Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a protective clamp for a pipe bending machine that facilitates the fixing of pipe fittings. Background Technology

[0002] During the bending process of pipe fittings by a pipe bending machine, a high-performance protective clamp plays a crucial role in ensuring the quality of pipe fitting processing, improving production efficiency, and reducing operational difficulty. However, existing protective clamps for pipe bending machines have many problems that need to be solved in practical applications, making it difficult to meet the increasingly diverse and sophisticated needs of pipe fitting processing.

[0003] Traditional protective clamps use a relatively simple fixing method when fixing pipe fittings. For example, they apply pressure to the pipe fitting from one side using a simple clamping device, or rely on some basic positioning structures to restrict some degrees of freedom of the pipe fitting. This fixing method has defects. During the pipe bending process, the pipe fitting is easily displaced or shaken due to the complex bending force. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a protective clamp for a pipe bending machine that facilitates pipe fitting fixation, comprising: a fixed base; an installation component, the outer wall of which is slidably connected to the outer wall of the fixed base, the installation component being used for quick connection to the fixed base; a fixing component, the outer wall of which is slidably connected to the inner wall of the installation component, the fixing component being used for fixing the pipe fitting onto the installation component by pressure clamping; the fixing component includes a slider, the slider having a slot in its wall arranged linearly along the outer wall of the slider, a threaded rod threadedly connected to the inner wall of the slider, a pressure plate rotatably connected to the bottom of the threaded rod, a limit rod fixedly connected to the corners around the pressure plate, a limit post slidably connected to the inner wall of the limit rod, an insert block slidably connected to the inner wall of the slider, and tension springs fixedly connected to the outer walls on both sides of the insert block.

[0006] Preferably, the outer wall of the mounting block is fixedly connected to a positioning block by a connecting rope, and the bottom of the connecting rope is fixedly connected to the top of the positioning block. The outer wall of the positioning block is slidably connected to the inner wall of the fixing seat by a limiting groove, and the limiting groove is opened in the wall of the fixing seat. The limiting groove is used to limit the position of the positioning block. The outer wall of the connecting rope is slidably connected to the inner wall of the fixing seat.

[0007] Preferably, the outer wall of the card block is slidably connected to the inner wall of the fixing seat, the top of the fixing seat is slidably connected to the bottom of the mounting block, the inner wall of the top of the mounting block is slidably connected to the outer wall of the insertion block, the inner wall of the fixing shell is slidably connected to the outer wall of the slider, the outer wall of the mounting block is fixedly connected to the outer wall of the limiting post, and two sets of pull ropes are fixedly connected to the outer wall of the spring plate, and a through groove corresponding to the pull rope is opened in the wall of the spring plate.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This utility model, by setting a fixing component, uses pressure clamping to tightly hold the pipe fitting from both top and bottom directions using a pressure plate and a support plate. At the same time, combined with the restrictive effect of the mounting block on the pipe fitting, a stable fixing structure is formed during the pipe bending process. This multi-directional fixing method can prevent the pipe fitting from shifting or shaking when subjected to bending force, ensuring that the pipe fitting always remains in the predetermined position and posture, thereby guaranteeing the accuracy and quality of pipe bending.

[0010] 2. This utility model, through the installation components and the sliding connection between the mounting block and the inner wall of the fixed base, enables the rapid installation and removal of the mounting block on the fixed base. During installation, simply align the mounting block with the fixed base and insert the mounting block into the corresponding slide rail. Then, utilizing the ingenious design of the pull ropes at both ends of the spring plate, pulling the ropes deforms the spring plate, allowing the mounting block to smoothly insert. After releasing the tension, the elastic restoring force of the spring plate ensures the mounting block tightly fits the slide rail, completing the initial connection. The entire process is simple and quick. This rapid installation feature can save installation time and improve work efficiency in bending pipe processing scenarios where frequent replacement of protective clamps or adjustment of their positions is required.

Example

[0018] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a protective clamp for a pipe bending machine that facilitates pipe fixing, comprising: a fixed base 1; an installation component 2, the outer wall of which is slidably connected to the outer wall of the fixed base 1, the installation component 2 being used for quick connection to the fixed base 1; a fixing component 3, the outer wall of which is slidably connected to the inner wall of the installation component 2, the fixing component 3 being used for fixing the pipe to the installation component 2 by pressure clamping; the fixing component 3 includes a slider 31, the inner wall of which is threadedly connected to a threaded rod 33, the bottom of which is rotatably connected to a pressure plate 34, the corners of which are fixedly connected to a limit rod 35, the inner wall of which is slidably connected to a limit post 36, the inner wall of which is slidably connected to an insert block 32, the outer walls of which are fixedly connected to tension springs 37, and when the pressure plate 34 contacts the pipe, it releases the tension on the insert block 32, at which point the insert block 32 slides into the slider 31 under the elastic restoring force of the tension spring 37.

[0019] The mounting component 2 includes a mounting block 21. A fixing shell 22 is fixedly connected to the inner wall of the top of the mounting block 21. A support plate 23 is fixedly connected to the outer wall of the mounting block 21. A spring plate 24 is fixedly connected to the outer wall of the bottom of the mounting block 21. Locking blocks 25 are fixedly connected to the outer walls on both sides of the spring plate 24. A positioning block 27 is fixedly connected to the outer wall of the mounting block 21 by a connecting rope 26. The bottom of the connecting rope 26 is fixedly connected to the top of the positioning block 27. The outer wall of the locking block 25 is slidably connected to the inner wall of the fixing seat 1. This sliding connection allows the mounting block 21 to slide along the inner wall of the fixing seat 1, enabling quick installation or removal.

[0020] The outer wall of the positioning block 27 is slidably connected to the inner wall of the fixed seat 1 through the limiting groove 4, and the limiting groove 4 is opened in the wall of the fixed seat 1. The outer wall of the connecting rope 26 is slidably connected to the inner wall of the fixed seat 1. The outer wall of the locking block 25 is slidably connected to the inner wall of the fixed seat 1. The top of the fixed seat 1 is slidably connected to the bottom of the mounting block 21. The inner wall of the top of the mounting block 21 is slidably connected to the outer wall of the insert block 32. The inner wall of the fixed shell 22 is slidably connected to the outer wall of the slider 31. The outer wall of the mounting block 21 is fixedly connected to the outer wall of the limiting post 36. Then, the mounting block 21 is aligned with the fixed seat 1 and the locking block 25 is embedded in the corresponding slide of the fixed seat 1. Then, the tension on the two pull ropes is released. The elastic restoring force of the spring plate 24 will cause the locking block 25 to fit tightly in the slide of the fixed seat 1.

[0021] Working principle:

[0022] The protective clamp mainly consists of a fixed base 1, an installation component 2, and a fixing component 3. The fixed base 1 serves as the basic support for the entire protective clamp, providing a stable installation foundation for the installation component 2 and the fixing component 3. The installation component 2 is located on the fixed base 1, and its main function is to achieve a quick connection with the fixed base 1 and provide an installation position for the fixing component 3, thereby working together to complete the fixing operation of the pipe fitting.

[0023] The installation component 2 includes components such as installation block 21, fixing shell 22, support plate 23, spring plate 24, locking block 25, connecting rope 26 and positioning block 27. Installation block 21 is the core part of installation component 2. The fixing shell 22 is fixedly connected to the inner wall of its top, and the support plate 23, spring plate 24 and locking block 25 are fixedly connected to the outer wall.

[0024] The outer wall of the locking block 25 is slidably connected to the inner wall of the fixing seat 1. This sliding connection allows the mounting block 21 to slide along the inner wall of the fixing seat 1, enabling quick installation or disassembly. Pull ropes are connected to both ends of the spring plate 24. During installation, the operator only needs to pull these two pull ropes to bring the two ends of the spring plate 24 closer together using the elasticity of the spring plate 24. Then, the mounting block 21 is aligned with the fixing seat 1 and the locking block 25 is embedded in the corresponding slide of the fixing seat 1. After that, the tension on the two pull ropes is released. The elastic restoring force of the spring plate 24 will cause the locking block 25 to fit tightly in the slide of the fixing seat 1, enhancing the stability of the connection between the mounting block 21 and the fixing seat 1, thus limiting the position of the mounting block 21 and completing the initial connection with the fixing seat 1.

[0025] The outer wall of the mounting block 21 is fixedly connected to the positioning block 27 by the connecting rope 26, and the bottom of the connecting rope 26 is fixedly connected to the top of the positioning block 27. The outer wall of the positioning block 27 is slidably connected to the inner wall of the fixing seat 1 through the limiting groove 4, and the limiting groove 4 is opened in the wall of the fixing seat 1. After the mounting block 21 and the fixing seat 1 are initially connected, the operator holds the positioning block 27 and rotates the positioning block 27 so that it can slide smoothly into the limiting groove 4 through the entrance of the limiting groove 4. After the positioning block 27 is completely in the limiting groove 4, continue to rotate the positioning block 27. The positioning block 27 will gradually be stuck in the limiting groove 4 during the rotation, thereby making the connection between the entire mounting assembly 2 and the fixing seat 1 more stable and providing a reliable foundation for the subsequent fixing operation of the pipe fittings.

[0026] The fixing component 3 is mainly used to fix the pipe fitting to the mounting component 2 by pressure clamping, ensuring that the pipe fitting remains stable during the bending process and does not shift. The fixing component 3 includes components such as slider 31, insert block 32, threaded rod 33, pressure plate 34, limit rod 35 and limit post 36. The inner wall of slider 31 is slidably connected to insert block 32, and the outer walls on both sides of insert block 32 are fixedly connected to tension spring 37. The slider 31 is initially locked. When it is necessary to fix the pipe fitting, the pipe fitting is placed on the support plate 23 on the mounting component 2. When the two sets of insert blocks 32 are slid away from the tension spring 37, the movement of insert block 32 will disengage from the slot of slider 31, thereby releasing the lock on slider 31.

[0027] After the pressure plate 34 contacts the pipe fitting, the tension on the insert block 32 is released. At this time, the insert block 32 will slide into the slider 31 under the elastic restoring force of the tension spring 37. Meanwhile, according to the actual size and shape of the pipe fitting, the operator can manually fine-tune the position of the slider 31 so that the insert block 32 slides into the corresponding slot on the slider 31 under the action of the tension spring 37, restricting the position of the slider 31 and ensuring that the slider 31 will not be displaced when the threaded rod 33 is rotated in the future.

[0028] As the threaded rod 33 moves further downward, the pressure plate 34 applies increasing pressure to the pipe fitting, ultimately securing it firmly to the mounting assembly 2 through pressure clamping. During the bending process, the pressure plate 34 and the support plate 23 tightly clamp the pipe fitting from both above and below. Simultaneously, because the pipe fitting is placed inside the mounting block 21, it further restricts the pipe fitting. The three work together to prevent the pipe fitting from falling off during the bending process. Moreover, this method of securing the pipe fitting with simple operation reduces the time workers spend fixing the pipe fitting compared to traditional pipe fitting fixing methods, thus improving work efficiency.

[0029] Limiting rods 35 are fixedly connected to the corners of the pressure plate 34. Limiting rods 35 are slidably connected to the inner wall of limiting posts 36, and the outer wall of limiting posts 36 is fixedly connected to the outer wall of mounting block 21. During the downward movement of the pressure plate 34, the limiting rods 35 will slide downward along the outer wall of limiting posts 36. This sliding connection method plays a guiding and limiting role in the movement of the pressure plate 34, ensuring that the pressure plate 34 can move downward vertically and smoothly, avoiding the pressure plate 34 from deviating during the movement, thereby ensuring that the pressure plate 34 can press on the pipe fitting and apply uniform pressure to the pipe fitting.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
