A method for processing a stamping die for a curved LED display back panel

Abstract

This invention relates to the field of curved display back panel stamping technology, specifically a method for processing a curved LED display back panel stamping die, comprising: a die base, which is the lower structure of the die; a fixed support plate; an arc-shaped metal plate; a connecting block; and a connecting plate. This method for processing a curved LED display back panel stamping die involves setting an arc-shaped metal plate at the bottom of an arc-shaped back panel a, with the top surface of the arc-shaped metal plate evenly conforming to the bottom surface of the arc-shaped back panel a. A through hole matching a stamping head is opened on the top surface of the arc-shaped metal plate. Therefore, when the stamping head stamps, it passes through the through hole, and the arc-shaped back panel a is impacted by the stamping head. Due to the supporting effect of the arc-shaped metal plate, the impact force on the arc-shaped back panel a is evenly distributed. Furthermore, the stamping head is perpendicular to the tangent plane of the curved surface at the punching point, ensuring that the center line of the punched hole is also perpendicular to the tangent plane of the curved surface at the punching point, thus ensuring an ideal punching angle. This method is superior to punching a flattened arc-shaped back panel a, ensuring the quality of the punched arc-shaped back panel a.
