Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, specifically to a pipe bending machine clamping device. Background Technology

[0002] In modern industrial production, pipe bending machines are widely used for bending various types of pipes. The clamping device of the pipe bending machine is an important component, and its performance directly affects the quality and efficiency of pipe bending. Traditional pipe bending machine clamping devices have some shortcomings in practical applications. On the one hand, the clamping force of some clamping devices is not stable enough, and the pipe may slip during the bending process, thus affecting the accuracy and quality of the bending. This problem is more prominent when processing pipes with high hardness or smooth surfaces. On the other hand, some clamping devices have poor adaptability and can only be used for pipes of specific specifications. For pipes of different diameters and materials, it is necessary to frequently change the clamping device, which not only increases the complexity of operation but also reduces production efficiency.

[0003] Pipe bending requires the use of a pipe bending machine. Most existing pipe bending machines have non-adjustable clamping devices that are only suitable for pipes of specific sizes. They cannot effectively clamp pipes of different diameters, which greatly limits the application range of the pipe bending machine. When processing pipes of various specifications, multiple different clamping devices are required, which increases equipment costs and storage space and reduces the efficiency of the clamping devices.

[0004] Therefore, the clamping device needs to be redesigned and modified to effectively prevent it from being unable to clamp pipes of various sizes. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a clamping device for a pipe bending machine, which has the advantage of high-efficiency clamping. This solves the problem that most existing clamping devices for pipe bending machines are not adjustable and can only be used for pipes of specific sizes. They cannot effectively clamp pipes of different diameters, which greatly limits the application range of the pipe bending machine. When processing pipes of various specifications, multiple different clamping devices are required, which increases equipment costs and storage space and reduces the efficiency of the clamping devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe bending machine clamping device, including a processing table, a motor 1 fixedly connected to the right side of the processing table, the output end of the motor 1 penetrating to the inner side of the processing table, a screw 1 fixedly connected to the output end of the motor 1, a moving plate threadedly connected to the surface of the screw 1, a motor 2 fixedly connected to the top of the moving plate, a fixed gripper fixedly connected to the output end of the motor 2, fixed plates fixedly connected to the top and bottom of the left side of the processing table, a clamping mechanism provided on the left side of the processing table, and a pressing mechanism provided on the top of the processing table.

[0007] In a preferred embodiment of this utility model, the clamping mechanism includes a third motor, the top of which is fixedly connected to the bottom of the bottom fixing plate. A rotating column is fixedly connected to the output end of the third motor, and a mounting bracket is fixedly connected to the surface of the rotating column. An electric cylinder is fixedly connected to the top of the mounting bracket. A lower clamping block is fixedly connected to both the output end of the electric cylinder and the top of the rotating column. An upper clamping block is movably connected to the top of the lower clamping block. A spring is fixedly connected to the top of the inner wall of the upper clamping block, and the bottom of the spring is fixedly connected to the bottom of the inner wall of the lower clamping block.

[0008] In a preferred embodiment of this utility model, the clamping mechanism includes a slide block, a second screw is movably connected to the inner wall of the slide block, a clamping block is threadedly connected to the surface of the second screw, the front side of the second screw extends through to the front side of the slide block, a linkage block is fixedly connected to the front side of the second screw, a belt is rotatably connected to the surface of the linkage block, a drive block is rotatably connected to the side of the belt away from the linkage block, a fourth motor is fixedly connected to the rear side of the drive block, and the front side of the fourth motor is fixedly connected to the surface of the processing table.

[0009] As a preferred embodiment of this invention, a slider is fixedly connected to the bottom of the lower clamping block on the front side, and the slider is slidably connected to the top of the mounting bracket.

[0010] As a preferred embodiment of this utility model, the output end of the electric cylinder is fixedly connected to a reinforcing rib, and the rear side of the reinforcing rib is fixedly connected to the front side of the lower clamping block.

[0011] As a preferred embodiment of this invention, the inner wall of the movable plate is movably connected to a sliding rod, and both sides of the sliding rod are fixedly connected to the inner wall of the processing table.

[0012] As a preferred embodiment of this utility model, limit strips are fixedly connected to both sides of the outer side of the upper clamping block, and the limit strips are movably connected to the lower clamping block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves clamping the pipe fitting onto the left side of a fixed gripper. Starting motor two causes the fixed gripper to clamp the pipe fitting. Then, starting motor one moves the pipe fitting to a suitable position via screw one. Next, starting the electric cylinder moves the lower front clamping block to the rear, which in turn moves the upper front clamping block to the rear. Upon contact with the pipe fitting surface, the pipe fitting presses against the upper clamping block, causing it to move upwards. This upward movement of the upper clamping block causes the spring to move upwards. The force pulls the upper clamping block in the opposite direction to clamp the pipe fitting. After the upper and lower clamping blocks fix the pipe fitting, the motor four is started. The motor four drives the drive block to rotate, the drive block drives the belt to rotate, the belt drives the linkage block to rotate, the linkage block drives the screw two to rotate, and the screw two drives the pressing block to move backward to press against the pipe fitting. At this time, the pipe fitting can be bent. It has the advantage of efficient clamping. The clamping mechanism can clamp pipe fittings of various sizes. The clamping mechanism does not require frequent changes of clamps, which effectively improves the efficiency of the clamping device.

[0015] 2. By setting a clamping mechanism, this utility model can clamp the pipe fitting, preventing other parts of the pipe fitting from bending together during the bending process, thus limiting the clamping position of the clamping device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figures 1 to 5 As shown, the present invention provides a pipe bending machine clamping device, including a processing table 1. A motor 2 is fixedly connected to the right side of the processing table 1. The output end of the motor 2 extends through to the inside of the processing table 1. A screw 3 is fixedly connected to the output end of the motor 2. A moving plate 4 is threadedly connected to the surface of the screw 3. A motor 5 is fixedly connected to the top of the moving plate 4. A fixed gripper 6 is fixedly connected to the output end of the motor 5. Fixed plates 7 are fixedly connected to the top and bottom of the left side of the processing table 1. A clamping mechanism 8 is provided on the left side of the processing table 1. A pressing mechanism 9 is provided on the top of the processing table 1.

[0024] refer to Figure 5 The clamping mechanism 8 includes a motor 81, the top of which is fixedly connected to the bottom of the bottom fixing plate 7. A rotating column 82 is fixedly connected to the output end of the motor 81. A mounting bracket 83 is fixedly connected to the surface of the rotating column 82. An electric cylinder 84 is fixedly connected to the top of the mounting bracket 83. A lower clamping block 85 is fixedly connected to both the output end of the electric cylinder 84 and the top of the rotating column 82. An upper clamping block 86 is movably connected to the top of the lower clamping block 85. A spring 87 is fixedly connected to the top of the inner wall of the upper clamping block 86. The bottom of the spring 87 is fixedly connected to the bottom of the inner wall of the lower clamping block 85.

[0025] As a technical optimization of this utility model, by setting the clamping mechanism 8, it is possible to clamp pipes of various sizes, avoiding the fact that the clamping block can only be used for one type of pipe, which would cause the clamping device to frequently change the clamping block when clamping different pipes, thus improving the ease of use of the clamping device.

[0026] refer to Figure 4 The clamping mechanism 9 includes a slide 91, a screw 92 is movably connected to the inner wall of the slide 91, a clamping block 93 is threadedly connected to the surface of the screw 92, the front side of the screw 92 extends to the front side of the slide 91, a linkage block 94 is fixedly connected to the front side of the screw 92, a belt 95 is rotatably connected to the surface of the linkage block 94, a drive block 96 is rotatably connected to the side of the belt 95 away from the linkage block 94, a motor 97 is fixedly connected to the rear side of the drive block 96, and the front side of the motor 97 is fixedly connected to the surface of the processing table 1.

[0027] As a technical optimization of this utility model, by setting the clamping mechanism 9, the pipe can be clamped, avoiding the pipe from bending along with other parts due to the lack of restraint during the bending process, thus limiting the clamping position of the clamping device.

[0028] refer to Figure 5 A slider 10 is fixedly connected to the bottom of the front lower clamping block 85, and the slider 10 is slidably connected to the top of the mounting bracket 83.

[0029] As a technical optimization of this utility model, by setting the slider 10, the front lower clamping block 85 can be limited, avoiding the front lower clamping block 85 from shaking during movement, which would make it difficult for the front lower clamping block 85 to be clamped with the pipe fitting, thus improving the stability of the front lower clamping block 85 in use.

[0030] refer to Figure 3 The output end of the electric cylinder 84 is fixedly connected to a reinforcing rib 11, and the rear side of the reinforcing rib 11 is fixedly connected to the front side of the lower clamping block 85.

[0031] As a technical optimization of this utility model, by setting the reinforcing rib 11, the front lower clamping block 85 can be reinforced, preventing the front lower clamping block 85 from shaking after long-term use, which would cause the front lower clamping block 85 to disengage from the electric cylinder 84, thereby improving the stability of the front lower clamping block 85 in use.

[0032] refer to Figure 1 The inner wall of the movable plate 4 is movably connected to a slide rod 12, and both sides of the slide rod 12 are fixedly connected to the inner wall of the processing table 1.

[0033] As a technical optimization of this utility model, by setting the slide bar 12, the movable plate 4 can be limited, avoiding the movable plate 4 from shaking during the movement, which would make it difficult for the movable plate 4 to move normally, thus improving the stability of the movable plate 4.

[0034] refer to Figure 5 Limiting strips 13 are fixedly connected to both sides of the outer side of the upper clamping block 86, and the limiting strips 13 are movably connected to the lower clamping block 85.

[0035] As a technical optimization of this utility model, by setting the limiting strip 13, the upper clamping block 86 can be limited, avoiding the upper clamping block 86 from shaking during use, which would make it difficult for the upper clamping block 86 to clamp the pipe fitting, thus improving the stability of the upper clamping block 86 in use.

[0036] The working principle and usage process of this utility model are as follows: When clamping the pipe fitting, firstly, clamp the pipe fitting onto the left side of the fixed gripper 6, start motor 2 5, which drives the fixed gripper 6 to clamp the pipe fitting. Then, start motor 2, which drives the pipe fitting to a suitable position via screw 3. Then, start electric cylinder 84, which drives the lower front clamping block 85 to move backward. The lower front clamping block 85 drives the upper front clamping block 86 to move backward. After the upper clamping block 86 contacts the surface of the pipe fitting, the pipe fitting will press against the upper clamping block 86 in the opposite direction. After being squeezed by the pipe fitting, 86 moves upward. The upper clamping block 86 drives the spring 87 to move upward. The elastic force of the spring 87 pulls the upper clamping block 86 in the opposite direction to clamp the pipe fitting. After the upper clamping block 86 and the lower clamping block 85 fix the pipe fitting, the motor 4 97 is started. The motor 4 97 drives the drive block 96 to rotate. The drive block 96 drives the belt 95 to rotate. The belt 95 drives the linkage block 94 to rotate. The linkage block 94 drives the screw 2 92 to rotate. The screw 2 92 drives the pressing block 93 to move backward to press against the pipe fitting. At this time, the pipe fitting can be bent, thus achieving the advantage of efficient clamping.

[0037] In summary, this pipe bending machine clamping device, through the coordinated use of processing table 1, motor 1 2, screw 1 3, moving plate 4, motor 2 5, fixed gripper 6, fixed plate 7, clamping mechanism 8, and abutment mechanism 9, solves the problem that most existing pipe bending machine clamping devices are not adjustable and can only be used for pipes of specific sizes. They cannot effectively clamp pipes of different diameters, which greatly limits the application range of the pipe bending machine. When processing pipes of various specifications, multiple different clamping devices are required, increasing equipment costs and storage space, and reducing the efficiency of the clamping devices.
