Problems solved by technology

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 side 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 and the positioning is not accurate. Convenient, difficult to determine, large deviation angle, which leads to the scrapping of the entire product and increases the production cost

Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] see figure 1 and figure 2 , the present embodiment is a side punching die for punching side holes on the side of the lampshade, which includes an upper template 10 and a lower template 20 and a guide post 30 connecting the upper and lower templates, on the upper surface of the upper template 10 Die Bing 12 is installed, and its lower surface is equipped with hold-down plate 11 by buffering part 13, and what this buffering part 13 has adopted is uric acid, plays buffering effect, and reaches to press the lampshade to be punched tightly. Five pusher columns 14 are evenly arranged around the upper template 10, which correspond to the five punching needle sliders 22 installed on the lower template 20, so that they can be evenly divided into f...

Abstract

The invention relates to a side punching die, which comprises an upper template, a lower template, and a guide post connected with the upper and lower templates, wherein a supporting plate for placing a product to be punched, a plurality of punching needle slide blocks, and a reset mechanism for resetting the punching needle slide blocks are arranged on the lower template; one ends of the punching needle slide blocks are connected with the reset mechanism, and a punch used for punching the side of the product to be punched is arranged at the other ends of the punching needle slide blocks; and a pressing plate which corresponds to the supporting plate and a pushing post which corresponds to a punching slide block and drives the slide block to move through pressing are arranged on the upper template. According to the plurality of punching needle slide blocks, a plurality of sides are punched at a time, multiple holes on the side face can be machined through one-step machining, the defect that the position of a repeatedly machined side hole is inaccurate is overcome, the product yield is improved, the production cost and labor intensity are reduced, and the side 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 side 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, the side of the semi-finished lampshade is usually punched with a single punch or manually, which has low work efficiency and high labor intensity, and the position accuracy of the punched hole on the lampshade is low and the positioning is not accurate. It is convenient, difficult to determine, and the deviation angle is large, which leads to the scrapping of the enti...
