Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for processing distribution box parts. Background Art

[0002] The stamping die used for processing distribution box spare parts is a tool specially used for stamping metal sheets. It can process metal sheets into the required shape and size by stamping. The stamping die usually consists of an upper die and a lower die. The upper die is fixed on the slider of the punch press, and the lower die is fixed on the workbench. When the slider of the punch press descends, the upper die and the lower die close together to stamp the metal sheet to form the required parts.

[0003] At present, the stamping die used for processing distribution box parts is prone to deviation during long-term use, which affects the processing quality. In addition, it is inconvenient for workers to remove the stamped parts, which affects the processing efficiency.

[0004] In response to the above problems, the present utility model document proposes a stamping die for processing distribution box parts. Utility Model Content

[0008] The upper mold and lower mold are used in conjunction with each other, and a top plate is provided directly above the upper mold. The top plate and the upper mold are connected by multiple telescopic rods. Guide rods are fixedly provided at the four corners of the bottom of the top plate. The upper mold and the lower mold are respectively provided with a first through hole and a second through hole for the corresponding guide rods to pass through;

[0009] Auxiliary positioning assembly, located on the lower die, used to ensure the docking accuracy between the upper die and the lower die;

[0010] The ejector assembly is located on the lower die to allow workers to remove the stamped parts.

[0011] In one possible design, the auxiliary positioning assembly includes two fixed blocks symmetrically fixed on the top of the lower mold, two positioning rods symmetrically fixed on the top of the fixed blocks, and the upper mold is provided with positioning holes for the corresponding positioning rods to pass through.

[0012] In one possible design, the ejection assembly includes an electric push rod fixedly mounted at the center of the bottom of the lower mold, a mounting hole for movement of the telescopic end of the electric push rod is provided at the center of the lower mold, and a push plate is fixedly provided at the telescopic end of the electric push rod.

[0013] In a possible design, the lower die is fixed to the workbench via a base fixed at the bottom, and the top plate is fixed to a slide of the punch press.

[0014] In a possible design, a plurality of buffer springs are fixedly arranged between the top plate and the upper mold.

[0015] In a possible design, lubrication sleeves for improving the smoothness of movement of the guide rod are fixedly provided in both the first through hole and the second through hole.

[0016] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0017] The working principle and usage process of this technical solution are as follows:

[0018] When in use, place the distribution box spare parts at the designated position of the lower die, ensure that the top plate is firmly connected to the slider of the punch press, and the upper and lower dies are in the initial separated state. Start the punch press, and the slider of the punch press drives the top plate to move downward. The top plate pushes the upper die downward through the telescopic rod. The guide rod passes through the first through hole and the second through hole to ensure that the upper and lower dies are aligned. The positioning rod of the auxiliary positioning assembly passes through the positioning hole of the upper die to further ensure the docking accuracy of the upper and lower dies. The upper and lower dies are closed to complete the stamping of the spare parts. After the stamping is completed, the slider of the punch press drives the top plate to move upward, and the upper die rises accordingly. The electric push rod of the ejection assembly is started, pushing the push plate up, and ejecting the stamped parts out of the lower die. The workers remove the stamped parts for subsequent processing or packaging.

[0019] The utility model has the following beneficial effects:

[0020] The utility model ensures the docking accuracy of the upper and lower dies during the stamping process through the setting of the auxiliary positioning component, thereby ensuring the dimensional accuracy and shape consistency of the stamped parts. The design of the ejection component enables the stamped parts to be easily ejected from the lower die, making it easy for workers to remove them, reducing the time and labor intensity of taking out the parts.

[0021] The utility model reduces the impact and vibration during the stamping process by arranging a buffer spring between the top plate and the upper die, thereby protecting the stamping die and extending its service life. In addition, the lubricating sleeves arranged in the first through hole and the second through hole improve the smoothness of the movement of the guide rod in the hole, reduce friction and wear, and further improve the working efficiency and precision of the stamping die.
