with the outer wall of the limiting rod and the outer wall of the limiting plate, respectively.

[0013] By adopting the above technical solution, the support spring can maintain the position of the limiting rod. When the extrusion plate enters the forming groove, the top rod contacts and pushes the piston rod, causing the limiting rod to move inside the limiting plate. At this time, the support spring is compressed and stored, and the position of the air delivery head can be adjusted to ensure that the air delivery head in the middle can continuously spray air onto the bending apex of the wood, maintain the wood temperature, and reduce the probability of wood breakage.

[0014] Specifically, the gas delivery head has an exhaust channel inside, and a quick connector is threaded to one side of the inner wall of the exhaust channel. The quick connector is located at the upper end of the gas delivery head. The limiting rod has an exhaust hole inside, which corresponds to the position of the exhaust channel, and the exhaust direction of the exhaust hole is downward.

[0015] By adopting the above technical solution, the external steam generator gas supply pipe is connected to the exhaust channel through a quick connector, thereby enabling the wood inside the forming tank to be kept warm and moist through the exhaust channel and exhaust hole, ensuring the flexibility of the wood during the forming process.

[0016] Specifically, a return spring is sleeved on the outer side of the piston rod, and the two ends of the return spring are in contact with the outer wall of the piston rod and the outer wall of the gas delivery head, respectively. The piston rod is elastically connected to the gas delivery head through the return spring.

[0017] By adopting the above technical solution, the return spring maintains the position of the piston rod. When the worker places wood on a flat surface inside the forming tank, the piston plate can block the exhaust channel, preventing steam from harming the worker. As the extrusion plate moves into the forming tank, the push rod pushes the piston rod to move and compresses the return spring, allowing the steam to escape the blockage of the piston plate and flow inside the exhaust channel, thus achieving moisture retention and heat preservation during the wood bending process. After the extrusion plate retracts and resets, the return spring releases its elasticity to push the piston rod and piston plate back to their original positions, ensuring that the steam flows in a controlled manner inside the exhaust channel, thus ensuring the safety of the equipment.

[0018] Specifically, the piston rod end is threadedly connected to a piston plate, and both the piston plate and the exhaust channel are designed in a conical shape, with the piston plate located inside the exhaust channel.

[0019] By adopting the above technical solution, the cooperation between the conical piston plate and the exhaust channel can achieve linear airflow regulation. The exhaust can be precisely controlled by controlling the displacement of the piston rod, and the conical structure can achieve sealing under the action of the return spring.

[0020] Specifically, an arc-shaped plate is screwed to the outer wall of the upper end of the extrusion plate, and equal-spaced parallel push rods are welded to the outer wall of the arc-shaped plate. The push rods and the piston rod are on the same horizontal plane.

[0021] By adopting the above technical solution, when the extrusion plate moves horizontally, it can carry the arc plate and the top rod to move synchronously. When the extrusion plate initially contacts the wood, the top rod is in the state of pushing the piston rod, so that the piston plate is freed from the blockage of the exhaust channel, and the steam is discharged at this time.

[0022] The beneficial effects of this utility model are:

[0023] The wood bending and forming device described in this utility model can maintain the humidity and temperature of the wood, thereby maintaining the temperature during the bending process, preserving the softening and flexibility of the wood, reducing the probability of breakage during the bending process, and improving the success rate of wood forming.

[0024] The wood bending and forming device described in this utility model can achieve multi-point shielding of the upper surface of the forming groove, preventing the wood from breaking off and flying during the bending process, avoiding injury to workers, and improving the safety of the wood bending process.

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the wood bending and forming device of this utility model includes a processing table 1, a limiting rod 2 and a piston rod 3. An extrusion plate 14 is provided on the outer side of the processing table 1. The upper outer wall of the processing table 1 is screwed with equal and parallel limiting plates 12. The limiting rod 2 is movably installed inside the limiting plate 12. An air supply head 23 is screwed to the end of the limiting rod 2. The piston rod 3 is movably installed inside the air supply head 23.

[0034] When in use, the limiting rod 2 can block the upper surface of the forming groove 13 at multiple points, preventing the wood from breaking and flying during bending, thus avoiding injury to workers and improving safety during the bending process. It can also continuously spray steam onto the wood through the air supply head 23 and the exhaust port 22 during the bending process, maintaining the humidity and temperature of the wood. This maintains the temperature during the bending process, preserves the softening and flexibility of the wood, reduces the chance of breakage during bending, and improves the success rate of wood forming.

[0035] To control the bending shape, for example, such as Figure 1 As shown, a forming groove 13 is provided on one side of the upper outer wall of the processing table 1. The inner wall of the forming groove 13 adopts an arc shape design, and the shape of the extrusion plate 14 is adapted to the shape of the forming groove 13.

[0036] When in use, the staff places the wood in the flat area inside the forming groove 13, and the wood can be precisely bent by the cooperation between the arc forming groove 13 and the extrusion plate 14, ensuring the consistency of the wood forming.

[0037] To bend wood, for example, such as Figure 3 As shown, a hydraulic rod 11 is screwed to one side of the lower outer wall of the processing table 1. The end of the hydraulic rod 11 is connected to the lower outer wall of the extrusion plate 14. Guide rods 15 are screwed to both sides of the lower outer wall of the extrusion plate 14, and the guide rods 15 are slidably installed on the lower outer wall of the processing table 1.

[0038] In use, the hydraulic rod 11 can provide stable and controllable pressure, and the extension and retraction of the hydraulic rod 11 can carry the extrusion plate 14 to move synchronously, thereby enabling the extrusion plate 14 to enter or move out of the forming groove 13, while the guide rod 15 can ensure the stability of the horizontal movement trajectory of the extrusion plate 14 and ensure the bending accuracy of the wood.

[0039] To maintain the usage location, for example, such as Figure 2 As shown, a support spring 21 is sleeved on the outer side of the limiting rod 2, and the two ends of the support spring 21 are in contact with the outer wall of the limiting rod 2 and the outer wall of the limiting plate 12, respectively.

[0040] During use, the support spring 21 can maintain the position of the limiting rod 2. When the extrusion plate 14 enters the forming groove 13, the top rod 17 contacts and pushes the piston rod 3, causing the limiting rod 2 to move inside the limiting plate 12. At this time, the support spring 21 is compressed and stored, and the position of the air delivery head 23 can be adjusted. The air delivery head 23 located in the middle can continuously spray air onto the bending apex of the wood, maintain the wood temperature, and reduce the probability of wood breakage.

[0041] For steam flow, exemplarily, such as Figure 4 As shown, an exhaust channel 24 is provided inside the air supply head 23. A quick connector 25 is threaded to one side of the inner wall of the exhaust channel 24. The quick connector 25 is located at the upper end of the air supply head 23. An exhaust hole 22 is provided inside the limiting rod 2. The exhaust hole 22 is positioned corresponding to the exhaust channel 24, and the exhaust direction of the exhaust hole 22 is downward.

[0042] During use, the external steam generator's gas supply pipe is connected to the exhaust channel 24 via a quick connector 25, thereby enabling the wood inside the forming tank 13 to be kept warm and moist through the exhaust channel 24 and the exhaust hole 22, ensuring the flexibility of the wood during the forming process.

[0043] To maintain the usage location, for example, such as Figure 5 As shown, a return spring 32 is sleeved on the outer side of the piston rod 3. The two ends of the return spring 32 are in contact with the outer wall of the piston rod 3 and the outer wall of the air delivery head 23, respectively. The piston rod 3 is elastically connected to the air delivery head 23 through the return spring 32.

[0044] During use, the return spring 32 maintains the position of the piston rod 3. When the worker places wood on a flat surface inside the forming groove 13, the piston plate 31 can block the exhaust channel 24 to prevent steam from harming the worker. As the pressing plate 14 moves into the forming groove 13, the push rod 17 pushes the piston rod 3 to move and compresses the return spring 32, so that the steam escapes the blockage of the piston plate 31 and flows inside the exhaust channel 24, achieving moisture retention and heat preservation during the bending process of the wood. After the pressing plate 14 is retracted and reset, the return spring 32 releases its elasticity to push the piston rod 3 and the piston plate 31 to reset, ensuring that the steam flows in a controlled manner inside the exhaust channel 24, thus ensuring the safety of the equipment.

[0045] For controlled exhaust, for example, such as Figure 5 As shown, the piston rod 3 is threaded to the end of a piston plate 31. Both the piston plate 31 and the exhaust channel 24 are designed in a conical shape, and the piston plate 31 is located inside the exhaust channel 24.

[0046] In use, the cooperation between the conical piston plate 31 and the exhaust channel 24 can achieve linear adjustment of airflow. The exhaust can be precisely controlled by controlling the displacement of the piston rod 3, and the conical structure can achieve sealing under the action of the return spring 32.

[0047] To control exhaust, for example, such as Figure 3 As shown, an arc-shaped plate 16 is screwed to the outer wall of the upper end of the extrusion plate 14. The outer wall of the arc-shaped plate 16 is welded with equally spaced parallel push rods 17. The push rods 17 and the piston rod 3 are on the same horizontal plane.

[0048] When in use, the pressing plate 14 moves horizontally, carrying the arc plate 16 and the push rod 17 to move synchronously. When the pressing plate 14 initially contacts the wood, the push rod 17 is in the state of pushing the piston rod 3, so that the piston plate 31 is released from the blockage of the exhaust channel 24, and the steam is discharged at this time.

[0049] In use, the gas supply pipe of the external steam generator is connected to the exhaust channel 24 of the gas supply head 23 via the quick connector 25, and the wood to be bent is placed horizontally on the flat part of the forming groove 13.

[0050] Start the hydraulic rod 11 to push the extrusion plate 14 along the guide rod 15 to move towards the forming groove 13. The arc plate 16 and the top rod 17 move synchronously with the extrusion plate 14. When the extrusion plate 14 approaches the wood, the top rod 17 contacts the piston rod 3 and pushes it inward, compressing the return spring 32. The piston plate 31 is displaced inside the exhaust channel 24, creating a gap between the piston plate 31 and the exhaust channel 24. Steam is sprayed onto the wood surface through the gap and the exhaust hole 22 to maintain the wood's humidity and temperature.

[0051] The extrusion plate 14 continues to advance, pressing the wood into the arc area of ​​the forming groove 13 to achieve precise bending. The limiting rod 2 moves backward synchronously under the push of the top rod 17, compressing the support spring 21, which always keeps the wood above it to prevent it from cracking and splashing. The wood does not come into contact with the compression spring, so it will not affect the compression or release of the compression spring. The air supply head 23 located in the middle continuously sprays air at the bending apex of the wood to maintain the softening effect.

[0052] After the extrusion plate 14 moves to the end point inside the forming groove 13, the hydraulic rod 11 maintains pressure to keep the wood under pressure inside the forming groove 13.

[0053] After bending and forming, the hydraulic rod 11 drives the extrusion plate 14 to exit the forming groove 13, the support spring 21 pushes the limit rod 2 forward to return to the initial position, and the piston rod 3 disengages from the top rod 17. The reset spring 32 pushes the piston rod 3 and piston plate 31 to reset, re-blocking the exhaust channel 24 and stopping the steam injection.

[0054] It should be noted that this utility model is a wood bending and forming device.
