Description

Technical Field

[0001] The utility model belongs to the technical field of punching dies, and in particular relates to a punching arrangement structure. Background Art

[0002] In the field of mechanical manufacturing, punching is a metalworking process commonly used to create holes in sheet metal. This process is accomplished using a punch press and a specifically shaped die (called a punch). As the punch presses down into the sheet metal, it penetrates the material and creates a hole at the designated location. Punching is used to manufacture a variety of products, such as filters, decorative panels, and speaker grilles. Depending on the application, the shape and size of the punch can be varied to create holes of varying sizes and shapes.

[0003] Existing punching dies are generally provided with a discharge channel at the position of the lower die, and the waste materials after punching fall and are discharged from the discharge channel. This structure is relatively stable, but it is necessary to ensure that the lower die has a certain discharge space, and there is generally no other equipment under the lower die. However, in some processing equipment with a more compact layout, sometimes there is not enough space to set up a discharge channel, or there are other equipment structures under the lower die, and the discharge channel cannot be set up. At this time, the conventional practice is to set up an additional manipulator or a purge device to discharge the waste from the punching hole after each punching. This structure has the problems of high cost and insufficient stability. Utility Model Content

[0004] In response to the above-mentioned technical problems, the utility model provides a punching discharge structure to solve the problems of high cost and insufficient stability of the waste discharge structure of the existing punching mold. A new punching discharge structure is designed, which can discharge waste in time after punching and has high stability, avoiding the impact of waste residue on subsequent processing.

[0005] The utility model provides a punching and discharge structure, comprising an upper mold and a lower mold, wherein the upper mold can be lifted and lowered above the lower mold, the bottom surface of the upper mold is provided with a groove, the groove is a bowl-shaped structure, a punching tool is provided inside the groove, the lower mold comprises a forming mold, an ejection block, a guide cylinder and a spring, the top shape of the forming mold is adapted to the groove, a punching hole is provided on the top of the forming mold corresponding to the position of the punching tool, the punching tool is cylindrical, and the outer diameter of the punching tool is the same as the outer diameter of the punching hole The inner diameters are consistent, the guide cylinder is located inside the punching hole, the spring is located inside the guide cylinder, the top of the guide cylinder is opened, one end of the ejector block is slidably inserted into the opening of the guide cylinder, and the other end of the ejector block passes through the punching hole, and the spring abuts against one end of the ejector block. When the upper mold descends, the punching tool abuts against the ejector block and pushes the ejector block into the punching hole, and the spring is compressed; when the upper mold rises, the spring recovers its deformation and drives the ejector block to extend out of the punching hole.

[0006] Furthermore, the lower mold is fixed, and the upper mold is connected to a lifting mechanism.

[0007] Furthermore, the lifting mechanism is a hydraulic mechanism.

[0008] This punching arrangement structure is used for forming holes of a specific shape. Specifically, when performing a punching operation, the upper mold descends, and the groove and the top of the forming mold are used for punching and stretching the external structure of the hole, while the punching tool and the punching hole are used for punching and forming the hole. At this time, the waste material formed after punching abuts between the punching tool and the ejection block, and the punching tool pushes the waste material into the punching hole. When the upper mold rises, the spring deformation recovers and drives the ejection block to extend out of the punching hole, pushing the waste material out of the punching hole to avoid waste material accumulation in the punching hole.
