The application method and the working principle of the device are as follows: when it is required to weld metal frames using the frame molding automatic production line in the metal working shop, firstly, a plurality of metal pipes are placed inside a plurality of limiting holes 302, wherein the outer diameters of the plurality of metal pipes are matched with the widths of the limiting holes 302, then an air pump 317 is started to drive a communicating pipe 318 to extract air into a fixed tank 315, wherein inert gas nitrogen is placed inside the fixed tank 315, the air enters the inside of a drainage pipe 319 through the communicating pipe 318, finally enters the inside of a sealing box 306, then a first electric telescopic rod 313 is started to extend, The first piston 314 is driven to move forwards, so that the sealing space inside the sealing box 306 is reduced, the gas inside the sealing box 306 is compressed, when the pressure sensor 307 detects that the pressure inside the sealing box 306 reaches the pressure capable of pushing the metal tube into the arc-shaped groove 304 in the welding frame 303, the two first electric push rods 309 are started to shorten, the two

polymer chains, has the characteristics of being stretchable and rebounded, when the rubber is compressed or deformed, the molecular chains can be deformed and can be restored to the original state after the external force is eliminated, the elastic characteristic enables the rubber to be tightly attached to the surface of other objects to form an effective seal, the pressure sensor 307 is a device for measuring the pressure, the working principle is based on the mechanical property of an elastic element, the sensor senses the external pressure applied by the elastic element, the shape of

sealing blocks 311, the air in the sealing box 306 continues to be conveyed forwards, the air is compressed again through the plurality of nozzles 321, and then the air is sprayed outwards, so that the metal pipe arranged at the bottommost part of the plurality of limit holes 302 is conveyed forwards under the pushing of external strong pressure through the sliding holes 320, and finally enters the inside of the plurality of arc grooves 304 respectively, wherein the nozzles 321 are a device for converting fluid into jet flow, high-speed jet flow is generated by accelerating the fluid in the inside of the nozzles 321, This type of nozzle 321 consists of a relatively high-tightness throat and a relatively large outlet, the velocity of the fluid increases as the liquid or gas flows through the nozzle 321 due to the reduction of the throat, which increases in accordance with the principle of continuity, which correspondingly reduces the flow rate of the fluid, and the mass per unit of fluid is equal at the throat and the outlet of the nozzle 321 according to the principle of conservation of mass, so that the density of the fluid decreases while the velocity increases, so that the

through the automatic feeding assembly 3, wherein, as shown in fig. 2-3, one ends of the circular grooves 305 and the arc-shaped grooves 304 are closed, in order to prevent the metal tube from moving out of the inside of the welding frame 303, The addition of metal materials in different directions in the automatic frame forming production line is facilitated by the action of the rotating assembly 4, after the addition of the metal pipe is completed, the welding head 507 is started, wherein the welding head 507 is also called a welding gun or a welding hand gun, is one of key tools in the welding process, the welding head 507 is connected to a power supply and a welding circuit, a required electric arc and an electric arc conduction state can be formed near the welding head 507 by
