Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: a stamping mechanism for automatic feeding, including a frame 1, a spring 2, a support table 3, a material 4, a base 5, a sliding frame 6, a cylinder 7, a piston rod 1 8, a clamping block 9, a support frame 10, a piston rod 2 11, a clamping block 12, an electromagnet 13, an air pipe 14, an air bag 15, and a suction cup 16.

[0026] Example 1

[0027] The automatic feeding stamping mechanism has a simple feeding process and can work continuously, reducing manual intervention and being more efficient. Specifically:

[0028] A spring 2 is installed on the bottom surface of the inner wall of the frame 1, and a support 3 is connected to the upper surface of the spring 2. Materials 4 are placed on the upper surface of the support 3. A base 5 is connected to the side surface of the frame 1, and a slide groove is provided on the upper surface of the base 5. A sliding frame 6 is provided on the upper surface of the base 5, and a block 9 is installed on the lower surface of the sliding frame 6. The block 9 is embedded and slidably installed in the slide groove provided on the upper surface of the base 5. A cylinder 7 is installed on the side surface of the sliding frame 6. Two piston rods 8 are provided inside the sliding frame 6, and the piston rods The side surface of the frame 18 is connected to the cylinder 17, the upper surface of the sliding frame 6 is installed with a support frame 10, the interior of the support frame 10 is installed with an air pipe 14, and the lower surface of the support frame 10 is installed with an air bag 15, the upper surface of the air bag 15 is connected to the air pipe 14, and the lower surface of the air bag 15 is installed with a suction cup 16, the front surface and the upper surface of the frame 1 are provided with openings, the opening of the upper surface of the frame 1 corresponds to the position of the suction cup 16, one end of the air pipe 14 is connected to the piston rod 11, and the other end of the air pipe 14 is connected to the air bag 15;

[0029] The automatic feeding punching mechanism is used for feeding the material 4 of the punching machine, such as Figure 1 As shown, first, the staff stacks the material 4 from the front surface of the frame 1 on the pallet 3. The weight of the material 4 presses the pallet 3, so that the spring 2 set on the lower surface of the pallet 3 is squeezed, and the top of the stacked material 4 is parallel to the upper surface of the frame 1, as shown in FIG. Figure 1 As shown, the cylinder 7 is turned on, so that the piston rod 18 inside the sliding frame 6 moves to the left, driving the clamping block 12 to move at the same time. At the same time, when the clamping block moves to the left 12, the piston rod 11 installed on the side surface of the clamping block 12 is driven to move at the same time, so that the air flow inside the air pipe 14 is pumped by the piston rod 11, and the gas flows back from the inside of the airbag 15 to the bottom of the inner cavity of the support frame 10. Therefore, the airbag 15 on the lower surface of the support frame 10 is compressed upward, and then the suction cup 16 on the lower surface of the airbag 15 drives the material 4 upward. At this time, the clamping block 12 continues to move to the side of the material 4, and the electromagnet 13 set on the lower side of the clamping block 12 will be turned on by the timer and then rotated upward, so that the clamping block 12 absorbs the material 4, and the anti-sliding block set on the inner wall surface of the clamping block 12 increases the friction force and fixes it. Then the clamping block 12 continues to move, so that the airbag 15 continues to drive the suction cup 16 upward, and the suction cup 16 loses suction on the material 4, and then the suction cup 16 will not block the movement of the clamping block 12. Figure 3 As shown, the material 4 enters the punching machine, and the cylinder 7 installed on the front surface of the base 5 pushes the clamping block 9 to slide in the slide groove set on the upper surface of the base 5, and at the same time makes the sliding frame 6 drive the clamping block 12 to move, so that the material 4 moves in the punching machine to complete the punching.

[0030] Example 2

[0031] On the basis of Example 1, the automatic loading stamping mechanism can automatically unload materials, and the waste materials are stacked as a whole, reducing the subsequent manual sorting process, specifically:

[0032] The lower end side surface of the support frame 10 is connected with a piston rod 11, one end of the piston rod 18 is installed with a clamping block 12, and the lower surface of the inner wall of the clamping block 12 is provided with an electromagnet 13, the lower surface of the electromagnet 13 is provided with a timer, and the timer can control the switch of the electromagnet 13, and the middle part of the clamping block 12 is provided with a clamping groove, and the lower half of the clamping groove can rotate;

[0033] After stamping, Figure 2As shown, the cylinder 7 continues to push the clamping block 9 to drive the sliding frame 6 to move, so that the clamping block 12 drives the remaining waste after the stamping is completed, and drives the waste to both sides of the frame 1. At this time, the timer installed under the electromagnet 13 reaches the preset time, and then the electromagnet 13 in the clamping block 12 loses its magnetic force, so that the magnet set at the front end of the electromagnet 13 loses attraction with the waste, and the waste falls on the side of the frame 1, which is convenient for subsequent cleaning. Then, under the control of the cylinder 7, the clamping block 12 continues to move, and the piston rod 11 on the rear surface of the clamping block 12 is pushed inward, so that the airbag 15 moves downward. After the clamping block 12 moves back to its original position, the airbag 15 presses the suction cup 16 downward, so that it adsorbs a new piece of material 4 again, and then repeats the operation as shown above, so that continuous work can be carried out, thereby improving work efficiency.

[0034] Working principle: When using the automatic loading stamping mechanism, it can automatically load and unload materials, improve processing efficiency, and stack waste at fixed points for easy sorting, increasing overall practicality.

[0035] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
