Description

Technical Field

[0001] This utility model relates to the technical field of bending machines for spring production, specifically a bending machine for spring production. Background Technology

[0002] Springs are a type of elastic element widely used in the mechanical and electronic industries. When a spring is loaded, it will undergo elastic deformation, converting mechanical work or kinetic energy into deformation energy through elastic deformation. After unloading, the elastic deformation of the spring disappears and it returns to its original shape, converting the previously stored deformation energy into mechanical work or kinetic energy. However, existing devices still have some shortcomings; for example,

[0003] For example, a bending machine for spring production, as described in announcement number CN220426438U, involves starting a first motor to rotate a lead screw. The rotation of the lead screw causes a slider to move up and down on the outer surface of the lead screw, which in turn moves an adjusting column up and down on the outer surface of a rotating plate. This allows adjustment of the distance between the fixed column and the adjusting column, thus adjusting the bending angle of the spring. Then, starting a second motor causes its output shaft to rotate the rotating plate, which in turn rotates the adjusting column on the outer surface of a support plate, allowing adjustment of the column's position. This facilitates bending the spring according to its bending requirements. However, this device has some problems. While it can be used effectively to bend springs, conventional bending machines require bending different types of springs, making it difficult to achieve the desired efficiency. Therefore, we propose a bending machine device for spring production to address these issues. Utility Model Content

The inside of the turntable 8 is fixedly connected to the second motor 9, and the second motor 9 is connected to the third gear 10. The third gear 10 meshes with the rack 11, the rack 11 is slidably connected to the inside of the turntable 8, the rack 11 is symmetrically arranged about the center of the third gear 10, and each rack 11 is connected to a moving plate 12.

The top of the moving plate 12 is fixedly connected to the moving rod 13.

[0020] When in use, after placing the spring steel for spring production on the feeding rack 7, the second motor 9 is started to drive the third gear 10 to rotate according to the different models of springs to be produced. Since the third gear 10 and the rack 11 are meshed, the racks 11 on both sides slide inside the turntable 8, causing the racks 11 to drive the moving plate 12 to slide inside the turntable 8. At the same time, the moving plate 12 drives the moving rod 13 above to move. At this time, the first motor 2 drives the first gear 3 to rotate. Since the first gear 3 and the second gear 4 are meshed, the second gear 4 drives the first rotating rod 5 to rotate. At the same time, the first rotating rod 5 drives the turntable 8 above to rotate, so that the moving rods 13 on both sides of the surface of the turntable 8 rotate synchronously, causing the spring steel to bend.

[0021] A fixing mechanism is provided on the top of the machine body 1. The fixing mechanism includes a push rod 15, an adjusting plate 16, a fixing block 17, and a slide rod 18. The push rod 15 is fixedly connected to the inside of the machine body 1, and the top of the push rod 15 is fixedly connected to the adjusting plate 16. The adjusting plate 16 is slidably connected to the fixing block 17, and the fixing block 17 is slidably connected to the slide rod 18. The slide rod 18 is fixedly connected to the inside of the machine body 1. A cutting mechanism is provided on the top of the machine body 1.

The front end of the moving block 22 is connected to the cutting blade 23.

[0022] One end of the spring steel is moved by the push rod 15 to drive the adjusting plate 16. At this time, the adjusting plate 16 drives the fixing block 17 to slide above the slide rod 18. The fixing blocks 17 on both sides fix one end of the spring steel. At the same time, the fourth motor is started to drive the square second rotating rod 24 to rotate. At the same time, the second rotating rod 24 drives the threaded rod 25 to rotate. At this time, the threaded rod 25 drives the upper feeding rack 7 to adjust its height, so that the spring production effect is better. At the same time, the feeding rack 7 drives the support rod 6 to slide inside the machine body 1, so that the height adjustment of the feeding rack 7 is more stable, and the spring production is completed. After production, the third motor 19 is started to drive the lead screw 20 to rotate, so that the sliders 21 on both sides of the lead screw 20 move synchronously. At this time, the sliders 21 drive the upper moving block 22 to move, so that the cutting blades 23 on the surface of the moving block 22 come closer to each other and cut the spring steel. After the spring is produced, it is removed.

[0023] Working Principle: When using the bending machine for spring production, after placing the spring steel for spring production on the feeding rack 7, the second motor 9 is started to drive the third gear 10 to rotate, depending on the different models of springs to be produced. Since the third gear 10 meshes with the rack 11, the racks 11 on both sides slide inside the turntable 8, causing the racks 11 to drive the moving plate 12 to slide inside the turntable 8. Simultaneously, the moving plate 12 drives the upper moving rod 13 to move, moving one end of the spring steel through the push rod 15 to move the adjusting plate 16. At this time, the adjusting plate 16 drives the fixing block 17 to slide above the slide rod 18, fixing one end of the spring steel with the fixing blocks 17 on both sides. Then, the first motor 2 drives the first gear 3 to rotate. Since the first gear 3 meshes with the second gear 4, the second gear 4 drives the first rotating rod 5 to rotate, simultaneously causing the upper turntable 8 to rotate. The moving rods 13 on both sides of the turntable 8 rotate synchronously, causing the spring steel to bend. At the same time, the fourth motor is started to drive the square second rotating rod 24 to rotate. Simultaneously, the second rotating rod 24 drives the threaded rod 25 to rotate. At this time, the threaded rod 25 drives the upper feeding rack 7 to adjust its height, resulting in better spring production. At the same time, the feeding rack 7 drives the support rod 6 to slide inside the machine body 1, making the height adjustment of the feeding rack 7 more stable, thus completing the spring production. After production, the third motor 19 is started to drive the lead screw 20 to rotate, causing the sliders 21 on both sides of the lead screw 20 to move synchronously. At this time, the sliders 21 drive the upper moving block 22 to move, causing the cutting blades 23 on the surface of the moving block 22 to come closer to each other and cut the spring steel. After the spring is produced, it is removed, thus completing a series of operations.
