Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figures 1-6The present invention provides the following technical solution: an automated auxiliary feeding structure for a punch press, including a support base 1, with universal self-locking wheels 2 provided at the four bottom corners of the support base 1, and support slide rods 3 provided at the four top corners of the support base 1, with a top plate 4 connected to the top of the four support slide rods 3. A lifting screw 5 is rotatably installed between the support base 1 and the top plate 4. A first forward and reverse motor 6 is installed at the top of the top plate 4 to drive the lifting screw 5. A lifting plate 14 is threadedly connected to the lifting screw 5. The lifting plate 14 is slidably connected to four support slide rods 3. When in use, the device is pushed to the vicinity of the punch press, and the No. 1 forward and reverse motor 6 is started in forward rotation mode. The lifting screw 5 drives the lifting plate 14 to move upward, so that the lifting plate 14 is higher than the processing table of the punch press.

[0021] It also includes a conveying mechanism, a pushing mechanism, and a clamping mechanism 19; The conveying mechanism is disposed on one side of the lifting plate 14 via its included connecting plate 8, for conveying the plate onto the lifting plate 14; The pushing mechanism is mounted on the connecting plate 8 and is used to push the sheet metal onto the clamping mechanism 19; The clamping mechanism 19 is located on one side of the lifting plate 14 and is positioned opposite the connecting plate 8, and is used to limit and clamp the plate.

[0022] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, both ends of the top of the connecting plate 8 are provided with symmetrically distributed fixing plates 10. A conveyor belt 11 is rotatably mounted on the fixing plate 10, and a conveyor motor 12 for driving the conveyor belt 11 is provided on one of the fixing plates 10. When the conveyor motor 12 is started, the material on the conveyor belt 11 will be conveyed and dropped onto the top plate 4 to realize the automatic feeding function.

[0023] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the bottom of the lifting plate 14 and the connecting plate 8 are provided with symmetrically distributed reinforcing rods 9, which facilitates the improvement of the stability and support strength of the connecting plate 8.

[0024] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the pushing mechanism includes a cylinder 13 disposed on the connecting plate 8, the telescopic rod of the cylinder 13 is disposed toward the lifting plate 14, and a pushing plate 20 is disposed at the end of the telescopic rod.

[0025] The lifting plate 14 is provided with a slanted slide plate 15 and a positioning plate 16 on the side away from the connecting plate 8. The slanted slide plate 15 is inclined, and a limit edge 21 is provided on the edge of both the lifting plate 14 and the slanted slide plate 15. When the cylinder 13 is activated, the push plate 20 pushes the plate onto the slanted slide plate 15, and the plate slides along the slanted slide plate 15 onto the positioning plate 16 for subsequent clamping and limiting. The positioning plate 16 has a positioning edge 17 on the side away from the inclined slide plate 15. The positioning edge 17 has a limiting function to prevent the plate from shifting.

[0026] Preferably, by Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment, the clamping mechanism 19 includes a support plate 18 symmetrically arranged at the bottom of the positioning plate 16, and clamping slots 22 symmetrically distributed on the positioning plate 16. When in use, the operator pushes the device to the vicinity of the punch press and places the two support plates 18 directly below the punch head. The two support plates 18 are then supported on the processing table below the punch head to facilitate the processing of the sheet metal.

[0027] A bidirectional lead screw 24 is rotatably arranged between the two support plates 18, and a second forward and reverse motor 23 for driving the bidirectional lead screw 24 is installed on one of the support plates 18. The bidirectional lead screw 24 is threaded with symmetrically arranged screw plates 26. The two screw plates 26 can move towards or away from each other through the bidirectional lead screw 24. The top surface of each screw plate 26 is provided with symmetrical extension plates, which pass through the clamping slot 22 respectively. A movable plate 28 is provided on the top of the extension plate on the same side. By starting the forward rotation mode of the second forward and reverse motor 23, the second forward and reverse motor 23 drives the bidirectional lead screw 24 to rotate clockwise and drives the two screw plates 26 to move closer to each other, thereby realizing the clamping action, fixing the sheet metal, and facilitating stamping processing.

[0028] A pair of sliding rods 30 are slidably connected to the movable plate 28. Each sliding rod 30 is connected to a clamping plate 27. The clamping plate 27 is provided with a screw cap 29 that matches the sliding rod 30. The clamping plates 27 on both sides are symmetrically distributed. A spring 31 is wrapped around the outside of the sliding rod 30. The two ends of the spring 31 are in contact with the clamping plate 27 and the movable plate 28, respectively. When the two movable plates 28 move towards each other, the two clamping plates 27 approach each other and press against one side of the plate. During the pressing process, the pressing force will force the sliding rod 30 to move backward, thereby compressing the spring 31. The buffering force of the spring 31 reduces the probability of the plate being deformed or damaged by the pressing, thus improving the pass rate of the plate processing. In addition, if the spring 31 is damaged after long-term use, the corresponding sliding rod 30 can be unscrewed counterclockwise for easy replacement and maintenance.

[0029] A symmetrically distributed positioning rod 25 is also provided between the two support plates 18. The screw plate 26 has a through hole that slides with the positioning rod 25. The positioning rod 25 has a limiting function, which can prevent the screw plate 26 from rotating unnecessarily due to the threaded connection force, so that it can move smoothly and improve the stability of the device.

[0030] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, a controller 7 is provided on the top plate 4. The controller 7 is electrically connected to the first forward and reverse motor 6, the transmission motor 12, the cylinder 13 and the second forward and reverse motor 23 through wires, and can control one of them respectively.

[0031] Components not described in detail in this article are existing technologies.

[0032] The working principle and usage process of this utility model are as follows: When in use, the device is pushed to the vicinity of the punch press, and the No. 1 forward and reverse motor 6 is started in forward rotation mode. The lifting screw 5 drives the lifting plate 14 to move upward, so that the lifting plate 14 is higher than the processing table of the punch press. The entire device is moved so that the positioning plate 16 is directly below the punch head, and the two support plates 18 at its bottom are attached to the processing table of the punch press to provide stable support. Then, the plates to be processed are placed on the conveyor belt 11 in sequence. When the conveyor motor 12 is started, the plates on the conveyor belt 11 will be conveyed and dropped onto the top plate 4 to realize the automatic feeding function. After the sheet falls onto the top plate 4, the cylinder 13 is activated, and the push plate 20 pushes the sheet onto the inclined slide plate 15. The sheet slides along the inclined slide plate 15 onto the positioning plate 16. Then, by activating the forward rotation mode of the second forward and reverse motor 23, the second forward and reverse motor 23 drives the bidirectional lead screw 24 to rotate clockwise, and drives the two screw plates 26 to move closer to each other. The two clamping plates 27 press the sheet onto one side to achieve stable positioning. Then, the punch press can be started for processing.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
