Description

Technical Field

[0001] This utility model relates to the field of high-frequency welded pipe bending and forming technology, and in particular to a multi-angle bending and forming equipment for high-frequency welded pipes. Background Technology

[0002] High-frequency welded pipe is a type of steel pipe produced through high-frequency welding technology. It is characterized by high efficiency and economy and is widely used in construction, transportation, machinery manufacturing and other fields. High-frequency welded pipe uses the heat generated by high-frequency current to heat the edges of the steel pipe to a melting state, and then they are joined together under pressure to form a weld. During the production of high-frequency welded pipe, bending processing can improve the mechanical properties of the pipe, making it more suitable for specific application requirements.

[0003] An existing metal pipe bending device (publication number: CN221493788U) can quickly place multiple metal pipes through multiple sets of corresponding semi-circular placement slots, while also restricting them, and then use a bending mechanism to perform uniform bending processing. However, when placing pipes with different diameters through semi-circular placement slots and pressure seats, swaying and displacement are prone to occur during placement, affecting the stability of the pipe bending process. Furthermore, the bending angle of the pipe is still limited by only rotating the pressure roller along the fan-shaped through groove to the right, making it difficult to use flexibly according to different needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-angle bending and forming device for high-frequency welded pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-angle bending and forming device for high-frequency welded pipes includes a worktable and a fixed frame. A first sliding groove is formed on the worktable, and a first support frame is movably mounted on the first sliding groove. An electric push rod is fixed to the inner wall of the first support frame, and a horizontal plate is fixed to the output shaft of the electric push rod. A pressure block is fixed to the lower end of the horizontal plate. A placement groove is formed on the first support frame. A second sliding groove is formed on the side of the worktable away from the first sliding groove, and a second support frame is movably mounted on the second sliding groove. A cylinder is fixed to the top of the fixed frame, and a top plate is fixed to the output shaft of the cylinder. A lower pressure roller is fixed to the bottom of the top plate, and a pressure groove is formed below the lower pressure roller. A recessed opening is formed on one side of the pressure groove, and an arc-shaped plate is fixed inside the recessed opening. A movable roller is movably mounted on the arc-shaped plate.

[0007] As a further embodiment of this utility model, the placement slots are evenly distributed on the support frame one, and a hydraulic rod one is fixedly provided on the side of the worktable surface near the slide groove one. The output shaft of the hydraulic rod one is fixedly connected to the bottom of the support frame one, and the support frame one is slidably connected to the slide groove one.

[0008] As a further embodiment of this utility model, the pressure blocks are evenly distributed on the horizontal plate, and rubber pads are fixedly installed on the pressure blocks. A hydraulic rod two is fixedly provided on the side of the worktable away from the hydraulic rod one, and the hydraulic rod two is fixedly connected to the bracket two through an output shaft.

[0009] As a further embodiment of this utility model, the second bracket is slidably connected to the second slide groove, and a motor is provided on one side of the arc plate by fasteners. A rotating rod is fixed on the output shaft of the motor, and the rotating rod is movably connected to the arc plate.

[0010] As a further embodiment of this utility model, a guide groove is provided on the arc-shaped plate, a connecting rod is movably arranged in the guide groove, the movable roller is fixedly connected to the connecting rod, the bottom end of the connecting rod is fixedly connected to the rotating rod, and an angle scale plate is fixedly provided on the side of the arc-shaped plate away from the motor.

[0011] As a further embodiment of this utility model, the guide groove and the connecting rod are symmetrically distributed on the arc plate, an angle sensor is fixedly provided on the outer wall of the connecting rod, and a control panel is fixedly installed on the worktable.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In use, pressure blocks, horizontal plates, placement grooves, rubber pads, and electric push rods are installed on both support frame one and support frame two. One end of multiple sets of high-frequency welded pipes is placed into the corresponding placement groove on support frame one, while the other end is placed on support frame two. Then, the operator simultaneously activates two sets of electric push rods via the control panel on one side, pushing the two sets of horizontal plates to move the multiple sets of pressure blocks downwards, effectively fixing both ends of the pipes and ensuring stability during bending. Then, two sets of hydraulic rods are activated to further adjust the positions of support frame one and support frame two, further moving and conveying the pipes to facilitate multi-segment bending. Depending on processing needs, the electric push rods can be activated... The machine uses a motor to drive a rotating rod on an arc-shaped plate via its output shaft. The rotating rod then drives two sets of connecting rods to rotate along corresponding guide grooves. This, in turn, causes the movable roller to rotate, bending the pipe at multiple angles. An angle sensor and an angle scale plate monitor the rotation angle of the movable roller, allowing operators to control and adjust the bending angle of the pipe. Simultaneously, a cylinder is activated, causing it to push a top plate downwards via its output shaft. The top plate then moves a lower pressure roller closer to the pipe. With the help of the pressure groove, the lower pressure roller again bends the pipe at a vertical angle, allowing for flexible use according to different needs and improving the efficiency of multi-angle bending and forming of the pipe.

[0022] Reference Figures 1-4 A multi-angle bending and forming device for high-frequency welded pipes includes a worktable 1 and a fixed frame 3. A slide groove 201 is formed on the worktable 1, and a support frame 2 is movably mounted on the slide groove 201. An electric push rod 203 is fixed to the inner wall of the support frame 2, and a horizontal plate 5 is fixed to the output shaft of the electric push rod 203. A pressure block 8 is fixed to the lower end of the horizontal plate 5. A placement groove 802 is formed on the support frame 2. A [missing information - likely a design feature] is formed on the side of the worktable 1 away from the slide groove 201. The slide chute 303 has a bracket 806 movably mounted on it. The top of the fixed bracket 3 is fixedly equipped with a cylinder 301. The output shaft of the cylinder 301 is fixedly equipped with a top plate 803. The bottom of the top plate 803 is fixedly equipped with a lower pressure roller 103. The lower pressure roller 103 is provided with a pressure groove 101 below it. The side of the pressure groove 101 is provided with a groove opening 102. An arc-shaped plate 105 is fixedly installed in the groove opening 102. A movable roller 104 is movably mounted on the arc-shaped plate 105.

[0023] In use, one end of each set of high-frequency welded pipes is placed into the respective placement slots 802 on the support frame 1 2. Both the support frame 1 2 and the support 2 806 are equipped with pressure blocks 8, horizontal plates 5, placement slots 802, rubber pads 801, and electric push rods 203. This places the other end of each set of pipes on the support 2 806. Then, the two sets of electric push rods 203 are simultaneously activated, causing the two sets of horizontal plates 5 to move the pressure blocks 8 downwards, effectively fixing both ends of the pipes. Then, the two sets of hydraulic rods 202 are activated to further adjust the positions of the support frame 1 2 and the support 2 806, moving and conveying the fixed pipes above, enabling multi-segment bending of the pipes. The process begins with starting the motor 302, which drives the rotating rod 7 to rotate. This, in turn, causes the two sets of connecting rods 805 to rotate along their respective guide grooves 106. The rotating roller 104 then bends the tube at multiple angles. With the cooperation of the angle sensor 804 and the angle scale plate 6, the bending angle of the rotating roller 104 is monitored. The starting cylinder 301 pushes the top plate 803 downward, which in turn moves the lower pressure roller 103 downward to contact the tube. Under the action of the pressure groove 101, the lower pressure roller 103 performs a vertical bending process on the tube. This allows for flexible use according to different needs and improves bending efficiency.

[0024] In this embodiment, the placement slots 802 are evenly distributed on the support frame 2. A hydraulic rod 202 is fixedly provided on the side of the worktable 1 near the slide groove 201.

[0025] In use, the upper end of the pipe is fixed by the pressure block 8. Under the action of the rubber gasket 801, the friction between the pressure block 8 and the surface of the pipe is increased, thereby preventing loosening and improving the stability of the pipe clamping.

[0026] In this embodiment, the pressure blocks 8 are evenly distributed on the horizontal plate 5, and rubber pads 801 are fixedly installed on the pressure blocks 8. A hydraulic rod 807 is fixedly installed on the side of the worktable 1 away from the hydraulic rod 202. The hydraulic rod 807 is fixedly connected to the bracket 806 through the output shaft.

[0027] In use, hydraulic rod 202 is activated to push support frame 2 to slide back and forth along slide groove 201, and hydraulic rod 807 is used to push support 806 to slide along slide groove 303. With the cooperation of support frame 2 and support 806, the two ends of the pipe are fixed and the pipe is transported and bent at the same time.

[0028] In this embodiment, bracket 2 806 is slidably connected to slide groove 2 303, and a motor 302 is provided on one side of arc plate 105 by fasteners. A rotating rod 7 is fixed on the output shaft of motor 302, and the rotating rod 7 is movably connected to arc plate 105.

[0029] In use, multiple sets of pressure blocks 8 and placement grooves 802 are provided on both the first bracket 2 and the second bracket 806. The multiple sets of placement grooves 802 are "V" shaped to effectively limit the pipe and prevent the pipe from rolling during transportation.

[0030] In this embodiment, a guide groove 106 is provided on the arc plate 105, and a connecting rod 805 is movably provided in the guide groove 106. The movable roller 104 is fixedly connected to the connecting rod 805, and the bottom end of the connecting rod 805 is fixedly connected to the rotating rod 7. An angle scale plate 6 is fixedly provided on the side of the arc plate 105 away from the motor 302.

[0031] In use, the guide groove 106 is provided in two sets on the arc plate 105, and the two sets of guide grooves 106 are arc-shaped. The angle scale plate 6 makes it easier for the staff to see the rotation angle of the movable roller 104 more intuitively.

[0032] In this embodiment, the guide groove 106 and the connecting rod 805 are symmetrically distributed on the arc plate 105, the outer wall of the connecting rod 805 is fixedly provided with an angle sensor 804, and the control panel 4 is fixedly installed on the worktable 1.

[0033] During use, the rotation angle of the movable roller 104 is continuously monitored by the angle sensor 804, and the data is transmitted to the control panel 4 so that the staff can record the data.

[0034] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When preparing for the bending and forming of high-frequency welded pipes, the worker places one end of multiple sets of high-frequency welded pipes into the corresponding placement slot 802 on the support frame 1 2, and the other end is placed on the support 2 806. Then, the worker operates the control panel 4 on one side to simultaneously start two sets of electric push rods 203, which push two sets of horizontal plates 5 to move multiple sets of pressure blocks 8 downwards, thereby effectively fixing both ends of the pipe and ensuring the stability of the pipe during bending. Then, the worker starts two sets of hydraulic rods 202 to further adjust the position of the support frame 1 2 and the support 2 806, and further moves and transports the pipe to facilitate multi-segment bending of the pipe. According to the processing needs, the motor 3 is started. 02. The motor 302 drives the rotating rod 7 to rotate on the arc plate 105 through the output shaft. The rotating rod 7 drives the two sets of connecting rods 805 to rotate along the corresponding guide grooves 106. Then, the movable roller 104 rotates to bend the pipe at multiple angles. The angle sensor 804 and the angle scale plate 6 are used to monitor the rotation angle of the movable roller 104 so that the operator can control and adjust the bending angle of the pipe. At the same time, the cylinder 301 is activated so that the cylinder 301 pushes the top plate 803 down through the output shaft. The top plate 803 drives the lower pressure roller 103 to move down and approach the pipe. With the cooperation of the pressure groove 101, the lower pressure roller 103 bends the pipe at a vertical angle again so as to flexibly bend according to different forming requirements.
