Description

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Reference Figure 1-Figure 5 The utility model provides an electron tube forming machine, comprising a workbench 1, on which a rolling mechanism, a heating mechanism and a cooling mechanism are sequentially arranged;

[0026] The cooling mechanism includes a water-cooling pipe 2 and an air blowing pipe 3. Both the water-cooling pipe 2 and the air blowing pipe 3 are hollow. The water-cooling pipe 2 is fixed to the workbench 1 and is sleeved on the air blowing pipe 3. The water-cooling pipe 2 and the air blowing pipe 3 are respectively provided with air vents 4 along the axial direction, and the two air vents 4 are arranged opposite each other. The inner wall of the air blowing pipe 3 is circumferentially provided with a plurality of air outlet holes 5. The air blowing pipe 3 is provided with an air supply assembly, which is connected to the plurality of air outlet holes 5. The inner diameter of the air blowing pipe 3 is larger than the diameter of the electron tube.

[0027] A water cooling cavity is formed in the wall of the water cooling pipe 2, and a water inlet and outlet assembly is provided on the water cooling pipe 2, which is connected to the water cooling cavity;

[0028] When in use, a tube strip (not shown in the figure) wound on the material shaft is provided at the front end of the rolling mechanism, and a stretching device (not shown in the figure) is provided at the rear end of the cooling mechanism, which is used to pull the electron tube after cooling and shaping, thereby providing power for the electron tube to move; when working, the tube strip on the material shaft is formed into a hollow tube by the rolling mechanism, heated and bonded by the heating mechanism, and then cooled and shaped by the cooling mechanism. When cooling, the electron tube passes through the blowing pipe 3, and the air supply component provides gas to be blown out through a plurality of air outlets 5. The air outlets 5 are arranged around the electron tube, so that the air volume is concentrated on the circumference of the electron tube for air cooling, reducing the air volume loss while improving the cooling efficiency and cooling effect. Then the gas is blown out through the two ends of the blowing pipe 3 and the air vent 4; while cooling, the water inlet and outlet components provide cooling water to enter the cold water chamber, reducing the temperature of the blowing pipe 3 and the electron tube, and further improving the cooling effect.

[0029] To further optimize the solution, an air cavity connected to a plurality of air outlet holes 5 is opened in the air blowing pipe 3, and the air supply assembly includes a plurality of air supply pipes 6. The air supply pipes 6 pass through the side wall of the water-cooling tube 2 and are fixedly connected to the air blowing pipe 3, and the air blowing pipe 3 is connected to the air cavity; when working, the air supply pipe 6 is connected to an air pump (not shown in the figure), and the air pump supplies gas to the air supply pipe 6. The gas enters the air cavity of the air blowing pipe 3 and is blown out through the air outlet holes 5, thereby circumferentially cooling the electron tube.

[0030] To further optimize the solution, the water inlet and outlet components include a water inlet pipe 7 and a water outlet pipe 8 fixedly connected to the side wall of the water-cooling tube 2. The water inlet pipe 7 and the water outlet pipe 8 are respectively located on both sides of the water-cooling tube 2, and the water inlet pipe 7 and the water outlet pipe 8 are respectively connected to the water-cooling cavity; a serpentine channel is provided in the water-cooling cavity in the water-cooling tube 2, and the water inlet pipe 7 and the water outlet pipe 8 are respectively connected to the two ends of the serpentine channel, thereby improving the water cooling effect.

[0031] To further optimize the solution, the heating mechanism includes an electric heating tube 9 with a hollow structure, which is fixed to the workbench 1. A heat-conducting mold tube 10 is provided inside the electric heating tube 9. A mold channel 11 is provided on the heat-conducting mold tube 10. The mold channel 11 is coaxially arranged with the water-cooling tube 2.

[0032] According to a further optimized solution, the mold channel 11 is tapered, and the small diameter end of the mold channel 11 is close to the water cooling pipe 2 .

[0033] An electric heating wire is embedded in the electric heating tube 9, and the outer wall of the electric heating tube 9 is wrapped with an insulation layer. When in use, the electron tube passes through the mold channel 11 and is heated by the electric heating wire. The heat heats the electron tube in the mold channel 11 through the heat-conducting mold tube 10, so that the overlapping parts of the electron tubes are bonded together.

[0034] To further optimize the solution, the electric heating tube 9 includes two semicircular tubes, which are combined to form the electric heating tube 9. The two semicircular tubes are arranged up and down, and the semicircular tube located at the bottom is fixed on the workbench 1. The two semicircular tubes are detachably connected by a number of bolts 12.

[0035] A further optimized solution is provided, in which the rolling mechanism includes a conical tube 13 fixedly connected to the top of the workbench 1, the conical tube 13 is located at the end of the electric heating tube 9 away from the water-cooling tube 2, the small diameter end of the conical tube 13 is close to the electric heating tube 9, the conical tube 13 is coaxial with the mold channel 11, and an arc-shaped spacer 14 is fixedly connected to the inner wall of the conical tube 13, a gap is provided between the arc-shaped spacer 14 and the inner wall of the conical tube 13, and an arc-shaped transition zone is provided at the part where the arc-shaped spacer 14 is connected to the inner wall of the conical tube 13.

[0036] To further optimize the solution, a guide block 15 is fixedly connected to the workbench 1, and the guide block 15 is located at the end of the tapered tube 13 away from the electric heating tube 9. An arc groove 16 is provided on the top of the guide block 15, and a guide rod 17 is fixedly connected to the guide block 15. The guide rod 17 is located in the arc groove 16 and there is a gap between the guide rod 17 and the arc groove 16, and one end of the guide rod 17 extends into the tapered tube 13.

[0037] When the present invention is in use, the strip-shaped pipe first passes through the gap between the arc-shaped groove 16 and the guide rod 17 and fits against the inner wall of the arc-shaped groove 16, thereby causing the pipe to be initially bent into an arc shape;

[0038] The curved tube strip enters the conical tube 13, fits against the inner wall of the conical tube 13, and is gradually rolled into a hollow tube inside the conical tube 13. The two side edges of the tube strip are respectively located on the curved spacer 14 and on the inner wall of the conical tube 13 opposite the curved spacer 14, avoiding interference between the two sides.

[0039] After passing through the tapered tube 13, the tube strip becomes a hollow tube with overlapping parts on both sides. Then the tube strip enters the electric heating tube 9 for heating, so that the overlapping parts are bonded together to form an electron tube. After the electron tube is heated, it enters the blowing tube 3 for air cooling, and is cooled by the water cooling tube 2 to be shaped. After the shaping is completed, the electron tube enters the stretching device, which provides driving force for the movement of the tube strip.
