[0002] The corrugated sheet is made of folded plates. Each corrugated body is composed of two tightly attached plates. The gap between the two plates needs to be welded. In the early days of welding, it was done manually. Later, because the pollution caused by manual welding had a greater impact on the human body, the automatic welding machine for corrugated sheets was invented. However, the traditional corrugated sheet welding machine has a limited welding range and cannot be used in some specific welding occasions. Different manufacturers began to invent corrugated sheet welding machines suitable for themselves.

[0021] Example:

[0022] See also Figure 1-4 The present invention provides a technical solution: a welding machine for automatic welding of corrugated fins and round steel, comprising two welding boxes 15, a main support frame 1, two auxiliary support frames 7 and two inner support frames 11, wherein there is an auxiliary support frame 7 on the left and right sides of the main support frame 1, and there are two inner support frames 11 on the inner sides of the two auxiliary support frames 7, and there is a welding box 15 behind the two inner support frames 11, a cover plate 2 is installed in the middle part of the upper part of the main support frame 1, a pushing cylinder 3 is installed in front of the upper end face of the cover plate 2, linear guide rails 4 are installed on the left and right sides of the upper end face of the cover plate 2, and a sliding plate 5 is installed above the two linear guide rails 4, and the linear guide rails 4 limit the moving direction of the sliding plate 5 to prevent the sliding plate 5 from shaking during sliding, and the front of the sliding plate 5 is connected to the pushing cylinder 3, and the left and right sides of the lower surface of the sliding plate 5 are installed with push rods 6, and the push rods 6 can push the round steel to move;

[0023] A round steel storage box 8 is installed on the top of the two auxiliary support frames 7, and round steel can be stored in the round steel storage box 8. Two open grooves 81 are opened at the bottom of the box body of the two round steel storage boxes 8. Two pneumatic push rods 10 are installed under the two auxiliary support frames 7. Push plates 9 are installed on the top of the four pneumatic push rods 10. The four push plates 9 pass through the four open grooves 81 respectively. Three transition plates 19 are installed on the top of the two inner support frames 11, and the six transition plates 19 are connected to the round steel storage box 8. Round steel positioning grooves 18 are installed on the top of the two inner support frames 11. The two round steel positioning grooves 18 are respectively located directly below the two push rods 6, and the six transition plates 19 are connected to the round steel positioning grooves 18.

[0024] Fixed blocks 12 are installed on the front and back of the two inner support frames 11, and a connecting rod 16 is connected between the two fixed blocks 12 on the same side. Four baffles 17 are installed on the two connecting rods 16. When the baffle 17 contacts the round steel storage box 8, the empty space and part of the round steel storage box 8 can only store one round steel, avoiding the transportation of two round steels at a time. Two linkage plates 13 are installed on the two connecting rods 16, and the four linkage plates 13 are all on the outside of the baffle 17. Electric push rods 14 are installed on both sides of the front and back of the two inner support frames 11, and the four electric push rods 14 are connected to the linkage plates 13.

[0025] The two round steel positioning grooves 18 are in a V-shape, which can be positioned. When the round steel is in the round steel positioning groove 18, the round steel is on the extension line of the center of the semicircular groove of the welding box.

[0026] The thickness of the two push plates 9 is equal to the diameter of the round steel, and the upper end surfaces of the two push plates 9 are inclined end surfaces, so that the push plates 9 can only push out one round steel at a time.

[0027] The height difference between the V-shaped bottom of the two round steel positioning grooves 18 and the highest point of the round steel storage box 8 does not exceed 30 cm, so as to avoid the round steel from rushing out of the round steel positioning groove 18 due to the large kinetic energy obtained during rolling.

[0028] The worker puts the round steel into the round steel storage box 8, and the round steel rolls to the bottom of the round steel storage box 8 under the action of gravity, and starts the pneumatic push rod 10, which pushes the push plate 9, and the push plate 9 pushes out the round steel, and the baffle 17 clamps a pushed out round steel, closes the pneumatic push rod 10, and the pneumatic push rod 10 drives the push plate 9 to fall, opens the electric push rod 14, and the electric push rod 14 pushes the linkage plate 13, and the linkage plate 13 drives the linkage rod 16 to rotate, and the linkage rod 16 rotates to drive the baffle 17 to rotate, and the round steel rolls under the action of gravity, passes through the transition plate 19, and the round steel enters the round steel positioning groove 18. When the clamping teeth of the welding box 15 clamp the wave wing, start the pushing cylinder 3, and the pushing cylinder 3 pushes the sliding plate 5, and the sliding plate 5 drives the push rod 6, and the push rod 6 pushes the round steel in the round steel positioning groove 18. When the round steel passes through the welding box 15, the pressure plate of the welding box 15 presses the round steel downward, and the welding gun of the welding box 15 starts welding.
