Top punching die for lamp shade

Abstract

The invention relates to a top punching die for a lamp shade. The top punching die comprises an upper template, a lower template, and a guide post connected with the upper and lower templates, wherein a female die is arranged on the upper template; a male die is arranged on the lower template; and the top punching die is characterized in that a supporting plate for placing a product to be punched is arranged on the male die; a discharging plate is arranged in the female die; a die handle is arranged on the upper template; a knockout rod connected with the discharging plate is arranged on the die handle; and a plurality of punching punches and a raising punch are arranged on the male die. The plurality of punching punches and the raising punch for punching salient points are arranged on the male die, so that a round hole on the top of the lamp shade and the salient points are punched and formed at a time, the defect that the position of a repeatedly machined side hole is inaccurate is overcome, the product yield is improved, the production efficiency is improved, the production cost and labor intensity are reduced, and the top punching die is reasonable and stable in structure and is suitable for popularization and application.

Description

technical field [0001] The invention relates to a punching die, in particular to a punching die for the top of 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, the top of the semi-finished lampshade is generally punched with a single punch or manually punched, which has low work efficiency and high labor intensity, and the position accuracy of the punched hole on the lampshade is low, which is inconvenient for positioning. , so that the position deviation of the machining hole is large, and it is difficult to cooperate ...
