Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] like Figure 1-4 As shown: This embodiment provides a fire door frame welding forming device, including a welding seat 100, a support 101 is fixedly connected to the middle of the welding seat 100, a bracket 102 is fixedly connected to the top center of the support 101, both ends of the middle of the welding seat 100 are rotatably connected to bidirectional screws 103, two symmetrically arranged clamping plates 104 are threadedly connected between the two bidirectional screws 103, two symmetrically arranged clamping motors 116 are fixedly connected to the top of one side of the welding seat 100, the output shafts of the clamping motors 116 are fixedly connected to one end of the adjacent bidirectional screws 103, and one end of the welding seat 100 is fixedly connected to the top. Two symmetrically arranged telescopic rods 105, the top of the telescopic end of the telescopic rod 105 is fixedly connected to the same support plate 106, the bottom of the support plate 106 is fixedly connected to a baffle 107, the middle of both ends of the welding seat 100 are rotatably connected to a transmission shaft 112, two symmetrically arranged conveyor belts 113 are sleeved between the two conveyor shafts 112, the width of the baffle 107 is smaller than the spacing between the two conveyor belts 113, the top of the bracket 102 is in contact with the top inner wall of the conveyor belt 113, one side of the welding seat 100 is fixedly connected to a drive motor 115, and the output shaft of the drive motor 115 is fixedly connected to one end of the adjacent conveyor shaft 112;

[0023] During welding, the door frame is placed on the top of the conveyor belt 113, and then the movement of the clamping motor 116 is controlled to rotate the bidirectional screw 103, thereby driving the clamping plate 104 to clamp the door frame. After the clamping is completed, the door frame is located at the center position between the two conveyor belts 113, and then the clamping motor 116 is driven to reverse and release the door frame. At the same time, the driving motor 115 is started to drive the conveying shaft 112 and the conveyor belt 113 to rotate, and the door frame moves. At this time, the two telescopic rods 105 are driven to move synchronously, so that the baffle 107 falls, and the bottom of the baffle 107 passes through The two conveyor belts 113 are fitted with the top of the bracket 102 to limit the door frame. Finally, the door frame is fitted with the baffle 107 under the drive of the conveyor belt 113 to limit the baffle 107. At this time, the clamping motor 116 is started again to limit the two sides of the door frame. The conveyor belt 113 continues to move so that the door frame is always fitted with the baffle 107 to achieve the positioning of the door frame. The bidirectional screw 103 and the baffle 107 make the device adapt to door frames of different widths and can position and clamp door frames of different sizes, thereby improving the versatility of the device.

[0024] Welding frame 108 Figure 2 , 4 As shown,

[0025] The top of the welding seat 100 is fixedly connected to a welding frame 108, and the four corners of the welding frame 108 are fixedly connected to telescopic columns 109. The bottom of the telescopic end of the telescopic column 109 is fixedly connected to the same mounting plate 110, and the bottom sides of the mounting plate 110 are fixedly connected to multiple array-arranged welding guns 111;

[0026] When the door frame reaches the welding position and is fixed, the welding gun 111 is adjusted to a suitable height by controlling the telescopic column 109 to operate synchronously, and then the welding gun 111 at the appropriate position is started for welding. The number of welding guns 111 started is adjusted according to actual production needs to meet the welding needs of different door frames.

[0027] The guide rod 114 is as follows Figure 1 As shown,

[0028] One end of the welding seat 100 is fixedly connected to two guide rods 114 through a connecting plate. The bottom of the guide rod 114 is in contact with the top of the conveyor belt 113. The guide rod 114 is arc-shaped, and the outer arc surface faces the middle of the welding seat 100.

[0029] In the automated assembly line working mode, after the door frame is bent, it is automatically sent to the welding forming device. The guide rod 114 can correct the direction and posture of the door frame when it enters the welding area to ensure the accuracy and quality of welding.

[0030] Working principle:

[0031] First, the door frame is placed on the conveyor belt 113. Through the cooperation of the bidirectional screw 103 and the clamping motor 116, the clamping plate 104 clamps the door frame to ensure the accuracy of the position of the door frame during the transmission process. Then, the drive motor 115 is started, driving the transmission shaft 112 and the conveyor belt 113 to rotate, and the door frame moves accordingly. During this process, the telescopic rod 105 moves synchronously to make the baffle 107 fall and fit with the top of the bracket 102 to limit the position of the door frame. When the door frame reaches the welding position, it is limited by the door frame. The telescopic column 109 adjusts the welding gun 111 to a suitable height, and starts the corresponding number and corresponding position of the welding gun 111 for welding. In addition, the design of the guide rod 114 enables the door frame to correct its direction and posture when it automatically enters the welding area.

[0032] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0033] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
