Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and hydraulic equipment technology, specifically to a crimping mechanism for a pipe crimping machine. Background Technology

[0002] With the continuous development of the pipe crimping machine industry, various crimping mechanisms have been widely used in industrial production. However, some problems have gradually emerged during actual use. For example, the crimping mechanisms used in pipe crimping machines currently on the market have room for improvement in terms of structural design, ease of operation, crimping accuracy, and applicable scope. These problems may lead to reduced processing efficiency or increased operational complexity in certain application scenarios.

[0003] A search revealed a vertical pipe crimping machine with patent number CN113059070B. This design uses multiple hydraulic cylinders to drive the mold closing and pipe crimping operations. A small hydraulic cylinder drives two large hydraulic cylinders for mold closing, and then the large cylinders independently complete the pipe crimping operation. This structure improves energy efficiency and optimizes the overall design to some extent, but it still exhibits some characteristics that require attention in practical applications. First, it relies on the coordinated operation of multiple sets of hydraulic cylinders, resulting in a high complexity of the hydraulic system and potentially increasing maintenance costs. Second, the alignment requirements between the upper and lower modules of the mold assembly are high; large installation errors may lead to uneven crimping, affecting product quality. Furthermore, the device lacks an automatic depth adjustment function, which may require additional time and operational steps when adapting to different pipe specifications, thus limiting its versatility and automation level.

[0004] In addition, a high-pressure pipe crimping machine with patent number CN112045054B was disclosed. This design improves crimping quality and efficiency through a movable mold and motor gear drive. Its structure includes crimping cylinder, bending slide shaft, limiting guide plate, and transmission device. This solution enhances the stability and consistency of the crimping process to a certain extent, but still exhibits some noteworthy characteristics: First, the mold adjustment process requires considerable manual intervention, which is not conducive to achieving fully automated continuous production; second, since the movable mold relies on the guide shaft for movement, wear may occur after long-term operation, thus affecting the crimping accuracy; third, this equipment is mainly suitable for pipes within a specific size range, and its adaptability to irregularly shaped or ultra-large diameter pipes is relatively limited, which restricts its application in diverse production environments.

[0005] The above characteristics indicate that the crimping mechanisms of traditional pipe crimping machines currently on the market have certain improvement needs in meeting the development trends of high precision, high efficiency, and multi-functionality. Therefore, this utility model provides a new type of crimping mechanism for pipe crimping machines that is simple in structure, easy to adjust, has high crimping accuracy, and is widely applicable, in order to overcome the shortcomings of the existing technology and meet the needs of modern industry for intelligent and efficient production equipment.

[0018] The device features a crimping arm design that allows the crimping arm to move along the guide rod, thereby adjusting the distance between the two crimping heads.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides a crimping mechanism for a pipe crimping machine, the overall structure of which is as follows: Figure 1 As shown, the device includes a clamping base 1, a clamping assembly 2, a drive module, and an adjustment module. The clamping base 1 serves as the main support for the entire device. A support frame 7 is vertically arranged at the center of its top. Both ends of the support frame 7 extend to the sides of the clamping base 1, and rotatable threaded rods 8 are installed on the inner sides of each end. The threaded rods 8 are located between the two clamping arms 3 and engage with guide rods 5. The clamping assembly 2 is installed on the top of the clamping base 1 and achieves lateral displacement through the adjustment module. The clamping assembly 2 includes two symmetrically arranged clamping arms 3. Each clamping arm 3 has a clamping head 4 on its inner side, and the central axes of the two clamping heads 4 are on the same horizontal plane. Guide rods 5 are connected to the outer sides of the clamping arms 3. One end of the guide rod 5 passes through the clamping base 1 and extends to its exterior, while the other end is fixedly connected to the clamping arm 3. A compression spring 6 is sleeved on the outer wall of the guide rod 5. One end of the compression spring 6 contacts the inner wall of the clamping base 1, and the other end contacts the outer surface of the clamping arm 3.

[0033] The specific structure of the clamping arm 3 and its cooperation with the guide rod 5 are as follows: Figure 2 As shown, a groove 24 is formed on the top of the clamping arm 3 along its length. The groove 24 is slidably connected to the guide rod 5, allowing the clamping arm 3 to move smoothly along the direction of the guide rod 5. When the two clamping arms 3 move towards each other, they are used to clamp pipes of different specifications. A transmission wheel 21, coaxial with the threaded rod 8, is installed on the top of the support frame 7. The transmission wheels 21 are connected by a synchronous belt 22. A power device 23 for driving the synchronous belt 22 is provided above the clamping base 1. The power device 23 drives the transmission wheels 21 to rotate through the synchronous belt 22, thereby driving the threaded rod 8 to rotate. The rotation of the threaded rod 8 further pushes the two clamping arms 3 to move along the direction of the guide rod 5, completing the clamping operation of the pipe.

[0034] The specific structure of hydraulic cylinder 9 and its connection relationship with connecting rod 12 are as follows: Figure 3As shown, hydraulic cylinders 9 with upward openings are installed at the middle of the top ends of both sides of the clamping base 1. A piston column 10 is installed inside the hydraulic cylinder 9, and an elastic element 11 is provided inside the hydraulic cylinder 9. One end of the elastic element 11 is fixedly connected to the inner wall of the bottom of the hydraulic cylinder 9, and the other end is fixedly connected to the bottom end of the piston column 10. A connecting rod 12 is installed at the top of the piston column 10. A through hole is provided along the thickness of the top of the clamping base 1, and one end of the connecting rod 12 is connected to the outer surface of the clamping arm 3 through the through hole. When the pressure inside the hydraulic cylinder 9 changes, the piston column 10 drives the connecting rod 12 to move up and down, thereby pushing the clamping arm 3 to move along the direction of the guide rod 5, realizing the clamping or loosening operation of the pipe.

[0035] The specific structure of the shunt 15 and its cooperation with the sealing slide 16 are as follows: Figure 4 As shown, a diverter 15 is installed on the top of the clamping base 1, located on one side of the hydraulic cylinder 9. The top opening of the diverter 15 is connected to the output end of the drive module through a hose 14, and the bottom opening of the diverter 15 is connected to the connecting rod 12 through a hose 14. One side opening of the diverter 15 faces the connecting rod 12, and a sealing slide rod 16 is installed laterally inside one side of the diverter 15. A limiting plate 17 located outside the connecting rod 12 is installed at the end of the rod of the sealing slide rod 16. A return spring 18 is sleeved on the rod of the sealing slide rod 16, and the return spring 18 is located between the end face of one side of the diverter 15 and the limiting plate 17. When the connecting rod 12 is subjected to external force, the limiting plate 17 limits the connecting rod 12 to prevent displacement; when the external force disappears, the return spring 18 pushes the limiting plate 17 to reset, and the connecting rod 12 drives the clamping arm 3 to reset under the action of the elastic element 11.

[0036] The specific structure of the adjusting rod 20 and its connection relationship with the clamping arm 3 are as follows: Figure 5 As shown, an adjusting rod 20 is rotatably mounted on the top of the crimping base 1. The outer wall of the adjusting rod 20 is in contact with the top wall of the crimping base 1, and one end of the adjusting rod 20 is always connected to the outer end of the crimping arm 3. The adjustment rod 20's position against the top of the crimping base 1 and its connection to the end of the crimping arm 3 provides support for the crimping arm 3, reduces friction between the crimping arm 3 and the guide rod 5, keeps the crimping head 4 on the same horizontal plane, and ensures uniform contact between the crimping head 4 and the pipe during the crimping process, thus improving the crimping quality when dealing with larger diameter pipes.

[0037] Multiple sets of positioning pins 13 are installed on the inner side of the clamping arm 3, and the number of positioning pins 13 corresponds to the number of clamping heads 4. The ends of the positioning pins 13 face the inner side of the clamping head 4. The multiple sets of positioning pins 13 are connected to the tail of the hydraulic cylinder 9 through hoses 14. When the pressure inside the hydraulic cylinder 9 changes, the positioning pins 13 can pre-fix the position of the pipe before clamping, reduce the shaking of the pipe during clamping, improve clamping accuracy, and automatically disengage after clamping, making it easy to remove the pipe.

[0038] An anti-slip pad 19 is attached to the outer wall of the connecting rod 12, which is away from the distributor 15, and the anti-slip pad 19 is arranged along the length of the connecting rod 12. The anti-slip pad 19 can increase the friction between the connecting rod 12 and the outside world, prevent the connecting rod 12 from slipping during the movement, and thus ensure the stability of the crimping process.

[0039] In practical applications, the pipe to be crimped is first placed between the two crimping heads 4. The power unit 23 is then activated, which drives the transmission wheel 21 to rotate via the synchronous belt 22. The rotation of the transmission wheel 21 further drives the threaded rod 8 to rotate, and the rotation of the threaded rod 8 pushes the two crimping arms 3 to move towards each other along the guide rod 5 until the two crimping heads 4 clamp the pipe. During the crimping process, the pressure inside the hydraulic cylinder 9 changes, and the piston rod 10 drives the connecting rod 12 to move up and down, thereby pushing the crimping arms 3 to move along the guide rod 5, realizing the clamping or loosening operation of the pipe. At the same time, the positioning pin 13 pre-fixes the position of the pipe before crimping, reducing the shaking of the pipe during crimping and improving the crimping accuracy. It also automatically disengages after crimping, facilitating the removal of the pipe. After crimping is completed, the limiting plate 17 disengages from the connecting rod 12, and the connecting rod 12, under the action of the elastic element 11, drives the crimping arms 3 to reset, thus realizing automated operation. Throughout the crimping process, the adjusting rod 20 always supports the crimping arm 3, reducing friction between the crimping arm 3 and the guide rod 5, keeping the crimping head 4 on the same horizontal plane, and ensuring uniform contact between the crimping head 4 and the pipe during the crimping process, thus improving the crimping quality when dealing with larger diameter pipes.

[0040] To enable those skilled in the art to fully understand and implement this utility model, the following explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0041] First, a support frame 7 is installed at the top center of the crimping base 1, and two threaded rods 8 are respectively assembled on the inner sides of both ends of the support frame 7, ensuring that the threaded rods 8 are engaged with the guide rods 5. At this time, the crimping arms 3 are connected to the crimping base 1 through the guide rods 5, and the compression springs 6 are sleeved on the outer wall of the guide rods 5 to provide stable elastic support force. The pipe to be processed is placed between the two crimping heads 4, and the power unit 23 is started. The power unit 23 drives the transmission wheel 21 to rotate through the synchronous belt 22, and the rotation of the transmission wheel 21 further drives the threaded rods 8 to rotate. The rotation of the threaded rods 8 pushes the two crimping arms 3 to move towards each other along the direction of the guide rods 5 until the two crimping heads 4 clamp the pipe. During this process, the cooperation between the sliding groove 24 and the guide rods 5 ensures that the crimping arms 3 can move smoothly, avoiding uneven crimping caused by friction or offset.

[0042] Secondly, when the pressure inside the hydraulic cylinder 9 changes, the piston rod 10 moves up and down under hydraulic pressure, thereby driving the connecting rod 12 to move. The connecting rod 12 is connected to the clamping arm 3 through a through hole, and its movement pushes the clamping arm 3 to further adjust its position along the guide rod 5, thereby realizing the precise clamping or loosening operation of the pipe. The distributor 15 is connected to the hydraulic cylinder 9 and the connecting rod 12 through the hose 14 to ensure the stable transmission of hydraulic oil. The sealing slide rod 16 moves laterally inside the distributor 15, and the limiting plate 17 at its end limits the connecting rod 12 to prevent unnecessary displacement of the connecting rod 12 due to external force interference. When the external force disappears, the return spring 18 pushes the limiting plate 17 to reset, and the connecting rod 12 drives the clamping arm 3 to return to its initial state under the action of the elastic element 11, completing the automatic reset operation.

[0043] Meanwhile, the positioning pins 13 automatically extend before crimping due to pressure changes in the hydraulic cylinder 9, pre-fixing the position of the pipe. The number of positioning pins 13 corresponds to the crimping heads 4, with their ends facing the inside of the crimping heads 4, effectively reducing pipe movement during crimping and thus improving crimping accuracy. After crimping, the positioning pins 13 automatically retract, facilitating the removal of the processed pipe. Furthermore, an anti-slip pad 19 is affixed to the outer wall of the connecting rod 12, which is away from the distributor 15. The anti-slip pad 19 is arranged along the length of the connecting rod 12, increasing friction when the connecting rod 12 contacts the outside, preventing slippage and ensuring the stability of the crimping process.

[0044] Throughout the crimping process, the adjusting rod 20 consistently supports the crimping arm 3. One end of the adjusting rod 20 rests against the top of the crimping base 1, while the other end connects to the end of the crimping arm 3, forming a stable support structure and reducing friction between the crimping arm 3 and the guide rod 5. This design ensures that the crimping head 4 remains on the same horizontal plane, guaranteeing uniform contact between the crimping head 4 and the pipe during crimping. Especially when dealing with larger diameter pipes, the design of the adjusting rod 20 significantly improves crimping quality and avoids crimping defects caused by uneven force.

[0045] Finally, after crimping is complete, the power unit 23 stops operating, the threaded rod 8 stops rotating, and the two crimping arms 3 gradually separate under the elastic action of the compression spring 6, releasing the processed pipe. The entire process achieves fully automated operation from pipe placement and crimping to finished product removal, significantly improving production efficiency while ensuring crimping accuracy and the applicability of the equipment.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
