Description

Technical Field

[0001] This invention relates to the field of bending machine equipment technology, and in particular to a double fixed blade independent motion mechanism for a bending machine. Background Technology

[0002] A letter bending machine is a tool used to create metal letters and signs, playing a vital role in the advertising, signage, and architectural decoration industries. With advancements in urbanization and the diversification of the business environment, the demand for high-quality, customized signage is constantly increasing. While traditional manual methods can achieve certain results, they are inefficient and inconsistent. Therefore, the advent of letter bending machines has greatly improved production efficiency and precision. Through mechanization, letter bending machines can quickly and accurately bend metal materials into various shapes to meet diverse design requirements. Furthermore, letter bending machines are suitable for various metal materials, including aluminum, copper, and stainless steel, making them an indispensable piece of equipment in the modern advertising and decoration industry. With technological advancements, letter bending machines are continuously upgraded, integrating more automated functions to improve production flexibility and processing accuracy.

[0003] However, in real life, bending materials left and right usually requires too much manual operation, which wastes time and reduces efficiency, and also wastes manpower. Therefore, this invention provides a double fixed blade independent motion mechanism for a bending machine. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention discloses a double-fixed-blade independent motion mechanism for a letter bending machine, comprising a mounting bracket, on which a fixed bending blade and a connecting bracket are fixedly mounted, a reducer is fixedly mounted on the connecting bracket, a motor is fixedly mounted on the reducer, the output end of the motor is connected to the input end of the reducer, a coupling is fixedly mounted on the reducer, a drive shaft is fixedly mounted on the coupling, and two symmetrically distributed drive gears are fixedly mounted on the drive shaft. The mechanism also includes a left independent motion component, a right independent motion component, and a braking component for braking the left and right independent motion components.

[0005] Furthermore, the left-side independent motion component includes a driven gear two, which is rotatably mounted on the lower half of the mounting bracket. A left-side cutter bar is fixedly mounted on the driven gear two, and a driven gear one is fixedly mounted on one end of the left-side cutter bar. The driven gear one is provided with a limiting groove two, and both the driven gear two and the driven gear one are provided with missing teeth. The driven gear one meshes with the driving gear one on the upper half of the drive shaft, and the driven gear two meshes with the driving gear one on the lower half of the drive shaft. The two driving gears one drive the driven gear two and the driven gear three to rotate respectively, and the driven gear two and the driven gear three together drive the drive shaft to move, which facilitates the drive shaft to cooperate with the fixed bending knife to perform left-side bending work.

[0006] Furthermore, a cylindrical pin is fixedly installed on the driven gear two, which drives the right independent motion component to move, making it easier to switch between the left and right independent motion components.

[0007] Furthermore, the right-side independent motion component includes a driven gear three, which is rotatably mounted on the upper half of the mounting bracket. The driven gear three is connected to a driven gear one, and a right-side cutter bar is fixedly mounted on the driven gear three. The right-side cutter bar slides within a limiting groove two. A driven gear four is fixedly mounted on one end of the right-side cutter bar, and a limiting groove one is provided on the driven gear four. The driven gear four meshes with a driving gear one on the lower half of the drive shaft, and the driven gear three meshes with a driving gear one on the upper half of the drive shaft. Both the driven gear three and the driven gear four have missing teeth. The driven gear four is connected to the driven gear two. The two driving gears one drive the driven gear three and the driven gear four to rotate respectively. The driven gear three and the driven gear four together drive the right-side cutter bar to move, facilitating the right-side cutter bar to cooperate with the fixed bending knife for right-side bending work.

[0008] Furthermore, the limiting groove is provided with an arc groove that cooperates with the cylindrical pin. Through the cooperation between the cylindrical pin and the arc groove, the arc groove drives the right independent motion component to move through the cylindrical pin.

[0009] Furthermore, the braking assembly includes cylinder one and cylinder two. Cylinder one is fixedly mounted on the lower half of the mounting bracket. A brake block one is fixedly mounted on the cylinder arm of cylinder one. The brake block one is provided with a tooth one that cooperates with the driven gear four. Cylinder two is fixedly mounted on the lower part of the mounting bracket. A brake block two is fixedly mounted on the cylinder arm of cylinder two. The brake block two is provided with a tooth two that cooperates with the driven gear two. When the left independent motion assembly moves, the cylinder arm of cylinder one drives brake block one to contact the driven gear four, preventing the driven gear four from moving. When the right independent motion assembly moves, the cylinder arm of cylinder two drives brake block two to contact the driven gear two, preventing the driven gear two from moving.

[0010] The beneficial effects of this invention compared with the prior art are: (1) This invention is provided with a left independent motion component and a right independent motion component, which realizes independent left and right bending of the board through the left independent motion component and the right independent motion component, reducing production time and improving work efficiency; (2) This invention is provided with a braking component, which ensures that when the left independent motion component and the right independent motion component move respectively, the other independent motion component will not move, thus ensuring the independence of the movement.

The mechanism also includes a left independent motion component, a right independent motion component, and a braking component for braking the left and right independent motion components.

[0022] like Figures 4-6 As shown, the left independent motion component includes a driven gear 2 13, which is rotatably mounted on the lower half of the mounting bracket 1. A left tool bar 10 is fixedly mounted on the driven gear 2 13, and a driven gear 1 9 is fixedly mounted on one end of the left tool bar 10. A limiting groove 24 is provided on the driven gear 1 9. Both the driven gear 2 13 and the driven gear 1 9 are provided with missing teeth. The driven gear 1 9 meshes with the driving gear 1 8 on the upper half of the drive shaft 11, and the driven gear 2 13 meshes with the driving gear 1 8 on the lower half of the drive shaft 11. A cylindrical pin 15 is fixedly mounted on the driven gear 2 13.

[0023] like Figure 2 , Figure 3 , Figure 7 , Figure 8As shown, the right-side independent motion component includes a driven gear 3 16, which is rotatably mounted on the upper half of the mounting bracket 1. The driven gear 3 16 is connected to the driven gear 1 9. A right-side tool bar 17 is fixedly mounted on the driven gear 3 16. The right-side tool bar 17 slides within the limiting groove 24. A driven gear 4 18 is fixedly mounted on one end of the right-side tool bar 17. A limiting groove 19 is provided on the driven gear 4 18. The driven gear 4 18 meshes with the driving gear 1 8 on the lower half of the drive shaft 11. The driven gear 3 16 meshes with the driving gear 1 8 on the upper half of the drive shaft 11. Both the driven gear 3 16 and the driven gear 4 18 have missing teeth. The driven gear 4 18 is connected to the driven gear 2 13. An arc groove 7 that cooperates with the cylindrical pin 15 is provided on the limiting groove 19.

[0024] The braking assembly includes cylinder 20 and cylinder 22. Cylinder 20 is fixedly mounted on the lower half of the mounting bracket 1. A brake block 21 is fixedly mounted on the cylinder arm of cylinder 20. The brake block 21 is provided with a tooth that cooperates with the driven gear 18. Cylinder 22 is fixedly mounted on the lower part of the mounting bracket 1. A brake block 23 is fixedly mounted on the cylinder arm of cylinder 22. The brake block 23 is provided with a tooth that cooperates with the driven gear 13.

[0025] Working principle: When bending is required, the motor 4 starts rotating forward. The output of the motor 4 is adjusted by the reducer 5. The output of the reducer 5 drives the drive shaft 11 to rotate through the coupling 6. The drive shaft 11 drives the two drive gears 1-8 to rotate. When the left-side cutter bar 10 needs to move, the two drive gears 1-8 contact the missing teeth of the driven gears 1-6 and 1-8. The cylinder 20 is activated, and the cylinder arm of the cylinder 20 drives the brake block 21 to move. The brake block 21 meshes with the driven gear 1-8, preventing the driven gear 1-8 from moving. The upper drive gear 8 of the drive shaft 11 drives the driven gear 9 to rotate, while the lower drive gear 8 drives the driven gear 13 to rotate. Driven gears 9 and 13 together drive the left tool holder 10 to move. The left tool holder 10 moves within the limiting groove 19, bending the sheet metal. This causes the motor 4 to reverse, and the left tool holder 10 returns to its original position after bending. When the right tool holder 17 needs to move, the two drive gears 8 continue to drive driven gears 9 and 13. Driven gear 13 moves through a circular... The pin 15 contacts the arc groove 7 in the limiting groove 19. The engagement of the limiting groove 19 and the arc groove 7 drives the driven gear 18 to move, activating cylinder 20 and causing its cylinder arm to retract. This activates cylinder 22, whose cylinder arm drives brake block 23 to mesh with driven gear 13, preventing it from moving. At this time, the two driving gears 18 contact the missing teeth on driven gears 19 and 13. The driving gears 18 on the upper part of the drive shaft 11 drive driven gear 16 to rotate, while the lower part of the drive shaft 11... Part of the driving gear 18 drives the driven gear 4 18 to rotate. The driven gear 3 16 and the driven gear 4 18 together drive the right cutter bar 17 to move. The right cutter bar 17 moves in the limiting groove 24. The right cutter bar 17 bends the plate. After the right independent motion component completes the bending, the motor 4 rotates forward, and the right cutter bar 17 returns to its original position after bending. Then, the right cutter bar 17 drives the driven gear 9 to mesh with the driving gear 8 on the upper part of the drive shaft 11 through the limiting groove 24. This process is repeated to realize the independent bending motion of the left cutter bar 10 and the right cutter bar 17 on the plate.
