[0024] As Figure 1 shown, a steel plate step feeding device includes a support frame 2 arranged on the side of the punching press 1 for supporting the steel plate, a moving frame 3 arranged in the support frame 2 and moving in the support frame 2, and a driving mechanism arranged in the support frame 2 for driving the moving frame 3 to move. Two frames are symmetrically arranged before and after the support frame 2. The output end of the support frame 2 cooperates with the die of the punching press 1. In this embodiment, the output end of the support frame 2 refers to the left end of the support frame 2. The moving frame 3 includes a crossbeam I 31 at the bottom and a plurality of levers 32 arranged on the upper end of the crossbeam I 31;

[0025] During operation, the steel plate is placed on the support frame 2, and the driving mechanism continuously drives the moving frame 3 to move. The moving track of the moving frame is elliptical, and the levers 32 on the crossbeam I 31 continuously push the steel plate to the left, realizing the feeding operation of the punching press and reducing the labor intensity.

[0026] A plurality of levers 32 can simultaneously position a plurality of steel plates, and the positioning effect is good.

[0027] As Figure 2 and Figure 3As described above, the driving mechanism includes swing rods 4 symmetrically arranged on the left and right and rotatably connected to the support frame 2 at the upper ends, a rotating frame 18 provided at the bottom of the swing rod 4 and rotatably connected to the swing rod 4, and fixing rods 5 provided at both ends of the moving frame 3.

A driving shaft 7 is provided at the bottom of the support frame 2, and a rotating rod 8 is provided on the driving shaft 7. The end of the rotating rod 8 is rotatably connected to the left end of the right rotating frame 18. The rotation of the driving shaft 7 and the rotation of the main shaft of the punching machine 1 are linked by a linkage mechanism. The left rotating frame 18 is in an inverted V shape and consists of two rotating rods. The bottom of the left fixing rod 5 is rotatably connected to the connection positions of the two rotating rods. The right rotating frame 18 consists of three connecting rods. The bottom of the right fixing rod 5 is rotatably connected to the connection positions of the three rotating rods.

[0028] The swing rods 4 and the rotating frames 18 symmetrically arranged on the left and right can ensure that both sides of the moving frame 3 are synchronously stressed during lifting, closing, and moving, with good stability.

[0029] The driving shaft 7 rotates and drives the rotating rod 8 to rotate. The rotating rod 8 rotates clockwise. When the rotating rod 8 swings from left to right, at this time, the right rotating frame 18 rotates clockwise, and under the action of the connecting rod 6, the left rotating frame 18 rotates clockwise. At this time, the moving frame 3 moves downward and backward to the right. The rotating rod 8 continues to rotate clockwise and swings from right to left.

At this time, the moving frame 3 moves upward and forward to the left. The steel plate is pushed to the left and enters the punching machine 1 for stamping operations, realizing automatic feeding of the steel plate and reducing labor intensity. At the same time, as the rotating rod 8 rotates, the moving frame 3 continuously pushes the steel plate to the left into the punching machine 1 in sequence, with a compact rhythm and high efficiency.

A first bevel gear 12 is provided on the first rotating shaft 11, and a second bevel gear 13 meshing with the first bevel gear 12 is provided at the rear end of the drive shaft 7.

Pulley wheels cooperating with the first belt 15 are provided on both the second rotating shaft 14 and the driving shaft of the punching machine 1. The first rotating shaft 11 is connected to the second rotating shaft 14 through a second belt 16. Pulley wheels cooperating with the second belt 16 are provided on both the first rotating shaft 11 and the second rotating shaft 14. The rotation of the second rotating shaft 14 is linked to the driving shaft of the punching machine 1, without the need for separate drive, and the cost is low.
