[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 3 A forming die for auxiliary stamping parts of a pipe cutting machine includes a pipe bending table 1. A fixing plate 2 is fixedly connected to the middle position of the upper surface of the pipe bending table 1. One end of the fixing plate 2 is arc-shaped and located in the middle position of the pipe bending table 1. A pipe bending assembly 3 is connected to the middle end of the fixing plate 2 in the pipe bending table 1. A side pressure assembly 4 is connected to the side wall of the pipe bending table 1 away from the pipe bending assembly 3. A downward pressure assembly 5 is connected to the top of the pipe bending table 1. The downward pressure assembly 5 is located on the side of the side pressure assembly 4 close to the pipe bending assembly 3.

[0021] like Figures 1 to 3 As shown, the main improvement of this utility model lies in its ability to adapt to pipe bending processes of different diameters, thereby improving the applicability of the pipe bending mold. Figures 1 to 3As shown, the forming mold for auxiliary stamping parts of the pipe cutting machine in this utility model, when in use, places the straight pipe to be bent between the fixed plate 2 and the side pressure component 4. After adjusting the bending position of the straight pipe, the side pressure component 4 presses the straight pipe against the side of the fixed plate 2. Then, the downward pressure component 5 presses the straight pipe downward onto the bending table 1. At this time, the bending component 3 can be adjusted, and the bending component 3, in conjunction with the arc end of the fixed plate 2, bends the end of the straight pipe. This allows for bending of straight pipes of different diameters, improving the applicability and processing range of the forming mold for bending, and indirectly reducing the purchase cost of pipe bending equipment for enterprises.

[0022] like Figures 1 to 3 As shown, the pipe bending assembly 3 includes a U-shaped frame 31 and a pipe bending motor 32. One end of the U-shaped frame 31 is rotatably connected to the bottom of the pipe bending table 1 via a rotating shaft, and the other end of the U-shaped frame 31 is rotatably connected to the side of the fixed plate 2 away from the pipe bending table 1 via a rotating shaft. The pipe bending motor 32 is fixedly connected to the bottom of the pipe bending table 1 via a motor base. The output shaft of the pipe bending motor 32 is fixedly connected to the end of the U-shaped frame 31 located at the bottom of the pipe bending table 1. The output shaft of the pipe bending motor 32 and the rotating shaft are located on the same axis. A pipe pressing assembly 6 is connected to the inner side of the U-shaped frame 31. During pipe bending, the pipe pressing assembly 6 is adjusted to press the end surface of the straight pipe against the end of the fixed plate 2. Then, the pipe bending motor 32 drives the U-shaped frame 31 to rotate around the rotating shaft at the bottom of the pipe bending table 1, so that while the pipe pressing assembly 6 rotates in a circle around the rotating shaft, the end of the straight pipe is gradually pressed and bent, thereby completing the pipe bending operation.

[0023] like Figures 1 to 3 As shown, the pipe pressing assembly 6 includes a pipe bending telescopic component 61 and a pipe bending plate 62. The pipe bending telescopic component 61 is fixedly connected to the U-shaped frame 31, and the telescopic end of the pipe bending telescopic component 61 faces the rotation axis of the U-shaped frame 31 and is fixedly connected to the pipe bending plate 62. The pipe bending telescopic component 61 can push the pipe bending plate 62 to press against the outside of the straight pipe on the pipe bending table 1, thereby adapting to the pipe diameter of the workpiece so as to perform pipe bending processing on straight pipes of different diameters. The pipe bending telescopic component 61 can use a hydraulic cylinder to ensure that during the pipe bending process, the relative position of the pipe bending plate 62 will not shrink during the mutual pressing between the pipe bending plate 62 and the surface of the straight pipe, thereby improving the stability and bending effect of the pipe bending process.

[0024] like Figures 1 to 3As shown, a mounting block 7 is fixedly connected to the end of the U-shaped frame 31 away from the bending motor 32 and the side away from the side pressure component 4. An auxiliary telescopic component 71 is fixedly connected to the side of the mounting block 7 away from the bending table 1. The output shaft of the auxiliary telescopic component 71 passes through the mounting block 7 and is fixedly connected to the bending auxiliary plate 72. Before bending, the bending auxiliary plate 72 can be moved downward by the auxiliary telescopic component 71, thereby pressing the end of the straight pipe to be bent downward onto the bending table 1. During the rotation of the U-shaped frame 31 and the bending process, the bending auxiliary plate 72 always presses down on the end of the bent pipe, thereby preventing the bend from tilting upward during the bending process and improving the stability and safety of the bending process. The auxiliary telescopic component 71 can be an electric push rod, a cylinder, or a hydraulic cylinder, etc., to prevent the end of the bent pipe from tilting upward.

[0025] like Figures 1 to 3 As shown, the side pressure assembly 4 includes a side pressure plate 41 and four connecting blocks 42. The four connecting blocks 42 are fixedly connected to the upper and lower ends of the side pressure plate 41, respectively. Two sliding grooves 101 are opened through the side of the bending platform 1 near the side pressure plate 41. The two connecting blocks 42 located below the side pressure plate 41 are slidably connected to the two sliding grooves 101, respectively. The side pressure telescopic members 43 are connected to the side of the four connecting blocks 42 near the fixed plate 2. The telescopic ends of the four side pressure telescopic members 43 are fixedly connected to the four connecting blocks 42, respectively. The two side pressure telescopic members 43 located above the side pressure plate 41 are fixedly connected to the top of the fixed plate 2, and the two side pressure telescopic members 43 located below the side pressure plate 41 are fixedly connected to the bottom of the bending platform 1. When the straight pipe to be bent is pressed against the side, the four side-pressing telescopic components 43 are activated simultaneously. The four connecting blocks 42 drive the side-pressing plate 41 to move smoothly towards the fixed plate 2, thus pressing the straight pipe against the side of the fixed plate 2. This prevents the end of the straight pipe from shaking due to the reaction force during bending. During this process, the two bottom connecting blocks 42 slide within the two sliding grooves 101. The telescopic movement of the four side-pressing telescopic components 43 must always be consistent to ensure that the side-pressing plate 41 presses smoothly against the outside of the straight pipe. The side-pressing telescopic components 43 can be hydraulic cylinders to provide a stable and constant pressure on the straight pipe, which avoids squeezing damage to the straight pipe and ensures that the straight pipe does not shake on one side of the fixed plate 2.

[0026] like Figures 1 to 3As shown, the pressing assembly 5 includes an L-shaped frame 51, a pressing telescopic component 52, and a pressing plate 53. One end of the L-shaped frame 51 is fixedly connected to one side of the bending table 1, and the other end is fixedly connected to the top of the fixing plate 2. The pressing telescopic component 52 is fixedly connected to the side of the L-shaped frame 51 away from the bending table 1. The telescopic end of the pressing telescopic component 52 passes through the L-shaped frame 51 and is fixedly connected to the pressing plate 53. The pressing plate 53 is located above the bending table 1 and is parallel to the bending table 1. The pressing telescopic component 52 drives the pressing plate 53 to gradually move downward from the top of the L-shaped frame 51, and presses the straight pipe close to the bending processing end downward. This, together with the side pressing assembly 4, forms a closed pressing, thereby ensuring that the straight pipe does not sway left and right or up and down on the bending table 1 during the bending process, improving the stability of the bending process. The pressing telescopic component 52 can be an electric push rod or a hydraulic cylinder, as long as the pressed straight pipe does not sway up and down.

[0027] like Figures 1 to 3 As shown, several support legs 8 are fixedly connected to the bottom of the bending table 1, and the support legs 8 are all located on the side of the U-shaped frame 31 near the side pressure component 4. The support legs 8 are used to support the bending table 1, and the support legs 8 located at the rear end of the rotation range of the U-shaped frame 31 do not obstruct or interfere with the rotation bending operation of the U-shaped frame 31.

[0028] 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.
