Description

Technical Field

[0001] The present invention relates to the technical field of piano processing, and specifically, it is a piano damper rod bending and deforming device. Background Art

[0002] A piano is composed of keys and a metal string soundboard. Generally, the range of an 88-key piano almost encompasses all the musical notes in the musical scale system, making it one of the musical instruments with the widest range. It is commonly used for solo, ensemble, and accompaniment. The modern piano has a wide range, diverse timbres, and excellent expressiveness. It can not only be used as a solo, ensemble, or accompaniment instrument but is also an essential basic instrument in music creation and auditory training. The damper rod is an essential accessory in a piano, and the quality of the damper rod will affect the sound quality of the piano body during playing. Therefore, precise operation is required when bending the damper rod.

[0003] Based on the above, the inventor found that the existing piano damper rod bending and deforming device mainly has the following deficiencies. For example, when bending the damper rod, it needs to be processed with flat-nose pliers, which makes the angle when bending the damper rod unable to be fixed, resulting in inconsistent bending angles of multiple groups of processed damper rods and affecting the sound quality of the piano.

[0004] Therefore, a piano damper rod bending and deforming device needs to be proposed. Summary of the Invention

[0005] In view of the above problems, when bending the damper rod, it needs to be processed with flat-nose pliers, which makes the angle when bending the damper rod unable to be fixed, resulting in inconsistent bending angles of multiple groups of processed damper rods and affecting the sound quality of the piano. The present invention provides a piano damper rod bending and deforming device.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A piano damper rod bending and deforming device, its structure includes a main body, a top cover, a control panel, and a speaker. The top cover is provided at the top of the main body. The control panel is arranged at the front end of the top of the main body. The speaker is located at the front end of the main body. The main body includes a support base, a bending device, a support device, and a damper rod. The support base is arranged at the bottom of the main body. The bending device is arranged at the inner top of the main body. There are two support devices, and the support devices are respectively arranged on both end faces of the bending device. The damper rod is placed on the top of the support device. The bending device includes a support plate, sliding grooves, a bending structure, a support frame, a threaded rod, and a servo motor. The support plate is arranged inside the main body. There are two sliding grooves, which are respectively arranged on the left and right sides of the support plate. There are two bending structures, and the bending structures are respectively slidably connected to the sliding grooves. There are two support frames fixedly installed at the front and rear ends inside the main body. The threaded rod is engaged with the support frame, and the servo motor is meshed with the threaded rod; Both sides of the threaded rod are reverse threads, and at the same time, both sides of the threaded rod are respectively threadedly connected to the two bending structures; The bending structure includes a bending block, a clamping rod, a support rod, and a threaded tube. A clamping rod is arranged at the bottom of the bending block. The clamping rod is slidably connected to the sliding groove. The support rod is fixedly connected to the rear end face of the bending block. The threaded tube is fixedly connected to the bottom end face of the bending block; The bending block includes a bending groove and a protective pad. The bending groove is arranged on the side end face of the bending block. The protective pad is made of rubber, and the protective pad is attached to the inner end face of the bending groove; By placing the sound insulation rod on the end face of the support device and then covering the top cover, and controlling the servo motor to work through the control panel, the threaded rod can move towards the middle in cooperation with the threaded tube under the drive of the servo motor, so that the two bending blocks clamp and bend the sound insulation rod. During the sliding process of the bending block, the clamping rod can support it to improve stability. Then, the arc-shaped bending groove can guide the sound insulation rod, so that the sound insulation rod can be stably clamped and bent by the two bending blocks. And the protective pad can play a protective role for the sound insulation rod to avoid damage to the sound insulation rod caused by friction. Thus, the sound insulation rod can be automatically bent, and at the same time, the angle at which the sound insulation rod is bent is also fixed, avoiding inconsistent bending angles of the sound insulation rod.

[0007] Among them, the support device includes a mounting seat, a support seat, and a return spring. The mounting seat is arranged at the side end inside the main body. There are four return springs, and the return springs are installed on both sides inside the mounting seat; By placing the sound insulation rod on the end face of the support seat, the sound insulation rod can be clamped and bent by the bending structure. At the same time, when the sound insulation rod is being bent, the sliding block at the bottom of the support tray can also squeeze the return spring to move, so that the support tray can also support the sound insulation rod after the sound insulation rod is bent and deformed.

[0008] Among them, the support seat includes a sliding block, a spring groove, and a support tray. The sliding block is clamped and installed inside the mounting seat. There are four spring grooves, and the spring grooves are respectively arranged on both side end faces of the sliding block. The support tray is fixedly installed on the top end face of the sliding block; By positioning the return spring through the spring groove, the stability of the return spring driving the sliding block to reset can be maintained.

[0009] Among them, the reset spring is movably matched with the sliding block; the sliding block is reset by the reset spring.

[0010] Among them, the support tray is in a semi-circular ring shape; it is convenient to support the damper rod through the support tray.

[0011] Among them, the damper rod can be placed on the end face of the support tray. Beneficial effects

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention utilizes the threaded rod to be threadedly matched with the threaded tube and move towards the middle under the drive of the servo motor, so that the two bending blocks clamp and bend the damper rod, and the damper rod can be automatically bent. At the same time, the angle at which the damper rod is bent is also fixed, avoiding inconsistent bending angles of the damper rod.

[0013] 2. The present invention utilizes the damper rod to be placed on the end face of the support seat, and the damper rod can be clamped and bent by the bending structure. At the same time, when the damper rod is bent, the sliding block at the bottom of the support tray can also squeeze the reset spring to move, avoiding the situation that the damper rod falls after being bent.

[0024] Embodiment 1: Please refer to Figures 1-5 , the specific embodiments of the present invention are as follows: Its structure includes a main body 1, a top cover 2, a control panel 3, and a speaker 4. A top cover 2 is provided on the top of the main body 1. The control panel 3 is arranged at the front end of the top of the main body 1. The speaker 4 is located at the front end of the main body 1. The main body 1 includes a support base 11, a bending device 12, a support device 13, and a sound damping rod 14. The support base 11 is arranged at the bottom of the main body 1.

There are two support devices 13, and the support devices 13 are respectively arranged on the two side end faces of the bending device 12. The sound damping rod 14 is placed on the top of the support device 13; The bending device 12 includes a support plate 111, a sliding groove 112, a bending structure 113, a support frame 114, a threaded rod 115, and a servo motor 116. The support plate 111 is arranged inside the main body 1. There are two sliding grooves 112, and the sliding grooves 112 are respectively arranged on the left and right sides of the support plate 111. There are two bending structures 113, and the bending structures 113 are respectively slidably connected to the sliding grooves 112. There are two support frames 114 fixedly installed at the front and rear ends inside the main body 1. The threaded rod 115 is engaged with the support frame 114. The servo motor 116 is meshed with the threaded rod 115; Both sides of the threaded rod 115 have reverse threads, and at the same time, both sides of the threaded rod 115 are respectively threadedly connected to two bending structures 113; The bending structure 113 includes a bending block 1131, a clamping rod 1132, a support rod 1133, and a threaded tube 1134.

The support rod 1133 is fixedly connected to the rear side end face of the bending block 1131. The threaded tube 1134 is fixedly connected to the bottom end face of the bending block 1131; The bending block 1131 includes a bending groove 51 and a protective pad 52. The bending groove 51 is provided on the side end face of the bending block 1131. The protective pad 52 is made of rubber and is attached to the inner end face of the bending groove 51. By placing the sound insulation rod 14 on the end face of the support device 13, covering the top cover 2, and controlling the servo motor 116 to work through the control panel 3, the threaded rod 115 can be threadedly engaged with the threaded tube 1134 and move towards the middle under the drive of the servo motor 116, so that the two bending blocks 1131 clamp and bend the sound insulation rod 14.

[0025] Based on the above embodiments, the specific working principle is as follows: Place the sound insulation rod 14 on the end face of the support device 13, cover the top cover 2, and control the servo motor 116 to work through the control panel 3, so that the threaded rod 115 can be threadedly engaged with the threaded tube 1134 and move towards the middle under the drive of the servo motor 116, allowing the two bending blocks 1131 to clamp and bend the sound insulation rod 14. During the sliding process of the bending block 1131, the stability can be improved by supporting through the engaging rod 1132. The sound insulation rod 14 can be guided through the arc-shaped bending groove 51, so that the sound insulation rod 14 can be stably clamped and bent by the two bending blocks 1131. The protective pad 52 can protect the sound insulation rod 14 and prevent it from being damaged by friction. Thus, the sound insulation rod 14 can be automatically bent, and the bent angle of the sound insulation rod 14 is also fixed, avoiding inconsistent bending angles of the sound insulation rod 14.

[0030] The sound damping rod 14 can be placed on the end face of the support tray 1333.

[0031] Based on the above embodiments, the specific working principle is as follows: By placing the sound damping rod 14 on the end face of the support seat 132, the sound damping rod 14 can be clamped and bent by the bending structure 113. At the same time, when the sound damping rod 14 is bent, the sliding block 1331 at the bottom of the support tray 1333 can also squeeze the reset spring 133 to move, so that the support tray 1333 can support the sound damping rod 14 after it is bent. By setting the shape of the support tray 1333 to a semi-circular shape, the support tray 1333 can stably support the sound damping rod 14, preventing the sound damping rod 14 from falling. Thus, the effect of automatically bending the sound damping rod 14 can be achieved, and the bent angle of the sound damping rod 14 can be fixed, preventing the bent angles of the processed sound damping rods 14 from being inconsistent.
