[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine for speaker power pins. Background Art

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a base shell, a coil and a cover plate. The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate.

[0003] During the production process of the electrical connection pins of the speaker, the electrical connection pins need to be bent, and the electrical connection pins will be bent by a bending machine.

[0004] However, the electrical connection pins of the speaker are small in size, and it is inconvenient to fix the electrical connection pins with a fixing device when bending them. The existing electrical connection pin fixing device of the bending machine can only bend one electrical connection pin at a time, so manual operation is required, which is time-consuming and labor-intensive and reduces the work efficiency of the staff.

[0005] Moreover, the existing fixing device of the bending machine docking pin can only fix the electrical connecting pins of the same size. When it is necessary to fix the electrical connecting pins of different sizes, different fixing devices need to be replaced, which is troublesome and cumbersome. Utility Model Content

[0006] The purpose of the present utility model is to provide a speaker power pin bending machine to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a speaker power pin bending machine, comprising:

[0008] main body;

[0009] A limit block located on one side of the main body, the limit block is used to limit the position of the connecting pin during bending;

[0010] A bending plate is provided on one side of the top of the main body, and the bending plate is connected to the main body through a hydraulic device. One side of the main body is connected to the bracket through a fastener. The inner side of the bracket is connected to the two ends of the tensioning roller through a rotating shaft. The outer wall of the tensioning roller is sleeved with a conveyor belt, and the outer wall of the conveyor belt is connected to the bottom of the support block through fasteners. An extension block is provided on one side of the support block, and one side of the bending plate is connected to the support column through a fastener. The bottom of the support column is connected to the telescopic column in an embedded form.

[0012] Preferably, one side of the top of the connecting plate is connected to the moving blocks through a fixed column, the moving blocks are distributed at equal intervals on the connecting plate, and a collecting groove is provided below one end of the main body.

[0013] Preferably, the middle portion of the bracket is connected to a support ring via a fastener, the support ring is located in the middle portion of the conveyor belt, and the inner side of the conveyor belt is connected to an outer wall of the support ring by sliding.

[0014] Preferably, one side of the support block is connected to one end of the support plate in an embedded manner, and one end of the support plate away from the support block is connected to the extension block through a fastener.

[0015] Preferably, the bottom of the support block is connected to the threaded column via a rotating shaft, one end of the threaded column is connected to the threaded block via a thread, the top of the threaded block is connected to the bottom of the extension block via a fastener, and one end of the threaded column is connected to the knob via a fastener.

[0016] Preferably, the internal fastener of the support column is connected to one end of the elastic member, the fastener at the other end of the elastic member is connected to the telescopic column, the telescopic column fastener is connected to the protrusion, the two sides of the protrusion are connected to the inner side of the connecting block through a rotating shaft, and the bottom of the connecting block is connected to the limit block through a fastener.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] First, the utility model can bend multiple electrical pins at the same time by setting a limit block and a conveyor belt. The electrical pins that need to be bent are placed on the inner side of the support block and the extension block, and the motor is turned on. The motor drives the tensioning roller to rotate through the output shaft, and the tensioning roller drives the electrical pins on the support block and the extension block to move through the conveyor belt. After the electrical pins are placed on the support block and the extension block on the conveyor belt, the cylinder is turned on, and the cylinder drives the connecting plate to move through the output end. The connecting plate pushes the position where the connecting pins need to be bent to the bottom of the bending plate through the moving block, and the main body is opened. The main body drives the bending plate downward through the hydraulic device to bend the connecting pins. When bending, during the movement of the bending plate, the limit block at the bottom of the support column will be driven to move and move it to the top of the connecting pin. During the process of squeezing and bending the connecting pin, one end of it will be tilted. The tilted connecting pin pushes the limit block to drive the connecting block to rotate on the protrusion, and at the same time drives the telescopic column to enter the inside of the support column to prevent the connecting pin from tilting during the bending process. After the bending is completed, the bending plate rises, and through the rebound force of the elastic part, the elastic part pushes the limit block to move through the telescopic column, and the limit block pushes the connecting pin to fall on the support block and the extension block again, so as to achieve the effect of automatically bending multiple connecting pins at the same time, saving time and effort, and effectively improving work efficiency.

[0019] Second, the present invention is capable of bending speaker connector pins of different sizes by providing a support plate and a threaded column. Before bending the connecting pins, the threaded column is rotated by a knob according to the size of the connecting pins. The threaded column drives the threaded block to move through the thread, and the threaded block drives the extension block to move. The extension block drives the support plate to move inside the support block until the inner sides of the support block and the extension block fit the size of the speaker connector pins. This can achieve the effect of enabling this device to support and fix speaker connectors of different sizes, reflecting the practicality of this device. BRIEF DESCRIPTION OF THE DRAWINGS

The main body 1 drives the bending plate 2 to move downward through the hydraulic device to bend the connecting pin. In the process of moving the bending plate 2, it drives the limit block 6 at the bottom of the support column 19 to move, so that it moves to the top of the connecting pin.

[0033] Specifically, one side of the top of the connecting plate 7 is connected to the moving blocks 12 through a fixed column. The moving blocks 12 are distributed at equal intervals on the connecting plate 7. A collecting tank 10 is provided below one end of the main body 1.

[0039] Specifically, the bottom of the support block 5 is connected to the threaded column 17 through a rotating shaft, one end of the threaded column 17 is connected to the threaded block 16 through a thread, the top of the threaded block 16 is connected to the bottom of the extension block 11 through a fastener, and one end of the threaded column 17 is connected to the knob 18 through a fastener.

[0042] Through the above technical solution, the protrusion 22 and the connecting block 23 are used to enable the limit block 6 to adjust the angle together with the connecting pin when the connecting pin is bent and tilted, and can always be located at the top of the connecting pin to limit the connecting pin without manual operation, saving time and effort.

[0043] When in use, first, before bending the docking pin, according to the size of the connecting pin, turn the threaded column 17 through the knob 18, and the threaded column 17 drives the threaded block 16 to move through the thread, and the threaded block 16 drives the extension block 11 to move, and the extension block 11 drives the support plate 15 to move inside the support block 5 until the inner side of the support block 5 and the extension block 11 fits the size of the speaker connecting pin, and then place the electrical connecting pin that needs to be bent on the inner side of the support block 5 and the extension block 11, turn on the motor 9, and the motor 9 drives the tensioning roller 14 to rotate through the output shaft, and the tensioning roller 14 drives the electrical connecting pins on the support block 5 and the extension block 11 to move through the conveyor belt 4, so that the middle part of all the support blocks 5 is located on one side of the moving block 12, and after the electrical connecting pins are placed on the support block 5 and the extension block 11 on the conveyor belt 4, turn on the cylinder 8, and the cylinder 8 drives the engagement pin 12 through the output end When the connecting plate 7 moves, the connecting plate 7 pushes the position where the connecting pin needs to be bent to the bottom of the bending plate 2 through the moving block 12, and the main body 1 is opened. The main body 1 drives the bending plate 2 to move downward through the hydraulic device to bend the connecting pin. In the process of moving the bending plate 2, it will drive the limit block 6 at the bottom of the support column 19 to move it to the top of the connecting pin. In the process of squeezing and bending the connecting pin, one end of the connecting pin will tilt. The tilting of the connecting pin pushes the limit block 6 to drive the connecting block 23 to rotate on the protrusion 22, and at the same time drives the telescopic column 20 to enter the inside of the support column 19 to prevent the connecting pin from tilting during the bending process. After the bending is completed, the bending plate 2 rises, and through the rebound force of the elastic member 21, the elastic member 21 pushes the limit block 6 to move through the telescopic column 20, and the limit block 6 pushes the connecting pin to fall on the support block 5 and the extension block 11 again, and the work is completed.
