[0002] A reducing pipe refers to a pipe in which pipe segments with different diameters are connected in series in sequence, and its pressure loss is equal to the sum of the pressure losses of each pipe segment. It is commonly used in occasions with multiple branch pipes along the way. There are many processing methods for reducing pipes. Among them, there is a method of realizing different inner diameters at both ends of a round pipe by extruding the inner diameter of the round pipe. In order to manufacture reducing pipes, a variety of manufacturing devices for high-precision variable-diameter round pipes have been produced on the market.

[0003] In the existing manufacturing devices for high-precision variable-diameter round pipes, the subsequent round pipes to be processed cannot be prepared in advance during the process of processing the variable-diameter round pipes, resulting in placing the round pipes to be processed in the placement groove only after each round pipe is processed. Time cannot be fully utilized, affecting work efficiency. At the same time, when processing the round pipes with different degrees of variable diameters, due to the overly single processing workpiece, it is necessary to replace the equipment, and the round pipes cannot be processed with different diameters, with great limitations.

[0021] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners:

[0022] As Figures 1-5 shown, the present utility model provides a manufacturing device for high-precision variable-diameter circular pipes, including a bearing plate 1. A number of support frames 2 and a cabinet 6 are fixedly installed on the top of the bearing plate 1. A stamping mechanism 7 is arranged on the top of the cabinet 6. The stamping mechanism 7 includes a motor 701, a number of cylinders 704 and a number of stamping rods 706 with different diameters. The motor 701 drives the number of stamping rods 706 to rotate simultaneously through the number of cylinders 704. A single cylinder 704 can drive two stamping rods 706 to move vertically downward. One end of the number of support frames 2 is fixedly installed with a guide rail 3. A feeding mechanism 4 is arranged inside the guide rail 3. The feeding mechanism 4 includes a support base 401, two bottom plates 405 and two top plates 406. Pipe placing grooves 407 with the same diameter are formed on both the bottom plates 405 and the top plates 406. A moving mechanism 5 is arranged between the guide rail 3 and the support base 401. The moving mechanism 5 drives the two bottom plates 405 and the top plates 406 to move horizontally through the support base 401.

[0023] Before processing the diameter change of the circular tube, the staff first place several circular tubes in several corresponding tube placement grooves 407 respectively, and then start one of the cylinders 704. After the cylinder 704 runs, the output end of the cylinder 704 pushes the two connected punching rods 706 to move, so that the two punching rods 706 enter the circular tube. Then, after entering the circular tube for a certain distance, the inner wall of the circular tube is extruded, causing the inner wall of the circular tube to expand outwards, thus realizing the diameter change processing. If it is necessary to change the diameter of the circular tube diameter change processing, the staff first starts the motor 701. When the output end of the motor 701 rotates, it drives several cylinders 704 to rotate. As a result, several cylinders 704 can adjust their own positions in the rotating state, thereby adjusting the positions of several punching rods 706, replacing the used punching rods 706, so that the replaced punching rods 706 can process variable diameter tubes with different diameters after punching the circular tube. The replacement method is simple, and there is no need to replace the equipment when processing variable diameter tubes with different diameter requirements, reducing the operation procedures and time, and effectively improving the applicability and work efficiency;

[0024] After the first batch of circular tubes are processed, start the moving mechanism 5 to push the support base 401 to slide in the guide rail 3. When the support base 401 moves, it drives the two bottom plates 405 and the top plate 406 to move through two fixing plates 402, two connecting plates 403 and several locking plates 408, so that the circular tubes in several tube placement grooves 407 can move a certain distance. Then, when processing another two circular tubes, the staff can take out the processed circular tubes and place the circular tubes to be processed during this time. Randomly when the output end of the electric cylinder 501 retracts, it can continuously replace the positions of several tube placement grooves 407, make full use of the time for circular tube processing to pick up and place the remaining circular tubes, reduce the intermittent time of equipment processing, and further improve the work efficiency.

[0025] As Figure 4 shown, in one embodiment, the punching mechanism 7 further includes a rotating shaft 702, a rotating disk 703 and several docking plates 705. The motor 701 is fixedly installed on the top of the cabinet 6. The two ends of the rotating shaft 702 are fixedly connected to the output end of the motor 701 and the rotating disk 703 respectively. Several cylinders 704 are all fixedly connected to the rotating disk 703. Several docking plates 705 are respectively fixedly connected to the output ends of several cylinders 704. Several punching rods 706 are respectively threadedly connected to the bottoms of several docking plates 705.

[0026] By threadedly connecting the punching rod 706 with the docking plate 705, the punching rod 706 can be quickly removed when replacing the punching rod 706, improving the replacement efficiency.

[0027] As Figure 2As shown, in one embodiment, the feeding mechanism 4 further includes two connecting plates 403, two fixing plates 402, and a plurality of locking plates 408. The support base 401 is slidably engaged with the guide rail 3. The two fixing plates 402 are both fixedly connected to the top of the support base 401. The two connecting plates 403 are respectively fixedly connected to the two fixing plates 402. The two bottom plates 405 are respectively fixedly connected to the tops of the two connecting plates 403. The two top plates 406 are respectively fixedly connected to the bottom plates 405 through the plurality of locking plates 408.

[0028] The plurality of locking plates 408 are all used to fix the top plate 406 and the bottom plate 405, improving the structural stability. When the support base 401 moves, the two bottom plates 405 and the top plate 406 are driven to move through the two fixing plates 402, the two connecting plates 403, and the plurality of locking plates 408. As a result, the round tubes in the plurality of pipe placing grooves 407 can move a certain distance, making full use of the time for replacing the round tubes to process other round tubes and improving the working efficiency.

[0029] As Figure 1 and Figure 3 As shown, in one embodiment, the moving mechanism 5 includes an electric cylinder 501, a Z-shaped plate 502, and a fixing block 503. The fixing block 503 is fixedly installed at one end of the guide rail 3. The electric cylinder 501 is fixedly installed at one end of the fixing block 503. One end of the fixing block 503 is fixedly connected to the output end of the electric cylinder 501, and the other end is fixedly connected to the support base 401.

[0030] The electric cylinder 501, when the output end of the electric cylinder 501 is extended, pushes the Z-shaped plate 502 to move horizontally. When the Z-shaped plate 502 moves, it pushes the support base 401 to slide in the guide rail 3. By setting the Z-shaped plate 502, the structure of the device is concentrated, which can effectively reduce the occupied area of the device and further improve the applicability.

[0031] As Figure 5 As shown, in one embodiment, a protective cover 8 is fixedly installed on the top of the cabinet 6, and a control panel 9 is fixedly installed at one end of the cabinet 6.

[0032] The protective cover 8 is used to protect the motor 701, improving the protection effect of the motor 701. The control panel 9 can facilitate the operation of the staff, reducing the operation difficulty and further improving the applicability.

[0033] Next, specifically describe the working principle of the manufacturing device for high-precision round tube diameter variation:

[0034] Before processing the diameter change of the circular tube, the staff first place several circular tubes in several corresponding tube placement grooves 407 respectively, and then start one of the cylinders 704 through the control panel 9. The output end of the operated cylinder 704 pushes the connected docking plate 705 to move vertically downward. When the docking plate 705 moves, it drives two stamping rods 706 to move, so that the two stamping rods 706 enter the circular tube. Then, after entering the circular tube for a certain distance, the inner wall of the circular tube is extruded, causing the inner wall of the circular tube to expand outward, thereby realizing the diameter change processing. If it is necessary to change the diameter of the circular tube for diameter change processing, the staff first start the motor 701. When the output end of the motor 701 rotates, it first drives the rotating shaft 702 to rotate. When the rotating shaft 702 rotates, it drives the rotating disk 703 to rotate. When the rotating disk 703 rotates, it drives several cylinders 704 to rotate, so that several cylinders 704 can adjust their own positions in the rotating state, thereby adjusting the positions of several stamping rods 706, replacing the used stamping rods 706, so that the replaced stamping rods 706 can process variable-diameter tubes with different diameters after stamping the circular tube. The replacement method is simple, and there is no need to replace the equipment when processing variable-diameter tubes with different diameter requirements, reducing the operation procedures and time, and effectively improving the applicability and work efficiency;

[0035] After the processing of the first batch of circular tubes is completed, start the electric cylinder 501. After the output end of the electric cylinder 501 is pushed out, it pushes the Z-shaped plate 502 to move horizontally. When the Z-shaped plate 502 moves, it pushes the support base 401 to slide in the guide rail 3. When the support base 401 moves, it drives the two bottom plates 405 and the top plate 406 to move through two fixing plates 402, two connecting plates 403 and several locking plates 408, so that the circular tubes in several tube placement grooves 407 can move a certain distance. Then, when processing another two circular tubes, the staff can take out the processed circular tubes and place the circular tubes to be processed during this time. Randomly, when the output end of the electric cylinder 501 retracts, the positions of several tube placement grooves 407 can be continuously replaced, making full use of the time for circular tube processing to pick up and place the remaining circular tubes, reducing the intermittent time of equipment processing, and further improving the work efficiency.

[0036] The above text generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements that do not depart from the spirit of the present invention are all within the protection scope of the present invention.
