[0120] The working principle of the present invention is:

The limiting cylinder 84 limits the position of the stacked slide rail raw material plates 12. When the present invention positions the discharge, the first lifting cylinder 82 lifts the stacked slide rail raw material plates 12 on the left and right support plates to keep the stacked slide rail raw material plates 12 horizontal, which is convenient for the suction cup 251 on the suction arm 25 to absorb the slide rail raw material plates 12. When the present invention is working, the horizontal transfer cylinder 21 drives the horizontal transfer seat 22, the lifting cylinder 23, the lifting seat 24, and the suction arm 25 to move above the stacked slide rail raw material plate 12, and then the lifting cylinder 23 drives the lifting seat 24 and the suction arm 25 to descend, and the suction cup 251 on the suction arm 25 sucks up the single slide rail raw material plate 12, and the horizontal transfer cylinder 21 drives the suction arm 25 to move, and the suction arm 25 places the single slide rail raw material plate 12 on the horizontal feeding belt 61. After the suction arm 25 unloads, the left and right sorting mechanisms 2 and 3 return to their original positions and suck the next slide rail raw material plate 12. The suction arm 25 repeats this action continuously, and the stacked slide rail raw material plates 12 can be separated one by one onto the horizontal feeding belt 61.

[0122] The motor 41 is driven by the driving gear 40, the third driven gear 49, the chain (not shown in the figure), the first driven gear 42, and the second driven gear 43, and then drives the two driving rollers 63 to rotate in the opposite direction, and finally drives the two horizontal feeding belts 61 to rotate from the two sides of the frame 1 to the middle of the frame 1.

Then the bending stamping die 35 starts to stamp the slide rail raw material plate 12. The bending stamping die 35 bends the plate body of the slide rail raw material plate 12 into an L shape, and the inverted hook 126 is located at one end of the plate body.

[0127] Next, the fifth swing-arm feeding robot 315 grabs the two slide rail raw material plates 12 that have completed the bending process on the bending stamping die 35, and respectively places them into the two raw material plate positioning grooves 319 on the workbench 320 of the rib punching stamping die 36. Then the rib punching stamping die 36 starts to punch the slide rail raw material plates 12, and the rib punching stamping die 36 punches out reinforcing ribs 127 on the plate body of the slide rail raw material plates 12.

[0128] Next, the sixth swing arm feeding robot 316 grabs the two slide rail raw material plates 12 that have completed the rib punching process on the rib punching die 36, and puts them into the two raw material plate positioning grooves 319 on the workbench 320 of the punching hook punching die 37 respectively. Then the punching hook punching die 37 starts to punch the slide rail raw material plate 12, and the punching hook punching die 37 punches out the hook 128 on the plate body of the slide rail raw material plate 12. At this point, the production line of the present invention has completed all stamping processes of the slide rail raw material plate 12, and the two slide rail raw material plates 12 have been punched into slide rails.

[0129] Then, the seventh swing-arm feeding robot 317 grabs the two slide rails on the punch hook punching die 37 and places them on the material receiving positioning table 38 .

[0130] Then, the unloading robot 39 grabs the two slide rails on the receiving and positioning platform 38 and positions them on the middle positioning seat 383 of the receiving and positioning platform 38 , and then grabs two more slide rails and puts them into the slide rail receiving frame 310 .
