[0002] In the fields of metal processing and pipe manufacturing, pipe bending machines are an important piece of equipment widely used for bending various pipes. The working principle of a traditional pipe bending machine is mainly to clamp the end of the pipe through the bending mechanism, and then use the driving mechanism to drive the bending mechanism to move, forcing the pipe to bend at a predetermined angle and direction.

[0003] However, with the development of modern industry, the demand for bending small-diameter, short pipes is increasing, and traditional pipe bending machines are showing significant limitations when dealing with these small pipes. Traditional pipe bending machines are typically designed to handle larger pipe sizes, and their drive mechanisms and motion control systems are often too bulky and complex for small-diameter, short pipes. This not only increases the equipment's manufacturing cost and maintenance difficulty, but also leads to low production efficiency. The shortcomings of traditional pipe bending machines are particularly evident in scenarios where high-volume, high-efficiency production of small-diameter, short pipes is required.

[0029] The following diagrams illustrate various embodiments of the present invention. For clarity, many practical details will be included in the following description. However, it should be understood that these practical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0030] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] This embodiment provides a high-efficiency pipe bender, which is suitable for short pipes with smaller diameters.

[0032] See also Figure 1-2 The high-efficiency pipe bending machine includes a blanking mechanism 100, a pushing mechanism 200, a clamping mechanism 300, and a pipe bending mechanism 400. The blanking mechanism 100, the pushing mechanism 200, the clamping mechanism 300, and the pipe bending mechanism 400 are arranged on a machine platform 500. The discharge end of the blanking mechanism 100 is arranged near the discharge port 510 of the machine platform 500, the pushing mechanism 200 is arranged near the blanking mechanism 100, and the clamping mechanism 300 and the pipe bending mechanism 400 are arranged near the discharge end of the blanking mechanism 100.

[0033] The unloading mechanism 100 is used to carry the pipe material, the pushing mechanism 200 is used to push the pipe material, the clamping mechanism 300 is used to clamp the pipe material, and the bending mechanism 400 is used to bend the pipe material. In specific applications, the unloading mechanism 100 carries the pipe material to be bent. The pushing mechanism 200 pushes the pipe material to the discharge end of the unloading mechanism 100. The clamping mechanism 300 clamps the pipe material at the discharge end of the unloading mechanism 100. The bending mechanism 400 then bends the pipe material clamped by the clamping mechanism 300. When the pushing mechanism 200 pushes the next pipe material to be bent, the bent pipe material is pushed away from the discharge end of the unloading mechanism 100 by the new pipe material to be bent, and then falls into the discharge port 510.

[0034] See also Figure 1-4The unloading mechanism 100 includes a hopper 110, a unloading channel 120, and a feeding channel 130. The hopper 110 and the feeding channel 130 are mounted on the machine platform 500. The hopper 110 is positioned above the unloading channel 120, while the feeding channel 130 is positioned below the unloading channel 120. One end of the unloading channel 120 is connected to the hopper 110, while the other end of the unloading channel 120 is connected to the feeding channel 130. The unloading channel 120 extends along the Z-axis, while the feeding channel 130 extends along the Y-axis. One end of the feeding channel 130 is positioned near the discharge port 510, and the end of the feeding channel 130 near the discharge port 510 constitutes the discharge end of the unloading mechanism 100. When pipe materials are placed in the hopper 110, they naturally fall into the unloading channel 120 under the action of gravity, and then fall into the feeding channel 130.

[0035] Furthermore, the width of hopper 110 in the Y-axis direction is adapted to the length of a single pipe, allowing the pipe to be placed in hopper 110 in a directional manner, achieving a uniform material distribution effect. The lower end of hopper 110, serving as the discharge end of hopper 110, is sized to accommodate a single pipe. This limits the amount of pipe material that falls, ensuring that only a single pipe is dropped at a time, allowing the pipe material in hopper 110 to fall into the discharge channel 120 in an orderly and directional manner. Furthermore, the width of discharge channel 120 in the X-axis direction is adapted to the diameter of a single pipe, and the length of discharge channel 120 in the Y-axis direction is adapted to the length of a single pipe, ensuring that discharge channel 120 can only accommodate a single vertical row of pipes, allowing the pipe material in discharge channel 120 to fall into the feed channel 130 in an orderly and directional manner. In addition, the width of the feeding channel 130 in the X-axis direction is adapted to the diameter of the pipe material, on the one hand to prevent the pipe materials from being arranged side by side in the X-axis direction, and on the other hand to prevent the pipe materials from having a large offset in the X-axis direction, so that the pushing mechanism 200 can accurately push out a single pipe material.

[0036] To prevent the pipe material from getting stuck in the discharge channel 120 and being unable to fall into the feed channel 130, the discharge mechanism 100 is further provided with a material assembly 140. The material assembly 140 assists in the downward movement of the pipe material, ensuring that the pipe material in the discharge channel 120 can be smoothly transported to the feed channel 130. Referring to the figure, the material assembly 140 includes a material drive 141 and a material member 142. The material drive 141 is mounted on the machine 500. The material member 142 is connected to the output end of the material drive 141. The tip of the material member 142 extends into the discharge channel 120. The material drive 141 drives the material member 142 to move along the Z-axis. During this process, the tip of the material member 142 moves the pipe material in the discharge channel 120, thereby organizing the pipe material in the discharge channel 120 and preventing the pipe material from getting stuck in the discharge channel 120. In this embodiment, the monolithic member 142 is wedge-shaped, and the shape of its tip is conducive to moving the pipe material; the monolithic member driving member 141 adopts a single-acting cylinder, and the output end of the monolithic member driving member 141 is the piston rod of the single-acting cylinder.

[0037] See also Figure 1-4 The pushing mechanism 200 includes a pushing drive 210 and a pushing member 220. The output end of the pushing drive 210 is mounted on the machine platform 500. The main body of the pushing drive 210 is connected to one end of the pushing member 220, and the other end of the pushing member 220 is movably inserted into the feeding channel 130. During operation, the main body of the pushing drive 210 drives the pushing member 220 to move along the Y-axis direction, and the pushing member 220 pushes the pipe material in the feeding channel 130 to the end of the feeding channel 130 near the discharge port 510. The pipe material is exposed at the end of the feeding channel 130 near the discharge port 510. In this embodiment, the pushing drive 210 adopts a double-acting cylinder. The cylinder body of the double-acting cylinder serves as the main body of the pushing drive 210, and the piston rod of the double-acting cylinder serves as the output end of the pushing drive 210. The pushing member 220 adopts a long rod.

[0038] See also Figure 1 、 3 5, the material clamping mechanism 300 includes a fixed clamping die 310, a movable clamping die 320, and a clamping drive 330. The fixed clamping die 310, movable clamping die 320, and clamping drive 330 are respectively mounted on the machine platform 500. The fixed clamping die 310 is arranged between the feeding channel 130 and the discharge port 510. The movable clamping die 320 and the fixed clamping die 310 are arranged opposite each other along the X-axis direction. The movable clamping die 320 is connected to the output end of the clamping drive 330. The clamping drive 330 drives the movable clamping die 320 and the fixed clamping die 310 to close the mold. The closing of the movable clamping die 320 and the fixed clamping die 310 clamps the tube material extending from the end of the feeding channel 130 near the discharge port 510.

[0039] Specifically, the fixed die 310 has a fixed die material clamping channel 311, and the movable die 320 has a movable die material clamping channel 321. The fixed die material clamping channel 311 and the movable die material clamping channel 321 are arranged opposite each other. The fixed die material clamping channel 311 is aligned with the feeding channel 130 to ensure that the pipe material can smoothly enter the fixed die material clamping channel 311, so that the fixed die material clamping channel 311 and the movable die material clamping channel 321 cooperate to clamp the pipe material. The fixed die 310 also has a fixed die bending channel 312, which is connected to the fixed die bending channel 312. The path of the fixed die bending channel 312 is adapted to the bending direction and angle of the pipe material.

[0040] Furthermore, the clamping movable mold 320 is installed on the machine platform 500 through the movable mold mounting seat 322. There is a movable virtual position between the clamping movable mold 320 and the movable mold mounting seat 322, so that the clamping movable mold 320 can only move a distance of 0.5~2mm along the X-axis direction, shortening the distance between the fixed mold clamping channel 311 and the movable mold clamping channel 321, and preventing the tube material from becoming too loose and falling off after entering the fixed mold clamping channel 311.

[0041] Furthermore, the output end of the clamping driver 330 is connected to the clamping movable die 320 via an elastic member 340. Specifically, one end of the elastic member 340 is connected to the output end of the clamping driver 330, while the other end is connected to the clamping movable die 320. The elastic member 340 acts as a buffer, maintaining a constant output force. This prevents the output force of the clamping driver 330 from being directly applied to the clamping movable die 320, thereby reducing collision wear between the clamping fixed die 310 and the clamping movable die 320. Furthermore, it prevents excessive extrusion and deformation of the pipe material during the clamping fixed die 310 and the clamping movable die 320. In this embodiment, the clamping driver 330 is a pneumatic cylinder, with the output end of the clamping driver 330 formed by the cylinder's piston rod, while the elastic member 340 is a spring.

[0042] See also Figure 1 、 3 5. The pipe bending mechanism 400 includes a pipe bending driver 410 and a pipe bending movable die 420. The pipe bending driver 410 is mounted on the machine platform 500. The pipe bending movable die 420 is connected to the output end of the pipe bending driver 410. The pipe bending movable die 420 is arranged relative to the material clamping fixed die 310. The pipe bending driver 410 drives the pipe bending movable die 420 to move so as to close or open the pipe bending movable die 420 with the material clamping fixed die 310. In this embodiment, the pipe bending driver 410 is a cylinder, and the output end of the pipe bending driver 410 is formed by the piston rod of the cylinder.

[0043] Furthermore, the movable tube bending die 420 has a movable die bending track 421 on the end thereof facing the fixed die 310. The movable die bending track 421 is arranged opposite the fixed die bending track 312. When the tube bending driver 410 drives the movable tube bending die 420 toward the fixed die 310, and the tube material begins to enter the movable die bending track 421, the movable tube bending die 420 acts on the tube material, pushing the tube material to bend along the path of the fixed die bending track 312, thereby achieving tube bending.

[0044] The following describes the working process of the efficient pipe bending machine:

[0045] Unloading process: The hopper 110 contains a plurality of pipes to be bent. Under the action of gravity, the pipes naturally fall into the unloading channel 120 and then fall into the feeding channel 130. During this process, the pipes in the unloading channel 120 are moved by the material-manipulating assembly 140 to ensure that the pipes in the unloading channel 120 can fall smoothly into the feeding channel 130.

[0046] Pushing process: After the pipe material enters the feeding channel 130, the pushing drive 210 drives the pushing member 220 to move, pushing the pipe material at the bottom of the feeding channel 130 to the end of the feeding channel 130 close to the discharge port 510, and making the pipe material emerge from the end of the feeding channel 130 close to the discharge port 510;

[0047] Clamping process: At this time, the exposed section of the tube material enters the fixed mold clamping channel 311, and the clamping driving member 330 drives the clamping movable mold 320 and the clamping fixed mold 310 to clamp the section of the tube material through the clamping of the clamping movable mold 320 and the clamping fixed mold 310;

[0048] Tube bending process: Subsequently, the tube bending drive 410 drives the tube bending movable die 420 to move, and the tube bending movable die 420 is clamped with the material clamping fixed die 310. During the process, after the tube material begins to enter the movable die bending path 421, the tube bending movable die 420 begins to act on the tube material, pushing the tube material to bend along the path of the fixed die bending path 312.

[0049] Adjustment process: After the tube bending is completed, the pusher drive 210 drives the pusher 220 to retract, the clamping drive 330 drives the clamping movable die 320 to retract, and the tube bending drive 410 drives the tube bending movable die 420 to retract; wherein, after the pusher 220 retracts, the tube to be bent continues to fall to the bottom of the feeding channel 130;

[0050] In the material pushing process, the pusher driving member 210 drives the pusher member 220 to move again, pushing the pipe material at the bottom of the feeding channel 130 toward the end of the feeding channel 130 close to the discharge port 510. The pipe material pushes the bent pipe material at the end of the feeding channel 130 close to the discharge port 510, and the bent pipe material falls through the discharge port 510.

[0051] After the next pipe to be bent is in place, the clamping process, bending process, adjustment process and pushing process are carried out in sequence, and this cycle is repeated.

[0052] In summary, this efficient pipe bender effectively shortens the stroke of each process through the rational arrangement of the feeding mechanism, pushing mechanism, clamping mechanism, and pipe bending mechanism, thereby improving production and efficiency, especially for small-diameter pipes. At the same time, this efficient pipe bender also simplifies the structure of each mechanism, making it compact and lightweight. This not only reduces the floor space, but also reduces manufacturing costs and the complexity of subsequent maintenance, bringing higher economic benefits and convenient operation and maintenance to users.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
