[0002] Motor punching sheets are a common component in motors. They are generally made of silicon steel. Multiple motor punching sheets are stacked to form motor rotor magnets or motor stator magnets. Punching operations are required during the production and processing of punching sheets. The punching machine works by continuously closing and opening the upper and lower dies with blades to punch out the punching sheet blanks. Currently, the punching sheet blanks to be punched are generally placed manually in a fixed position on the lower die, which is not only inefficient but also prone to work-related injuries due to operational errors. Summary of the invention

The punching machine is provided with a matching upper die and a lower die, the lower die is fixedly arranged, the upper die is installed on the punching mechanism of the punching machine, and the punching mechanism moves up and down and closes and opens with the lower die to realize punching, including a pushing mechanism and a limiting device. A workbench is provided on one side of the punching machine, and a feeding body including a transfer slide rail and a sheet blank stacking mechanism is provided on the workbench. The sheet blank stacking mechanism is located above the transfer slide rail and is used for stacking the sheet blanks and making the sheet blanks fall onto the transfer slide rail one by one. The pushing mechanism includes a slider and a transmission mechanism. The transmission mechanism is connected with the punching mechanism, and the slider is driven by the swing of the punching mechanism to slide back and forth in the feeding body to push the sheet blanks falling on the transfer slide rail to the lower die of the punching machine. The limiting device is arranged on the punching machine to limit and resist the sheet blanks pushed from the transfer slide rail, so that the sheet blanks fall at the fixed position of the lower die.
[0005] Furthermore, one side of the slider is provided with a stopper that passes through the feeding body, and the transmission mechanism includes a swinging assembly connected to the punch press, and the stamping mechanism is provided with a push-pull member that cooperates with the swinging assembly. The push-pull member moves up and down with the stamping mechanism to push and pull the swinging assembly, so that the swinging assembly swings back and forth along the transition, and a pair of push rods that cooperate with the stopper are provided at the bottom of the swinging assembly, and the stopper is located between the pair of push rods. When the swinging assembly swings, the pair of push rods push the stopper back and forth to realize the reciprocating sliding of the slider.
[0006] Further, the swing assembly includes an upper piece and a lower piece, and the lower piece can rotate or move relative to the upper piece.
[0007] A further pair of push rods can slide on the swing assembly to achieve position adjustment.
[0008] Furthermore, the loading body is provided with a grippable handle.
[0009] By implementing the utility model, when the punching mechanism moves upward, the transmission mechanism drives the slider forward to push the punching blank on the transfer slide rail forward to the lower die of the punch press, and the limiting device limits and resists the punching blank pushed from the transfer slide rail, so that the punching blank falls on the fixed position of the lower die. When the punching mechanism moves downward to punch, the transmission mechanism drives the slider backward to make the bottom punching blank on the punching blank stacking mechanism fall onto the transfer slide rail, and this is repeated to realize automatic loading and punching of the punching blank.

DETAILED DESCRIPTION
[0013] Embodiments of the present utility model: Figure 1 to Figure 2As shown, a motor-driven automatic punching sheet feeding device is used in conjunction with a punch press 1. The punch press 1 is provided with a matching upper die 2 and a lower die 3. The lower die 3 is fixedly arranged, and the upper die 2 is installed on the punching mechanism 4 of the punch press 1. The punching mechanism 4 moves up and down and closes and opens with the lower die 3 to achieve punching, including a pushing mechanism and a limiting device. A workbench 5 is provided on one side of the punch press 1. The workbench 5 is provided with a feeding body 7 including a transfer slide 6 and a punching sheet blank stacking mechanism, wherein the feeding body 7 is box-shaped, and the transfer slide 6 is arranged in the feeding body 7. The punching sheet blank stacking mechanism includes an opening arranged on the upper end surface of the feeding body 7 and a stopper 8 arranged around the opening to limit the punching sheet blank 12. The opening is located on the transfer slide The distance between the bottom of the opening and the slide rail 6 is greater than the thickness of a sheet blank but less than the thickness of two sheet blanks. The blocking rods 8 arranged around the opening limit the stacked sheet blanks 12 in all directions so that the sheet blanks 12 pass through the opening and fall one by one on the transfer slide rail 6. The pushing mechanism includes a slider 9 that is slidably connected in the feeding body 7 to push the sheet blanks 12 on the transfer slide rail 6. The transmission mechanism is connected to the stamping mechanism, including a push-pull member 10 arranged on the stamping mechanism 4, and a swinging assembly 11 transferred to the punching machine 1. The swinging assembly 11 has a limiting hole 12 that matches the push-pull member 10 with a clearance. When the push-pull member 10 moves up and down with the stamping mechanism 4, it blocks the push-pull member from the inner wall of the limiting hole 12. The swing assembly 11 swings back and forth along the transition, and one side of the slider 9 has a stopper 13 that passes through the feeding body 7. A pair of push rods 14 that cooperate with the stopper 13 are provided at the bottom of the swing assembly 11, and the stopper 13 is located between the two push rods 14. When the swing assembly 11 swings, the two push rods 14 push the stopper 13 in turn to realize the reciprocating forward and backward sliding of the slider 9. When the punching mechanism 4 moves up, it pulls the swing assembly 11 to swing up, and the push rod 14 pushes the slider 9 forward to push the punch blank 12 that falls on the transfer slide rail 6 forward to the lower die 3 of the punch press 1. The limiting device includes a U-shaped retaining ring 15. The punch press 1 is provided with a guide column. The U-shaped retaining ring 15 is arranged on the outer periphery of the lower die 3 and is slidably connected to the guide column. The open end of the U-shaped retaining ring 15 is connected to the lower die 3. The output ends of the transfer slide rail 6 are opposite, and the guide column outer sleeve is provided with a spring 16 for elastically supporting the U-shaped retaining ring 15. The punching blank 12 pushed out from the transfer slide rail 6 enters from the open end of the U-shaped retaining ring 15. Since it is blocked and limited in other directions, the punching blank 12 falls on the fixed position of the lower mold 3. When the upper mold 2 moves down for stamping, it drives the U-shaped retaining ring 15 to move down together. When the upper mold 2 moves up, the U-shaped retaining ring 15 moves up and resets under the action of the spring 16. When the stamping mechanism 4 moves down, it drives the slider 9 to prevent it from blocking the opening. The bottom punching blank 12 on the punching blank stacking mechanism falls onto the transfer slide rail 6, and this is repeated. Accurate and automatic loading of punching blanks can be achieved without the need for an additional driving device.
[0014] As a preferred embodiment, the swing assembly 11 includes an upper part 17 and a lower part 18. The upper part 17 is connected to the punch press 1 and cooperates with the push-pull part 10. The push rod 14 is installed on the lower part 18. The lower part 18 is slidably connected or transferred to the upper part 17. The lower part 18 can be rotated or slid relative to the upper part 17 as needed and then fixed with fasteners. The two push rods 14 are slidably connected to the lower part 18 and can slide back and forth to adjust the spacing and then be fastened with fasteners, which facilitates the adjustment of the sliding stroke of the slider 9.
[0015] As a preferred embodiment, the loading body 7 is provided with a grippable handle 19 to facilitate the removal, placement and replacement of the loading body 7 .
