Piercing die for lamp shade

Abstract

The invention relates to a piercing die for a lamp shade, which comprises an upper die plate and a lower die plate, wherein a female die is arranged on the lower surface of the upper die plate; a male die and a retainer plate are arranged on the lower die plate; the male die is sleeved with the retainer plate; the retainer plate is mounted on the lower die plate by a buffer component; a cavity is formed in the female die; a die handle and a knockout rod are arranged on the upper surface of the upper die plate; the knockout rod is mounted on the die handle and extends into the cavity; the lower end face of the female die is inclined; and an inclined surface step adapted to the inclined end face is arranged on the retainer plate. With the adoption of the technical scheme, the piercing die is simple in structure and stable and convenient to operate; one step of punch forming is required only; the deficiency that a position of a side hole is inaccurate due to processing for many times is overcome; in addition, the piercing die is mounted stably with the lamp shade through a retainer plate structure, so that the piercing precision of the piercing die is improved; the product yield is increased; the production efficiency is improved; the manufacturing cost and the labor intensity are reduced; and the piercing die is reasonable and stable in structure, and deserves popularization and use.

Description

technical field [0001] The invention relates to a punching die, in particular to a punching die for a lampshade. Background technique [0002] Cold stamping dies are one of the most widely used molds, including punching dies, blanking dies, bending dies, drawing dies, etc. In recent years, cold stamping dies have become more and more widely used. Cold stamping has low cost, stable product quality, and can process parts with various properties and states. At the same time, its application and generality are also restricted by mold life and production safety. [0003] In the field of lampshade production, at present, semi-finished lampshades are generally punched with a single punch, or manually punched, which is inconvenient to operate, and the positioning of the lampshade shell is not accurate, so that the processed round hole is inclined or the position is wrong. It affects its low work efficiency and increases labor intensity, and the position accuracy of the punched hol...

At the same time, its application and generality are also restricted by mold life and production safety.

[0003] In the field of lampshade production, at present, semi-finished lampshades are generally punched with a single punch, or manually punched, which is inconvenient to operate, and the positioning of the lampshade shell is not accurate, so that the processed round hole is inclined or the position is wrong. It affects its low work efficiency and increases labor intensity, and the position accuracy of the punched holes on the lampshade is low, which is inconvenient to locate, making it difficult to cooperate or install with other products, resulting in the scrapping of the entire product and increasing the Cost of production
