Description

Technical Field

[0001] This application belongs to the field of steel pipe bending technology, specifically an adaptive steel pipe bending device. Background Technology

[0002] In numerous fields such as machinery manufacturing, automotive industry, and construction, steel pipes of various shapes are required to meet diverse structural and functional requirements. For example, automobile frames and exhaust pipes, as well as scaffolding and stair railings in construction, all require steel pipes to be bent into specific angles and shapes to achieve functions such as component connection, support, or fluid transport. With the expansion of industrial production scale and the increase in product complexity, the requirements for the precision, efficiency, and quality of steel pipe bending are also becoming increasingly stringent, driving the continuous development of steel pipe bending technology.

[0003] Existing steel pipe bending uses a hydraulic system for power, which has a large bending force and can bend large-diameter, thick-walled steel pipes. The bending process is smooth and highly accurate. The basic support structure of the bending machine is welded from high-strength steel plates, which has high strength and rigidity and can withstand the huge pressure generated during the bending process. The worktable is equipped with positioning and clamping devices to ensure the accurate position of the steel pipe during the bending process and prevent it from moving or shaking. The bending die is the component that directly acts on the steel pipe. It consists of an upper die and a lower die. The upper die is usually connected to the piston rod of the hydraulic cylinder, and the lower die is fixed on the worktable.

[0004] However, the following problems still exist: the included angle of the existing bending die is constant. When steel pipes need to be bent at different angles, different molds need to be changed, making it impossible to change the die in a timely manner according to the bending requirements of different steel pipes. This is time-consuming, labor-intensive, and affects work efficiency. Utility Model Content

[0005] The purpose of this application is to provide an adaptive steel pipe bending device in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: An adaptive steel pipe bending device includes a base, a limiting plate fixedly connected to the upper surface of the base, two limiting plates, and a connecting rod rotatably connected to the opposite surfaces of the two limiting plates. A driving plate is fixedly sleeved on the surface of the connecting rod, and a rotating cylinder is rotatably connected to the surface of the connecting rod. A second bending plate is fixedly connected to the end of the rotating cylinder away from the connecting rod. A first bending plate is fixedly connected to the side of the driving plate away from the connecting rod. A U-shaped plate is slidably connected to the opposing surfaces of the first bending plate and the limiting plate. A rotating rod is rotatably connected to the inner wall of the U-shaped plate. A vertical plate is fixedly sleeved on the surface of the rotating rod, and a push plate is fixedly connected to the side of the vertical plate.

[0007] Preferably, a support plate is fixedly connected to the upper surface of the base, an electric push rod is fixedly connected to the upper surface of the support plate, a bending block is fixedly connected to the bottom end of the electric push rod, and a steel pipe is inserted through the front of the support plate. By setting the electric push rod, the steel pipe is placed above the second bending plate through the support plate. The electric push rod moves to push the bending block down to cooperate with the second bending plate and the first bending plate to bend the steel pipe.

[0008] Preferably, a sliding frame is fixedly connected to the upper surface of the base, and the push plate is slidably sleeved on the surface of the sliding frame. By setting the sliding frame, the push plate can slide stably on the upper surface of the base after being pushed.

[0009] Preferably, the lower surfaces of the first and second bending plates are provided with grooves, and a slider is slidably connected to the inner wall of the groove. The side of the slider away from the inner wall of the groove is fixedly connected to the U-shaped plate. The U-shaped plate is slidably connected to the lower surfaces of the first and second bending plates through the slider and the groove respectively. By providing the groove, when the vertical plate is pushed, the slider slides in the groove. At this time, the vertical plate moves on the lower surfaces of the first and second bending plates through the slider and the groove, which facilitates pushing the first and second bending plates to rotate.

[0010] Preferably, a threaded cylinder is fixedly inserted through the front of the push plate, and a bidirectional threaded screw is threadedly connected to the inner wall of the threaded cylinder. When the bidirectional threaded screw rotates clockwise, it drives the two push plates to move toward their respective opposite faces using the threaded cylinder. At this time, the included angle between the second bending plate and the first bending plate becomes smaller. When the bidirectional threaded screw rotates counterclockwise, it drives the two push plates to move toward their respective opposite faces using the threaded cylinder. The angle between the second bending plate and the first bending plate becomes larger.

[0011] Preferably, a rotating disk is fixedly connected to the end of the bidirectional threaded screw away from the support plate. The rotating disk is annular in shape. By setting the rotating disk, it is easy for the user to drive the bidirectional threaded screw to rotate, thereby using the threaded cylinder to push the vertical plate to move.

[0012] Preferably, the lower surface of the base is fixedly connected with four support legs, which are arranged in a rectangular array at the four corners of the lower surface of the base. By setting four support legs, the base can be stably supported.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, rotating the rotating disk drives the bidirectional threaded screw to rotate. The bidirectional threaded screw rotates clockwise, which in turn drives the two push plates to move toward their respective opposite faces via the threaded cylinder. The movement of the push plates drives the vertical plate to move. The movement of the vertical plate pushes the first bending plate and the second bending plate to rotate via the U-shaped plate. The first bending plate and the second bending plate rotate toward their respective opposite faces. At this time, the included angle between the first bending plate and the second bending plate becomes smaller. Reversing the rotation of the rotating disk drives the two push plates to move toward their respective opposite faces via the threaded cylinder. At this time, the included angle between the first bending plate and the second bending plate becomes larger. Rotating the rotating disk drives the bidirectional threaded screw until the included angle between the first bending plate and the second bending plate is adjusted to the required position. The steel pipe is then placed above the second bending plate through the support plate. Then, the electric push rod is turned on. The electric push rod moves and pushes the bending block down to cooperate with the second bending plate and the first bending plate to bend the steel pipe. Thus, the equipment has the effect of facilitating the bending of steel pipes at different angles. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example:

[0022] Reference Figure 2-4An adaptive steel pipe bending device includes a base 1. Two limiting plates 6 are fixedly connected to the upper surface of the base 1. A connecting rod 19 is rotatably connected to the opposite surfaces of the two limiting plates 6. A driving plate 8 is fixedly sleeved on the surface of the connecting rod 19. A rotating cylinder 20 is rotatably connected to the surface of the connecting rod 19. A second bending plate 9 is fixedly connected to the side of the rotating cylinder 20 away from the connecting rod 19. A bidirectional threaded screw 11 rotates clockwise, using the threaded cylinder 12 to drive two push plates 21 to move towards their respective opposite surfaces. The movement of the push plates 21 drives a vertical plate 14 to move. The movement of the vertical plate 14 pushes a first bending plate 7 and a second bending plate 9 to rotate via a U-shaped plate 15. The first bending plate 7 and the second bending plate 9 rotate towards their respective opposite surfaces, at which point the included angle between the first bending plate 7 and the second bending plate 9 decreases.

[0023] Reference Figure 1-2 A first bending plate 7 is fixedly connected to the side of the driving plate 8 away from the connecting rod 19. A U-shaped plate 15 is slidably connected to the opposing surfaces of the first bending plate 7 and the limiting plate 6. A rotating rod 22 is rotatably connected to the inner wall of the U-shaped plate 15. A vertical plate 14 is fixedly sleeved on the surface of the rotating rod 22. A push plate 21 is fixedly connected to the side of the vertical plate 14. The rotating disk 10 is rotated in the opposite direction. The rotation of the rotating disk 10 drives the two push plates 21 to move toward their respective opposing surfaces by using the threaded cylinder 12. At this time, the included angle between the first bending plate 7 and the second bending plate 9 becomes larger. The rotating disk 10 drives the bidirectional threaded screw 11 until the included angle between the first bending plate 7 and the second bending plate 9 is adjusted to the required position.

[0024] Reference Figure 1-3 A support plate 3 is fixedly connected to the upper surface of the base 1. An electric push rod 4 is fixedly connected to the upper surface of the support plate 3. A bending block 5 is fixedly connected to the bottom end of the electric push rod 4. A steel pipe 18 is inserted through the front of the support plate 3. By setting the electric push rod 4, the steel pipe 18 is inserted through the support plate 3 and placed above the second bending plate 9. The electric push rod 4 moves to push the bending block 5 down to cooperate with the second bending plate 9 and the first bending plate 7 to bend the steel pipe 18.

[0025] Reference Figure 2-4 A sliding frame 13 is fixedly connected to the upper surface of the base 1, and the push plate 21 is slidably sleeved on the surface of the sliding frame 13. By setting the sliding frame 13, the push plate 21 can slide stably on the upper surface of the base 1 after being pushed.

[0026] Reference Figure 1-2The lower surfaces of the first bending plate 7 and the second bending plate 9 are both provided with grooves 16. A slider 17 is slidably connected to the inner wall of the groove 16. The side of the slider 17 away from the inner wall of the groove 16 is fixedly connected to the U-shaped plate 15. The U-shaped plate 15 is slidably connected to the lower surfaces of the first bending plate 7 and the second bending plate 9 through the slider 17 and the groove 16 respectively. By providing the groove 16, when the vertical plate 14 is pushed, the slider 17 slides in the groove 16. At this time, the vertical plate 14 moves on the lower surfaces of the first bending plate 7 and the second bending plate 9 through the slider 17 and the groove 16, which facilitates pushing the first bending plate 7 and the second bending plate 9 to rotate. A threaded cylinder 12 is fixedly inserted through the front of the push plate 21. The inner wall of 12 is threaded with a double-threaded screw 11. When the double-threaded screw 11 rotates clockwise, it drives the two push plates 21 to move toward their respective opposite faces using the threaded cylinder 12. At this time, the included angle between the second bending plate 9 and the first bending plate 7 becomes smaller. When the double-threaded screw 11 rotates counterclockwise, it drives the two push plates 21 to move toward their respective opposite faces using the threaded cylinder 12. The angle between the second bending plate 9 and the first bending plate 7 becomes larger. The end of the double-threaded screw 11 away from the support plate 3 is fixedly connected to a rotating disk 10. The rotating disk 10 is ring-shaped. By setting the rotating disk 10, it is easy for the user to drive the double-threaded screw 11 to rotate, thereby using the threaded cylinder 12 to push the vertical plate 14 to move.

[0027] Reference Figure 1-3 The lower surface of the base 1 is fixedly connected with four support legs 2, which are arranged in a rectangular array at the four corners of the lower surface of the base 1. By setting four support legs 2, the base 1 can be stably supported.

[0028] The implementation principle of the adaptive steel pipe bending device embodiment of this application is as follows: Rotating the rotating disk 10 causes the bidirectional threaded screw 11 to rotate. The clockwise rotation of the bidirectional threaded screw 11 uses the threaded cylinder 12 to drive two push plates 21 to move towards their respective opposite faces. The movement of the push plates 21 drives the vertical plate 14 to move. The movement of the vertical plate 14 pushes the first bending plate 7 and the second bending plate 9 to rotate via the U-shaped plate 15. The first bending plate 7 and the second bending plate 9 rotate towards their respective opposite faces. At this time, the included angle between the first bending plate 7 and the second bending plate 9 becomes smaller. Rotating the rotating disk 10 in the opposite direction... The rotating disc 10 drives the threaded cylinder 12 to move the two push plates 21 toward their respective opposing faces. At this time, the included angle between the first bending plate 7 and the second bending plate 9 increases. The rotating disc 10 drives the bidirectional threaded screw 11 until the included angle between the first bending plate 7 and the second bending plate 9 is adjusted to the required position. The steel pipe 18 is then placed above the second bending plate 9 through the support plate 3. Then the electric push rod 4 is turned on. The electric push rod 4 moves and pushes the bending block 5 down to cooperate with the second bending plate 9 and the first bending plate 7 to bend the steel pipe 18, so that the equipment can easily bend steel pipes at different angles.
