[0030] Three groups of air holes are equidistantly arranged on the cylinder wall of the external cylinder 87; the inner side of the external air rings 88 is inserted with a plug rod and fixedly inserted with the external cylinder 87; the inner side of the air holes of the external cylinder 87 is fixedly inserted with a first rubber column 881; the first rubber column 881 is fixedly arranged on the outer arc surface of a first extrusion arc plate 882; and the inner arc surface of the first extrusion arc plate 882 is fixedly arranged with an external liquid bag 883.

[0031] The built-in component 89 comprises a built-in cylinder 891 fixedly installed on the side of the rotating base plate 86; the rotating joint 85 is fixedly installed on the side of the built-in cylinder 891, and the second rubber column 892 is slidingly arranged in the air hole of the cylinder wall of the built-in cylinder 891; the second rubber column 892 is fixedly installed on the inner arc surface of the second extrusion arc plate 893, and the inner liquid bag 894 is fixedly arranged on the outer arc surface of the second extrusion arc plate 893.

[0033] Based on the working principle of the automatic punching and necking machine described above is: First, when using the device, first place the device in the working area, then connect the device with the external power supply, and the device can provide the power required for work; Second, first place the liquid guide pipe 10 in the pipe positioning assembly 4, and connect the liquid guide pipe 10 with the necking assembly 8 under the cooperation of the X-axis displacement assembly 6 and the Y-axis displacement assembly 7, and connect the liquid guide pipe 10 with the external heat exchange equipment through the valve and pipeline arranged on the bottom side of the liquid guide pipe 10; Because the pipe head on both sides of the liquid guide pipe 10 is a standard gear for processing, the side pipe head of the liquid guide pipe 10 is extruded by the outer liquid bag 883 and the inner liquid bag 894, and then the gas is pressed into the outer gas ring 88 and the inner cylinder 891 through the rotating joint 85 to increase the pressure, and then the first rubber column 881 and the second rubber column 892 are pushed by the gas pressure to push the first extrusion arc plate 882 and the second extrusion arc plate 893 to extrude the outer liquid bag 883 and the inner liquid bag 894, and then the heat exchange liquid is introduced into the liquid guide pipe 10 through the valve and pipeline arranged on the bottom side of the liquid guide pipe 10 to exchange heat with the outer liquid bag 883 and the inner liquid bag 894, so that the temperature of the phase change material in the outer liquid bag 883 and the inner liquid bag 894 first rises and then falls, realizing that the outer liquid bag 883 and the inner liquid bag 894 can be tightly attached to the side pipe head of the liquid guide pipe 10, realizing the uniform and controllable radial force and intelligent heat management in the necking process. Third, the pipe to be processed is sent into the equipment in sequence through the feeding machine 2 on the left side of the frame body 1, and is conveyed from the left side to the working area on the right side through the belt driving assembly 41, and the blocking assembly 3 performs preliminary guiding and arrangement on the pipe to ensure that it enters the processing area in order; when the pipe is conveyed to the front of the blocking assembly 47, the sensor on the displacement frame 46 and the positioning sensor 91 perform position sensing, the conveying is paused, and accurate positioning is performed; after the single-body controller 472 receives the pipe-in-position signal, the second C-shaped coil ring 477 is powered to generate a strong magnetic field; at the same time, the first C-shaped coil ring 473 is powered to generate a magnetic field to drive the cast iron plate 474 to move rapidly to the opening side of the coil ring, since the cast iron plate 474 is fixed with the connected sleeve shaft 475, the connected sleeve shaft 475 is driven to rotate to make the turnover plates 476 fixed at both ends thereof stand up rapidly, accurately stop, and be adsorbed and positioned by the magnetic field of the second C-shaped coil ring 477; then, the driving motor 43 drives the lead screw 44, and under the special design of the electromagnetic sleeve ring 45, the outer ring of the electromagnetic sleeve ring 45 can generate a magnetic field after being powered, locking the screw hole sleeve and the displacement frame 46 inside, so that the rotating lead screw displacement frame 46 interacts with the fixed electromagnetic sleeve ring 45 to convert into linear motion, thereby pushing the entire displacement frame 46 and the blocking assembly 47 thereon to move synchronously to the right along the fixed frame 42, and accurately pushing the pipe to the processing station below the necking assembly 8; under the cooperation of the fine adjustment actions of the X-axis displacement assembly 6 and the Y-axis displacement assembly 7, the axis of the necking disc 9 is completely centered with the axis of the pipe; the driving of the control servo motor 82 starts to drive the driving gear 83 to drive the gear disc 84 and the rotating base plate 86 to rotate synchronously; the external cylinder 87 and the internal assembly 89 fixed on the rotating base plate 86 rotate together, and the end of the pipe is subjected to spinning and necking or punching through the displacement adjustment of the X-axis displacement assembly 6. Fourth, when it is necessary to release the pipe, the single-body controller cuts off the current of the first C-shaped coil ring, and the magnetic field disappears; at the same time, the second C-shaped coil ring 477 is powered, and the reverse magnetic field or pulling force generated thereby will assist the turnover plate to reset and fall down quickly according to the winding direction, and the blocking of the pipe is released; then, the Y-axis displacement assembly 7 drives the necking assembly 8 and the necking disc 9 to reset, preparing for the next working cycle, and the processed pipe is conveyed to the next process by the belt driving assembly 41.

[0034] The application provides an automatic punching and necking machine by improvement, full-automatic conveying and accurate positioning of the pipe are realized by integrating the feeding machine 2, the belt transmission assembly 41, the material blocking assembly 3 and the blocking assembly 47, wherein the blocking assembly 47 adopts the electromagnetic driving principle, the standing and stopping of the turnover plate and the resetting and releasing are quickly realized through the alternate power supply of the first C-shaped coil ring and the second C-shaped coil ring, the stable positioning of the pipe is ensured by combining the magnetic field adsorption; during the necking process, the X-axis displacement assembly 6 and the Y-axis displacement assembly 7 and the necking assembly 8 are cooperatively controlled, the necking disc 9 and the pipe axis are accurately centered, the external air ring 88 and the built-in cylinder 891 are used to push the rubber column to extrude the liquid capsule and the heat exchange liquid circulation system, the radial force uniform control and intelligent heat management in the pipe end spinning necking or punching process are realized, and the machining precision and process consistency are effectively improved.
