Description

Technical Field

[0001] This utility model belongs to the field of stamping blanking technology, and specifically relates to a stamping blanking mechanism. Background Technology

[0002] Blanking dies are a common piece of equipment in the production process, used to cut parts or blanks from sheet metal. A typical blanking die includes an upper die, upper die blocks mounted on the upper die holder, a lower die holder, and lower die blocks mounted on the lower die. The upper and lower die blocks cut the parts or blanks. Guide pillars and bushings are generally used to position the upper and lower die holders, allowing the upper die to move up and down, positioning it above or away from the lower die, thus achieving the stamping operation.

[0003] Some workpieces have multiple corner points, resulting in a large contact area between the punch and die after stamping. This often makes it difficult to unload the workpiece, thus affecting the stamping effect. Utility Model Content

At this time, the contouring head can be reset under the action of the spring, thereby removing the formed product from the mold. It is easy to blank workpieces with more corners, thus improving the stamping effect.

[0005] This utility model provides the following technical solution: a stamping blanking mechanism, including an upper die base, a die cavity on the upper die base, and a plurality of corner contouring components on the die cavity. The corner contouring components are located at the corners of the die cavity. Each corner contouring component includes a connecting inner sleeve, a telescopic connecting rod, and a contouring head. The outer end face of the connecting inner sleeve is flush with the die cavity surface. The contouring head is slidably connected to the connecting inner sleeve. The connecting inner sleeve is provided with an ejector pin for limiting the position of the contouring head.

[0006] The contour-following head is fixedly connected to the telescopic connecting rod, and the telescopic connecting rod is slidably connected within the inner sleeve of the connector.

[0007] The telescopic connecting rod has a spring fixedly connected to one end away from the contoured head, and the other end of the spring is fixed inside the connecting sleeve.

[0008] One end of the ejector pin is slidably connected inside the connecting sleeve, and the other end of the ejector pin is connected to the telescopic connecting rod.

[0009] The upper mold base has an internal groove, and the ejector pin is located in the internal groove.

[0012] The beneficial effects of this utility model are: The corner contouring assembly includes a connecting inner sleeve, a telescopic connecting rod, and a contouring head. After the upper and lower die bases stamp the product, the upper die base can be driven to move upward. At this time, the ejector pin is in a fixed position, which pushes the contouring head in a fixed position. This makes it easy to restrict the position of the formed product by the contouring head, so that the formed product is located at the position of the lower die base. When the upper die base is fully raised, the ejector pin can be driven to move. At this time, the contouring head can be reset under the action of the spring, thereby removing the formed product from the mold. This makes it easier to unload workpieces with many corners and improves the stamping effect.

One end of the ejector pin 3 is slidably connected in the connecting inner sleeve. Inside 21, one end of the ejector pin 3 contacts the end face of the telescopic connecting rod 22, giving the contouring head 23 a floating range. When the telescopic connecting rod 22 slides within the inner sleeve 21, it compresses the spring 24. When the ejector pin 3 pushes against the telescopic connecting rod 22, the telescopic connecting rod 22 can stretch the spring 24 outward. After the upper and lower mold bases are stamped to form the product, the upper mold base 1 can be driven to move upward. At this time, the ejector pin 3 is in a fixed position, pushing the contouring head 23 in a fixed position, which facilitates the restriction of the position of the formed product by the contouring head 23, so that the formed product is located at the position of the lower mold base. When the upper mold base 1 is fully raised, the ejector pin 3 can be driven to move. At this time, the contouring head 23 can be reset under the action of the spring 24, thereby removing the formed product from the mold.
