[0019] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0020] Example 1 An automatic welding device for C-shaped steel processing, such as Figure 1-Figure 10 As shown, it includes a placement rack 1 and a welding vehicle 2; a placement slot is opened on the placement rack 1; and a welding vehicle 2 is arranged on the left side of the placement rack 1; It also includes a sliding frame 3, a sliding plate 4, a handle 5, a spring telescopic plate 6, a support plate 7, a battery-powered electric push rod 8 and a wedge block 9; a sliding frame 3 is arranged on the right side of the placement frame 1; a sliding plate 4 is slidably connected to the sliding frame 3; a handle 5 is welded to the right end of the sliding plate 4; a spring telescopic plate 6 is fixedly connected to the front and rear sides of the sliding plate 4 respectively; the telescopic ends of the two spring telescopic plates 6 are respectively fixedly connected to a support plate 7; a groove 701 is opened in the middle of the two support plates 7; a battery-powered electric push rod 8 is fixedly connected to the left and right sides of the sliding plate 4 respectively; the telescopic ends of the two battery-powered electric push rods 8 are respectively fixedly connected to a wedge block 9.

[0021] In order to facilitate insertion into the C-shaped steel, the lower left end of the sliding plate 4 is beveled.

[0022] In order to facilitate manual gripping and pushing, the outer surface of the handle 5 is roughened.

[0023] In order to facilitate the C-shaped steel to enter the groove 701 , an end of the groove 701 away from the sliding plate 4 is beveled.

[0024] The sliding frame 3 also includes a latch 10 ; the left side of the sliding frame 3 is fixedly connected with the latch 10 ; and the placement frame 1 is provided with a socket that matches the latch 10 .

[0025] In order to facilitate the insertion of the latch 10 into the insertion hole on the placement rack 1, the left end of the latch 10 is beveled.

[0026] The first step: manually place the placement rack 1 next to the C-shaped steel storage position, then place the welding vehicle 2 on the left side of the placement rack 1, and the sliding rack 3 on the right side of the placement rack 1, and insert the pin 10 on the left side of the sliding rack 3 into the socket on the placement rack 1, so that the sliding rack 3 is opposite to the placement rack 1; then, manually place a C-shaped steel with the opening facing upward on the placement slot of the placement rack 1, and then place another C-shaped steel with the opening facing downward on the C-shaped steel with the opening facing upward, so that the left and right sides of the two C-shaped steels are flush, so that the two C-shaped steels are initially stacked together, as shown in FIG. Figure 3 shown.

[0027] The second step: manually push the sliding plate 4 to slide to the left on the sliding frame 3 through the handle 5, and the sliding plate 4 drives the spring telescopic plate 6 and the support plate 7 to enter the cavity formed by the two C-shaped steels, and then simultaneously control the telescopic ends of the two power storage electric push rods 8 to retract, and the two power storage electric push rods 8 move toward each other with the two wedge blocks 9, and the two wedge blocks 9 move to contact the two support plates 7, and then the two wedge blocks 9 force the two support plates 7 to move back to each other and stretch the corresponding spring telescopic plates 6, so that the two support plates 7 are in contact with the inner front and inner rear sides of the two C-shaped steels, so that the inner front and inner rear sides of the two C-shaped steels are flush, and then the inner front and inner rear sides of the two C-shaped steels are flush, so that welding can be carried out smoothly; the inner front and inner rear sides of the two C-shaped steels are limited by the two support plates 7 to prevent the two C-shaped steels from shifting in the front and rear directions, and the contact between the two C-shaped steels will be stuck in the groove 701, so that the two C-shaped steels are close to each other for easy welding.

[0028] The third step: control the welding vehicle 2 to move to the right, so that the two welding guns on the welding vehicle 2 move to the contact point of the two C-shaped steels. Each time the welding guns on the welding vehicle 2 move one end, the welding guns on the welding vehicle 2 are controlled to automatically weld the two C-shaped steels once, so that multiple welds are formed at the contact point of the two C-shaped steels, and the welding of the two C-shaped steels is completed; after completion, the welding vehicle 2 is controlled to move to the left and reset, and then the telescopic ends of the two power storage electric push rods 8 are controlled to extend and reset, so that the two support plates 7 move back to back and reset to separate from the two C-shaped steels, and then the sliding plate 4 is manually pulled to slide to the right on the sliding frame 3 through the handle 5, and the sliding plate 4 drives the spring telescopic plate 6 and the support plate 7 to move out of the cavity formed by the two C-shaped steels, and finally the two C-shaped steels welded together are manually removed from the placement frame 1. ; The present invention can prevent the two C-shaped steels from shifting in the front and rear directions through two support plates 7, and the two C-shaped steels will be stuck in the groove 701 at the contact point between each other, so that the two C-shaped steels are close to each other, which is convenient for welding. It replaces the existing welding machine that uses multiple limiting wheels, limiting plates and pressure plates to achieve limiting operations, significantly reducing the size of the equipment, so that the equipment can be more easily moved to the construction site for welding operations, greatly improving its applicability and flexibility; there are many benefits to transporting the C-shaped steel welding equipment to the construction site for welding, such as: on-site welding can reduce the storage requirements for large prefabricated components and reduce storage costs; it can improve flexibility: on-site welding can quickly respond to emergencies, such as design changes, material shortages, etc., to ensure that the construction progress is not affected.

[0029] Example 2 On the basis of Example 1, Figure 7-Figure 9 As shown, it also includes a conductive plate 21 and an electric heating block 22; two conductive plates 21 are fixedly connected to the front and rear sides of the sliding plate 4, and the two conductive plates 21 on the same side are symmetrically arranged up and down; each conductive plate 21 is connected to five electric heating blocks 22 through wires, and the wires are in a curved shape; all the electric heating blocks 22 are fixedly connected to the support plate 7.

[0030] Preheating before welding is a process measure to appropriately heat the area around the weld before welding. Its purpose is to reduce the cooling rate of the weld and the surrounding area, avoid the formation of hardened structure and reduce welding stress and deformation. It is an effective method to prevent welding cracks. Therefore, an electric heating block 22 is arranged on the support plate 7. In the second step, after the two support plates 7 are in contact with the inner front and inner rear sides of the two C-shaped steels, the electric heating block 22 moves with the support plate 7 and also contacts with the inner front and inner rear sides of the two C-shaped steels. Then, the conductive plate 21 is energized, and the conductive plate 21 supplies power to the electric heating block 22, so that the electric heating block 22 generates heat to heat the C-shaped steel. The heated area of ​​the electric heating block 22 is the area to be welded. In this way, the two C-shaped steels are preheated before welding, and then the welding operation is carried out, so as to prevent welding cracks. By arranging the electric heating block 22 on the support plate 7, the electric heating block 22 is allowed to move with the support plate 7 close to the two C-shaped steels, so as to perform preheating before welding, and the operation is convenient and quick.

[0031] Example 3 On the basis of Example 2, Figure 8 and Fig.10 As shown, it also includes an air pipe 31 and an air frame 32; two air pipes 31 are fixedly connected to the two support plates 7 respectively; the two air pipes 31 on the same support plate 7 are symmetrically arranged up and down; each air pipe 31 is connected to five air frames 32 respectively; all the air frames 32 are fixedly connected to the support plate 7.

[0032] In order to facilitate the suction of dust in the area of ​​the C-shaped steel facing the electric heating block 22, the opening of the air frame 32 is set to be inclined, facing the area of ​​the C-shaped steel facing the electric heating block 22.

[0033] It also includes a spring telescopic plate 2 33 ; a spring telescopic plate 2 33 is respectively arranged on the left and right sides of each air frame 32 ; the telescopic ends of all the spring telescopic plates 2 33 are slidably connected to the support plate 7 .

[0034] After the C-shaped steel is stored for a long time, a layer of dust will adhere to its inner surface. When the electric heating block 22 is used to preheat the C-shaped steel, the dust will be separated between the electric heating block 22 and the C-shaped steel, and the dust will form a heat insulation layer, which reduces the heat conduction efficiency. The speed at which the heat from the electric heating block 22 is transferred to the C-shaped steel will become slower, and it will take a longer time to reach the required preheating temperature, increasing the preheating time and energy consumption; therefore, the air pipe 31 is connected to the external air pump through a hose in advance, and the sliding plate 4 is manually pushed to slide to the left on the sliding frame 3 through the handle 5. After the sliding plate 4 drives the spring telescopic plate 1 6 and the support plate 7 to enter the cavity formed by the two C-shaped steels, the external air pump is controlled to start, and the dust in the area of ​​the C-shaped steel facing the electric heating block 22 is sucked away through the air pipe 31 and the air frame 32 to prevent the dust from reducing the heat conduction efficiency, and then the two support plates 7 are controlled to move back to back and contact the inner front and inner rear sides of the two C-shaped steels, so that the electric heating block 22 is in contact with the C-shaped steel; In order to facilitate the suction of dust in the area where the C-shaped steel is facing the electric heating block 22, the opening of the air frame 32 is set to be inclined, facing the area where the C-shaped steel is facing the electric heating block 22, and a spring telescopic plate 23 is set on the left and right sides of the electric heating block 22. The spring telescopic plate 23 blocks the left and right sides of the electric heating block 22, so that most of the gas sucked by the air frame 32 flows from the groove 701 to the air frame 32, that is, most of the air flow passes through the area facing the electric heating block 22, thereby enhancing the suction effect of the dust in the area where the C-shaped steel is facing the electric heating block 22; when the two support plates 7 are controlled to move back to back and contact the inner front and inner rear sides of the two C-shaped steels, the spring telescopic plate 23 moves with the support plate 7, and then the telescopic end of the spring telescopic plate 23 contacts the C-shaped steel, and then the C-shaped steel forces the spring telescopic plate 23 to contract. When the support plate 7 contacts the C-shaped steel, the telescopic end of the spring telescopic plate 23 is completely retracted into the support plate 7 without affecting the movement of the support plate 7.

The description of the above embodiments is only used to help understand the method of the present application and its core idea.
