[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] The utility model discloses a kind of standardization manufacturing devices of dotal resonance box single board, to solve the problems existing in the above-mentioned related technology, to facilitate the standardization manufacturing of resonance box.

[0027] To make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model is further described in detail with reference to the drawings and specific embodiments.

[0028] Reference Figure 1 The embodiment provides a kind of standardization manufacturing device 100 of dotal resonance box single board, including metal mould, linear drive component and heating device.

[0029] Metal mould is used to clamp straight strip single board, and metal mould includes first metal bending piece 1 and second metal bending piece 2, and first metal bending piece 1 and second metal bending piece 2 are used to clamp straight strip single board from both sides respectively, to bend straight strip single board into the standard bending single board of resonance box.Linear drive component is connected first metal bending piece 1 and second metal bending piece 2 respectively, for making first metal bending piece 1 and second metal bending piece 2 mutually close or far away. Heating device is used to heat first metal bending piece 1 and second metal bending piece 2.

[0030] The working principle of the embodiment dotal resonance box single board standardization manufacturing device 100 is as follows:

[0031] In use, first start heating device, so that the temperature of the metal mold reaches about 200 degrees Celsius. Then, the straight bar of unprocessed veneer is placed between the first metal bending piece 1 and the second metal bending piece 2. Then, the first metal bending piece 1 and the second metal bending piece 2 are moved closer to each other by the linear drive assembly, the straight bar of veneer is clamped and deformed, and the two sides of the straight bar of veneer are respectively attached to the first metal bending piece 1 and the second metal bending piece 2. Then, the metal mold is kept at a temperature of about 20 minutes, and the straight bar of veneer is bent into a standard bending veneer of a concert box (equivalent to a thermoplastic type). Then, the heating device stops heating, and the metal mold naturally cools down, and the clamping state is maintained for at least 12 hours. Finally, the first metal bending piece 1 and the second metal bending piece 2 are separated from each other by the linear drive assembly, and the standard bending veneer of the concert box is taken out.

[0032] Because the shapes of the first metal bending piece 1 and the second metal bending piece 2 are determined, the standard bending veneer with a specific shape can be obtained, the consistency of the shape of the standard bending veneer is improved, and the consistency of the tone of the Dohr concert box made of the standard bending veneer is improved, the difficulty of production is reduced, and the cultural heritage of Dohr is facilitated.

[0033] As a possible example, in the embodiment, the linear drive assembly includes a bidirectional screw 3 and a bearing seat. The two threaded segments of the bidirectional screw 3 are respectively threadedly connected with the first metal bending piece 1 and the second metal bending piece 2, and the bidirectional screw 3 is matched with the shaft hole of the bearing seat. By rotating the bidirectional screw 3, the first metal bending piece 1 and the second metal bending piece 2 can be moved closer to or away from each other, which is convenient for operation. It can be understood that the bidirectional screw 3 referred to in the embodiment should have self-locking performance, so that after the first metal bending piece 1 and the second metal bending piece 2 are moved close to each other to the minimum distance, the bidirectional screw 3 can no longer be driven to rotate, and at this time the bidirectional screw 3 will not rotate.

[0034] As a possible example, in the embodiment, the first metal bending piece 1 and the second metal bending piece 2 each include a bending piece body and a connecting block, the connecting block is fixedly connected with the bending piece body, and the connecting block is threadedly connected with the bidirectional screw 3. Because the bending piece body is curved in shape, it is difficult to process internal threads thereon. Therefore, in the embodiment, the internal threads are arranged on the connecting block, so as to reduce the processing difficulty. The connecting block and the bending piece body can be connected by welding, or connected by screws or other fasteners, or connected by other commonly used connection methods.

[0035] As a possible example, in the embodiment, the linear drive assembly further includes a guide rail, and the connecting block is slidingly installed on the guide rail. The guide rail guides the connecting block to ensure that the connecting block moves along a straight line.

[0036] As a possible example, in the embodiment, the linear drive assembly further includes a handle 4, and the handle 4 is connected to one end of the bidirectional screw 3. By rotating the handle 4, the bidirectional screw 3 can be driven.

[0037] However, the actual implementation is not limited thereto. For example, the linear drive assembly can further comprise a driving motor, which is in transmission connection with the bidirectional screw 3, so that the bidirectional screw 3 is driven to rotate by the driving motor.

[0038] As a possible example, in the embodiment, the metal mold is an iron mold. The iron mold has relatively good shape retention ability, heat conductivity, and low purchase cost. According to actual needs, a person skilled in the art can also select metal molds of other materials.

[0039] As a possible example, in the embodiment, the heating device comprises a first heating resistor and a second heating resistor, the first heating resistor is connected to the first metal bending piece 1, and the second heating resistor is connected to the second metal bending piece 2. By passing current through the first heating resistor and the second heating resistor, the first metal bending piece 1 and the second metal bending piece 2 can be heated.

[0040] As a possible example, in the embodiment, the heating device further comprises a heating controller and a thermistor. The heating controller is electrically connected to the first heating resistor and the second heating resistor through the wires 5, respectively, for providing electric energy to the first heating resistor and the second heating resistor. The thermistor is attached to the metal mold and is electrically connected to the heating controller, for feeding back the temperature of the metal mold to the heating controller. The heating device adjusts the current according to the temperature fed back by the thermistor, so as to maintain the temperature of the first metal bending piece 1 and the second metal bending piece 2 at about 200 degrees Celsius, avoiding too high or too low temperature.

[0041] As a possible example, in the embodiment, the first metal bending piece 1 and the second metal bending piece 2 are both attached with thermistors, so as to monitor the temperature of the first metal bending piece 1 and the second metal bending piece 2 simultaneously, and make the temperature on both sides of the straight strip veneer consistent.

[0042] The principle and implementation mode of the specific examples are described in the utility model, and the above embodiment is only used to help understand the method and core idea of the utility model; meanwhile, for the general skilled in the art, according to the idea of the utility model, the specific implementation mode and application range will be changed. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
