Description

Technical Field

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

[0002] A bending machine is a tool used to shape and process sheet metal. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being formed. It is a tool used to make the blank into a part with a specific shape and size under the pressure of the bending machine.

[0003] For example, application number CN201573248U discloses a solid wood bending and forming device to solve the problem of solid wood bending and forming. It includes an inner mold, an outer mold, and a top block. The inner mold is an integral structure, with one end connected to a pressure-applying drive device and the other end being an arc-shaped forming head. The outer mold consists of two symmetrically arranged split modules, each connected to a machine base by a hinge shaft. The side of each split module closest to the workpiece has an arc-shaped forming surface that matches the arc-shaped forming head of the inner mold. In this invention, the wood to be processed is placed between the inner and outer molds. Under the action of the pressure-applying drive device, the inner mold applies pressure to the wood. The two split modules of the outer mold naturally rotate around the hinge shaft as the wood bends and deforms. During processing, the inner and outer molds tightly wrap around the wood, resulting in uniform stress on the wood. Furthermore, the outer mold can rotate naturally with the wood deformation without the need for other devices. This invention has advantages such as simple structure, low processing cost, and reliable processing quality.

[0004] However, this type of solid wood bending and forming device cannot be heated during use, which makes the wood board prone to springback and deformation after bending, failing to achieve the required degree of bending. At the same time, the dust and wood chips generated during the bending process cannot be cleaned up in time, causing the wood chips to be squeezed and adhered to the surface, which does not meet people's needs. Therefore, a wood bending device is needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as the inability to heat treat, the tendency of wooden boards to bend and spring back, the inability to promptly remove sawdust that could damage the template surface, and low processing efficiency, this utility model provides a wood bending device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses a wood bending device, including a base and a connecting mechanism disposed inside the base. The connecting mechanism includes a pressure component, a heating component, and a cleaning component.

[0008] The pressurizing assembly includes a frame, a hydraulic press, a lifting plate, mounting bolts, and a fixing mold. The upper surface of the base is welded with a frame, and a hydraulic press is fixedly installed on the inner top wall of the frame. A lifting plate is fixed to the output end of the hydraulic press, and a fixing mold is fixedly installed on the inner bottom of the base by mounting bolts.

[0009] The heating assembly includes a heating coil and a terminal block. The heating coil is embedded inside the fixed mold, and the terminal block is fixedly installed on the front surface wall of the fixed mold. The two ends of the heating coil pass through the fixed mold and are fixedly connected to the terminal block.

[0010] The cleaning assembly includes a vacuum motor and a dust collection box. The vacuum motor is fixedly installed on the rear side wall of the frame, and the dust collection box is provided on the lower surface wall of the vacuum motor.

[0011] As a preferred embodiment of this utility model, the lifting plate is fixedly installed with a pressing mold by fastening bolts, and the pressing mold is located directly above the fixed mold.

[0012] As a preferred technical solution of this utility model, a heating iron sheet is embedded in the upper surface wall of the fixed mold, and a shaping iron sheet is embedded in the lower surface wall of the pressing mold. The heating iron sheet and the shaping iron sheet have a concave-convex structure, and the heating iron sheet and the shaping iron sheet have the same length.

[0013] As a preferred technical solution of this utility model, a dust extraction pipe is screwed to the bottom of the dust collection box, and the end of the dust extraction pipe away from the dust collection box passes through and is screwed to the side wall of the frame.

[0014] As a preferred embodiment of this utility model, a viewing window is provided on the outer side wall of the frame, and a dust blower is fixedly installed on the frame, with a dust blowing hose sealed and screwed to the output end of the dust blower.

[0015] As a preferred embodiment of this utility model, a central controller is provided on one side of the frame, the central controller is fixedly installed on the base, and a frame is also installed on the other side of the central controller.

[0016] This utility model has the following beneficial effects:

[0017] By setting up a heating coil, terminals, heating sheet and shaping sheet, when working, the terminals provide current to the heating coil, the heating coil generates an alternating magnetic field, which causes the heating sheet and shaping sheet to generate induced current, thereby generating heat. The heating sheet and shaping sheet heat the wooden board sandwiched in the middle, making the wooden board easier to deform, while drying the moisture in the wooden board, making the wooden board easier to shape.

[0018] By setting up a vacuum motor, dust collection box, dust extraction pipe, dust blower, and dust blowing hose, after the bent wood is removed, the worker starts the dust blower, holds the dust blowing hose, and blows air onto the heated iron sheet surface to ensure that there are no sawdust residues on the heated iron sheet surface, thus ensuring that the surface of the next piece of wood to be bent is clean. At the same time, the vacuum motor starts working, extracting moisture and debris from inside the frame through the dust extraction pipe. The sawdust and debris are collected inside the dust collection box for easy cleaning by the worker. Attached Figure Description

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example 1

[0027] like Figure 1-5 As shown, the present invention proposes a wood bending device, which includes a base 1 and a connecting mechanism disposed inside the base 1. The connecting mechanism includes a pressurizing component, a heating component and a cleaning component.

[0028] The pressurizing assembly includes a frame 2, a hydraulic press 3, a lifting plate 4, mounting bolts 5, and a fixed mold 6. The frame 2 is welded to the upper surface of the base 1. The hydraulic press 3 is fixedly installed on the inner top wall of the frame 2. The lifting plate 4 is fixed to the output end of the hydraulic press 3. The fixed mold 6 is fixedly installed on the inner bottom of the base 1 by mounting bolts 5. During operation, by setting the mounting bolts 5 and the fixed mold 6, when it is necessary to change the mold, the mounting bolts 5 are unscrewed and the fixed mold 6 is removed, so that different molds can be replaced. The mold replacement operation is simple and has a wider range of applications.

[0029] The heating assembly includes a heating coil 7 and a terminal 8. The heating coil 7 is embedded inside the fixed mold 6, and the terminal 8 is fixedly installed on the front surface of the fixed mold 6. The two ends of the heating coil 7 pass through the fixed mold 6 and are fixedly connected to the terminal 8. During operation, by setting the heating coil 7 and the terminal 8, the terminal 8 provides current to the heating coil 7, and the heating coil 7 generates an alternating magnetic field, which facilitates the subsequent heating of the sheet metal 13 and the shaping sheet metal 14 to generate induced current, thereby generating heat to bake and shape the wood to be processed.

[0030] Furthermore, the lifting plate 4 is fixedly installed with a pressing mold 12 by fastening bolts 11. The pressing mold 12 is located directly above the fixed mold 6. During operation, by setting the fastening bolts 11 and the pressing mold 12, the pressing mold 12 can be removed by unscrewing the fastening bolts 11, and different molds can be replaced. The mold replacement operation is simple and has a wider range of applications.

[0031] Furthermore, a heating sheet 13 is embedded in the upper surface of the fixed mold 6, and a shaping sheet 14 is embedded in the lower surface of the pressing mold 12. The heating sheet 13 and the shaping sheet 14 have a concave-convex structure, and their lengths are exactly the same. During operation, by setting the heating sheet 13 and the shaping sheet 14, the terminal 8 provides current to the heating coil 7. The heating coil 7 generates an alternating magnetic field, which causes the heating sheet 13 and the shaping sheet 14 to generate induced current, thereby generating heat. The heating sheet 13 and the shaping sheet 14 heat the wooden board clamped in the middle, making the wooden board easier to deform and drying the moisture in the wooden board, making the wooden board easier to shape.

[0032] Furthermore, a central controller 19 is provided on one side of the frame 2. The central controller 19 is fixedly installed on the base 1. The frame 2 is also installed on the other side of the central controller 19. During operation, the frame 2 is set up with two sets, which are controlled by the central controller 19. When one set of the frame 2 is performing bending operation, the other set of the frame 2 can perform unloading, cleaning and loading operations, and work repeatedly, resulting in higher processing efficiency.

[0033] Example 2

[0034] like Figure 1-5As shown, the wood bending device proposed in this utility model, compared with embodiment 1, is another implementation of this utility model. The cleaning component includes a vacuum motor 9 and a dust collection box 10. The vacuum motor 9 is fixedly installed on the rear side wall of the frame 2, and the dust collection box 10 is provided on the lower surface wall of the vacuum motor 9. During operation, by setting up the vacuum motor 9 and the dust collection box 10, the vacuum motor 9 draws moisture and debris from inside the frame 2 into the dust collection box 10 for collection, which is convenient for workers to clean.

[0035] Furthermore, a dust collection pipe 15 is screwed to the bottom of the dust collection box 10. The end of the dust collection pipe 15 away from the dust collection box 10 passes through and is screwed to the side wall of the frame 2. During operation, by setting up the dust collection box 10 and the dust collection pipe 15, the dust collection motor 9 starts to work and draws out moisture and debris inside the frame 2 through the dust collection pipe 15, making it convenient for subsequent cleaning by staff.

[0036] Furthermore, a viewing window 16 is provided on the outer wall of the frame 2, and a dust blower 17 is fixedly installed on the frame 2. The output end of the dust blower 17 is sealed and screwed with a dust blowing hose 18. During operation, by setting up the viewing window 16, the dust blower 17, and the dust blowing hose 18, after the bent wood is removed, the operator starts the dust blower 17, holds the dust blowing hose 18, and blows air onto the surface of the heated iron sheet 13, so that there are no wood chips or residues on the surface of the heated iron sheet 13, ensuring that the surface of the next piece of wood to be bent is clean. The viewing window 16 makes it easier for the operator to observe, and also protects the operator, preventing wood chips from flying out when pressing down the wood and causing personal injury. Safety is guaranteed.

[0037] During operation, the wooden board is first placed on top of the fixed mold 6. Then, the hydraulic press 3 starts working, and the hydraulic press 3 drives the lifting plate 4 to move downward. The pressing mold 12 installed on the lower surface of the lifting plate 4 moves downward as well, so that the shaping iron sheet 14 embedded on the surface of the pressing mold 12 squeezes the wooden board to be bent, so that the wooden board to be bent is bent and shaped in the heated iron sheet 13 on the fixed mold 6. The hydraulic press 3 stabilizes the pressure for a period of time to facilitate the subsequent heating treatment of the wooden board.

[0038] Next, the terminal 8 supplies current to the heating coil 7, which generates an alternating magnetic field, causing the heating sheet 13 and the shaping sheet 14 to generate induced current, which in turn generates heat. The heating sheet 13 and the shaping sheet 14 heat the wooden board clamped in the middle, making the wooden board easier to deform and drying the moisture in the wooden board, making the wooden board easier to shape. After heating is completed, the terminal 8 is de-energized, and the hydraulic press 3 drives the lower pressing mold 12 to move upward, so that the bent wood can be taken out.

[0039] Finally, after removing the bent wood, the worker starts the blower 17, holds the blower hose 18, and blows air onto the surface of the heated sheet metal 13 to ensure there are no sawdust residues on the surface, guaranteeing a clean surface for the next piece of wood to be bent. Simultaneously, the vacuum motor 9 starts working, extracting moisture and debris from inside the frame 2 through the suction pipe 15. The sawdust and debris are collected inside the dust collection box 10 for easy cleaning. When changing molds, the viewing window 16 is removed, the fixed mold 6 is removed by unscrewing the mounting bolts 5, and the lower mold 12 is removed by unscrewing the fastening bolts 11. This allows for easy mold replacement and wider applicability. The frame 2 has two sets, allowing one set to perform bending operations while the other set performs unloading, cleaning, and loading operations, creating a cyclical process for higher processing efficiency.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
