Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A pipe bending machine device for quick mold changing includes a machine base 1, a mating baffle 3, and an auxiliary pipe bending structure 4. A bending drive assembly 5 is fixedly connected to the front end of the machine base 1. A lower mold assembly 6 is fixedly connected to one side of the bending drive assembly 5. An upper wheel mold assembly 7 is installed inside the lower mold assembly 6. The lower mold assembly 6 includes a mold box 61. A rail groove 62 is opened inside the mold box 61. A first toothed plate 63 and a spring 64 are fixedly connected inside the rail groove 62. A guide rail plate 66 is slidably connected inside the rail groove 62. A lower mold body 65 is fixedly connected to one side of the guide rail plate 66. A slot 67 is opened inside the lower mold body 65. A second toothed plate 68 is fixedly connected to the left side of the slot 67. The upper wheel mold assembly 7 includes an insert rod 71. A metal friction block 72 is fixedly connected to the outside of the insert rod 71. A pipe bending wheel mold 73 is rotatably connected to the upper end of the insert rod 71. The insert rod 71 and the metal friction block 72 are inserted into the inside of the slot 67.

[0030] As a further implementation of this solution, the bending drive assembly 5 includes a drive motor 51, a folding plate 52 fixedly connected to the end of the main shaft of the drive motor 51, a hydraulic rod 53 fixedly connected to the upper end of the folding plate 52, the right side of the hydraulic rod 53 fixedly connected to the left side of the mold box 61, and the bottom end of the housing of the drive motor 51 fixedly connected to one side of the machine base 1. With the above settings, the drive motor 51 can drive the lower mold assembly 6 and the upper wheel mold assembly 7 as a whole to assist the rotation of the axis of the bending wheel mold 73 on the bending structure 4, thereby achieving the effect of bending the pipe.

[0031] As a further implementation of this solution, an electric telescopic rod 2 is fixedly connected to the upper end of the machine base 1, and a base plate is fixedly connected to the front end of the machine base 1. The machine base 1 is fixedly connected to the bottom end of the auxiliary bending structure 4 through the base plate. One side of the electric telescopic rod 2 is fixedly connected to the left side of the mating baffle 3. A dovetail groove is opened at the upper end of the machine base 1, and a dovetail slider is fixedly connected to the bottom end of the mating baffle 3. The mating baffle 3 and the machine base 1 are slidably connected. With the above settings, the electric telescopic rod 2 pushes the mating baffle 3 to move. When the pipe between the bending molds 73 moves with the bending molds 73, the mating baffle 3 moves the same distance at the same time. The bending effect of the pipe can be achieved by the partition of the mating baffle 3 and the cooperation of the auxiliary bending structure 4.

[0032] As a further implementation of this solution, the bending drive assembly 5 is located at the lower end of the auxiliary bending structure 4. The structure of the auxiliary bending structure 4 is the same as that of the upper wheel die assembly 7 plus the lower die assembly 6. The top of the auxiliary bending structure 4, the top of the upper wheel die assembly 7 and the top of the mating baffle 3 are flush. With the above settings, the pipe will not tilt upward or downward when bending, thus ensuring the bending quality of the pipe.

[0033] As a further implementation of this scheme, the rail groove 62 penetrates the upper end of the mold box 61, the spring 64 is distributed at the upper and lower ends of the first toothed plate 63, the right end of the spring 64 is fixedly connected to the left side of the lower mold body 65, the second toothed plate 68 is aligned with the first toothed plate 63, the lower mold body 65 is embedded in the inner side of the rail groove 62, the slot 67 penetrates the upper end of the lower mold body 65, the insert rod 71 protrudes from the upper end of the lower mold body 65, the insert rod 71 and the metal friction block 72 are evenly attached to the inner side of the lower mold body 65, and the bending wheel mold 73 protrudes from the left end of the mold box 61. Through the above settings, the elastic design of the spring 64 and the embedded installation of the lower mold body 65 enhance the buffering and reset capabilities of the device, improve the friction, and prevent the insert rod 71 from disengaging from the lower mold body 65 during bending, thus ensuring the stability of the mold during the bending process.

[0034] Workflow: When bending the pipe, place the part of the pipe to be bent between the bending die 73 on the insert rod 71 and the bending die 73 on the auxiliary bending structure 4. Activate the hydraulic rod 53 to move the lower die assembly 6 and the upper die assembly 7 towards the auxiliary bending structure 4. Simultaneously, activate the electric telescopic rod 2 to push the mating baffle 3, which in turn moves the rear end of the pipe. The mating baffle 3 slides on the upper part of the machine base 1, limiting its movement. When both bending dies 73 are in contact with the pipe, under pressure, the bending die 73, insert rod 71, and metal friction block 72 move to the left. The insert rod 71 and metal friction block 72 move the tightly attached spring 64 to the left. The lower die body 65, limited by the guide rail plate 66 sliding within the rail groove 62, moves to the left, pressing against the spring 64. The spring 64 buffers and resets the lower die body 65. Meanwhile, the elastic force of the spring 64 can increase the friction between the lower die body 65 and the insert rod 71 and the metal friction block 72. When the second toothed plate 68 meshes with the first toothed plate 63, the hydraulic rod 53 can be stopped. When the second toothed plate 68 and the first toothed plate 63 inside the lower die assembly 6, the upper wheel die assembly 7 and the auxiliary bending structure 4 mesh, it can prevent the lower die body 65 from twisting inside the die box 61 during bending. After the upper wheel die assembly 7 moves to the auxiliary bending structure 4 to a certain distance and can no longer move, the friction between the insert rod 71, the metal friction block 72 and the lower die body 65 reaches its maximum value, which can prevent the insert rod 71 from disengaging from the slot 67 during bending. The drive motor 51 is started to drive the bending plate 52, the hydraulic rod 53, the lower die assembly 6 and the upper wheel die assembly 7 to rotate as a whole. Through the bending wheel die 73 at the left end, the effect of bending the pipe is achieved. At the same time, under the action of the pipe extrusion, the lower die body 65 inside the auxiliary bending structure 4 will not move.

[0035] When replacing the bending die 73 according to different pipe diameters, simply hold the bending die 73 by hand and pull it upwards. The metal friction block 72 will drive the insertion rod 71 and the metal friction block 72 to move out of the slot 67. For the specified model of bending die 73, align the metal friction block 72 with the slot 67 and directly place the insertion rod 71 and the metal friction block 72 into the slot 67 to complete the quick replacement of the bending die 73. This replacement method does not require the removal and installation of bolts, which greatly improves the efficiency of die replacement and ensures the stability of the die when processing pipes.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
