Description

Technical Field

[0001] This utility model belongs to the technical field of stamping equipment, specifically relating to a pneumatic ejection device for stamping dies. Background Technology

[0002] In modern industrial production, stamping dies, with their high efficiency and precision, are widely used in numerous fields such as automobile manufacturing, electronic equipment, and home appliances. To meet the appearance quality and performance requirements of products, many stamped parts need to have smooth, flat surfaces. However, when stamping dies produce workpieces with smooth surfaces, after stamping, due to the high degree of contact between the workpiece surface and the die, and the lack of effective gripping points, it is difficult for workers to quickly and easily pick up the workpiece. Currently, workers typically use manual picking or tools to remove the workpiece. These methods not only consume a lot of manpower and time, but also easily cause scratches and wear on the workpiece surface during operation, reducing the product qualification rate and resulting in low production efficiency, failing to meet the needs of large-scale industrial production. Furthermore, some existing auxiliary picking devices are complex in structure, costly, and inconvenient to install and maintain, making them difficult to widely apply in actual production. Therefore, how to design a stamping die that can effectively solve the problem of picking up smooth, flat stamped workpieces and improve production efficiency and product quality has become an urgent technical problem to be solved in this field. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a pneumatic ejector device for stamping dies, which solves the problem of difficult part removal in existing stamping dies. This pneumatic ejector device for stamping dies is designed for smooth-surfaced stamping dies and can improve the efficiency of part removal after stamping without affecting the product surface.

[0004] This utility model discloses a pneumatic ejection device for stamping dies, including a stamping bottom die, a stamping head, and a compressed gas supply device. The stamping head is movably mounted above the stamping bottom die. The top surface of the stamping bottom die is provided with a stamping cavity, which includes a central recess and a stepped surface surrounding the outer periphery of the recess. The depth of the recess is greater than the depth of the stepped surface. A strip groove is provided in the middle of the bottom surface of the recess, and multiple air inlets are provided on both sides of the strip groove. A connecting air passage is provided inside the stamping bottom die, which connects the air inlets and the compressed gas supply device.

[0005] Furthermore, a plurality of positioning posts are provided at the inner edge of the stepped surface, and the plurality of positioning posts are used for positioning the workpiece to be stamped.

[0006] Furthermore, anti-foolproof notches are provided at the diagonal positions of the stepped surface.

[0007] The pneumatic ejection device for stamping dies features a strip groove in the center of the recessed bottom surface of the stamping die, with multiple air inlets on both sides of the groove. An internal connecting air passage connects to a compressed gas supply device. After stamping, the compressed gas supply device delivers compressed gas to the air inlets through the connecting air passage. The gas ejected from the air inlets acts on the bottom surface of the workpiece, generating sufficient thrust to lift the smooth, tightly fitted workpiece from the stamping cavity. Compared to manual removal or tool-assisted removal methods in the prior art, this device eliminates direct human contact with the workpiece, avoiding scratches and wear on the workpiece surface during removal, effectively improving product yield. Furthermore, the pneumatic ejection method quickly lifts the workpiece, significantly shortening removal time and improving production efficiency. Simultaneously, the device has a relatively simple structure, lower cost compared to existing complex auxiliary removal devices, and is easier to install and maintain, making it suitable for widespread application in actual production.

Obviously, what is described is only a part of the embodiments of this utility model, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0012] See Figure 1As shown, this utility model discloses a pneumatic ejection device for stamping dies, including a stamping bottom die 1, a stamping head, and a compressed gas supply device. The stamping head is movably mounted above the stamping bottom die 1. The top surface of the stamping bottom die 1 is provided with a stamping cavity 8. The stamping cavity 8 includes a recessed portion 5 located in the middle and a stepped surface 2 surrounding the outer periphery of the recessed portion 5. The depth of the recessed portion 5 is greater than the depth of the stepped surface 2. A strip groove 4 is provided in the middle of the bottom surface of the recessed portion 5. Multiple air inlets 3 are provided on both sides of the strip groove 4. A connecting air passage is provided inside the stamping bottom die 1, and the connecting air passage is connected to the air inlets 3 and the compressed gas supply device.

[0013] The pneumatic ejection device for the stamping die features a strip groove 4 in the center of the recessed portion 5 of the stamping die 1, with multiple air inlets 3 on both sides of the groove 4. These inlets are connected to a compressed gas supply device via an internal connecting air passage. After stamping, the compressed gas supply device delivers compressed gas to the air inlets 3 through the connecting air passage. The gas ejected from the air inlets 3 acts on the bottom surface of the workpiece, generating sufficient thrust to lift the smooth, flat workpiece, which fits tightly with the die, from the stamping cavity 8. Compared to manual removal or tool-assisted removal methods in the prior art, this device eliminates the need for direct human contact with the workpiece, avoiding scratches and wear on the workpiece surface during removal, effectively improving product qualification rate. Furthermore, the pneumatic ejection method quickly lifts the workpiece, significantly shortening removal time and improving production efficiency.

[0014] Multiple positioning posts 6 are provided at the inner edge of the stepped surface 2, and the multiple positioning posts 6 are used for positioning the workpiece to be stamped.

[0015] These positioning pins 6 provide precise positioning for the workpiece during stamping, ensuring its accurate placement within the stamping cavity 8. This prevents stamping defects caused by workpiece placement errors, improves the dimensional accuracy and quality stability of stamped products, and reduces the scrap rate. Simultaneously, precise positioning makes the stamping process more stable, reduces mold wear, extends mold life, further lowers production costs, and increases production efficiency.
