Description

Technical Field

[0001] The present invention relates to the technical field of fan-shaped door welding, in particular to a fan-shaped door and a door panel forming structure. Background Art

[0002] A door is an entrance or exit of a building or a device installed at an entrance that can be opened or closed. It is an entity that divides a limited space and can connect or block the entrances and exits of two or more spaces. Doors come in a variety of shapes, including fan-shaped, rectangular, circular, etc. Fan-shaped doors are one of them.

[0003] When using existing fan-shaped doors, when large objects or vehicles are passing through, the handle needs to be turned to retract the fan blades. When the doors are opened for a long time, there is no fixed protection. If the internal parts are damaged or loose, there is a risk that the fan blades will fall out from the inside, causing damage to personal safety and passing vehicles.

[0004] When processing fan-shaped door panels, it is necessary to perform forming processing operations on the fan-shaped door panel frames. In the existing technology, small fan-shaped door panel frames are mostly stamped by stamping equipment, while large fan-shaped door panel frames cannot be prepared by stamping equipment due to their large size. Therefore, manual work is required to position the frame and weld it. However, due to the large size of the frame, positioning deviation is prone to occur during the frame positioning process. The welding quality is very important for the fan-shaped door, which is directly related to the overall performance and strength of the subsequent fan-shaped door. The existing technologies involved are as follows:

[0005] 1. CN222448975U A welding frame for a civil air defense door frame, comprising a fixed seat, a movable seat, and a slide. The fixed seat is provided with a spacing adjustment member, the movable seat is provided on the spacing adjustment member, the slide slides through the movable seat, the slide is provided with a clamping seat, and the top wall of the movable seat is provided with a positioning seat. This technical solution uses the clamping seat that can be adjusted up and down to position the position of the steel plate according to the required height of the door frame. The two adjustable movable seats can be used to position the steel plates on both sides according to the required width of the door frame, thereby facilitating welding after splicing and improving welding accuracy.

[0006] 2. CN210147349U Door frame steel plate welding fixture, including a placement platform for placing steel plates and a fixture body arranged on the placement platform for clamping the steel plates. The fixture body includes a first clamping plate fixed to the four corners of the placement platform and a second clamping plate that cooperates with the first clamping plate to clamp the steel plates. The placement platform is provided with a support bracket for supporting the steel plates and a lifting assembly that drives the support bracket to rise and fall from the placement platform. The lifting assembly includes a connecting rod arranged at the bottom of the support bracket, a lifting nut arranged on the connecting rod, a screw adapted to the lifting nut, and a motor that drives the screw rod. This technical solution is to provide a support bracket for supporting the steel plates on the placement platform, and to separate the support bracket from the placement platform and the fixture body through the driving assembly, so that the staff can easily remove the steel plates placed on the support bracket.

[0007] In the above technology, the clamping versatility of the device is poor, and it can only realize the clamping and welding operation of the door frame skeleton of a specific shape, and cannot perform the welding and clamping operation on the door frame of different shapes, and cannot adapt to door frames of different shapes;

[0057] It should be noted that in this case, gear one 512 is meshed with gear three 515, and gear four 516 is meshed with gear two 513 and gear five 171 at the same time. The first gear set 172 includes a plurality of gears sequentially arranged on the first transmission shaft 17.

The upper sides of the two plug-in frames 2 are connected by a side connecting piece 4. The multiple first side frames and the multiple second side frames are centered on the central door frame 1. The width of the side connecting piece 4 becomes smaller in sequence, which in turn causes the width of the multiple first side frames and the multiple second side frames to be reduced in sequence, thereby ensuring that during the contraction process, the multiple first side frames and the multiple second side frames can be plugged in and contracted with each other without interfering with each other.

[0066] The flip assembly 69 includes a flip seat 691 disposed in the middle portion of the rotating shaft 67. Slots 692 are provided at the four corners of the flip seat 691. A bidirectional lead screw module 693 is provided on one side below the rectangular through hole 13. A guide rod 694 is provided on the other side below the rectangular through hole 13. Both the bidirectional lead screw module 693 and the guide rod 694 are slidably connected to a seat 695 corresponding to the slot 692.

[0067] It should be noted that when processing the above-mentioned fan-shaped door, it is necessary to perform forming processing operations on the insertion frame 2 and the central side frame 11. For this purpose, it is necessary to first clamp the rod-shaped workpiece, and then adjust the angle and position of the rod-shaped workpiece so that the positions of multiple rod-shaped workpieces correspond to each other, which is convenient for the subsequent welding and forming operations of the overall frame of the above-mentioned fan-shaped door. Since the number of rod-shaped workpieces required for the insertion frame 2 and the central side frame 11 is different, and the required workpiece fixing angles are also different, the welding machine forming processes of the two are different. The specific processes are as follows;

[0068] When processing the center side frame 11, the number of rod-shaped workpieces required is four. The operator can place the rod-shaped workpiece located on the lower side of the center side frame 11 inside the two first limit frames 74, and then control the pair of first hydraulic push rods 76 located on the first assembly frame 71 to operate, and drive the two first moving frames 73 and the two first clamping blocks 77 to move through the first transmission plate 75, and cooperate with the first bearing blocks 78 corresponding to the first clamping blocks 77 to perform a two-point clamping operation on the rod-shaped workpiece. Then, according to usage requirements, the transverse screw module 61 located on the lower side of the transverse slide is controlled to operate, which can drive the workpiece after two-point clamping to move laterally, and then the first rotating seat 63 is controlled to rotate, which can drive the workpiece to adjust its angle so that the angle of the workpiece matches the angle of the lower side of the center side frame 11;

[0069] Subsequently, the operator can place the rod-shaped workpiece located on the upper side of the central side frame 11 inside the second limiting frame 84, and control the operation of a pair of second hydraulic push rods 86 located on the second assembly frame 81, and can drive the second movable frame 83 and the second clamping block 87 to move through the second transmission plate 85, and cooperate with the second bearing block 88 corresponding to the second clamping block 87 to perform a single-point clamping operation on the rod-shaped workpiece. Since the length of the rod-shaped workpiece required on the upper side of the central side frame 11 is smaller than the length of the rod-shaped workpiece required on the lower side of the central side frame 11, a single-point clamping method is adopted here. At the same time, in order to ensure the effect of single-point clamping, the width of the second clamping block 87 and the second bearing block 88 must be greater than the width of the first clamping block 77 and the first bearing block 78 to ensure the clamping quality. Subsequently, according to the use requirements, the longitudinal screw module 64 located on the lower side of the longitudinal slide is controlled to operate, so that the workpiece after single-point clamping can be driven to move longitudinally through the second movable seat 65. Subsequently, the second rotating seat 66 is controlled to rotate, and the workpiece can be driven to adjust the angle so that the angle of the workpiece matches the angle of the upper side of the central side frame 11.

[0070] At the same time, the movable screw module 91 is controlled to operate, and in conjunction with the slide 92, the electric push rod 93, the lifting seat 94, the adjusting screw module 95, the adjusting seat 96 and the welding gun 97, the rod-shaped workpiece after the clamping and fixing can be automatically welded. The adjusting seat 96 is provided with installation stations on both sides, and equipment such as a fume treatment device can be welded on the adjusting seat 96, which is convenient for improving the subsequent welding effect and ensuring the welding quality of the fan-shaped door panel.

[0071] After the forming and welding of the center side frame 11 is completed, the subsequent plug-in frame 2 needs to be formed and welded. Compared with the center side frame 11, the plug-in frame 2 has different overall angles and widths, and the number of rod-shaped workpieces required is different. The plug-in frame 2 only needs three rod-shaped workpieces. At this time, the servo motor 68 can be controlled to operate, and the turning seat 691 can be rotated 180 degrees through the rotating shaft 67. Then, the bidirectional screw module 693 is controlled to operate to drive the card seat 695 to be plugged into the card slots 692 at the four corners of the turning seat 691, so that the position of the turning seat 691 can be fixed, and the guide rod 694 can increase the stability of the card seat 695 during movement.

[0072] At this time, the second clamping portion 8 located on the upper side of the flip seat 691 is hidden. Since the second clamping portion 8 is in an idle state when the inserting frame 2 is being formed and welded, hiding it can prevent the second clamping portion 8 on the flip seat 691 from interfering with the placement and adjustment of the rod-shaped workpiece during the subsequent forming and welding of the inserting frame 2, thereby increasing the operating space during the welding and forming of the inserting frame 2 and ensuring the subsequent welding and forming effect. Subsequently, the two first clamping portions 7 and the remaining second clamping portion 8 repeat the above-mentioned rod-shaped workpiece clamping and fixing operation, and then the welding and forming operation of the inserting frame 2 can be achieved with the help of the welding gun.

[0073] Among them, the first rotating seat 63 and the second rotating seat 66 are both composed of a rotating disk and a driving device, and a motor is arranged inside the driving device. This part is the existing technology, so it is not described in detail. At the same time, a limiting component is arranged on the upper side of the frame 6. The limiting component is mainly composed of a linear drive and a rough part placed on the frame 6. After the angle adjustment of the first clamping part 7 and the second clamping part 8 is completed, the linear drive can push the rough part to fit tightly against the outer side of the rotating disk on the first rotating seat 63 and the second rotating seat 66. Through the friction force between the rough part and the rotating disk, the purpose of limiting the angle of the first clamping part 7 and the second clamping part 8 after adjustment is achieved, preventing the subsequent workpiece angle from being offset. The thickness of the rough part is relatively small and will not interfere with the movement of the first clamping part 7 and the second clamping part 8.

[0074] There are multiple positioning screw holes evenly arranged on the flip seat 691, and the lower side of the second assembly seat located on the upper side of the flip seat 691 is connected to the positioning screw holes through bolts. Therefore, the second clamping part 8 located on the flip seat 691 can also be adjusted in angle and position within a certain range to meet the different usage requirements of users.

[0075] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
