Description

Technical Field

[0001] This invention relates to the field of white goods, and in particular to a set of stamping dies for processing the convex bulges of sheet metal parts for white goods. Background Technology

[0002] In the white goods industry, back panels and other accessories typically require the connection of an upper and lower panel. Between these panels are multiple protrusions of varying heights, necessitating sufficient space. Current methods involve installing column nuts between the panels, with one end attached to one panel and the other secured with bolts and the column nut. However, this method requires removing the upper and lower panels and placing them on a separate processing platform for the column nut installation. It also necessitates purchasing additional standard parts, making assembly cumbersome and costly. Therefore, a more convenient and cost-effective approach is needed. Summary of the Invention

[0003] This invention provides a convex stamping die equipment for convex processing of back plate sheet metal parts. The stamping die set can be installed on the processing platform to perform convex processing on the sheet metal, thereby improving processing efficiency and reducing production costs.

[0004] An embodiment of the present invention provides a punching die device for a convex hull, including an upper movable plate, a lower movable plate, and a support plate placed between the upper movable plate and the lower movable plate. An upper pressure plate for pressing the sheet metal to be punched and a lower pressure mechanism for supporting the upper die assembly of the punching die kit are installed below the upper movable plate. A lifting mechanism is installed on the lower movable plate and the lifting mechanism is connected to the lower die assembly of the punching die kit. The sheet metal to be punched is placed on the support plate.

[0005] The sheet metal to be stamped is placed at a predetermined position on the support plate. The upper moving plate presses down, and the lower pressing mechanism presses down accordingly, gradually pressing the upper die assembly of the stamping die kit. At the same time, the lower pressing plate also gradually presses the sheet metal to be stamped. When the upper moving plate is ready to press down, the sheet metal to be stamped on the support plate is pressed into place. The lower moving plate moves upward, driving the lifting mechanism to lift upward. The lifting mechanism lifts the lower die assembly of the stamping die kit upward, forming a contoured protrusion on the sheet metal to be stamped.

[0006] Furthermore, the lower die assembly of the stamping die kit includes a first lower die and a second lower die that is slidably installed in the first lower die through hole of the first lower die. The upper die assembly of the stamping die kit includes a first upper die disposed above the first lower die and the second lower die, a second upper die that is slidably installed in the first upper die through hole of the first upper die, and a third upper die that is slidably installed in the second upper die through hole of the second upper die. The upper part of the first lower die is a frustum-shaped structure, and the lower part is a cylindrical structure. The upper part of the second lower die is a frustum-shaped structure, and the lower part is a cylindrical structure. The first upper die is a cylindrical structure with a first upper die through hole inside, and the lower part of the first upper die through hole has a connection with the first lower die. The upper die has an inner frustum structure that matches the frustum structure of the first upper die. The upper cavity of the first upper die through hole is a cylindrical cavity. The second upper die is nested in the first upper die through hole. The lower part of the second upper die through hole is a frustum cavity that matches the frustum structure of the second lower die. The upper part of the second upper die through hole is a cylindrical cavity. The third upper die is nested in the upper cylindrical cavity of the second upper die through hole. The pressing mechanism presses the first upper die, the second upper die, and the third upper die together to ensure stability during the stamping process. The lifting mechanism is divided into two parts: one part is used to lift the first lower die and the second lower die to form a first protrusion, and the other part is used to further lift the second lower die to form a second protrusion.

[0007] During operation, the first upper die, the second upper die, and the third upper die press down on the sheet metal. After the first lower die and the second lower die are lifted in sequence by the lifting mechanism, the first lower die is ejected first, forming the first convex bud corresponding to the first lower die. Then, based on the first convex bud, the second lower die is ejected, forming the second convex bud corresponding to the second lower die. When the first convex bud is ejected, the upper surface of the second lower die and the upper surface of the first lower die remain flat, so that the upper surface of the formed first convex bud is flat. Afterward, the second lower die continues to eject, forming the second convex bud. The lower surface of the third upper die and the upper surface of the second lower die work together to make the top surface of the second convex bud flat.

[0008] Furthermore, the angle of the frustum-shaped structure of the first lower mold is 35-55 degrees, the angle of the frustum-shaped inner cavity of the through hole of the first upper mold is 35-55 degrees, and the angle of the frustum-shaped structure of the first lower mold is the same as the angle of the frustum-shaped inner cavity of the through hole of the first upper mold.

[0009] Furthermore, the angle of the frustum-shaped structure of the second lower mold is 35-55 degrees, the angle of the frustum-shaped inner cavity of the through hole of the second upper mold is 35-55 degrees, and the angle of the frustum-shaped structure of the second lower mold is the same as the angle of the frustum-shaped inner cavity of the through hole of the second upper mold.

[0010] Furthermore, the lower part of the first lower die has a flange shoulder, the lower part of the second lower die has a flange shoulder, and the inner cavity of the first lower die and the flange shoulder of the second lower die slide in a vertically sliding fit.

[0011] Furthermore, the upper part of the second upper mold has a flange shoulder, and the inner cavity of the first upper mold and the flange shoulder of the second upper mold slide together vertically.

[0012] Furthermore, the third upper mold is a combination structure of two columnar shapes, one larger than the other, with the inner cavity of the second upper mold and the upper columnar structure of the third upper mold sliding together vertically.

[0013] Furthermore, the first lower die and the second lower die are independently connected to the lifting mechanism. By connecting to the lifting mechanism, the first lower die and the second lower die can be independently lifted to form a protrusion on the plate corresponding to the first lower die and the second lower die.

[0014] Furthermore, an elastomer is installed between the lower pressure plate and the upper moving plate. This elastomer is a urethane rubber structure, and the urethane rubber acts as a buffer when the lower pressure plate is pressed down.

[0015] Furthermore, according to some embodiments of the present invention, the pressing mechanism includes an elastic body, the pressing mechanism includes a pressing elastic body, the pressing elastic body is placed at the rear end of the pressing mechanism, and the front end of the pressing mechanism is a metal material structure. When the pressing mechanism gradually presses down to the bottom and presses the upper die assembly of the stamping die kit onto the upper surface of the plate to be stamped on the support plate, during this process, the pressing mechanism gradually presses the plate to be stamped. Here, the elastic body can be a spring, and the elastic force is pre-adjusted.
