Description

Technical Field

[0001] This utility model relates to the field of steel pipe beveling technology, and more specifically, to a multi-station automatic steel pipe end beveling and beveling machine. Background Technology

[0002] Due to its excellent corrosion resistance, high compressive strength, high temperature resistance, and impact resistance, thick-walled 304 stainless steel pipes are commonly used in petrochemicals, machinery manufacturing, and production line components. However, when arc welding thick-walled steel pipes, the penetration depth of a single weld is limited, making it impossible to fully penetrate the entire thickness of the plate. Therefore, to ensure the arc reaches the root of the weld, achieving root penetration and a better weld, and to facilitate slag removal, a bevel must be cut at the joint.

[0003] A search revealed that patent publication number CN219310777U discloses a double-head batch beveling device for steel pipes. The device includes a main support frame, with electric push rods and motors on both sides. A movable support frame is fixed externally to the motors. The head of the electric push rod is connected to the tail end of the movable support frame. A cutter head seat is located at the head of the motor. A support block is located in the middle of the main support frame, with a clamping head and a clamping cylinder above the support block. A material support frame is located at the rear of the main support frame, with a feeding cylinder and a feeding mechanism below the material support frame. The feeding mechanism includes a feeding slide and a feeding push block. Material feeding is achieved through gravity and a unique feeding mechanism, enabling automated beveling processing with high efficiency and simple operation (requiring only manual loading). The structure is stable and compact, producing good processing results and facilitating unloading. Subsequent maintenance is also simple, and the device has a certain degree of versatility, enabling beveling and chamfering of bars or pipes. During the development of this utility model, the inventors discovered the following problems with the existing technology:

[0004] When the device beveles and chamfers the ends of the steel pipe, it generates a lot of processing debris. During long-term processing, the accumulation of processing debris will contaminate the workbench and working environment. In addition, if manual cleaning is required, it will increase the workload of the staff.

[0005] Therefore, a multi-station automatic chamfering and beveling machine for steel pipe ends is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] As attached Figures 1 to 5The multi-station automatic chamfering and beveling machine for steel pipe ends shown includes a support 1, a base 2 at the top of the support 1, a processing table 3 on the upper surface of the base 2, a rotating shaft 4 fixedly connected to one end of the processing table 3, the two ends of the rotating shaft 4 being rotatably connected to the base 2, a first helical gear 5 fixedly connected to one end of the rotating shaft 4, a second helical gear 6 meshing with the first helical gear 5 on the side wall of the base 2, and a servo motor driving the second helical gear 6 installed on the base 2, two connecting seats 9 symmetrically arranged on the bottom wall of the processing table 3, a threaded rod 10 rotatably connected between the two connecting seats 9, a slider 11 threadedly sleeved on the outer side of the threaded rod 10, a connecting plate 12 fixedly connected to the slider 11, a blower head 13 installed on the connecting plate 12, a fan 15 bolted to the support 1, a connecting hose 14 connecting the output end of the fan 15 and the rear end of the blower head 13, a guide table 7 fixedly connected to the base 2, and a collection frame 8 located on one side of the support 1 and below the guide table 7.

[0023] In operation, the device first drives the second helical gear 6 to rotate via a servo motor. Then, the rotating second helical gear 6 meshes with the first helical gear 5, causing the first helical gear 5 to drive the rotating shaft 4 to rotate. The rotating shaft 4 then drives the processing table 3 to rotate. By adjusting the rotation of the processing table 3, the processing debris accumulated on the processing table 3 falls along the guide table 7 into the collection frame 8 for collection. Simultaneously, the threaded rod 10 and the slider 11 work together to move the connecting plate 12 and the blower 13 mounted on the connecting plate 12. The moving blower 13, in conjunction with the connecting hose 14 and the blower 15, can blow off some small debris accumulated on the surface of the processing table 3, thereby further improving the cleaning effect of processing debris on the surface of the processing table 3. Example 2

[0024] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0025] In a preferred embodiment, two first electric push rods 16 are symmetrically installed on the processing table 3. Each of the two first electric push rods 16 has a drive motor 17 installed at its output end, and a tool holder 18 is connected to the output end of the drive motor 17. A cutter head 19 is bolted to the tool holder 18. Furthermore, when beveling both ends of the steel pipe, the first electric push rods 16 can push the drive motor 17 and the tool holder 18 and cutter head 19 installed on the drive motor 17 toward one end of the steel pipe. Then, the drive motor 17 drives the cutter head 19 to rotate, and the rotating cutter head 19 performs beveling on the end of the steel pipe.

[0026] In a preferred embodiment, a connecting frame 21 is installed on the upper surface of the bracket 1. Two support blocks 20 are then installed on the upper surface of the bracket 1, below the connecting frame 21. A second electric push rod 22 is installed at the top of the connecting frame 21, and a clamping head 23 is connected to the output end of the second electric push rod 22. Two guide blocks 24 are welded to the upper surface of the bracket 1, on one side of the two support blocks 20. An arc-shaped stop block 25 is rotatably connected to each guide block 24. A spring 26 is connected to each guide block 24, with one end connected to the guide block 24 and the other end connected to the arc-shaped stop block 25. A feeding trough seat 29 is installed on the upper surface of the bracket 1, directly above the two guide blocks 24. A rotating seat 27 is rotatably connected between the two guide blocks 24. A push block 28 is fixedly connected to the outside of the rotating seat 27, and a servo motor for adjusting the rotation of the rotating seat 27 is bolted to the guide block 24. Furthermore, when the device is in use, the rotating seat 27 can be driven by the servo motor first, and then the rotating seat 27 drives the push block 28 to rotate. Finally, the rotating push block 28 moves the steel pipe. At this time, the steel pipe first squeezes the spring 26 through the arc-shaped stop 25, releasing the limit of the steel pipe of the arc-shaped stop 25. Then, the moved steel pipe moves to the support block 20 through the guide block 24. The support block 20 is provided with a limiting groove for placing the steel pipe. Then, the second electric push rod 22 drives the clamping head 23 to move down, and the moving clamping head 23 clamps and fixes the steel pipe placed on the support block 20.

[0027] The working process of this utility model is as follows: First, the steel pipe is placed into the feeding trough seat 29. Then, the rotating seat 27 drives the pushing block 28 to rotate. Finally, the rotating pushing block 28 moves the steel pipe. At this time, the steel pipe first squeezes the spring 26 through the arc-shaped stop 25, releasing the steel pipe limit of the arc-shaped stop 25. Then, the moved steel pipe moves to the support block 20 through the guide block 24. The support block 20 is provided with a limiting groove for placing the steel pipe. Then, the second electric push rod 22 drives the clamping head 23 to move down. The lowered clamping head 23 clamps and fixes the steel pipe placed on the support block 20. Then, the first electric push rod 16 pushes the drive motor 17 and the cutter seat 18 and cutter head 19 provided on the drive motor 17 to move closer to one end of the steel pipe. Then, the drive motor 17 drives the cutter head 19 to rotate. The rotating cutter head 19 performs beveling on the end of the steel pipe.

[0028] When it is necessary to clean the processing debris accumulated on the upper surface of the processing table 3, the second helical gear 6 is first driven to rotate by the servo motor. Then, the rotating second helical gear 6 meshes with the first helical gear 5, which in turn drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the processing table 3 to rotate. By adjusting the rotation of the processing table 3, the processing debris accumulated on the processing table 3 falls along the guide table 7 into the collection frame 8 for collection. At the same time, the threaded rod 10 and the slider 11 are coordinated to move the connecting plate 12 and the blower 13 set on the connecting plate 12. By cooperating with the moving blower 13, the connecting hose 14, and the blower 15, some small debris accumulated on the upper surface of the processing table 3 can be blown off, thereby further improving the cleaning effect of the processing debris on the upper surface of the processing table 3. The above is the working principle of the multi-station automatic chamfering and beveling machine for steel pipe ends.
