[0019] The present invention is illustrated below with specific embodiments, but these are not intended to limit the invention.

[0020] Example 1 like Figures 1-9 As shown, in this embodiment, a fire door assembly welding device is provided, including a frame 1; a welding groove 2 is provided on the frame 1, the welding groove 2 is rectangular, used to accommodate the assembled fire door frame, and welding components are provided at each of the four corners of the welding groove 2; two first storage racks 3 are symmetrically arranged on both sides of the upper surface of the frame 1, and the two first storage racks 3 are located inside the welding groove 2; two second storage racks 4 are symmetrically arranged at both ends of the upper surface of the frame 1, and the two second storage racks 4 are located outside the welding groove 2; wherein, a pusher plate 5 slides on the frame 1 and below the two first storage racks 3, and the pusher plate 5 has a first fork groove 501 with an opening facing the welding groove 2, such as Figure 6 As shown, when the pusher plate 5 moves into the welding groove 2, the upper surface of the pusher plate 5 is located at the lower end of the first fork groove 501, supporting the door frame vertical bar of the first storage rack 3. The upper side of the first fork groove 501 is shorter than the lower side. Thus, when the pusher plate 5 retracts towards the middle of the frame 1, after the upper side of the first fork groove 501 moves away from the lower end of the first storage rack 3, the lowest door frame vertical bar of the first storage rack 3 falls into the first fork groove 501 and is supported by the lower side of the first fork groove 501. At this time, the first fork groove 501 forks the door frame vertical bar and moves towards the welding groove 2, realizing the splicing of the door frame in the welding groove 2. At the same time, the upper surface of the pusher plate 5 supports the door frame vertical bar of the first storage rack 3, preventing the other door frame vertical bars from falling. The rack 1 is slidably provided with a pulling plate 6 below the two second material storage racks 4, and the pulling plate 6 is provided with a second fork material groove 601 with an opening facing the welding groove 2. The operation principle of the pulling plate 6 is the same as that of the pushing plate 5, and thus is not described herein.

[0021] The four material rods pushed from the first material storage racks 3 and the second material storage racks 4 into the welding groove 2 by the pushing plate 5 and the pulling plate 6 are spliced into a fireproof door frame, and the welding assembly is used to weld the connection, so as to realize automatic splicing and welding integrated operation.

[0022] The second material storage rack 4 is fixed with a baffle 401 at the lower end of the two sides for preventing the door frame cross bar from moving. When the pulling plate 6 pulls the door frame cross bar towards the welding groove 2, the two ends of the door frame cross bar are limited by the baffle 401, and the door frame cross bar moves horizontally towards the welding groove 2, effectively avoiding the movement of the door frame cross bar in length, and when the door frame cross bar moves towards the welding groove 2, the vertical bar that may have moved in the length direction can be corrected, thereby improving the welding precision.

[0023] The rack 1 is provided with a gantry 15, the gantry 15 is fixed with a hanging rod 1501, the hanging rod 1501 is fixed with a second motor 16, the second motor 16 is drivingly connected with the double-head screw 7 through a belt, and the double-head screw 7 can be driven to rotate by the second motor 16.

[0024] Embodiment two On the basis of embodiment one, in the embodiment, The rack 1 is rotatably provided with a double-head screw 7, and the double-head screw 7 is symmetrically and threadedly connected with two sliding blocks 8; The two sliding blocks 8 are rotatably connected with a top rod 9 at the two sides, and the top rod 9 is hingedly connected to the pushing plate 5 on the same side away from the sliding block 8; The two sliding blocks 8 are connected with the pulling plate 6 through a connecting rod 10; When the double-head screw 7 is rotated to drive the two sliding blocks 8 to move towards the middle part of the double-head screw 7, the sliding block 8 drives the pushing plate 5 to move through the top rod 9, and the sliding block 8 drives the pulling plate 6 to move through the connecting rod 10, so as to realize that the pushing plate 5 pushes the door frame vertical bar in the first material storage rack 3 into the welding groove 2, and the pulling plate 6 pulls the door frame cross bar in the second material storage rack 4 into the welding groove 2.

[0025] The lower end of the welding groove 2 is open, which is convenient for the welded fireproof door frame to fall out of the welding groove 2, so as to leave the welding groove 2 and realize continuous welding.

[0026] The second storage rack 4 is fixed with a connecting plate 17 on the side facing the welding groove 2, and the end of the first storage rack 3 is fixed on the side wall of the connecting plate 17, so that the second storage rack 4 and the first storage rack 3 are connected into a whole through the connecting plate 17. Since the lower end of the welding groove 2 is open, the table top of the rack 1 on the inside and outside of the welding groove 2 is separated, and the first storage rack 3 and the second storage rack 4 are connected through the connecting plate 17, so that the table top on the inside of the welding groove 2 is effectively supported.

[0027] One end of the connecting rod 10 is rotatably connected to the sliding block 8 through a rotating shaft, and the end of the connecting rod 10 is connected with the sliding block 8 through the first spring 11. The side wall of the material pulling plate 6 is provided with an arc-shaped groove 602 with an open lower end and an arc center coinciding with the rotating point of the connecting rod 10. The connecting rod 10 is fixed with an insertion block 1001 which is slidably connected in the arc-shaped groove 602. Under the action of the first spring 11 without external force, the connecting rod 10 can be in a horizontal state. When the connecting rod 10 rotates to the horizontal state, the insertion block 1001 is located at the upper end of the arc-shaped groove 602. When the sliding block 8 moves, the insertion block 1001 is located in the arc-shaped groove 602, and the connecting rod 10 can drive the material pulling plate 6 to slide. The sliding of the material pulling plate 6 can push the door frame cross bar in the second storage rack 4 into the welding groove 2. After the door frame is welded, the material pushing plate 5 and the material pulling plate 6 are reset and moved out of the welding groove 2. At this time, only the connecting rod 10 interferes with the door frame moving out of the welding groove 2. The door frame will press down the connecting rod 10 during the falling process under the action of gravity, so that the connecting rod 10 overcomes the pulling force of the first spring 11 and rotates downward. When the connecting rod 10 rotates downward, the insertion block 1001 can slide out of the arc-shaped groove 602 from the lower end opening of the arc-shaped groove 602, so that the connecting rod 10 is separated from the material pulling plate 6. At this time, after the connecting rod 10 rotates to the vertical state, the interference is eliminated, and the door frame can move out of the welding groove 2. After the door frame moves out, the connecting rod 10 is reset to the horizontal state under the action of the pulling force of the first spring 11, and the insertion block 1001 is slid into the upper end position of the arc-shaped groove 602.

[0028] The upper end of the arc-shaped groove 602 is higher than the rotating shaft of the connecting rod 10 and the sliding block 8. When the sliding block 8 pulls the material pulling plate 6 to slide through the connecting rod 10, the insertion block 1001 is located at the upper end of the arc-shaped groove 602. The height of the insertion block 1001 is higher than the height of the rotating shaft of the connecting rod 10 and the sliding block 8, which can increase the stability of the insertion block 1001 in the arc-shaped groove 602 and prevent the insertion block 1001 from falling out of the arc-shaped groove 602.

[0029] The side wall of the material pulling plate 6 is fixed with a guide rod 603 which is slidably sleeved on the side wall of the rack 1, and the guide rod 603 is sleeved with a second spring 12. One end of the second spring 12 abuts against the end of the guide rod 603, and the other end of the second spring 12 abuts against the side wall of the rack 1. When the pulling plate 6 moves towards the welding groove 2, the second spring 12 is gradually compressed; When the plug-in block 1001 is separated from the arc-shaped groove 602, the elastic pressure of the second spring 12 can keep the pulling plate 6 in a fixed position, so that when the connecting rod 10 rotates upwards with the plug-in block 1001, it ensures that the plug-in block 1001 can be turned into the arc-shaped groove 602 from the lower end opening of the arc-shaped groove 602.

[0030] Embodiment three On the basis of the above-mentioned embodiments, in this embodiment, the rack 1 and below the welding groove 2 are provided with a conveying belt 13 for conveying the door frame, the conveying belt 13 is driven to rotate by the first motor 14, as shown in Figure 1 As shown in Figure 3 The rack 1 is provided with a plurality of rollers, the conveying belt 13 is supported by the plurality of rollers, the first motor 14 is fixed on the side wall of the rack 1, and the output shaft of the first motor 14 is in transmission connection with any roller, when the first motor 14 is started, the output shaft of the first motor 14 rotates with the roller shaft, so that the conveying belt 13 rotates, thereby the door frame falling on the conveying belt 13 can be conveyed out of the rack 1, which is convenient for subsequent processing.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present application, although the present application has been described in detail with reference to the above-mentioned embodiments, those skilled in the art should understand that the present application can still be modified or replaced by the equivalent, without departing from the spirit and scope of the present application, any modification or partial replacement should be covered in the scope of the claims of the present application.
