[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] like Figures 1 to 5As shown, a stainless steel plate punching die in one embodiment of the present invention includes a die body 1. The bottom surface of the die body 1 is provided with two mounting bosses, each of which has a mounting hole. The mounting bosses and mounting holes allow the die body 1 to be mounted and fixed for convenient use. A punching hole 101 is formed in the die body 1.

[0028] A frame 7 and a hydraulic cylinder 8 are provided above the die body 1. The frame 7 is the main structure of the entire stamping device and can be used to install the die. The hydraulic cylinder 8 is fixedly mounted on the frame 7. The bottom end of the hydraulic cylinder 8 is fixedly connected to a punch head 9 that matches the punching hole 101. The hydraulic cylinder 8 can drive the punch head 9 to move to complete the stamping action.

[0029] Specifically, the mold body 1 and the hydraulic cylinder 8 are both installed on the frame 7. When in use, the stainless steel plate is placed above the mold, and the hydraulic cylinder 8 is used to drive the punching head 9 to move, and the stainless steel plate can be punched when it comes into contact with the punching head.

[0030] like Figure 3 As shown, a movable groove 102 is provided inside the mold body 1, and a vertical groove 103 is provided on the upper end surface of the mold body 1. The vertical groove 103 is vertically arranged above the movable groove 102 and is connected with the movable groove 102. A discharge port 104 is provided on the side wall of the mold body 1. The discharge port 104 is arranged below the punching hole 101 and is respectively connected with the punching hole 101 and the movable groove 102. The stainless steel waste generated by punching can fall into the inside of the discharge port 104 through the punching hole 101. The discharge port 104 has a certain slope, which can make the waste fall out.

[0031] like Figure 1 、 Figure 2 and Figure 4 As shown, a shaped block 2 is movably mounted within the movable groove 102. This block 2 is capable of moving within the movable groove 102, and its upper end face has a slope. A spring 3 is fixedly connected to the shaped block 2, the other end of which is fixedly attached to the movable groove 102. A pressure rod 4 is movably mounted within the vertical groove 103, and is fixedly connected to the hydraulic cylinder 8 via a connecting assembly. When the hydraulic cylinder 8 operates, it drives the pressure rod 4 to move synchronously, and its lower end face has a slope that matches that of the shaped block 2.

[0032] The connecting assembly comprises two sets of curved plates 401 hinged to the compression rod 4. Each of the curved plates 401 has a through-hole, into which a bolt 402 is inserted. Nuts 403 are threadedly connected to the bolts 402. The two curved plates 401 fit snugly against the exterior of the hydraulic cylinder 8. The bolts 402 and nuts 403 engage to lock the curved plates 401 against the surface of the hydraulic cylinder 8, thereby connecting the compression rod 4 to the hydraulic cylinder 8.

[0033] Specifically, by utilizing the coordination of the pressure rod 4 and the slope of the special-shaped block 2, when the pressure rod 4 moves downward, it can push the special-shaped block 2 toward the discharge port 104, thereby pushing out the waste stuck in the discharge port 104. At the same time, the special-shaped block 2 can compress the spring 3 during the movement. When the hydraulic cylinder 8 drives the pressure rod 4 to move upward, the accumulated elastic force of the spring 3 can push the special-shaped block 2 to return to its original position.

[0034] like Figure 2 and Figure 5 As shown, a press-inflatable air pump 5 is fixedly connected to the special-shaped block 2. By pressing the press-inflatable air pump 5, an air flow can be generated to blow toward the discharge port 104 to further clean the discharge port 104. The other end of the press-inflatable air pump 5 is fixed inside the movable groove 102, and the press-inflatable air pump 5 is arranged inside the spring 3. When the special-shaped block 2 moves, the press-inflatable air pump 5 can be compressed to output gas. When the special-shaped block 2 is reset, the press-inflatable air pump 5 can be driven to recover.

[0035] To better control the direction of airflow, an outlet pipe 501 is fixedly connected to the output end of the push-to-pump 5. This pipe is L-shaped and can transport the gas output by the push-to-pump 5. The shaped block 2 is provided with a groove 201 and an inclined hole 202 that match the outlet pipe 501. The outlet pipe 501 is positioned within the groove 201 and communicates with the inclined hole 202. This allows the gas output from the outlet pipe 501 to be blown outward along the inclined hole 202, precisely blowing into the interior of the discharge port 104 to remove any metal debris remaining therein.

[0036] like Figure 2 and Figure 3 As shown, the bottom surface of the mold body 1 is provided with a vent hole 105 that communicates with the movable groove 102. A mounting groove is also provided on the bottom surface of the mold body 1, into which a filter plate 6 is fixedly connected. The vent hole 105 allows the push-to-pump 5 to better absorb air, ensuring its proper function. The filter plate 6 prevents external dust or metal debris from entering the movable groove 102, thereby ensuring internal cleanliness and extending its service life.

[0037] During specific use, the hydraulic cylinder 8 is used to drive the punching head 9 to move, so that the stainless steel plate placed on the mold can be punched. The hydraulic cylinder 8 can also be used to synchronously drive the pressure rod 4 to move. By moving the pressure rod 4 downward and contacting the special-shaped block 2, the special-shaped block 2 can be pushed to move into the discharge port 104, and the waste material dropped inside the discharge port 104 can be pushed out. At the same time, the moving special-shaped block 2 can also squeeze the pressing air pump 5, thereby generating airflow. Through the cooperation of the air outlet pipe 501 and the inclined hole 202, the airflow can be blown into the discharge port 104 to blow away the metal debris inside the discharge port 104, thereby ensuring the use state of the mold.

[0038] The stainless steel plate punching die of the utility model is provided with a movable groove, a vertical groove and a discharge port on the die main body, and cooperates with the special-shaped block, the spring and the pressure rod. The special-shaped block can be moved toward the discharge port under the drive of the hydraulic cylinder, thereby pushing out the waste stuck in the die during the stamping process, cleaning the inside of the die, avoiding affecting the subsequent stamping process, and ensuring the stable progress of the stamping work. In addition, the die does not need to be cleaned and maintained manually, and is highly safe.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0040] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
