DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings and through examples. The following examples are intended to explain the present invention, but the present invention is not limited to the following examples.

[0022] See also Figure 1-3 The present embodiment relates to a multi-angle pipe bending device for wrought iron furniture, comprising a fixed frame 1 and a pipe bending assembly 2 arranged thereon, the pipe bending assembly 2 comprising a bending head 21 rotatably arranged on the fixed frame 1 and a first fixed pipe 22 arranged on the bending head 21, and a second fixed pipe 23 with an adapting structure installed at a corresponding position of the fixed frame 1 along one side of the first fixed pipe 22 on the bending head 21, the bending head 21 is driven to rotate by a driving component 211 arranged on the fixed frame 1, the bending head 21 and the first fixed pipe 22 and the second fixed pipe 23 thereon are arranged in a split structure and are respectively slidably connected by multiple groups of connecting rods 24 arranged thereon and multiple groups of compression springs 241 sleeved on the connecting rods 24.

[0023] Specifically in this embodiment, Figure 1 The overall structural setting of the multi-angle pipe bending device of this iron furniture and the corresponding pipe fixing method are shown. The pipe can be sequentially passed through the second fixed pipe 23 on the fixing frame 1 and along the second fixed pipe 23 to reach the bending head 21, and then passed through the first fixed pipe 22 set on the bending head 21. When the bending point is reached, the controller 3 for controlling the rotation of the driving component 211 provided on the fixing frame 1 can be used to drive the bending head 21 and the pipe clamped thereon by the first fixed pipe 22 to perform a bending process in the corresponding direction along the fixing frame 1 and its corresponding bending point and the adapting guide groove provided on the bending head 21. The rotation state of the bending head 21 during the specific bending can be seen in FIG. Figure 2As shown, the corresponding structures and specific connection methods of the bending head 21 and the first fixed pipe 22 and the second fixed pipe 23 thereon using the split structure can be seen in Figure 3 As shown, the first fixed pipe 22 is combined with the adapting structure of the bending head 21 and the second fixed pipe 23, which can be set with a conventional embracing clamp structure. The connecting rod 24 is set as a sliding rod structure and the head end is rotatably provided with a bolt member 242 connected by a threaded structure, and cooperates with the multiple groups of compression springs 241 provided on the corresponding position of the connecting rod 24. The corresponding end of the second fixed pipe 23 installed on the fixing frame 1 and arranged in a corresponding structure is adapted and slidably set on the fixing frame 1 through the connecting rod 24. In addition, the upper part of the bending head 21 is connected to the driving part. The head end of the connecting shaft 212 connected to the member 211 is rotatably provided with an adapting lock ring 2121 connected by a threaded structure, thereby realizing the telescopic adjustment process of the bending head 21, the first fixed pipe 22 and the second fixed pipe 23. Specifically, according to the specific specifications of the adapting pipe to be bent, multiple groups of connecting rods 24 set at the corresponding positions of the corresponding main bodies and the adapting compression springs 241 sleeved thereon and the bolt members 242 rotatably provided at the head end can adapt to the specific specifications of the pipe to perform telescopic movement in the corresponding direction and corresponding pre-setting. The process of adjusting the tightening force, at the same time, during the rotation of the bending head 21, the corresponding retractable process of the bending head 21 and its first fixed pipe 22 and second fixed pipe 23 does not affect the normal bending process of the pipe, and can play a certain buffering effect on the direct stress generated at the moment of pipe bending. Compared with the conventional factory-used batch pipe bending machine structure, this multi-angle pipe bending device for iron furniture can cooperate with the structural setting of the bending head 21 and the first fixed pipe 22 and the second pipe thereon in the bending assembly 2, and can perform adaptive retractable clamping processes for pipes of different specifications and sizes, with high applicability and convenient operation. In addition, this pipe bending device can drive the bending head 21 to bend the pipe at different angles through the driving component 211. At the same time, the overall structure of this pipe bending device is simple and small in size, which is convenient to use and carry. It has high applicability for some small decoration companies to carry out on-site assembly of iron furniture and corresponding on-site pipe bending and adjustment processes, meet different use environments and use requirements, and improve the flexibility of use and the bending efficiency of the corresponding pipes.

[0024] The bending head 21 and the first fixed pipe 22 thereon are pasted with an adaptive anti-slip pad 252 on the clamping surface 25 for fixing the pipe. The addition of the anti-slip pad 252 on the corresponding clamping surface 25 of the bending head 21 and the first fixed pipe 22 can play a certain anti-slip and shock-absorbing effect, improve the position stability of the pipe during the bending process and the corresponding bending effect, and also play a certain protective role on the surface of the pipe during the bending process, effectively reducing the unnecessary wear on the surface of the pipe.

[0025] The clamping surfaces 25 corresponding to the first fixed pipe 22 and the second fixed pipe 23 are further provided with a plurality of rib grooves 251. The clamping surfaces 25 corresponding to the first fixed pipe 22 and the second fixed pipe 23 can be staggered to form a plurality of rib grooves 251 or be pasted with anti-slip pads 252. The plurality of rib grooves 251 can be adapted to the specific shape of the corresponding pipe to be bent, and are suitable for the fixing process of different types of pipes and further improve the stability of the first fixed pipe 22 and the second fixed pipe 23 in clamping and fixing the pipe, thereby improving the flexibility of use and the bending effect and bending stability of the corresponding pipe.

[0026] The bending head 21 and the first fixed pipe 22 thereon as well as the driving component 211 and the second fixed pipe 23 on the fixing frame 1 are all mounted on the fixing frame 1 through a detachable structure. For details, see Figure 3 As shown, the bending head 21 is connected to the driving component 211 on the fixed frame 1 and is rotatably provided with a keyway structure 2122 on the connecting shaft 212 to perform the synchronous rotation and up and down sliding process of the bending head 21, and the adapter lock ring 2121 connected by a threaded structure is provided on the head end of the connecting shaft 212 to realize the detachable connection process of the bending head 21 and the first fixed pipe 22 on the connecting shaft 212, and the second fixed pipe 23 is detachably installed on the corresponding position of the fixed frame 1 through the bolt member 242 and the connecting rod 24 provided thereon, and the driving component 211 can be removed from Figure 4 It can be seen that the bolt member 242 is detachably installed at a fixed corresponding position to drive the bending head 21 to rotate. The bending pipe assembly 2 shown in the figure adopts such a detachable structure to further improve the detachability and disassembly convenience of the bending pipe device, facilitate daily inspection and subsequent maintenance processes, and improve adjustment flexibility and maintenance efficiency.

[0027] The bending head 21 and the first fixed pipe 22 thereon are provided with a connecting plate 26 for connecting with multiple groups of connecting rods 24 and forming an adaptive structure, such as Figure 1 or Figure 3 As shown, the addition of the connecting plate 26 and the corresponding structural setting can be used to pass the corresponding connecting shaft 212 and multiple groups of connecting rods 24 through the several through holes 261 opened on the connecting plate 26, and the preload force adjustment process can be performed through the corresponding bolt members 242 and the locking ring 2121. The number of connecting rods 24 on the corresponding bending head 21 and the first fixed pipe 22 can be reduced accordingly, and the adjustment convenience and operation efficiency of the bending head 21 and the first fixed pipe 22 can be effectively improved while ensuring the connection stability of the bending head 21 and the first fixed pipe 22.

[0028] The bottom fixing frame 1 of the bending head 21 is also equipped with a dial 4, and the dial 4 is arranged around the bottom periphery of the bending head 21 and a pointer 213 is arranged at the corresponding position of the bending head 21. Figure 3 As shown, the addition of the corresponding dial 4 on the fixed frame 1 can determine the specific bending angle of the pipe according to the relative position of the pointer 213 on the bending head 21 and the corresponding scale on the dial 4 during the rotation of the bending head 21 when the pipe is bent, and then control the rotation of the driving component 211 through the controller 3 on the fixed frame 1 to realize the bending process of the pipe at the corresponding angle. The addition of the dial 4 can further improve the accuracy of the bending angle of the pipe and the uniformity of the bending angle of batch pipes.

[0029] The fixing frame 1 is provided with a detachable structure, including two upper and lower groups of first fixing plates 11 and second fixing plates 12 connected by multiple groups of connecting pipes 13, the elbow assembly 2 is installed on the first fixing plate 11 and the driving component 211 is placed below the first fixing plate 11 and above the second fixing plate 12. Figure 1 and Figure 4 It can be seen that the fixing frame 1 structure adopting such a detachable structure can be detachably connected through multiple sets of connecting pipes 13 inserted between the first fixing plate 11 and the second fixing plate 12. On the one hand, it is convenient for the installation and adjustment process of the driving component 211 and plays a certain protective role for the driving component 211. On the other hand, it is also convenient for installation and use, and can effectively reduce the weight of the bending device itself, making it convenient to carry and move.

[0030] The bottom of the second fixing plate 12 is also provided with a plurality of supporting feet 121, and the bottom of the supporting feet 121 is also pasted with a second anti-slip pad 122 of an appropriate size. Figure 4 As shown, the arrangement of multiple groups of supporting legs 121 at the bottom of the second fixing plate 12 facilitates use and support, reduces unnecessary wear caused by the second fixing plate 12 directly contacting the ground, and at the same time, the addition of second anti-slip pads 122 at the bottom of the supporting legs 121 can further increase the friction with the ground and have a certain shock-absorbing effect, thereby improving the stability of the pipe bending process of this pipe bending device at the corresponding use position.

Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
