Description

[0002] A copper tube bending device is a specialized piece of equipment for bending copper tubes. It uses mechanical structures and other power methods to precisely bend straight copper tubes according to preset angles, arcs, or shapes to meet the installation and usage requirements of different scenarios. Its main function is to adapt copper tubes to complex spatial layouts.

[0003] For example, a Chinese patent document discloses an auxiliary tooling for pipe bending (publication number: CN212264345U). This patent includes a pipe bending handle for controlling the movement of the bending wheel, with the bending wheel positioned below the handle. Workers can easily control the rotation of the bending wheel around a fixed wheel axis using the handle, thus facilitating pipe bending and enabling rapid, high-volume production of the pipes needed by manufacturers, thereby improving production efficiency.

[0004] However, during the bending process, if the contact point between the bending wheel and the copper pipe is too small, the stress area of ​​the copper pipe will be concentrated, resulting in excessive compression and deformation during bending. This will cause obvious pit marks on the surface, affecting the appearance quality and structural integrity of the copper pipe. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0017] Reference Figures 1 to 6 In this embodiment of the utility model, a copper tube bending device with a quick fixing function includes: an operating platform 1, which serves as the basic load-bearing structure of the entire device, providing a horizontal work surface for placing copper tubes and installing various components, and is an operating platform for bending processing. Several sets of detachable guide wheel fixing rods 2 are installed on the surface of the operating platform 1. The outer side of each set of guide wheel fixing rods 2 is rotatably connected to a bending guide wheel 3 through a rotating shaft. The bending guide wheel 3 cooperates with other components to form a clamping and guiding mechanism for the copper tube, assisting the copper tube to bend along a preset path and ensuring the stability of the bending process. A bending mechanism 4 is provided at the top of one set of guide wheel fixing rods 2, and a fixing mechanism 5 is provided at the other end of the surface of the operating platform 1.

[0018] Reference Figures 1 to 5 The bending mechanism 4 includes an operating plate 41, a bending block 42, and a bending groove 43. The operating plate 41 is rotatably mounted on the upper end of the guide wheel fixing rod 2. The bending block 42 is slidably mounted on one bottom end of the operating plate 41. The bending groove 43 is located on the inner side of the bending block 42.

[0019] The bending mechanism 4 also includes a drive assembly 44, a fastening bolt 45, and a nut 46. The drive assembly 44 is rotatably disposed at the bottom of the operating plate 41, the fastening bolt 45 is disposed on one side of the bending block 42, and the nut 46 is disposed on the other side of the bending block 42.

[0020] The bending mechanism 4 includes a connecting component 47, a limiting ring groove 48, a horizontal handle 49, and a vertical handle 410. The connecting component 47 is located at the head of the operating plate 41, the limiting ring groove 48 is formed and connected to the top surface of the operating plate 41, and the horizontal handle 49 and the vertical handle 410 are fixedly connected to the top surface of the operating plate 41. The horizontal handle 49 and the vertical handle 410 facilitate the operator to rotate the operating plate 41, thereby driving the bending block 42 to cooperate with the bending guide wheel 3 to perform bending operations on the copper tube. The design of the bending groove 43, due to its certain length, increases the contact surface with the copper tube during the bending operation, disperses the extrusion force during bending, reduces the probability of deformation, and avoids the fixed point being too small during operation, which could lead to copper contact and extrusion deformation, resulting in obvious pit marks on the surface. This ensures both appearance quality and avoids structural hazards caused by local stress concentration.

[0021] The drive assembly 44 includes a base 441 and a lead screw 442. The base 441 is fixedly connected to the bottom of the operating plate 41, and the lead screw 442 passes through the base 441 and is threaded into the base 441.

[0022] The drive assembly 44 also includes an insert plate 443 and an adjusting wheel 444. The insert plate 443 is rotatably connected to the tail of the lead screw 442, and the adjusting wheel 444 is fixedly connected to the head of the lead screw 442. The insert plate 443 is inserted into the back of the bend block 42. The fastening bolt 45 passes through the insert plate 443 and the bend block 42 and is threadedly connected to the nut 46. By rotating the adjusting wheel 444, the lead screw 442 moves within the base 441, causing the insert plate 443 to push the bend block 42 to slide until the bend groove 43 fits against the copper pipe. This allows for flexible adjustment, ensuring that the bend groove 43 fits precisely against copper pipes of different specifications. The method of fixing the bend block 42 to the insert plate 443 using the fastening bolt 45 and the nut 46 facilitates the replacement of the bend block 42.

[0023] The connecting assembly 47 includes a connecting bolt 471 and a limiting ring block 472. The connecting bolt 471 is located above the head of the operating plate 41, and the other end of the connecting bolt 471 passes through the operating plate 41 and is threadedly connected to the guide wheel fixing rod 2. The limiting ring block 472 is fixedly connected to the upper outer side of the connecting bolt 471, and the limiting ring block 472 is adapted to the limiting ring groove 48. The operating plate 41 is connected to the corresponding guide wheel fixing rod 2 through the connecting assembly 47. The connecting bolt 471 passes through the operating plate 41 and is threadedly connected to the guide wheel fixing rod 2. The limiting ring block 472 is embedded in the limiting ring groove 48, ensuring that the operating plate 41 can rotate stably around the guide wheel fixing rod 2. This method facilitates the disassembly and installation of the entire bending mechanism 4, and is convenient for later maintenance, replacement of parts, or adjustment of processing position.

[0024] Reference Figure 1 and Figure 6 The fixing mechanism 5 includes a fixing base 51 and a fixing cover 52. The fixing base 51 is fixedly connected to the operating table 1, and the fixing cover 52 is hinged above the fixing base 51.

[0025] The fixing mechanism 5 also includes a threaded rod 53, a circular patch 54, and a handle 55. The threaded rod 53 is located above the fixing cover 52, the circular patch 54 is fixedly connected to the upper outer side of the threaded rod 53, and the handle 55 is fixedly connected to the top of the threaded rod 53.

[0026] The other end of the threaded rod 53 passes through the fixed cover 52 and the fixed base 51. The threaded rod 53 is threadedly connected to the fixed cover 52 and the fixed base 51. The circular patch 54 is attached to the fixed cover 52. One end of the copper tube is placed inside the fixed cover 52. After the fixed cover 52 is closed, the copper tube is limited. Then, by turning the handle 55, the threaded rod 53 is rotated, so that the threaded rod 53 is connected to the fixed base 51, and the circular patch 54 is tightly attached to the fixed cover 52. This ensures that the fixed cover 52 and the fixed base 51 are tightly fitted, ensuring that the copper tube will not shift during the bending process, thus guaranteeing the bending position of the tube and providing a stable foundation for precise bending.

[0027] The working principle of this utility model is as follows: When in use, the copper tube to be bent is first placed on the operating table 1, and one end of the copper tube is fixed by the fixing mechanism 5. The upper cover 52 is used to place one end of the copper tube. Then, the upper cover 52 is put on to limit the copper tube. Then, the threaded rod 53 is rotated by turning the handle 55, so that the threaded rod 53 is connected to the fixed base 51, and the circular patch 54 is tightly attached to the upper cover 52, so that the upper cover 52 and the fixed base 51 are tightly attached to each other, ensuring that the copper tube will not be displaced during the bending process, thereby ensuring the bending position of the tube and providing a stable foundation for precise bending. Subsequently, the position of the bending mechanism 4 is adjusted according to the bending requirements; the position of the bending block 42 is adjusted by the drive component 44, and the adjusting wheel 444 is rotated to move the lead screw 442 within the base 441, driving the insert plate 443 to push the bending block 42 to slide until the bending groove 43 is in contact with the copper tube. This allows for flexible adjustment, ensuring that the bending groove 43 is precisely in contact with copper tubes of different specifications. Due to the design of the bending groove 43, its certain length increases the contact surface with the copper tube during the bending operation, dispersing the extrusion force during bending and reducing the probability of deformation. This avoids the fixed point being too small during operation, which could lead to copper contact and extrusion deformation, resulting in obvious pit marks on the surface. This ensures both appearance quality and avoids structural hazards caused by local stress concentration. The method of fixing the bending block 42 to the insert plate 443 using fastening bolts 45 and nuts 46 facilitates the replacement of the bending block 42. The operating plate 41 is connected to the corresponding guide wheel fixing rod 2 by the connecting component 47. The connecting bolt 471 passes through the operating plate 41 and is threadedly connected to the guide wheel fixing rod 2. The limiting ring block 472 is embedded in the limiting ring groove 48 to ensure that the operating plate 41 can rotate stably around the guide wheel fixing rod 2. This method makes it easy to disassemble and install the entire bending mechanism 4, which is convenient for later maintenance, replacement of parts or adjustment of processing position.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
