DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0034] As Figures 1-8This invention provides a technical solution: an automatic welding and forming device for fire door frames, comprising: a conveyor belt 1, arranged parallel to each other at intervals, for outputting welded fire door frames, i.e., for outputting welded fire door frames; a gantry frame 2, spanning the conveyor belts 1, with an automatic welding mechanism 3 suspended on its top; and a feeding mechanism 5, arranged at right angles and formed into a square feeding system by diagonally arranged and fixed columns 4, for inputting fire door frame panels, i.e., for inputting, fixing, and shaping unwelded fire door frame panels so that the automatic welding structure can perform the welding process.

[0035] Combination Figure 1 , Figure 2 As shown, the feeding mechanism 5 includes a corner frame 51, with a fixed corner seat 52 installed at its central corner, and positioning channel frames 53 installed at its two outer right-angle ends, and the two positioning channel frames 53 are respectively connected to the first conveyor roller group 54 and the second conveyor roller group 55; wherein, taking the embodiment of the present invention as an example, the height of the feeding mechanism located on the lower left corner is lower than that of the feeding mechanism located on the upper right corner, so as to facilitate the automated conveying of a set of frame plates (four frame plates placed according to their respective position directions) of a fire door frame.

[0036] Combination Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the positioning channel frame 53 includes a positioning component 531, which is arranged at right angles and assembled on the corner frame 51. The positioning component 531 includes a second telescopic device 532, the output end of which is fixed with an H-shaped plate 533. A bidirectional telescopic device 534 is installed on the long plate of the H-shaped plate 533. F-shaped plates 535 are fixed to the upper and lower output ends of the bidirectional telescopic device 534, respectively. A guide roller 536 is installed on the F-shaped plate 535. Before the frame plate enters the positioning channel frame, the second telescopic device, arranged at right angles, is in a retracted state, and the right angle coverage area formed by the vertical and horizontal F-shaped plates is greater than the cross-sectional area of ​​the frame plate. In specific implementation, for example, after placing the frame plate on the corresponding conveyor roller group one and conveyor roller group two, automated conveying can be performed. When one end of the frame plate enters the channel range of the positioning channel frame, combined with... Figure 4 As shown, the second horizontal and vertical telescopic device in the positioning assembly on the left first extends until the guide roller touches the frame plate. At this time, the second horizontal and vertical telescopic device in the positioning assembly on the right then extends until the guide roller touches the frame plate. Finally, when all the guide rollers are completely in contact with the surface of the frame plate, the guiding and positioning of the frame plate is completed, and it is continuously sent to the fixed corner seat.

[0037] Combination Figure 1 , Figure 2 , Figure 3As shown, the fixed angle seat 52 includes a right-angle outer plate 521, with fixed conveying components 522 respectively installed on its upper and lower surfaces. The fixed conveying components 522 include: a moving guide rail 523 fixed on the right-angle outer plate 521; and a telescopic device 524 installed on the moving guide rail 523 and vertically arranged, with a right-angle inner clamping plate 525 fixed at its output end. In specific implementation, for example, after the positioning channel frame is positioned and guided, the chamfered end of the frame plate will gradually move towards the right-angle surface of the right-angle outer plate. After the chamfered ends of the two right-angle conveyed frame plates abut and connect with each other, a right-angle connecting frame plate is formed. Then, the telescopic device drives the right-angle inner clamping plate to press against the inner right-angle surface formed by the two right-angle connecting frame plates and clamp and fix it. After that, the positioning channel frame returns to its initial state structure, detaches from the frame plate, and can be controlled by the moving guide rail to transfer the two right-angle connecting frame plates to the automatic welding mechanism.

[0038] Combination Figure 1 , Figure 6 , Figure 7 , Figure 8 As shown, the automatic welding mechanism 3 includes: a hanging column 31, fixedly connected to the top of the gantry frame 2, with a hanging box 32 fixedly connected to its lower end; vertical moving guide rails 33 are respectively installed on the middle parts of the four side walls of the hanging box 32, and clamping seats 6 for clamping the fire door frame plates are installed on the moving guide rails 33; support arm plates 34 are fixedly distributed at the four corners of the top of the hanging box 32, and automatic welding frames 7 are installed on the outer ends of the support arm plates 34; wherein, in specific implementation, for the process of transferring two right-angle butt-joint frame plates to the clamping seats by the moving guide rail, for example: initially, the moving guide rail adjusts the clamping seats to be located on the lower side of the hanging box, and the moving guide rail 34 is on the lower side of the hanging box. Moving upwards under control, firstly, when passing the feeding mechanism located on the lower left side, the clamping seats on the left and front sides clamp the middle of the two frame plates of the right-angled joint frame plate formed on the lower left side. After completion, it moves upwards again, and when passing the feeding structure located on the upper right side, the clamping seats on the right and rear sides clamp the middle of the right-angled joint frame plate formed on the upper right side. After the fire door frame plate is welded, it is transferred downwards to the conveyor belt through the cooperation of the moving guide rail and the clamping seats, so that the welded fire door frame can be sent out. When it moves upwards again, the next set of fire door frames can be welded, thereby greatly improving the welding efficiency of fire door frames.

[0039] Combination Figure 6 , Figure 7 , Figure 8 As shown, the clamping base 6 includes a telescopic device 3 61, one end of which is connected and fixed to the moving guide rail 2 33, and the other end of which is fixed to a concave base 62. The upper and lower ends of the concave base 62 are respectively equipped with telescopic devices 4 63, and the output end of the telescopic device 4 63 is fixed with a concave clamping plate 64.

Initially, the telescopic device 75 adjusts the opening state of the semi-circular ring shell. It should be noted that when the semi-circular ring shell is open, the semi-circular ring shell is exactly aligned with the semi-circular ring block 76.

[0044] Step 3: Position the monitoring frame plate of the channel frame and guide and position the frame plate;

[0045] Step 4: When the chamfered ends of the two frame plates in the feeding mechanism meet and abut to form a right-angled frame plate, the telescopic device adjusts the right-angled inner clamping plate to clamp and fix the right-angled frame plate. After that, the positioning channel frame is reset. After that, the moving guide rail adjusts the right-angled frame plate to move towards the self-feeding welding mechanism.

[0046] Step 5: The moving guide rail adjusts the clamping seat to move upward. When it passes the feeding mechanism located on the lower left side, the clamping seats on the left and front sides clamp the middle of the two frame plates of the right-angle docking frame plate formed on the lower left side. After completion, it moves upward again. When it passes the feeding structure located on the upper right side, the clamping seats on the right and rear sides clamp the middle of the right-angle docking frame plate formed on the upper right side, and then move upward again.

[0047] Step Six: After the fire door frame that has completed the contact and docking enters the automatic welding frame, the expansion joint five controls the semi-circular shell to close, and the motor is started to control the rotation of the semi-circular shell to drive the welding head to weld the fire door frame.

[0048] Step 7: After welding is completed, the expansion joint five adjusts the semi-circular shell to open, and the moving guide rail two adjusts the welded fireproof door frame to move towards the conveyor belt, so that the welded fireproof door frame can be conveyed out, and the next welding of the fireproof door frame can be carried out.
