Description

Technical Field

[0001] This utility model relates to the field of stamping equipment, and in particular to an automatic feeding device for a stamping machine. Background Technology

[0002] A stamping press is a mechanical device that uses pressure to stamp materials. With the development of technology, stamping presses with automatic unloading devices have appeared on the market. After the stamping work is completed, the automatic unloading device will remove the processed workpiece from the mold area according to a predetermined program. This process is usually achieved by suction cups or pusher devices.

[0003] However, the feeding plates of feeding devices on the market usually do not have angle adjustment functions. In actual production processes, there are usually material boxes of various heights in the workshop, and the tilt angle of the feeding plate cannot be adjusted, which makes it inconvenient to adapt to material boxes of different heights and has certain limitations. After searching, it was found that the technical solution provided by the utility model with application number 202222606408.6 also has the above problems. Therefore, there is a need for an automatic feeding device for stamping machines. Utility Model Content

Detailed Implementation

[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] Reference Figure 1-7This utility model discloses an automatic unloading device for a stamping machine, comprising a stamping machine 1, two positioning blocks 2 fixedly connected to the stamping machine 1, a mating block 3 movably connected to the inner surface of each positioning block 2, a threaded rod 4 fixedly connected to each positioning block 2, a nut 5 threadedly connected to the outer surface of each threaded rod 4, the outer surface of the threaded rod 4 movably connected to the mating block 3, the side surface of the nut 5 contacting the mating block 3, a connecting block 6 fixedly connected to the side surface of each mating block 3, a connecting shaft 7 rotatably connected to the inner surface of each connecting block 6, a common unloading plate 8 fixedly connected to each connecting shaft 7, a positioning groove 17 formed on the positioning block 2, and the outer surface of the mating block 3 movably connected to the positioning groove 17.

[0030] Two guide blocks 9 are fixedly connected to the side surface of the feeding plate 8. Sliding sliders 10 are slidably connected to the outer surfaces of both guide blocks 9. Connecting rods 11 are rotatably connected to the inner surfaces of both sliders 10. Lifting blocks 12 are fixedly connected to the side surfaces of both connecting rods 11. Support rods 13 are slidably connected to the outer surfaces of both lifting blocks 12. A common bearing plate 14 is fixedly connected to the two support rods 13. A hydraulic cylinder 15 is fixedly connected to the upper surface of the bearing plate 14. The hydraulic cylinder 15 is electrically connected to an external power source. A push rod 16 is fixedly connected to the output end of the hydraulic cylinder 15. Both ends of the push rod 16 are fixedly connected to the two lifting blocks 12 respectively. A sliding groove 18 is provided on the support rod 13. The outer surface of block 12 is slidably connected to the slide groove 18. The slide groove 18 allows the lifting block 12 to move smoothly. The side surface of slider 10 is in contact with the feeding plate 8. The side surface of the feeding plate 8 is fixedly connected to an anti-detachment block 20. The side surface of the anti-detachment block 20 is fixedly connected to the guide block 9. There are four anti-detachment blocks 20 arranged in a rectangular array. Under the action of the anti-detachment block 20, the slider 10 is prevented from detaching from the guide block 9. A guide groove 19 is provided on the slider 10. The outer surface of the guide block 9 is slidably connected to the guide groove 19, allowing the slider 10 to move smoothly. This allows the feeding plate 8 to be flipped smoothly, thereby adjusting the tilt angle of the feeding plate 8.

[0031] Working principle: By activating the hydraulic cylinder 15 on the support plate 14, the output end of the hydraulic cylinder 15 can extend or retract, thereby causing the push rod 16 to move upward or downward. This, in turn, causes the moving push rod 16 to drive the lifting block 12 and connecting rod 11 to move up or down. The moving connecting rod 11 then causes the slider 10 to slide on the guide block 9, thus causing the moving slider 10 to rotate the unloading plate 8 around the connecting shaft 7 as the central axis. This changes the tilt angle of the unloading plate 8. Once the unloading plate 8 is adjusted to a suitable tilt angle, the hydraulic cylinder 15 is closed. The unloading plate can then be adjusted using a wrench, etc. After unscrewing nut 5 from the threaded rod 4, the connection between the press 1 and the blanking plate 8 is released. Then, pulling the blanking plate 8 removes the blanking plate 8 and the device on it from the press 1. Removing the blanking plate 8 reduces the overall space occupied by the device, making it easier to transfer the press 1 and blanking plate 8 in batches. After the press 1 and blanking plate 8 are transferred to the appropriate position, insert the mating block 3 into the threaded rod 4, then insert the mating block 3 into the positioning groove 17, and finally screw the nut 5 back onto the threaded rod 4. This completes the connection and fixation between the press 1 and the blanking plate 8, which is simple and quick.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
