Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tools for frets of guitar-type stringed instruments, and in particular to a fret bending device. Background Technology
[0002] Frets: Also known as fret wires or fret posts, they are generally made of metal. The quality of the frets has a certain impact on the feel of playing the guitar. To ensure the guitar's intonation and playing comfort, a fret bender is used to adjust the curvature of the frets. However, the fret benders used now are all open-type, which can easily cause the frets to bend sideways during the bending process, greatly reducing the accuracy and making the bent frets unusable, resulting in a great deal of waste.
[0003] In view of the above problems, a filament bending device is proposed to improve the stability during the filament bending process. Utility Model Content
[0004] In view of the above-mentioned technical problems, this utility model provides a wire bending device, which adopts an innovative combined design to reduce the lateral displacement of the wire during the bending process, improve the stability of the wire bending process, and ensure a higher bending success rate.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A wire bending device, characterized in that it includes a main board A, a main board B, a wire bending guide rail, a wire limiting and fixing block, a fixing pin, and an adjusting screw. The main board A and main board B are fixedly connected by multiple sets of mounting screws. The wire bending guide rail is installed in a mounting groove on the main board A by the fixing pin. A wire limiting and fixing block is located above the wire bending guide rail and is mounted on the main board A by the fixing pin. A threaded hole is provided at the bottom of the mounting groove on the main board A, and an adjusting screw is threaded into the threaded hole.
[0007] The main board A is provided with a wire placement groove, which is perfectly aligned with the guide rail groove on the wire bending guide rail.
[0008] Furthermore, the bottom of the wire limiting and fixing block is provided with a wire limiting groove, which is located above the guide groove of the wire bending guide rail.
[0009] Specifically, the adjusting screw is an M3 screw specifically designed for bending guide rails under pressure.
[0010] The beneficial effects of this utility model are:
[0011] In use, the wire is inserted into the guide groove of the wire bending guide rail and the wire placement groove of the main board A. The wire limiting and fixing block above the wire bending guide rail restricts the lateral displacement of the wire during the bending process, ensuring a higher success rate of wire bending. This not only improves work efficiency but also reduces wire waste caused by bending failure.
[0012] This invention allows for precise adjustment of the fingerboard curvature by operating the adjusting screw below the main board A. During the upward movement, the screw pushes one end of the guide rail under the force of the fingerboard, causing it to tilt upward. This satisfies the need to adjust different fingerboard curvatures and can be precisely adjusted within the range of 14R to 7-1 / 4R. Furthermore, the operation of adjusting the fingerboard curvature is simple and convenient. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0021] Example 1
[0022] As shown in the figure, the wire bending device includes a main board A (1), a main board B (2), a wire bending guide rail 4, a wire limiting and fixing block 5, a fixing pin 7, and an adjusting screw 6. The main board A (1) and the main board B (2) are fixedly connected by multiple sets of mounting screws 3. The wire bending guide rail 4 is installed in the mounting groove 12 set on the main board A (1) by the fixing pin 7. The guide rail groove on the wire bending guide rail 4 and the wire placement groove 11 set on the main board A (1) are perfectly aligned at the port connection.
[0023] A wire limiting and fixing block 5 is provided above the wire bending guide rail 4. The wire limiting and fixing block 5 is installed on the main board A (1) by fixing pin 7. The bottom of the wire limiting and fixing block 5 is provided with a wire limiting groove 51. The wire limiting groove 51 is located above the guide rail groove 41 of the wire bending guide rail 4.
[0024] like Figure 4 The mounting slot 12 of the motherboard A(1) has a threaded hole 13 at the bottom, and an adjusting screw 6 is threaded in the threaded hole 13. The adjusting screw 6 is an M3 screw specially used for bending guide rail 4 under the force of the wire.
[0025] In use, the frets are inserted into the guide groove 41 of the fret bending guide 4 and the fret placement groove 11 of the main board A (1). Then, the adjusting screw 6 connected to the threaded bottom of the main board A (1) is operated according to the required curvature. When the adjusting screw 6 is rotated, it moves upward. During the upward movement, the end of the adjusting screw pushes the fret bending guide 4 in the mounting groove 12 of the main board A (1). Since one end of the fret bending guide 4 is installed on the main board A (1) through the fixing pin 7, the other end of the fret bending guide 4 will bend upward when pushed by the adjusting screw 6, thus meeting the adjustment requirements. Moreover, by operating the adjusting screw 6, the degree of upward bending of the fret bending guide 4 can be adjusted, and the frets of the instrument can be precisely adjusted within the range of 14R to 7-1 / 4R, thereby meeting the requirements for adjusting different fingerboard curvatures.
[0026] In addition, during the bending process, the wire is restricted by the wire limiting and fixing block 5 located above the wire bending guide 4, which prevents the wire from shifting laterally during the bending process, thereby ensuring a higher bending success rate. This not only improves work efficiency but also reduces wire waste caused by bending failures.
[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
