The processing technology of the type is characterized in that: the flanging machine is not moved, and the steel door plate is moved. The disadvantages are that:

firstly, intensity of labour is big, and whole process flow needs the incessant manual transport steel door plant of two operating personnel, and operating personnel will process two hundred more steel door plants every day, and each transport 4 times from top to bottom for every door plant of processing, and each nearly thousand times of transport about every day for every operating personnel, and every standard steel door plant is heavy about 37 Kg.

Secondly, the processing quality is not high, the edge is positioned by the support on the flanging machine, the manual operation is often performed in the flanging process, and the positioning is often not accurate due to the longer long edge.

This left steel door plant module and right steel door plant module all can control the distance about moving of locating pin 432 to aim at locating hole 2 on the left steel door plant or the locating hole 2 on the right steel door plant.

The processing flow of the hemming device of the preferred embodiment is as follows:

1. the stacked steel door plates 1 (with the thickness of 0.5mm-2.5mm) to be processed are placed on the incoming material storage table, and 2 magnet separation devices (not shown) are respectively placed at two ends, close to the stacked steel door plates 1, of the incoming material storage table, so that each steel door plate 1 is automatically separated, and the problem that the plates are adhered to each other when the steel door plates 1 are conveyed is solved.

2. The first conveyor 24 located above the steel door panel 1 is automatically started, descends under the action of the linear guide rail 22, the grabbing and releasing adsorption piece 21 adsorbs one steel door panel 1 and then ascends and returns, and then the first conveyor 24 is longitudinally conveyed to the position above the plate positioning table 30 and descends through the linear guide rail 22 to place the steel door panel 1 on the plate positioning table 30 through the rail of the supporting piece 11.

3. The first positioning air cylinder 32 and the second air cylinder of the air cylinder primary positioning table automatically push the steel door plate 1 to be aligned to be close to the edge from the directions of x1-x2 and y1-y 2. The aligned steel door panel 1 is sucked and lifted back again by the grabbing and releasing suction part 21 of the first conveyor 24, longitudinally conveyed to the position above the bearing platform 43 of the numerical control walking device 40 through the support 11, lowered and placed on the bearing platform 43 through the linear guide rail 22, then the positioning pin 432 on the bearing platform 43 is aligned and moved upwards to be inserted into the positioning hole 2 of the steel door panel 1, and automatically and accurately positioned, and the positioning suction part 434 on the bearing platform 43 is used for sucking the steel door panel 1.

4. Then, the bearing platform 43 moves the steel door panel 1 longitudinally to the first automatic edge folding machine 51 through the first traveling rail 41, and positions and places the steel door panel 1 to be folded. The presser foot 55 of the first automatic hemming machine 51 moves down to press the steel door panel 1 by the hydraulic cylinder 58 (see fig. 3) and drives the turning folding knife 57 to turn from the vertical position to the working position by 90 degrees for hemming operation. After the long edge folding of one side of the steel door panel 1 is completed, the presser foot 55 and the turning folding knife 57 are reset.

5. Then, the bearing platform 43 longitudinally moves the steel door panel 1 to the second automatic edge folding machine 52 through the first traveling rail 41 again, and the long edge folding of the other side of the steel door panel 1 is completed. The bearing platform 43 is reset to the central initial position, and the steel door plate 1 is transversely moved to the third automatic edge folding machine 53 through the second walking track 42, so that the short edge folding of one side of the steel door plate 1 is completed. Then, the carrying platform 43 moves the steel door panel 1 to the third automatic edge folding machine 53 again through the second traveling rail 42, and the short edge folding of the other side of the steel door panel 1 is completed. The above-described hemming operation is substantially the same as that of the first automatic hemming machine 51, and will not be described in detail herein. The structure of the steel door plate 1 with four edges folded is shown in figure 7.

6. After the four edges of the steel door plate 1 are folded, the bearing platform 43 is reset to the central initial position, and the positioning pin 432 of the bearing platform 43 is reset. The second conveyor 25 automatically moves from the right side of the supporting part 11 to the upper side of the bearing platform 43, and after horizontally rotating the grabbing and releasing adsorption part 21 to a set angle through the rotating head 23, the second conveyor descends and adsorbs the flanged steel door plate 1 and then ascends and returns. The hemmed steel door panel 1 is then conveyed longitudinally at a set angle to a hemming steel door panel 1 conveyor line (not shown).

7. And according to the preset program, when the next steel door plate 1 after flanging is conveyed, the rotating head 23 of the second conveyor 25 is kept still. And the last rotation angle and the next rotation angle are kept unchanged, and the process is analogized so as to achieve the aim of realizing the staggered stacking of the steel door plates 1 and ensure the stability of the stacking of the steel door plates 1.

All the actions are fully automated by the numerical control operating system 60. If the left steel door plate and the right steel door plate need to be distinguished, an operator only needs to select a preset left steel door plate module and a preset right steel door plate module before the edge of the steel door plate 1 is folded, and then the operation can be started.

The invention has the advantages that: the novel automatic flanging machine for the steel door plate adopts a numerical control walking device, and can finish all processing steps by single operation. The production efficiency and the processing quality are greatly improved. Four flanging machines surround the overall arrangement, have shortened the processing stroke, process time has improved production efficiency. The angle of the steel door plate is fixed and unchanged, and the flanging quality of the steel door plate is improved by adopting the flanging and flanging processing technology of the flanging machine. The punched holes on the steel door plate are used as positioning holes, and the bearing platform with the accurate hole pins is used for flanging and positioning, so that the flanging precision of the steel door plate is improved, and the flanging quality is improved.
