Automatic stamping die for inverse-hemming aluminum foil meal box

Abstract

The invention discloses an automatic stamping die for an inverse-hemming aluminum foil meal box, and belongs to the technical field of stamping dies. The automatic stamping die for the inverse-hemming aluminum foil meal box comprises a base, wherein a spring replacement assembly is arranged at the upper end of the base; a movable frame is arranged at the upper end of the spring replacement assembly; a connecting rod is arranged at the upper end of the movable frame; a stamping die core is arranged at the bottom end of the movable frame; a fixed die is arranged at the bottom end of the stamping die core; the spring replacement assembly comprises a limiting device, a fixed plate, a movable block, sleeves, limiting springs, mounting boxes and mounting insertion blocks; the sleeves are symmetrically arranged at the upper end of the base; the limiting springs are arranged in the sleeves; the mounting insertion blocks are symmetrically arranged at the two ends of the limiting springs; and the mounting boxes are arranged on the surfaces of the mounting insertion blocks. According to the automatic stamping die for the inverse-hemming aluminum foil meal box provided by the invention, by arranging the spring replacement assembly, the convenience of replacing the limiting springs is improved, the stamping quality is guaranteed, the working stability is improved, manpower resources are saved, and the working quality is improved.

Description

technical field [0001] The invention belongs to the technical field of stamping molds, and in particular relates to an automatic stamping mold for reverse-rolled aluminum foil lunch boxes. Background technique [0002] Stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to a material at room temperature to separate or plastically deform it to obtain the required parts. [0003] The existing technology has the following problems: [0004] 1. The existing aluminum foil lunch box stamping dies cannot easily replace the springs during use. When the springs are weak, the stamping quality cannot be guaranteed, which affects the product qualification rate, reduces product quality, and increases production costs; [0005] 2. The e...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing aluminum foil lunch box stamping die cannot easily replace the spring during use. When the spring is weak, the stamping quality cannot be guaranteed, which affects the product qualification rate, reduces product quality, and increases production costs;

[0005] 2. It is difficult to install the existing stamping cores, and each core needs to be fixed separately, which affects the installation efficiency of the cores, wastes human resources, cannot guarantee the convenience of installation, and is difficult to operate;

[0006] 3. The stamped lunch box is driven by the moving aluminum foil to leave the fixed mold. During the detachment process, the lunch box is prone to collision and flying out, which affects the collection effect of finished products, and is easy to cause product damage and affect production efficiency.
