Scaffold type lens collar punching die of tablet personal computer

Abstract

The invention discloses a scaffold type lens collar punching die of a tablet personal computer. The scaffold type lens collar punching die of the tablet personal computer comprises an upper die and a lower die, wherein the upper die and the lower die are mutually positioned and inosculated through a guide column fixed on the upper die; the upper die comprises an upper padding plate, a punch retainer plate and a discharge plate, all of which are sequentially stacked and then are connected and fixed on an upper die plate through dowels and screws, and the punch retainer plate is provided with a piercing punch with a flanging molding platform; a lower concave die with a locating device is embedded in a concave die plate of the lower die, and is provided with a waste discharge hole corresponding to the piercing punch; and the left side of the waste discharge hole of the lower concave die is provided with a locating plate tank vertical to the concave die plate. In such a way, production procedures can be simplified so as to make the actual production more convenient and rapider, meanwhile, more manpower and material resources are saved, and the scaffold type lens collar punching die is suitable for flow line production of products and has the advantages of saving production cost and greatly improving the production efficiency of enterprises.

Description

technical field [0001] The invention relates to the field of punching dies, in particular to a punching die for a tablet computer bracket type lens ring. Background technique [0002] Stamping dies are dies used for sheet metal stamping and blanking separation, including punching dies, bending dies, deep drawing dies, and hole turning dies. In the stamping die, the sheet is formed through the mold cavity, and the sheet is separated or cut through the punching edge of the stamping die. The most commonly used stamping die has only one station to complete a production process. In order to improve productivity, multiple stamping processes, such as blanking, deep drawing, punching, trimming and other processes, can be designed on one stamping die, so that the sheet can complete multiple stamping processes at one station. The mold is called a compound mold. [0003] Stamping dies usually include upper die, lower die, upper die fixing plate, lower die fixing plate, guiding devic...

AI Technical Summary

Problems solved by technology

The tablet computer bracket lens ring on the existing market requires high dimensional accuracy and molding interface for its volume and assembly requirements. The existing stamping die has low molding efficiency and low yield, which greatly increases the production cost and wastes resources.
