Description

Technical Field

[0001] The utility model relates to the field of metal plate processing equipment, in particular to a curved edge processing die for metal plates. Background Art

[0002] In the processing of metal sheets, it is necessary to set a predetermined curved edge at certain positions of the metal sheets. The existing processing generally uses a bending machine for bending, which has a low processing cost, but there is deformation caused by processing stress, and the structural strength is also poor. The main production expenditure is labor expenditure, and the corresponding production efficiency is also low. Utility Model Content

[0003] The main purpose of the utility model is to propose a curved edge processing mold for metal plates, aiming to realize the curved edge processing of metal plates by designing an integrated processing mold, which has good processing stability and stable structural strength. At the same time, it is easy to demould, effectively improving production efficiency.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a curved edge processing die for metal plates, comprising:

[0005] A lower mold, wherein a vertically sliding support seat is provided in the middle of the lower mold, the support seat is used to support the plate, a fixed seat is provided on one side of the support seat, the fixed seat is provided with a first molding surface, and a horizontally sliding seat is provided on the other side of the support seat, and the side wall of the sliding seat facing the support seat is provided with a second molding surface;

[0006] An upper die, wherein a stamping seat is provided at a position of the upper die opposite to the support seat, and a third molding surface and a fourth molding surface matching the first molding surface and the second molding surface are respectively provided on two sides of the stamping seat;

[0007] A push seat, the push seat is arranged adjacent to the punching seat;

[0008] When the upper mold and the lower mold are closed, the push seat can drive the sliding seat to move toward the fixed seat, and at the same time the first molding surface and the third molding surface move closer to each other, and the second molding surface and the fourth molding surface move closer to each other.

[0009] In the actual design, the support of the flat plate is realized by the support seat. When the upper die and the lower die are closed, the punching seat and the support seat are against each other to clamp and position the plate. When the punching seat continues to move downward, the corresponding first forming surface and the third forming surface are arranged oppositely. At the same time, the push seat and the sliding seat are against each other, and the first forming die and the second forming surface are brought close to each other. At this time, the third forming surface and the fourth forming surface are brought close to each other, and a predetermined curvature is formed on both sides of the plate.

[0010] During demoulding, the punching seat and the push seat move upward, the corresponding supporting seats slide upward, and the sliding seat moves away from the fixed seat, thereby realizing the demoulding of the plate and avoiding partial drawing of the curved edge (even if the curvature of the first molding surface and the third molding surface is large, there will be no problem of mold jamming), which would lead to product damage. The processing steps are simple and stable, and it is a reference model for this type of mold, which improves the production applicability (for example, replacing the first molding surface and the third molding surface).
