Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument manufacturing, in particular to a plate hot processing and forming device. Background Art

[0002] Solid wood bending refers to a method of bending wood into shape by softening and pressurizing the wood. The curved parts made by this method have natural and smooth lines, beautiful shapes, good strength, and can save labor and materials, and can retain the rich natural texture and color of the wood. Therefore, it is widely used in actual production. Within the normal force range, the wood can be bent, and the stress is eliminated and the original shape is restored; if the stress limit is exceeded, permanent deformation occurs and the fibers split. The commonly used method of bending wood with a small radius is to steam, boil the wood in boiling water or bury it in hot sand to change its fiber properties, increase the elasticity of the wood, and fix it in a fixture in time until the fibers are cooled and dried to be fixed.

[0003] Stringed instruments such as guitars and violins generally include a speaker. A sound hole is provided on one side of the speaker, and a neck is extended from the outer edge of the surface where the sound hole is located. A head is installed at the end of the neck, and strings are provided on the head. The ends of the strings are fixedly connected to the string pegs of the speaker. When in use, the strings are plucked to make the speaker resonate and release the sound waves from the sound hole. The outer edge contour of the speaker is a flat curved surface, and it is often necessary to use a press brake to perform hot bending treatment on the wooden board here. The press brake includes a cabinet with an inclined surface, a telescopic cylinder is fixedly installed on the inclined surface, and the end of the telescopic cylinder is a pressing block. A heating base is provided on the inclined surface to cooperate with the pressing block. When in use, the board is placed between the telescopic cylinder and the heating base. The heating base is provided with a concave module, and the pressing block bends the board for a long time so that the board initially reaches the specified curvature.

[0004] The above-mentioned prior art solutions have the following defects. Since different sound box panels require different curvatures, when some panels have a large curvature, one-time bending can easily cause excessive breakage of the wood fibers of the panels. Therefore, bending is required in steps. When bending in steps, it is necessary to replace the concave modules with larger curvatures. When replacing the concave modules, the heating base needs to be reheated. The operation is cumbersome and the processing time will be further increased. The processing efficiency needs to be improved. Utility Model Content

[0005] The utility model aims to provide a plate hot processing forming device.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] It includes a cabinet body, the outer wall of which is provided with an installation slope, and a plurality of bending units are fixedly installed on the installation slope. The bending units include a telescopic cylinder and a heating base, and the telescopic cylinder and the heating base are spaced apart and arranged on the outer wall of the installation slope. A pressing block is fixedly installed on the end of the telescopic cylinder, and a concave module with a curved concave surface is detachably installed on a side of the heating base close to the pressing block, and the curvature of the concave modules of the bending units are set differently.

[0008] By adopting the above technical scheme, the curvature and concave angle of the concave modules of different bending units are set differently, and the curvature can be set gradually and incrementally. When in use, the plate is first placed in the bending unit with a smaller curvature of the concave module. After the initial bending is finalized, it is moved into the bending unit with a larger curvature for secondary bending. This step is repeated until a suitable bending curvature is reached. Since the heating bases of all bending units are always powered on to maintain a suitable processing temperature and there is no need to replace concave modules with different curvatures, the bending processing rate of the plate can be greatly shortened.

[0009] Furthermore, a heating rod with a wire is slidably embedded in the outer wall of the heating base away from the mounting bevel, and the wire is externally connected to a power supply. A locking groove for a concave module to be engaged is provided on a side of the heating base close to the pressing block, and the locking groove passes through the top wall of the heating base. A locking protrusion matching the locking groove is fixedly provided on a side of the concave module close to the heating base.

[0010] By adopting the above technical solution, the heating rod with a wire can be easily replaced when the heating rod is damaged after working for a long time. The locking protrusion cooperates with the locking groove to have a good limiting effect. Since the locking groove runs through the top wall of the heating base, it can be easily embedded and locked when inserted from the top of the heating base, and can be easily unlocked when pulled out. It is convenient to replace concave modules with different curvatures according to actual needs. The structure is simple and the functional adaptability is strong.

[0011] Furthermore, the heating base is wrapped with a heat-insulating sleeve, the heat-insulating sleeve is penetrated with a processing opening, the curved concave surface of the concave module is matched with the processing opening, the side of the heat-insulating sleeve close to the heating rod wire is penetrated with a matching wire groove, the wire groove is connected to the processing opening, and a pull ring is fixedly installed on the side of the heat-insulating sleeve away from the processing opening.

[0012] By adopting the above technical scheme, the setting of the thermal insulation sleeve can, on the one hand, effectively block the heat loss from the non-working surface of the heating base, and the heat can be concentratedly dissipated from the processing port, so that the power consumption required to reach the specified working temperature is lower. On the other hand, the thermal insulation sleeve wraps the heating base and covers the fixed heating rod, which can effectively reduce the contact area of ​​the heating base exposed to the outside world and prevent the heating base from scalding the operator during operation. The setting of the wire groove facilitates the movement of the heating rod wire. The thermal insulation sleeve and the heating base are in sliding cooperation. When the pull ring is pulled to pull out the thermal insulation sleeve, the heating rod wire passes through the wire groove to avoid obstruction in pulling out the thermal insulation sleeve. The thermal insulation sleeve releases the cover on the heating base, and the heating rod can be smoothly taken out by pulling the wire.

[0013] Furthermore, a fixing plate is extended from the outer edge of the heating base, and an adjustment groove is penetrated through the fixing plate along the length direction of the heating base and the pressing block. The adjusting groove is slidably engaged with a fixing bolt, and the fixing bolt is threadedly connected to the mounting inclined surface. A plurality of anti-slip grooves are provided on one side of the fixing plate close to the mounting inclined surface.

[0014] By adopting the above technical solution, the adjusting groove has a distance adjustment function. Loosen the fixing bolt and then pull the fixing plate. After adjusting the heating base to a suitable position, tighten the fixing plate and the heating base will be firmly fixed in the specified position. The setting of the anti-slip groove can effectively increase the friction between the fixing plate and the mounting inclined surface to prevent the heating base from slipping and deflecting.

[0015] Furthermore, a slope baffle is extended from the bottom wall of the installation slope, and the slope baffle is arranged perpendicular to the installation slope.

[0016] By adopting the above technical solution, the setting of the inclined baffle can effectively prevent the workpieces, equipment parts and other items on the installation inclined surface from falling, and can also be used to temporarily place the plates to be processed, which can effectively improve the convenience of using the equipment.

[0017] In summary, the beneficial technical effects of the utility model are:

[0018] 1. The bending unit with different curvature of concave modules is adopted, so as to ensure that the heating base is always powered on to maintain the appropriate processing temperature and there is no need to replace the concave modules with different curvatures, which greatly shortens the bending processing rate of the plate;

[0019] 2. The use of heat insulation sleeves, processing ports and wire ducts can achieve the effect of energy saving and emission reduction while improving equipment safety;

[0020] 3. A fixed plate and an adjusting slide are used to adjust the distance between the heating base and the pressing block according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

Since the heating bases 22 of all the bending units 2 are always powered on to maintain the appropriate processing temperature and there is no need to replace the concave modules 4 with different curvatures, the bending processing rate of the plate can be greatly shortened. The outer wall of the heating base 22 away from the installation bevel is slidably embedded with a heating rod 5 with a wire 51, and the wire 51 is externally connected to a power supply. The side of the heating base 22 close to the pressing block 3 is provided with a snap-in groove 61 for the concave module 4 to snap-in.

The heating base 22 will be firmly fixed in the specified position. The setting of the anti-skid groove 83 can effectively increase the friction between the fixing plate 8 and the installation inclined surface to prevent the heating base 22 from slipping and deviating.
