Technical Field
[0001] This utility model relates to the field of pipe bending machine technology, and more specifically, to a clamping mechanism and a pipe bending machine. Background Technology
[0002] In the existing pipe bending machine technology field, the bending of pipes usually relies on the cooperation between the bending wheel and the clamping block. In order to achieve precise bending of the pipe, both the bending wheel and the clamping block are designed with slots for limiting the pipe. These slots are designed to ensure that the pipe can maintain a stable position during the bending process. However, there is a significant deficiency in the design of the existing technology: when the operator places the pipe to be processed, he or she needs to manually adjust the position of the pipe so that it can be clamped in the slot between the bending wheel and the clamping block.
[0003] Manual positioning not only increases operational complexity but also readily introduces human error. Because the precision and consistency of manual operation are difficult to guarantee, pipe placement often deviates, affecting the quality of pipe bending. Therefore, we have made improvements by proposing a clamping mechanism and a pipe bending machine. Summary of the Invention

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0031] As described in the background art, when placing the pipe to be processed, the operator needs to manually adjust the position of the pipe so that it can be clamped in the groove between the bending wheel and the clamping block. The manual positioning process not only increases the complexity of the operation, but also easily introduces human error. Since the accuracy and consistency of manual operation are difficult to guarantee, the placement position of the pipe often deviates, affecting the quality of the pipe bend.
[0032] To solve this technical problem, this utility model provides a clamping mechanism and a pipe bending machine, which are applied to pipe bending.
[0033] For details, please refer to Figures 1-3The clamping mechanism specifically includes:
[0034] The driving component is connected to the clamping block body 202. The clamping block body 202 has at least two side grooves 203. A hand-tightening bolt 204 is provided between the side grooves 203 and the clamping block body 202. The outer surface of the hand-tightening bolt 204 is threadedly connected to a support plate 205 located in the side groove 203. The support plate 205 is used to support the pipe.
[0035] The clamping mechanism and pipe bending machine provided by this utility model, by setting a support plate 205 on the clamping block body 202, provides a support positioning point for the pipe, so that the pipe can automatically correspond to the position of the slot when placed, thereby greatly reducing the error of manual positioning. The design of the support plate 205 simplifies the pipe placement process, and the staff no longer need to perform tedious manual positioning operations, which greatly improves work efficiency and operation convenience.
[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0037] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0039] Example 1, please refer to Figures 1-3 A clamping mechanism includes a driving component connected to a clamping block body 202. At least two side grooves 203 are formed on the clamping block body 202. A hand-tightening bolt 204 is provided between the side grooves 203 and the clamping block body 202. A support plate 205 located within the side grooves 203 is threaded onto the outer surface of the hand-tightening bolt 204. The support plate 205 supports the pipe and provides a support positioning point for the pipe, enabling the pipe to automatically align with the position of the clamping groove during placement, thereby greatly reducing errors from manual positioning. The design of the support plate 205 simplifies the pipe placement process, eliminating the need for tedious manual positioning operations and significantly improving work efficiency and ease of operation.
[0040] Furthermore, such as Figures 1-3As shown, the driving component includes a side groove 203, on which a hydraulic cylinder 2 is mounted. One end of the hydraulic cylinder 2 passes through the side groove 203 and is connected to a connecting plate 201. One side of the connecting plate 201 is connected to the clamping block body 202. The hydraulic cylinder 2 and the connecting plate 201 can drive the clamping block body 202 to move, thereby adjusting the position of the clamping block body 202.
[0041] Furthermore, such as Figures 1-3 As shown, a support rod 207 is fixedly connected to the side of the connecting plate 201 away from the clamping block body 202. The end of the support rod 207 away from the connecting plate 201 passes through the side groove 203. The support rod 207 can provide auxiliary limiting for the connecting plate 201 to improve the stability of the movement of the connecting plate 201 and the clamping block body 202.
[0042] Example 2, please refer to Figures 1-2 A pipe bending machine using a clamping mechanism also includes a support platform 1. A geared motor 301 is mounted on the bottom of the support platform 1. The output shaft of the geared motor 301 passes through the support platform 1 and extends above the support platform 1 and is connected to a main shaft 3. A bending wheel body 302 and a rotating plate 303 located below the bending wheel body 302 are connected to the main shaft 3. A side groove 203 is installed on the top of the rotating plate 303. During the rotation of the geared motor 301, the rotating plate 303 can be driven to rotate through the main shaft 3.
[0043] Example 3 further optimizes the pipe bending machine provided in Example 2, specifically, as follows: Figure 1 and Figure 3 As shown, a protective disc 4 is fitted on the outer surface of the main shaft 3 above the bending wheel body 302. The protective disc 4 can limit the pipe during the bending process, reduce the pipe from springing up, and improve the safety of the bending process.
[0044] Furthermore, a limiting component is provided at the top of the spindle 3, which is used to limit the movement of the protective disc 4.
[0045] Furthermore, such as Figures 1-4 As shown, the limiting component includes a groove 5 formed on the top of the main shaft 3, a connecting shaft 502 installed in the groove 5, and a limiting rod 503 sleeved on the outer surface of the connecting shaft 502. The limiting rod 503 contacts the top of the protective disc 4 and can rotate around the connecting shaft 502. When the limiting rod 503 rotates to the vertical position, it can contact the fixing of the protective disc 4.
[0046] Furthermore, such as Figure 4As shown, the top and side of the spindle 3 are provided with limiting grooves 501, and the limiting rod 503 is provided with a sliding groove 504. A connecting rod 505 is inserted into the sliding groove 504. One end of the connecting rod 505 passes through the limiting rod 503 and extends to the outside of the limiting rod 503. A limiting strip 506 located in the sliding groove 504 is fixedly connected to the outer surface of the connecting rod 505. The limiting strip 506 is inserted into the limiting groove 501 on the side of the spindle 3. The limiting rod 503 can be limited by the insertion of the limiting strip 506 into the limiting groove 501.
[0047] Furthermore, such as Figure 4 As shown, a spring 507 is sleeved on the outer surface of the connecting rod 505. The spring 507 is located in the slide groove 504 and contacts the side of the limiting strip 506. The force of the spring 507 can improve the stability of the insertion of the limiting strip 506 and the limiting groove 501. Pulling the connecting rod 505 causes the connecting rod 505 to move the limiting strip 506, so that the limiting strip 506 separates from the limiting groove 501. Rotate the limiting rod 503 around the connecting shaft 502 until it is upright, and pull the protective plate 4 upward to remove the protective plate 4 for easy replacement. During installation, the protective plate 4 is sleeved on the outer surface of the main shaft 3. After pulling the connecting rod 505, rotate the limiting rod 503 around the connecting shaft 502 so that the limiting rod 503 contacts the top of the protective plate 4. Insert the limiting strip 506 into the corresponding limiting groove 501.
[0048] Furthermore, such as Figure 4 As shown, a support frame 101 is fixedly installed at the bottom of the support platform 1, and the support frame 101 is used to support the support platform 1.
[0049] The clamping mechanism and pipe bending machine provided by this utility model are used as follows:
[0050] An existing clamp, such as a bench vise, is installed on the side of the support platform 1. The pipe is placed on top of the support plate 205, with the pipe positioned between the bending wheel body 302 and the clamping block body 202. The hydraulic cylinder 2 pushes the clamping block body 202 toward the bending wheel body 302 via the connecting plate 201, so that the pipe is confined between the bending wheel body 302 and the clamping block body 202. Then, the pipe is clamped by the existing clamp. The reduction motor 301 drives the main shaft 3 and the rotating plate 303 to rotate. During the rotation of the rotating plate 303, the clamping block body 202 is driven to rotate around the main shaft 3 to perform a pipe bending operation.
