Technical Field

[0001] The utility model belongs to the technical field of pipe bending machines, and in particular relates to a pipe bending device for a high-speed railway handrail pipe. Background Art

[0002] In the production and processing of high-speed rail handrail pipes, some pipes often need to be bent. In order to save costs, high-speed rail handrail pipe manufacturers often use semi-automatic pipe bending machines to process pipes. The existing pipe bending machine includes a bending assembly, a support wheel and a guide die. When in use, the staff places the pipe at the designated position of the bending machine, and the control host of the bending machine controls the clamping parts to fix the pipe so that the pipe is clamped between the support wheel and the guide die; at the same time, the control host controls the guide die to rotate along the axis of the support wheel, thereby realizing the bending of the pipe.

[0003] When bending a handrail pipe, both ends of the pipe are usually bent. For example, in the pipe bending machine disclosed in patent CN219724208U, the worker places the pipe on the guide assembly, and the clamping assembly can limit and fix the pipe, and then the pipe is bent. After one end is processed, the worker takes out the pipe and puts the other end in for further processing. However, this bending method cannot achieve the bending and forming of both ends of a handrail pipe at the same time. After one end is bent, the pipe needs to be moved again or the direction needs to be adjusted to bend the other end. The work is cumbersome and greatly wastes labor resources. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a pipe bending device for a high-speed railway handrail pipe, comprising a workbench 1 and a storage bin 2. Bending components are respectively arranged on both sides of the top of the workbench 1. The bending components include a fixed shaft 5, a rotating shaft 6 and a contact plate 8. The rotating shaft 6 can be rotatably arranged at the front end of the workbench 1 with the fixed shaft 5 as the center. The contact plate 8 can be slidably arranged between the two rotating shafts 6 to press the pipe against the front side of the two fixed shafts 5 when moving backward. The storage bin 2 is arranged above the front end of the workbench 1. The inner cavity of the storage bin 2 is bucket-shaped. A discharge trough is opened at the rear end of the bottom of the storage bin 2. A baffle 9 that can block the discharge trough is slidably connected to the bottom of the storage bin 2. When the baffle 9 is removed, the pipe falls to the top of the workbench 1 and is located between the fixed shaft 5 and the rotating shaft 6.

[0020] The fixed shaft 5 can rotate on its axis, and the rotating shaft 6 is driven by a hydraulic system to rotate around the fixed shaft 5, with high output and good stability.

[0021] When the rotating shaft 6 is stationary, a space for placing the pipe is formed between the front end of the fixed shaft 5 and the fixed shaft 5. When the pipe is placed between the rotating shaft 6 and the fixed shaft 5, the rotating shaft 6 rotates around the fixed shaft 5 as the center when sliding, bending the pipe.

[0022] The two sets of bending components on both sides can be configured as structures that can move relative to the workbench 1, and move outward or inward respectively to change the distance between the two sets of bending components, thereby adapting to pipes of different lengths.

[0023] A guide plate inclined downward is provided at the rear end of the baffle 9 to guide the pipe. When the baffle 9 slides toward the front end until the discharge trough is opened to form a channel large enough to accommodate a pipe falling down, a pipe slides out of the discharge trough of the storage bin 2. When the pipe falls, it slowly falls along the guide plate into between the fixed axis 5 and the rotating axis 6 of the bending assembly. At the same time, when the pipe falls, the baffle 9 slides toward the rear end to block the discharge trough, and at the same time, the resistance plate 8 moves backward to press the pipe against the fixed axis 5, and then the rotating axis 6 rotates a certain angle to perform the bending work.

[0024] In this embodiment, the material storage bin 2 is located above the front end of the workbench 1. Because the inner cavity of the material storage bin 2 is in the shape of an inverted slope, and the material storage bin 2 discharge chute is blocked by a baffle 9, the material storage bin 2 can store more pipe materials. When the baffle 9 slides, it slides together with the contact plate 8. When the baffle 9 slides forward, the discharge chute is opened, and the pipe materials in the material storage bin 2 fall. As the pipe materials fall, the baffle 9 slides backward to block the material storage bin 2 discharge chute with the baffle 9. Then, when the pipe materials fall, they are bent by the bending assembly on the workbench 1. The contact plate 8 presses one end of the pipe material against the fixed shaft 5, and the other end is pressed against the contact plate 8. As the rotating shafts 6 at both ends run at the same time, the two ends of the pipe material are bent at the same time, and the bending and forming of a pipe is realized at one time. There is no need to move the pipeline or adjust the direction, which can significantly improve the working speed, reduce labor resources, greatly improve the production speed, and save working hours.

[0025] Furthermore, a plurality of fixing seats 12 are fixedly connected to the left and right ends of the workbench 1 , a limit plate 13 is slidably arranged above the fixing seat 12 , and an electric guide rail for driving the limit plate 13 is arranged at the top of the fixing seat 12 .

[0026] When the limiting plates 13 are in operation, the limiting plates 13 on both sides move inward synchronously to limit the pipe from both ends, so that the pipe is in the middle position, so that the pipe will not tilt or deviate.

[0027] In this embodiment, the fixed seat 12 is fixed at the left and right ends of the workbench 1, and an electric guide rail is set on the top of each fixed seat 12. The electric guide rails on both sides can run synchronously, and the electric guide rails drive the limit plates 12 to slide on both sides of the workbench 1.

[0028] Furthermore, a slide rail 7 is provided at the front side of the top of the workbench 1, a slide seat is slidably connected above the slide rail 7, a resistance plate 8 is fixedly connected to the rear end of the slide seat, and a baffle 9 is fixedly connected to the front end of the top of the slide seat.

[0029] In this embodiment, the slide rail 7 is installed on the front side of the top of the workbench, the sliding seat is detachably installed on the slide rail 7, the contact plate 8 is installed on the front end of the sliding seat, and the baffle plate 9 is installed on the rear side of the top of the sliding seat. The baffle plate 9 and the contact plate 8 slide back and forth simultaneously.

[0030] During loading, the sliding seat drives the contact plate and baffle 9 to move forward. When the baffle 9 slides forward until the discharge chute opens, a pipe falls from the storage bin 2. At this time, the contact plate 8 has moved to a position closer to the rear edge of the rotating shaft 6, so that the dropped pipe can directly fall between the fixed shaft 5 and the rotating shaft 6. Then the sliding seat drives the contact plate and baffle 9 to move backward. The baffle 9 first blocks the discharge chute to prevent the pipe from falling further. Then the limit plates 13 on both sides move inward synchronously to limit the pipe from both ends, so that the pipe is in the middle position. Then the sliding seat continues to move forward at the same time, so that the contact plate 8 presses the pipe against the fixed shaft 5. In this process, the baffle 9 always blocks the discharge chute.

[0031] Furthermore, a cylinder 11 is provided at the front end of the slide rail 7 , and the rear end of the slide seat is fixedly connected to the cylinder 11 .

[0032] In this embodiment, the cylinder 11 is installed at the front end of the workbench and fixedly connected to the rear end of the sliding seat. The sliding seat is pushed by the cylinder 11 to move, thereby driving the resistance plate 8 and the baffle 9 to move synchronously, and at the same time it is convenient to control the sliding distance and time node.

[0033] Furthermore, a rotating groove is provided at the rear end of the workbench 1, a rotating plate 14 is rotatably provided in the rotating groove, and a groove for holding up the pipe is provided at the front end of the rotating plate 14.

[0034] In this embodiment, a rotating groove is provided at the rear end of the workbench 1, and two rotating plates 14 are installed in the rotating groove. The rotating plates 14 can rotate 360 ​​degrees in the rotating groove, and a groove is provided at the front end of the rotating plates 14 to hold up the pipe.

[0035] When the tube is bent, the abutment plate 8 moves slightly forward a certain distance and separates from the tube, while the baffle plate 9 remains in a blocked state. Then the rotating plate 14 rotates upward from the rotating groove, and the bent tube is lifted by the groove and rotated toward the rear of the workbench 1, so that the tube can be taken out and unloaded easily.

[0036] The two rotating plates 14 can be installed on a driving shaft and driven by a motor to rotate synchronously. The two rotating plates 14 cooperate with each other to hold up the pipe at the same time to prevent the pipe from tilting or sliding.

[0037] Furthermore, two conveyor belts 3 are spaced apart at the rear end of the workbench 1 , a plurality of support columns 16 are fixedly connected to the bottom end of the conveyor belts 3 , and a plurality of support legs 4 are fixedly connected to the bottom end of the workbench 1 .

[0038] In this embodiment, the bent pipe material is lifted up by the rotating plate 14 and then rotated until it is rotated above the conveyor belt 3, and then slides onto the conveyor belt 3, with both ends falling on one conveyor belt 3 respectively, and is transported backward by the conveyor belt 3. The rotating plate 14 will continue to rotate and reset from the gap between the two conveyor belts 3 to carry out the next cycle.

[0039] Furthermore, a fixing column 15 is fixedly connected to the bottom end of the storage bin 2 , and the other end of the fixing column 15 is fixedly connected to the top end of the workbench 1 .

[0040] In this embodiment, the storage bin 2 is supported and fixed by two fixing columns 15 , and the two fixing columns 15 are fixedly connected to the workbench 3 , and the two fixing columns 15 do not hinder the bending of the pipe material on the workbench 1 .

[0041] The working principle and use process of the utility model are as follows: after the utility model is installed, the pipe material is placed in the storage bin 2, and then the cylinder 11 retracts to drive the fixed seat 12 to move forward, and the baffle 9 on the fixed seat 12 slides to open the discharge slot blocked by the baffle 9 at the bottom of the storage bin 2, and then the pipe material in the storage bin 2 falls, and the guide plate of the baffle 9 guides the pipe material so that the pipe material falls between the fixed shaft 5 and the rotating shaft 6. When the pipe material falls, the baffle 9 slides to the rear end to block the discharge slot, and the contact plate 8 moves backward to press the pipe material against the fixed shaft 5, and the limit plates 13 on both sides move inward synchronously to limit the pipe material from both ends, so that the pipe material It is in the middle position so that the pipe will not tilt or deviate. Then the rotating shaft 6 rotates a certain angle to perform the bending work. After the pipe is bent into shape, the resistance plate 8 moves slightly forward a certain distance and separates from the pipe. At the same time, the baffle 9 remains in a blocked state. Then the rotating plate 14 rotates upward from the rotating groove, and the bent pipe is lifted by the groove and rotated toward the rear of the workbench 1 until it rotates above the conveyor belt 3, slides onto the conveyor belt 3, and the two ends fall on one conveyor belt 3 respectively, and the conveyor belt 3 transports the material backward. The rotating plate 14 will continue to rotate and reset from the gap between the two conveyor belts 3, and perform the next cycle, thereby realizing the bending of the high-speed railway handrail pipe.
