Working process: When the first contact switch 412 contacts the contact block 411, the first contact switch 412 controls the air pump 51 to start, and the air pump 51 absorbs the harmful gas generated during the welding process through the air inlet pipe 52. During this period, the filter 53 filters and purifies the harmful gas. The purified air discharged from the air inlet pipe 52 is discharged from the air outlet pipe 57 and divided into two, one of which enters the push rod cylinder 58. In the initial state, the solenoid valve 59 is in a closed state, and air is not allowed to pass through. Therefore, the push rod cylinder 58 is in a sealed state. After the air enters the push rod cylinder 58, the push rod 511 moves outward due to the action of air pressure. After moving a certain distance, the baffle 516 is connected to the second contact switch 5 17 contacts, the control solenoid valve 59 is opened, the push rod tube 58 will be in a sealed state, and the air is discharged from the blowing pipe 510. Under the action of the spring 515, the push rod 511 moves inward. After moving a certain distance, the baffle plate 516 contacts the third contact switch 518, the control solenoid valve 59 is closed, the push rod tube 58 will be in a sealed state again, and the push rod 511 will move outward again, that is, the push rod 511 will reciprocate.

The upper half of the push block is arranged on the loading platform The top outer wall of 61, the upper half of the push block can push the welding pipe body 45, the slide groove 410 includes a primary groove, a secondary groove, a tertiary groove and a quaternary groove, the primary groove is located near the unloading stop block 63, the secondary groove is located near the loading stop block 64, the tertiary groove is located near the grinding plate 512, and the quaternary groove is located near the welding head 44. The distances between the surfaces of the primary groove, the secondary groove, the tertiary groove and the quaternary groove relative to the rotating disk 43 decrease successively, and the primary groove, the secondary groove, the tertiary groove and the quaternary groove transition smoothly in sequence.

[0023] Working process: the welding pipe body 45 to be welded is neatly placed on the loading platform 61. When the first contact switch 412 contacts the contact block 411, the first contact switch 412 controls the electric push rod 65 to retract. The two electric push rods 65 drive the welding pipe body 45 on the loading platform 61 to move toward the corresponding pipe support rod 46 respectively. Under the friction between the welding pipe body 45 and the pipe support rod 46 and the blocking effect of the retaining ring 47, the relative position of the welding pipe body 45 and the pipe support rod 46 is fixed, that is, the loading is completed. When the cam divider 3 rotates, the contact block 411 and the first contact switch 412 are separated, and the electric push rod 65 extends out. The slider 49 moves along the slide groove 410 from the fourth-level groove to the first-level groove. The distance between the surface of the first-level groove and the rotating disk 43 becomes larger than that of the fourth-level groove. At this time, the sliders 49 at the same position on the two opposite annular bases 41 move away from each other, thereby driving the two corresponding pipe support rods 46 to move away from each other. Since the radius of the outer surface of the welding pipe body 45 is greater than the radius of the outer surface of the retaining ring 47, a height difference is formed between the outer surface of the welding pipe body 45 and the outer surface of the retaining ring 46 compared with the outer surface of the pipe support rod 46. In the process of the two corresponding pipe support rods 46 moving away from each other, the unloading stopper 63 utilizes the height difference to contact only the welding pipe body 45 but not the retaining ring 47 and the pipe support rod 46. At this time, the welding pipe body 45 will be blocked by the unloading stopper 63 and detached from the welding pipe body 45, and the unloading is completed.

[0025] Working process: The purified air discharged from the air inlet pipe 52 is discharged from the air outlet pipe 57 and divided into two, one of which enters the push rod tube 58, and the other enters the impeller cover 513. The air entering the impeller cover 513 blows the impeller 514 to rotate, and the rotation of the impeller 514 drives the knocking wheel 55 to rotate, and the knocking rubber strip 56 knocks the welded welding pipe body 45 to eliminate welding stress.

The cam divider 3 is started, and the cam divider 3 rotates intermittently every 90 degrees. When the cam divider 3 stops, the first contact switch 412 contacts the contact block 411. At this time: The first contact switch 412 controls the electric push rod 65 to retract, and the two electric push rods 65 drive the welding pipe body 45 on the loading platform 61 to move toward the corresponding pipe support rod 46 respectively, and the relative position of the welding pipe body 45 and the pipe support rod 46 is fixed under the friction between the welding pipe body 45 and the pipe support rod 46 and the blocking effect of the retaining ring 47, that is, the loading is completed; The first contact switch 412 controls the welding head 44 and the motor 48 to start, and the motor 48 drives the pipe support rod 46 to rotate, and then drives the welding pipe body 45 to rotate, so as to complete the surrounding integral welding of the welding pipe body 45; The first contact switch 412 controls the air pump 51 to start. The air pump 51 absorbs the harmful gas generated during the welding process through the air inlet pipe 52. During this period, the filter 53 filters and purifies the harmful gas. The purified air discharged from the air inlet pipe 52 is discharged from the air outlet pipe 57 and divided into two. One stream enters the push rod cylinder 58 and the other enters the impeller cover 513. In the initial state, the solenoid valve 59 is in a closed state.

After moving a certain distance, the baffle 516 contacts the second contact switch 517, controlling the solenoid valve 59 to open, and the air is discharged from the blowing pipe 510. The rod 511 moves inwards, and after moving a certain distance, the baffle plate 516 contacts the third contact switch 518, the control solenoid valve 59 is closed, and the push rod 511 moves outwards again, that is, the push rod 511 will make a reciprocating motion, at this time, the grinding plate 512 grinds the welding surface of the welding pipe body 45 to be welded to remove its surface impurities, and the impurities attached to the grinding plate 512 and the surface of the welding pipe body 45 will be blown away by the gas blown out of the blowing pipe 510, and the air entering the impeller cover 513 blows the impeller 514 to rotate, and the rotation of the impeller 514 drives the knocking wheel 55 to rotate, and the knocking rubber strip 56 knocks the welded welding pipe body 45 to eliminate welding stress; When the cam divider 3 rotates, the contact block 411 and the first contact switch 412 are separated, the welding head 44 is closed, the motor 48 is closed, the air pump 51 is closed, and the electric push rod 65 is extended.
